How to deal with the covering layer of screw bolts?
The structure of the covering layer of screw bolts should be tight and small in pores.
The layer of screw bolts is evenly distributed and has a certain thickness.
The covering layer of screw bolts is separated from the base metal and has good adhesion.
Screw bolts should be treated with corrosion resistance, wear resistance with high hardness.
Screw bolts have strong corrosion resistance, high temperature resistance, and good rust resistance. However, they will also be rust if they are often exposed to harsh environments.
How to do moisture-proof measures for screw bolts?
If the screw bolts get wet, it is very likely to rust. Therefore, in order to prevent the screw bolts from rusting, we have to protect them from moisture.
Use solvent-free paint as far as possible for screw bolts used on the vibration machinery.
It is best to use impregnating varnishes that do not contain oxidizing components.
When using melamine dipping paint, the curing temperature and time should be adjusted. The temperature should be slightly higher than 130°C and the time should be greater than 180 minutes. The process must be strictly implemented, especially in the hot and humid season.
Use paint without volatile acid for screw bolts. Or, choose a paint with good hydrolysis resistance.
