济南气泡袋逐渐走向绿色环保之路!

发布日期:2019-10-14 作者:365体育娱乐 点击:

  气泡袋变成绿色。 随着技术的发展,气泡袋正逐步走向绿色环保的道路。 由气泡袋重复使用和回收的包装材料制成的防静电气泡袋被重复使用,并且玻璃瓶反复使用诸如啤酒,饮料,酱油,醋等的大气泡袋。 灯罩气泡袋瑞典和其他/地区已多次重复使用聚酯PET饮料瓶和PC瓶20次以上。 荧光灯管气泡袋荷兰Wellman公司和美国Johnson公司100%回收PET容器。
  Bubble bags turn green. With the development of technology, bubble bags are gradually moving towards the road of green environmental protection. Antistatic bubble bags made of reusable and recycled packaging materials are reused, and glass bottles are reused with air bubble bags such as beer, beverage, soy sauce, vinegar, etc. Sweden and other countries/regions have repeatedly reused polyester PET beverage bottles and PC bottles for more than 20 times. Fluorescent tube bubble bags Wellman Holland and Johnson USA 100% recycled PET containers.
  回收包装,例如聚酯瓶,可以在回收后以两种方式进行再生。 物理方法是指直接彻底地纯化和粉碎而没有任何残留污染物。 处理过的塑料直接用于再生包装容器。 化学方法是指将回收的PET粉碎并洗涤后,使用解聚剂甲醇水,乙二醇或二甘醇将PET解聚为单体或部分解聚为低聚物,然后进行纯化。 将该单体或低聚物再聚合成回收的PET树脂包装材料。
  Recycled packaging, such as polyester bottles, can be recycled in two ways after recycling. Physical methods refer to the direct and thorough purification and crushing without any residual pollutants. The treated plastics are directly used in recycled packaging containers. The chemical method is to crush and wash the recycled PET, then use the depolymerizer methanol water, ethylene glycol or diethylene glycol to depolymerize the PET into monomer or partial oligomer, and then purify it. The monomer or oligomer is re-polymerized into recycled PET resin packaging material.

  包装材料的回收和再利用只会延长诸如包装材料塑料之类的塑料材料的使用寿命。 当达到使用寿命时,仍然面临废物处理和环境污染的问题。 在塑料加工过程中添加少量的光敏剂会使典型的塑料变成可光降解的塑料。 由于光敏剂的光引发和光化学反应,产生自由基引发源,从而加速了聚合物的光降解过程。 包含易水解基因的聚合物和天然聚合物均具有高生物降解性。 这类塑料的降解机理是,淀粉颗粒首先被真菌和细菌攻击并消耗,从而削弱了塑料的强度,同时塑料与土壤中存在的某些盐分接触, 自氧化形成过氧化物,从而促进塑料的发展。 聚合物的分子链断裂,它们彼此促进并且彼此互补。 细菌消耗淀粉,这增加了塑料的表面积并促进了自氧化降解。 重复地,聚合物链逐渐断裂,缩短,并且塑料的强度降低,直到聚合物的分子量降低到可以被微生物代谢的程度。
  Recycling and reuse of packaging materials will only prolong the service life of plastic materials such as plastic packaging materials. When it reaches its service life, it still faces the problems of waste disposal and environmental pollution. Adding a small amount of photosensitizer in the process of plastics processing can make the typical plastics become photodegradable plastics. Photoinitiation and photochemical reaction of photosensitizers produce free radical initiator, which accelerates the photodegradation process of polymers. Polymers containing hydrolyzable genes and natural polymers have high biodegradability. The degradation mechanism of this kind of plastics is that starch particles are attacked and consumed by fungi and bacteria first, which weakens the strength of plastics. At the same time, some salts in the soil are contacted by plastics, and peroxides are formed by self-oxidation, thus promoting the development of plastics. Molecular chains of polymers break, they promote each other and complement each other. Bacteria consume starch, which increases the surface area of plastics and promotes autoxidation. Repeatedly, the polymer chains gradually break and shorten, and the strength of the plastics decreases until the molecular weight of the polymer is reduced to a level that can be metabolized by microorganisms.
