生物技术降解原材料指在进行土壤结构分层里能被微生物菌苗融解的塑料,凭着细菌或其水解产生反应以及水果酵素能将企业原材料融解为二氧化碳、水、蜂巢状多孔建筑材料作为原材料和磷酸盐,她们需要进一步经微生物菌苗作用后能溶,再度进到中国生态经济体系,是现如今这个世界发展各国教育科研与设计研究开发的实时关注热点。生物降解原料在适当和可表明期限的自然环境条件下,能够被微生物完全分解变成低分子化合物的材料。生物降解陶瓷和生物降解性塑料两类。

The biodegradable raw materials refer to the plastics that can be dissolved by microbial vaccine in the layered soil structure. The raw materials of enterprises can be dissolved into carbon dioxide, water and honeycomb porous building materials as raw materials and phosphates by bacteria or their hydrolysis reaction and fruit enzymes. They need to be further dissolved by microbial vaccine, Entering China's ecological economic system again is a real-time focus of educational research and design research and development in the developing countries of the world. Biodegradable raw materials can be completely decomposed into low molecular weight compounds by microorganisms under appropriate and demonstrable natural environmental conditions. There are two kinds of biodegradable ceramics and biodegradable plastics.

生物降解颗粒抗水性能的影响规律,得出制备SPI可生物降解材料的好改性工艺条件为:SPI与四氢呋喃的质量体积比为1:3,并采用正交组合试验设计优化了SPI可生物降解材料的改性条件;在好条件下所制得的SPI可生物降解材料的拉伸强度为8.61MPa,断裂伸长率为196.78%,吸水率为31.6%。pbat属于热塑性生物降解塑料,是己二酸丁二醇酯和对苯二甲酸丁二醇酯的共聚物,兼具PBA和PBT的特性,既有较好的延展性和断裂伸长率,也有较好的耐热性和冲击性能;此外,还具有优良的生物降解性,是生物降解塑料研究中非常活跃和市场应用降解材料之一。
According to the influence law of water resistance of biodegradable particles, the good modification process conditions for preparation of SPI biodegradable materials were obtained as follows: the mass volume ratio of SPI and tetrahydrofuran was 1:3, and the modification conditions of SPI biodegradable materials were optimized by orthogonal combination design; The results show that the tensile strength, elongation at break and water absorption of SPI biodegradable material are 8.61 MPa, 196.78% and 31.6% respectively. PBAT is a kind of thermoplastic biodegradable plastics. It is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA and PBT. It has good ductility, elongation at break, heat resistance and impact resistance; In addition, it has excellent biodegradability, and is one of the most active biodegradable materials in the research and market application of biodegradable plastics.
因此,生物化学降解原材料成本一般指具有存在一定的断裂韧性、可以在地形地貌中全部或一部分被(微生物菌苗如细菌、黄曲霉菌和藻类植物)融解而不造成环境治理污染的新型工程塑料。生物发生降解的基本工作原理分析关键由细菌或其核糖核苷酸将高相对性分子生活质量的聚合物转换成小相对性分子信息质量的碎片,接着我们进一步被细菌融解为二氧化碳和水等化合物。
Therefore, the cost of raw materials for biochemical degradation generally refers to the new engineering plastics with certain fracture toughness, which can be completely or partially dissolved in the topography (such as bacteria, Aspergillus flavus and algae) without causing environmental pollution. The key to the analysis of the basic working principle of biodegradation is that bacteria or their ribonucleotides convert polymers with high relative molecular quality of life into fragments with low relative molecular information quality, and then we are further decomposed by bacteria into compounds such as carbon dioxide and water.
目前,可生物降解原料已被设计、开发和生产成不同的产品:一是可降解的环氧树脂和母粒,包括完全可生物降解的环氧树脂、光微生物双降解母粒和复合可降解母粒等。
At present, biodegradable raw materials have been designed, developed and produced into different products: one is degradable epoxy resin and masterbatch, including fully biodegradable epoxy resin, photo microbial dual degradation masterbatch and composite degradable masterbatch.
