生物降解顆粒抗水性能的影響規律

生物降解顆粒抗水性能的影響規律，得出製備SPI可生物降解（jiě）材料的改性工藝條件為：

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與四氫呋喃的質量體積比為1:3，並采用（yòng）正交組合試驗設計優化了SPI可生（shēng）物降解材（cái）料的改性條件；在佳條件下所製（zhì）得的SPI可生物降解（jiě）材料的拉伸強度為8.61MPa，斷裂伸長率為（wéi）196.78%，吸水率為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（shēng）物降解材（cái）料隨著人類保護（hù）環境意識的提高，石油資（zī）源的不斷減少，生物降解聚合物取代傳統（tǒng）石（shí）油基聚合物已經成為發（fā）展的趨勢（shì）。

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.

生物降解原（yuán）料在適當和可表明期限的自然環境條件下，能夠（gòu）被微生物完全分解變成（chéng）低分子化合物（wù）的材料（liào）。

Biodegradable materials can be completely decomposed into low molecular compounds by microorganisms under appropriate and demonstrable natural environmental conditions.

生物（wù）降解陶瓷和生物降解性塑料兩類。購物袋，特別（bié）是大型和（hé），購物時使用背心購物袋。

Biodegradable ceramics and biodegradable plastics. Shopping bags, especially in large supermarkets and shopping malls, use vest shopping bags when shopping.

一般情（qíng）況下，購物袋上都（dōu）印有標識或宣傳信息，這種可生物降解的塑料袋需要專門做成塑料廣告袋，所以購物袋是固定的。您有需求（qiú）可以隨時來我們網站https://www.shuiniguan.com進行谘詢！

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.
