Abstract

The invention discloses a high-temperature anti-corrosion structure and process suitable for a severe chemical environment, belongs to the technical field of anti-corrosion processes, and can at least partially solve the problem that in the prior art, an anti-corrosion layer is short in service life under the chemical high-temperature environment of high temperature and a corrosive cavity. The high-temperature anti-corrosion structure suitable for the severe chemical environment comprises a base body and an anti-corrosion structure attached to the base body, the thickness of the anti-corrosion structure ranges from 7 mm to 12 mm, the anti-corrosion structure comprises an anti-corrosion layer, the anti-corrosion layer is attached to the surface of the base body, and the thickness of the anti-corrosion layer is at least 3 mm or above; the anti-abrasion layer is attached to the surface of the anti-corrosion layer, and the anti-abrasion layer is made of a ceramic material; the reinforcing piece is fixed to the surface of the base body and penetrates through the anti-corrosion layer and the anti-abrasion layer.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion technology, in particular to a high-temperature anti-corrosion structure and technology suitable for harsh chemical environments. Background technique [0002] The current anti-corrosion process usually uses various base resins, polyester resins, composite materials and other resins to stick on carbon steel. However, the temperature index of the operating equipment reaches 180 ℃ ~ 210 ℃, and the equipment exists in severe corrosion. The chemical environment causes the equipment to operate in a double harsh high-temperature chemical environment. The existing anti-corrosion process will easily lead to chemical corrosion and physical wear after long-term operation, resulting in the inability to operate for a long time, resulting in a short service life of the equipment. high cost of use. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a high-temperature ...
