塑料袋的成分主要有哪些组成?

发布日期:2019-08-22 作者:www.edkiller.com 点击:

  我们通常使用的塑料不是纯物质。它由许多材料制成。其中高分子(或称合成树脂)是塑料的主要成分,此外,为了提高塑料的性能,还在聚合物中加入各种辅助材料,如填料、润滑剂、增塑剂、着色剂、稳定剂等,使塑料成为性能良好的塑料。
  The plastics we usually use are not pure substances. It is made of many materials. Polymer (or synthetic resin) is the main component of plastics. In addition, in order to improve the properties of plastics, various auxiliary materials such as fillers, lubricants, plasticizers, colorants and stabilizers are added to the polymer to make plastics become plastics with good properties.
  1. 润滑剂
  1. Lubricants
  使用润滑剂防止塑料在成型过程中粘在金属模具上,使塑料表面光滑美观。常用的润滑剂有硬脂酸和钙镁盐等。
  Lubricant is used to prevent plastics from sticking to metal moulds in the forming process, so that the surface of plastics is smooth and beautiful. Commonly used lubricants are stearic acid and calcium magnesium salts.
  2. 着色剂
  2. Colorants
  着色剂能使塑料具有各种鲜艳美丽的颜色。有机染料和无机颜料是常用的着色剂。
  Colorants give plastics a variety of bright and beautiful colors. Organic dyes and inorganic pigments are common colorants.
  3、稳定剂
  3. Stabilizers
  为了防止合成树脂在加工和使用过程中受到光热分解和破坏,延长使用寿命,在塑料中加入稳定剂。常用的有硬脂酸盐、环氧树脂等。
  In order to prevent the photothermal decomposition and destruction of synthetic resins in the process of processing and use and prolong their service life, stabilizers were added to plastics. Stearate and epoxy resin are commonly used.

  4. 塑化剂
  4. Plasticizer
  增塑剂能提高塑料的塑性和柔软度,降低脆性,使塑料易于加工成型。增塑剂一般可与树脂混溶,无毒、无味、轻、热稳定的高沸点有机化合物,常用的是邻苯二甲酸酯类。例如,在聚氯乙烯塑料的生产中,添加更多的增塑剂可以得到柔软的聚氯乙烯塑料,如果不添加或添加较少的增塑剂(用量< 10%),然后是硬质PVC塑料。
  Plasticizer can improve plasticity and softness of plastics, reduce brittleness and make plastics easy to process. Plasticizers can generally be mixed with resins, non-toxic, odorless, light, heat-stable high boiling point organic compounds, the most commonly used is phthalates. For example, in the production of PVC plastics, soft PVC plastics can be obtained by adding more plasticizers. If no plasticizers are added or fewer plasticizers are added (dosage < 10%), then rigid PVC plastics.
  5、包装
  5. Packaging
  填料,又称填料,能提高塑料的强度和耐热性,降低成本。例如,在酚醛树脂中加入木粉可以大大降低成本,使酚醛塑料成为便宜的塑料之一,并显著提高机械强度。填料可分为有机填料和无机填料,前者如木粉、抹布、纸张和各种织物纤维,后者如玻璃纤维、石棉、硅藻土、炭黑等。
  Fillers, also known as fillers, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood flour to phenolic resin can greatly reduce costs, make phenolic plastics one of the cheapest plastics, and significantly improve mechanical strength. Fillers can be divided into organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, the latter such as glass fiber, asbestos, diatomite, carbon black and so on.
  6、合成树脂
  6. Synthetic resins
  合成树脂是塑料中重要的成分,其在塑料中的含量一般为40% ~ 100%。树脂通常被认为是塑料的同义词,因为它的高含量,因为树脂的性质往往决定塑料的性质。例如,聚氯乙烯树脂与聚氯乙烯塑料、酚醛树脂与酚醛塑料混淆。实际上树脂和塑料是两个不同的概念。树脂是一种原始聚合物,不仅用于制造塑料,还用于涂料、粘合剂和合成纤维。然而,大多数塑料除了其主要成分树脂外,还需要添加其他物质。
  Synthetic resin is the most important component in plastics, and its content in plastics is generally 40%-100%. Resins are often considered synonymous with plastics because of their high content, because the properties of resins often determine the properties of plastics. For example, polyvinyl chloride resin is confused with polyvinyl chloride plastics, phenolic resin and phenolic plastics. In fact, resins and plastics are two different concepts. Resin is a primitive polymer used not only in the manufacture of plastics, but also in coatings, adhesives and synthetic fibers. However, most plastics need to add other substances besides resins, which are the main component.
