Cov txiaj ntsig thiab kev siv cov kev siv PP casters

1, PP txheej txheem PP yas, tshuaj npe: polypropylene PP yog crystalline polymer. PP yog lub teeb pom kev hauv plastics, qhov ceev yog tsawg tshaj li dej, thiab nws lub tshav kub kub yog 80-100 ° C. Nws tuaj yeem raug hau hauv dej kub npau npau. PP muaj kev nyuab siab zoo ua haujlwm tsis zoo thiab kev khoov siab siab qaug zog, feem ntau hu ua "100 fold glue". Cov khoom PP muaj lub teeb nyob hauv qhov nyhav, zoo hauv toughness thiab chemically resistant. 2, qhov zoo ntawm PP casters Pp tsis muaj tshuaj lom thiab khoom noj khoom haus, cov khoom siv tau zoo dua qub, cov khoom siv zoo dua qub, muaj cov khoom siv hluav taws xob tsis zoo, PP tsis muaj lub tshuab muaj cov roj ntsha, acid acid, alkali, xws li kua qaub thiab alkali muaj cov nyhuv me me. PP log muaj cov yam ntxwv ntawm kev muaj zog, kev muaj zog, kev qaug zog, kev tswj kev nyuaj siab, thiab lwm yam. Nws qhov kev ua haujlwm tsis cuam tshuam los ntawm cov av qeeg. PP log nyhav nyhav dua li lwm lub plastics PP log tau zoo dua yog pheej yig pheej yig 3. Siv qhov chaw ntawm PP casters Tsim kom siv ntau yam ntawm thaj chaw, siv rau hauv kev lag luam, kev lag luam thiab kev xaav, kev tsim khoom thiab lwm yam lag luam; qhov kub ntawm thaj tsam li ntawm -15 ~ 80 ° C
