1. Ko nga taputapu miihini 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.Ko nga matūriki he nui, he taratara, he iti ake te pumau, he kaha ake te poke.Heoi, he ngawari tana hanga, he iti 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 he pai te whakamararatanga me te pumau o te whakaehunga i mahia e te hoahoa Homogenizer Vacuum Mixer Homogenizer.
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 ki 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 viscosity 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 te hoki pai tīpakohia huri noa 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 hopi waikawa ngako emulsifier anionic mo te emulsification e te tikanga hopi tuatahi, ka whakahaeretia 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. Wā whakaemulsification oKorehau Whakaranu Homogenizerhoahoa Ko te wa whakaehunga e tino whai mana ana ki te kounga o te whakaehunga, a ko te whakatau i te wa whakaehunga 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 hoki te pāmahana emulsification, engari ko te wa emulsification ko te hanga i te punaha kia tino whakakoi, e hono tata ana ki te pai o nga taputapu emulsification.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 whakaemulsification, 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.
He maha nga tau o te mohio a Smart Zhitong i roto i te whanaketanga, te hoahoa Vacuum Mixer HomogenizerKorehau Whakaranu Homogenizerme te kaha o te miihini mai i te 5L ki te 18000L
