Reasons why factory-made air ducts are more advantageous than on-site production
Reasons why factory-made air ducts are more advantageous than on-site production 1. Comparison between traditional air duct and phenolic air ductThe traditional air supply ducts of central air conditioners are usually made of iron sheet or fiberglass as the inner layer, wrapped with thermal insulation materials, and wrapped with aluminum foil on the outside, which makes the air supply ducts heavy and large, labor-intensive and time-consuming for construction and installation, poor in appearance, low in air tightness, and low in performance. consumes a lot. Traditional air ducts can no longer meet the rapidly growing market demand and people's requirements for high-quality indoor environments.The phenolic color steel composite air duct is made of phenolic foam resin, curing agent, foaming agent and inorganic substances through chemical reaction to form a phenolic foam core material, one side is compounded with antibacterial coated aluminum foil, and the other side is compounded with color steel plates of various colors The air duct made by processing the composite sandwich panel. It has the characteristics of light weight, beautiful appearance, durability and simple construction, thus realizing the best combination of energy saving, environmental protection and beautiful appearance. It is an ideal substitute product for traditional air duct systems.Compared with traditional air ducts, phenolic composite air ducts have the following advantages:1) The phenolic composite air duct has good thermal insulation performance, which can greatly reduce the heat dissipation loss of the air conditioner;2) The phenolic composite air duct has a noise reduction effect. Compared with the metal air duct system, there is no need to set up noise reduction accessories such as noise reduction covers and noise reduction elbows;3) The installation period of the phenolic composite air duct is short, only about 1/5 of the traditional air duct;4) The phenolic composite air duct does not need to reserve construction space, so compared with the traditional air duct, the use of phenolic aluminum foil composite air duct can save 5-8cm of ceiling space;5) The phenolic composite air duct material is non-combustible, the flame retardant grade is Class A, smokeless and non-toxic, and meets the requirements of the national fire protection standard. The thermal conductivity is lower than 0.0220w/m.k, which can reduce the heat dissipation loss of the air conditioner;6) Light weight and high strength, especially the outer surface of the air duct is very hard, impact-resistant, and easy to install.2. Factory-made air ducts and on-site productionThe phenolic composite air duct can be installed and manufactured on site, or it can be manufactured in the factory and then transported to the construction site. Now more and more engineering companies prefer the latter, so what is the difference between the factory-made phenolic air duct and the on-site production of phenolic air duct? Time and labor costs, if these costs are saved in the factory, it only needs to be hoisted on site, and it also avoids the accumulation of waste disposal costs during the production process.In addition, there is almost no material loss in the production of air ducts in the factory, but in the case of on-site production by the engineering company without a cut-to-size board, the material loss is 15-20%, and the loss is even higher in the case of special-shaped parts! Calculated on 10,000 square meters of phenolic board, the loss is 1500-2000 square meters, and the loss cost is as high as 1/5. According to the calculation of 20 yuan/㎡, 10000*20=200,000 yuan, the loss is 30,000-40,000 yuan!This is not counting the cost of manual production and time. A skilled worker can make 40 square meters in 8 hours. Based on 10,000 square meters of phenolic boards, it takes 40 days for 10,000 square meters of phenolic boards to be produced by 6 people at the same time. It is better to buy the finished air duct directly in the factory than to buy the finished air duct directly in this way, which saves worry, time and effort.Factory-made cut-to-length boards with zero loss:It is easy for the engineer to make air ducts on-site to damage the protective film of the color steel plate and cause the iron sheet to rust. The gaps between the slices of the phenolic plate are not standardized by the workers, and it is easy to form a cold bridge, which will lead to heat loss, condensation, and moisture failure. Factory-made air ducts can avoid this situation, and the efficiency will be much higher!Duct flange:The air ducts are all controlled by machines from slicing, bending and forming, gluing, etc., and the air ducts are all pressed by standard production. The flange parts are made of PVC raw materials, which have good solid resistance and oxidation resistance. The quality of the flange is directly related to the overall firmness and service life of the pipe. The raw material PVC has strong toughness. Calculated according to the length of the 1.2-meter air duct, they can make up to 5 sections of air duct and 6 meters at the same time without deformation. , Greatly improve the work efficiency of hoisting air duct!According to the air duct production specification, rivets are required at the flange of the air outlet and the color steel plate, but sometimes in the on-site production, in order to meet the construction schedule, some masters use self-tapping screws to fix them, while their factories use rivets and rivets Much tighter than self-tapping screws.PS: Due to the standard production process and high production efficiency of the air duct in the factory, it saves a lot of purchasing and production costs, so it has been favored by many engineering companies in recent years! Although off-site production and installation may not be flexible enough, compared to the above-mentioned advantages of factory production, the disadvantages outweigh the advantages.

