Akwụkwọ a ga-elekwasị anya na mmepe kachasị ọhụrụ, isi ihe nchịkwa n'oge mmepụta na usoro n'ọdịnihu.
1. Kacha ọhụrụ mmepe
A na-ekewa obere akpa ndị na-eweghachite ugbu a ụzọ abụọ nke mkpụrụ osisi, plastik / plastic na plastic / aluminom.Dị ka GB / T10004-2008 chọrọ, retorting usoro na nkewa dị ka ọkara-elu okpomọkụ (100 ℃ - 121 ℃) na elu okpomọkụ (121 ℃ - 145 ℃) abụọ ụkpụrụ.Ugbu a, ihe mgbaze-free laminating ekpuchiwo 121 ℃ na n'okpuru 121 sterilization ọgwụgwọ.
Ewezuga ihe ndị a maara nke ọma PET, AL, PA, RCPP, nke a na-eji maka laminates atọ ma ọ bụ anọ, ụfọdụ ihe ndị ọzọ dị ka ihe nkiri alumini nke transperent, na-emegharị PVC na-apụta n'ahịa.Ọ bụ ezie na enweghị nnukwu nrụpụta na ngwa, ihe ndị ahụ chọrọ oge karịa na nnwale ọzọ maka iji nnukwu ya eme ihe.
Ugbu a, nrapado anyị WD8262A/B nwere ihe ịga nke ọma ikpe etinyere na mkpụrụ PET/AL/PA/RCPP, nke nwere ike iru 121 ℃ retorting.Maka mkpụrụ rọba / rọba PA/RCPP, nrapado anyị WD8166A/B nwere ngwa sara mbara yana ikpe mepere emepe.
Isi ihe siri ike nke laminating na-enweghị ihe mgbaze, PET / Al ebipụtara ugbu a site na WD8262A/B anyị.Anyị na-akwado ọtụtụ ndị na-ebu ngwá ọrụ, nwalere ma mezie ya ugboro puku, wee mee WD8262A/B na arụmọrụ dị mma.Na mpaghara Hunan, ndị ahịa anyị nwere oke ịnụ ọkụ n'obi na Aluminom retorting laminates, ọ dịkwa mma maka ha ịme ikpe ahụ.Maka mkpụrụ akwụkwọ PET/AL/RCPP ebipụtara, ejiri WD8262A/B kpuchie akwa niile.Maka ebipụta PET/PA/AL/RCPP, PET/PA na AL/RCPP n'ígwé na-eji WD8262A/B.Ibu mkpuchi dị gburugburu 1.8 - 2.5 g / m2, na ọsọ bụ gburugburu 100m / min - 120m / min.
Kangda ihe mgbaze na-enweghị ngwaahịa ugbu a enwetawo ọganihu dị ukwuu n'okpuru 128 ℃ ma nọgide na-esiri ike maka 135 ℃ ọbụna 145 ℃ ọgwụgwọ na-emegharị okpomọkụ.A na-enyochakwa nguzogide kemịkalụ.

Ihe isi ike:
Isi nsogbu iji rụpụta obere akpa mkpuchi aluminom anọ bụ ịchọta ngwakọta kwesịrị ekwesị nke ihe dị iche iche, gụnyere ihe nkiri, adhesives, ink na ihe mgbaze.Karịsịa, imepụta PET/AL zuru oke nke oyi akwa a dị n'èzí bụ nke kacha sie ike.Anyị na-eche ikpe ndị a ihu na, mgbe anyị na-ebuga ihe ndị ahịa na-aga n'ụlọ nyocha anyị ma nwalee ihe niile gụnyere akụrụngwa, ọ nweghị ntụpọ ọ bụla.Otú ọ dị, mgbe anyị jikọtara ihe niile, arụmọrụ nke laminates adịghị mma.Naanị mgbe teknụzụ niile, akụrụngwa, akụrụngwa na-achịkwa nke ọma, enwere ike ịme mkpụrụ ahụ nke ọma.Ụlọ ọrụ ndị ọzọ nwere ike ime ka mkpụrụ a pụtaghị na onye ọ bụla nwere ike nweta ihe ịga nke ọma.
2. Ihe njikwa n'oge nrụpụta
1) Ibu mkpuchi dị gburugburu 1.8 - 2.5 g / m2.
2) Iru mmiri gbara gburugburu
A na-atụ aro iru mmiri ime ụlọ iji chịkwaa n'etiti 40% - 70%.Mmiri dị n'ime ikuku ga-esonye na mmeghachi omume nke nrapado, oke iru mmiri ga-ebelata ịdị arọ molekụla nke nrapado ma weta ụfọdụ mmeghachi omume sub-reactions, na-emetụta arụmọrụ nke nkwụghachi azụ.
3) Ntọala na laminator
Dị ka igwe dị iche iche, ntọala kwesịrị ekwesị dị ka esemokwu, nrụgide, mixer ga-anwale iji chọta ngwa kwesịrị ekwesị ma mee ka laminates dị larịị.
4) Ihe achọrọ maka ihe nkiri
Ezi planeness, ezigbo dyne uru, shrinkage na mmiri ọdịnaya wdg bụ ihe niile dị mkpa ọnọdụ maka retorting laminating.
3. Omume n'ọdịnihu

Nke abuo, arụmọrụ dị elu, nke na-enye nnukwu nguzogide okpomọkụ na kemịkal.
N'ikpeazụ, nchekwa nri.Ugbu a lamination na-enweghị ihe mgbaze nwere ihe ize ndụ karịa lamination-base lamination dị ka o nwere ụfọdụ mgbochi na elu arụmọrụ ngwaahịa dị ka 135 ℃ retorting obere akpa.
Karịsịa, laminating na-enweghị ihe mgbaze na-etolite ngwa ngwa, ọtụtụ teknụzụ ọhụrụ apụtala.N'ọdịnihu, laminating na-enweghị ihe mgbaze nwere ike iburu nnukwu akaụntụ ahịa maka nkwakọ ngwaahịa na-agbanwe agbanwe na ubi ndị ọzọ.
