PP (polypropylene) yog crystalline resin thiab cov neeg sawv cev ntawm cov khoom siv yas. Nrog rau qhov tshwj xeeb lub ntiajteb txawj nqus ntawm 0.9, nws yog qhov hnyav tshaj plaws ntawm cov khoom siv dav dav, thiab muaj cov tshuaj tiv thaiv zoo heev, hydrolysis tsis kam thiab hluav taws xob. Raws li cov yas uas muaj ntau yam kev siv, nws yog dav siv nyob rau hauv ntau yam teb. Zoo li PP Dub Yas Bushing Rau Kev Lag Luam. Polypropylene yog ib qho kev sib xyaw uas tseem muaj qhov zoo rigidity thiab toughness ntawm qhov kub thiab txias. Nws tuaj yeem siv rau hauv chav sterilization. Nws muaj kev hnav zoo, tsis tshua muaj kev sib txhuam coefficient, tsis muaj dej nqus, cov khoom siv hluav taws xob zoo, nws yooj yim heev, tshuaj lom neeg ua haujlwm zoo, tsis muaj kev sib tsoo hauv kev ntxhov siab. Polypropylene kuj yog cov khoom siv uas tsis tshua muaj siab thiab siab gloss. Polypropylene muaj lub zog tensile siab tshaj plaws ntawm cov khoom olefin. Polypropylene muaj lub siab tensile coefficient tab sis kuj tsis muaj zog tiv thaiv. Polypropylene muaj kev qaug zog zoo, hnav tsis kam, thiab coefficient qis heev ntawm kev sib txhuam piv rau nylon. Txawm li cas los xij, nylon muaj nws tus kheej lubricity, yog li kev puas tsuaj kuj tseem zoo dua li polypropylene. Polypropylene muaj cov tshuaj tiv thaiv zoo heev thiab tiv taus cov kua qaub, cov kua qaub (tshwj tsis yog oxidizing acid), alkali, cawv, tshuaj ntxuav tes thiab dej. Polypropylene tiv taus cov tshuaj tsw qab hydrocarbon, cov tshuaj chlorine, roj thiab roj av ntawm chav tsev kub ntawm 140 ° F. Tsis ntev los no, PVC (polyvinyl chloride) muaj teeb meem vim kev tsim cov dioxins, ntau qhov chaw siv polypropylene es tsis txhob PVC polyvinyl chloride.
OurPP Dub Yas Bushing Rau Kev Lag Luam tuaj yeem siv ntau qhov chaw. Nws kuj tuaj yeem ua rau koj xav tau.
