  在新的世纪,越来越严重的能源和环境问题使人们意识到环境保护的严重性,而包装材料的数量是巨大的,世界上所有的大城市都被白色垃圾困扰。因此,开发可生物降解塑料包装是非常重要的。世界上许多国家在这方面做了大量工作,取得了可喜的成果。实现生物降解材料的途径有很多,如利用天然成分进行加工;将淀粉等物质添加到树脂中,使材料能被细菌分解。开发可水解聚合物等。

  In the new century, more and more serious energy and environmental problems make people realize the seriousness of environmental protection, and the number of packaging materials is huge, all the big cities in the world are plagued by white garbage. Therefore, it is very important to develop biodegradable plastic packaging. Many countries in the world have done a lot of work in this area and achieved gratifying results. There are many ways to realize biodegradable materials, such as processing with natural ingredients, adding starch and other substances to resins, so that materials can be decomposed by bacteria. Develop hydrolyzable polymers, etc.

  合成高分子降解塑料实际上是化学合成生物降解塑料,主要包括脂族聚酯(PCLS)、聚酰胺、多糖、聚乳酸共聚物等,已经开发出许多生物降解合成聚合物,聚乳酸(PLA)、聚乙烯醇(PVA)和聚己内酯(PCLS)聚合物。聚乳酸是由乳酸单体聚合而成,乳酸单体经特殊菌种转化为淀粉。聚乳酸价格昂贵,目前主要用于医药。

  In fact, synthetic polymer degradable plastics are chemically synthesized biodegradable plastics, mainly including aliphatic polyester (PCLS), polyamide, polysaccharide, polylactic acid copolymer and so on. Many biodegradable synthetic polymers, such as polylactic acid (PLA), polyvinyl alcohol (PVA) and polycaprolactone (PCLS), have been developed. Polylactic acid is polymerized from lactic acid monomers, which are converted into starch by special strains. Polylactic acid (PLA) is expensive and is currently mainly used in medicine.

  脂肪族聚酯(如聚己内酯PCL)具有良好的生物降解性和与其他广泛使用的塑料树脂的相容性,但耐热性和物理强度较差。芳香族聚酯,如乙二醇对苯二甲酸乙二醇酯熔点高、机械强度,但降解性低、无水碳酸锌为催化剂在氮气流非混相合成共聚物,通过聚合物链之间的酯交换生产这种共聚物,不仅具有良好的生物降解性,而且还具有良好的耐热性和机械强度。
  Aliphatic polyesters (such as polycaprolactone PCL) have good biodegradability and compatibility with other widely used plastic resins, but their heat resistance and physical strength are poor. Aromatic polyesters, such as ethylene glycol terephthalate, have high melting point and mechanical strength, but low degradability. Anhydrous zinc carbonate is used as catalyst to synthesize copolymers in nitrogen immiscible flow. The copolymers produced by transesterification between polymer chains not only have good biodegradability, but also have good heat resistance and mechanical properties. Strength.
  聚乳酸是近年来发展起来的一种可降解塑料包装材料。聚乳酸的原料为乳酸,乳酸分子中既有羟基又有羧基官能团,反应活性高,在适当条件下容易脱水缩聚成聚乳酸。聚丙交酯可通过直接缩聚和开环聚合合成。可降解材料可由合成聚乳酸或发酵葡萄糖、麦芽糖、谷物甜汁或马铃薯淀粉制成。堆肥约在一个月内降解,可被海水中的微生物吸收。可生物降解材料制造商,建议您选择安徽鑫科生物环保有限公司。安徽鑫科生物环保有限公司主要从事生物可降解材料,可降解材料,可降解颗粒,玉米淀粉,淀粉可生物降解材料研究、开发和生产,是一种新型的绿色环保材料领域,集技术研发、规模生产和销售为一体的专业公司,想要了解更多内容,欢迎访问可降解颗粒网站:http://www.swjjkl.com
  Polylactic acid (PLA) is a kind of degradable plastic packaging material developed in recent years. The raw material of polylactic acid is lactic acid. The molecule of lactic acid has both hydroxyl and carboxyl groups. It has high reactivity and is easy to dehydrate and polycondensate to polylactic acid under appropriate conditions. Polylactide can be synthesized by direct condensation and open ring polymerization. Degradable materials can be made from synthetic polylactic acid or fermented glucose, maltose, cereal juice or potato starch. The compost is degraded in about one month and can be absorbed by microorganisms in seawater. As a manufacturer of biodegradable materials, we recommend that you choose Anhui Xinke Biological Environmental Protection Co., Ltd. Anhui Xinke Bio-environmental Protection Co., Ltd. is mainly engaged in the research, development and production of biodegradable materials, biodegradable materials, degradable granules, corn starch and starch biodegradable materials.
