  大多數都是基于合成樹脂。由于塑料種類繁多,也有許多分類方法。根據組分的性質,可分為纖維素塑料、蛋白質塑料和合成樹脂塑料。 塑料是近年來發展迅速的比較重要的材料,它以合成或天然高分子化合物為基本成分,可以在加工過程中成型,而產品比較終可以保持其形狀不變。根據用途,可分為通用塑料和工程塑料。根據塑化和加熱性能的變化,可分為熱塑性塑料和熱固性塑料。比較后一種是比較常見的分類方法。
  Most of them are based on synthetic resin. Because there are many kinds of plastics, there are also many classification methods. According to the properties of the components, they can be divided into cellulose plastics, protein plastics and synthetic resin plastics. Plastics are the most important materials with rapid development in recent years. They are based on synthetic or natural macromolecule compounds. They can be formed in the process of processing, and the final product can keep its shape unchanged. According to its use, it can be divided into general plastics and engineering plastics. According to the change of plasticizing and heating properties, it can be divided into thermoplastic and thermosetting plastics. The last is the most common classification method.
  因為塑料通常重量輕、絕緣、耐腐蝕、耐摩擦、易于加工且美觀,所以它們可以用作結構材料和絕緣材料,所以它們廣泛應用于航空航天、汽車、船舶、機械、化工、建筑和日用品等行業,許多塑料產品已經取代了金屬產品和木制品,可以說無處不在。
  Because plastics are usually light weight, insulating, corrosion-resistant, friction-resistant, easy to process and beautiful, they can be used as structural materials and insulation materials, so they are widely used in aerospace, automobiles, ships, machinery, chemical industry, construction and daily necessities industries, many plastic products have replaced metal products and wood products, can be said to be ubiquitous.

  塑料工業的快速發展也促進了塑料著色技術的發展。塑料著色已成為現代塑料加工的重要組成部分。多彩炫目的塑料產品豐富了市場,美化了我們的環境和生活。據調查,在全部的塑膠制品中約有80%(質量分數)是歷經上色的,這列舉“黑色”塑膠產品占據挺大的占比,例如,人們平時所聞的鋁合金門窗、上排污管道等都以黑色多見,這種商品看起來那麼“白”,列舉很關鍵的1個原因就是使用了“彩票网站代理加盟群”。
  The rapid development of plastic industry has also promoted the development of plastic coloring technology. Plastic coloring has become an important part of modern plastic processing. Colorful and dazzling plastic products enrich the market and beautify our environment and life. According to the survey, about 80% (mass fraction) of all plastic products have been colored, which enumerates that "black" plastic products account for a large proportion. For example, people usually hear of aluminum alloy doors and windows, sewage pipes and so on are mostly black. This commodity looks so "white" and cites one of the key reasons is the use of "fluorescent whitening agent".
