How to choose PE water supply pipe?

PE给水 道主要有两种,全新料 给水 PE 管和有 回收 给水 PE 管, 区别在于: 第一,全新料 给水 PE 管道无毒、卫生,它的原料分子只有碳、氢元素,没有有害有毒的元素存在。 At present, there are mainly two types of PE water supply pipes in the market . The new material water supply PE pipe and the recycled material water supply PE pipe. The differences are: First, the new material water supply PE pipe is non-toxic and hygienic. Element, no harmful and toxic element exists. 料的 PE给水 道可能气化 部份添加剂会干扰生物内分泌 (影响生殖机能), 甚至 可增加致癌风险,用于排水管道还可以,但用于给水管道是万万不能的 PE water supply pipelines with recycled materials may gasify , some additives will interfere with biological endocrine (affect reproductive function), and even increase the risk of carcinogenesis. It can also be used for drainage pipelines, but it cannot be used for water supply pipelines. . PE 是塑料回收市场增长最快的一部分。 HD PE is the fastest growing segment of the plastic recycling market. 小限度的降解特性和其在包装用途的大量应用。 This is mainly due to its ease of reprocessing, its limited degradation properties, and its large number of applications in packaging applications. PE 经再加工后用于制造不与食物接触的瓶子。 The main recycling is to reprocess 25% of recycled materials, such as post-consumer recycled materials (PCR), with HD PE to make bottles that are not in contact with food.

How to distinguish between the two materials? First, observe the surface finish of the pipe. Generally, impurities such as dust will be mixed in the recycled material, and the surface will be granular, with uneven wall thickness . Second, PE给水管材切口光滑,柔韧度高,第三,可以用专业仪器 检测,全新料 PE管材抗压性、延展性等都有优于添加回收料的PE管材,后者碳酸钙比例要高于前者。 You can use a knife to cut the end face. The recycled material is relatively brittle, and the cut material is not flexible and smooth. The new PE water supply pipe has a smooth cut and high flexibility. Third, you can use professional equipment to test . The ductility is better than PE pipes with recycled materials, the latter has a higher calcium carbonate ratio than the former.

Therefore , pay attention to the selection of PE water supply pipes in order to prevent the use of effects.
