Points for attention when using double and single side super clean worktable

Double and single-sided super clean working table is widely used in the scientific research and production departments that need local clean and sterile working environment, such as medicine and health, biopharmaceutical, food, medical science experiment, optics, electronics, sterile room experiment, sterile microorganism inspection, plant tissue culture and inoculation It is a one-way flow type air purification equipment that provides local dust-free and sterile working environment It can also be connected into an assembly line with the advantages of low noise and mobility It is a kind of air purification equipment which can provide local high cleanliness working environment with strong universality Its use has good effect on improving process conditions, improving product quality and increasing yield This paper mainly introduces the main points that should be paid attention to when using the double one side super clean table The power supply of the super clean platform mostly adopts three-phase four wire, including one zero wire, which is connected to the machine shell and should be firmly connected to the ground wire The other three wires are all phase wires and the working voltage is 380V There is a certain sequence in the three wire access circuit If the wire head is wrongly connected and the wind opportunity reverses, the sound is normal or slightly abnormal at this time, and there is no wind on the front of the super clean platform (you can use the alcohol lamp flame to observe the movement and stillness, but not to try for a long time) You should cut off the power supply in time, and only change the position of any two wire heads and then connect them, it can be solved If the three-phase line is only connected to two phases, or one of the three phases is in poor contact, the sound of the machine is very abnormal, and the power supply should be cut off immediately for careful maintenance, otherwise the motor will be burned These common sense should be explained to the staff at the beginning of using the super clean platform to avoid accidents and losses There is a common foam plastic sheet or non-woven fabric in the metal net cover for blocking the large particle dust It should be checked and disassembled and washed frequently, such as aging plastic foam and changing it in time In addition to the air inlet, if there is any air leakage hole, it shall be blocked tightly, such as pasting adhesive tape, plugging cotton, pasting glue paper, etc In the metal mesh cover on the front of the workbench is the super filter, which can also be replaced If the super filter is used for a long time, the dust particles are blocked, the wind speed is reduced, and the sterile operation cannot be guaranteed, it can be replaced with a new one The ultraviolet lamp can also be hoisted on the ultra clean worktable, but it should be installed outside the lighting lampshade, and the arrangement of the lighting lamps should be staggered, so as not to hinder the lighting when working If the ultraviolet lamp is installed in the lighting lampshade (glass plate), it is useless, because the ultraviolet ray cannot penetrate the glass, its lamp tube is quartz glass, not silicate glass The inoculation room should be simple as much as possible, and all articles that have no direct relationship with the work of the room should not be put in, so as to keep sterile The air in the inoculation room shall be isolated from the outside air, and the reserved ventilation channel shall be closed as much as possible The vent passage can be equipped with upper and lower air windows The area of the air windows should be slightly larger, and 4 layers of gauze should be covered for simple dust filtering After a day's work, the windows can be opened for full ventilation, and then sealed In short, it is clean and sterile, fresh air and suitable for work The gauze covering the ventilation window should be changed frequently However, the above measures are only ideal design schemes, which are not easy to achieve in an all-round way In fact, they are only strictly sterile operation procedures In the room with open doors and windows, there is a super clean platform protection, and the pollution rate of vaccination is still controllable at a level that can be tolerated in production Double single-sided super clean working table service life and air cleanliness In the temperate zone, the super clean platform can be used in the general laboratory However, in the tropical or subtropical zone, the super clean platform should be used in a better indoor area with double doors, where there is a lot of pollen or dust in the atmosphere Under no circumstances should the air inlet hood of the super clean platform face the open door or window to avoid affecting the service life of the filter Asepsis room should regularly use 70% alcohol or 0.5% phenol spray to dust and disinfect, use 2% new germnon wipe the table and utensils (70% alcohol can also), cooperate with ultraviolet sterilization lamp (15 minutes above each time) and so on disinfection and sterilization means, so that the asepsis room often maintains the aseptic shape The interior of the inoculation box shall also be equipped with ultraviolet lamp The lamp shall be turned on for more than 15 minutes before use for sterilization However, there are still bacteria in places where the lamp cannot reach When the UV lamp is turned on for a long time, it can stimulate the oxygen molecules in the air to associate with the ozone molecules This gas component has a strong bactericidal effect, and can have a bactericidal effect on the corner where the UV light does not directly hit Because ozone is harmful to health, the ultraviolet lamp should be turned off before entering the operation, and then it can enter in more than ten minutes.
