(1) Processing technology of polyethylene storage tank:
Polyethylene (PE) horizontal storage tanks are made of pure polyethylene (linear low-density polyethylene (LLDPE), high-density polyethylene (HDPE)) as raw materials, and are integrally formed at one time by a rotational molding process.
(2) Processing technology of steel-lined plastic storage tank:
Steel-lined plastic vertical storage tank, also known as tortoise-shell-lined storage tank (tortoise-shell lining-steel, mesh, and plastic three in one) is the essence of steel-plastic composite series products. It uses a special rotational molding process. It welds the steel mesh (tortoise shell) to the surface of the steel body, uses pure polyethylene (linear low-density polyethylene LLDPE, high-density polyethylene HDPE) as the raw material, and uses the rotomolding process to combine the steel plate, the steel mesh (tortoise shell) and the polyethylene organically. Combine into one. Polyethylene adheres firmly to the surface of the steel body. The product has the advantages of no welding seam, no leakage, no toxicity, anti-aging, anti-impact, anti-corrosion, long life, conforming to sanitary standards, etc. It makes up for the shortcomings of all-plastic rotomolded storage tanks of poor rigidity, strength, pressure, and temperature difference.
