Ubushushu obuphantsi befilimu yangaphambi kokugqumainokuba lilizwi lokuqala olivileyo.Unokuba namathandabuzo kwangoko, ngaba yimveliso entsha?Ngaba ifilimu yokugquma iqondo eliphantsi lobushushu obuphantsi iyafana nefilimu ebandayo yelamination?Yintoni umahluko phakathiifilimu enamathelayo enobushushu obuphantsikunye nefilimu encamathelayo enobushushu obuphezulu?
Vumela u-EKO aphendule imibuzo yakho nganye nganye.
Ubushushu obuphantsi befilimu yangaphambi kokugquma ayisiyiyo ifilimu yokuthambisa ebandayo, kwaye iye yatsala umdla omkhulu kwibala lesicelo sefilimu ethambisayo ebandayo ukususela ekuqalisweni kwayo.Ezinye izinto kwifilimu ebandayo ye-lamination zithandwa kwi-oxidation ekuhambeni kwexesha, okukhokelela ekubeni ube tyheli kumzimba wefilimu.Ngokukodwa xa ubonakaliswe ekukhanyeni kwelanga okanye ukusetyenziswa kwexesha elide, ingxaki ye-oxidation okanye i-yellowing ibaluleke kakhulu.Ifilimu epholileyo yokuthambisa inokubangela iingxaki zokuncamathela okungafezekanga, njengamaqamza omoya.Nangona kunjalo, iifilimu eziphantsi kweqondo lokushisa elisezantsi zinenzuzo enkulu ngokubhekiselele kumgangatho kunye nexabiso.
Inzuzo enkulu yeefilimu ezidibeneyo eziphantsi kweqondo lokushisa liphantsi kweqondo lokushisa kunye neempawu eziphantsi.Xa kuthelekiswa neefilimu zemveli ezigqunywe ngaphambili ezifuna amaqondo obushushu aphezulu edityanisiweyo, iqondo lobushushu elihlanganisiweyo leefilimu ezinobushushu obuphantsi bumalunga nama-85 ℃~90 ℃, ngelixa iifilimu eziqhelekileyo ezigqunywe ngaphambili zifuna ubushushu obuhlanganisiweyo be-100 ℃ ~ 120 ℃.Ubushushu obuphantsi obudibeneyo bunokuthintela ukuguqulwa kunye nokunyibilika kwezinto.Xa kuthelekiswa neefilimu eziqhelekileyo zokugquma kwangaphambili, iifilimu ezinobushushu obuphantsi zilungele izinto ezibuthathaka zobushushu.Umzekelo, izixhobo zokushicilela ze-PP, izixhobo ze-PVC, iphepha le-thermosensitive, njl., kunye ne-curling kunye ne-edge warping issues xa usebenzisa iifilimu eziqhelekileyo zokugquma iilebhile zokuncamathelisa, ukusetyenziswa kwefilimu ezisezantsi zobushushu zangaphambili zithintela ukonakala kwezinto okanye ukuthotywa komgangatho. obangelwa ngamaqondo obushushu aphezulu.
Okwesibini, ifilimu ephantsi kweqondo lokushisa elisezantsi lisebenza kakuhle kakhulu.Ngenxa yokuba ifilimu ephantsi yobushushu be-pre-coating ayilonakalisi isakhiwo sezinto eziphathekayo ngexesha lenkqubo yokunyibilika kwe-adhesive layer, inokufezekisa umphumo okhuselekileyo wokudibanisa.Ngaphezu koko, inkqubo yokudibanisa ifilimu ephantsi kweqondo lokushisa eliphantsi likhawuleza, ngaphandle kwesidingo sokulinda ixesha elide, eliphucula ukusebenza kakuhle.
Ukongezelela, ifilimu ephantsi kweqondo lokushisa elisezantsi libuye libe nokusebenza kokusingqongileyo.Xa kuthelekiswa nokwaleka ngoko nangoko ngokwesiko,ubushushu obuphantsi precoatingayikhuphi iigesi eziyingozi ngexesha lokusetyenziswa.Ngelizwi, ifilimu ye-adhesive ye-Hot-melt ephantsi yobushushu obuphantsi, kunye neenzuzo zayo zokushisa okuphantsi kwe-composite, ukusebenza kweendleko eziphezulu, ukulungelelaniswa kakuhle kunye nokukhuselwa kwendalo, ibe yinto entsha kubathengi abaninzi abaneemfuno ezidibeneyo.Kumashishini ahlukeneyo, iifilimu ezinamathele ezinobushushu obuphantsi ziqhuba ukuphuculwa kwenkqubo kunye nokuphucula ukusebenza kakuhle.Khetha ifilimu yobushushu obuphantsi ukuqinisekisa umgangatho weemveliso zakho.
