聚对苯二甲酸乙二醇酯，英文名：polyethylene terephtha
Polyethylene terephthalate, English Name: polyethylene terephtha
late，简称PET，为高聚合物，由对苯二甲酸乙二醇酯发生脱水
Late, referred to as PET, dehydrated ethylene terephthalate for high polymers.
缩合反应而来。
Condensation reaction.
PET 是乳白色或浅黄色、高度结晶的聚合物，表面平滑有
PET is a milky or yellowish, highly crystalline polymer with smooth surface.
光泽。PET桶材质比较软，透明度比较高。
Lustre. PET barrels are soft and transparent.
PET桶曾经在电视中爆出过饮水安全问题。长期饮用PET桶装
PET barrels once reported drinking water safety problems on TV. Long term consumption of PET barreled
水的致癌概率比普通概率高出27%。我国的国家质监局也曾经禁止
The probability of carcinogenesis of water is 27% higher than that of ordinary probability. China's National Quality Supervision Bureau has also banned.
PET材质在水桶中的应用。
Application of PET material in bucket.
PET不耐热，在该材质的桶暴漏在高温或者开水中时候，该种
PET is not heat resistant, when the material bucket is leaking in high temperature or open water.
材质就会受热分解产生出有害的毒素。PET材质应用在水桶中，它
The material will be decomposed by heat and produce harmful toxins. The PET material is used in the bucket.
可以应用在不加热的饮料瓶中。
It can be applied to unheated beverage bottles.
两种桶的分辨方法：
Two ways to distinguish barrels:
1、通过颜色进行判断，颜色比较亮，通透感比较强的是PET材质纯
1, judging by color, the color is lighter, and the penetration is stronger than that of PET material.
净水桶。
Purified Water Bucket.
2、软硬度对比，PC桶材质比较硬，PET桶材质比较软，用手在常力
2, soft hardness contrast, PC barrel material is hard, PET barrel material is soft, hand in constant force.
下进行加压，容易变形的就是PET桶。
The PET barrel is easy to deform under pressure.
3、通过声音判断，PET桶的声音比较脆，用手轻轻一挤，就可以发
3, judging by voice, the voice of PET barrel is crisp, and it can be sent by hand.
生，PC桶材质硬，用手敲，不易变形，并且声音比较闷，呈现淡蓝色。
Raw, PC barrel material hard, hand knock, not easy to deformation, and the voice is boring, showing pale blue.
