Plastic storage tanks are made of pure polyethylene (linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE)) as raw materials and are integrally formed by a special rotational molding process. It has the advantages of no welding, no leakage, light weight, anti-aging, impact resistance, corrosion resistance and long life. The advantages of integral molding, integrity, corrosion resistance, and long life are particularly prominent. Plastic storage tanks can store and react most inorganic acids, alkalis, salt solutions and most organic solvents, and can partially replace stainless steel, titanium, nickel, high-grade alloy steel and other materials. Plastic storage tanks comply with the dangerous goods storage and transportation regulations. Ideal storage container for storage reaction chemical corrosion solution and clean solution. This product complies with national health standards and can replace stainless steel containers for shipping food-grade solutions.

Plastic storage tanks mainly have the following 7 characteristics:

1. The plastic storage tank has good integrity at one time, no welds, never leaks, impact resistance, high tensile strength, good oxidation resistance and anti-aging properties, and it meets the sanitary food standards.

2. Due to the excellent performance of linear low-density polyethylene (LLDPE) and the special structure of the plastic storage tank, the service life is more than 15 years.

3. The chemical resistance is very excellent, except for a few solutions that can swell it, it can almost be resistant to most substance solutions.

4. The plastic storage tank has the characteristics of internal and external corrosion protection, and can be placed in a highly corrosive environment.

5. General storage tank operating conditions are normal temperature and normal pressure; in special cases, storage tank operating conditions can be temperature less than 70℃ and hydraulic pressure less than 1kg/cm2.

Six. Rotomolding anticorrosive plastic storage tanks have great advantages in large-scale, large-capacity and large-volume products. Although they are large in size, they only maintain the characteristics of one-time molding integrity, which is not achieved by other storage tank processes. Place.

7. Compared with traditional anticorrosive storage tanks, the price is low and the performance-price ratio is high.

At present, the anti-corrosion storage tanks produced in China can be roughly divided into three categories: steel-plastic storage tanks, all-plastic storage tanks and FRP storage tanks. Due to the impact of the low-carbon tide, FRP storage tanks have gradually moved away from the chemical industry, replaced by all-plastic storage tanks (plastic storage tanks). It is suitable for the storage of chemical liquids in the chemical industry, biological engineering, pharmaceutical industry, pesticide industry, metallurgical industry, rare earth industry, machinery industry, power industry, steel industry, environmental protection industry, textile industry, food industry and other industries.

All-plastic storage tanks are produced by rotational molding process. The materials used include polypropylene modified materials, LLPE, HDPE blends, and special rotomolding additives (additives). The characteristics of the all-plastic storage tank are: the plastic storage tank body is integrally formed at one time, so it has the characteristics of no welding seam, no leakage, light weight, anti-aging, impact resistance, corrosion resistance, long life, and compliance with health standards. Its price is lower than stainless steel storage tanks, ordinary glass steel storage tanks, etc. Of course, longer service life under natural conditions is another aspect of rolling plastic storage tanks.
