1. Qhov sib txawv ntawm daim ntawv thov.
Scale ntawm kev sivPE daim ntawv: dav siv hauv kev lag luam tshuaj, tshuab, tshuaj lom neeg kev lag luam, hluav taws xob, khaub ncaws, ntim, zaub mov thiab lwm yam haujlwm. Nws yog dav siv hauv kev thauj mus los roj, dej, dej phwj tuaj, dej ua liaj ua teb, kev thauj mus los zoo hauv cov mines, nrog rau cov roj av, tshuaj lom neeg kev lag luam, kev xa ntawv thiab kev sib txuas lus, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv cov roj tsheb thauj mus los.
Kev siv cov nplais ntawm PP phaj: rau cov khoom siv acid-resistant thiab alkaline, cov cuab yeej tiv thaiv ib puag ncig, cov khoom siv dej khib nyiab thiab cov pa khib nyiab pov tseg, txhuam ntauwd, chav tsis muaj plua plav, cov khoom siv ntawm lub Hoobkas semiconductor thiab nws cov kev lag luam cuam tshuam, thiab tseem yog cov khoom siv rau kev ua cov dej yas. Thaum lub sij hawm no, PP tuab phaj yog dav siv rau stamping phaj, punch pad, thiab lwm yam.
2. Qhov txawv ntawm tus yam ntxwv.
PE board yog qhov muag muag thiab muaj qee qhov tawv, thiab nws cov kev cuam tshuam thiab kev ua haujlwm cushioning zoo dua, ntawm cov pwm pwm muaj kev ua haujlwm zoo dua; PP board muaj siab hardness, tsis zoo txhua yam khoom, tsis tshua muaj toughness thiab tsis zoo cuam tshuam tsis kam.
3. Qhov sib txawv ntawm cov khoom siv.
PP phaj, tseem hu ua polypropylene (PP) phaj, yog cov khoom siv semi-crystalline. Nws yog ib qho nyuaj tshaj li PE thiab muaj cov ntsiab lus melting ntau dua. PE daim ntawv yog ib hom thermoplastic resin nrog siab crystallinity thiab tsis-polarity. Cov tsos ntawm thawj HDPE yog milky dawb, thiab nws yog translucent mus rau ib tug tej yam nyob rau hauv lub nyias seem.
