Umhlinzeki weBenzalkonium Chloride (BAC) eNingizimu Afrika

Iyini i-Benzalkonium Chloride?

I-Benzalkonium chloride (BAC, ADBAC — alkyl dimethyl benzyl ammonium chloride) iyi-quaternary ammonium compound (QAC) biocide — ingxube ye-alkyl chain homologues (C12–C16 dominant) e-amphiphilic (cationic surfactant character). I-BAC ibulala amabhaktheriya, isikhunta, kanye ne-algae ngokuphazamisa ubuqotho be-membrane yeseli: iqembu lekhanda le-cationic ammonium libopha ngogesi ezingxenyeni ze-membrane yebhaktheriya eshajeke kabi, kuyilapho i-alkyl chain ende ifaka ku-lipid bilayer, iphazamisa isakhiwo se-membrane, ibangele ukuvuza kokuqukethwe kwangaphakathi kweseli kanye nokufa kweseli. I-BAC iyasebenza ngokumelene nohlu olubanzi lwamabhaktheriya ane-gram-positive kanye ne-gram-negative, ama-fungi amaningi, kanye ne-algae, kodwa ikhombisa ukusebenza okulinganiselwe ngokumelene nama-spores ebhaktheriya kanye nama-mycobacteria.

Isicelo se-Biocide Yamanzi Apholile

Ekwelashweni kwamanzi okupholisa ezimbonini, i-BAC isetshenziswa njenge-biocide engagcini i-oxidizing ukulawula ukukhula kwamagciwane (kufaka phakathi i-Legionella pneumophila), ukwakheka kwe-algae, kanye nokuthuthukiswa kwe-biofilm ekupakisheni imibhoshongo yokupholisa, ukugcwalisa, kanye nobuso besitsha. I-BAC ivame ukuphakelwa njengomthamo we-slug (ukwelashwa kokushaqeka) ku-50-100 mg/L, iphindaphindwa ngezikhathi zeviki eli-1-2, noma njengokwelashwa okuqhubekayo kwezinga eliphansi (10-30 mg/L) kuye ngohlelo lokulawula i-microbiological. Iyahambisana namanye amakhemikhali amaningi okwelapha amanzi okupholisa futhi iyisici esijwayelekile ezinhlelweni zokuphathwa kwengozi ye-Legionella yemibhoshongo yokupholisa.

Ukubulala amagciwane okungaphezulu kanye nezinye izinhlelo zokusebenza

I-BAC iyisithako esibalulekile esisebenzayo kuma-disinfectants angaphezulu, ama-sanitiser, kanye nemikhiqizo yokuhlanza indawo eqinile yokunakekelwa kwempilo, ukucubungula ukudla, kanye nokusetshenziswa kwezikhungo. Isebenza ngokumelene ne-SARS-CoV-2 kanye namanye amagciwane ambozwe uma isetshenziswa ngamanani anconywayo. Ekwelapheni amanzi emanzini okuzijabulisa (amachibi, ama-spa), i-BAC isetshenziswa njengesithasiselo se-biocide. Ekwelapheni amanzi ase-oyili, ilawula amabhaktheriya anciphisa i-sulphate (SRB) kanye nokukhula kwamagciwane ajwayelekile ezinhlelweni zamanzi ezijova. I-Terracore Chemicals inikeza i-BAC ngokuqukethwe okusebenzayo okungu-50% no-80% kuma-drum angu-25 kg no-200 kg.
