Abstract

The invention discloses a material of a container for depositing a superhigh-purity reagent. According to the material provided by the invention, polyethylene with three molecular weights and a small quantity of polytetrafluoroethylene are selected as materials, and the materials include the following components by weight percent: 3-5% of low molecular weight polyethylene, 80-82% of common molecular weight polyethylene, 5-8% of high molecular weight polyethylene, 1-5% of superhigh molecular weight polyethylene and 2-9% of common molecular weight polytetrafluoroethylene; all materials are uniformly mixed and then are prepared into the plastic container through utilizing a plastic processing device and a plastic mould. The materials can extremely express the advantages of the polyethylene with different molecular weights and different molecular densities and also generate the different corrosion-resisting and anti-oxidizing effects. The plastic container which is manufactured by the material has the advantages of strong acid resistance, strong base resistance, strong oxidization resistance and good compatible performance; and physical performances and mechanical performances of the plastic container are better than those of the traditional common plastic container.

Description

technical field [0001] The invention relates to packaging materials, in particular to a material for producing ultra-high purity reagent containers. Background technique [0002] In the prior art, there are many types of plastic packaging containers. The use requirements of plastic packaging containers in most industries, as long as they meet the requirements of low cost, durability, certain strength, certain toughness, and good aging resistance, they can be used for packaging Food and drug plastic containers should also meet the requirements of not causing pollution to food and drugs. At present, the materials used in the production of plastic packaging containers mainly include polyethylene plastics and polyvinyl chloride. Because polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance, good chemical stability, can withstand most of the acid and alkali erosion generally required, is insoluble in general solvents at room temperature, h...
