Moisture-proof and moisture-proof measures for non-standard parts

The so-called fee standard room mainly refers to the fact that it does not follow the national standard specifications and does not have relevant parameter regulations. There are fastener companies that freely control their accessories. There are many types of non-standard parts and they are widely used, such as: furniture, electrical appliances, Engineering, construction and bridges need to use non-standard screws. In order for non-standard parts to keep up with moisture and moisture, we must take certain measures.

1. Use impregnating varnish that does not contain oxidizing ingredients, such as Epoxy-urethane-based or unmodified epoxy-based impregnating varnish. Use paint that does not contain volatile acids. Use solvent-free paint as much as possible for vibration machinery. (Guide: Four factors affecting the heat treatment of high-strength fasteners)

2. When using melamine dipping paint, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130°C (such as 135°C) and the curing time should be greater than 180min, and the process must be strictly implemented. Especially in the hot and humid seasons, because from the perspective of anti-rust concept, the paint drying (curing) time specified in the paint factory's sample is not necessarily sufficient, and the motor has a specific internal shape.

3. The anti-corrosion treatment of the surface of stainless steel screws refers to the use of various methods to apply a maintenance layer on the surface of the metal. Its function is to isolate the metal from the corrosive environment to inhibit the generation of the corrosion process, or to reduce the corrosive medium and metal Surface contact, and achieve the purpose of avoiding or reducing corrosion.