How To Make Sure The Clean Room Work Successfully
Ensure the purification of materials entering the clean roomMaterials entering the clean room shall be cleaned and purified before being transported into the clean room, so as to reduce the amount of dust generated by materials in the clean room. Small items entering the clean room generally enter through the transfer window between the clean room and the outer corridor or between the clean rooms (adjacent rooms with different cleanliness levels).Ensure that the air entering the clean room is cleanDuring the operation of the purification air conditioning system, the air filters at all levels used must be intact without damage or leakage. In order to prevent the air supply system from bringing dust particles that should not enter the room into the room, it is necessary to regularly check the leakage of the primary, medium and end air filters used in the system.Ensure the air supply volume of the purification air conditioning systemTo ensure the air supply volume of the air conditioning system is to ensure the number of air changes in the clean room to meet the needs of indoor air distribution. During the normal operation of the purification air conditioning system, the air supply volume of the system should be measured regularly. The measuring points can be selected at the inlet (outlet) of the air supply fan and the air supply outlet. Because the air supply volume of the system is comprehensively considered in terms of energy consumption, indoor air distribution and other aspects. If the air supply volume of the system is too low, the air flow velocity at the air supply outlet in the clean room will be reduced, thus damaging the indoor air flow organization form, making the indoor polluted air unable to be discharged, and failing to meet the indoor cleanliness level required.Ensure the positive and static pressure in the clean room as required.During the operation of a clean room, it is generally required to maintain a certain positive and static pressure difference between the clean room and the adjacent room and corridor (including the outer corridor), that is, the static pressure value of the clean room is higher than that of the adjacent room (rooms with different cleanliness levels) and corridor, so as to avoid pollution caused by the air outside the clean room with high dust concentration such as the adjacent room and corridor. Therefore, during the operation of the clean room and purification air conditioning system, attention should be paid to the regular inspection, maintenance, adjustment and repair of the residual pressure valve in the system, as well as the pressure sensor, transmitter, regulator and actuator, so as to keep them in normal operation and maintain the required positive and static pressure in the room Suzhou Pharma Machinery Co.,Ltd.2023/03/15David

Biosafety Cabinet, Ultra-Clean Workbench, Fume Hood Are You Using It Right?
~Suzhou Pharma Small Class~ At present, the importance of laboratory biosafety has been paid more and more attention. Among them, the most important measures to ensure the biosafety of the laboratory are the use of biosafety cabinets, ultra-clean workbenches, fume hoods and other equipment. However, laboratory staff are not very clear about their performance, selection, operation and disadvantages, and sometimes may confuse biosafety cabinets, ultra-clean workbenches and fume hoods. In fact, there are essential differences among the three. 1. Different definitionsBiosafety cabinet (BSC): is a box-type air purification negative pressure safety device to prevent infectious experimental materials from polluting or infecting the laboratory or experimental operators in the process of experimental operation. It is used to protect staff, laboratory environment and experimental products, and is the most basic safety protection equipment in the biosafety protection barrier. It can be divided into 1-3 levels.Fume hood: is also called fume hood. It is used to discharge toxic and harmful gases (toxic smoke or corrosive chemical gases) during the experimental operation to the outside to protect laboratory personnel from toxic chemical gases, and also to prevent powder inhalation hazards.Ultra-clean worktable: It is designed to protect the experimental objects and materials operated in the worktable from pollution, and does not protect the staff and laboratory. 2. Different working principlesThe working principle of the biosafety cabinet is to pump the air in the cabinet outward to keep the negative pressure in the cabinet and protect the staff through the vertical air flow; The outside air enters the safety cabinet after being filtered by HEPA filter to avoid contamination of the treated sample; The air in the cabinet also needs to be filtered by HEPA filter before being discharged into the atmosphere to protect the environment. At the same time, the external exhaust flow is also purified to prevent environmental pollution.The working principle of the ultra-clean worktable is to blow the air outside the cabinet inward to keep the cabinet in a positive pressure state, and the air flow inside the cabinet is blown from top to bottom (also horizontal flow) to protect the experimental materials; The outside air enters the ultra-clean workbench after being filtered by the high-efficiency air filter, forming a continuous dust-free and sterile ultra-clean air laminar flow (more than 0.3 is removed μ M dust, fungi and bacterial spores). Ensure that the experimental object is not contaminated during operation.The working principle of the fume hood: it is mainly to pump the air in the cabinet outward (without HEPA filter) to maintain the negative pressure in the cabinet, so that some toxic smoke and chemical gases in the experiment can be discharged in time, thus protecting the laboratory personnel and the environment. 