Ukuthuthukiswa kokupakishwa okuhlanganisiwe okuguquguqukayo kuze kube namuhla, ukunciphisa nokususa izincibilikisi ze-organic enhlanganisela sekuphenduke isiqondiso semizamo ehlanganyelwe yemboni yonke. Njengamanje, izindlela ezihlanganisiwe ezingaqeda ngokuphelele izincibilikisi ziyinhlanganisela yamanzi ne-solvent-free composite. Ngenxa yethonya lobuchwepheshe bezindleko nezinye izici, inhlanganisela engancibilikiyo isesigabeni se-embryonic. I-adhesive-based based adhesive ingasetshenziswa ngokuqondile emshinini ohlanganisiwe owomile okhona, ngakho-ke wamukelwa abakhiqizi basekhaya abaguquguqukayo, futhi uzuze ukuthuthukiswa okusheshayo emazweni angaphandle.
Ingxube yamanzi ihlukaniswe yaba yinhlanganisela eyomile futhi emanzi, inhlanganisela emanzi isetshenziswa ikakhulukazi epulasitiki yephepha, i-aluminium yephepha ehlanganisiwe, i-latex emhlophe iyathandwa kulo mkhakha. Ku-plastic-plastic composite kanye ne-plastic-aluminium composite, i-polyurethane yamanzi kanye ne-acrylic polymer esekelwe emanzini isetshenziswa kakhulu. Izinamathiselo ezisekelwe emanzini zinezinzuzo ezilandelayo:
(1) Amandla ahlanganisiwe aphezulu. Isisindo samangqamuzana sokunamathisela okusekelwe emanzini sikhulu, okuyizikhathi eziningi kune-polyurethane adhesive, futhi amandla ayo okubopha asekelwe ikakhulukazi ku-van der Waals force, okuyingxenye ye-adsorption ebonakalayo, ngakho inani elincane kakhulu leglue lingakwazi ukuzuza. amandla ahlanganisiwe aphezulu. Isibonelo, uma kuqhathaniswa ne-adhesive yezingxenye ezimbili ze-polyurethane, kwinqubo eyinhlanganisela yefilimu e-aluminium, ukumbozwa kwe-glue eyomile okungu-1.8g/m2 kungafinyelela amandla ahlanganisiwe we-2.6g/m2 yeglue eyomile ye-adhesive yezingxenye ezimbili ze-polyurethane.
(2) Ithambile, ifaneleka kakhulu ukuhlanganiswa kwefilimu ye-aluminium yokucwenga. Izinamatheliso ezisekelwe emanzini ezinengxenye eyodwa zithambile kunezingxenye ezimbili ze-polyurethane adhesives, futhi uma zisethwa ngokugcwele, izinamathiselo ze-polyurethane ziqinile kakhulu, kuyilapho izinamathiselo ezisekelwe emanzini zithambile kakhulu. Ngakho-ke, izakhiwo ezithambile kanye nokunwebeka kwe-adhesive yamanzi zifaneleka kakhulu kwifilimu ehlanganisiwe ye-aluminium plating, futhi akulula ukuholela ekudlulisweni kwefilimu ye-aluminium plating.
(3) Awudingi ukuvuthwa, ngemva kokuba umshini ungasikwa. Inhlanganisela ye-adhesive yamanzi-ingxenye eyodwa ayidingi ukuguga, futhi ingasetshenziselwa izinqubo ezilandelayo ezifana ne-slitter kanye nezikhwama ngemuva kokwehla. Lokhu kungenxa yokuthi amandla okuqala okunamathela okunamathiselwe okusekelwe emanzini, ikakhulukazi amandla aphezulu okugunda, aqinisekisa ukuthi umkhiqizo ngeke ukhiqize "umhubhe", ukugoqa kanye nezinye izinkinga ngesikhathi sokuhlanganisa nokusika. Ngaphezu kwalokho, amandla efilimu ahlanganiswe nama-adhesives asekelwe emanzini angakhuphuka ngo-50% ngemva kwamahora angu-4 okubekwa. Lapha akuwona umqondo wokuvuthwa, i-colloid ngokwayo ayenzeki i-crosslinking, ikakhulukazi ngokulingana kweglue, amandla ahlanganisiwe nawo ayanda.
(4) Ungqimba olunamathelayo oluncane, ukukhanya okuhle. Ngenxa yokuthi inani lokunamathisela le-gluing le-gluing elisekelwe emanzini lincane, futhi ukugxila kwe-gluing kuphakeme kunama-adhesive asekelwe ku-solvent, amanzi okudingeka omiswe futhi akhishwe angaphansi kakhulu kunama-adhesive asekelwe ku-solvent. Ngemuva kokuthi umswakama usomile ngokuphelele, ifilimu izoba sobala kakhulu, ngoba ungqimba lwe-adhesive luncane, ngakho-ke ukucaca kwenhlanganisela nakho kungcono kune-adhesive-based adhesive.
(5) Ukuvikelwa kwemvelo, okungenangozi kubantu. Azikho izinsalela ze-solvent ngemva kokomiswa kwezinamatheliso ezisekelwe emanzini, futhi abakhiqizi abaningi basebenzisa izinamathiselo ezisekelwe emanzini ukuze bagweme izincibilikisi ezisele ezilethwa yinhlanganisela, ngakho-ke ukusetshenziswa kwezinamathiselo ezisekelwe emanzini kuphephile ukukhiqiza futhi akulimazi impilo opharetha.
