環(huán)保的話題一直熱度不減，你知道有哪些可降解材料可以代替塑料嗎？下面可降解顆粒生產(chǎn)廠家為你分析：

The topic of environmental protection has always been hot. Do you know what biodegradable materials can replace plastics? The following manufacturers of degradable particles will analyze for you:

可降解材料，是指在一段時(shí)間內(nèi)，可在太陽(yáng)光、溫度、水、化合物、真菌細(xì)菌等微生物，昆蟲(chóng)，機(jī)械力等自然環(huán)境條件下，被分解為二氧化碳和水等元素的材料。目前，市場(chǎng)上常見(jiàn)的有三類(lèi)環(huán)保可降解材料。

Degradable materials refer to materials that can be decomposed into carbon dioxide, water and other elements under natural environmental conditions such as sunlight, temperature, water, compounds, fungi and bacteria, insects, mechanical forces and so on. At present, there are three types of environmentally friendly degradable materials in the market.

一、聚乳酸

1、 Polylactic acid

聚乳酸又稱(chēng)聚丙交酯，是以微生物發(fā)酵產(chǎn)物乳酸為單體化學(xué)合成的。使用后可自動(dòng)降解，不會(huì)污染環(huán)境。

Poly (lactic acid), also known as polylactide, is chemically synthesized with lactic acid, a product of microbial fermentation, as a monomer. It can be degraded automatically after use and will not pollute the environment.

二、淀粉塑料

2、 Starch plastic

淀粉塑料，指在PP等塑料中添加一定量玉米淀粉、木薯粉、木粉、竹粉等，達(dá)到環(huán)保可降解的目的。含淀粉90%以上的淀粉塑料，添加的其他組份也是能降解的。

Starch plastic refers to adding a certain amount of corn starch, cassava powder, wood powder, bamboo powder, etc. to PP and other plastics to achieve the purpose of environmental protection and degradability. Starch plastics containing more than 90% starch can also be degraded by other components added.

三、光降解塑料

3、 Photodegradable plastics

光降解塑料是指在光的作用下能發(fā)生降解的塑料，通過(guò)化學(xué)合成或添加光敏劑獲得。

Photodegradable plastic refers to the plastic that can degrade under the action of light, which is obtained by chemical synthesis or adding photosensitizer.
