How much do you know about the maintenance of Dongguan clean room?
1. Therefore, the following aspects of workshop hygiene should be paid attention to: 1) Vacuum cleaner It is recommended to use a clean vacuum cleaner in the purification workshop.
Ordinary vacuum cleaners in dust-free workshops should not be used or used as little as possible, because the dust content of the gas blown out by the vacuum cleaner is quite large, which will not only help the workshop environment, but also cause greater pollution. Perform a thorough sanitation of all places and equipment in the workshop.
2) Cleaning and tools In general, the mop on the floor of the workshop can not be used to completely remove the dust, because the mop material is not easy to dust, and the area of the mop is relatively large, it is not easy to completely remove the dust. Use dust-free paper to wipe wallboards and equipment. Generally, they are scrubbed with alcohol or acetone. Once acetone and alcohol have evaporated, the dust-free cloth is not cleaned, and the dust remains in place. Therefore, we recommend scrubbing with towels and water one by one. The area of the towels should not be too large (usually once every 1 ~ 2m2). Towels should be cleaned frequently and the water should be changed frequently so that the dust in the workshop can be cleaned.
3) When the sanitation workshop workers clean up, they must be divided into pieces, sections, and machines. From top to bottom, from high level to low level, including ceilings and lamps, and finally clean the floor from inside to outside when cleaning. The water must be changed frequently, and the towels must be washed frequently.
4) Return air filter cleaning in the workshop. Return air filter cleaning is usually performed once or twice a week.
2. Precautions for entering and exiting the workshop and wearing clean clothes 1. Before entering the clean room, personnel and materials will not affect cleanliness if they are not adequately dusted.
2. So before entering the purification workshop, do the following.
1) Carry paper towels, dust-prone items, and mobile phones should not be brought into a clean room, or the mobile phone should be turned off and placed in a pocket. When entering the clean room, a lot of dust is generated during the use of the mobile phone, so the clean room is not allowed to take out the mobile phone from the pocket to answer the mobile phone call.
2) Wear dust-free clothing.
3. Blow shower: Each employee must raise his arms to rotate during the shower, so as to help clean the dust outside the clean clothes.
3. Cleanliness testing 1) The cleanliness of dust-free workshops should be checked regularly. Generally, it should be tested once in March to June. (Conditional customers can test once a week with their own equipment). The principle is to prevent dust from entering the dust-free workshop, to prevent dust from being generated, and to prevent dust from remaining. For different management objects, the basic principles and management content are different.
2) Maintain the efficiency of the high-efficiency filter (regularly replace the filter), prevent the secondary flying of dust, and maintain the positive pressure in the workshop.
From the perspective of maintenance management, as the dust collection increases, the system resistance increases, and the filtration efficiency decreases. At this time, the indoor positive pressure and cleanliness are difficult to guarantee.
Once the positive pressure value of the clean room is reduced, the positive pressure value of the adjacent room will be greater than that of the clean room. At this time, dust will enter a lot and affect the cleanliness.
When employees walk into the workshop, they hope not to go too fast. Walking at a high speed will cause the second flying of the ground dust, which will greatly affect the cleanliness of the workshop.
When the employee walks in the workshop, the swing of the two arms should not be too large. If the swing of the two arms is too large, the dust in the dust-free clothing will be shaken out, because the dust-free clothing is relatively dust-free, not dust-free. . So everyone should pay attention to every little detail. In the workshop, when the cart is used to transport the goods, the speed of the goods should not be too fast, because the ground is relatively smooth, to avoid the large inertia of the car, the brake can not stop, and it will hit people or walls.
1. When walking in the workshop, try not to drag your feet on the spot, so as not to rub the ground and reduce the dust source.
