Ifilimu ye-EVAluhlobo lwe-hot-melt adhesive, eyi-copolymer ye-ethylene vinyl acetate. Yenziwe ngetekhnoloji yesayensi kwaye ixutywa ngesantya esiphezulu, iplastiki, i-extrusion, i-shaping, i-cooling, i-size kunye neenkqubo zokujika. Emva kokucubungula ibe yifilimu, ayinakunamathela kubushushu begumbi kwaye ixutywa ngokunyibilika ngokusebenzisa i-vacuum hot pressing kwizixhobo ze-glass laminating. Ifilimu ye-EVA ecutshungulwayo inokuguquguquka okugqwesileyo, ukumelana nempembelelo, ukukhanya okuphezulu, kunye nokunamathela okunamandla kakhulu; Ngaphezu koko, inokumelana okunamandla kakhulu nokuqhekeka koxinzelelo lokusingqongileyo, ukumelana nokufuma, ukumelana nemozulu, ukuvalwa kobushushu, kunye nezinye iimpawu. Zizo kanye ezi mpawu zikhoyo kwi-EVA ezikhokelele ekukhuthazweni ngokukhawuleza nasekusetyenzisweni kwefilimu ye-EVA kumashishini eglasi kunye neglasi yobugcisa ukususela ngo-2000. Kwinqanaba lokuqala lophuhliso kunye nokusetyenziswa kwefilimu ye-EVA, ngenxa yeefomyula kunye neenkqubo ezahlukeneyo zobugcisa, yayijoliswe kakhulu kumashishini okucubungula iglasi kwiinkalo zezinto zokuhombisa izakhiwo ngokubanzi, ukuqinisa ucingo kunye ne-glue bonding, njl., ithatha indawo yeziphumo ezimbi kunye neengxaki ezibangelwa yi-adhesive bonding yexesha elide. Iindidi ngeendidi zeemveliso ze-EVA kwimarike ziqalile ukubonisa umkhwa wokwahlukahluka: ukusuka kuhlobo olunye oluqhelekileyo olucacileyo ukuya ekwandiseni nasekukhuliseni umbala ocacileyo, umbala ongacacanga, kunye nothotho lwesanti yediski. Oku kubangelwa yi-catalysis yemarike, ehlangabezana ngokutyebileyo neemfuno zamanqanaba amaninzi zeenkampani zokucubungula iglasi kwiimveliso ze-EVA.
Ngokuphathelele ukugcinwa kwefilimu
Ifilimu yeglasi elaminethiweyo ye-EVA idla ngokufuneka igcinwe kwindawo yokugcina izinto evulekileyo, eyomileyo, necocekileyo, ithintela imitha ethe ngqo evela elangeni nakwimithombo yobushushu: ukuthintela imvula, uxinzelelo olunzima, impembelelo yangaphandle, kunye nemikrwelo evela kwizinto eziqinileyo; Ubushushu bendlu yokugcina izinto kufuneka bulawulwe ngaphantsi kwama-35 ℃, kwaye ukufuma akufuneki kudlule kuma-60%; Xa kukho uluhlu olukhulu lwefilimu, kufuneka kubekwe itreyi phantsi kwefilimu ukuze kube lula ukungena komoya, ukusasazwa kobushushu, kunye nokwahlulwa komswakama. Ukuba ifilimu iphantsi koxinzelelo, ubushushu, okanye ukufuma okugqithisileyo, iya kubonisa amazinga ahlukeneyo okuzincamathelisa okanye ukutyheli kunye nokubomvu kumphezulu wefilimu, okuya kuchaphazela ukusetyenziswa okuqhelekileyo.
Ifilimu eseleyo emva kokusetyenziswa kufuneka iphinde ipakishwe ngezinto ezicocekileyo ukuthintela umbane obuthathaka oshukumayo othwalwa yifilimu ngokwayo ukuba ungafunxi uthuli kwaye ungcolise ifilimu, nto leyo echaphazela ukusetyenziswa kwesiqhelo.
Ukutyibilika okuhle, ngokubanzi kunesiphumo esihle sokucubungula malunga ne-110 ℃. Iglasi yokuhombisa eneepateni kunye noyilo ingenziwa kusetyenziswa iindlela ezifana nee-wire clamps kunye nee-roll clamps kumaleko wefilimu. Ke ngoko, isetyenziselwa ikakhulu izahlulo zangaphakathi kunye nokuhombisa.
Ifilimu ephakathi ye-EVA yipolymer ye-thermoplastic ebonakala kakuhle kwaye inokumelana nempembelelo, isetyenziswa kakhulu kwiindawo zokwakha nakwiimoto. Inokumelana nemozulu okuhle kunye nokumelana ne-UV, nto leyo enokuthintela ngempumelelo ukuguga nokunyamalala kweglasi.
NjengeIfilimu ye-EVAUmenzi kunye nomthengisi bazibophelele ekuveliseni izinto ezintsha kunye nomgangatho, iFangding Technology Co., Ltd. ibisoloko izibophelele ekuboneleleni abathengi ngeefilimu ze-EVA ezisebenza kakuhle nezinemisebenzi emininzi. Ukukhetha imveliso yethu kuthetha ukukhetha isisombululo sezinto ezisemgangathweni ophezulu esibonakalayo, esikhuselekileyo, nesihlala ixesha elide.
