Xumbada melamine ee Yadina hydrophobic waxay ka samaysan tahay xumbo melamine jilicsan oo caadi ah taas oo la jarjaray oo si gaar ah loogu daaweeyay wakiilka hydrophobic, iyadoo heerka hydrophobic ka badan 99%.Waxaa lagu talinayaa in loo isticmaalo nuugista codka, dhimista qaylada, dahaarka iyo ilaalinta kulaylka ee markabka, diyaaradaha, hawada sare, baabuurta, iyo codsiyada dhismaha.
Marka la barbardhigo xumbo melamine jilicsan ee caadiga ah, Yadina hydrophobic melamine xumbo waxay leedahay qaab dhismeed isku mid ah iyo sifooyin gudaha ah.Waa unug aad u furan, walxo jilicsan oo jilicsan oo ololka dib u celisa oo laga sameeyay resin melamine sida matrixka oo lagu xumbeeyey xaalado gaar ah.Waxa ay bilaabataa in ay gubato oo kaliya marka ay taabato holac furan, isla markiiba way qudhuntaa si ay u soo saarto xaddi badan oo gaas ah oo aan shaqayn, kaas oo milo hawada ku hareeraysan, isla markaana si degdeg ah u samaysa lakab dhuxul ah oo dusha sare ah, si waxtar leh u go'doomiya ogsijiinta oo keenta ololka. in la is damiyo.Ma soo saarto dareere ama sunta molecules yaryar waxayna baabi'in kartaa khataraha badbaadada dabka ee xumbo-dhaqameedka polymer-ka.Sidaa darteed, iyada oo aan lagu darin ololka dib-u-celinta, xumbodani waxay gaari kartaa heerka B1 ee heerka walxaha ololka hooseeya (DIN4102) iyo heerka V0 ee heerka sheyga dab-demiska ololka sare (UL94) oo dejiyay heerka Ururka Caymiska Mareykanka.Intaa waxaa dheer, walxahan xumbo-ku-salaysan waxay leeyihiin qaab-dhismeed saddex-geesood ah oo leh heerka daloolka in ka badan 99%, kaas oo aan si wax ku ool ah u beddeli karin hirarka dhawaaqa tamarta gariirka oo uu cunaa oo uu nuugo, isagoo muujinaya waxqabadka xajinta dhawaaqa wanaagsan, laakiin sidoo kale si wax ku ool ah u xannibi kara wareejinta kulaylka convection hawo, oo ay weheliso xasilloonida kulaylka gaarka ah, taas oo ka dhigaysa in ay leedahay sifooyin kulaylka wanaagsan.
