Introduction to the main methods of preventing sink rolls bearings from rusting In the use of sink rolls , we will find that the accessories are prone to rust. The most common one is the rust of the sink rolls bearings. Therefore, we must find ways to solve this problem when producing sink rolls. Today, I will introduce the prevention of sink rolls. The primary method of rusting in rolls bearings. First, choose corrosion-resistant materials: mainly non-ferrous metal alloys and stainless steel. Second, the metal surface prefabricated metal (alloy) or non-metallic coating: 1. Conversion coating: blackening (blue), phosphating, anodizing; 2. Surface alloying: nitriding, galvanizing, siliconizing, aluminizing, chroming, etc.; 3. Metal coating: electroplated metal, sprayed metal, hot dip plating, chemical plating, etc.; 4. Non-metallic covering: enamel, ceramic, paint, plastic, rubber, etc.; 5. Coating anti-rust materials: anti-rust water, cutting fluid, ...
