Description
Technical field
The present invention relates to wrapping material, be specifically related to a kind of raw material that is used to produce plastic containers.
Background technology
The kind of plastic packaging containers is more in the prior art, the service requirements of plastic packaging containers in most of industries, as long as satisfy with low cost, durable, have certain intensity, a certain toughness, ageing resistance is better, and the plastic containers that are used for wrap food, medicine also should satisfy not the requirement to aspects such as food, medicine pollute.Produce the employed raw material of plastic packaging containers at present and mainly contain vinyon, polyvinyl chloride etc.Because the polyethylene odorless, nontoxic, the feel ceraceous has good resistance to low temperature, and chemical stability is good, and the erosion of most of soda acids of ability general requirement is insoluble to common solvent under the normal temperature, and water-absorbent is little, and electrical insulation capability is good.Therefore, in the production of packaging vessel, obtained using widely.
But the existing raw material that is used to produce plastic containers all is the polyethylene of selecting unimodal molecular weight, single molecular density for use basically.Because different molecular weight, different densities, the poly physics of different molecular structures, chemistry, mechanical property differ bigger.The acid resistance of some plastic containers is better, but alkaline resistance properties is relatively poor, and the alkaline resistance properties of some plastic containers is better, but acid resistance is relatively poor, the plastic containers of some acid-fast alkali-proof better performances, but its antioxidant property again can be relatively poor.Owing in the production process of plastics, need to add some kinds of auxiliary materials, and also can contain impurity in the raw material of plastics, therefore, the plastic containers of above-mentioned poor-performing in one aspect are after a kind of solution or reagent are placed into, plastic containers will be corroded, and at this moment some supplementary additives in the raw material and impurity can be dissolved in the liquid or solvent that is installed with ionic state or with particulate form (comprising metal ion and particle).And in some special industries, as semiconductor integrated circuit, the TFT-LCD flat-panel screens, the electronic chemical product that the photovoltaic industry is used to produce, then higher to the service requirements of packing plastic bottle.Contain various impurity in liquid after owing to be corroded or the solvent, this liquid or solvent will cause the short circuit of electron device, or open circuit, or the change of electrical property, cause product rejection.
Along with developing rapidly of semiconductor technology, more and more higher to the requirement of high-purity scavenging solution of ultra-clean or reagent, its purity and cleanliness factor have very great influence to yield rate, electrical property and the reliability of unicircuit.The solution of ultra-high purity and/or reagent have been widely used in aspects such as cleaning in semi-conductor, the large-scale integrated circuit course of processing, drying as a kind of important microelectronics chemistry product.Along with the finish size of IC has entered submicron, deep-submicron epoch, solution and/or reagent to supporting with it ultrapure clear height purity degree are had higher requirement, require particle and foreign matter content to reach the SEMIC8-SEMI C12 standard of semiconductor equipment and material structure formulation, wherein metallic cation content is controlled at the PPT rank, and granular size is controlled at below the 0.2 μ m.
In order to satisfy the requirement of electron trade to ultra-clean and high pure chemical reagent, satisfy the requirement with low cost of plastic containers simultaneously, be necessary to develop a kind of plastic containers of New Type Material.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the prior art, design a kind of raw material that is used to produce plastic containers, these plastic containers are difficult for being corroded by strong acid, highly basic, strong oxidizer, compatible superior performance, and the basic raw materials cost with existing plastic containers of the cost of this raw material is basic identical.
For achieving the above object, technical scheme of the present invention provides a kind of raw material that is used to produce plastic containers, it is characterized in that, it is raw material that described plastic containers are selected the polyethylene of 3 kinds of molecular weight at least for use, including in described raw material is 3%～8% low molecular weight polyethylene, 80%～85% common molecular weight polyethylene, 7%～10% High molecular weight polyethylene and 1%～5% ultrahigh molecular weight polyethylene(UHMWPE) by weight percentage, and above-mentioned raw materials proportionally mixes the back and makes described plastic containers by device of plastic processing and mould of plastics.
Wherein, the polyethylene and the highdensity polyethylene that in described low molecular weight polyethylene, common molecular weight polyethylene and High molecular weight polyethylene, include low-density polyethylene, middle density again respectively.
Wherein, in the polyethylene raw material of described various molecular weight, the shared weight percent of described low-density polyethylene is 2%～8%, and the shared weight percent of polyethylene of described middle density is 12%～15%, and the shared weight percent of described highdensity polyethylene is 77%～86%.
