Hebei Nikko container manufacturing plant 10 tons pe tanks, 20 tons, 30 tons and other large storage tanks, tank ①pe heterosexual processed custom tank forming a good integrity, no welds, never leakage, strong shock resistance high tensile strength, anti-oxidation, anti-aging? is good, in line with food hygiene standards. ② the linear low density polyethylene (LLDPE) excellent performance and rotomolding tank special structure, the service life of more than 15 years. ③ very excellent chemical resistance, corrosion resistance, anti-aging. ④ plastic tanks have internal and external corrosion, and can be placed in highly corrosive environments. General conditions for the tank ⑤ normal temperature and pressure; special cases, the condition may be a storage tank using a temperature lower than 70 ℃ and hydraulic less than 1kg / cm2?. ⑥ rotomolding tank corrosion on large-sized large-capacity bulk products have a very big advantage, though bulky, but only once and then keep forming? Holistic characteristics, which is less than the storage tanks at the other processes are up . ⑦ compared to traditional tank corrosion, low prices, is currently on the market for all container products in the most cost effective method of acceptance (1) Appearance: Barrel symmetrical parts of the wall thickness ratio of not more than 2: 1, no blisters, no adverse plastics , the outer wall, the mouthpiece smooth and clean, less than 2mm in diameter bubbles no more than two, black spots impurities length of not more than 4mm, barrel mouthpiece coincide closely, good interchangeability. ?? (2) performance test: open plastic container to carry out vertical impact drop test, stacking test, seal test. Closed plastic container to carry out vertical impact drop test, stacking test, tightness test, hydraulic test. Mounted handle and integral handle plastic container hanging test needs to be done. ?? ① vertical impact drop test: The specimen at -18 ℃ conditions. Drop height: such as water as an alternative to the proposed loading merchandise density of not more than 1.2 to 0.8m; intended to contain merchandise density greater than 1.2, the drop height was 0.67m × density. See drop site SN / T0271 "inspection of export commodities transport packaging plastic containers." ?? ② stacking test: the test temperature 40 ℃, stacking time of 7 days. ?? Stacking quality is calculated as follows: ?? M0 = (H / h-1) × M1 where:?? Stacking exerted on quality M0-- plastic container, kg ;?
