Laboratory furniture For biology, medicine, paint laboratories and clean rooms, thorough cleaning and disinfection are the first functions to be considered. This requires laboratory furniture to be easy to clean, disinfect and be able to keep clean for a long time. It is difficult for ordinary steel and wooden furniture to meet this cleanliness requirement. With the continuous development of the industry, the laboratory furniture industry continues to enter the market. How to choose is very important. For example: laboratory table: plate-type central platform Steel-wood unilateral experimental platform, all-steel central platform, water bucket platform, sky platform; Test bench panel: corrosion-resistant physical and chemical board countertop, Fume hood series: panel type through wind hood, steel-wood fume hood, new all-steel fume hood, floor-standing all-steel fume hood; cabinet series; reagent cabinet, utensil cabinet, gas cylinder cabinet, safety cabinet, locker, shoe cabinet; Reagent rack: plate type reagent rack, steel glass central reagent rack, waterproof socket, laboratory stool; Laboratory professional water bucket series: eyewash, emergency shower, laboratory special faucet, laboratory special Cork series; Laboratory ventilation system: atomic suction hood, universal suction hood; Office partition series: desks, office chairs, office partitions The perfect combination of stainless steel countertops and steel cabinets equipped with 25MM substrate plates, while taking into account the laboratory's requirements for cleanliness and load-bearing.
Clean room refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space, and the control of indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting, and static electricity In a certain range of needs, and given a specially designed room. That is to say, no matter how the external air conditions change, the room can maintain the original set requirements of cleanliness, temperature, humidity, and pressure. In order to correctly evaluate the construction quality of the project, the clean room cleanliness level (empty/static) should be measured. Test method and matters needing attention: 1. The dust particle counter has a particle size sensitivity of 0.3um and must be calibrated before testing. There should be no more than 3 indoor measurement personnel. The personnel must wear clean overalls and stand still or move slightly on the leeward side of the sampling point. 2. Set the measurement period to more than 2 minutes, and move as gently as possible when the measurement point changes. This is to minimize the impact of abnormal disturbance of the surrounding air caused by the walking of the tester or the handling of the test instrument. 3. Determine the minimum number of sampling points and take it according to the following formula. The principle is that the larger the area, the more measurement points. One-way laminar flow refers to the area of the air supply surface, and turbulent flow refers to the area of the room. When there is only one sampling point in the clean area, sampling should be done at least 3 times at this point. 4. The sampling port of the one-way flow clean room should be facing the direction of the air flow, and the sampling port of the turbulent flow clean room should be upward. The sampling speed should be as close as possible to the indoor airflow speed. 5. For a one-way flow (laminar flow) clean room, measure the number of particles debugged on the indoor working surface 0.6m away from the door when the door is open. clean room panel manufacturers、clean room doors manufacturers、hpl panels manufacturers
Air purification engineering refers to the removal of small particles, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, pressure, air velocity and airflow distribution, noise, vibration and lighting, Projects where static electricity is controlled within a certain range of requirements. The room designed by the purification project is very special. No matter how the outside air conditions change, the room still maintains the originally set cleanliness, temperature, humidity, and pressure. Air purification engineering can be divided into turbulent flow clean room and laminar flow clean room according to the principle; according to application, it can be divided into industrial purification engineering and biological purification engineering. The air purification project is a complete system, and there are related instructions in the clean room design and acceptance specifications. Air purification projects generally include clean room building decoration system, purification air conditioning system, water system, electric system, air system, etc. The air purification project is to control the temperature, humidity, illuminance, cleanliness, and static electricity phenomenon in the clean room, so as to meet the specific process requirements. The air purification project has obvious effects in improving product quality. According to reports in foreign literature, products manufactured in semiconductors in Class 10000 and Class 100 clean rooms have passed the pressure test. They are tested in Class 100 clean rooms and outside atmospheric environments. For transistor coating and diffusion, the performance distribution of products in a class 100 clean room is concentrated, and the peak appears in the place of higher performance. The performance of the product in the atmosphere is extremely dispersed and the performance is extremely unstable. It can be seen that (1) whether there is air purification or not, the product yield is very different. (2) In order to improve product quality, not only the environment in which the product is produced needs to be clean, but the production of its key raw materials and ingredients should also be carried out in a clean environment. Nothing can be absolute, nor can the role of air cleaning technology be absolute, nor can the effect of improving product quality be attributed to it. According to the analysis of foreign materials, for the semiconductor component sector, for example, the role of air cleaning technology in improving product quality accounts for about 20% of the entire production, while the automation of the production process accounts for 60%, and other factors account for 20%. Of course, after the problem of the production process has been solved, air purification is the main contradiction. For example, very large-scale integrated circuits can hardly be produced without a clean environment. Industries and sectors that require air purifi...
