Te kaupapa me te whakamahinga o ngā demulsifiers

Nā te iti o te wairewatanga o ētahi matū totoka ki te wai, ina nui te rahinga o tētahi, o ētahi rānei o ēnei matū totoka i roto i te wairewa, ā, ka whakaohokia e ngā kaha waipēhi, e ngā kaha o waho rānei, ka noho tonu rātou i roto i te āhua o te whakapūhui i roto i te wai, ka hanga he whakapūhui. I roto i te ariā, he kore pumau tēnei pūnaha. Heoi, i te aroaro o ngā matū surfactants (pērā i ngā matūriki oneone), ka kaha te whakapūhui, ka uaua ake te wehewehe i ngā wāhanga e rua. Ka kitea nuitia tēnei i roto i ngā ranunga hinu-wai i te wā e wehea ana te hinu-wai, me ngā ranunga wai-hinu i roto i te maimoatanga wai para, kei reira ngā hanganga wai-i-te-hinu, hinu-i-te-wai rānei e hanga ana i waenganui i ngā wāhanga e rua. Ko te pūtake ariā mō tēnei āhuatanga ko te "hanganga paparua."

I roto i ēnei āhuatanga, ka whakaurua ētahi matū hei whakararuraru i te hanganga paparua pumau, hei whakararuraru hoki i te pūnaha whakaemulsified, ā, ka tutuki te wehenga o ngā wāhanga e rua. Ko ēnei kaihoko, e whakamahia ana hei wawahi i ngā whakaemuls, ka kiia he demulsifiers.

He matū hohe-mata te mea whakakore i ngā matū e whakararuraru ana i te hanganga o te wai kua whakaemuhia, ā, ka wehea ngā momo āhua i roto i te whakaemu. Te whakakore i ngā matū hinu mata e pā ana ki te tukanga o te whakamahi i te mahi matū a ngā demulsifier hei wehe i te hinu me te wai mai i te ranunga hinu-wai kua whakaemulsified, kia tutuki ai te maroke o te hinu mata kia tutuki ai ngā paerewa o te ihirangi wai e hiahiatia ana mō te kawe waka.

Ko te whakamahi i ngā mea whakakore i ngā matū hei whakakore i te whakaemulsion me te whakararuraru i te hanganga o tētahi atanga whakaemulsion kaha, ā, ka tutuki ai te wehenga wāhanga. Heoi, he rerekē te kaha o ngā mea whakakore i ngā matū ki te whakakore i ngā matū, ā, ka pā tika tā rātou mahi ki te whai huatanga o te wehenga wāhanga.

I roto i te hanga penicillin, ko tētahi mahi nui ko te tango i te penicillin mai i te hupa whakapūkara mā te whakamahi i tētahi whakarewa waro (pērā i te butyl acetate). Nā te mea kei roto i te hupa whakapūkara ngā matū matatini.—pērā i ngā pūmua, ngā huka, me ngā mycelia—Ka kore e mārama te hononga i waenga i ngā āhua waro me ngā āhua wai, ka hangaia he rohe emulsification taurite, ka pā nui ki te hua o te hua whakamutunga. Hei whakatika i tēnei, me whakamahi ngā demulsifiers hei wawahi i te emulsion, hei whakakore i te āhua emulsified, ā, hei whakatutuki i te wehenga āhua tere me te whai hua.
