Industry standards for PE farm irrigation pipes

E 农田灌溉管 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 field irrigation pipe is polyethylene, which is the most widely used variety of plastic materials. It is a polymer material synthesized from polyethylene. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE farm irrigation pipes must withstand a certain pressure, and usually PE resins with large molecular weight and good mechanical properties, such as HDPE resins, are used. 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 农田灌溉管材 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)。 For PE farmland irrigation pipes , high-density polyethylene ( HDPE) is used. Its grades are PE80 and PE100 (based on the minimum required strength, 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% is determined according to GB / T18252 .

The production of PE farmland irrigation pipes must follow this standard.
