Hauv kev ua cov laminating uas tsis muaj kuab tshuaj, kev kho kom rov qab kub siab tau ua teeb meem nyuaj rau ob peb xyoos dhau los. Thaum nrog rau kev tsim cov khoom siv, cov nplaum thiab cov thev naus laus zis, kev kho kom rov qab tsis muaj kuab tshuaj rau yas nrog yas hauv qab 121 ℃ tau txais kev siv ntau ntawm cov chaw tsim khoom ntim khoom yooj ywm. Ntxiv mus, tus lej ntawm cov chaw tsim khoom uas siv PET / AL, AL / PA thiab Yas / AL rau 121 ℃ retorting tab tom loj hlob.
Tsab ntawv no yuav tsom mus rau qhov kev txhim kho tshiab, cov ntsiab lus tswj hwm thaum lub sijhawm tsim khoom thiab cov qauv yav tom ntej.
1. Kev tsim kho tshiab kawg
Cov hnab retorting tam sim no muab faib ua ob hom substrates, yas / yas thiab yas / txhuas. Raws li GB / T10004-2008 qhov yuav tsum tau ua, cov txheej txheem retorting yog cais ua ib nrab kub siab (100 ℃ - 121 ℃) thiab kub siab (121 ℃ - 145 ℃) ob tus qauv. Tam sim no, laminating tsis muaj kuab tshuaj tau them 121 ℃ thiab qis dua 121 ℃ kev kho mob kom tsis muaj menyuam.
Tsuas yog cov ntaub ntawv paub zoo PET, AL, PA, RCPP, uas siv rau peb lossis plaub txheej laminates, qee cov ntaub ntawv xws li cov yeeb yaj kiab aluminized pob tshab, retorting PVC tshwm sim hauv khw. Txawm hais tias tsis muaj kev tsim khoom loj thiab daim ntawv thov, cov ntaub ntawv no xav tau ntau lub sijhawm thiab kev sim ntau dua rau kev siv ntau.
Tam sim no, peb cov nplaum WD8262A / B muaj cov ntaub ntawv ua tiav siv rau ntawm cov khoom siv 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 ntaub ntawv.
Qhov nyuaj ntawm kev laminating tsis muaj kuab tshuaj, luam tawm PET / Al tam sim no daws tau los ntawm peb WD8262A / B. Peb tau koom tes nrog ntau tus neeg muab khoom siv, sim thiab kho nws rau txhiab zaus, thiab thaum kawg ua WD8262A / B nrog kev ua tau 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 cov ntawv luam tawm PET / AL / RCPP substrate, txhua txheej yog coated nrog WD8262A / B. Rau cov ntawv luam tawm PET / PA / AL / RCPP, PET / PA thiab AL / RCPP txheej yog siv WD8262A / B. Qhov hnyav txheej yog nyob ib puag ncig 1.8 - 2.5 g / m22, thiab qhov ceev yog nyob ib ncig ntawm 100m / min - 120m / min.
Cov khoom Kangda uas tsis muaj kuab tshuaj tam sim no tau ua tiav kev vam meej zoo hauv qab 128 ℃ thiab ua kom nyuaj rau 135 ℃ txawm tias 145 ℃ kub siab retorting kev kho mob. Kev tiv thaiv tshuaj kuj tseem nyob hauv kev tshawb fawb.
KEV NTSUAM XYUAS KEV UA HAUJ LWM
| QAUV | COV SUBSTRATES | ZOG NTAWM PEELING TOM QAB 121℃ ROV QAB |
| WD8166A/B | PA/RCPP | 4-5N |
| WD8262A/B | AL/RCPP | 5-6N |
| WD8268A/B | AL/RCPP | 5-6N |

Kev Nyuaj Siab:
Qhov teeb meem tseem ceeb rau kev tsim cov hnab yas plaub txheej yog nrhiav kev sib xyaw ua ke ntawm cov khoom sib txawv, suav nrog cov yeeb yaj kiab, cov nplaum, cov kua mem thiab cov kuab tshuaj. Tshwj xeeb, kev tsim cov PET / AL uas luam tawm tag nrho cov txheej sab nraud no yog qhov nyuaj tshaj plaws. Peb tau ntsib cov xwm txheej no uas, thaum peb coj cov ntaub ntawv los ntawm cov neeg siv khoom mus rau peb lub chaw soj nstuam thiab kuaj txhua yam khoom suav nrog cov khoom siv, tsis pom qhov tsis zoo. Txawm li cas los xij, thaum peb muab tag nrho cov khoom sib xyaw ua ke, kev ua tau zoo ntawm cov laminates tsis txaus siab. Tsuas yog thaum txhua yam thev naus laus zis, khoom siv, cov ntaub ntawv raug tswj hwm tag nrho, cov khoom siv tuaj yeem ua tiav. Lwm lub Hoobkas tuaj yeem ua cov khoom siv no tsis tau txhais hais tias leej twg tuaj yeem ua tiav thiab.
2. Cov ntsiab lus tswj thaum lub sijhawm tsim khoom
1) Qhov hnyav ntawm txheej yog nyob ib ncig ntawm 1.8 - 2.5 g / m22.
2) Cov av noo ib puag ncig
Cov av noo hauv chav tsev raug pom zoo kom tswj tau 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 ntawm cov nplaum thiab coj qee qhov kev tiv thaiv me me, cuam tshuam rau kev ua haujlwm ntawm kev tiv thaiv retorting.
3) Kev teeb tsa ntawm lub tshuab laminator
Raws li cov tshuab sib txawv, qhov chaw tsim nyog xws li kev nruj, siab, sib tov yuav tsum tau sim kom pom qhov kev siv kom raug thiab ua rau cov laminates tiaj tus.
4) Cov kev cai rau cov yeeb yaj kiab
Zoo planeness, dyne nqi tsim nyog, shrinkage thiab noo noo cov ntsiab lus thiab lwm yam yog txhua yam tsim nyog rau retorting laminating.
3. Cov qauv yav tom ntej
Tam sim no, kev siv cov lamination tsis muaj kuab tshuaj yog rau ntawm cov ntim khoom yooj ywm, uas muaj kev sib tw hnyav. Ntawm cov ntsiab lus ntawm tus kheej, muaj 3 txoj hauv kev rau kev lamination tsis muaj kuab tshuaj los tsim.
Ua ntej, ib qho qauv nrog ntau daim ntawv thov. Ib yam khoom tuaj yeem tsim feem ntau cov khoom siv ntawm cov chaw tsim khoom ntim khoom yooj ywm, uas tuaj yeem txuag tau ntau lub sijhawm, nplaum thiab ua kom muaj txiaj ntsig zoo.
Qhov thib ob, kev ua tau zoo dua, uas muaj kev tiv taus cua sov thiab tshuaj lom neeg siab.
Thaum kawg, kev nyab xeeb ntawm cov khoom noj. Tam sim no lamination tsis muaj kuab tshuaj muaj ntau qhov kev pheej hmoo dua li lamination-based solvent vim nws muaj qee qhov kev txwv rau cov khoom ua tau zoo xws li 135 ℃ retorting hnab.
Qhov tseem ceeb tshaj plaws, kev siv cov tshuaj solvent-free lamination tab tom tsim kho sai, ntau thiab ntau cov thev naus laus zis tshiab tau tshwm sim. Yav tom ntej, kev siv cov tshuaj solvent-free lamination yuav suav nrog ntau yam kev lag luam rau kev ntim khoom yooj ywm thiab lwm yam teb.