What is a purification project? There are many names for clean room projects in China. Some people like purification projects, and some people like purification projects. In fact, the meaning of both is the same. The purification project is also known as the Cleanroom project. Used in clean room engineering, purification engineering is used as a method to avoid copyright infringement, so it is also known as clean room design. Purification projects can also be called clean workshops, clean rooms, clean rooms, sterile rooms, etc., but they are generally called purification projects. The purification project is to eliminate particles, harmful air, bacteria and other pollutants in the air within a certain space, and control the indoor temperature, cleanliness, pressure, air velocity and air distribution, noise, vibration, lighting, and static electricity within a certain range. Engineering disciplines within the scope of demand. The room specially designed by the purification project has the ability to maintain the cleanliness, temperature, humidity and pressure of the originally set requirements regardless of the changes in the external air conditions. Then, let me introduce the composition of the purification project. The purification project consists of six systems: clean room ceiling system, air conditioning system, clean room partition wall, floor, and lighting fixtures. 1) Ceiling system: Including suspenders, beams, ceiling lattice beams, the materials are generally: color steel plate and dust-free board 2) Air conditioning system: including the host, air duct, filter system, FFU, etc. 3) Partition wall panels: including windows and doors, the material is color steel plate, but there are many kinds of color steel plate sandwiches. 4) Floor: Raised floor or anti-static PVC floor or epoxy resin floor. 5）Lighting appliances: use dust-free special lamps. What is the purification project? What is the classification of purification engineering? Purification projects are mainly divided into three categories: turbulent flow purification projects, composite purification projects and laminar flow purification projects. 1. Turbulent flow purification project The air enters the clean room from the air-conditioning box through the air duct and the air filter in the clean room, and passes through the partition wall panels or raised floor on both sides of the clean room. 2. Compound purification project The compound type is to conform or use the turbulent flow type and the laminar flow type together, which can provide local ultra-clean air. 3. Laminar flow purification project The laminar air flow moves into a uniform straight line, and the filter with 100% coverage of the empty area enters the room, and the air is returned by the raised floor or partition walls on both sides. This model is tried for use in environments where the clean room level needs to be set higher. Generally, the clean room level is CLass1~100
Now in many industrial occasions, air purification filter is one of the indispensable facilities, especially in the environment with high hygiene requirements such as hospitals. The application of air purification technology in medicine, in particular, creates a highly clean space for surgical operations, reduces the infection rate of the operation, and increases the success rate. The following editor will take everyone to understand the air purification technology. Air purification technology, as the name implies, air cleanliness refers to the degree of cleanliness in the air. Air purification technology refers to the use of physical methods to effectively remove polluting particles and other pollution in the air, so that the air within the space can maintain a certain level Cleanliness. The value of cleanliness is usually measured by the concentration of dust. If the concentration of dust is high, the cleanliness is low. Among them, the cleanliness in the clean operating room cannot be lower than 100,000; Air purification technology is usually classified into turbulent flow, horizontal laminar flow, and vertical laminar flow. At present, the most widely used operating room is the vertical laminar flow. The following is an introduction to what kind of operations different levels of clean operating rooms are suitable for: Class I special clean operating room can usually be used for joint replacement surgery, organ transplant surgery, brain surgery, surgery, ophthalmology and other operations; Class II standard clean operating room can be used in thoracic surgery, surgery, urology, orthopedics and other operations; Class III general clean surgery is generally used in general surgery, obstetrics and gynecology and other operations; The Ⅳ-grade standard clean operating room is suitable for anorectal surgery and other operations. Professional in the clean room industry for decades, welcome to inquire about clean room ceiling system, clean room doors and windows, clean room equipment, etc.
Clean room refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space, and the control of indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise, vibration, lighting, and static electricity In a certain range of needs, and given a specially designed room. That is to say, no matter how the external air conditions change, the room can maintain the original set requirements of cleanliness, temperature, humidity, and pressure. The main function of the clean room is to control the cleanliness, temperature and humidity of the atmosphere that the products (such as silicon chips, etc.) contact, so that the products can be produced and manufactured in a good environmental space. This space is called a clean room. One. Indicators of clean room. 1. The air supply in the clean room is sufficient to dilute or eliminate the pollution generated in the room. 2. The air in the clean room flows from the clean area to the area with poor cleanliness. The flow of contaminated air reaches the lowest level, and the air flows in the correct direction at the door and in the indoor building. 3. The air supply in the clean room will not significantly increase indoor pollution. 4. The movement state of the indoor air can ensure that there is no high concentration gathering area in the secret room. Two.Clean room testing. 1. Air supply and exhaust air volume: If it is a turbulent clean room, the air supply and exhaust air volume must be measured. If it is a one-way flow clean room, the wind speed must be measured. 2. Airflow control between each zone: In order to prove that the airflow movement direction between each zone is correct, that is, it flows from the clean area to the area with poor cleanliness, it is necessary to check: (1) The pressure difference in each section is correct; (2) The direction of air movement at the doorway or openings on the wall, floor, etc. is correct, that is, it flows from the clean area to the area with poor cleanliness. 3. Filter leak detection: The high-efficiency filter and its frame should be inspected to ensure that suspended pollutants will not pass through: (1) Damaged filter; (2) The gap between the filter and its outer frame; (3) Other parts of the filter device invade the room. 4. Isolation leak detection: This test is to prove that suspended pollutants do not penetrate the building materials into the clean room. 5. Indoor airflow control: The type of airflow control test depends on the airflow mode of the clean room-turbulent flow or unidirectional 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 entire room meet the design requirements. 6. Suspended particle concentration and microbial concentration: If the above tests meet the requirements, the particle concent...
