Ngaphambi kokuvelisa i-composite engenasombululo, kuyimfuneko ukufunda ngononophelo amaxwebhu enkqubo yokuvelisa kunye neemfuno kunye namanyathelo okhuseleko malunga nomlinganiselo we-adhesive engenasombululo, ubushushu bokusetyenziswa, ukufuma, iimeko zokuphilisa, kunye neeparamitha zenkqubo. Ngaphambi kokuvelisa, kuyimfuneko ukuqinisekisa ukuba iimveliso ze-adhesive ezisetyenzisiweyo azinazo iingxaki. Nje ukuba kufunyenwe naziphi na izinto ezingaqhelekanga ezichaphazela i-viscosity, kufuneka zimiswe ngoko nangoko kwaye zixelelwe abasebenzi bezobuchwephesha benkampani. Ngaphambi kokusebenzisa umatshini we-laminating ongenasombululo, kuyimfuneko ukufudumeza inkqubo yokuxuba, inkqubo ye-gluing, kunye nenkqubo ye-laminating kwangaphambili. Ngaphambi kokuveliswa kwe-composite engenasombululo, kuyimfuneko ukuqinisekisa ukuba umphezulu wee-roller zerabha, ii-roller eziqinileyo, kunye nezinyeIzixhobo ezikwimatshini edibeneyo engenasombululo zicocekile.
Ngaphambi kokuba uqale, kuyimfuneko ukuqinisekisa kwakhona ukuba umgangatho wemveliso edityanisiweyo uyahlangabezana neemfuno zemveliso edityanisiweyo. Uxinzelelo lomphezulu wefilimu ngokubanzi kufuneka lube ngaphezu kwama-dynes angama-40, kwaye uxinzelelo lomphezulu weefilimu zeBOPA kunye nePET kufuneka lube ngaphezu kwama-dynes angama-50. Ngaphambi kokuveliswa ngobuninzi, ukuthembeka kwefilimu kufuneka kuvavanywe ngokusebenzisa iimvavanyo ukuze kuthintelwe iingozi. Jonga nakuphi na ukuwohloka okanye ukungaqheleki kwi-adhesive. Ukuba kukho naziphi na izinto ezingaqhelekanga ezifunyenweyo, yilahle i-adhesive kwaye ucoce umatshini wokuxuba. Emva kokuqinisekisa ukuba akukho zinto zingaqhelekanga kwi-adhesive, sebenzisa indebe elahlwayo ukujonga ukuba umlinganiselo womatshini wokuxuba uchanekile na. Imveliso inokuqhubeka kuphela emva kokuba ukuphambuka komlinganiselo kungaphakathi kwe-1%.
Ngexesha lenkqubo yemveliso, kuyimfuneko ukuqinisekisa umgangatho wemveliso. Emva kokuhlanganiswa okuqhelekileyo kwe-100-150m, umatshini kufuneka umiswe ukuqinisekisa ukuba inkangeleko edibeneyo, ubungakanani bokugquma, uxinzelelo, njl.njl. lwemveliso ziyahlangabezana neemfuno. Ngexesha lenkqubo yemveliso, zonke iiparameter zenkqubo, kubandakanya ubushushu bokusingqongileyo, umswakama, i-substrate edibeneyo, kunye neeparameter zenkqubo yezixhobo, kufuneka zirekhodwe ukuze kube lula ukulandelela kunye nokuchongwa kwemicimbi yomgangatho.
Iiparameter zobugcisa ezifana nendawo yokusetyenziswa kunye nendawo yokugcina i-glue, ubushushu bokusetyenziswa, ixesha lokusebenza, kunye nomlinganiselo we-glue engenasombululo kufuneka ubhekisele kwincwadana yobugcisa yemveliso. Umswakama kwindawo yokusebenzela kufuneka ulawulwe phakathi kwama-40% -70%. Xa umswakama ukwi-≥ 70%, nxibelelana nabasebenzi bezobugcisa benkampani kwaye wonyuse ngokufanelekileyo i-isocyanate component (i-KangDa New Material A component), kwaye uyiqinisekise ngovavanyo oluncinci ngaphambi kokusetyenziswa ngokusesikweni kwebhetshi. Xa umswakama ongqongileyo ukwi-≤ 30%, nxibelelana nabasebenzi bezobugcisa benkampani kwaye wonyuse ngokufanelekileyo i-hydroxyl component (i-B component), kwaye uyiqinisekise ngovavanyo ngaphambi kokusetyenziswa kwebhetshi. Imveliso kufuneka iphathwe ngononophelo ngexesha lokuthuthwa nokulayisha nokukhulula, ukuthintela ukugoba, ukungqubana, kunye noxinzelelo olukhulu, kunye nokuthintela ukuvezwa ngumoya nelanga. Kufuneka igcinwe kwiimeko ezipholileyo, eziphefumlayo, nezomileyo, kwaye igcinwe ivaliwe ixesha lokugcina leenyanga ezi-6. Emva kokuba umsebenzi wokudibanisa ugqityiwe, ubushushu bokunyanga buyi-35 ° C-50 ° C, kwaye ixesha lokunyanga lihlengahlengiswa ngokwee-substrates ezahlukeneyo zokudibanisa. Umswakama wokunyanga ngokubanzi ulawulwa phakathi kwe-40% -70%.
