Hom hom zaub mov hloov tau ntim cov yeeb yaj kiab

Nyob rau hauv lub ntiaj teb loj ntawm kev ntim khoom noj, muag muagntim zaj duab xis yobtau yeej kev lag luam thoob plaws vim nws lub teeb yuag, zoo nkauj, thiab yooj yim rau kev ua cov yam ntxwv. Txawm li cas los xij, thaum nrhiav kev tsim kho tshiab thiab ntim khoom zoo nkauj, peb feem ntau saib tsis pom kev nkag siab ntawm cov yam ntxwv ntawm cov khoom ntim lawv tus kheej. Niaj hnub no, cia peb nthuav tawm qhov paub tsis meej ntawm cov khoom noj mos ntim zaj duab xis thiab tshawb nrhiav yuav ua li cas kom ua tiav qhov kev nkag siab tsis meej nrog kev luam ntawv substrates hauv ntim qauv tsim, ua kom ntim tau zoo dua.

Cov npe luv thiab cov yam ntxwv sib xws ntawm cov yas

Ua ntej, peb yuav tsum muaj kev nkag siab yooj yim ntawm cov ntaub ntawv yas siv. Hauv cov ntawv ntim khoom noj, cov ntaub ntawv yas muaj xws li PE (polyethylene), PP (polypropylene), PET (polyethylene terephthalate), PA (nylon), thiab lwm yam. Txhua yam khoom muaj nws lub cev thiab tshuaj lom neeg, xws li pob tshab, lub zog, kub. kuj, barrier kev ua tau zoo, thiab lwm yam.

PE (polyethylene): Qhov no yog cov khoom siv yas uas muaj pob tshab thiab yooj yooj yim, txawm tias tus nqi qis. Txawm li cas los xij, nws qhov kub tsis kam yog qhov tsis zoo thiab nws tsis haum rau ntim cov khoom noj uas siav los yog khov ntawm qhov kub thiab txias.
PP (polypropylene): PP cov khoom muaj qhov kub thiab txias thiab tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj deformation, yog li nws feem ntau siv rau hauv cov khoom ntim khoom noj uas yuav tsum tau steamed lossis khov.
PET (polyethylene terephthalate): Cov ntaub ntawv PET muaj cov pob tshab thiab lub zog zoo, nrog rau qhov kub thiab txias tsis kam, yog li lawv feem ntau siv rau hauv cov ntim khoom noj uas xav tau siab pob tshab thiab lub zog.
PA (Nylon): Cov khoom siv PA muaj cov khoom thaiv zoo heev, uas tuaj yeem tiv thaiv kev nkag mus ntawm oxygen thiab dej, thiab tswj cov khoom noj tshiab. Tab sis piv rau lwm cov ntaub ntawv, tus nqi ntawm PA yog siab dua.

Yuav xaiv food cov ntaub ntawv ntim khoom
Tom qab nkag siab txog cov yam ntxwv ntawm ntau yam ntaub ntawv yas, peb tuaj yeem xaiv cov khoom tsim nyog rau kev ntim cov qauv tsim raws li cov yam ntxwv thiab kev xav tau ntawm cov khoom. Nyob rau tib lub sijhawm, thaum xaiv cov ntawv luam ntawv substrates, kev luam ntawv tsim nyog thiab tus nqi ntawm cov ntaub ntawv yuav tsum tau txiav txim siab.

Xaiv cov khoom tsim nyog raws li cov yam ntxwv ntawm cov khoom: piv txwv li, rau cov khoom noj uas yuav tsum tau steamed lossis khov, peb tuaj yeem xaiv PP cov ntaub ntawv uas muaj qhov kub thiab txias; Rau cov khoom uas xav tau siab pob tshab thiab lub zog, peb tuaj yeem xaiv cov khoom siv PET.
Xav txog qhov tsim nyog ntawm kev luam ntawv: Cov ntaub ntawv sib txawv muaj cov kev cai sib txawv rau cov kua nplaum adhesion thiab dryness. Thaum xaiv cov tshuab luam ntawv substrates, peb yuav tsum xav txog qhov tsim nyog ntawm kev luam ntawv ntawm cov ntaub ntawv los xyuas kom meej tias cov luam ntawv zoo nkauj thiab siv tau ntev.
Kev tswj hwm tus nqi: Thaum ntsib cov yam ntxwv ntawm cov khoom lag luam thiab kev luam ntawv tsim nyog, peb kuj yuav tsum tswj cov nqi kom ntau li ntau tau. Piv txwv li, thaum muaj, peb tuaj yeem ua qhov tseem ceeb ntawm cov ntaub ntawv PE nrog cov nqi qis.

Hauv kev xaus, nyob rau hauv lub ntim qauv tsim ntawm cov khoom nojyas ntim zaj duab xis, nws tsis yog tsim nyog kom muaj kev nkag siab zoo ntawm cov ntawv luam tawm, tab sis kev nkag siab yooj yim kuj tseem tsim nyog. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem ua kom muaj kev nyab xeeb thiab tshiab ntawm cov zaub mov thaum tsim cov ntim zoo nkauj thiab siv tau.
