Horudhaca kooxaha shaqaynaya
Habka diyaarinta ee daahan Waterborne UV, kooxaha functional iyo qalfoof polymer ayaa si wadajir ah loo polymerized iyada oo loo marayo falcelinta synthetic.Kooxaha shaqada sida caadiga ah loo isticmaalo waa fluorine iyo siloxane.Ku darida kooxahan shaqeynaya waxay si wax ku ool ah u yareeyn karaan xiisadda dusha sare ee filimka la daaweeyay, waxay fududeynayaan isku dhejinta wanaagsan ee u dhexeeya daaha iyo dahaarka, iyo kordhinta adhesion u dhexeeya filimka rinjiga iyo substrate.Intaa waxaa dheer, sababtoo ah hydrophobicity xooggan ee kooxaha shaqeynaya sida siloxane, filimka rinjiga ayaa sidoo kale leh heerar gaar ah oo hydrophobicity ah, kaas oo si wax ku ool ah u wanaajiya waxqabadka biyaha-milla ee alaabta dhaqameed iyo hagaajinta caabbinta biyaha iyo caabbinta dareeraha ee filimka rinjiga.
Xoojinta habka daaweynta
Guud ahaan, dahaarka UV ee Waterborne way adag tahay in la daweeyo, gaar ahaan marka loo isticmaalo hababka midabka leh ama dahaarka qaro weyn.Waxaa intaa dheer, sababtoo ah ku darida sawir-qaade, daaha Waterborne UV waa sahlan tahay in lagu daaweeyo shucaaca ultraviolet.Si kastaba ha ahaatee, marka daahan loo isticmaalo qalab aad u adag, shucaaca ultraviolet ee daahan Waterborne UV waa mid aan dhamaystirnayn, taas oo ka dhigaysa qaar ka mid ah dahaarka ay adag tahay in la daweeyo.Sidaa darteed, marka loo eego xaaladda hadda jirta, cilmi-baarayaashu waxay soo saareen nidaam daaweyn oo badan oo lakabyo ah oo ka mid ah dahaarka UV Waterborne, kaas oo si wax ku ool ah u xalliya xaddidaadda daboolka UV ee Waterborne iyo ballaarinta kala duwanaanta codsiga ee daboolka.
Isticmaalka nidaamka kharashaadka
Sababtoo ah waxaa jira kooxo badan oo kaarboxyl ah oo ku jira daahan Waterborne UV, miisaanka unugga qaraabo ee kooxdani waa weyn yahay.Sidaa darteed, viscosity ee daboolka Waterborne UV waa mid aad u weyn, taas oo yaraynaysa maadada adag ee daahan, taas oo saameyn xun ku leh filimka rinjiga waxayna yareysaa dhaldhalaalka iyo caabbinta biyaha ee filimka rinjiga.Sidaa darteed, si loo hagaajiyo dhacdadan, cilmi-baarayaashu waxay dejiyeen nidaam hyperbranched ah oo ku yaala Waterborne UV daahan, waxay hagaajiyeen caabbinta biyaha ee filimka rinjiga iyada oo loo marayo kooxo waaweyn oo shaqeynaya, waxayna isticmaaleen sifooyinka qaabdhismeedka oligomers si loo yareeyo viscosity nidaamka iyo hagaajinta gloss ee filimka rinjiga.
Marka la soo koobo, iyada oo ay ugu wacan tahay gaar ahaan walxaha ka kooban dahaarka Waterborne UV, waxay leedahay faa'iidooyin gaar ah marka loo eego dahaarka dhaqanka.Sidaa darteed, daahan Waterborne UV waxaa si weyn loogu isticmaalaa alwaax iyo varnish warqad.Sababo la xiriira horumarka aan qummanayn ee daahan Waterborne UV, cilmi-baarayaashu wali waxay hagaajinayaan waxqabadka dahaarka Waterborne UV, iyagoo ku daraya kooxo shaqeynaya daboolka iyo sameynta nidaamka daaweynta lakabyada badan.Intaa waxaa dheer, Isticmaalka nidaamka hyperbranched ee dahaarka waa jihada cilmi-baarista mustaqbalka ee Waterborne UV daahan.Iyadoo loo marayo hagaajinta joogtada ah ee daahan Waterborne UV, waxay yeelan karaan sunta hoose, adkaanta iyo dhaldhalaalka qumman.
