Quaternary Ammonium Cusbada ee jeermiska disha

Quaternary ammonium salts (QAS) waa isku-dhisyo cationic ah oo ay ku jiraan kooxaha alkyl ee silsiladda dhererkeedu yahay C8-C18, kuwaas oo ah biyo milmay waxaana loo isticmaali karaa jeermiska dila warshadaha dharka.

QAS waa xeryahooda ionic oo leh amooniyam afar geesle ah, afar kooxood oo alkyl ama aryl ah oo ku xiran nitrogen-kan, iyo ion anionic sida chloride ama bromide. Afar kooxood oo alkyl ah, mid waa koox silsilad alkyl dheer oo ka kooban in ka badan siddeed hydrocarbons iyo sidoo kale u adeega sida kooxda hydrophobic. Kooxaha Hydrophobic ee QAS waxay u muuqdaan inay saameeyaan shaqadooda ka hortagga jeermiska (Tiller et al., 2001; Zhao iyo Sun, 2007). Hydrophobicity xoog leh, hawlaha antimicrobial ka awood badan ee QAS waxay leedahay (Zhao iyo Sun, 2008) (Jaantus. 16.1 iyo Shaxda 16.1). Qaar badan oo ka mid ah xeryahooda QAS waxay leeyihiin shaqooyin surfactant ah. QAS waa biocides waxtar leh marka loo isticmaalo xalalka aqueous iyo sida jeermiska dareeraha ah. Marka QAS kiimiko ahaan loogu xidho sagxadaha fiber-ka hawlahooda waa la hor istaagi karaa iyadoo ku xidhan sida ay isugu xidhan yihiin iyo qaabka ugu dambeeya ee QAS ee sagxadaha. Jir ahaan QAS lagu daray fiilooyinka waxay bixin kartaa hawlaha antimicrobial iyadoo si tartiib tartiib ah looga sii daayo dusha fiberka inta lagu jiro isticmaalka, kaas oo bixin kara hawlaha loogu talagalay alaabta.
