Static Electricity In Clean Room

Clean room is a specific working area that uses special building materials and professional equipment to reduce or eliminate viruses, bacteria and dust in the area to ensure the smooth progress of various production and experiments in the clean room. But the emergence of static electricity will destroy the use function of the clean room.

Static electricity is extremely harmful. When static electricity is generated in clean room, it will have a bad impact on equipment, production products or experimental projects. It can not only disrupt the normal operation of electronic instruments, but also damage electronic products and lose their original functions. If sparks are generated, light-sensitive materials will be exposed or scrapped. Once static electricity is generated in the material or equipment in the clean room, it will attract dust, which is difficult to clear, causing pollution and affecting the cleanliness of the clean room. The most serious hazard is that it will cause safety hazards. Clean rooms often have experimental materials, flammable and explosive materials, or hazardous chemical products. If sparks are generated due to static electricity and cause fires, it will cause both human and economic losses.

When the electric charge moves due to some reason, the balance of positive and negative electric charge in the object is destroyed, resulting in excess electric charge, so the object is charged. Because these electric charge are static and do not flow, they are also called static electricity. There are many reasons for static electricity, the most important of which is the friction of objects. Friction of objects, friction of materials, friction caused by human shoes and clothing, etc.

How should we deal with static electricity that very easy to generate? First, we must ensure that the main building of the clean room has anti-static function. We can use materials with good conductivity as the walls, ceilings and floors of the clean room to create an anti-static clean room. The floor should be made of conductive or anti-static PVC floor. The walls and ceilings should be made of sandwich panel made of aluminum honeycomb or rock wool color steel plate. And there should be good grounding. In addition to the anti-static properties of the materials in the clean room, the staff in the clean room should also pay attention to anti-static. We can set up an anti-static eliminator at the entrance of the clean room. We should also pay attention to the selection of clean room consumables. Gloves, masks, hats, work clothes, and shoes should all be selected with anti-static functions. Another very effective anti-static method is to ensure the humidity in the clean room. But be careful not to have adverse effects on the machines and equipment in the clean room.
