Purification engineering is a basic supporting industry with a wide range of application industries. It is currently applied in many industries such as electronic information, semiconductors, optoelectronics, precision manufacturing, medicine and health, bioengineering, aerospace, automotive spraying, and so on. Dust-free requirements, the level difference is also large.
1 Choose materials with good airtightness and small deformation according to temperature changes; when the wall needs to add light steel keel and insulation materials, non-combustible materials or non-combustible materials should be used;
2 The inner wall and ceiling surface of the clean room should be smooth, bright, clean, without traces, avoid reflection and corrosion resistance, and be made into smooth shapes at the corners of the walls and floors. Light steel keels are used as partition walls, and measures to prevent collisions should be taken;
The floor of the clean room should be good and smooth as a whole, with wear resistance, corrosion resistance and impact resistance. In addition, it should have anti-static, easy to clean and dust removal functions;
4 When the light steel keel is used as a technical inspection space, the maintenance channel should be laid at the exit;
5 The exterior walls and windows of clean rooms and personnel clean rooms should have good air-tightness, and have the function of preventing air leakage and condensation;
6 Clean room doors and windows are simple, smooth, not easy to trap dust, and easy to clean; no threshold is set; and in order to prevent bacteria or doors and windows from deforming due to moisture, wooden products cannot be used to clean doors and windows in the area;
7 The windows of the clean room should face the room with high air cleanliness level, and the windows should be of sufficient size to facilitate the installation, maintenance and replacement of general equipment;
8. The inner walls of the doors and windows installed in the clean room should be smooth, and try not to use window sills. If there is a window sill, in order to prevent dust residue and facilitate cleaning, it is necessary to make the slope as much as possible;
9 The doors on both sides of the delivery box should be interlocked with good air tightness and easy cleaning;
10 The color of the clean room should be elegant, soft and harmonious. In addition, the light reflection coefficient of the decoration materials on each side of the room is 0.6-0.8 for the ceiling and wall, and 0.15-0.35 for the floor.
11 The wall and ceiling coating of the clean room should be flame-retardant, anti-crack, corrosion-resistant, wear-resistant, and have a smooth surface. It should absorb water and not degenerate during use, and it should have no mildew coating;
12 The plastering of walls and ceilings of clean rooms shall adopt advanced plastering standards, and the curing time shall be sufficient; materials that are deformed, cracked, moldy or crushed due to heat and humidity shall not be used. After plastering, the paint surface should be painted, and the paint should be flame-retardant, non-cracking, resistant to cleaning, smooth surface, not easy to absorb water, deterioration and mold.
