The main air duct connected to the purification of the operating room is the main air duct, and the air duct from the main air duct is the branch air duct. The raw material requirements of air duct in operation room purification are very strict. Today, I would like to share with us the requirements of raw materials for air duct in operation room purification project, hoping to help us.

　　As for the clean area in the purification project of the operating room, the purification work should be done well, the ventilation pipes and materials should be well fireproof, the sealing gasket material, structure and body should be flame retardant materials, and the fire resistance should be fire-resistant. The material quality and certification materials should be checked, and the clean engineering inspection should be observed. The fire prevention planning should be done to meet the fire resistance performance. The external insulation material of the air duct should be Non combustible or flame-retardant grade B1 and harmless to human body.

　　The processing raw materials used in the air duct are mainly pressure-resistant type of air duct, and the safe operation of the system is qualified. Under the effect of clean construction, the interface of the air duct should not be opened or cracked. The leakage detection of the air duct should be under the pressure of the system task. The visiting group is more scientific and meets the relevant specifications with the relevant purification equipment. The cleanliness specification of metal ventilation duct shall not have cross connection at the joint, the specification of raw materials shall not be less than the base, and the flange bolts of medium and low air ducts shall be the same as the specification. There was no light, crack, delamination and frost.

　　On the air duct surface of relevant glass, attention should be paid to the sand, and the wall surface should be flat, without edges and corners, and water seepage is not allowed. During the inspection of purification project in operating room, the surface of air duct and relevant regulations should not be affected. If the air duct is flat, observe whether the material is bonded and consolidated on the surface, and the surface protective fiber will not cause some damage to the human body. When inserting the interface, pay more attention to the adhesion at the joint. Aluminum foil and sealing tape can be used on the surface, and the width should not be less than 20cm. There is no relevant measures. The surface near the flange is flat, and the center is parallel. There is no deformation, bubble, aluminum foil and other damage
