Konke Odinga Ukukwazi Mayelana Nezinto Ezinamathelayo Ezizwela Ingcindezi Kumafilimu Avikelayo

I-adhesive ezwela ukucindezela isetshenziswe ngaphakathiAmafilimu Okuvikela ingahlukaniswa ngezigaba ezine: irabha yemvelo, irabha yokwenziwa, i-acrylic encibilika emanzini, ne-acrylic esekelwe ku-solvent. Isihluthulelo sokuhle nokubi sefilimu yokuzivikela sinqunywa izici zokunamathela, ezinezici ezihlukene.

1. Irabha yemvelo inokubumbana okuphezulu, ngakho-ke ngokuvamile ayikhiqizi iglue esele. I-resin kanye nezithasiselo zilawula i-viscosity. Nokho, inqubo yokumboza iyinkimbinkimbi kakhulu; kuyadingeka ukusebenzisa i-primer kufilimu kuqala ukuthuthukisa amandla angaphezulu kwefilimu ngaphambi kokuba irabha yemvelo ifakwe kwifilimu ye-PE.Ezindaweni ezingaphakathi endlini, irabha yemvelo ingahlala ingashintshile kuze kube yiminyaka emibili, kodwa incipha futhi iba budala phakathi nezinyanga ezi-3-12 lapho ivezwa ukukhanya kwe-UV. Ifilimu elivikelayo elimnyama nelimhlophe elimelana ne-UV ngokuvamile lakhiwa izingqimba ezintathu: ungqimba olungaphakathi, olumnyama, lungakwazi ukumunca ngokuphumelelayo imisebe ye-ultraviolet; ungqimba oluphakathi, olumhlophe, lungabonisa ukukhanya ukuze ifilimu evikelayo ingakwazi ukumunca amandla amancane, inciphise ukuguga kwejeli, ungqimba olungaphezulu: olumhlophe: lungamboza ngokuphelele umnyama wengqimba yangaphakathi, umbala omhlophe omsulwa ungaphrintwa. amahle kakhulu. Ngakho ngisho nangemva kwezinyanga eziyi-12 zokuchayeka ngaphandle, irabha ngeke iguge. Susa izinkathazo zabakhiqizi. Irabha yemvelo evamile inombala ophuzi okhanyayo. Ukunamathela kokuqala kwenjoloba yemvelo kuhle, futhi kuyinselele ukuqaqa ingcina nengcina ngokuthintana.

2. Irabha yokwenziwa inganikeza i-viscosity ephakeme kanye nokumelana nesimo sezulu

Irabha yokwenziwa inganikeza i-viscosity ephakeme kanye nokumelana nesimo sezulu, kodwa isikhathi eside, ingcina izophulukiswa, futhi i-viscosity yokuqala iyancishiswa, ngakho-ke irabha yokwenziwa ngokuvamile yengezwa kunjoloba yemvelo.

3. I-acrylic encibilikayo emanzini ingamanzi njengendlela yokuncibilikisa i-acrylic monomer

Njengoba enobungani bemvelo futhi engazidingi izinto zokubuyisela i-solvent, amazwe asathuthuka ngokuvamile asebenzisa ama-colloid ancibilika emanzini ukuze akhiqize ifilimu evikelayo. I-acrylic encibilikayo emanzini inezici zefilimu yokuzivikela esekelwe ku-solvent. I-adhesive surface yefilimu evikelayo encibilikayo emanzini kufanele igweme futhi inciphise ukuthintana nomhwamuko wamanzi ukuvimbela ukunamathela okusele. Ifilimu yokuvikela enamathelayo encibilikayo emanzini ibonakala ngokudabula okulula kakhulu nokushesha. Ifilimu yokuvikela ye-acrylic encibilikayo emanzini e-United States nase-Asia enokuningi.

4. I-acrylic esekwe ku-solvent iwukusebenzisa izincibilikisi zemvelo njengendlela yokuncibilikisa i-acrylic monoma

Ukunamathela kwe-Acrylic kusobala futhi amelana nokuguga kuze kube yiminyaka eyi-10. I-adhesive iphinde yelaphe kancane uma ichayeke ekukhanyeni kwe-UV. Uma kuqhathaniswa nerabha, izinamathiselo ze-acrylic zine-tack ephansi yokuqala. Ngemuva kokuthi ifilimu ihlanjululwe nge-corona, i-adhesive ye-acrylic ingasetshenziswa ngokuqondile ngaphandle kwe-primer. Amafilimu e-Acrylic enza i-jittery, umsindo ohlabayo lapho eqaqa, kuyilapho amafilimu enjoloba ekhululeka ngomsindo othambile kakhulu. Uma iqhathaniswa ne-adhesive ye-acrylic, irabha ibushelelezi kakhulu futhi inoketshezi oluhle. Ngemuva kokucindezelwa, ngokushesha yenza ukuthintana okuphelele nendawo okuzosetshenziswa, ngakho-ke inzuzo ebaluleke kakhulu yefilimu yokuvikela yohlobo lwenjoloba ukuthi ingcina isetshenziswa ngokushesha, futhi ukunamathela kokugcina kufinyelelwa ngokushesha ngemuva kokucindezelwa yi-roller. . Ifanele ukusika ngemboni yebhodi futhi ilungele kakhulu umsebenzisi wokugcina ukudabula ifilimu. Ezindaweni ezimahhadlahhadla, ngemuva kwengcindezi, izinzuzo ze-fluidity enhle yama-molecule enjoloba zisobala kakhulu; bangacindezelwa ngokushesha ekucindezelekeni okuhlukahlukene futhi babe nokuxhumana okugcwele ebusweni.

Irabha ye-acrylic inzima futhi ihamba kahle, ngakho ukunamathela kwefilimu yokuzivikela ye-acrylic kudlala kancane kancane; ngisho nangemva kokucindezelwa, ijeli nobuso obuzothunyelwa akukwazi ukuthintwa ngokugcwele. Kubekwe izinsuku ezingu-30-60 kamuva, kuyoba ukuxhumana okugcwele nobuso obuzothunyelwa ukuze kuzuzwe ukunamathela kokugcina, futhi ukunamathela kokugcina kuvame ukuba kukhulu kunokunamathela kokunamathela kwe-viscosity izikhathi ezingu-2-3.
