Preventive measures against softening and deformation of PE storage tanks:
1. The feeding and discharging ports, level gauge openings, flanges, etc., on the PE tank body are all formed in one piece without welding, eliminating the need for additional feeding and discharging ports. When storing acidic or alkaline substances, acid-resistant and alkaline-resistant gaskets must be used. When storing **substances (especially),** non-dissolving rubber gaskets should be installed.
2. PE plastic storage tanks are not suitable for containing strong oxidizing agents (such as those with a concentration of over 75% at 60℃ and over 30%), as well as good ones (such as alcohols, ethers, ketones, esters), etc.
3. The PE tanks are formed using the rotational molding process.
4. Our company's PE plastic storage tanks are made of extruded plastic—linear low-density polyethylene (LLDPE) or linear medium-density polyethylene (LMDPE). These tanks are suitable for storing most alkalis, salts, and many other substances at room temperature.
5. The PE plastic storage tanks have a low softening point of 108°C and a high fracture point of -70°C, making them generally suitable for storing liquids at temperatures between -40°C and 60°C. For liquids with a higher specific gravity or temperatures exceeding 60°C, a steel-lined plastic corrosion-resistant tank should be used to prevent softening and deformation of the PE plastic tank. If the PE plastic tank is to be used for chemical reactions or dilutions, appropriate tests should be conducted beforehand to determine the high temperatures involved in the reaction or dilution. The product performance of the PE storage tanks includes a low softening point of 108°C and a high fracture point of -70°C, suitable for storing liquids at temperatures from -40°C to 60°C. For liquids with a higher specific gravity or temperatures exceeding 60°C, a steel-lined plastic corrosion-resistant tank should be used to prevent softening and deformation of the PE plastic tank. Prior testing should be conducted for chemical reactions or dilutions to determine the high temperatures involved.
