The u-bolt is named because it is shaped like a letter U. It has threads on both ends and can be combined with nuts, and is mainly used to fix tubular or sheet materials. It is used in a wide range of applications, such as linking mechanical parts of vehicles and ships, fixing pipes, bridges and railroad projects. Its application determines its working environment is harsh, often high temperature and high humidity environment, so rust and moisture is very important.
In addition to the material itself more use 304, 316, 316L and other stainless steel with good corrosion resistance, the surface coating is also a very important point
In the case of high corrosion resistance requirements, the surface treatment of U bolts is generally used without oxidizing ingredients of impregnating paint, such as epoxy oxy-urea alkyl or undenatured epoxy-based impregnating paint. Choose lacquers that do not contain volatile acids. Solvent-free lacquers are used for vibratory machinery as much as possible.
The use of melamine impregnating paint, should adjust the curing temperature and curing time, curing temperature to slightly higher than 130 ℃ (such as 135 ℃) and curing time more than 180min is appropriate, and it is necessary to strictly implement the process, especially in the high temperature and humidity season, rotary vibration screen because from the concept of rust prevention, paint factory samples in the rules of the paint drying (curing) time, not necessarily sufficient, the motor has Specific intrinsic shape.
Stainless steel screw surface corrosion prevention disposal is the use of various methods to apply maintenance layer on the metal surface, its role is to isolate the metal and corrosive environment, in order to stop the corrosion process, or reduce the corrosive media and metal surface touch, and to prevent or reduce the purpose of corrosion.
