根據(jù)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(chǎn)廠家來給大家講講相關(guān)內(nèi)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(nèi)酯(PCL)
Polycaprolactone (PCL)
這種塑料具有良好的生物降解性,熔點(diǎn)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(diǎn)為114℃)為基礎(chǔ)材料制造各種高分子量聚酯的技術(shù)已經(jīng)達(dá)到工業(yè)化生產(chǎn)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(chǎn)工藝方面做了積極有效的工作,開發(fā)了將玉米中的葡萄糖發(fā)酵制取聚乳酸,年生產(chǎn)能力已達(dá)1.4萬噸。日本UNITIKA公司,研發(fā)和生產(chǎn)了許多種制品,其中帆布、托盤、餐具等在日本愛知世博會(huì)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(chǎn)可降解性塑料的技術(shù)也已經(jīng)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(chǎn)垃圾袋等產(chǎn)品。上規(guī)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(chǎn)品在歐洲和美國有較大量的應(yīng)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(guī)共聚酯(Ecoflex),其單體為:己二酸、對(duì)苯二甲酸、1,4-丁二醇。生產(chǎn)能力在14萬噸/年。同時(shí)開發(fā)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(chǎn)品在上世紀(jì)90年代主要是在淀粉中加入PVA,它能吹膜,也能加工其它產(chǎn)品。聚乙烯醇類材料,需要經(jīng)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(xué)輕工業(yè)塑料加工應(yīng)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(yè)化生產(chǎn)。國內(nèi)內(nèi)蒙古蒙西集團(tuán)公司采用長(zhǎng)春應(yīng)用化學(xué)研究所的技術(shù),已建成年產(chǎn)3000噸二氧化碳/環(huán)氧化合物共聚物樹脂的裝置,產(chǎn)品主要應(yīng)用在包裝和醫(yī)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(xué)研究所陳立班博士開發(fā)的低分子量二氧化碳共聚物技術(shù)已在江蘇泰興開始投產(chǎn),品種是低相對(duì)分子質(zhì)量二氧化碳/環(huán)氧化合物共聚物,用來作為聚氨酯發(fā)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.
