If the iron screw is wet, or soaked in liquid. In or wet, etc., in this case, it will be very likely to rust. Meson screw. Therefore, in order to prevent the screws from rusting, we have to protect the screws from moisture and moisture. The introduction of meson screws, then how to deal with the moisture and humidity of the screws! The moisture-proof and moisture-proof methods of screws are as follows:

(1) Use solvent-free paint as far as possible for vibration machinery.

(2), choose impregnating paint that does not contain oxidizing components, such as epoxy-urethane (Epoxy-urethane)-based or unmodified epoxy (Epoxy-)-based impregnating paint.

(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 greater than 180min. The execution process, especially in the high temperature and humid season, because from the perspective of rust prevention, the paint drying (curing) time specified in the paint factory's samples is not necessarily sufficient, and the motor has a specific inner shape.

(4), use paint without volatile acid.

(5) Choose paint with good hydrolysis resistance.
