1. Qhov sib txawv ntawm daim ntawv thov.
PE phaj siv nplai: dav siv hauv kev lag luam tshuaj, tshuab, tshuaj lom neeg kev lag luam, hluav taws xob, khaub ncaws, ntim, khoom noj thiab lwm yam haujlwm.Siv dav hauv kev thauj mus los roj, dej, dej phwj tuaj, dej ua liaj ua teb, mining nplua particle khoom thauj mus los, nrog rau cov roj av, tshuaj lom neeg kev lag luam thiab kev xa ntawv thiab kev sib txuas lus, tshwj xeeb tshaj yog nyob rau hauv cov roj tsheb thauj mus los tau dav siv.
Pp phaj siv nplai: cov khoom siv acid thiab alkali tsis kam, cov khoom siv tiv thaiv ib puag ncig, cov dej khib nyiab, cov khoom siv khib nyiab pov tseg, ntxhua khaub ncaws, chav tsev huv, semiconductor Hoobkas thiab lwm yam khoom siv, kuj yog thawj qhov kev xaiv rau kev tsim cov yas dej tank, pp. tuab phaj yog dav siv hauv xuas nrig ntaus phaj, xuas nrig ntaus phaj thiab lwm yam.
2. Qhov txawv ntawm tus yam ntxwv.
PE phaj yog mos, muaj qee yam toughness, cuam tshuam tsis kam thiab kev ua haujlwm tsis zoo, kev ua haujlwm ntawm cov phaj pwm zoo dua;PP board siab hardness, txhua yam khoom tsis zoo, tsis tshua muaj toughness, tsis zoo cuam tshuam tsis zoo.
3. Qhov sib txawv ntawm cov khoom siv.
PP board, tseem hu ua polypropylene (PP) board, yog ib qho khoom siv semi-crystalline.Nws yog ib qho nyuaj tshaj li PE thiab muaj cov ntsiab lus melting ntau dua.PE daim ntawv yog lub siab crystallinity, tsis yog-polar thermoplastic resin.Cov tsos ntawm tus thawj HDPE yog milky dawb, nrog rau ib tug tej degree ntawm translucency nyob rau hauv lub nyias seem.