3. Different protection objectsThe biological safety cabinet protects the laboratory and experimental operators.The fume hood protects the laboratory and experimental operators, and does not protect the experimental objects.The protection object of the ultra-clean workbench is the experimental object, and the operator is not protected. 4. The pressure in the cabinet is differentBiosafety cabinet: negative pressure.Ultra-clean workbench: positive pressure.Ventilation cabinet: negative pressure. 5. The air flow direction in the cabinet is differentBiosafety cabinet: from the outside to the inside, from the bottom to the top.Ultra-clean workbench: blow from inside to outside and from top to bottom (also horizontal flow).Ventilation cabinet: from the outside to the inside, from the bottom to the top. 6. Different disadvantagesUltra-clean worktable: protect samples, not people and laboratories. Once microbial samples are placed in the working area, laminar air will blow the air with microbial media to the front desk staff and laboratories, causing danger.Fume hood: It can not effectively remove microbial media. Some microbial samples placed in the fume hood may spread outside the fume hood and pollute the laboratory environment. Suzhou Pharma Machinery Co.,Ltd.2023/03/14Alice

Why Use Isolation Technology
Sterile isolator is composed of sterilization experimental chamber, two chambers of transfer chamber and vaporized hydrogen peroxide sterilizer, The transfer cabin sterilizes the samples (with packaging containers), inspection tools, culture media and buffer solution (sterilizes surface microorganisms with vaporized hydrogen peroxide gas),Sterility inspection (or microbial limit inspection) shall be carried out after entering the experimental chamber through RTP sterile transmission. The isolator adopts a hard cabin (or soft and strong) body structure. The interior material of the cabin is 316 stainless steel or non-toxic PVC, and the exterior material of the cabin is stainless steel 304 or non-toxic PVC. The cabin cleanliness meets the requirements of GMP Class A. The control system can perform automatic control operation and operation detection.The transfer of internal materials is carried out through the gloves provided by the isolator (gloves need to be regularly tested for leakage, pressure attenuation method). After sterilization, internal purification shall be carried out through the high efficiency filter H14 at the inlet and outlet, so as to maintain the Class A laminar flow (or turbulent flow) inside the cabin. The bacteria collecting instrument is integrated in the experimental cabin for drug sterility inspection and microbial limit inspection. After the inspection, the isolator is sent out through the outer door. Why use isolation technology Compared with the final sterilization products, there are more variables in the sterile operation process of non-final sterilization products.Every error in the operation process may cause product pollution.Some manual or mechanical operations have a great risk of contamination during aseptic operation.The need to protect products and operators. Operating steps of Sterile isolatorStep 1: Entry of test articles and inspection toolsStep 2: Preparation before sterilizationStep 3: dehumidification - regulation - sterilization - ventilation and residue removalStep 4: Experimental operation Suzhou Pharma Machinery Co.,Ltd.2023/03/13Spencer

How To Solve The Large Difference In The Weight Of Pressed Tablets(1)
Many customers will encounter the problem of large difference in the weight of pressed tablets during use. Here we will analyze the causes and solutions of the whole problem.1. The particle size distribution is uneven, and the particle flow rate is different during tablet pressing, resulting in uneven particle size filling into the middle mold hole. If the amount of coarse particles is large, the piece is light, and if the amount of fine particles is large, the piece is heavy.Solution: The particles should be mixed evenly, or the whole particles should be re-grained to ensure uniform particle size.2. If there is fine powder adhering to the punch, the difference in sheet weight may be large.Solution: At this time, the down-punch rotation is not flexible, so it is necessary to check in time, remove the die, and clean the down-punch and middle die holes.3. The particle flow is not good, and the amount of particles flowing into the middle mold hole is more or less, resulting in excessive difference in sheet weight and exceeding the limit.Solution: It is necessary to re-granulate or add appropriate flow aids, such as micro-powder silica gel, to improve particle fluidity.4. Particle layering.Solution: Solve particle layering and reduce particle size difference.5. For smaller tablets, choose materials with larger particles.Solution: select particles of appropriate size.6. The feeding hopper is blocked, which often occurs in drugs with strong viscosity or moisture absorption.Solution: dredge the feeding hopper, keep the tablet pressing environment dry, and add flow aids appropriately.

