Taw qhia

Lub hnab ntim khoom noj khoom haus yog lub hnab yas sawv ntsug rau tus kheej tsim los ntim khoom noj. Hauv qab ntawm lub hnab yog tsim los nrog cov qauv kev txhawb nqa tshwj xeeb kom lub hnab ntim ruaj khov. Lub hnab ntim khoom noj khoom haus yog ua los ntawm cov ntaub ntawv muaj kev nyab xeeb xws li zaub mov qib PE thiab PET kom ntseeg tau tias lawv tsis muaj tshuaj lom thiab tsis muaj mob thiab tuaj yeem cuam tshuam ncaj qha rau cov zaub mov. Cov hnab ntim khoom noj khoom haus tau siv dav hauv cov khw muag khoom loj, cov khw muag khoom yooj yim, cov khoom noj khoom haus, thiab cov chav ua noj hauv tsev los ntim cov khoom noj txom ncauj, cov khoom npaj rau noj, pob khoom noj, thiab lwm yam khoom noj.

Nta

Ntau yam

Txhawm rau ua kom tau raws li qhov xav tau ntawm kev khaws cia khoom noj, khaws cia, tso saib, thiab nqa, cov hnab ntim khoom noj khoom haus tus kheej feem ntau siv cov txheej txheem ntau txheej. Cov qauv no tuaj yeem hloov kho raws li cov yam ntxwv ntawm cov khoom noj thiab kev cia khoom.

1. Moisture-proof muaj nuj nqi

Lub hnab ntim khoom noj nws tus kheej cais cov dej noo los ntawm kev qhia cov txheej txheem dej noo (PE thiab EVOH). PE yog cov khoom siv polymer nrog cov qauv nruj molecular uas tuaj yeem tsim cov khoom thaiv. EVOH yog cov khoom siv polymer copolymerized los ntawm ethylene thiab vinyl cawv. Nws cov qauv molecular muaj ntau pawg hydroxyl, uas tuaj yeem tsim hydrogen bonds nrog dej molecules los tiv thaiv kev nkag mus ntawm cov dej noo. Nws tuaj yeem khaws cov av noo ntawm cov khoom noj tsis haum xws li txiv ntseej thiab txiv hmab txiv ntoo qhuav hauv qab 5%, kom ntseeg tau tias qhov qhuav thiab freshness ntawm cov zaub mov.

2. Anti-oxidation muaj nuj nqi

Nyob rau hauv cov txheej txheem ntawm cov zaub mov txhawb nqa lub hnab, los ntawm kev ntxiv cov tshuaj antioxidants uas tsim nyog, cov pa oxygen hauv lub pob yog absorbed los yog noj, oxidation tus nqi ntawm cov zaub mov yog qeeb, thiab lub txee lub neej yog txuas ntxiv. Tsis tas li ntawd, cov khoom siv roj tshwj xeeb (PVDC, piv txwv li polyvinylidene chloride) kuj siv. Raws li cov khoom siv tiv thaiv siab, cov tshuaj chlorine atoms hauv cov qauv molecular ntawm PVDC tau zoo sib xws los tsim cov slits me me uas tiv thaiv cov dej molecules thiab oxygen molecules los ntawm kev hla. Lub hnab sawv ntsug ua los ntawm cov khoom siv PVDC tuaj yeem txo cov oxidation tus nqi ntawm cov khoom noj oxidized yooj yim xws li nqaij thiab roj ntau dua 50%, yog li ncua lub txee lub neej ntev li 30 hnub.

3. Anti-ultraviolet muaj nuj nqi

Thaum lub sij hawm tsim cov txheej txheem ntawm cov zaub mov sawv ntsug, ib qho tsim nyog tus nqi ntawm ultraviolet absorber yog ntxiv. Thaum cov rays ultraviolet irradiated ntawm cov khoom noj khoom haus sawv ntsug, lub absorber yuav sai sai nqus cov teeb meem rays. Tib lub sijhawm, lub hnab ntim khoom noj kuj tseem siv cov khoom siv tshwj xeeb UV barrier PET (polyethylene terephthalate). Lub nplhaib benzene nyob rau hauv nws cov qauv molecular tuaj yeem nqus tau zoo thiab tawg cov kab hluav taws xob ultraviolet, uas tuaj yeem txo qhov nkag mus ntawm ultraviolet rays ntawm cov zaub mov los ntawm ntau dua 90%, yog li tiv thaiv cov khoom noj siv mis, khoom noj, thiab lwm yam khoom noj uas raug ultraviolet rays los ntawm deterioration vim ultraviolet rays.

Txuag qhov chaw

Cov hnab ntim khoom noj tuaj yeem sawv ntawm lawv tus kheej hauv cov khw muag khoom xws li cov khw muag khoom loj thiab cov khw muag khoom yooj yim, tsis muaj qhov chaw ntxiv hauv qab txee, uas txhim kho qhov chaw ntsug siv ntawm cov txee. Hauv kev cia khoom hauv tsev, cov yam ntxwv ntawm cov khoom noj khoom haus sawv ntsug ua kom cov khoom ntim tau zoo, txo qhov chaw pov tseg los ntawm kev sib tsoo, thiab qhov chaw siv cov khoom siv ntawm cov khoom siv khoom noj khoom haus sawv ntsug tau nce li 15%. Thaum lub sij hawm kev thauj mus los, lub upright qauv ntawm lub hnab sawv ntsug tso cai rau cov khoom siv qhov chaw ntawm lub tsheb thauj mus los zoo dua, uas tuaj yeem ua rau kom muaj peev xwm ntawm txhua lub tsheb thauj mus los txog li 10%.
