Izinamathiseli ze-lamination ezingenayo i-solventI-lamination iyingxenye ebalulekile enqubweni ye-lamination, ehlinzeka ngesibopho esiqinile nesihlala isikhathi eside phakathi kwezingqimba zezinto ezahlukene. I-lamination iyindlela esetshenziswa kabanzi emikhakheni ehlukahlukene njengokupakisha, ukuphrinta kanye nokukhiqiza ukuze kuthuthukiswe amandla, ukubukeka kanye nokusebenza kwemikhiqizo. I-glue esetshenziswa ngesikhathi senqubo ye-lamination idlala indima ebalulekile ekunqumeni ikhwalithi iyonke kanye nokusebenza kwe-laminate.
Ngesikhathi senqubo yokunamathisela, kufakwa inhlaka phakathi kwezingxenye ezimbili noma ngaphezulu ukuze kwakhiwe izinto ezihlanganisiwe ezinezakhiwo ezithuthukisiwe. Izinhlanhla ezinamathisela i-laminating ezingenayo i-solvent, njengoba igama lisho, azinazo noma yiziphi izinhlanhla eziphilayo eziguquguqukayo (ama-VOC) noma izinhlambululi, okwenza kube ukukhetha okuphephile nokuvikela imvelo kokusetshenziswa kwe-lamination. Lolu hlobo lwenhlaka ngokuvamile luyisistimu enezingxenye ezimbili equkethe i-resin kanye ne-hardener ezisabela ekwakheni isibopho esiqinile ngaphandle kwesidingo sezinhlambululi.
Ukukhethwa kwe-laminating adhesive kuncike ezintweni ezahlukahlukene, okuhlanganisa uhlobo lwe-laminate, amandla e-bond adingekayo, kanye nezidingo ezithile zomkhiqizo wokugcina. Ama-laminating angena-solvent avame ukuthandwa ngenxa yamandla awo aphezulu e-bond, ukumelana okuhle kwamakhemikhali, kanye nokufaneleka kwezicelo zokupakisha ukudla. Ngaphezu kwalokho, i-adhesive engena-solvent inikeza izikhathi zokupholisa ngokushesha, okuvumela inqubo yokukhiqiza ephumelelayo kanye nokukhiqiza okwandisiwe.
Enye yezinzuzo ezibalulekile ze- izinti zokunamathisela ezingenalutho oluyi-solventyikhono labo lokudala izibopho ezingenamthungo nezifanayo phakathi kwezingxenye ezahlukene ezifana nefilimu, i-foil kanye nephepha. Lokhu kuphumela kuma-laminate anezakhiwo ezithuthukisiwe zokuvimbela, ukuqina okuthuthukisiwe kanye nokuqedwa kobungcweti nekhwalithi ephezulu. Ngaphezu kwalokho, ama-adhesive angenawo ama-solvent anegalelo ekuzinzeni kwenqubo yokunamathisela ngokunciphisa ukukhishwa komoya kanye nokunciphisa umthelela wemvelo ohlotshaniswa nama-adhesive asekelwe kuma-solvent.
Izinqubo zokubopha zisetshenziswa ezinhlobonhlobo zezicelo, okuhlanganisa ukupakisha okuguquguqukayo, amalebula kanye nobuciko bezithombe. Embonini yokupakisha eguquguqukayo, izinti zokunamathisela ezingenayo i-solvent zibaluleke kakhulu ngenxa yekhono lazo lokubopha izinhlobo ezahlukene zamafilimu futhi zakhe izakhiwo ezinezingqimba eziningi ezihlinzeka ngokuvikelwa emswakama, umoya-mpilo kanye nezinye izinto zangaphandle. Lokhu kubalulekile ekugcineni ubusha kanye nekhwalithi yemikhiqizo epakishiwe, okwenza izinti ezingenayo i-solvent zibe ukukhetha okuthandwayo kokupakisha ukudla kanye nemithi.
Ezweni lamalebula kanye nobuciko bezithombe, izinti zokunamathisela ezingenayo i-solvent zisetshenziselwa ukuthuthukisa ukubukeka nokuqina kwezinto eziphrintiwe. Ngokuzintiza izinti zokuphrinta ezinezinti ezingenayo i-solvent, abakhiqizi bangafinyelela imibala egqamile, ukuqedwa okukhazimulayo, kanye nokumelana nokuklwebheka kanye namakhemikhali. Lokhu kubalulekile ekukhiqizeni amalebula aheha amehlo, izinto zokuphromotha kanye neminye imikhiqizo ephrintiwe edinga inhlanganisela yobuhle nokusebenza.
Sekukonke, inhlaka esetshenziswa ngesikhathi senqubo yokunamathisela idlala indima ebalulekile ekunqumeni ukusebenza, ukubukeka kanye nokusimama kwe-laminate. Inhlaka yokunamathisela engenazinyibilikisi inikeza izinzuzo eziningi, okuhlanganisa amakhono okubopha aqinile, ubungane bemvelo, kanye nokuguquguquka kuyo yonke imboni. Njengoba isidingo sezixazululo ze-laminate ezisezingeni eliphezulu nezisimeme siqhubeka nokukhula, inhlaka engenazinyibilikisi kulindeleke ukuthi ihlale iyisinqumo sokuqala sabakhiqizi abafuna ukwenza ngcono izinqubo zabo zokunamathisela futhi bahlangabezane nezidingo zemakethe ezishintshayo.
