可降解垃圾袋的使用分類(lèi)及特點(diǎn)介紹

可降解垃圾袋的主要原料是可降解塑料。這是一種特殊的高分子聚合物,其特點(diǎn)是隨著產(chǎn)品生命周期的結(jié)束,分子量會(huì)自動(dòng)降低,塑料會(huì)變脆變軟,容易開(kāi)裂,失去機(jī)械強(qiáng)度??山到饫煌谄胀ㄋ芰洗F胀ㄋ芰洗褂煤舐裨诘叵乱?jīng)過(guò)幾百年才能自然降解。然而,填埋或焚燒也會(huì)對(duì)環(huán)境造成污染??山到饫某霈F(xiàn)為減少白色污染、保護(hù)環(huán)境做出了重要貢獻(xiàn)。

The main raw material of degradable Bin bag is degradable plastic. This is a special high molecular polymer, which is characterized by that with the end of the Product lifecycle, the molecular weight will automatically reduce, the plastic will become brittle and soft, easy to crack, and lose mechanical strength. The biodegradable Bin bag is different from the ordinary plastic bag. It takes hundreds of years for ordinary plastic bags to naturally degrade when buried underground after use. However, landfill or incineration can also cause environmental pollution. The emergence of degradable Bin bag has made an important contribution to reducing white pollution and protecting the environment.
可降解垃圾袋是指在塑料袋生產(chǎn)過(guò)程中,在塑料原料中添加一定量的淀粉、變性淀粉、纖維素、生物降解劑等添加劑,從而降低可降解垃圾袋的塑料穩(wěn)定性,使其在自然環(huán)境中更容易降解。

Degradable Bin bag refers to the addition of a certain amount of starch, modified starch, cellulose, biodegradable agent and other additives in the plastic raw materials during the production of plastic bags, so as to reduce the plastic stability of the degradable Bin bag and make it easier to degrade in the natural environment.
市場(chǎng)上常用的可降解垃圾袋有兩種。一種是以PBAT和PLA為原料,淀粉制成的可降解材料。這種材料產(chǎn)生的垃圾袋分解后可以完全轉(zhuǎn)化為水和二氧化碳。除了用來(lái)生產(chǎn)可降解垃圾袋,還可以用來(lái)生產(chǎn)各種購(gòu)物袋和一次性塑料薄膜。這種可降解塑料材料的缺點(diǎn)是強(qiáng)度低,高,在生產(chǎn)中會(huì)產(chǎn)生大量的廢料,但是這些廢料很難回收利用,所以PBAT和PLA材料制成的可降解垃圾袋成本很高,是普通垃圾袋的3-5倍。
There are two kinds of degradable Bin bag commonly used in the market. One is a biodegradable material made from starch using PBAT and PLA as raw materials. The Bin bag produced by this material can be completely converted into water and carbon dioxide after decomposition. In addition to producing biodegradable Bin bag, it can also be used to produce various shopping bags and disposable plastic films. The disadvantage of this biodegradable plastic material is its low strength and high price. It will produce a large amount of waste materials in production, but these waste materials are difficult to recycle. Therefore, the cost of biodegradable Bin bag made of PBAT and PLA materials is high, 3-5 times that of ordinary Bin bag.
另一種可降解垃圾袋是由生物基塑料制成的。除了普通的HDPE、LDPE等材料和淀粉之外,還有很多種類(lèi)的添加劑,而且淀粉含量非常高,可以高達(dá)15以上。通過(guò)顯微鏡觀察,我們可以看到生物基塑料生產(chǎn)的可降解垃圾袋內(nèi)部結(jié)構(gòu)由許多蜂窩孔組成。這些蜂窩孔的設(shè)計(jì)大大增加了產(chǎn)品與空氣的接觸面積,加快了垃圾袋在分解過(guò)程中的氧化速度。此外,生物基塑料原料中含有多種添加劑,能可降解垃圾袋的速度,使垃圾袋在短時(shí)間內(nèi)脆化分解成無(wú)數(shù)對(duì)環(huán)境無(wú)害的微小顆粒。
Another biodegradable Bin bag is made of bio based plastic. In addition to ordinary HDPE, LDPE and other materials and starch, there are also many types of additives, and the starch content is very high, which can reach over 15. Through microscope observation, we can see that the internal structure of biodegradable Bin bag produced by bio based plastics is composed of many honeycomb holes. The design of these honeycomb holes greatly increases the contact area between the product and the air, and speeds up the oxidation speed of Bin bag in the decomposition process. In addition, the bio based plastic raw materials contain a variety of additives, which can degrade the speed of Bin bag, making Bin bag brittle and decomposed into countless environmentally friendly micro particles in a short time.
