宠物塑料回收的重要性

如今，PET塑料回收是许多国家的重要项目。在大大小小的垃圾回收站，塑料瓶一直是最受欢迎的“垃圾”。很多人一定好奇这些塑料瓶是如何被回收的，回收后又去了哪里。塑料瓶是由什么制成的？今天我们就来看看吧。

Raw materials of plastic bottles

Most of the bottle body is made of polyethylene terephthalate, which is called PET for short. PET plastic is the best choice for making beverage bottles, because it is easy to shape, has good toughness, is impermeable, and is acid and alkali resistant. Compared with traditional glass bottle packaging, it is light in size and has high transparency. Compared with other waste products, disposable plastic bottles are easier to recycle and have a high recycling rate. PET plastic bottles are also easy to separate from other wastes. Most of them are colorless and transparent. They are thermoplastic plastics that are easy to reshape.

Pet plastic recycling method

Plastic bottles are recycled by the plastic recycling line. The recycled plastic bottles will be compressed and packaged first, which is more convenient for transportation. Then the squashed beverage bottle will pass through the plastic recycling crusher and become small pieces of plastic. Then these plastic fragments will be cleaned to remove the soil, labels, dirt, etc. attached to the surface.

然后利用密度差将瓶体和瓶盖分离。因为饮料瓶的瓶盖和瓶身是由不同的塑料制成的。经过一系列的清洁和筛选过程后，剩余的PET塑料碎片将被加热熔化，制成小塑料颗粒。这些粒状塑料可作为生产新塑料制品的原料。

Application of Recycled Plastic Bottles

PET塑料回收设备生产的回收PET塑料片可制成新的包装容器和塑料薄膜。还可制成人造纤维、织物、服装等。回收的塑料瓶最终变成了一件衣服，这听起来可能并不神奇。事实上，它广泛应用于纺织行业。但当制成纤维时，PET一般被称为“聚酯纤维”或“聚酯纤维”。当你听到这两个名字的时候，你会觉得很熟悉。如果你翻看衣服的标签，你就会看到它们。

随着废弃物回收技术的进步，回收的PET塑料通过高温、真空等条件下的深度清洗，可以满足食品包装的清洁级别。因此，废旧饮料瓶可以回收成新的，真正实现循环利用。
