Internal and external anti-corrosion of pneumatic valve
1, pneumatic valve body (
Including variable speed drive cabinet)
Both inside and outside, should first deoxidization blasting derusting, and strive to electrostatic spraying powder non-toxic epoxy resin, the thickness of 0.
More than 3 mm.
Oversize electrostatic spraying valve non-toxic epoxy resin are in trouble, should also be similar non-toxic epoxy paint brush, spraying.
2, inside the valve body and valve plate comprehensive anticorrosive parts requirements, on the one hand, soaking in the water will not rust, do not produce electrochemical corrosion between two metals;
Two aspects of smooth surface reduce water resistance.
3, the body of anticorrosive epoxy resin or paint the sanitary requirements, should have the corresponding authorities inspection report.
The physical properties of chemical also should comply with the relevant requirements.
