Description
[technical field]
The application is a kind of priming paint more particularly to a kind of coating steel pipes surface and the bottom of chemical-resistance and mechanical performance
Paint.
[background technique]
Steel pipe is essential in life, but since steel pipe is chronically at the environment of dark humidity, steel pipe is caused to hold
Easily get rusty, thus will painting, but paint be easy to fall off, long term wear is split, and is easy to split under high temperature, or rotten
Erosion, so need painting repeatedly, and the ability painting that derust, derusting keep steel thinning, shorten steel products every time
Use the time.
In conclusion the priming paint for designing a chemical-resistance and mechanical performance is that those skilled in the art have to be solved ask
Topic.
[summary of the invention]
