Internal and external anti-corrosion of pneumatic valve
A, pneumatic valve body (
Including variable speed drive cabinet)
Inside and outside, should first deoxidization blasting derusting, and strive to electrostatic spraying powder non-toxic epoxy resin, 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.
Second, pneumatic valve's body within a set each require comprehensive anti-corrosion valve plate, on the one hand, soaking in the water will not rust, do not produce electrochemical corrosion between two metals;
On the other hand, surface smooth and reduce water resistance.
The body of the three, pneumatic valve 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.
