Tikanga mo te tango hinu i te mata o te ngongo tapawha

Kare e kore ka pania te mata o te ngongo tapawha ki te hinu, ka pa ki te kounga o te tango waikura me te phosphating. I muri mai, ka whakamaramahia e matou te tikanga mo te tango hinu i runga i te mata o te ngongo tapawha i raro nei.

he paipa tapawha kua hinuhinu

(1) Te horoi whakarewa pararopi

Ko te nuinga o te whakamahi i nga whakarewa pararopi ki te whakakore i te hinu saponified me te hinu kore ki te tango stains hinu. Ko nga whakarewa waro e whakamahia nuitia ana ko te warowaiha, te hinu horoi, te toluene, te tetrachloride waro, te trichloroethylene, me etahi atu. Me tohu ko muri i te tango hinu ma te whakarewa pararopi, me mahi ano te tango hinu taapiri. A, no te pähekeheke te whakarewa i runga i te mata o tengongo tapawhā, i te nuinga o te waa he kiriata angiangi e toe ana, ka taea te tango i nga mahi e whai ake nei penei i te horoi alkali me te tango hinu hiko.

(2) Te horoi matū hiko

Ko te tango hinu Cathode, te whakamahi rereke ranei o te anode me te cathode he mea nui ake te whakamahi. Ko te hau hauwai i wehea mai i te cathode, te hau hāora ranei i wehea mai i te anode e te tauhohenga hiko matū ka whakakorikoria e te otinga i runga i te mata o tengongo tapawhāki te whakatairanga i te poke hinu ki te mawhiti i te mata whakarewa. I te wa ano, ka whakawhiti tonu te otinga, he pai ki te tauhohenga saponification me te emulsification o te hinu. Ko te toenga o te hinu ka wehea mai i te mata whakarewa i raro i te mana o nga mirumiru wehe tonu. Heoi, i roto i te tukanga o te whakakore i te cathodic, he maha nga wa ka uru te hauwai ki roto i te whakarewa, ka pakaru te hauwai. Hei aukati i te hauwai, ka whakamahia te cathode me te anode ki te tango hinu.

(3) Te horoi kawakore

He tikanga horoi i runga i te mahi matū o te kawakore e whakamahia nuitia ana na te ngawari o te whakamahi, te iti o te utu me te waatea o nga rawa mata. Mai tei te tukanga horoi alkali i runga i saponification, emulsification me ētahi atu mahi, e kore e taea te whakamahi i te alkali kotahi ki te whakatutuki i te mahi i runga ake. He maha nga momo waahanga ka whakamahia, ka taapirihia etahi taapiri penei i te surfactant i etahi wa. Ko te alkalinity e whakatau ana i te tohu o te tauhohenga saponification, a ko te kawakoretanga teitei ka whakaiti i te awangawanga o te mata i waenga i te hinu me te otinga, ka ngawari te hinu ki te emulsify. I tua atu, ko te kai horoi e toe ana i runga i te mata o tetapawhā tapawhā wāhanga kōhaoka taea te tango ma te horoi wai i muri i te horoinga alkali.

(4) Te horoi o te hau

He tikanga tango hinu e whakamahia nuitia ana ma te whakamahi i nga ahuatanga o te surfactant penei i te iti o te awangawanga o te mata, te makuku pai me te kaha whakaemulsifying kaha. Na roto i te emulsification o te surfactant, e hamanihia te hoê tapo‘i mata interfacial e te tahi mau puai i nia i te afata hinu-pape no te taui i te huru o te afata, ia marara te mau hu‘ahu‘a hinu i roto i te vairaa pape no te hamani i te emulsion. Na roto ranei i te mahi memeha o te surfactant, te poke hinu e kore e rewa i roto i te wai i runga i tengongo tapawhāka rewa i roto i te micelle surfactant, kia taea ai te whakawhiti i te paru hinu ki te wairewa wai.
