Anti-pollution protection of stainless steel plates and air ducts in air purification projects Stainless steel plates cannot be stacked flat, and should be placed on a wooden support. When picking up plates, avoid sliding on the next plate to damage the passivation film on the surface of the plate. Lay the rubber sheet on the working platform as much as possible. When unfolding the pattern drawing line, do not use a sharp metal needle to draw auxiliary lines and punching holes on the surface of the sheet to avoid scratches; you can make a good template first, and then scribble on the surface of the stainless steel sheet. Material, stainless steel plate should be marked with a pencil, not with a metal needle. In the process of processing stainless steel plate air ducts, the following protective measures must be taken for the passive film on the surface of the stainless steel plate: remove the rust and sundries on the processing machinery and equipment to prevent the rust and oxides from corroding the stainless steel surface. When manual bite or hammering is required, a mallet and a copper hammer should be used; when measurement is required, a wooden square ruler, stainless steel measuring tools, etc. should be used, and carbon steel tools should not be used as much as possible. 2. Connection method Because of the high strength and good elasticity of stainless steel, only when the thickness of the plate is less than or equal to 1mm, bite connection or riveting can be used, and when the thickness is greater than 1mm, electric welding or non-melting electrode argon arc welding should be used. Before using gasoline and other solvents, the grease in the weld area should be cleaned; the welding material should match the base metal. When DC arc welding is used, the reverse pole method should be used for welding. During the welding process, generally coat both sides of the weld. The prepared paste can prevent the welding slag from adhering to the surface; after welding, use a stainless steel wire brush to remove the welding slag and spatter in the welding seam and its affected area. Rinse off with hot water. Zhongjing Global Purification can provide supporting services such as consultation, planning, design, construction, installation and transformation of purification projects and clean workshops. 3. Air purification engineering stainless steel air duct flange Stainless steel plate air ducts can be flangeless or flanged. When stainless steel flat steel flanges are used for stainless steel air ducts, the flange material specifications should meet the requirements in the table below. When the rectangular stainless steel air duct is connected with thin steel plate flanges, its production requirements are the same as those of ordinary thin steel plates. When the fastener material is carbon steel, its surface should be chrome-plated or galvanized. Handle.

Made of hot bending stainless steel flange, the stainless steel flat bar can be heated by heating equipment, the temperature should be controlled between 1100~1200°C, and the hot bending temperature should not be lower than 850°C. The flange after hot bending must be reheated to 1100~1200C, and then quickly cooled with water. When drilling the stainless steel plate, the high-speed steel drill bit should be used, and its top angle can be ground to 118°~122°. When the flange material of the stainless steel air duct is made of carbon steel, the material specification should comply with the relevant regulations, and surface treatment measures such as galvanizing and chrome plating should be taken, and stainless steel rivets should be used.
