塑料袋原料知識你知道多少?
What do you know about plastic bag raw materials?
塑料袋,可謂是一項令人又愛又恨的發(fā)明,因為塑料袋的使用為人們提供了非常大的便利,但同時,塑料袋又是污染環(huán)境的一大殺器,因為它一旦生產(chǎn)出來就很難自然降解。塑料袋到底是怎么生產(chǎn)的呢?接下來塑料袋生產(chǎn)廠家就給大家介紹一下它的原料知識。
Plastic bags can be described as a love hate invention, because the use of plastic bags provides great convenience for people, but at the same time, plastic bags are a big killer of polluting the environment, because once they are produced, they are difficult to degrade naturally. How are plastic bags produced? Next, the plastic bag manufacturer will introduce its raw material knowledge to you.
塑料袋的原材料是塑料,塑料是從石油或煤炭中提取的化學(xué)石油產(chǎn)品,它是一種很輕的物質(zhì),用很低的溫度加熱就能使它變軟,隨心所欲地做成各種形狀的東西。用它制成的塑料袋色彩鮮艷,重量輕,不怕摔,經(jīng)濟(jì)耐用,它的使用不僅給人們的生活帶來了諸多方便,也很大程度上推動了工業(yè)的發(fā)展。
The raw material of plastic bag is plastic. Plastic is a chemical petroleum product extracted from oil or coal. It is a very light substance. Heating at a very low temperature can make it soft and make things of various shapes at will. The plastic bag made of it has bright color, light weight, no fear of falling, economy and durability. Its use not only brings a lot of convenience to people's life, but also promotes the development of industry to a great extent.
塑料袋在制造生產(chǎn)過程中往往要加入各種物質(zhì)。其中高分子聚合物是塑料的主要成分。此外,為了改進(jìn)塑料的性能,還要在聚合物中添加各種輔助材料。合成樹脂在塑料中的含量一般在40~100,樹脂的性質(zhì)決定了塑料的性質(zhì)。填充劑可以提高塑料的強(qiáng)度和耐熱性能,并降低成本。增塑劑可增加塑料的可塑性和柔軟性,降低脆性,使塑料易于加工成型。
Various substances are often added to plastic bags in the manufacturing process. High polymer is the main component of plastics. In addition, in order to improve the properties of plastics, various auxiliary materials should be added to the polymer. The content of synthetic resin in plastics is generally 40 ~ 100. The properties of resin determine the properties of plastics. Fillers can improve the strength and heat resistance of plastics and reduce costs. Plasticizers can increase the plasticity and softness of plastics, reduce brittleness and make plastics easy to process and shape.
由于塑料袋所造成的環(huán)境危害是巨大的,世界上各個都陸陸續(xù)續(xù)地頒布了相關(guān)的塑料袋管理法令,也在其中。限塑令中規(guī)定了塑料袋的生產(chǎn)標(biāo)準(zhǔn),禁止生產(chǎn)銷售厚度小于0.025毫米的超薄塑料袋。塑料袋的厚度是以絲為單位,一絲就是0.01毫米。我們?nèi)粘I钪谐S玫乃芰洗话闶请p層5絲、單層12絲和雙層7絲,標(biāo)準(zhǔn)要求是塑料袋的厚度是雙層5絲的厚度,若小于這個厚度則為劣質(zhì)的不合格塑料袋。
As the environmental harm caused by plastic bags is huge, all countries in the world have successively promulgated relevant plastic bag management laws, including China. The plastic restriction order stipulates the production standards of plastic bags and prohibits the production and sales of ultra-thin plastic bags with a thickness of less than 0.025 mm. The thickness of the plastic bag is in silk, and one silk is 0.01 mm. The commonly used plastic bags in our daily life are generally double-layer 5 silk, single-layer 12 silk and double-layer 7 silk. The national standard requires that the thickness of the plastic bag is the thickness of double-layer 5 silk. If it is less than this thickness, it is an inferior unqualified plastic bag.
了解了塑料袋的相關(guān)原料知識,日后若是購買塑料袋,一定要選購符合標(biāo)準(zhǔn)的質(zhì)量合格的塑料袋,塑料袋生產(chǎn)廠家也應(yīng)該遵守塑料袋生產(chǎn)標(biāo)準(zhǔn),生產(chǎn)合格的塑料袋。
After knowing the relevant raw material knowledge of plastic bags, if you buy plastic bags in the future, you must buy qualified plastic bags that meet the standards. Plastic bag manufacturers should also abide by the plastic bag production standards and produce qualified plastic bags.
