Epoxy UV ikiza resin ikoreshwa cyane mubijyanye no guta amashanyarazi, gukwirakwiza anti-ruswa, guhuza ibyuma nibindi kubera imbaraga zayo zihuza cyane, ubuso bwagutse, kugabanuka guke, guhagarara neza, gukomera kwamashanyarazi, imbaraga za mashini nyinshi kandi uburyo bwiza.Mu myaka yashize, epoxy UV ikiza resin nkinganda zateye imbere.
Ariko, kuri ubu, guhangana nikirere cyibicuruzwa byinshi bya epoxy biracyafite intege nke cyane cyane mubikorwa byo gufata epoxy yometse, yayoboye inkono, epoxy UV ikiza resin imitako yimitako, nibindi, ibisabwa nibara ryibicuruzwa birakomeye, nabyo bishyira hejuru cyane ibisabwa kubikorwa byo kurwanya umuhondo wa sisitemu ya epoxy.
Hariho ibintu byinshi bitera umuhondo wibicuruzwa bya epoxy: 1. Bisifenol imiterere ya aromatic epoxy UV ikiza resin iroroshye okiside kugirango itange karubone kugirango ibe itsinda ryumuhondo;2. Ibigize amine yubusa mubikoresho byo gukiza amine bihindurwamo polimerike na epoxy UV ikiza resin, bigatuma ubushyuhe bwaho bwiyongera kandi umuhondo wihuta;3. Umuvuduko wa amine wihuta hamwe na moteri yihuta ya nonylphenol biroroshye guhindura ibara munsi ya ogisijeni ishyushye hamwe na irrasi ya UV;4. Niba ubushyuhe buri hejuru cyane mugihe cyo kubyitwaramo, umwanda usigara hamwe na catalizator yicyuma muri sisitemu bizatera umuhondo.
Igisubizo cyiza nukongeramo antioxydeant na ultraviolet absorber, ishobora gukumira no gutinda umuhondo.Nyamara, hari ubwoko bwinshi bwa antioxydants, kandi guhitamo ibicuruzwa bikwiye bisaba ubufasha bwa tekiniki hamwe nuburambe bwo kwegeranya.
Gutondekanya antioxydants: imwe ni antioxydeant nyamukuru: gufata peroxide radicals yubusa, cyane cyane ibuza antioxydants ya fenol;Imwe murimwe ni antioxydants ifasha: kubora hydroperoxide, cyane cyane est est fosifite na thioester.Muri rusange, antioxydants zitandukanye zirasabwa ukurikije inzira yumusaruro, ibikoresho fatizo, umusemburo, inyongeramusaruro hamwe nuwuzuza ibicuruzwa bitandukanye, icyiciro cyumuhondo nu rwego rwumuhondo.
Umucyo Ultraviolet nawo nyirabayazana w'ingenzi utera okiside umuhondo wa sisitemu ya epoxy, cyane cyane ituruka ku zuba.Kubwibyo, cyane cyane kubakiriya bafite ibicuruzwa bigomba gukoreshwa hanze, tuzasaba ko hongerwaho umubare munini wa UV yinjira mubicuruzwa, bishobora kwinjiza UV no gutinda umuhondo.Byongeye kandi, gukoresha ultraviolet na antioxydeant birashobora gukina ingaruka, hamwe ningaruka yuko 1 plus 1 irenze 2.
Birumvikana ko gukoresha antioxydants hamwe na ultraviolet ikurura ntibishobora gukemura byimazeyo ikibazo cyumuhondo, ariko mugihe runaka kandi mugihe runaka, birashobora gukumira neza okiside yumuhondo wibicuruzwa, kugumana ibara ryamazi yibicuruzwa mu mucyo no kuzamura urwego rwibicuruzwa .
