Uphuhliso lokupakishwa okuhlanganisiweyo okuguquguqukayo ukuza kuthi ga namhlanje, ukunciphisa kunye nokususa izinyibilikisi zezinto eziphilayo kwi-composite kuye kwaba ngulwalathiso lwemigudu edibeneyo yoshishino lonke. Okwangoku, iindlela ezidibeneyo ezinokuphelisa ngokupheleleyo i-solvents ziyi-composite yamanzi kunye ne-solvent-free composite. Ngenxa yempembelelo yetekhnoloji yeendleko kunye nezinye izinto, i-solventless composite isekwinqanaba le-embryonic. I-adhesive yamanzi inokusetyenziswa ngokuthe ngqo kumatshini okhoyo odibeneyo owomileyo, ngoko yamkelwa ngabavelisi basekhaya abaguquguqukayo, kwaye iphumelele uphuhliso olukhawulezayo kumazwe angaphandle.
I-composite esekelwe emanzini ihlulwe ibe yimbumba eyomileyo kunye neyomanzi, i-composite emanzi isetyenziswa kakhulu kwiplastiki yephepha, i-aluminium yephepha edibeneyo, i-latex emhlophe ithandwa kule ntsimi. Kwiplastiki-iplastiki yeplastiki kunye ne-aluminium-aluminium composite, i-polyurethane yamanzi kunye ne-acrylic-polymer ye-acrylic isetyenziswa kakhulu. Izinto zokuncamathelisa ezisekelwe emanzini zinezi nzuzo zilandelayo:
(1) Amandla aphezulu adibeneyo. Ubunzima bemolekyuli yokuncamathelisa esekwe emanzini bukhulu, obuphindaphindene kaninzi kunobo beglue encamatheleyo, kwaye amandla ayo okuncamathela asekelwe ubukhulu becala kumandla evan der Waals, aphuma kwi-adsorption ebonakalayo, ngoko ke inani elincinci kakhulu leglu linokufikelela ngokupheleleyo. amandla ahlanganisiweyo aphezulu. Ngokomzekelo, xa kuthelekiswa ne-adhesive-component polyurethane adhesive, kwinkqubo edibeneyo yefilimu ye-aluminium, i-coating ye-1.8g / m2 yeglue eyomileyo inokufezekisa amandla adibeneyo we-2.6g / m2 yeglue eyomileyo ye-adhesive-component polyurethane adhesive.
(2) Ithambile, ifaneleke ngakumbi ifilimu yokucoca i-aluminiyam. I-adhesives esekelwe emanzini enecandelo elinye ithambile kune-adhesives ye-polyurethane, kwaye xa ibekwe ngokupheleleyo, i-polyurethane adhesives iqinile kakhulu, ngelixa i-adhesives esekelwe emanzini ithambile kakhulu. Ngako oko, iipropati ezithambileyo kunye ne-elasticity ye-adhesive-based adhesive ifaneleke ngakumbi kwi-composite ye-aluminium yokucoca ifilimu, kwaye akulula ukukhokelela ekudlulisweni kwefilimu ye-aluminium yokucoca.
(3) Akufuneki ukuba uvuthwe, emva kokuba umatshini unokunqunyulwa. I-composite ye-adhesive-based adhesive-based adhesive ayifuni ukuba ibe mdala, kwaye ingasetyenziselwa iinkqubo ezilandelayo ezifana ne-slitter kunye ne-bagging emva kokuhla. Oku kungenxa yokuba amandla okuqala okubambelela kwi-adhesive-based adhesive, ingakumbi amandla aphezulu okucheba, aqinisekisa ukuba umkhiqizo awuyi kuvelisa "i-tunnel", ukugoqa kunye nezinye iingxaki ngexesha lokudibanisa kunye nokusika. Ngaphezu koko, amandla efilimu ehlanganiswe kunye ne-adhesives yamanzi inokunyuswa ngama-50% emva kweeyure ze-4 zokubekwa. Nantsi ingcamango yokuvuthwa, i-colloid ngokwayo ayenzeki i-crosslinking, ngokuyinhloko kunye nomgangatho weglue, amandla adibeneyo ayanda.
(4) Umaleko oncamathelayo obhityileyo, ukucaca kakuhle. Ngenxa yokuba i-gluing ye-gluing ye-adhesives-based adhesives encinci, kwaye i-gluing i-gluing iphezulu kune-adhesives-based-adhesives, amanzi afuna ukusomiswa kwaye akhutshwe angaphantsi kakhulu kune-adhesives-based adhesives. Emva kokuba umswakama womile ngokupheleleyo, ifilimu iya kuba yinto ecacileyo kakhulu, kuba i-adhesive layer iyancipha, ngoko ke ukucaca kwe-composite kubhetele kunokuba i-adhesive-based adhesive.
(5) Ukhuseleko lwendalo, olungenabungozi ebantwini. Akukho ntsalela ye-solvent emva kokumiswa kwe-adhesives esekelwe emanzini, kwaye abaninzi abavelisi basebenzisa i-adhesives esekelwe emanzini ukuphepha i-solvents eyintsalela ebangelwa yi-composite, ngoko ke ukusetyenziswa kwe-adhesives-based-adhesives kukhuselekile ukuvelisa kwaye ayonakalisi impilo ye-solvents. umsebenzisi.
