Cusbo Ammonium Quaternary ah oo loogu talagalay jeermiska dila

Cusbooyinka ammonium ee Quaternary (QAS) waa iskudhisyo cationic ah oo ka kooban kooxo alkyl ah oo dhererkoodu yahay C8–C18, kuwaas oo biyo ku milma waxaana loo isticmaali karaa jeermis dile warshadaha dharka.

QAS waa iskudhisyo ionic ah oo leh nitrogen ammonium quarternary ah, afar kooxood oo alkyl ama aryl ah oo ku xiran nitrogen-kan, iyo ion anionic ah sida chloride ama bromide. Afar kooxood oo alkyl ah, mid waa koox silsilad alkyl dheer ah oo ka kooban in ka badan siddeed hydrocarbons waxayna sidoo kale u adeegtaa sidii kooxda hydrophobic. Kooxaha Hydrophobic ee ku jira QAS waxay u muuqdaan inay saameeyaan shaqadooda antimicrobial (Tiller et al., 2001; Zhao iyo Sun, 2007). Iyada oo leh hydrophobic xooggan, shaqooyinka antimicrobial ee awoodda badan ee QAS leeyahay (Zhao iyo Sun, 2008) (Jaantuska 16.1 iyo Shaxda 16.1). Iskudhisyo badan oo QAS ah ayaa leh shaqooyin surfactant ah. QAS waa biocides wax ku ool ah marka loo isticmaalo xalalka biyaha iyo sida jeermiska dila dareeraha. Marka QAS si kiimiko ah loogu xiro dusha sare ee fiber-ka, shaqooyinkooda waa la carqaladeyn karaa iyadoo ku xiran sida ay isugu xiran yihiin iyo qaab-dhismeedka ugu dambeeya ee QAS dusha sare. QAS-ka jirka ku jira ee fiilooyinka ayaa bixin kara shaqooyin antimicrobial ah iyadoo si tartiib tartiib ah looga sii daayo dusha sare ee fiber-ka inta lagu jiro isticmaalka, taas oo bixin karta shaqooyinka loogu talagalay agabka.