How Should Different Laboratories Correctly Select Biosafety Cabinets?
~Suzhou Pharma Small Class~ 1. When the biosafety level of the laboratory is Grade I or Grade II, the operation may produce microbial aerosol or spill, the Grade I biosafety cabinet can be used;2. When the biosafety level of the laboratory is Class II and infectious materials are handled, the Class II biosafety cabinet with partial or full ventilation shall be used; If the laboratory involves the treatment of chemical carcinogens, radioactive substances and volatile solvents, it can only use Class II-B full exhaust (B2) biosafety cabinet.3. When the biosafety level of the laboratory is Grade III, Grade II or Grade III biosafety cabinet shall be used; For all operations involving infectious materials, the fully ventilated Class II-B (B2) or Class III biosafety cabinet shall be used.4. When the biosafety level of the laboratory is Grade IV, the Grade III full-exhaust biosafety cabinet shall be used. When personnel wear positive pressure protective clothing, they can use Class II-B biosafety cabinet.The secondary biosafety cabinet can be divided into four levels according to the inlet air velocity, exhaust mode and circulation mode: A1, A2, B1 and B2. The specific differences are as follows:The minimum or average measured air velocity of the front window of A1 type safety cabinet shall be at least 0.38m/s. There is no internal circulation air flow, and 100% of the gas is filtered out through the exhaust port.The minimum or average measured air velocity of the front window of A2 type safety cabinet shall be at least 0.5m/s. 70% of the gas is recycled to the working area through HEPA filter, and 30% of the gas is filtered and discharged through the exhaust port.The minimum or average measured air velocity of the front window of the B1 type safety cabinet shall be at least 0.5m/s. 70% of the gas is discharged through the HEPA filter at the exhaust port, and 30% of the gas is recycled to the working area through the HEPA filter at the air supply port.The minimum or average measured air velocity of the front window of the B2 type safety cabinet shall be at least 0.5m/s. It is a 100% full-discharge safety cabinet without internal circulating air flow, which can provide biological and chemical safety control at the same time, and can operate microbial experiments with volatile chemicals and volatile nuclear radiation as additives. In addition: 1. HEPA filter can not effectively filter and remove chemical gases. If chemical gases are released in biological test, biological safety cabinet equipped with external discharge pipe must be used. 2. If cytotoxic is involved in the test, the cytotoxic biosafety cabinet must be used. summaryThe biosafety cabinet is a negative pressure purification workbench. The correct selection and use of the biosafety cabinet can really protect the staff and laboratory environment; The ultra-clean worktable is only a clean worktable that protects the operating objects and does not protect the staff and laboratory environment; The fume hood may pollute the laboratory environment when the operating samples contain microorganisms in order to discharge the harmful gases during the experimental operation to the outside. The fume hood and ultra-clean worktable are not biosafety cabinets and cannot be used in the experiment or production process involving microbial materials. In the scientific research, teaching, clinical inspection and production of microbiology and biomedicine, we should learn to correctly select and use biosafety cabinets, ultra-clean workbenches and fume hoods.

