Problems solved by technology

But no matter what kind of corrosion-resistant material is used, it will increase the electrostatic accumulation on the surface of the explosion-proof material and reduce the hardness of the material. Once the anti-corrosion coating falls off, it will also block the oil pipeline

Description

Technical field [0001] The present invention relates to the technical field of alloy explosion-proof materials resistant to alkali-resistant, and more particularly to an alloy explosion-proof material for acid and alkali-resistant corrosion. Background technique [0002] In the field of storage and transportation in flammable liquid or gas, people will be careful; however, despite this, due to some unpredictable, sudden reasons, chemical plants, refiners, gas stations, cars, oil vehicles, oil depots Incidents caused by accidents, causing an explosion, causing huge losses to the country and people's property. In view of the needs of the market, countries around the world have developed various inhibitor, such as polyurethane foams, paper materials, film materials, etc., but these materials are poor chemical stability in petroleum products, very easy to crack breakage, causing liquid pollution, not Suitable for long periods of use. The combustion of the petroleum products exploded,...
