In recent years, as the use of clean rooms has been widely recognized by the industry, the application of clean rooms has become more and more extensive. For some products with high cleanliness requirements, the role of clean rooms is indispensable. However, while people lament the clean production environment that the clean room brings to the product, they gradually ignore the pollution of the clean room caused by external factors. This is quite a chronic suicide, which not only causes a waste of enterprise hardware costs, but also The product brings non-negligible pollution damage, which will greatly reduce the product superiority rate. This has caused most industry experts to pay attention to clean room pollution control. Where does this pollution come from? It is undoubtedly "people, machines, materials, methods, and environment". Among these factors, in addition to dust pollution, there is also a most basic "silicone-free" control. Based on many years of control experience, even if you do more Prevention, but the control of silicone oil is often not completely eliminated, why? Because of "people". People are the biggest source of pollution and the most difficult to control silicone oil pollution producer. The biggest source of silicone oil for the human body is cosmetics, especially female workers, who will inevitably apply smearing, especially in the cold winter, when dry skin will break down. Chips, or they are transferred to the material by hand, and the material must pass the test before it can enter the clean room. Some materials have already avoided silicone oil in the manufacturing process and materials, and they may be detected during retesting. Containing silicone oil, this is very wrong, so this is also the confusion of some companies in the selection of materials, they often want to figure out whether the material itself contains silicone oil, or the external contact is contaminated, it takes a lot of effort to repeat the verification, no doubt this is not Not advisable. At work, I often hear that some friends are not clear about the things that suppliers often use silicone oil. So how to eliminate this kind of dispute? The user can effectively control according to the following steps: 1. The user should inform the supplier in advance that there is a "silicone-free" control requirement; 2. Supplier control link: 1. The supplier shall ensure that the raw material itself does not contain silicone oil; 2. Supplier’s production processes, such as equipment, environment, and personnel operations, are all controlled without silicone oil; Third, the user material inflow inspection link: 1. Sampling of incoming materials to test the silicone oil item, namely FTIR test, generally requires 2 groups of tests, and each group needs to prepare 1-3 original samples of incoming materials. Test the first group first: directly rinse and then test and sample. If the result is OK, you do not need to perform the next group of tests; If the result is F...
With the continuous development of modern industry, the laboratory industry has ushered in a good opportunity for development. Competition in the laboratory furniture industry is also becoming increasingly fierce. The quality of laboratory furniture varies greatly. Although the development prospects are good, they are also facing huge challenges. Laboratory furniture tends to pay more attention to style when choosing, and the design styles are also diverse. And it needs to be unified with the overall style of the laboratory. To create a good laboratory environment to please the experimenters will also increase the efficiency of the experiment. In the choice of materials, laboratory furniture often pays more attention to the choice of materials, and will choose more environmentally friendly materials, which not only responds to the energy-saving and environmental protection of the current society, but is also more conducive to the use of laboratories. In terms of the quality of laboratory furniture, we must be more careful. Because some acid-base reagents are often used in the laboratory, they are all acid-base and corrosive. Therefore, our furniture needs to have certain chemical properties. The rigorous craftsmanship and high quality are the long-term survival of experimental furniture. Fundamentally; in terms of styles, there must be more variety, so as to meet the needs of different consumers. Due to the particularity of some laboratories, they will have some special requirements. Companies must be clear about the nature and characteristics of their own laboratories when purchasing, so that they can choose suitable and satisfactory laboratory furniture.

How to maintain constant temperature and humidity room and other laboratory equipment? Many friends do not know how to maintain the laboratory equipment in a constant temperature and humidity room. 1. The refrigeration systems such as condensers, copper pipes, evaporators, and compressors should be cleaned regularly, and dust should be removed in time. The refrigeration system is the core component of the machine, and it is the condenser that should be maintained on a monthly basis. Use a vacuum cleaner or a brush to suck and remove the dust attached to the condenser's heat sink or use high-pressure air to spray the dust. This can avoid the equipment. Overpressure, overload, etc. occur. 2. The over-temperature protector in the box should be checked regularly When the constant temperature and humidity room test chamber is running, the maximum setting value of over-temperature protection is increased by 20℃~30℃. When the temperature in the test chamber rises to the set point of over-temperature protection, the power supply of the heater stops, "OVERHEAT" The over-temperature warning light is on but the fan is still running. If it is running for a long time and is left unattended, please check the over-temperature protector before operation to see if it is properly set (the setting of the over-temperature protector is 120℃). 3.the wet ball gauze in the box should be replaced as appropriate When the surface of the wet ball gauze is not clean or hard, or the equipment is not used for a long time, the wet ball gauze needs to be checked or replaced before the next humidity test. The manufacturer recommends replacing it every three months (the gauze must be clean). This can prevent the device from showing 100% humidity, or the humidity cannot be increased or fluctuates greatly. Fourth, the cleaning and maintenance of the inside and outside of the constant temperature and humidity test box 1. The test chamber should be cleaned of internal impurities before manipulation 2. The power distribution room is cleaned at least once a year to prevent dust in the air from being adsorbed on the surface of the machine or on the condenser, evaporator and other accessories. 3. The exterior of the cabinet must also be cleaned more than once a year. When cleaning, wipe it with soapy water first, but do not use corrosive liquids. 5. Inspection and maintenance of humidifier in constant temperature and humidity test chamber The water storage tank in the humidifier should be replaced once a month to ensure that the water quality is clean. The humidified water must be purified water. Because the tap water has more impurities, it is easy to block the water pipe and affect the progress of the experiment. The humidification water tray should be cleaned once a month to ensure smooth water flow. Welcome inquiry laboratory table 、Fume hood 、Laboratory sink and Laboratory cabinets.
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
