Moisture-proof measures

If the iron screw gets wet, or if it gets soaked with liquid.Be in or be affected with damp wait, such word, can rust very likely.So,

In order to prevent the screws from rusting, we have to protect them from moisture and moisture.So how to handle the screw moisture-proof and moisture-proof!Screw moisture-proof and moisture-proof methods are as follows :

(1) try to use solvent-free paint for vibration machinery.

(2) it is best to choose epoxy-urethane or unmodified epoxy-based impregnating paints that do not contain oxidizing ingredients.

(3) the use of melamine alkyd varnish, should adjust the curing temperature and curing time and curing temperature slightly higher than 130 ℃ (135 ℃) and curing time is more than 180 min advisable, and must be strictly implemented process, especially in high temperature and wet season, spin vibration sieve because from the perspective of the concept of rust, paint factory samples of paint drying (curing) prescribed by the time, is not necessarily sufficient, motor have specific inner shape.

(4) use non-volatile acid paint.

(5) choose paint with good hydrolysis resistance

There are many types of screws, whether they are small screws for glasses or large screws for heavy electrical engineering.The precision of screw is usually 6g (grade 2, American specification "IFI" is 2A), and the raw screw used in construction is 1g.
