Silsiladda fidiyaha iyo emulsifier ee kala firidhsanaanta polyurethane aqueous.Waa milix sodium aliphatic diamine sulfonic acid, oo loo isticmaalo sidii silsiladda silsiladaha hydrophilic ama monomer hydrophilic ee diyaarinta resin polyurethane ee biyaha ka dhasha, oo ku habboon dahaarka, khadadka, koollada iyo wakiilada dhamaystirka maqaarka iyo warshadaha kale.Sodium ethylenediaminoethanesulfonate sidoo kale waxaa loo isticmaali karaa meelo kale sida dhexdhexaadiyeyaasha organic iyo reagents biochemical.Mawqifkeeda X iyo kooxaha amino-booska labaad waxay la falcelin karaan kooxaha isocyanate waxaana inta badan lagu taliyaa in loo isticmaalo habka acetone.Kala firdhisyada polyurethane ee lagu farsameeyay iyadoo la isticmaalayo cusbada AAS waxay leeyihiin xasillooni hydrolytic wanaagsan iyo waafaqid wanaagsan oo leh kala firdhinta aqueous kale ee anionic ama nonionic.
