Umthengisi weBenzalkonium Chloride (BAC) eMzantsi Afrika

Yintoni iBenzalkonium Chloride?

I-Benzalkonium chloride (BAC, ADBAC — alkyl dimethyl benzyl ammonium chloride) yi-quaternary ammonium compound (QAC) biocide — umxube we-alkyl chain homologues (C12–C16 dominant) ene-amphiphilic (cationic surfactant character). I-BAC ibulala iintsholongwane, iifungi, kunye ne-algae ngokuphazamisa ukuthembeka kwe-membrane yeseli: iqela le-cationic ammonium head libopha nge-electrostatically kwiinxalenye ze-membrane yebhaktiriya ezitshajwe kakubi, ngelixa i-alkyl chain ende ingena kwi-lipid bilayer, iphazamisa isakhiwo se-membrane, ibangela ukuvuza komxholo wangaphakathi kweseli kunye nokufa kweseli. I-BAC isebenza ngokuchasene noluhlu olubanzi lweentsholongwane zegram-positive kunye negram-negative, iifungi ezininzi, kunye ne-algae, kodwa ibonisa ukusebenza okuncinci ngokuchasene ne-spores zebhaktiriya kunye ne-mycobacteria.

Ukusetyenziswa kwe-Biocide yamanzi okupholisa

Kwindlela yokucoca amanzi okupholisa kwimizi-mveliso, i-BAC isetyenziswa njenge-biocide engangcolisiyo ukulawula ukukhula kwebhaktheriya (kubandakanya iLegionella pneumophila), ukwakheka kwe-algae, kunye nophuhliso lwe-biofilm kwiindawo zokupakisha iitower zokupholisa, ukuzalisa, kunye neendawo zokubeka amanzi. I-BAC idla ngokunikwa idosi ye-slug (unyango lomothuko) kwi-50–100 mg/L, iphindaphindwe kwiiveki ezi-1–2, okanye njengonyango oluqhubekayo oluphantsi (10–30 mg/L) ngokuxhomekeke kwinkqubo yolawulo lwe-microbiological. Ihambelana nezinye iikhemikhali zonyango lwamanzi okupholisa kwaye yinxalenye eqhelekileyo kwiinkqubo zolawulo lomngcipheko weLegionella kwiitower zokupholisa.

Ukubulala iintsholongwane kumphezulu kunye nezinye iindlela zokusetyenziswa

I-BAC sisithako esibalulekileyo esisebenzayo kwizibulali-ntsholongwane eziphezu komhlaba, izibulali-ntsholongwane, kunye neemveliso zokucoca umphezulu oqinileyo kwezempilo, ekulungisweni kokutya, nasekusetyenzisweni kwezikhungo. Isebenza ngokuchasene ne-SARS-CoV-2 kunye nezinye iintsholongwane ezigqunywe xa isetyenziswa kumanqanaba acetyiswayo. Kunyango lwamanzi emanzini okuzonwabisa (amachibi, ii-spa), i-BAC isetyenziswa njengesincedisi se-biocide. Kunyango lwamanzi ase-oyile, ilawula iintsholongwane ezinciphisa i-sulphate (SRB) kunye nokukhula ngokubanzi kweentsholongwane kwiinkqubo zamanzi ezifakwayo. I-Terracore Chemicals inikezela nge-BAC ngomxholo osebenzayo we-50% kunye ne-80% kwiidrama ezingama-25 kg kunye ne-200 kg.
