In many materials, some people often can't distinguish similar materials, such as stretch film and protective film, many people can't distinguish them, and often confuse the two, let's talk about the difference between them today.
Feem ntau, cov yeeb yaj kiab ncab tau ntim nrog cov nplaum nplaum xws li PIB masterbatches. Nws yog machined los ntawm casting thiab muaj ib tug me ntsis nplaum nto uas yuav lo rau nws tus kheej.
Stretch zaj duab xis:
Nws yog tsuas yog siv los qhwv cov khoom thiab ua lub luag haujlwm ruaj khov. Muaj ntau ntau hom kev tiv thaiv zaj duab xis, feem ntau yog cov txheej txheej ntawm cov kua nplaum rau ntawm qhov chaw ntawm lub tshuab cua polyethylene, ib yam li Scotch daim kab xev hauv lub neej txhua hnub.
Feem ntau yog siv los tiv thaiv cov khoom nto. Nws tuaj yeem raug tshem tawm thaum tsis siv. Nyob rau hauv luv luv, stretch zaj duab xis yog tus kheej - nplaum thiab tiv thaiv zaj duab xis yog ib txheej ntawm kua nplaum rau ntawm qhov chaw ntawm zaj duab xis. Cov zaj duab xis stretch yog zoo ib yam li cov yas qhwv peb feem ntau siv, tab sis qhov txawv yog tias nws yog siv rau kev lag luam, thiab cov ntaub qhwv yas yog rau cov khoom noj.
Zaj duab xis tiv thaiv:
Nws yog pob tshab, elastic, tsis yog - tshuaj lom thiab tsis muaj teeb meem mos polyethylene yas zaj duab xis, uas ua raws li thoob ntiaj teb kev tiv thaiv ib puag ncig thiab cov qauv kev nyiam huv. Vertical thiab kab rov tav bidirectional txias stretching yog ua tau yam tsis muaj cua sov. Nws tuaj yeem ua tus kheej - nplaum ntim ntau yam khoom thiab ua kom cov khoom nruj nreem los ntawm kev xoob mus ntev. Nws muaj lub zog siab, siab elastic nro, thiab tuaj yeem nruj nreem qhwv txhua yam ntawm cov khoom, tag nrho pob.
Dab tsi yog qhov txawv ntawm stretch film thiab tiv thaiv zaj duab xis?
1. Cov khoom siv yog tib yam, tab sis cov txheej txheem sib txawv:
Cov zaj duab xis stretch yog ua los ntawm polyethylene, uas muaj zoo toughness thiab tsis yooj yim rau crushed los ntawm zoo tib yam yas crushers, thaum lub ntsiab ntawm cov khoom siv tiv thaiv zaj duab xis yog ethylene, uas yog tsim los ntawm polymerization. Raws li cov khoom sib txawv thiab cov khoom siv yas siv, cov yeeb yaj kiab tiv thaiv tuaj yeem muab faib ua ntau hom thiab haum rau ntau hom sijhawm.
2. Kev siv sib txawv:
Stretch zaj duab xis yog tsuas yog siv rau kev muag khoom thiab kev thauj mus los ntawm cawv, cov zaub mov kaus poom, dej ntxhia, ntau yam dej haus, ntaub, tsis yog - zaub mov, ntim tshuaj thiab lwm yam khoom, thaum cov yeeb yaj kiab tiv thaiv feem ntau yog siv rau microwave cua sov, tub yees. kev khaws cia zaub mov, ntim zaub mov tshiab Thiab lwm lub sijhawm, hauv tsev neeg lub neej, khw muag khoom, tsev so thiab kev lag luam tsim khoom ntim khoom noj.
3. Qhov pib ntawm kev tiv thaiv ib puag ncig yog txawv:
Stretch zaj duab xis cov ntaub ntawv PE tuaj yeem txo cov pa phem, pov tseg pov tseg, rov ua dua thiab tag nrho cov nqi ntim khoom, thaum qee qhov kev tiv thaiv zaj duab xis manufacturers siv cov khoom siv PVC. Cov plasticizer no tuaj yeem nkag los ntawm cov yas qhwv rau hauv cov khoom noj uas muaj roj ntau hauv chav sov, ua rau muaj kev puas tsuaj loj rau tib neeg endocrine system.
Qhov sib txawv ntawm cov zaj duab xis stretch saum toj no thiab cov yeeb yaj kiab tiv thaiv tau muab faib rau ntawm no. Thaum koj xaiv cov yeeb yaj kiab stretch thiab cov yeeb yaj kiab tiv thaiv, koj yuav tsum saib kom meej. Qhov tseeb, lawv kuj txawv heev.
