China Nut is prone to rust when exposed in the air, so China Nut needs to be moisture-proof:

1. The choice of component insulation dipping varnish, such as epoxy resin or polyurethane dipping varnish. Choose paint that does not contain volatile acids. The vibration machinery uses solvent-free paint.
2. For the use of China Nut melamine alkyd paint, the curing temperature and curing time should be adjusted. The curing temperature is slightly higher than 130 degrees Celsius and the curing time is greater than 180 minutes. It is appropriate to strictly implement the process, especially in the hot and humid season. From the perspective of the concept of rust, Bolt Factory’s regular drying time is not necessarily abundant, and cars have a specific internal shape.
3. China Nut surface corrosion treatment refers to the use of various methods to maintain the metal surface. The function is to isolate the metal from the corrosive environment to inhibit the corrosion process, reduce the contact between corrosive media and the metal surface, and achieve the purpose of preventing or slowing down corrosion.

Pay special attention to the selection of screw material:

1. The mechanical properties and strength requirements of the screw material are strong. Some screws need a relatively high strength, and then choose the higher the strength of the screw material itself.
2. The corrosion resistance of materials in working conditions is required. Some screws of the standard network are used for the above-mentioned products with strong corrosion. This requires us to choose the corrosion resistance of strong spiral steel wires.
3. The material's heat resistance and working temperature requirements. In some cases where China Nut is used for high temperature operation, it is necessary to select the high temperature performance of the screw material.
4. Performance requirements in the production process of material processing. Some China Nut needs to deal with the difficulties of thread and hardness in the production process, so it is necessary to select the appropriate screw material hardness, which is beneficial to processing and production.
5. China Nut's own weight, price, purchase and other factors affect the selection of screw materials. It is a better choice to properly consider materials in these fields.
