How the non-standard measures to deal with the three moisture moisture

The so-called non-standard parts mainly refers not in accordance with the national standard, not outside the parameters of the relevant provisions of fastener enterprises have the freedom to control their parts, non-standard parts of many different types of applications are very wide, such as: furniture, electrical appliances, engineering, construction and bridges need to use non-standard screws. In order for non-standard items to better moisture moisture, we have to take certain measures.

1, the selection does not contain the oxidizing component of the varnish, such as epoxy urethane (Epoxy-urethane) group or a modified epoxy (Epoxy-) based varnish. Using paint free of volatile acids. Try to mechanical vibration-free solvent paint.

2, the use of melamine alkyd varnish, should be adjusted to the curing temperature and curing time, curing temperature slightly higher than 130 ℃ (such as 135 ℃) and curing times greater than 180min appropriate, and must be strictly enforced Technology, especially in hot and humid season, vibration sieve because from the point of view of the concept of rust, paint samples of paint in a predetermined drying (curing) time, is not necessarily sufficient, the motor has a specific internal shape.

3,stainless steel screwThe appearance of corrosion is the use of a variety of ways to dispose of applying a protective layer on the metal surface, and its role is to isolate the metal and corrosive environments to suppress the corrosion process, or reduce the corrosive medium in contact with the metal surface, and avoid or reach mitigate corrosion purposes.
