Te hanganga ongā matū horoihe tino māmā noa iho: he pai ki te wai tetahi pito (he wai-aroha) me tetahi atu he lipophilic (hinu-(aroha). Ka herea ia pito ki tōna hoa, ki te wai me te hinu. Ka huihui ngā ngota surfactant ki te hinu-te atanga wai, ā, koinei te whakatakotoranga taketake. Ko te emulsification tētahi o ngā mahi a ngā surfactants, engari koia te mea tino whānuitia-he mahi e whakamahia ana i roto i tā mātou umanga. Ko te nuinga o te wā ka whakamahia mō te whakaranu wai-ngā hinu i ahu mai i te wai, pērā i ngā hinu me te wai kua whakaemulhia-kei roto te ahi-ngā wai waipēhi ātete. Heoi anō, he whānui rawa ngā whakamahinga o ngā emulsifier i ia rā-ngā hua ora tae atu ki te miraka, te hukapapa-he kirīmi me he hopi horoi makawe, he rerekē ngā taumata o ngā emulsifier kei roto i ēnei katoa.
Nā tēnei hanganga ngota ngota māmā, he maha ngā matū e whakaatu ana i ngā āhuatanga whakaemulsifier, ā, he tino uaua te whiriwhiri i te emulsifier. Ka taea te kī, ki te kore he māramatanga pai ki ngā emulsifier, e kore e taea te whakawhanake i te wai kounga teitei.-ngā hua hinu whakahinuhinu. E mōhiotia whānuitia ana kāore e taea te whakaranu i te hinu me te wai. Nō reira, me whakamahi ngā emulsifier hei whakakotahi i a rāua. I roto i tēnei whakakotahitanga kaha, ka huri tetahi wāhanga hei pata wai iti, ko tetahi atu wai ka kapi katoa i ēnei pata. Nā tēnei ka ara ake ngā ariā o te wāhanga tonu me te wāhanga marara: ka pakaru tetahi wāhanga hei pata kore tonu, ā, ko tetahi ka hanga he reo tonu kore mutu. Mā te tirohanga whānui, ka puta he wai-in-hinu (W/O) hinu rānei-in-ngā whakaemulsion wai (O/W). Kei roto i tēnā ngā mātāpono matua o ngā emulsifier.
Ina hekaiwhakaranuka whakaurua ki roto i te hinu kore e taea te whakaranu-I roto i te pūnaha wai, ka hangaia he tikanga marara hou hei whakaranu i ngā wāhanga e rua. Ehara tēnei i te rewatanga tūturu, arā, ko te tote e rewa ana i roto i te wai. Engari, ka marara ōrite tetahi wāhanga hei pata iti i roto i tetahi atu wāhanga. Mena ka rerekē ngā āhuatanga o waho, ka wehe anō te hinu me te wai, e tohu ana i te ngoikore o te emulsification, i te kore rānei o te pumau o te emulsion. Ka taea e ētahi tāpiri te whakararuraru i te hinu.-te taurite wai, ā, ka tīmata te wehenga katoa o ngā wāhanga; ka mahi ēnei matū i runga i te ātete ki ngā emulsifier, ā, e mōhiotia ana ko ngā demulsifier.
He pūnaha marara te emulsion. Nā te mea kua marara-ngā pata āhuahanga me ngā rerekētanga o te taupū whakaata i waenga i ngā āhuahanga, ka whakaatahia, ka mararahia, ka tukuna hoki te māramatanga taunga ki ngā mata pata. Ko te rahi o ngā pata emulsion noa kei waenga i te 0.1μm ki te 10μm, ahakoa e kitea ana-ka taka ngā roangaru mārama ki waenganui i te 0.4μm me te 0.6μm. Ka puta he whakaata kaha, ka hoatu he āhua miraka ki ngā emulsions-he mā te āhua. Ina tae te diameter o te pata ki te 0.05μm ki te 0.1μm (he iti ake i te mea e kitea ana-(ngā roangaru mārama), ka puta te marara o te mārama, ā, ka kitea te pūnaha he mārama. I ngā rahi o te pata i raro i te 0.05μm (he iti rawa atu i te mea e kitea ana-(ngā roangaru mārama), ka kaha te tuku mārama, ā, ka mārama te pūnaha. Ngā pūnaha he iti iho i te 0.1 te rahi o ngā pataμKo ngā mea e āhua mārama ana, e mārama ana rānei, e tautuhia ana ko ngā microemulsions, ā, he rerekē rawa ō rātou āhuatanga i ngā macroemulsions tikanga. He emulsion tonu te microemulsion, engari he pai ake te marara.-ngā pata wāhanga. Ehara i te mea ko ngā emulsifier anake te mea e hiahiatia ana mō tōna hanganga engari ko ngā mahi tahi anō hoki-ngā kaiwhakarewa. E whakaatu ana tēnei ko te whakarewa-peia"te whakakorenga"ko te mea nui ko te whakahaere i te rahi o te matūriki o te wāhanga marara.
