The water ring vacuum pump is evenly distributed on all surfaces of the equipment, while the latter only occurs locally. Such as pitting corrosion, crevice corrosion, intergranular corrosion, stress corrosion cracking, corrosion fatigue, hydrogen corrosion cracking, wear corrosion, delamination corrosion, etc.
It is one of the effective anti-corrosion measures to use polymer composite repair material to carry out the surface organic coating anti-corrosion. Surface adhesion protection can be widely used in repairing and pre protecting the parts of abrasion, cavitation and corrosion. It has good chemical resistance, excellent mechanical properties and adhesive properties. Compared with the traditional pressure vessel welding repair, it has the characteristics of simple construction, low cost, safety performance and good repair effect.
