生物降解顆粒抗水性能的影響規(guī)律，得出制備SPI可生物降解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(zhì)量體積比為1:3，并采用正交組合試驗設計優(yōu)化了SPI可生物降解材料的改性條件；在佳條件下所制得的SPI可生物降解材料的拉伸強度為8.61MPa，斷裂伸長率為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.

生物降解材料隨著人類保護環(huán)境意識的提高，石油資源的不斷減少，生物降解聚合物取代傳統(tǒng)石油基聚合物已經(jīng)成為發(fā)展的趨勢。

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.

生物降解原料在適當和可表明期限的自然環(huán)境條件下，能夠被微生物完全分解變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兩類。購物袋，特別是大型和，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.

一般情況下，購物袋上都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。您有需求可以隨時來我們網(wǎng)站http://m.qylxschool.cn進行咨詢！

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. You can come to our website anytime you need http://m.qylxschool.cn Consult!
