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
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...
