PPR yog cov lus luv ntawm lus Askiv Polypropylene-Random. Nquag hu ua Hom III polypropylene. PPR cov yeeb nkab yog cov khoom hloov kho tshiab ntawm UPVC cov xa dej xa, cov yeeb nkab yas yas, PE yeeb, PE-X yeeb thiab PE-RT yeeb. Vim tias nws siv cov tshuab luam ntawv (random copolymerization) thev naus laus zis, lub zog thiab qhov kub siab tsis kam ntawm polypropylene zoo lav, yog li ua lub zog loj ntawm cov khoom siv yeeb nkab.
1. Kev tu huv, kev noj qab haus huv thiab kev tiv thaiv ib puag ncig. Polypropylene yog cov khoom siv rau ib puag ncig thiab siv tau rau kev thauj mus los ntawm dej haus.
2. Cov pob qij txha txuas nrog los ntawm kub yaj kom tsim tag nrho lub cev yam tsis muaj paim quav. Lwm cov ntaub ntawv sib txuas nrog cov kab lo lo ntxhuav, uas muaj qhov tsis zoo thiab zam kev muaj peev xwm ntawm cov kua nplaum.