Ko te mahi a te emulsifier e whakawhirinaki ana ki te taurite ngawari. Ko ōna kaha hydrophilic me lipophilic ka hanga he pānga piupiu. Hei tauira, he iti-He kaha te waiora o ngā waipiro waro, ā, ka rewa ki te wai me te iti noa o te kaha ki te hinu. I tetahi atu taha, kāore e taea e ngā matū tino lipophilic te taunekeneke ki te wai, te whakaatu rānei i te hinu.-whanonga wairewa. Ahakoa he maha ngā matū he wāhanga hydrophilic me lipophilic, kāore e taea te whakarōpū hei surfactants. Mena he matū hydrophilic, lipophilic rānei, he mata noa iho-te matū hohe, pērā i ētahi o ngā tāpiringa kua whakahuatia i runga ake nei. He inenga ine mō te hydrophilic-nō reira, e hiahiatia ana te kaha o te lipophilic, arā, te puna-mōhiotia he Hydrophile-Ngāwari ki te whakamahi-Uara toenga (HLB).
He aratohu whai hua te uara HLB mō te whakaemulsification mahi, me ngā tikanga whakamātautau maha, kua tuhia ki ngā tuhinga, ā, e kore e whakamāramahia i konei. Ehara i te mea uaua te whakaemulsifying hinu me ngā emulsifier. Ka taea te whakatau i ngā momo emulsifier tino pai, ngā horopeta me ngā āhuatanga pumau mā te whakamātautau.-me-hapa. Nō reira, ko te whanaketanga o te emulsifier e whakawhirinaki nui ana ki ngā mahi whakamātautau. He maha ngā moroiti-Kāore anō kia tino māramahia e ngā kairangahau ngā tikanga taumata o te whanonga o te surfactant tae noa mai ki tēnei rā. Haunga te emulsification, ka tukuna e ngā surfactants te makuku, te horoi, te horoi, te horapa, te whakarewa me ētahi atu mahi. Mō tā mātou umanga, he huarahi mahi te tirotiro whakamātautau, nā te mea ka ahu mai te mōhiotanga pono i te mahi. He maha ngā ture wheako kua whakatūria mā te whakamātautau: he pai ake ngā emulsifiers whakaranu i ngā emulsifiers takitahi, me ngā huinga o te anionic me te non-Ka whakaputa ngā matū horoi ionic i ngā pānga mahi tahi pai.
Ahakoa te māmā noa o te ariā o te emulsifier, he uaua te whakamahinga mahi. Mā te whakamahi i ngā emulsifier anake ka taea te whakatau mā te whakamātautau, engari he maha ngā mea i muri mai-he mata kei ngā tāpiringa kua tāpirihia-ngā āhuatanga hohe. Ka whakararuraru ēnei i te mahi a te emulsifier, ā, ka whakarerekē i te HLB whai hua o te pūnaha. Ko tētahi tauira noa ko ngā aukati waikura i roto i ngā emulsion. Ko ēnei mata tino polar-Kua whakauruhia ngā kai hohe hei ārai i te waikura engari ka taea te whakararu i te hinu-te taurite wai whakapūkara, ā, me whai whakaaro ki te wā e whiriwhiri ana i ngā whakapūkara. Mā te hanga ranunga o ngā momo whakapūkara maha ka taea te whakaiti i te horopeta me te utu, me te whakarei ake i te pumau o te whakapūkara. Heoi, ko ngā pātai e pā ana ki te whakakotahi i ngā whakapūkara rerekē me ā rātou tikanga whakaranu ka tino whakapiki i te uaua o te hanganga. He whakaaro hē tonu e kī ana kāore e taea te whakaranu i ngā whakapūkara anionic me te cationic. Inaa, ko te anionic-E whānuitia ana te pūrongo mō ngā ranunga surfactant cationic i roto i te pūtaiao surfactant, ahakoa he onge te whakamahi i roto i tā mātou rāngai. Tērā pea ka whakararuraru ngā katote konupūmā me te konupora kei roto i te wai mārō i ngā kiriata atanga emulsion me te whakakore i ngā emulsifier. He tino raruraru ngā katote konupūmā: he maha ngā emulsifier surfactant e tauhohe ana ki te konupūmā hei hanga wai.-ngā hopi konupūmā kore-rewa e puta mai ana i te pūnaha. Ka matapakihia tēnei kaupapa i te upoko e whai ake nei.
