Munyu weQuaternary ammonium (QAS) imakemikari ecationic ane mapoka ealkyl muhurefu hweC8–C18, ayo anonyungudika mumvura uye anogona kushandiswa semishonga yekuuraya utachiona mumaindasitiri emachira.
QAS imakemikari eionic ane quaternary ammonium nitrogen, mapoka mana ealkyl kana aryl akabatana nenitrogen iyi, uye anionic ion yakaita sechloride kana bromide. Pakati pemapoka mana ealkyl, rimwe boka refu realkyl chain rine mahydrocarbon anopfuura masere uye rinoshandawo seboka rehydrophobic. Mapoka ehydrophobic paQAS anowanzo kukanganisa mabasa avo eantimicrobial (Tiller et al., 2001; Zhao naSun, 2007). Nehydrophobic yakasimba, mabasa eantimicrobial ane simba zvikuru ane QAS (Zhao naSun, 2008) (Mufananidzo 16.1 neTafura 16.1). Mazhinji eQAS compounds ane mabasa esurfactant. QAS imishonga inoshanda kana ikashandiswa mumvura uye semishonga inouraya utachiona. Kana QAS yakabatana nemakemikari kune fiber surfaces mabasa ayo anogona kukanganiswa zvichienderana nekuti akabatana sei uye maumbirwo ekupedzisira eQAS pamusoro. QAS yakaiswa mumuviri mufibers inogona kupa mabasa ekuuraya utachiona nekuiburitsa zvishoma nezvishoma kubva pamusoro pefiber panguva yekushandiswa, izvo zvinogona kupa mabasa akagadzirirwa zvinhu izvi.
Kuisa pfungwa pachinhu chimwe chete kunokonzera kudzikira kwemabhakitiriya ne6-log panguva yekubatana
