Ngaphambi kokuvelisa i-solvent-free composite, kuyimfuneko ukufunda ngononophelo amaxwebhu enkqubo yokuvelisa kunye neemfuno kunye nezilumkiso zomlinganiselo we-adhesive-free adhesive, ubushushu bokusetyenziswa, ukufuma, iimeko zokuphilisa, kunye neeparitha zenkqubo.Ngaphambi kokuveliswa, kuyimfuneko ukuqinisekisa ukuba iimveliso zokubambelela ezisetyenzisiweyo azikho kwizinto ezingaqhelekanga.Emva kokuba nayiphi na into engaqhelekanga echaphazela i-viscosity ifunyenwe, kufuneka imiswe ngokukhawuleza kwaye idityaniswe nabasebenzi bezobugcisa benkampani.Ngaphambi kokusebenzisa umatshini wokuhlamba i-solvent-free, kuyimfuneko ukutshisa inkqubo yokuxuba, inkqubo ye-gluing, kunye ne-laminating system kwangaphambili.Ngaphambi kokuveliswa kwe-solvent-free composite, kuyimfuneko ukuqinisekisa ukuba umphezulu we-rubber rollers, iiroli eziqinileyo kunye nezinye.amacandelo ezixhobo kumatshini we-solvent-free composite ucocekile.
Ngaphambi kokuqala, kuyimfuneko ukuqinisekisa kwakhona ukuba umgangatho wemveliso edibeneyo uyahlangabezana neemfuno zemveliso edibeneyo.Uxinzelelo lomphezulu wefilimu kufuneka ngokubanzi lube likhulu kune-40 dynes, kwaye uxinzelelo lomphezulu lwefilimu ye-BOPA kunye ne-PET kufuneka ibe nkulu kune-50 dynes.Ngaphambi kokuveliswa kobuninzi, ukuthembeka kwefilimu kufuneka kuhlolwe ngokusebenzisa iimvavanyo ukuphepha ingozi.Khangela nakuphi na ukuwohloka okanye ukungaqhelekanga kwi-adhesive.Ukuba kukho naziphi na izinto ezingaqhelekanga ezifunyenweyo, lahla i-adhesive kwaye ucoce umatshini wokuxuba.Emva kokuqinisekisa ukuba akukho nto ingaqhelekanga kwi-adhesive, sebenzisa ikomityi elahlayo ukujonga ukuba umlinganiselo womatshini wokuxuba uchanekile.Imveliso inokuqhubeka kuphela emva kokuphambuka komlinganiselo ngaphakathi kwe-1%.
Ngexesha lenkqubo yokuvelisa, kuyimfuneko ukuqinisekisa umgangatho wemveliso.Emva kokudibanisa okuqhelekileyo kwe-100-150m, umatshini kufuneka umiswe ukuze kuqinisekiswe ukuba imbonakalo edibeneyo, isixa sokugquma, ukuxinana, njl njl.Ngexesha lenkqubo yokuvelisa, zonke iiparameters zenkqubo, kubandakanywa ukushisa kokusingqongileyo, umswakama, i-substrate edibeneyo, kunye neeparitha zenkqubo yezixhobo, kufuneka zirekhodwe ukwenzela ukuba kube lula ukulandelwa kunye nokuchongwa kwemiba yomgangatho.
Iiparamitha zobuchwepheshe ezifana nokusetyenziswa kunye nokugcinwa kwendawo yokubambelela, ukushisa kokusetyenziswa, ixesha lokusebenza, kunye nomlinganiselo we-adhesive-free adhesive kufuneka ubhekiselele kwincwadana yobugcisa bemveliso.Ukufuma kwindawo yokusebenzela kufuneka kulawulwe phakathi kwe-40% -70%.Xa ukufuma ≥ 70%, nxibelelana nabasebenzi bezobugcisa benkampani kwaye ukwandise ngokufanelekileyo icandelo le-isocyanate (i-KangDa New Material A component), kwaye uqinisekise ngovavanyo oluncinci ngaphambi kokusetyenziswa kwebhetshi ngokusemthethweni.Xa ukufuma kokusingqongileyo ≤ 30%, nxibelelana nabasebenzi bobugcisa benkampani kwaye ukwandise ngokufanelekileyo icandelo le-hydroxyl (icandelo le-B), kwaye uqinisekise ngovavanyo ngaphambi kokusetyenziswa kwebhetshi.Imveliso kufuneka iphathwe ngononophelo ngexesha lokuthuthwa kunye nokulayishwa kunye nokothula, ukunqanda ukuthepha, ukungqubana, kunye noxinzelelo olunzima, kunye nokuthintela ukuvela komoya kunye nelanga.Kufuneka igcinwe kwindawo epholileyo, engenamoya, neyomileyo, kwaye igcinwe ivaliwe kangangeenyanga ezi-6.Emva kokuba umsebenzi odibeneyo ugqityiwe, iqondo lokushisa lokunyanga liyi-35 ° C-50 ° C, kwaye ixesha lokunyanga lilungelelaniswa ngokwee-substrates ezahlukeneyo ezidibeneyo.Ukufuma okunyangayo kulawulwa ngokubanzi phakathi kwe-40% -70%.
