1, qhov sib txawv ntawm kev thov.
Kev siv scale ntawmPE daim ntawv: dav siv hauv kev lag luam tshuaj, tshuab, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, khaub ncaws, ntim, khoom noj thiab lwm yam lag luam. Nws yog dav siv hauv kev thauj mus los roj, dej, dej phwj tuaj, kev ua liaj ua teb irrigation, mine nplua particle khoom thauj, roj teb, tshuaj lom neeg kev lag luam, post thiab telecommunications thiab lwm yam kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov roj tsheb thauj mus los.
Scope ntawm kev sivpp paj: acid thiab alkali resistant khoom, ib puag ncig tiv thaiv cov khoom, dej khib nyiab, pov tseg gas discharge khoom, scrubbing ntauwd, huv chav tsev, khoom siv rau semiconductor factories thiab lwm yam industries, thiab kuj yog cov nyiam cov khoom siv los ua cov yas dej tso tsheb hlau luam, cov PP tuab nplooj yog dav siv rau stamping phaj, punch backing phaj, thiab lwm yam.
2. Qhov txawv ntawm cov yam ntxwv.
PE boardyog qhov muag muag, muaj qee qhov kev toughness, zoo dua kev tiv thaiv thiab cushioning kev ua tau zoo, thiab kev ua haujlwm ntawm lub rooj tsavxwm molded zoo dua; PP pawg thawj coj saib muaj zog hardness, tsis zoo txhua yam khoom, tsis tshua muaj toughness, thiab tsis zoo cuam tshuam thiab cushioning.
3. Qhov sib txawv ntawm cov khoom siv.
PP pawg thawj coj saib, tseem hu ua polypropylene (PP) daim ntawv, yog cov khoom siv semi-crystalline. Nws yog ib qho nyuaj thiab muaj qhov melting point ntau dua li PE. PE daim ntawv yog cov crystalline heev, uas tsis yog-polar thermoplastic resin. Cov tsos ntawm thawj HDPE yog milky dawb, thiab cov seem nyias yog translucent rau qee yam.
