Qhov tseeb, raws li cov ntaub ntawv sib txawv siv, muaj plaub hom kev ntim dej haus ntawm lub khw: polyester fwj (PET), hlau, ntawv ntim thiab iav fwj, uas tau dhau los ua "plaub tsev neeg loj" hauv khw ntim dej haus. . Los ntawm kev xav ntawm tsev neeg txoj kev lag luam sib koom, iav fwj suav txog li 30%, PET nyiaj rau 30%, hlau nyiaj rau ze li ntawm 30%, thiab cov ntawv ntim nyiaj txog li 10%.
Iav yog qhov qub tshaj plaws ntawm plaub tsev neeg loj thiab tseem yog cov khoom ntim nrog cov keeb kwm ntev tshaj plaws ntawm kev siv. Txhua tus neeg yuav tsum muaj lub tswv yim tias nyob rau xyoo 1980 thiab 1990s, dej qab zib, npias, thiab champagne peb haus tau tag nrho ntim rau hauv khob fwj. Txawm tias tam sim no, iav tseem ua lub luag haujlwm tseem ceeb hauv kev lag luam ntim khoom.
Cov thawv iav tsis muaj tshuaj lom thiab tsis qab, thiab lawv saib pob tshab, tso cai rau tib neeg pom cov ntsiab lus ntawm ib nrais muag, ua rau tib neeg muaj kev zoo nkauj. Tsis tas li ntawd, nws muaj cov khoom thaiv zoo thiab yog airtight, yog li tsis tas yuav txhawj xeeb txog kev nchuav los yog kab nkag mus tom qab tau tawm mus ntev. Tsis tas li ntawd, nws yog pheej yig, tuaj yeem ntxuav thiab tshuaj tua kab mob ntau zaus, thiab tsis ntshai ntawm tshav kub lossis kub siab. Nws muaj ntau txhiab qhov zoo, yog li nws tau siv los ntawm ntau lub tuam txhab khoom noj los tuav cov dej haus. Nws yog tshwj xeeb tshaj yog tsis ntshai ntawm kev kub siab, thiab yog heev haum rau carbonated dej haus, xws li npias, dej qab zib, thiab kua txiv hmab txiv ntoo.
Txawm li cas los xij, iav ntim ntim kuj muaj qee qhov tsis zoo. Qhov teeb meem tseem ceeb yog lawv hnyav, nkig, thiab yooj yim tawg. Tsis tas li ntawd, nws tsis yooj yim rau luam tawm cov qauv tshiab, cov cim, thiab lwm yam kev ua haujlwm thib ob, yog li kev siv tam sim no tau txais tsawg dua. Niaj hnub no, cov dej haus uas ua los ntawm cov iav ntim yog qhov yooj yim tsis pom ntawm cov txee ntawm cov khw loj loj. Tsuas yog nyob rau hauv cov chaw uas tsis muaj zog noj xws li tsev kawm ntawv, khw me me, tsev noj mov, thiab cov khw noj mov me tuaj yeem pom cov dej haus, npias, thiab kua mis hauv khob iav.
Nyob rau xyoo 1980, kev ntim khoom hlau pib tshwm rau ntawm theem. Qhov tshwm sim ntawm cov kaus poom hlau dej tau txhim kho tib neeg txoj kev nyob. Tam sim no, cov kaus poom hlau tau muab faib ua ob-thooj poom thiab peb-thooj poom. Cov ntaub ntawv siv rau peb-thooj poom yog feem ntau tin-plated nyias steel daim hlau (tinplate), thiab cov ntaub ntawv siv rau ob-thooj cov kaus poom yog feem ntau aluminium alloy daim hlau. Txij li thaum txhuas cov kaus poom tau zoo dua sealing thiab ductility thiab kuj tseem haum rau qhov kub thiab txias filling, lawv tsim nyog rau cov dej haus uas tsim cov roj, xws li cov dej haus carbonated, npias, thiab lwm yam.
Tam sim no, txhuas cov kaus poom tau siv dav dua li cov kaus poom hlau hauv khw. Ntawm cov kaus poom dej haus uas koj tuaj yeem pom, yuav luag tag nrho yog ntim rau hauv cov kaus poom txhuas.
Muaj ntau qhov zoo ntawm cov kaus poom hlau. Nws tsis yooj yim rau kev tawg, yooj yim nqa, tsis ntshai ntawm qhov kub thiab txias thiab kev kub siab thiab kev hloov pauv ntawm cov av noo, thiab tsis ntshai kev yaig los ntawm cov khoom tsis zoo. Nws muaj cov khoom thaiv zoo heev, lub teeb thiab kev sib cais roj, tuaj yeem tiv thaiv huab cua los ntawm kev nkag mus rau oxidation cov tshuaj tiv thaiv, thiab khaws cov dej haus kom ntev dua.
Ntxiv mus, qhov saum npoo ntawm cov hlau tuaj yeem yog dai kom zoo nkauj, uas yooj yim rau kev kos ntau yam qauv thiab xim. Yog li ntawd, feem ntau cov dej haus hauv cov kaus poom hlau yog cov yeeb yuj thiab cov qauv kuj tseem nplua nuj heev. Thaum kawg, cov kaus poom hlau tau yooj yim rau kev rov ua dua thiab rov siv dua, uas yog ib puag ncig zoo dua.
Txawm li cas los xij, cov thawv ntim hlau kuj muaj lawv qhov tsis zoo. Ntawm qhov tod tes, lawv muaj cov tshuaj lom neeg tsis zoo thiab ntshai ntawm ob qho tib si acids thiab alkalis. High acidity los yog alkalinity muaj zog heev yuav maj mam corrode cov hlau. Ntawm qhov tod tes, yog tias cov txheej txheej sab hauv ntawm cov khoom ntim hlau tsis zoo lossis cov txheej txheem tsis ua raws li tus qauv, qhov saj ntawm cov dej haus yuav hloov.
Cov ntawv ntim ntawv thaum ntxov feem ntau siv cov ntaub ntawv muaj zog heev. Txawm li cas los xij, cov ntaub ntawv ntim cov ntawv ntshiab yog qhov nyuaj rau siv hauv cov dej haus. Cov ntawv ntim khoom siv tam sim no yog yuav luag tag nrho cov ntaub ntawv sib xyaw, xws li Tetra Pak, Combibloc thiab lwm cov thawv ntim ntawv-yas sib xyaw.
PE zaj duab xis lossis aluminium ntawv ci hauv cov ntaub ntawv sib xyaw tuaj yeem zam lub teeb thiab huab cua, thiab yuav tsis cuam tshuam rau saj, yog li nws yog qhov tsim nyog rau lub sij hawm luv luv preservation ntawm cov mis nyuj tshiab, yogurt thiab khaws cia rau lub sij hawm ntev ntawm cov mis nyuj haus, tshuaj yej dej haus. thiab kua txiv. Cov duab suav nrog Tetra Pak hauv ncoo, aseptic square bricks, thiab lwm yam.
Txawm li cas los xij, lub siab tsis kam thiab sealing barrier ntawm cov thawv ntawv-yas composite tsis zoo li cov iav fwj, cov kaus poom hlau thiab cov thawv yas, thiab lawv tsis tuaj yeem ua kom sov thiab ua kom tsis muaj menyuam. Yog li ntawd, thaum lub sij hawm cia, lub thawv ntawv preformed yuav txo nws cov cua sov sealing kev ua tau zoo vim oxidation ntawm PE zaj duab xis, los yog ua tsis sib xws vim creases thiab lwm yam yog vim li cas, ua rau muaj teeb meem ntawm kev nyuaj rau noj lub filling molding tshuab.
