1. Qhov sib txawv ntawm daim ntawv thov.
Qhov ntsuas ntawm kev siv ntawmDaim ntawv PE: siv dav hauv kev lag luam tshuaj lom neeg, tshuab, kev lag luam tshuaj lom neeg, hluav taws xob, khaub ncaws, ntim khoom, khoom noj thiab lwm yam haujlwm. Nws yog siv dav hauv kev thauj mus los roj, kev muab dej, kev tso dej phwj tuaj, kev ywg dej ua liaj ua teb, kev thauj mus los cov khoom me me hauv cov mines, nrog rau cov roj av, kev lag luam tshuaj lom neeg, kev xa ntawv thiab kev sib txuas lus, thiab lwm yam, tshwj xeeb tshaj yog hauv kev thauj mus los roj.
Kev siv ntawm PP phaj: rau cov khoom siv tiv taus kua qaub thiab alkaline, cov khoom siv tiv thaiv ib puag ncig, cov khoom siv tso dej khib nyiab thiab cov pa roj khib nyiab, lub pej thuam txhuam, chav tsis muaj plua plav, cov khoom siv ntawm lub Hoobkas semiconductor thiab nws cov lag luam cuam tshuam, thiab tseem yog cov khoom siv nyiam rau kev ua lub taub dej yas. Thaum lub sijhawm no, PP phaj tuab yog siv dav rau lub phaj stamping, punch pad, thiab lwm yam.
2. Qhov sib txawv ntawm cov yam ntxwv.
PE board yog mos mos thiab muaj qee qhov kev tawv, thiab nws qhov kev tiv thaiv kev cuam tshuam thiab kev ua haujlwm cushioning zoo dua, ntawm cov molded board muaj kev ua tau zoo dua; PP board muaj qhov nyuaj siab, cov khoom siv kho tshuab tsis zoo, qhov tawv tsis tshua muaj thiab kev tiv thaiv kev cuam tshuam tsis zoo.
3. Qhov sib txawv ntawm cov ntaub ntawv.
PP phaj, tseem hu ua polypropylene (PP) phaj, yog cov khoom siv semi-crystalline. Nws nyuaj dua PE thiab muaj qhov melting siab dua. PE daim ntawv yog ib hom thermoplastic resin nrog crystallinity siab thiab tsis polarity. Qhov tsos ntawm HDPE thawj yog dawb milky, thiab nws yog translucent rau qee qhov twg hauv qhov nyias nyias.
