With the deepening of the study, the requirements for the environment are getting higher and higher. How to make the indoor environment satisfactory is the condition for the study. The air purification project probably happened and strong.
In a fixed space range, the moisture, harmful substances and bacteria contained in the air can be reasonably regulated by certain means. Purification engineering is such an operation, by changing the air pressure, so that the indoor environment to a certain standard, and then can be satisfied with production and operation.
Control of tightness requirements in clean workshop. Between rooms with different cleanliness levels, the rooms with higher cleanliness levels and the adjacent rooms with lower cleanliness levels should maintain a positive static pressure difference, and accept the short-term pressure difference when the equipment starts. Therefore, it is necessary to adopt a close technical approach to meticulous operation: the ground of the clean room is often required to wash, and double stainless steel cover is selected to drain the floor leakage. In construction, besides carefully locating the elevation and drainage inclination to avoid pipeline blockage, it is also necessary to pay attention to ensuring the surface accuracy of the floor drain itself, the tightness and brightness of the ground drain and the ground joint, so as to meet the requirements of cleanliness and sealing. The floor of the clean workshop should be flat, wear-resistant, easy to dust cleaning, not easy to accumulate static electricity, to ensure that the surface and the base layer are bonded solid, not cracked, and comfortable.
In order to accept the rugged deformation and cracking of the suspended roof under the change of static pressure difference and pressure when the equipment starts up, attention should be paid to enhancing the integrity of the skeleton during construction, so that the deformation and sealing of the suspended roof can be properly solved and the expected air tightness can be achieved; lamps, tuyeres, functional joints, observation windows, fire box, distribution cabinets, etc. The sealing and crack-proof methods around the holes and at the junctions of different materials are strictly followed to ensure the air tightness of the whole clean room, and the doors and windows should have outstanding air tightness. Structures and construction crevices on the walls, roofs, floors and floors of clean workshops should be tightly sealed. Clean and non-clean areas of the workshop generally have a expansion joint, in the joint is generally filled with polystyrene foam board, stainless steel cover plate is installed outdoors, indoor pressure color profiled steel plate, expansion screws fixed. The outer edge of the cover is sealed with sealant.
