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(yàn)設(shè)計(jì)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(qiáng)度為8.61MPa，斷裂伸長(zhǎng)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(lèi)保護(hù)環(huán)境意識(shí)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(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.

生物降解原料在適當(dāng)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(lèi)。購(gòu)物袋，特別是大型和，購(gòu)物時(shí)使用背心購(gòu)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(gòu)物袋上都印有標(biāo)識(shí)或宣傳信息，這種可生物降解的塑料袋需要專(zhuān)門(mén)做成塑料廣告袋，所以購(gòu)物袋是固定的。您有需求可以隨時(shí)來(lái)我們網(wǎng)站http://yphk.com.cn進(jìn)行咨詢(xún)！

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.
