Performance of polyethylene storage tanks

PE all plastic storage tank is also known as rolling plastic water tank. Its product performance requirements stipulate that it can only store certain specific liquid substances. If not handled properly, it can cause the plastic storage tank to collapse and soften, and in severe cases, it may even be scrapped. How to prevent the occurrence of soft collapse, bulging and bulging of PE plastic storage tanks. The raw material for the 1-ton roof rainwater collection bucket PE (plastic) storage tank is rotational plastic raw material, which is a linear low-density polyethylene (LLDPE) or linear medium density polyethylene (LMDPE). Compared to high-density polyethylene (HDPE), PE is just a general term. Plastic storage tanks can store most substances such as inorganic acids, alkalis, salts, and many organic compounds at room temperature. Polyethylene rotational molding storage tank products are not suitable for containing strong oxidants (such as sulfuric acid with a concentration of over 75% and concentrated nitric acid with a concentration of over 30% at a temperature of 60 ℃) and good organic solvents (benzene, ether, ketone, ester). The plastic raw materials used in polyethylene PE storage tanks have a low softening point of 108 ℃ and a high fragmentation point of -70 ℃, so they generally cannot store liquids with temperatures below 40 ℃ or above 65 ℃. If the liquid density is heavy or the temperature is higher than 65 ℃, a steel lined plastic anti-corrosion storage tank should be considered to prevent the full plastic storage tank from collapsing and bulging. If the PE rotational molding storage tank is used for chemical reaction or dilution, corresponding tests should be conducted before storage to determine the higher temperature of reaction or dilution. According to the characteristics of the raw materials in the storage tank, appropriate materials should be filled to avoid incorrect use and cause softening deformation of the storage tank. A 1-ton PE plastic water tank is also an indispensable plastic container for environmental protection professions. In environmental water treatment, it is used as a storage, reaction, filtration, sedimentation, and transportation container. In hospital wastewater treatment, environmental protection professions are inseparable from PE dosing tanks. PE dosing mixing tanks, chemical storage tanks, intermediate storage tanks, etc. are all inseparable from PE plastic dosing tanks.
