Iron screws are easy to rust in a humid environment. In order to prevent the screws from rusting, the screws need to be moisture-proof and moisture-proof.
The moisture-proof and moisture-proof methods of screws are as follows:
(1) Vibration machinery, try to use solvent-free paint.
(2) It is best to use impregnating paints that do not contain oxidative components, such as epoxy-urethane (Epoxy-urethane)-based or unmodified epoxy-based (Epoxy-)-based impregnating paints.
(3) When using melamine alkyd impregnating 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 longer than 180min, and the process must be strictly implemented, especially In the hot and humid season, the drying (curing) time of the paint in the paint factory's samples is not necessarily sufficient from the perspective of rust prevention, and the motor has a specific inner shape.
(4), use paint without volatile acid.
(5) Choose paint with good hydrolysis resistance.
