Daim ntawv thov tseem ceeb ntawm lub tshuab nqus tsev ntim hnab yog nyob rau hauv cov khoom noj khoom haus, thiab nws yog siv nyob rau hauv ntau yam khoom noj uas yuav tsum tau muab khaws cia rau hauv ib qho chaw nqus tsev vacuum. Nws yog siv los rho tawm huab cua los ntawm cov hnab yas, thiab tom qab ntawd ntxiv nitrogen lossis lwm cov roj sib xyaw uas tsis muaj teeb meem rau zaub mov.
1. Tiv thaiv kev loj hlob ntawm cov kab mob hauv lub tshuab nqus tsev, tsis txhob muaj cov pa phem ntawm ib puag ncig ib puag ncig, txo cov oxidation ntawm cov roj hauv cov zaub mov, thiab inhibit qhov kev loj hlob ntawm cov kab mob enzyme uas twb muaj lawm.
2. Lub hnab ntim lub tshuab nqus tsev tuaj yeem tiv thaiv cov khoom noj kom tsis txhob ya raws, txo cov dej tsis zoo thiab tswj cov khoom zoo.
3. Kev zoo nkauj ntawm lub tshuab nqus tsev ntim lub hnab nws tus kheej ua rau nws yooj yim rau cov neeg kom muaj kev nkag siab zoo txog cov khoom thiab ua rau muaj kev xav yuav.
Cia peb tham txog cov kev xaiv tshwj xeeb ntawm lub tshuab nqus tsev ntim lub hnab, thiab kev xaiv ntawm ntau hom ntawm lub tshuab nqus tsev ntim hnab yog txawv.
Cov khoom siv PE: haum rau cov hnab ntim khoom ntim qis. Ntau ntim rau cov khoom khov.
Cov khoom siv PA: zoo yoog raws thiab siab puncture tsis kam.
Cov khoom siv PET: nce lub zog ntawm cov khoom ntim khoom, thiab tus nqi qis dua.
Cov khoom siv AL: AL yog aluminium ntawv ci, uas muaj cov khoom thaiv siab, shading zog, thiab ya raws.
PVA khoom: nce barrier zog, siab barrier txheej.
RCPP cov ntaub ntawv: cov khoom siv dav tshaj plaws rau cov hnab ua noj ua haus kub, haum rau kev siv kub.
Lub hnab ntim lub tshuab nqus tsev yog ua los ntawm polyvinylidene chloride, polyester, thiab polyamide cov ntaub ntawv uas muaj kev tiv thaiv oxidative, uas yog, tiv thaiv oxygen permeability thiab zoo shrinkage; Qee qhov ntawm lawv yuav raug suav nrog nylon, polyester zaj duab xis thiab polyethylene cov ntaub ntawv ntau txheej. Cov khoom siv polyvinylidene chloride tau hais los saum toj no yog hom zaj duab xis uas muaj cov txiaj ntsig zoo tshaj plaws ntawm kev thaiv cov pa oxygen thiab dej vapor, tab sis nws yog qhov tseeb tsis tiv taus cua sov sealing. Polyester muaj zog tensile zoo. Nylon muaj cov khoom tiv thaiv cov pa oxygen zoo thiab cov cua kub zoo, tab sis cov dej vapor kis tau tus nqi loj heev thiab cov nqi tsim khoom yog siab. Yog li ntawd, feem ntau, manufacturers feem ntau yuav xaiv cov ntaub ntawv sib xyaw los xaiv qhov zoo thiab qhov tsis zoo ntawm ntau cov yeeb yaj kiab. Yog li ntawd, thaum ntau tus neeg siv khoom siv thiab xaiv lub tshuab nqus tsev ntim hnab, peb yuav tsum txheeb xyuas cov yam ntxwv ntawm cov khoom thiab xaiv cov khoom tsim nyog raws li lawv cov yam ntxwv.
