Measures for moisture-proof and moisture-proof of screws

If the iron screw is wet or soaked in liquid. If it is damp or damp, it is very likely to rust. Meson screw. So, in order to prevent screws from rusting, we need to moisture-proof and moisture-proof the the screws. Introduction to meson screws, how to treat screws with moisture and moisture resistance! The moisture-proof and moisture-proof methods for screws are as follows:
(1) Vibration machinery should use solvent free paint as much as possible.
(2) It is best to choose impregnating paint without oxidation components, such as epoxy urethane based or unmodified epoxy based impregnating paint.
(3) When using melamine acid impregnating paint, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130 ℃ (such as 135 ℃) and the curing time should be greater than 180 minutes. It is recommended to introduce meson screws and strictly follow the process, especially in high temperature and humid seasons. From the perspective of rust prevention, the drying (curing) time specified in the paint factory’s samples may not be sufficient, and the motor has a specific internal shape.
(4) Use paint that does not contain volatile acids.
(5) Choose a paint with good hydrolysis resistance.
