Description
Technical Field
The invention relates to the technical field of plastic packaging barrels, in particular to a production and preparation method of a high-strength packaging barrel.
Background
The packing barrel is mainly used for storing and transporting various liquids, has good characteristics for special dangerous goods packages, has the characteristics of low probability of breakage, no rustiness, light weight and the like, has oil resistance and strong corrosion resistance, is mainly used for packing dangerous goods with heat preservation, moisture resistance, pressure resistance and corrosion resistance, and is made of polyethylene materials in common production.
Polyethylene (PE) is a thermoplastic resin obtained by polymerizing ethylene. In industry, copolymers of ethylene with small amounts of alpha-olefins are also included. The polyethylene is odorless and nontoxic, feels like wax, has excellent low-temperature resistance (the lowest use temperature can reach-100 to-70 ℃), has good chemical stability, and can resist corrosion of most of acid and alkali (cannot resist acid with oxidation property). Is insoluble in common solvents at room temperature, has low water absorption and excellent electrical insulation.
The polyethylene resin is non-toxic and tasteless white powder or granules, is milky white in appearance, has a wax-like hand feeling, and has low water absorption rate of less than 0.01 percent. Polyethylene films are transparent and decrease with increasing crystallinity. Polyethylene films have low water permeability but high air permeability and are not suitable for freshness packaging but for moisture-proof packaging. The flame is inflammable, the oxygen index is 17.4, the flame is low in smoke during combustion, a small amount of molten drops exist, the flame is yellow on the top and blue on the bottom, and the paraffin smell exists. Polyethylene has good water resistance. The product surface is non-polar, difficult to adhere and print, and improved by surface treatment. Branched polymers are poorly resistant to photodegradation and oxidation.
The molecular weight is in the range of 1 to 10 ten thousand. Ultra-high molecular weight polyethylene having a molecular weight of more than 10 ten thousand. The higher the molecular weight, the better the physical and mechanical properties, and the closer to the required level of engineering materials. However, the higher the molecular weight, the more difficult it is to process. The polyethylene has a melting point of 100-130 ℃ and excellent low-temperature resistance. The mechanical property can still be kept at-60 ℃, but the use temperature is 80-110 ℃. It is insoluble in any known solvent at normal temperature, and can be dissolved in a small amount in solvents such as toluene, amyl acetate, trichloroethylene and the like at the temperature of more than 70 ℃.
