Umhlinzeki we-Tetraacetylenediamine (TAED) eNingizimu Afrika

Kuyini i-TAED?

I-Tetraacetylethylenediamine (TAED) iyisiqalisi se-bleach esiphendula ne-hydrogen peroxide (kusuka ku-sodium percarbonate noma i-sodium perborate esixazululweni) ukuze ikhiqize i-peracetic acid endaweni ngesikhathi somjikelezo wokuwasha. I-Peracetic acid iyi-bleach esabela kakhulu kune-hydrogen peroxide uqobo, isebenza kahle emazingeni okushisa aphansi (30–40°C) lapho i-hydrogen peroxide yodwa ingasebenzi kahle ekukhanyeni. Lokhu kwenza i-TAED ibe yingxenye ebalulekile yezinsipho zesimanje zempuphu ezihlanganisiwe kanye namaphilisi okugeza izitsha okuzenzakalelayo.

Umsebenzi ku-Detergent Formulations

Izinhlelo zesimanje zokuhlanza izingubo ezisebenzisa amandla ngendlela engabizi zisebenza ku-30–40°C, lapho i-sodium percarbonate yodwa iphuma kancane kancane. I-TAED ivuselela ukufiphaza kulawa mazinga okushisa aphansi, ifinyelele ekususweni okuphumelelayo kwamabala etiyeni, ekhofini, ezithelo, nasewayinini ngaphandle kokudinga umjikelezo wokuwasha oshisayo. Isilinganiso sokufakwa esijwayelekile sicishe sibe yi-3:1 sodium percarbonate kuya ku-TAED ngesisindo ekuhlanganisweni kokugcina kwensipho. Kumaphilisi okuwasha izitsha okuzenzakalelayo i-TAED ihlanganiswa ne-sodium percarbonate ukuze inikeze amandla okuhlanza a-oxidative asusa amabala etiye nekhofi ezitsheni.

Ukunikezwa Nokuphathwa

I-Terracore Chemicals inikeza i-TAED exubile emasakeni angama-25 kg ukuze kuhlanganiswe izinto zokuhlanza ezimpushana kanye nokusebenza kokucindezela amaphilisi. I-TAED iyisandulela esithambile esinciphisa i-oxidation futhi kufanele igcinwe kude nomswakama kanye nezinto zokunciphisa ezingahambisani; ayihlukaniswa njengento eyingozi yokuthutha izimpahla ngesimo se-granular. Seluleka abakhiqizi bezinto zokuhlanza ngezilinganiso ezifanele ze-percarbonate:TAED kanye nezinketho ze-co-granulation zamafomethi ezinsipho ezincane nezincane.
