along with PPH storage tank The service life will inevitably be affected by the longer and longer service life of. Compared with the storage tank made of metal, PPH storage tank has good corrosion resistance during use, and good corrosion resistance can effectively extend the service life. Now let's introduce how to prevent corrosion of PPH storage tank in detail?

Physical anti-corrosion: during the processing, the PPH storage tank produced with proper oily film-forming agent in the network will have a much better anti-corrosion effect in use. For example, the use of some oil-bearing lead pigments can make the anti-corrosion coating more compact, which will also reduce the saturation effect of substances on equipment. Phosphate pigment is an alkaline acid salt, which is not easy to dissolve after hydrolysis and can well block the pinholes in the paint. However, the oxide produced by pigments such as iron powder or scaly mica powder will reduce the permeability of the anti-corrosion coating when filling, so the PPH tank can play a very good anti-corrosion role on the physical level.

Chemical anti-corrosion: when harmful acidic and alkaline substances penetrate into the anti-corrosion coating, they can be neutralized and then converted into harmless substances. In terms of anti-corrosion, amphoteric compounds such as zinc oxide can be well used to neutralize acidic or alkaline substances to achieve anti-corrosion effect. In addition, some alkaline substances can be adsorbed on the steel surface and then kept in alkaline state, so that the steel of PPH storage tank is not easy to rust in alkaline environment.

Electrochemical corrosion prevention: the principle of this method is that water penetrates the pinholes of the coating. When oxygen passes through the anti-corrosion coating, it will form anti-corrosion ions with anti-corrosion equipment dispersed in the anti-corrosion coating of PPH storage tank.

Pure polyethylene is used as raw material and special rotational molding process is adopted for integrated molding. It has the advantages of no welding, no leakage, light weight, aging resistance, impact resistance, corrosion resistance, long service life, etc. The advantages of integration, corrosion resistance and long service life are particularly prominent. PPH mixing tank It can store and react most inorganic acids, alkalis, salt solutions and most organic solvents, and can partially replace stainless steel, titanium, nickel, alloy steel and other materials. This product complies with the regulations on the storage and transportation of dangerous goods, and is an ideal storage container for storing corrosive solutions and reactive chemical industrial cleaning fluids. This product is in line with China's health standards and can replace stainless steel containers to transport food solutions.
