Hauv thaj tsam ntawm qhov hnyav-dawb laminating, qhov kub thiab txias retorting yog ib qho teeb meem nyuaj nyob rau ob peb xyoos dhau los.Thaum nrog rau kev txhim kho cov khoom siv, cov nplaum thiab cov thev naus laus zis, hnyav-dawb laminating rau cov yas nrog cov yas hauv qab 121 ℃ retorting tau txais ntau daim ntawv thov ntawm cov khoom lag luam ntim tau yooj yim.Dab tsi ntxiv, tus naj npawb ntawm cov chaw tsim khoom uas ntiav PET / AL, AL / PA thiab Yas / AL rau 121 ℃ retorting yog loj hlob.
Daim ntawv no yuav tsom mus rau kev txhim kho tshiab, tswj cov ntsiab lus thaum tsim khoom thiab cov qauv yav tom ntej.
1. Kev tsim kho tshiab kawg
Retorting pouches tam sim no muab faib ua ob hom substrates, yas / yas thiab yas / txhuas.Raws li GB / T10004-2008 yuav tsum tau, retorting txheej txheem yog cais raws li ib nrab-siab kub (100 ℃ - 121 ℃) thiab siab kub (121 ℃ - 145 ℃) ob tug qauv.Tam sim no, hnyav-dawb laminating tau npog 121 ℃ thiab qis dua 121 ℃ sterilization kho.
Tsuas yog cov ntaub ntawv paub txog PET, AL, PA, RCPP, uas yog siv rau peb lossis plaub txheej laminates, qee cov ntaub ntawv xws li pob tshab aluminized films, retorting PVC tshwm hauv khw.Txawm hais tias tsis muaj kev tsim khoom loj thiab kev siv, cov ntaub ntawv no xav tau ntau lub sijhawm thiab kev sim ntau dua rau kev siv loj.
Tam sim no, peb cov nplaum WD8262A / B tau ua tiav cov ntaub ntawv thov ntawm substrate PET / AL / PA / RCPP, uas tuaj yeem ncav cuag 121 ℃ retorting.Rau cov yas / yas substrate PA / RCPP, peb cov nplaum WD8166A / B muaj daim ntawv thov dav thiab tsim cov rooj plaub.
Qhov nyuaj ntawm cov kuab tshuaj tsis muaj laminating, luam PET / Al yog tam sim no daws los ntawm peb WD8262A / B.Peb tau koom tes nrog ntau tus neeg muab khoom siv, sim thiab kho nws ntau txhiab zaus, thiab thaum kawg ua WD8262A / B nrog kev ua haujlwm zoo.Hauv xeev Hunan, peb cov neeg siv khoom muaj kev txaus siab rau Aluminium retorting laminates, thiab nws yooj yim dua rau lawv los ua qhov kev sim.Rau luam PET / AL / RCPP substrate, txhua txheej yog coated nrog WD8262A / B.Rau luam PET / PA / AL / RCPP, PET / PA thiab AL / RCPP txheej yog siv WD8262A / B.Qhov hnyav ntawm txheej yog nyob ib ncig ntawm 1.8 - 2.5 g / m2, thiab ceev yog nyob ib ncig ntawm 100m / min - 120m / min.
Kangda cov khoom tsis muaj kuab tshuaj tam sim no tau ua tiav zoo hauv qab 128 ℃ thiab ua kom nyuaj rau 135 ℃ txawm tias 145 ℃ siab kub retorting kho.Tshuaj tiv thaiv kuj tseem nyob hauv kev tshawb fawb.