Clean Room Standards
Clean room test criteriaTo prove that the clean room works satisfactorily, it must be proved that it meets the requirements of the following criteria:1. The air supply volume of the clean room is sufficient to dilute or eliminate indoor pollution.2. The air in the clean room flows from the clean area to the area with low cleanliness,the flow of polluted air reaches the minimum, and the flow direction of air at the entrance and in the indoor building is correct.3. The air supply in the clean room will not significantly increase indoor pollution.4. The movement state of indoor air can ensure that there is no high concentration gathering area in the secret room.If the clean room meets the requirements of these criteria, its particle concentration or microbial concentration (if necessary) can be measured to determine that it meets the specified clean room standards. Clean room test:1. Supply air volume and exhaust air volume: if it is a turbulent clean room, it is necessary to measure its supply air volume and exhaust air volume. If it is a one-way flow clean room, its wind speed shall be measured.2. Air flow control between zones: in order to prove that the air flow direction between zones is correct, that is, from the clean zone to the area with poor cleanliness, it is necessary to detect: (1) the pressure difference between zones is correct; (2) The air flow direction at the door or at the opening of the wall and floor is correct, that is, from the clean area to the area with poor cleanliness.3. Filter leakage detection: the high-efficiency filter and its outer frame shall be inspected to ensure that the suspended pollutants will not pass through: (1) the damaged filter; (2) The gap between the filter and its outer frame; (3) Other parts of the filter device.4. Isolation and leak detection: This test is to prove that suspended pollutants do not penetrate the building materials into the clean room.5. Indoor air flow control: The type of air flow control test depends on the air flow mode of the clean room - turbulent flow or one-way flow. If the air flow in the clean room is turbulent, it must be verified that there is no area with insufficient air flow in the room. If it is a one-way flow clean room, it must be verified that the wind speed and direction of the whole room meet the design requirements.6. Suspended particle concentration and microbial concentration: if the above tests meet the requirements, the particle concentration and microbial concentration (if necessary) shall be measured finally to verify that they meet the technical conditions of the cleaning room design.7. Other tests: In addition to the above pollution control tests, sometimes one or more of the following tests must be carried out: Temperature,Relative humidity,Indoor heating and cooling capacity, Noise value, Light intensity, Vibration value Suzhou Pharma Machinery Co.,Ltd.2023/03/06Spencer

What Goes Into Constructing a Clean Room?
What goes into constructing a clean room?Constructing a clean room is a complex process that requires professional design and construction personnel. The proportion of various parameters in the clean room must be calculated and optimized to ensure it meets the required standards. The parameters include airflow direction, temperature, indoor layout, and auxiliary equipment installation. To make sure the clean room can meet all requirements, some room for transformation must be designed into the project, so it can be adjusted to fit new production processes without wasting time and money on unnecessary transformations in the future. The cost of constructing a clean room depends on the size of the space and the complexity of the design and materials needed. Proper planning is essential in order to minimize any unexpected costs that could arise from improper planning. Additionally, careful consideration must be given to the selection of qualified personnel with the appropriate experience and qualifications for the task.How much does it cost to construct a clean room?The cost of constructing a clean room depends on several factors, including the size of the room, the materials used, the complexity of the system, and the local labor and installation costs. Generally speaking, clean rooms can range from $50,000 to more than $1 million depending on the specifications and size. The most expensive part of constructing a clean room is often the labor required to install the systems and walls.The cost of constructing a clean room also depends on the level of cleanliness required. A standard clean room will require less equipment and thus cost less, while higher levels of cleanliness such as an ISO Class 7 or 8 require additional components and thus cost more. Additionally, the geographic location of the clean room can also affect the cost, as certain areas may require specialized materials and labor that could increase the total cost. Ultimately, a clean room construction project should be carefully planned and budgeted for in order to ensure that the desired level of cleanliness is achieved without overspending. By working closely with experts in the industry, you can develop a plan to construct a clean room that fits your needs and budget. Suzhou Pharma Machinery Co.,Ltd.2023/03/05Mia
