Printing and packaging dust-free workshop is within the scope of a certain space in the particles in the air, bacteria and other harmful air pollutants, and the indoor temperature, cleanliness, interior pressure, air velocity and air distribution, noise, vibration and lighting, static control within the scope of a certain demand, and the special design of the room.
Purification engineering principle of printing and packaging workshop:
Air flow primary purification air conditioning medium efficiency purification fan air supply pipeline efficient purification tuyres blowing into the room taking away dust bacteria and other particles return air shutter primary purification repeat the above process, you can achieve the purpose of purification.
Dust-free printing and packaging workshop structural materials:
1. The clean room wall and roof materials are generally made of polystyrene pod-core color steel plate with a thickness of 50mm and aluminum oxide profile specially used for purification. The door is purified and closed, and the window is fixed with aluminum alloy glass.
2. The floor is cleaned with epoxy self-leveling or advanced wear-resisting plastic.
3. The purification ventilation pipe of the printing and cleaning workshop is made of galvanized steel sheet, and the "PEF" flame retardant insulation board is used for insulation.  
Dust free workshop main installation equipment:
The clean workshop air inlet system shall be installed, the fresh air filter box, and the central purification air conditioning (the central purification air conditioning shall be divided into three filtration sections of primary effect/medium effect/high efficiency) shall have an efficient air supply outlet at the end. If necessary, it is also equipped with a purification booster box;
Clean workshop air return system should be installed, air return port, filter primary effect, medium effect return box. Enter the buffer zone before entering the dust-free purification workshop. The door of the buffer zone is installed with electronic interlock, and clean wardrobe and air freshener are placed in the dressing room.
People and goods into the purification workshop must pass through, air shower, cargo shower, transfer window mainly transfer small items; The vertical laminar flow worktable, laminar flow hood (FFU), clean shed (portable purification work shed) and self-purifier should be installed in the part of the clean purification workshop that reaches level 10-1000. For measuring cleanliness of clean room, laser dust particle counter;
Clean workshop to design observation Windows for easy access.
