Muaj ntau ntau hom Nqus Hnab, yuav ua li cas cov neeg siv khoom xaiv cov qauv zoo tshaj plaws ntawm lub hnab ntim khoom.
Vim tias cov khoom sib txawv muaj cov kev xav tau sib txawv ntawm cov khoom ntim, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom raws li cov yam ntxwv ntawm cov khoom, xws li: seb nws puas yooj yim rau deteriorate, yam ua rau deterioration (lub teeb, dej los yog oxygen, thiab lwm yam), cov khoom zoo li. , khoom deg hardness, cia tej yam kev mob, sterilization kub, thiab lwm yam. Lub tshuab nqus tsev ntim zoo tsis tas yuav muaj ntau lub zog, tab sis nws nyob ntawm seb nws puas haum rau cov khoom.
1. Cov khoom lag luam nrog cov duab tsis tu ncua lossis muag muag
Rau cov khoom uas muaj cov duab tsis tu ncua lossis cov chaw mos, xws li cov khoom siv hnyuv ntxwm, cov khoom siv soy, thiab lwm yam, tsis tas yuav tsum tau muab cov kev xav tau siab rau lub zog ntawm cov khoom siv, thiab tsuas yog cov nyhuv ntawm cov khoom thaiv kev tiv thaiv thiab kev ua kom tsis muaj menyuam ntawm qhov kub thiab txias. cov khoom yuav tsum tau txiav txim siab. Yog li ntawd, cov khoom no feem ntau siv OPA / PE cov hnab ntim khoom. Yog tias qhov kub thiab txias kom tsis muaj menyuam (siab dua 100 degree C) yuav tsum tau, OPA / CPP qauv lossis kub resistant PE tuaj yeem siv los ua cov txheej txheem cua sov.
2. Cov khoom uas muaj qhov siab hardness
Xws li cov khoom siv pob txha, vim muaj qhov tawv tawv thiab tawv tawv, lub tshuab nqus tsev thiab lub hnab ntim tau yooj yim thaum lub sijhawm thauj mus los, yog li lub ntim ntawm cov khoom zoo li no yuav tsum muaj kev sib tsoo zoo thiab kev ua haujlwm buffering, Nqus Pob ntawm PET / PA / PE lossis OPET OPA /CPP muaj. Yog tias cov khoom hnyav tsawg dua 500g, koj tuaj yeem sim OPA / OPA / PE lub hnab ntim khoom, cov khoom lag luam muaj qhov hloov tau zoo, zoo nqus cov nyhuv, thiab tsis hloov cov duab ntawm cov khoom.
3. Cov khoom puas tsuaj
Cov khoom uas kub kub thiab lwm yam khoom, nws yog ib qho yooj yim rau deteriorate, xav tau tsis muaj kub sterilization, lub zog ntawm lub hnab ntim tsis siab, tab sis nws yuav tsum tau zoo barrier zog, yog li koj muaj peev xwm xaiv co-extruded zaj duab xis yob, xws li PA. / PE / EVOH zaj duab xis yob, PA / PE qauv kuj tuaj yeem ua ke nrog lwm cov ntaub ntawv ntawm zaj duab xis, PA / PE zaj duab xis, lossis txhuas plating thiab lwm yam ntaub ntawv. Rau cov khoom kub kub, PVDC shrink hnab los yog lub hnab qhuav tuaj yeem siv.
4. Cov khoom zoo dua
Xya-txheej thiab cuaj-txheej co-extruded ntim, nws cov kev ua haujlwm tsis zoo yog qhov zoo dua, tuaj yeem ua tau raws li cov kev xav tau ntawm 1, 2, 3 cov khoom, nws siv ua rau koj cov khoom muaj qib siab dua, ua kom lub neej ntev ntawm cov khoom.
