引言

PVC屬于非結(jié)晶型的無定型塑料，通過拉伸取向，使管材中的PVC長鏈分子規(guī)整排列，由于分子

取向后環(huán)向強(qiáng)度的提高，可以降低管材壁厚，節(jié)約材料和能源，可獲得高強(qiáng)度、高韌性、高抗沖、抗疲勞

的新型PVC管材，常稱之為取向硬聚氯乙烯（PVC?O）管。

本文件參考EN17176?1：2019《用于供水和地下、地上排水、排污以及壓力灌溉的塑料管道系統(tǒng)—

取向硬聚氯乙烯（PVC?O）第1部分：總則》、EN17176?2：2019《用于供水和地下、地上排水、排污以及

壓力灌溉的塑料管道系統(tǒng)—取向硬聚氯乙烯（PVC?O）第2部分：管材》和EN17176?3：2019《用于供

水和地下、地上排水、排污以及壓力灌溉的塑料管道系統(tǒng)—取向硬聚氯乙烯（PVC?O）第3部分：管

件》、GB/T41422—2022《壓力輸水用取向硬聚氯乙烯（PVC?O）管材和連接件》編制。

本文件提出的高性能取向硬聚氯乙烯（PVC?O）管材和管件是通過優(yōu)化混配料/配方、生產(chǎn)工藝，整

體性能得到提升。與現(xiàn)行GB/T41422國家標(biāo)準(zhǔn)相比，落錘沖擊的判定標(biāo)準(zhǔn)TIR值從10%提升到

5%；并特別規(guī)定材料定級后，坯管材料的混配料/配方和拉伸比要保持穩(wěn)定，取向因子的允許變化值不

超過制造商給定值的-5%~+15%；材料等級最低值由315級提高到400級，即取消了315級、355級

低材料等級管材；同時，增加了環(huán)向拉伸強(qiáng)度、切口靜液壓強(qiáng)度、耐壓試驗(yàn)、取向因子指標(biāo)要求。
