Ibiranga UV ikiza resin

Igizwe na monomer na oligomer kandi ikubiyemo amatsinda akora.Irashobora gutangiza polymerisiyasi yakozwe nuwatangije urumuri munsi ya UV irrasiyo kugirango ikore firime idashonga.Umucyo ukize, uzwi kandi kwizina rya fotosensitif, ni oligomer ishobora guhinduka vuba mumubiri na chimique mugihe gito nyuma yo kurasirwa numucyo, hanyuma igahuza igakira.UV ikiza resin ni ubwoko bwamafoto yumubyimba ufite uburemere buke bwa molekile.Ifite amatsinda adasubirwaho ashobora kuba UV ashobora gukira, nkibice bibiri bidahagije cyangwa amatsinda ya epoxy.UV ikiza resin ni matrix resin ya UV ikiza.Yiyongereye hamwe na fotoinitiator, ikora cyane ninyongeramusaruro zitandukanye kugirango ikore UV ikiza.

UV ikiza resin igizwe na monomer na oligomer.Irimo amatsinda akora kandi irashobora gutangiza polymerisiyasiyo itangizwa numucyo utangiza munsi ya UV irrasiyoya kugirango ikore firime idashonga.Bisphenol Acrylate ya epoxy ifite ibiranga umuvuduko ukiza vuba, imiti irwanya imiti hamwe nubukomere bukabije.Polyurethane acrylate ifite ibiranga guhinduka neza no kwambara.Umucyo ukize wibikoresho bya resin nibisanzwe bikoreshwa mukuzuza no gusana ibikoresho mumashami ya Stomatology.Kubera ibara ryiza ryayo nimbaraga zimwe zo kwikomeretsa, igira uruhare runini mugukoresha amavuriro.Twageze ku bisubizo bishimishije mugusana inenge zitandukanye nu mwobo w amenyo yimbere.

Kugereranya kuvura umunwa

Kubice binini byimbitse, uburyo bwinshi bwo kugarura ibintu bifite inyungu zabyo nibibi: amalgam ifite ubukana bwinshi no kurwanya kwikomeretsa gukomeye, ariko ntigifatika (nta gukwega inzira ebyiri), gusa ishingiye kumashini, ifite kunyerera, kandi ifite kwangirika hamwe n'uburozi.Isesengura ryibintu byashonze byerekana ko Merkuri, ifeza, umuringa na zinc bishonga [2];Isima ya ionomer ciment ifata neza, ariko ifite ubukana bubi, ntabwo irwanya kwambara kandi byoroshye guhindura ibara;Gusana inlay (harimo alloy, plastike na farufari) gusana, gusana ikamba ryimbere yikamba, gusana ikamba ryicyuma hamwe na farufari yahujwe no kugarura ikamba ryicyuma bikoreshwa cyane mubikorwa byubuvuzi, ariko gutegura amenyo bifite imyenda nini, inzira igoye kandi ihenze cyane.

UV ikiza ikomatanya resin ikoreshwa cyane mumavuriro.Ifite imikorere myiza, nziza kandi irambye, imikorere yoroshye, igiciro gito kandi irazwi cyane.Ariko resinensitive resin ifite Phototropism.Uburyo bwuzuye bwo kuzuza mu kanwa bwemejwe, kandi isoko yumucyo iva mu cyerekezo kimwe, byanze bikunze bitera ko resin polymerisation yo hepfo no kurukuta rwubuvumo itameze neza nkubuso, bikavamo gucikamo ihuriro. y'amenyo yo hepfo [3].Ubushakashatsi bumwe bwerekanye ko urugero rwo gukiza rwa resin nyuma yo gukira urumuri ari 43% ~ 64% [3].Mubyukuri, abuzuza nkabo bakina 1/2 ~ 2/3 byimitungo yabo.Kugirango iki kibazo gikemuke, kuzuza ibice (mm 2 kuri buri cyiciro) mubisanzwe bikoreshwa mugukiza urumuri mumavuriro, ariko buri cyiciro cyubu buryo gihura nibidukikije bitose mumyanya yumunwa, bityo hakaba hari igipande cya n- 1 "ibice" mukuzuza ni ibice bimwe.Ubu irakoreshwa cyane muri coatings na wino.
