Yintoni i-Oxalic Acid?
I-oxalic acid yeyona dicarboxylic acid ilula, efumaneka ngokwendalo kwizityalo ezininzi nokutya. Ukubaluleka kwayo kwezobugcisa kukwikhono layo lokwenza i-calcium oxalate precipitates enganyibilikiyo (isusa isikali secalcium) kwaye isebenze njengearhente yokunciphisa ethambileyo esusa amabala omhlwa ngokunciphisa i-Fe³⁺ iron kwimo ye-Fe²⁺ enyibilikayo, enokususwa emva koko. Olu dibaniso lokususa amabala kunye nokukwazi ukususa amabala entsimbi luyenza ibe yenye yezona khemikhali zisebenzayo zokususa amabala angengo-chlorine ezikhoyo.
Izicelo zokucoca nokulungisa
I-oxalic acid sisithako esisebenzayo kwizikhanyisi ezininzi zomthi, izicoci zeedekhi, kunye neemveliso zokulungisa amatye. Isusa i-tannin engwevu-mdaka kunye ne-iron staining kwimithi egugileyo ngaphandle kokutshabalalisa imicu yomthi, ibuyisela umbala wendalo ngaphambi kokuba ivalwe kwakhona okanye ipeyintwe. Kwiindawo zamatye kunye neethayile, isusa i-iron oxide kunye namabala okugqwala ajikeleza izixhobo zesinyithi, iindawo zokukhupha amanzi, kunye nentsimbi endala yokuqinisa. Kwishishini lempahla, i-dilute oxalic acid isusa amabala esinyithi kwimpahla.
Usetyenziso lwezoLimo noShishino
Kwimisebenzi yokufuya iinyosi, i-oxalic acid lunyango olubhalisiweyo lokulawula iVarroa mite. Kwimisebenzi yokulungisa isinyithi isetyenziselwa ukususa umhlwa kunye nezikali ngaphambi kokupeyinta okanye ukugaya i-galvanizing. Njenge-bleach yokunciphisa ikhuselekile kune-chlorine bleach kwii-substrates ezininzi ezinemibala. I-Terracore Chemicals inikezela nge-oxalic acid dihydrate yodidi lobuchwephesha kwiingxowa ezingama-25 kg zabavelisi beemveliso zokucoca, iingcali zokulungisa izakhiwo, kunye nabaprosesa bemizi-mveliso kulo lonke elaseMzantsi Afrika.
