Compared with metal tanks, PPH tanks have better corrosion resistance during use and can store a wider range of materials during use. Today, let's take a look at how PPH storage tanks are protected against corrosion. PPH winding tank

1. Physical anti-corrosion: during processing, add appropriate oil film forming agent in the assembly net, so that the anti-corrosion effect of PPH storage tank in use will be better. For example, the use of some lead paint and oil can make the anti-corrosion coating more compact, which will also reduce the saturation of materials on the equipment. Phosphate pigments are alkaline salts, which are not easy to dissolve after hydrolysis, and can well block the pinholes in the paint. However, oxides produced by pigments such as iron or scaly mica powder will reduce the permeability of the anti-corrosion coating when filling the coating, so the physical level of PPH tank can play a good role in anti-corrosion.

2. Chemical anti-corrosion: when harmful acid and alkali substances enter 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 absorbed on the steel surface, and then remain alkaline PPH storage tank It is not easy to rust in alkaline environment.

3. Electrochemical anti-corrosion: the principle of this method is that water passes through 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 as raw material is formed by special rolling process. 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. The storage tank of PPH can store and react most inorganic acids, alkalis, salt solutions and most solvents, and can partially replace stainless steel, titanium, nickel, alloy steel and other materials. This product meets the requirements for storage and transportation of dangerous goods, and is an ideal storage container for storing corrosive solutions and reactive chemical industrial cleaning solutions.
