Ntau tus neeg tsis paub cov khoom siv dab tsicov hnab ntim khoom nojfeem ntau yog ua los ntawm.Honest yuav piav luv luv txog cov ntaub ntawv ntawmhnab ntim khoom nojs.
Cov khoom ntim khoom noj: PVDC (polyvinylidene chloride), PE (polyethylene), PP (polypropylene), PA (nylon), EVOH (ethylene / vinyl cawv copolymer), aluminized zaj duab xis (aluminium + PE), thiab lwm yam, ob peb daim nyias nyias.
Kev tsim cov yeeb yaj kiab tuaj yeem muab faib ua: zaj duab xis ncab, cua tshuab.
Tam sim no, cov ntaub ntawv tseem ceeb siv rau ntim khoom noj yog PP thiab PE, uas yog, polypropylene thiab polyethylene yas.Rau ob qho khoom siv, ntim khoom noj tuaj yeem txaus siab.
Piv nrog rau cov ntim khoom tsis yog khoom noj, PP thiab PE tsis muaj cov khoom siv yas ntxiv.Peb txhua tus paub tias cov khoom siv yas muaj kev cuam tshuam loj heev rau tib neeg lub cev, tshwj xeeb tshaj yog menyuam yaus kev noj qab haus huv.PP thiab PE yuav tsis tso cov khoom lom thaum siv.Lwm cov ntaub ntawv tuaj yeem ua rau mob qog noj ntshav, tab sis PP thiab PE tsis ua.PVC ntim khoom siv los siv rau cov yeeb yaj kiab cling, tab sis vim nws qhov kev ruaj ntseg, nws maj mam hloov los ntawm PE cling zaj duab xis.
Cov yam ntxwv ntawm PE yog: mos, cov khoom siv kho tshuab tsis zoo dua li PP, cov khoom sawv cev muaj xws li cov khw muag khoom loj, hnab yas, hnab khib nyiab, thiab lwm yam. PP yog tawv, anisotropic (nws yog ib qho yooj yim los tsim kua muag yog tias muaj qhov sib txawv), zoo mechanical cov khoom, thiab kev kub siab ua haujlwm zoo dua PE, uas txhais tau hais tias cov khoom muaj lub hnab cij.
Feem ntau raws li cov khoom siv, txheej sab hauv yog PE lossis CPP, txheej txheej yog PA, PET, nruab nrab yuav yog EVOH lossis PVDC, thiab lwm yam, thiab qee qhov yog aluminized zaj duab xis lossis aluminium ntawv ci.
PE thiab CPP muaj cov khoom zoo thaum tshav kub kub sealing, uas yog, lawv yooj yim rau sealing.
PA thiab PET muaj peev xwm luam tau zoo thiab tuaj yeem siv rau hauv txheej txheej los luam cov duab zoo nkauj.
PVDC thiab EVOH muaj cov khoom thaiv zoo thiab tiv thaiv oxidation.
Aluminized zaj duab xis thiab aluminium ntawv ci muaj lub teeb pom kev zoo thiab tsim nyog rau cov khoom uas tsis haum rau lub teeb.
Ntau yam ntaub ntawv muaj cov khoom sib txawv thiab siv sib txawv.Cov hnab ntim khoom noj dav dav tsis yog ib qho khoom siv, tab sis yog cov txheej txheem ntau txheej, uas tuaj yeem ua ke nrog ob txheej, peb txheej, plaub txheej, thiab lwm yam.
Zaub mov qhuavthiabkhoom noj khovFeem ntau yog ua los ntawm PET / PE.
Piv txwv li,ua noj kubfeem ntau yog ua los ntawm nylon composite CPP, los yog lwm yam composites.
Lub casing liab ntawm cov nqaij npua yog ib qho khoom siv PVDC.
Khoom qab zib thiab chocolateFeem ntau siv cov ntawv pob tshab / PP, kraft ntawv / PE / AL / PE, AL / PE, thiab lwm yam.
