Whakaehunga - he ranunga wai

Whakaehunga - he ranunga o matū. Kei a ia ko matūriki rewa i roto i te tahi atu kotahi wāhanga pai. huaina ana tēnei whakauru ko "wāhanga dispersed". Ko tētahi atu taonga - purara reo. I roto i tona wae tuatahi tohaina te. "Whakaehunga" - tenei wā kua he takenga Latin. Whakamaoritia tikanga reira "ki te miraka, te waiu te". E hi'opoa tatou i tenei ariā i roto i te taipitopito atu.

Overview

No te mea i tetahi wai e rua e kore e e uru ranei huru matū, he reira taea ki te hanga i te whakaehunga. Ko tētahi o nga wae he wai tata tonu. Kei tētahi atu taonga o te rāpoi ngota ngonge neke kūpapa ranei (hei tauira ngako). Ko te mohiotia ki whakaehunga katoa tuatahi - he waiu. Here, dispersible te matūriki ngako i roto i te wai. Te rahi o te matūriki iti rawa o te wā marara ko 1-50 .mu.m, na e Ruiruia rare marara pūnaha. wai iti-kukū - hanganga. Ranunga ki te kukū tiketike - hanganga. I whenua thermodynamic hinu whakaehunga - ko te pūnaha iu. He nui ngā āhuatanga i roto i rūrūtia wāhanga, ka he hanganga te ranunga.

whakarōpū

Momo whakaehunga whiwhi tei runga i te ōwehenga wāhanga rōrahi me ratou hanganga, te nui me te āhua o te emulsifier, tona mahi matū, te tikanga, me te ranu tikanga.

1. hawhekaihe Direct ki matūriki iti o te wai apolar me rewakore i roto i te wāhanga neke (o / w - te faaiteraa "hinu i roto i te te wai"). Hoki taua ranunga o emulsifiers kia whakamahia ai e te hunga wairewa i te wai, pērā i matūriki o uku. E adsorbed ratou rāpoi i runga i te kiriata mata o te m-wāhanga, whakaiti mānukanuka kore anake, engari te hanga ano hoki i te kiriata mārō.
2. Kōaro (V / m) ranunga, e whakamahia nei mō te emulsifier wai-rewa.

pānga matū i runga i te whakaehunga, te pēhanga, huringa hanganga kia arahi ki koaro.

1. Freeze whakaehunga - he ranunga i hanga e te noa noa. Kei te whakaaro te reira ki te kia thermodynamically pūmau. E arohaehae tauira rare pūmau ka te rohe pāmahana mō te whakakotahi ngā wāhanga. Tenei kāwai hoki ngā lubricants me fluids mō te meangiti.
2. Lyophobic whakaehunga - he ranunga i hanga e aunoa, acoustic Pērā hiko ranei. He tino iu thermodynamically ratou. Taua ranunga kahore emulsifiers mo te wa roa e kore e te tīariari. wāhanga pai tae atu: surfactants, taimaha rāpoi tiketike, wai matū wairewa ki te totoka purara tiketike.

fariiraa

He hangarau production rua whakaehunga. Ko te tuatahi - te ara pai kuru wehenga. Ko te tuarua - te tukanga kiriata-hanga, aru i te whaturama ki nga wahi iti. I roto i te whakatinanatanga tuatahi, āta tāpiri te taonga kei te ki te purara. E mea titauhia e te ohorere, ko tonu i te faaururaa tere tiketike. I roto i tenei take, ka whakawhirinaki i runga i ngā āhuatanga i te kounga o te ranunga. I roto i ngā, i runga i te auau te ranu o whakahaere me te nui o te taonga dispersible, tona kukū, te pāmahana, me te kawatanga. Ko te tikanga tuarua - he tukanga i roto i nei i hanga i te kiriata i runga i te mata o tētahi atu wāhanga. Raro rangi puhia. Mirumiru kiriata roimata ki pata iti a whakaohokia te rōrahi katoa o te wai. I roto i to tatou wa i timata ki te whakamahi i te hau i muri o te ultrasound. Tenei ai kuru o te kiriata ki mongamonga noa iti.

ranunga whakangaromanga

Mai i reira he he pakaru māhorahora o te whakaehunga i runga i te wā. He wā i te mea e tika ana ki te whakatere i te tukanga, me te whakaiti i te kukū o te pūhui. Ko te hāngai tenei hiahia ina faataupupû i te aroaro o te whakaehunga tino takiwa te tukanga o te maimoatanga o te rauemi tona whakamahinga tika ranei. Ki te whakatere i te tukanga o te whakaiti i te kukū o te otinga i roto i te maha o ngā huarahi:

1. Ko te tikanga matū. tauhohenga whakamahia hoko kiriata mata o te emulsifier. I roto i tenei take whāpāharehia te tiaki tōraro o te tutonu i runga i te mata i te kiriata te. I runga i te parau tumu taua, te whakamahi o tāpiritanga organic hāngai tāpiringa kai (matū kaha biologically - demulsifiers).
2. Addition o te emulsifier meinga te hanganga o tīhiko, e kukume tōraro tiaki mata me te mata kiriata meinga emulsifier destabilizing. heke pūmautanga kāwanatanga otinga.
3. Whakauru o te tahi atu wähanga emulsifier surfactant (PAVom). i āna reira te kukū o te tuatahi, engari e kore ano e hanga i te kiriata feunga kaha.
4. tikanga Thermal. Ki tenei tikanga, i raro i te whakaehunga te ki pānga waiariki, e ai tona paihere.
5. tikanga aunoa. Kei te karanga a hoki tenei tikanga ahua he whakawehe. āta patia te whakaehunga i ki te hurihuri ki te nui tere koki ipu. hinga te otinga ki hautau wāhanga, he mea pauna.
6. Tikanga puranga hiko tāpiri kawehiko ki te whakaehunga ranei. I roto i tenei ara whakapōrearea ähuareka kino ranunga tiaki mata kiriata.

tono

Ko te whānuitanga o te tono o ngā rare i roto i te ahumahi nui. I roto i ngā, kei te whakamahia te pūhui:

1. I roto i te hanga o te mātiarīni me te pata.
2. I roto i te mahi hopi.
3. I roto i te hanga o ngā rauemi i hanga o rapa tūturu.
4. I roto i te hanga. Hei tauira, uku whakaehunga - he nonflammable tenei pūhui.
5. I roto i te ahuwhenua: patukīrea - he momo o te raau taero e whakangaro whakato pests.
6. Hoki ngā take hauora: izgotolvenie rerekē rongoā, hinu, poke.
7. I roto i te peita, te whakamahi i ngā peita whakaehunga.
8. Hair Poke, whakaehunga, tiaki te mata makawe, ka peita. Hei tauira, whakaehunga whakaahua (tenei oxidizer mō peita).
9. Te ahumahi hinu whakamahi i te ranunga o te wai ki te hinu, te manene o wāhanga wai tetahi ki tetahi e ai wahi ki rūrūtia iti - globules.
