生物降解颗粒抗水性能的影响规律,得出制备SPI可生物降解材料的改性工艺条件为:
The influence rule of the water resistance of biodegradable particles shows that the modification process conditions for preparing SPI biodegradable materials are as follows:
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;在佳条件下所制得的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%。
The mass volume ratio of SPI to tetrahydrofuran was 1:3, and the modification conditions of SPI biodegradable materials were optimized by orthogonal combination design; The tensile strength, elongation at break and water absorption of SPI biodegradable material prepared under optimal conditions are 8.61MPa, 196.78% and 31.6% respectively.
生物降解材料随着人类保护环境意识的提高,石油资源的不断减少,生物降解聚合物取代传统石油基聚合物已经成为发展的趋势。
Biodegradable materials with the improvement of human awareness of environmental protection, the continuous reduction of petroleum resources, biodegradable polymers to replace traditional petroleum based polymers has become a development trend.
生物降解颗粒
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。
Biodegradable materials can be completely decomposed into low molecular compounds by microorganisms under appropriate and demonstrable natural environmental conditions.
生物降解陶瓷和生物降解性塑料两类。购物袋,特别是大型和,购物时使用背心购物袋。
Biodegradable ceramics and biodegradable plastics. Shopping bags, especially in large supermarkets and shopping malls, use vest shopping bags when shopping.
一般情况下,购物袋上都印有标识或宣传信息,这种可生物降解的塑料袋需要专门做成塑料广告袋,所以购物袋是固定的。您有需求可以随时来我们网站https://www.qiluxinke.com进行咨询!
Generally, supermarket shopping bags are printed with supermarket logo or supermarket publicity information. This biodegradable plastic bag needs to be specially made into a plastic advertising bag, so supermarket shopping bags are fixed.
