Lub tshuab nqus tsev ntim yog hais txog lub tshuab ntim khoom uas cov khoom tau muab tso rau hauv cov thawv ntim, tom qab ntawd cov huab cua hauv cov ntim tau muab rho tawm thiab kaw, tawm hauv cov khoom hauv lub tshuab nqus tsev lossis ib puag ncig hypoxic. Nws lub hauv paus ntsiab lus tseem ceeb yog cais cov pa oxygen, inhibit qhov kev loj hlob thiab kev loj hlob ntawm cov kab mob (xws li cov kab mob thiab cov pwm), thiab txo qis tus nqi ntawm oxidative deterioration ntawm cov khoom, yog li ncua lub txee lub neej ntawm cov khoom thiab khaws cia lawv cov khoom qub. Piv nrog rau kev ntim khoom ib txwm muaj, lub tshuab nqus tsev ntim kuj tuaj yeem txo cov ntim ntim, ua kom yooj yim rau kev ntim khoom thiab kev thauj mus los, thiab tiv thaiv cov khoom los ntawm kev sib kis los ntawm ib puag ncig sab nraud thaum khaws cia. Nws yog ib txoj kev ntim khoom tseem ceeb hauv cov khoom noj, tshuaj, khoom siv hluav taws xob thiab lwm yam lag luam.
Daim ntawv thov teb ntawm lub tshuab nqus tsev ntim yog dav heev, ntawm cov khoom noj khoom haus yog qhov tseem ceeb tshaj plaws ntawm daim ntawv thov scenario. Cov khoom noj xws li nqaij, nqaij nruab deg, zaub mov siav, txiv ntseej thiab nplej tuaj yeem daws tau qhov teeb meem ntawm kev puas tsuaj yooj yim hauv chav tsev kub cia los ntawm lub tshuab nqus tsev ntim khoom. Piv txwv li, lub txee lub neej ntawm chilled tshiab nqaij nrog lub tshuab nqus tsev ntim tuaj yeem txuas ntxiv mus rau 7-15 hnub, deb tshaj li 1-2 hnub ntawm kev muag khoom ntau. Tsis tas li ntawd, hauv kev lag luam kws tshuaj, qee cov tshuaj thiab cov khoom siv kho mob tuaj yeem tiv thaiv los ntawm kev ya raws thiab oxidation los ntawm lub tshuab nqus tsev ntim khoom; nyob rau hauv kev lag luam electronics, precision Cheebtsam yuav zam cov plua plav paug thiab oxidative puas tsuaj los ntawm kev siv lub tshuab nqus tsev ntim; down cov khoom thiab cov khoom siv ntaub plaub nyob rau hauv kev lag luam textile kuj tuaj yeem compressed nyob rau hauv ntim los ntawm lub tshuab nqus tsev ntim, uas yog yooj yim rau kev cia thiab kev thauj mus los.
Cov khoom xaiv ntawm lub tshuab nqus tsev ntim yog nyob ntawm cov yam ntxwv ntawm cov khoom, thiab cov khoom siv feem ntau yog cov yas zaj duab xis. Ntawm lawv, PA / PE zaj duab xis sib xyaw ua ke nrog lub zog siab ntawm nylon thiab cov cua sov- sealing khoom ntawm polyethylene, uas yog tsim rau hnyav ntim xws li nqaij thiab nqaij nruab deg; PET / PE zaj duab xis muaj qhov pom tseeb thiab cov khoom thaiv zoo, uas feem ntau yog siv rau ntim khoom noj txom ncauj thiab zaub mov siav; aluminium foil composite zaj duab xis muaj cov cuab yeej muaj zog heev, uas tuaj yeem sib cais lub teeb, oxygen thiab dej, thiab tsim nyog rau cov khoom uas xav tau ntev - lub sij hawm cia, xws li cov zaub mov hauv kaus poom thiab cov khoom qhuav. Cov ntaub ntawv sib txawv muaj qhov sib txawv ntawm qhov kub thiab txias tsis kam, uas yuav tsum tau ua kom haum rau kev ua thiab kev cia khoom ntawm cov khoom.
Muaj qee cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov thaum siv lub tshuab nqus tsev ntim khoom. Ua ntej tshaj plaws, cov khoom yuav tsum tau qhuav thiab huv si kom tsis txhob ya raws thiab impurities cuam tshuam cov nyhuv sealing; thib ob, qhov chaw tsim nyog yuav tsum tau khaws tseg thaum lub sij hawm ntim khoom kom tsis txhob muaj kev sib tsoo thiab kev puas tsuaj los ntawm kev ua kom adhesion ntau dhau ntawm cov khoom thiab ntim zaj duab xis; thib peb, lub tshuab nqus tsev kawm ntawv yuav tsum tau hloov kho raws li cov khoom, thiab nws tsis yog tias qhov siab dua qhov zoo dua - lub tshuab nqus tsev ntau dhau yuav ua rau muaj kev puas tsuaj rau qee cov khoom muag. Tsis tas li ntawd, lub tshuab nqus tsev ntim tsis yog panacea. Yog tias lub ntim khoom puas lawm los yog cov khoom muaj cov kab mob hauv thawj zaug, qhov kev puas tsuaj tseem tuaj yeem tshwm sim, thiab nws yuav tsum tau siv nrog cov khoom tsim nyog (xws li lub tub yees, chav tsev kub thiab qhuav).
