Kev piav qhia

PPR Txiv neej Threaded Union yog random copolymer polypropylene synthesized los ntawm cov roj theem txoj kev. Nws cov yam ntxwv tshwj xeeb yog tias cov PE molecules tau sib txuas hauv PP molecules, thiab qhov hnyav molecular li ntawm 300, 000 txog 800, 000. Cov kav dej uas tsim los ntawm kev siv PPR cov ntaub ntawv raw, tseem hu ua random copolymer polypropylene kav, yog cov khoom siv yeeb nkab yas tsim thiab siv rau xyoo 1980s thiab thaum ntxov 1990s. Nrog nws cov kev ua tau zoo heev thiab ntau yam kev siv, nws tau nyob hauv ib qho chaw hauv kev lag luam yeeb nkab yas thiab yog ib qho khoom siv ntsuab thiab ib puag ncig zoo. Txawm li cas los xij, hauv kev lag luam kev lag luam hauv xyoo tas los no, kev soj ntsuam ntawm cov teeb meem saum toj no PPR yas yeeb nkab zoo kuj pom tias muaj ntau yam teeb meem hauv PPR yeeb nkab ua lag luam, thiab cov teeb meem no tau txwv tsis pub muaj kev noj qab haus huv ntawm cov kav dej PPR.
