Munyaya yekuisa laminating isina solvent, kuisa laminating pakupisa kwakanyanya kwave kuri dambudziko rakaoma mumakore mashoma apfuura. Pamwe chete nekugadzirwa kwemidziyo, manamatiro uye matekinoroji, kuisa laminating isina solvent yepurasitiki ine purasitiki iri pasi pe121℃ kwave kushandiswa zvakanyanya pakati pevagadziri vemapakeji anochinjika. Uyezve, huwandu hwemafekitori anoshandisa PET/AL, AL/PA nePlastic/AL pakuisa laminating pa121℃ huri kuwedzera.
Pepa iri richatarisa pakuvandudzwa kwazvino, nzvimbo dzekudzora panguva yekugadzira uye mafambiro emangwana.
1. Kuvandudzwa kwazvino
Mapoketi ekudzoreredza torti iye zvino akakamurwa kuita mhando mbiri dzesubstrates, purasitiki/purasitiki uye purasitiki/aruminiyamu. Zvichienderana nezvinodiwa neGB/T10004-2008, maitiro ekudzoreredza torti akarongwa sehafu-yepamusoro tembiricha (100℃ - 121℃) uye tembiricha yepamusoro (121℃ - 145℃) zviyero zviviri. Parizvino, laminating isina solvent yakafukidza 121℃ uye pasi pe121℃ kurapwa kwekuvhiyiwa.
Kunze kwezvinhu zvinozivikanwa PET, AL, PA, RCPP, zvinoshandiswa pakugadzira laminates nhatu kana ina, zvimwe zvinhu zvakaita semafirimu akajeka ealuminium, PVC inodzoreredza zvinoonekwa pamusika. Kunyange zvazvo pasina kugadzirwa kukuru uye kushandiswa, zvinhu izvozvo zvinoda nguva yakawanda uye kuyedzwa kwakawanda kuti zvishandiswe zvakanyanya.
Parizvino, chinonamira chedu cheWD8262A/B chine mabhokisi anobudirira akaiswa pachikamu chePET/AL/PA/RCPP, chinogona kusvika 121℃ chinodzoreredza. Kune chikamu chepurasitiki/purasitiki chePA/RCPP, chinonamira chedu cheWD8166A/B chinoshandiswa zvakanyanya uye mabhokisi akagadzirwa.
Dambudziko guru rekuisa laminating isina solvent, PET/Al yakadhindwa ragadziriswa neWD8262A/B yedu. Takabatana nevatengesi vemidziyo vakati wandei, tikaiedza uye tikaigadzirisa kanopfuura ka1,000, uye pakupedzisira takagadzira WD8262A/B nekushanda kwakanaka. Mudunhu reHunan, vatengi vedu vanofarira zvikuru maAluminium retorting laminates, uye zviri nyore kuti vaedze. Kune substrate yakadhindwa yePET/AL/RCPP, ma layer ese akafukidzwa neWD8262A/B. Kune PET/PA/AL/RCPP yakadhindwa, ma layer ePET/PA neAL/RCPP anoshandiswa WD8262A/B. Kurema kwe coating kuri pakati pe1.8 - 2.5 g/m2, uye kumhanya kuri pakati pe100m/min - 120m/min.
Zvigadzirwa zvisina solvent zveKangda zvafambira mberi zvikuru pasi pe128℃ uye zvinoramba zvichinetsa kurapwa kwe135℃ kunyangwe 145℃. Kusashanda kwemakemikari kuri kutsvagurudzwawo.
KUYEDZA KWEMAITIRO
| MUENZANISO | ZVINHU ZVINOSANGANISWA | SIMBA REKUBVISA PASHURE PE121℃ KUDZOKORORA |
| WD8166A/B | PA/RCPP | 4-5N |
| WD8262A/B | AL/RCPP | 5-6N |
| WD8268A/B | AL/RCPP | 5-6N |

Matambudziko:
Dambudziko guru rekugadzira mapoketi ekurumisa aruminiyamu ane mativi mana nderekutsvaga musanganiswa wakakodzera wezvinhu zvakasiyana-siyana, zvinosanganisira mafirimu, zvinonamira, inki uye zvinonyungudutsa. Kunyanya, kugadzira PET/AL yakadhindwa zvizere iyi layer yekunze ndiyo yakanyanya kuoma. Taimbosangana nemamiriro ezvinhu aya ekuti, patakatora zvinhu kubva kuvatengi kuenda kurabhoritari yedu toedza zvinhu zvese kusanganisira michina, hapana chakaipa chakawanikwa. Zvisinei, patakabatanidza zvinhu zvese, mashandiro elaminates aisagutsa. Kana matekinoroji ese, michina, zvinhu zvave pasi pekutonga kwakazara, substrate inogona kugadzirwa zvinobudirira. Dzimwe fekitori dzinogona kugadzira substrate iyi hazvirevi kuti pane anogona kubudirirawo.
2. Nzvimbo dzekudzora panguva yekugadzira
1) Kurema kwekuputira kunenge 1.8 - 2.5 g/m2.
2) Hunyoro hwakakomberedza
Hunyoro hwemukamuri hunokurudzirwa kudzora pakati pe40% - 70%. Mvura iri mumhepo ichabatanidzwa mukupindirana kweglue, hunyoro hwakawanda hunoderedza huremu hweglue uye hunounza zvimwe zviitiko, zvichikanganisa mashandiro ekudzivirira kudzoreredza.
3) Zvirongwa pa laminator
Zvichienderana nemichina yakasiyana, marongero akakodzera akadai sekumanikidzwa, kumanikidzwa, uye kusanganisa anofanirwa kuyedzwa kuti awane kushanda kwakakodzera uye kuita kuti laminate isatsvedze.
4) Zvinodiwa pamafirimu
Kugadzikana kwakanaka, kukosha kwakakodzera kwedhine, kuderera uye hunyoro nezvimwewo zvese zvinodiwa pakugadzirisa laminating.
3. Mafambiro emangwana
Parizvino, kushandiswa kwelamination isina solvent kuri pakurongedza kunochinjika, uko kune makwikwi makuru. Panyaya dzemunhu, kune nzira nhatu dzekugadzira lamination isina solvent.
Chekutanga, modhi imwe ine mashandisirwo akawanda. Chigadzirwa chimwe chete chinogona kugadzira substrates dzakawanda dzemugadziri wemapakeji anochinjika, izvo zvinogona kuchengetedza nguva yakawanda, kunamira uye kuwedzera kushanda zvakanaka.
Chechipiri, kushanda kwepamusoro, izvo zvinopa kuramba kwakanyanya kwekupisa nemakemikari.
Chekupedzisira, kuchengetedzeka kwechikafu. Iye zvino lamination isina solvent ine njodzi dzakawanda kupfuura lamination ine solvent-base sezvo ine zvimwe zvinorambidzwa pazvigadzirwa zvinoshanda zvakanyanya zvakaita semapochi anodzoreredza 135℃.
Pamusoro pezvose, laminating isina solvent iri kukura nekukurumidza, matekinoroji matsva akawanda abuda. Mune ramangwana, laminating isina solvent inogona kutora nzvimbo yakakura yemusika wekurongedza kunochinjika uye mamwe mabasa.
