Clean room application
Clean room is a basic supporting industry with a very wide range of application industries. It is currently used in electronic information semiconductor optoelectronics precision It is used in many industries such as manufacturing, medicine, health, bioengineering, cosmetics, aerospace, aviation, automobile spraying, etc., and the levels vary greatly according to the precision and dust-free requirements of the industry.
At present, the highest level is undoubtedly the aerospace aviation warehouse, which basically belongs to the special field and has a relatively small area.
In addition, biochemical laboratories and high-precision nanomaterial production workshops have higher requirements. The development of IoT chips will be a major direction of future demand.
With the development of electronic components in the direction of miniaturization, LCD panels have been upgraded to the eighth generation. The industry demand is very huge.
． The studio should be short and flat, with an area of only about 1 meter high. The interior decoration should be flat and smooth, without unevenness or edges. The walls and roof should be made of impermeable material to facilitate scrubbing and sterilization
. The indoor lighting area is large and indoor conditions should be visible from the outside.
． In order to ensure the cleanliness of the sterile room, a buffer corridor needs to be set up around the sterile room. A buffer room should be set up next to the corridor. Its area can be smaller than the sterile room.
． The buffer corridors and buffer rooms of the sterile room are equipped with fluorescent lamps and ultraviolet lamps for sterilizing air. The sterilizing ultraviolet lamps are preferably meters away from the workbench, and their power switches should be located outdoors.
． The entrance and exit of the sterile room and the buffer room should be equipped with sliding doors. The door should be flush with the window. The door gap should be sealed tightly. The two doors should be staggered to avoid contamination caused by air convection
Requirements for sterile rooms
() The sterile room should be maintained Store only necessary inspection equipment in a clean and tidy room, such as alcohol lamps, alcohol cotton, matches, tweezers, inoculation needles, inoculation loops, glass pencils, etc. &;Do not place items unrelated to the inspection
() Indoor inspection equipment, stools, tables, etc. should be kept in fixed positions and should not be moved casually.
() Every week, wipe the workbench, windows, tables, chairs and floors with % carbolic acid aqueous solution, then spray and disinfect the air with % carbolic acid aqueous solution, and finally sterilize with UV light for half an hour
() Regularly check the sterility of indoor air for bacteria The number should be controlled below 1. When it is found that it does not meet the requirements, it should be thoroughly disinfected and sterilized immediately. /Method for determining the degree of sterility in a sterile room: Take ordinary broth agar plates and modified Martin medium plates (plate diameters are 1 cm), place them in each working position of the sterile room with the lid open and exposed for half an hour, then invert them for culture and measure the total number of bacteria. Incubate in a ℃ incubator for hours; to measure the number of molds, place it in a ℃ incubator and incubate for days. The total number of bacteria and molds shall not exceed 100%.
() Before sterilizing the sterile room, all items should be placed in the operating area (except for the items to be inspected), then turn on the ultraviolet lamp and when the sterilization time is up, turn off the ultraviolet lamp and wait for use
() Enter the sterile room Before entering, you must change into disinfected work clothes, work caps and work shoes in the buffer room.
() The operation should be carried out in strict accordance with the aseptic operation regulations. During the operation, talk less and make no noise to maintain the sterility of the environment.
