Kodi utomoni wochiritsira wa UV ndi chiyani?

Utoto wochiritsa wowala umapangidwa ndi monomer ndi oligomer, zomwe zimakhala ndi magulu ogwira ntchito ndipo zimatha kupangidwa ndi ma polima pogwiritsa ntchito kuwala kwa ultraviolet kuti apange filimu yosasungunuka.Photocurable utomoni, yomwe imadziwikanso kuti photosensitive resin, ndi oligomer yomwe imatha kusintha kusintha kwa thupi ndi mankhwala pakapita nthawi yochepa itatha kuwala, ndiyeno crosslink ndi kuchiritsa.UV mankhwala utomonindi mtundu wa utomoni wa photosensitive wokhala ndi kulemera kochepa kwa mamolekyulu, omwe ali ndi magulu omwe amatha kukhala ochiritsika ndi UV, monga ma unsaturated double bonds kapena epoxy groups.Utoto wochiritsira wa UV ndi utomoni wa matrix waZovala zochiritsira za UV.Zimaphatikizidwa ndi ma photoinitiators, zosungunulira zogwira ntchito ndi zowonjezera zosiyanasiyana kuti apange zokutira zochiritsira za UV.

Utoto wochiritsa wopepuka umapangidwa ndi utomoni wa monomer ndi oligomer, womwe uli ndi magulu ogwira ntchito.Ikhoza kupangidwa ndi polymerized ndi kuwala koyambitsa kuwala pansi pa kuwala kwa ultraviolet kuti ipange filimu yosasungunuka.Bisphenol A epoxy acrylateali ndi makhalidwe achangu kuchiritsa liwiro, zabwino zosungunulira mankhwala kukana ndi mkulu kuuma.Polyurethane acrylateali ndi makhalidwe abwino kusinthasintha ndi kuvala kukana.Utoto wopangidwa ndi kuwala wochiritsidwa ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri podzaza ndi kukonza zinthu mu stomatology.Chifukwa cha mtundu wake wokongola komanso mphamvu zina zopondereza, zimagwira ntchito yofunika kwambiri pazachipatala.Tapeza zotsatira zokhutiritsa pokonza zolakwika zosiyanasiyana ndi zibowo za mano akutsogolo.

Chophimba chochizira cha UV ndi chotchingira choteteza mphamvu zachilengedwe chopangidwa ndi Bayer Company ku Germany kumapeto kwa zaka za m'ma 1960.China yalowa m'munda waZovala zochiritsira za UVkuyambira 1980s.Kumayambiriro koyambirira, kupanga utomoni wochizira UV kunapangidwa makamaka ndi makampani monga American Sadoma, Japanese Synthetic, German Bayer ndi Taiwan Changxing.Tsopano, opanga ambiri apakhomo akuchita bwino, monga Sanmu Gulu ndi Zicai Chemical.M'zaka zaposachedwa, ndi kupititsa patsogolo chidziwitso cha anthu pakusunga mphamvu ndi kuteteza chilengedwe, magwiridwe antchito osiyanasiyana a zokutira zochiritsira za UV zakhala zikuwonjezeredwa mosalekeza, gawo logwiritsira ntchito lakulitsidwa, ndipo zotulutsa zakula mwachangu, zomwe zikuwonetsa kukula mwachangu.Makamaka zokutirazo zikaphatikizidwa pakutolera misonkho, kupangidwa kwa utomoni wa UV [1] kukuyembekezeka kukwera kwambiri.Zovala zochiritsira za UV sizimagwiritsidwa ntchito kwambiri pamapepala, pulasitiki, zikopa, zitsulo, magalasi, zoumba ndi magawo ena, komanso zimagwiritsidwa ntchito bwino mu fiber kuwala, bolodi losindikizidwa, zotengera zamagetsi ndi zida zina.
