Industry standard for PE water pipes
E 给水管的 材料是聚乙烯，是塑料材料中用量最大的品种，它是由聚乙烯合成的高分子材料。 The material of PE water supply pipe is polyethylene, which is the largest amount of plastic materials. It is a polymer material synthesized from polyethylene. 基本分为两类：低密度聚乙烯 LDPE(强度较低);高密度聚乙烯HDPE。 This material is basically divided into two categories: low density polyethylene LDPE (lower strength); high density polyethylene HDPE. PE materials are divided into five grades according to internationally unified standards: PE32, PE40, PE63, PE80 and PE100.
用于 PE给水 管材 的 是 高密度聚乙烯 HDPE，其等级是PE80、PE100两种(依据最小要求强度MinimumRequired Strength的缩写MRS)。 The high-density polyethylene HDPE is used for PE water supply pipes , and its grades are PE80 and PE100 (according to the Minimum Required Strength Abbreviation MRS). The MRS of PE80 reaches 8MPa; the MRS of PE100 reaches 10MPa. MRS refers to the hoop tensile stress intensity (calculated according to international standards).
PE80 (8.00 ～ 9.99Mpa) is a masterbatch with an antimony trioxide content of 80% on a polyethylene substrate. It can be mainly used in casting and film making at the same time. 掌握 剂量，也被认为是通用母料，颗粒状可自由流动。 It is a granular, free-flowing, dust-free masterbatch. It is safer than traditional powders in the production process, and it is easy to grasp the dosage. It is also considered as a universal masterbatch, and the granules can flow freely.
。 PE100 (10.00 ～ 11.19Mpa) is the number of grades obtained after rounding the minimum required strength (MRS) of polyethylene raw materials. The hydrostatic strength corresponding to 20 ℃, 50 years, and the predicted probability of 97.5% of the material is determined according to GB / T18252. .
The production of PE water supply pipes must be carried out in accordance with this standard.
