Iibinta kulul ee aliphatic polyurethane acrylic polyurethane UV resin ayaa si weyn loogu isticmaalaa vacuum electroplating iyo buufin caag ah

ZC6523 waa polyurethane acrylate trifunctional ah oo lagu farsameeyay polymerization of polyester polyol, wakiilka daawada isocyanate aromatic iyo hydroxyethyl acrylate, oo sidoo kale loo yaqaanno resin daawo sawireed.Tilmaamaha farsamada: viscosity waa 5000-6000mpa S / 25 ℃, qiimaha acid <0.5 (NCO%), shaqeynta 3 (qiimaha aragtida), lambarka midabka: 1 # (Gardner);Alaabtani waxay leedahay faa'iidooyinka dabacsanaanta wanaagsan, xidhashada caabbinta, caabbinta xoqan, caabbinta kulaylka, caabbinta biyaha, dhaqdhaqaaqa falcelinta sare iyo wixii la mid ah.Waxaa si weyn loo isticmaalaa in beeraha khad lagu daweeyo iftiinka, alaabta alwaax, daahan sagxadda, daahan warqad, daahan caag ah, daahan fiber indhaha, daahan biraha iyo koollada.

Xabagta UV waxay u baahan tahay dahaar khafiif ah oo lagu sameeyo iyada oo lagu darayo dareere firfircoon, sawir-qaade, daroogo, midabyo iyo buuxinyaal, iyo nooc cusub oo daahan ah ayaa lagu samayn karaa shucaac UV dheeraad ah.Hababka dahaarka waxaa ka mid ah daahan rullaluistemadka, daahan drenching, buufinta, daahan faleebo iyo hababka kale.Faa'iidooyinka dahaadhkani waa ilaalinta deegaanka, dhismaha degdega ah (Fiiro gaar ah: kuma koobna cimilada, heerkulka iyo xaaladaha qoyaanka), iyo badbaadinta shaqada, Alaabooyinka la soo saaro waxay leeyihiin waxqabad aad u fiican iyo wixii la mid ah.

Unugyada polyurethane acrylate (PUA) waxay ka kooban yihiin kooxo hawleed akril ah iyo curaarta carbamate.Xabagta la daaweeyay waxay leedahay caabbinta xirashada sare, dhejinta, dabacsanaanta, xoogga diirka sare, iska caabinta heerkulka hooseeya ee poliurethane iyo sifooyinka wanaagsan ee indhaha iyo caabbinta cimilada ee polyacrylate.Waa shay lagu daweeyo shucaaca oo leh sifooyin dhammaystiran oo heersare ah.PUA waxay noqotay fasal aad muhiim u ah oligomers oo ku yaal goobta dahaarka aan biyuhu lahayn.Iyada oo ay ugu wacan tahay waxqabadka wanaagsan ee resin PUA, cilmi baarista PUA ayaa sidoo kale sii kordheysa.Polyurethane acrylate sidoo kale si tartiib tartiib ah ayaa loo koobiyeeyay noocyada kale ee resins si loo sameeyo nidaam isku-dhafan oo loo horumariyo habka biyaha.Gaar ahaan, nidaamka aqueous wuxuu si toos ah u isticmaalaa biyaha si loo milo oo loo yareeyo viscosity, taas oo ka dhigaysa daahan ka badan deegaanka saaxiibtinimo iyo caafimaadka iyo yaraynaysaa isticmaalka monomers firfircoon, Ilaa xad weyn, waxa ay ka dhigaysa la'aanta qiimaha qaaliga ah ee PUA resin. , kaas oo ballaarin kara kala duwan ee codsiga ee resin PUA, la yareeyo ama xitaa ha isticmaalin monomers, si wax ku ool ah u yareeyaan yaraynta daahan biyuhu, yareeyaan stress gudaha inta lagu guda jiro daaweynta, kordhiyo adhesion of daahan iyo hagaajinaysaa dabacsanaan ee daahan filimka.
