Waa maxay xabagta UV ee la daweyn karo?

Xabagta daawaynta iftiinka waxay ka kooban tahay monomer iyo oligomer, kuwaas oo ka kooban kooxo firfircoon oo firfircoon waxaana lagu polymerized by curiyaha iftiinka hoostiisa iftiinka ultraviolet si uu u dhaliyo filim aan la milmi karin.Xabagta la sawiran karo, oo sidoo kale loo yaqaan 'photosensitive resin', waa oligomer kaas oo ku dhici kara isbeddello jireed iyo kiimiko waqti gaaban ka dib markii uu iftiimo, ka dibna isku xidhka iyo daaweynta.Xabagta UV ee la daweyn karowaa nooc ka mid ah xabagta sawir-qaadista oo leh miisaan unugyo qaraabo ah oo hooseeya, kaas oo leh kooxo fal-celin ah oo noqon kara UV la daweyn karo, sida bonds double ama kooxaha epoxy.Xabagta UV ee la daweyn karo waa xabagta matrixkaDahaarka UV ee la daweyn karo.Waxaa lagu daraa sawir-qaadayaal, dareerayaal firfircoon iyo waxyaabo lagu daro oo kala duwan si loo sameeyo dahaarka UV ee la daweyn karo.

Xabagta daawaynta iftiinka waxa ay ka kooban tahay resin monomer iyo oligomer, kaas oo ka kooban kooxo firfircoon.Waxaa lagu polymerized by hindise iftiin hoos ultraviolet iftiinka si loo dhaliyo filim aan la milmi karin.Bisphenol A epoxy acrylatewaxay leedahay sifooyinka xawaaraha bogsashada degdega ah, caabbinta dareeraha kiimikada wanaagsan iyo adkaanta sare.Polyurethane acrylatewuxuu leeyahay dabeecadaha dabacsanaanta wanaagsan iyo xirashada caabbinta.Xabagta isku dhafan ee khafiifka ah ee la daweeyay waa wax buuxinta iyo hagaajinta inta badan loo isticmaalo stomatology.Sababtoo ah midabkiisa quruxda badan iyo xoogaa xoogaa cadaadis ah, waxay door muhiim ah ka ciyaartaa codsiga kiliinikada.Waxaan gaadhnay natiijooyin lagu qanco oo hagaajinta cilladaha kala duwan iyo godadka ilkaha hore.

Dahaarka UV ee la daweyn karo waa dahaarka badbaadinta tamarta-saaxiibtinimo ee ay samaysay Shirkadda Bayer ee Jarmalka dabayaaqadii 1960-meeyadii.Shiinaha ayaa galay duurkaDahaarka UV ee la daweyn karoilaa 1980-aadkii.Marxaladda hore, wax soo saarka xabagta daweynta UV waxaa inta badan sameeyay shirkado ay ka mid yihiin American Sadoma, Japanese synthetic, German Bayer iyo Taiwan Changxing.Hadda, warshado badan oo gudaha ah ayaa si fiican u shaqeynaya, sida Sanmu Group iyo Zicai Chemical.Sanadihii la soo dhaafay, iyada oo kor loo qaadayo wacyiga dadka ee ilaalinta tamarta iyo ilaalinta deegaanka, waxqabadka kala duwan ee dahaarka UV ee la daweyn karo ayaa si joogto ah loo wanaajiyey, goobta codsiga ayaa la ballaariyay, wax soo saarkuna si degdeg ah ayuu u kordhay, taas oo muujinaysa horumar degdeg ah.Gaar ahaan ka dib markii dahaarka lagu daro baaxadda cashuur ururinta isticmaalka, horumarinta resin UV [1] ayaa la filayaa inuu sii dardargeliyo.Dahaarka daweyn UV ma aha oo kaliya si ballaaran loo isticmaalo in warqad, balaastiig, maqaar, biraha, galaas, ceramics iyo substrates kale, laakiin sidoo kale si guul leh loo isticmaalo in fiber indhaha, guddiga wareegga daabacan, baakadaha qayb elektaroonik ah iyo qalab kale.
