1, qhov sib txawv ntawm daim ntawv thov.
Qhov ntsuas 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 lag luam. 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 ntawm cov khoom me me, thaj chaw roj, kev lag luam tshuaj lom neeg, kev xa ntawv thiab kev sib txuas lus thiab lwm yam teb, tshwj xeeb tshaj yog hauv kev thauj mus los roj.

Scope ntawm kev siv ntawmdaim ntawv ppCov khoom siv tiv taus kua qaub thiab alkali, cov khoom siv tiv thaiv ib puag ncig, dej khib nyiab, cov khoom siv tso pa roj khib nyiab, lub pej thuam txhuam, chav huv si, cov khoom siv rau cov chaw tsim khoom semiconductor thiab cov lag luam cuam tshuam, thiab tseem yog cov khoom siv nyiam rau kev ua cov thoob dej yas, ntawm cov uas PP cov ntawv tuab siv dav Siv rau stamping phaj, punch backing phaj, thiab lwm yam.

2. Qhov txawv ntawm cov yam ntxwv.

PE pawg thawj coj saib xyuasyog mos muag, muaj qee qib ntawm kev tawv, zoo dua qhov cuam tshuam thiab kev ua haujlwm cushioning, thiab kev ua tau zoo ntawm molded board zoo dua; PP board muaj qhov nyuaj siab, cov khoom siv kho tshuab tsis zoo, tsis tshua muaj zog, thiab tsis zoo cuam tshuam thiab cushioning.

3. Qhov sib txawv ntawm cov ntaub ntawv.

PP pawg thawj coj saib xyuas, tseem hu ua polypropylene (PP) daim ntawv, yog cov khoom siv semi-crystalline. Nws nyuaj dua thiab muaj qhov melting siab dua PE. PE daim ntawv yog cov thermoplastic resin uas muaj crystalline heev, tsis yog polar. Cov tsos ntawm HDPE thawj yog dawb milky, thiab qhov nyias nyias yog translucent rau qee qhov.