PERFORMANCE TEST
| Qauv | SUBSTRATES | PEELING zog tom qab 121℃ RETORTING |
| WD8166A/B | PA/RCPP | 4-5 N |
| WD8262A/B | AL/RCPP | 5-6 Nr |

Kev nyuaj:
Qhov teeb meem tseem ceeb los tsim cov plaub-txheej aluminium retorting pouches yog nrhiav kev sib xyaw ua ke ntawm cov khoom sib txawv, suav nrog cov yeeb yaj kiab, nplaum, number case thiab hnyav.Tshwj xeeb tshaj yog, kev tsim cov ntawv luam tawm PET / AL no yog qhov nyuaj tshaj plaws.Peb tau ntsib cov teeb meem no uas, thaum peb nqa cov ntaub ntawv los ntawm cov neeg siv khoom mus rau peb lub chaw kuaj mob thiab kuaj tag nrho cov khoom suav nrog cov khoom siv, tsis pom muaj qhov tsis raug.Txawm li cas los xij, thaum peb muab tag nrho cov ntsiab lus, kev ua haujlwm ntawm laminates tsis txaus siab.Tsuas yog thaum tag nrho cov thev naus laus zis, khoom siv, cov khoom siv tau tswj hwm tag nrho, lub substrate tuaj yeem ua tiav.Lwm lub Hoobkas tuaj yeem ua qhov substrate no tsis txhais tau tias leej twg tuaj yeem ua tiav ib yam nkaus.
2. Tswj cov ntsiab lus thaum lub sij hawm tsim khoom
1) Txheej hnyav yog nyob ib ncig ntawm 1.8 - 2.5 g / m2.
2) Cov av noo nyob ib puag ncig
Cov av noo hauv chav yog pom zoo kom tswj ntawm 40% - 70%.Cov dej uas muaj nyob hauv huab cua yuav koom nrog cov tshuaj tiv thaiv ntawm cov nplaum, cov av noo siab yuav txo qhov hnyav molecular ntawm cov nplaum thiab nqa qee qhov kev cuam tshuam, cuam tshuam kev ua haujlwm ntawm retorting kuj.
3) Kev teeb tsa ntawm laminator
Raws li cov cav tov sib txawv, cov chaw tsim nyog xws li nro, siab, tov khoom yuav tsum tau kuaj kom pom ib daim ntawv thov kom raug thiab ua laminates tiaj tus.
4) Cov kev xav tau rau cov yeeb yaj kiab
Zoo planeness, tsim nyog tus nqi dyne, shrinkage thiab noo noo cov ntsiab lus thiab lwm yam yog tag nrho cov tsim nyog tej yam kev mob rau retorting laminating.
3. Cov kev xav yav tom ntej
Tam sim no, daim ntawv thov ntawm cov kuab tshuaj-dawb lamination yog nyob rau ntawm lub ntim hloov tau yooj yim, uas muaj kev sib tw hnyav.Ntawm tus kheej cov ntsiab lus, muaj 3 txoj hauv kev rau cov kuab tshuaj tsis muaj lamination los tsim.
Ua ntej, ib qho qauv nrog ntau daim ntawv thov.Ib qho khoom lag luam tuaj yeem tsim cov substrates feem ntau ntawm cov chaw tsim khoom lag luam hloov pauv, uas tuaj yeem txuag tau ntau lub sijhawm, nplaum thiab ua kom muaj txiaj ntsig zoo.
Thib ob, kev ua haujlwm siab dua, uas muaj kev ua haujlwm siab ntawm cov cua sov thiab tshuaj.
Thaum kawg, kev nyab xeeb ntawm zaub mov.Tam sim no hnyav-dawb lamination muaj kev pheej hmoo ntau dua li hnyav-puag lamination vim nws muaj qee qhov kev txwv ntawm cov khoom lag luam siab xws li 135 ℃ retorting pouches.
Qhov tseem ceeb tshaj, hnyav-dawb laminating yog tsim sai, ntau thiab ntau dua tshiab technologies tau tawm los.Nyob rau hauv lub neej yav tom ntej, hnyav-dawb laminating tej zaum yuav siv ib tug loj account ntawm kev ua lag luam rau saj zawg zog ntim thiab lwm yam teb.
