根據原材料的不同,常見的生物降解塑料少有幾種,下面生物降解顆粒生產廠家來給大家講講相關內容。
According to different raw materials, there are at least several kinds of common biodegradable plastics. The manufacturers of biodegradable granules will tell you about them.
聚己內酯(PCL)
Polycaprolactone (PCL)
這種塑料具有良好的生物降解性,熔點是62℃。分解它的微生物廣泛地分布在喜氣或厭氣條件下。作為可生物降解材料可把它與淀粉、纖維素類的材料混合在一起,或與乳酸聚合使用。
This kind of plastic has good biodegradability, and its melting point is 62 ℃. The microorganisms that break it down are widely distributed in the pleasant or unpleasant conditions. As a biodegradable material, it can be mixed with starch and cellulose materials or polymerized with lactic acid.
聚丁二酸丁二醇酯(PBS)及其共聚物
Polybutylene succinate (PBS) and its copolymer
以PBS(熔點為114℃)為基礎材料制造各種高分子量聚酯的技術已經達到工業化生產水平。
The technology of manufacturing various high molecular weight polyester based on PBS (melting point 114 ℃) has reached the level of industrial production.
聚乳酸(PLA)
Polylactic acid (PLA)
美國Natureworks公司在完善聚乳酸生產工藝方面做了積極有效的工作,開發了將玉米中的葡萄糖發酵制取聚乳酸,年生產能力已達1.4萬噸。日本UNITIKA公司,研發和生產了許多種制品,其中帆布、托盤、餐具等在日本愛知世博會被廣泛使用。
Natureworks of the United States has made active and effective work in improving the production process of polylactic acid, and has developed the production of polylactic acid by fermenting the glucose in corn, with an annual production capacity of 14000 tons. Japan UNITIKA Company has developed and produced many kinds of products, among which canvas, tray, tableware, etc. are widely used in Aichi World Expo.
聚羥基烷酸酯(PHA)
Polyhydroxyalkanoate (PHA)
利用可再生資源得到的生物降解塑料,把脂肪族聚酯和淀粉混合在一起,生產可降解性塑料的技術也已經研究成功。在歐美,淀粉和脂肪族聚酯的共混物被廣泛用來生產垃圾袋等產品。上規模大、銷售好的是意大利的Novamont公司,其商品名為Mater-bi,公司的產品在歐洲和美國有較大量的應用。
Biodegradable plastics made from renewable resources, which mix aliphatic polyester and starch together to produce degradable plastics, have also been successfully studied. In Europe and America, the blend of starch and aliphatic polyester is widely used to produce garbage bags and other products. Novamont, an Italian company with a large scale and good sales in the world, whose trade name is Mater bi, has a large number of applications in Europe and the United States.
德國BASF公司所制造的脂肪族芳香族無規共聚酯(Ecoflex),其單體為:己二酸、對苯二甲酸、1,4-丁二醇。生產能力在14萬噸/年。同時開發了以聚酯和淀粉為主的生物降解塑料制品。
Aliphatic aromatic random copolyester (Ecoflex) manufactured by German BASF company, its monomer is adipic acid, terephthalic acid and 1,4-butanediol. The production capacity is 140000 tons/year. At the same time, biodegradable plastic products based on polyester and starch were developed.
生物降解顆粒
聚乙烯醇(PVA)類生物降解塑料
Polyvinyl alcohol (PVA) biodegradable plastics
如意大利NOVMANT的MaterBi產品在上世紀90年代主要是在淀粉中加入PVA,它能吹膜,也能加工其它產品。聚乙烯醇類材料,需要經過一定的改性后方具有良好的生物降解性能,北京工商大學輕工業塑料加工應用研究所在這方面取得了一定成果。
For example, in the 1990s, the MaterBi product of NOVMANT in Italy mainly added PVA to starch, which can blow film and process other products. Polyvinyl alcohol materials need to be modified to have good biodegradability. The Institute of Light Industrial Plastics Processing and Application of Beijing Technology and Business University has made some achievements in this regard.
二氧化碳共聚物
Carbon dioxide copolymer
國外,較早研究二氧化碳共聚物的主要為日本和美國,但一直沒有工業化生產。國內內蒙古蒙西集團公司采用長春應用化學研究所的技術,已建成年產3000噸二氧化碳/環氧化合物共聚物樹脂的裝置,產品主要應用在包裝和醫用材料上。
In foreign countries, Japan and the United States were the first countries to study carbon dioxide copolymers, but there has been no industrial production. Inner Mongolia Mengxi Group Co., Ltd. has adopted the technology of Changchun Institute of Applied Chemistry to build a device that can produce 3000 tons of carbon dioxide/epoxy copolymer resin per year. The products are mainly used in packaging and medical materials.
中科院廣州化學研究所陳立班博士開發的低分子量二氧化碳共聚物技術已在江蘇泰興開始投產,品種是低相對分子質量二氧化碳/環氧化合物共聚物,用來作為聚氨酯發泡材料的原材料,用于家用電器等的包裝。等等。
The low molecular weight carbon dioxide copolymer technology developed by Dr. Chen Liban of the Guangzhou Institute of Chemistry of the Chinese Academy of Sciences has been put into production in Taixing, Jiangsu Province. The variety is low relative molecular weight carbon dioxide/epoxy compound copolymer, which is used as the raw material of polyurethane foam materials and packaging for household appliances. wait.
