1. Nga taputapu whakaehunga Ko nga taputapu miihini mo te whakarite i te emulsion ko te nuinga o te emulsifier, he momo taputapu emulsification e whakakotahi ana i te hinu me te wai. I tenei wa, e toru nga momo matua o te emulsifiers: te whakaranu emulsification, te mira colloid me te homogenizer. Ko te momo, te hanganga me te mahi o te emulsifier he hononga nui ki te rahi (dispersibility) o nga matūriki whakaehunga me te kounga (te pumau) o te emulsion. Ko te tikanga, penei i te emulsifier whakakorikori e whakamahia nuitia ana i roto i nga wheketere whakapaipai, he ngoikore te whakamararatanga o te emulsion kua rite. He nui, he taratara hoki nga matūriki, he iti ake te pumau, he kaha ake te poke. Heoi, he ngawari tana hanga, he iti noa te utu. I te mea ka kowhiria e koe he hanganga whaitake o te miihini me te whakamahi tika, ka taea hoki e ia te whakaputa whakapaipai rongonui me nga whakaritenga kounga hiato whanui. I nga tau tata nei, he nui te ahunga whakamua o te hoahoa Homogenizer Vacuum Mixer Homogenizer, a, ko te whakaehunga i mahia e te Homogenizer Homogenizer Homogenizer he tino pai te whakamararatanga me te pumau.
2. Te pāmahana He nui te awe o te pāmahana emulsification i runga i te kounga o te emulsification, engari kahore he rohe tino i runga i te pāmahana. Mena he wai te hinu me te wai, ka taea te whakaehunga ma te whakaoho i te pāmahana rūma. Ko te tikanga, ko te pāmahana whakaemulsification e whakawhirinaki ana ki te rewa o te matū rewa teitei kei roto i nga wahanga e rua, me te whakaaro ano hoki i nga mea penei i te momo whakaemulsifier me te whakarewatanga o te wahanga hinu me te wahanga wai. I tua atu, ko te pāmahana o nga waahanga e rua me noho tata tonu, ina koa mo nga waahanga wax me nga waahanga ngako me nga tohu whakarewa teitei ake (i runga ake i te 70°C), i te wa e whakaemihia ana, kaore e taea te taapiri i te waahanga wai mahana iti hei aukati i te wax, Ka miramira te ngako, ka puta he pupuhi, he taratara ranei, he whakaehunga koretake. Ko te tikanga, i te wa o te whakaehunga, ka taea te whakahaere i te mahana o nga wahanga hinu me te wai i waenga i te 75°C me te 85°C. Mena kei roto i te wahanga hinu he wax rewa teitei me etahi atu waahanga, ka nui ake te pāmahana whakaemulsification i tenei wa. I tua atu, ki te nui haere te pokey i roto i te tukanga whakaemulsification, te mea-ka karanga matotoru rawa, me te pa ki te whakaoho, ka taea te whakanui i te pāmahana whakaemulsification tika. Ki te te emulsifier whakamahia he etahi pāmahana kōaro wāhanga, te pāmahana whakaemulsification hoki pai tīpakohia huri noa i te pāmahana kōaro wāhanga. Ko te pāmahana emulsification hoki i etahi wa ka pa ki te rahi matūriki o te whakaehunga. Hei tauira, i te wa e whakamahia ana te waikawa fatty hopi anionic emulsifier mo te emulsification e te tikanga hopi tuatahi, i te wa e whakahaerehia ana te pāmahana emulsification i te 80 °C, ko te rahi o te matūriki o te emulsion e pa ana ki te 1.8-2.0 μm. Mena ka mahia te whakaehunga i te 60 °C, he 6 μm te rahi o te matūriki. A, no te whakaemulsifiers nonionic emulsifiers, te pānga o te pāmahana whakaemulsification i runga i te rahi matūriki he ngoikore.
3. Te wa whakaehunga oKorehau Whakaranu Homogenizerhoahoa Ko te wa whakaehunga he awe ki runga i te kounga o te whakaehunga, a ko te whakatau i te wa whakaehunga e ahu mai ana i runga i te owehenga rōrahi o te wahanga hinu me te wahanga wai, te pokey o nga wahanga e rua me te pokey o te whakaehunga ka puta. , te momo me te nui o te emulsifier, Kei reira ano te pāmahana emulsification, engari ko te wa emulsification ko te hanga i te punaha emulsified tino, e hono tata ana ki te pai o nga taputapu whakaehunga. Ko te wa whakaehunga ka taea te whakatau i runga i nga wheako me nga whakamatautau. Mena ka whakamahia he homogenizer (3000 rpm) mo te whakaehunga, he 3-10 meneti noa iho.
4. He nui te awe o nga taputapu Emulsification i runga i te emulsification, ko tetahi o enei ko te painga o te tere whakaoho i runga i te emulsification. He ngawari te tere whakakorikori kia tino uru te wahanga hinu me te wahanga wai, a he tiketike rawa te tere whakaoho.
5. Tere whakakorikori oKorehau Whakaranu Homogenizer He nui te awe o te hoahoa ki te whakaemulsification, ko tetahi ko te awe o te tere whakaoho i runga i te whakaemulsification. Ko te tere o te whakakorikori kia tino uru te wahanga hinu me te wahanga wai. Mena he iti rawa te tere whakakorikori, karekau e tutuki te kaupapa o te whakaranu katoa. Heoi, ki te nui rawa te tere o te whakakorikori, ka kawea mai nga mirumiru hau ki roto i te punaha, ka waiho hei punaha toru-waahanga. Ka whakarekereke i nga whakaehunga. Na reira, me karohia te urunga o te hau i te wa e whakaohooho ana, a he pai te mahi a te emulsifier korehau.