Nō reira, ka tino uaua ngā emulsifiers e ahua māmā ana ina whakaurua mai ētahi atu wāhanga. Ehara i te mea uaua te hanga i tētahi emulsion kua oti; ko te wero tūturu kei te pupuri i te pumau i raro i ngā āhuatanga ratonga rerekē, me te pupuri i te hinu me te wai kia piri tonu.
Ngā whakaritenga mahi mō ngā emulsifiers:
Ātete wai mārō
Ka tautuhia e tēnei tawhā te emulsifier'te manawanui ki te wai mārō. Ko ngā surfactants anionic tuku iho he iti te mahi i tēnei āhuatanga, nō reira kāore-Kei te whakakapia haeretia ēnei e ngā matū horoi ionic. Heoi anō, kei te mau tonu ngā painga ahurei o ngā matū horoi anionic.
Te āhua o te pahuka
He maha ngā matū horoi anionic tuku iho e whakaputa ana i te pahuka nui, e whakatairanga ana i te whakapono hē ko te nui o te pahuka he rite ki te pai o te horoi. Ko ngā matū horoi te mea nui e puta ai te pahuka. I roto i tā mātou hinu whakahinuhinu-i roto i ngā umanga e pā ana, he mea tino hiahiatia te iti o te pahuka. Heoi, he maha ngā emulsifier e whakaatu ana i te kaha pahuka teitei. Nō reira, me whiriwhiri e ngā kaihanga ngā taumata emulsifier tika hei pehi i te hanganga pahuka, e whakamārama ana i te pikinga o te hiahia mō te pera-i huaina he iti-ngā kaiwhakarewa pahuka.
Te pumau o te koiora
Ko te pumau koiora tētahi atu taupū mahi nui mō ngā emulsifier. Mena ka ngawari te emulsifier ki te pirau huakita i roto i te wā roa-mō te wā roa o te ratonga, ka tino raruraru te whakakorenga o te wai tapahi e rite ana. Te Taiao-He mana nui tō ngā ture tiaki ki te kōwhiringa o ngā emulsifier, ā, e whakahaere ana hoki i te umanga katoa.
Ka whakarōpūtia ngā emulsifier ki te anionic, te cationic, te amphoteric, me te non-ngā whānau ionic me ētahi atu, e rite ana ki ngā matū motuhake e mōhiotia ana e te hunga matatau-ngā tohunga matū. Kāore tēnei tuhinga e ruku hohonu ki ngā whakaahuatanga taipitopito rongonui o ia kāwai. I roto i tā mātou umanga, ko te anionic me te kore--Ko ngā emulsifiers ionic te mea nui rawa atu i runga i te whakamahinga me te kanorau o ngā hua. Kei roto i ia kāwai he maha ngā hanganga ngota ngota me ngā āhuatanga emulsifying rerekē, ia ia he kaha me ōna ngoikoretanga. He maha tonu te whakaranu i ēnei hei whakaiti i te horopeta whakamahinga me te whakapai ake i te pumau o te emulsion.
Kāore he ture pumau mō te hanganga o te emulsifier. Kei roto i ngā taurangi ko ngā rerekētanga o te turanga-hinu ki-be-whakaemulsified, ōwehenga ranunga emulsifier, ratonga-ngā āhuatanga taiao, ngā whakaritenga motuhake a te kiritaki, me ngā pānga taunekeneke mai i ētahi atu tāpiringa. Heoi anō, he otinga whai hua te whakamātautau. He ngāwari noa iho te whakahaere i ngā whakamātautau emulsification. Ahakoa kāore he papamuri ariā, ka taea e te tangata te tae ki ngā whakatakotoranga whai hua mā roto i ngā whakamātautau maha, ahakoa he utu wā. Te matū horoi e tika ana-he pai ngā ariā pūtaiao, e tere ake ai te whanaketanga-kua tuhia ki roto i ngā tuhinga o nāianei, ā, he tino rawaka mō te whakatika i ngā wero whakaemulsification e pā ana ki roto i tā mātou umanga.
