How can U-shaped bolts be better to prevent moisture

In order to keep the U-shaped bolts well protected against moisture,

1. Use impregnating varnish that does not contain oxidizing ingredients, such as epoxy urethane or unmodified epoxy impregnating varnish. Use paint that does not contain volatile acids. Use solvent-free paint as much as possible for vibrating machinery.

2. When using melamine dipping varnish, 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 it is necessary to be strict Perform the process, especially in the high temperature and humid season, because from the perspective of anti-rust concept, the regular paint drying (curing) time in the sample of the paint factory is not necessarily sufficient, and the motor has a specific internal shape.

3. Anti-corrosion treatment on the surface of stainless steel screws refers to the use of various methods to apply a maintenance layer on the metal surface. Its function is to isolate the metal from the corrosive environment to prevent the occurrence of the corrosion process, or to reduce the corrosive medium and metal Touch the surface, and achieve the purpose of preventing or reducing corrosion.

At the same time, pay special attention to the skills of screw selection: (Guide: About the three materials of fasteners)

1. The mechanical properties of the screw material, especially the strength requirements. Some screws need higher strength, so choose the higher strength of the screw material itself.

2. The requirements of working conditions on the corrosion resistance of materials. Some screws are used in products with strong corrosion performance, which requires us to choose screw wires with strong corrosion resistance.

3. The working temperature requires the material's heat resistance (high temperature strength, oxidation resistance). Some screws are used in high temperature operation, which requires us to choose screw materials with high temperature resistance.

4. Requirements for material processing performance in terms of production technology. In terms of production technology, some screw wires are better to process, some are more difficult, and the hardness is harder in all aspects. This requires us to choose the appropriate hardness of the screw material, which is conducive to processing and production.

5. Other aspects, such as weight, price, and purchasing factors must be considered. The weight of the screw itself, price, purchase and other factors affect the choice of screw material, and proper consideration of these aspects can be a better choice of screw material.
