Kev taw qhia ntawm cov ntaub ntawv siv rau cov hnab ntim khoom nqus tsev
Cov hnab ntim khoom siv nqus tsevnyob rau hauv peb cov zaus siv txhua hnub yog siab heev, ntau tsev neeg yuav siv Lub Tshuab Nqus TsevCov hnab yas uas siv los ntim khoom noj kom ntev lub txee. Cov khoom siv ntawm lub hnab nqus tsev cuam tshuam ncaj qha rau nws qhov kev ua kom tshiab, qhov kev nthuav qhia nqus tsev tom ntej no peb yuav kawm txog cov khoom siv thiab cov yam ntxwv ntawm lub hnab ntim khoom nqus tsev.
Cov khoom siv ntim khoom noj uas siv ntau zaus muaj cov pawg hauv qab no:
1, polyester cov hnab nqus tsev:
Polyester yog ib lo lus dav dav rau cov polymers tau los ntawm polyol thiab polyacid polycondensation. Feem ntau yog hais txog polyethylene terephthalate (PET), polyester (PET) lub hnab nqus tsev nws yog ib lub hnab nqus tsev tsis muaj xim thiab pob tshab, ci ntsa iab, yog ua los ntawm polyethylene terephthalate ua cov khoom siv raw, siv txoj kev extrusion rau hauv daim ntawv tuab, thiab tom qab ntawd los ntawm kev ncab ob-txoj kev ua los ntawm cov khoom siv hnab nqus tsev. Cov khoom siv kho tshuab zoo heev, muaj zog heev, tawv thiab tawv, tiv taus qhov tho, tiv taus kev sib txhuam, tiv taus kub thiab txias siab, tiv taus tshuaj lom neeg, tiv taus roj, tiv taus huab cua thiab khaws cia cov tsw qab zoo, yog ib qho ntawm cov khoom siv feem ntau siv permeability barrier composite hnab nqus tsev substrate. Feem ntau siv los ua txheej sab nraud ntawm cov ntaub ntawv ntim khoom siv steaming, kev ua haujlwm siab zoo dua.
2, nylon lub hnab nqus tsev:
Lub hnab nqus tsev nylon (PA) yog lub hnab nqus tsev uas ruaj khov heev, pob tshab zoo, thiab ci ntsa iab zoo, lub zog tensile siab, kuj tiv taus kub zoo, tiv taus txias, tiv taus roj thiab tiv taus cov organic solvents, tiv taus kev sib txhuam, tiv taus qhov tho qhov zoo heev, thiab mos dua, tiv taus oxygen zoo heev, tsim nyog rau kev ntim cov khoom tawv, xws li cov khoom noj roj, cov khoom nqaij, cov khoom kib, cov khoom noj ntim hauv lub tshuab nqus tsev, cov khoom noj ua noj, thiab lwm yam.
Raws li nylon Lub Hnab Nqus Tsev tuaj yeem muab tau los ntawm cov hnab nylon composite ua tau zoo dua thiab cov hnab nqus tsev ntau txheej co-extruded.
Cov hnab nylon sib xyaw ua ke feem ntau yog tsim los ntawm PET / PE, PVC / PE, NY / PVDC, PE / PVDC, PP / PVDC, qhov sib txawv tseem ceeb ntawm lub hnab sib xyaw ua ke thiab cov txheej txheem feem ntau muaj cov khoom siv substrate, laminating adhesive, barrier materials, heat sealing materials, printing thiab protective coatings thiab lwm yam khoom.
Lub hnab nqus tsev uas muaj ntau txheej sib koom ua ke yog nylon, ua los ntawm PA, EVOH thiab PE, PP, TIE thiab lwm yam resins, siv cov qauv sib xyaw ua ke lossis tsis sib xws. Thaum PA, EVOH koom ua ke, tsis yog tsuas yog txhim kho cov zaj duab xis ntau txheej ntawm cov pa oxygen thiab saj, lub zog tev tawv sib xyaw, kev tiv thaiv ib puag ncig thiab lub sijhawm khaws cia tshiab. Tsis muaj kuab paug, muaj kuab paug siab, muaj zog, pheej yig, muaj peev xwm me me, muaj zog siab, muaj qauv yooj ywm thiab lwm yam, nws ua rau cov txheej txheem tsim khoom noj khoom haus tsis muaj kuab paug.
Polyethylene (polyethylene, luv PE) yog cov thermoplastic resin uas tsim los ntawm kev sib xyaw ua ke ntawm ethylene. Nws pob tshab dua li nylon, tawv, suab nrov, muaj cov yam ntxwv zoo heev ntawm kev thaiv roj, roj thiab tsw qab. Nws tsis haum rau kev siv kub thiab txias, thiab tus nqi pheej yig dua li nylon. Feem ntau siv rau cov khoom siv hauv lub hnab nqus tsev uas tsis muaj kev cai tshwj xeeb.
4, lub hnab nqus tsev aluminium ntawv ci:
Lub hnab nqus tsev ua los ntawm txhuas-yas sib xyaw (PET/AL/PE lossis PET/NY/AL/PE lossis PET/NY/AL/CPP), yog cov khoom tseem ceeb ntawm cov ntawv ci txhuas, tsis pom tseeb, nyiaj-dawb, nrog rau kev tiv thaiv kev ci ntsa iab, nrog kev thaiv zoo, kev kaw cua sov, kev tiv thaiv kev sib hloov, kev tiv thaiv kev kub siab, kev tiv thaiv kub qis, kev tiv thaiv roj, khaws cia tsw qab; tsis muaj tshuaj lom thiab tsis qab; mos thiab lwm yam ntxwv. Haum rau cov tshuab loj thiab cov khoom siv precision, cov ntaub ntawv raw tshuaj, cov tshuaj nruab nrab, cov khoom siv tiv thaiv dej noo, lub teeb, ntim khoom nqus tsev. Ntau tshaj plaub txheej qauv, nrog kev ua haujlwm zoo ntawm dej thiab oxygen. Lub hnab nqus tsev ua los ntawm txhuas ntawv ci yog siv dav hauv cov khoom noj, khoom siv hluav taws xob, tshuaj lom neeg thiab lwm yam lag luam, vim tias cov ntawv ci txhuas nws tus kheej yog cov ntaub ntawv raw kim dua, yog li tus nqi ntawm lub tshuab nqus tsev yuav siab dua.
Qhov saum toj no yog qhov kev ua yeeb yam nqus tsev uas tau muab sau tseg rau ntawm cov hnab ntim khoom nqus tsev Cov ntaub ntawv siv thiab cov yam ntxwv ntawm kev taw qhia, kuv ntseeg tias tom qab nyeem ntau tus phooj ywg hauv kev xaiv lawv cov hnab ntim khoom yuav muaj kev nkag siab dav dav txog nws, xav paub ntau ntxiv, txais tos los sab laj nrog peb.
