Emulsion - imvura musanganiswa

Emulsion - musanganiswa zvinhu. Inoitwa chimwe chazvo choupfu nezvimedu insoluble mune dzimwe. chirungiso uyu anonzi "vakaparadzirwa kutotanga". Imwe fuma - kupararira svikiro. In wokutanga zvinoriumba yake anoparadzirwa. "Emulsion" - ichi izwi kwakatangira Latin. Ashandurwa kunoreva "mukaka, mukaka wacho". Ngationgororei pfungwa iyi zvizere.

tsananguro

Nekuti chero maviri mvura iyo hazvipindiri kana sei mishonga, zvinokwanisika kuti ive emulsion. Mumwe zvinoriumba ndiyo inenge nguva mvura. Chimwe fuma rine zvakaneta polar kana kwazvakarerekera mamorekuru (semuenzaniso kwemafuta). Wokutanga aizivikanwa emulsion zvose - zviri mukaka. Pano, namafuta nezvimedu dispersible mumvura. Kukura duku tudonhwe vakapararira danho iri 1-50 .mu.m, saka emulsions vari coarsely vakapararira hurongwa. Low-wevasungwa mvura - unstructured. Mixtures rurefu yevasungwa - muronga. On thermodynamic chikonzero mafuta emulsion - ane kusagadzikana hurongwa. Dimensions kuyaruka mumate makuru, uye musanganiswa riri unstructured.

kupatsanura

Type emulsion vakawana kunobva Pasika vhoriyamu ratios vavo sezvamunoita, mari uye yezvakaita emulsifier, ayo namakemikari basa, nzira nokusanganisira nzira.

1. Direct admixture pamwe duku nezvimedu ane apolar emura uye insoluble mune polar chokutambudzika (O / W - mashoko okuti "mafuta nemvura"). For wemisanganiswa dzakadaro emulsifiers angashandiswa zviri soluble nemvura, dzakadai tudonhwe nebhitumini. mamorekuru dzavo vari adsorbed panyika firimu kuti mamita-danho, achidzikisa kwete chete makakatanwa, asi kutanga yakasimba firimu.
2. Ivan Kuchin (V / m) nezvakavhenganiswa, iro rinoshandiswa mvura-insoluble emulsifier.

Chemical migumisiro pamusoro emulsion, kufurirwa, akafanana shanduko kungatungamirira inversion.

1. Emulsion Ndinoda - musanganiswa inopfurwa nomuzvarirwo nomuzvarirwo. Zvinonzi kuonekwa thermodynamically kugadzikana. Miyenzaniso achitsoropodza kugadzikana emulsions apo tembiricha muganhu kuti ndokusanganisa maitikiro. chikamu ichi zvinosanganisira lubricants uye zvinwiwa kuti kutonhora.
2. Lyophobic emulsion - musanganiswa inoumbwa zvemaziso, acoustic kana zvemagetsi kubatane nekuita. Ndivo thermodynamically aiminama. wemisanganiswa kwakadaro pasina emulsifiers kwenguva refu havapo. Good zvinoriumba kusanganisira: surfactants, yakakwirira samolecular uremu, mvura soluble zvinhu rurefu nezvishoma akapararira.

mutambo

Pane vaviri kugadzirwa michina emulsion. Chokutanga - nzira yakanaka unorema mapoka. Wechipiri - firimu-kusikwa muitiro, zvichiteverwa atsamwira zvidimbu zvidiki. In wokutanga musimboti, nefuma iri awedzera zvishoma nezvishoma kuti kupararira. Zvakafanira kuti takeover iri nguva kumhanya chaizvo inokurudzira. Panyaya iyi, kunaka musanganiswa kuchaenderana siyana zvinhu pamusoro. Zvikurukuru pamusoro kuvhenganisa mwero chourongwa uye mari dispersible fuma, ayo wevasungwa, tembiricha uye acidity. nzira yechipiri - mumwe mutoo umo firimu achiumbwa pasi pemvura mumwe Pasika. Bottom nomukondombera mhepo. Matema misodzi firimu kupinda madonhwe diki uye mwoyo wose vhoriyamu emura. Munguva yedu vakatanga kushandisa mhepo pachinzvimbo Ultrasound. Izvi zvinokonzera Kupwanya firimu kupinda kunyange chiduku zvidimbu.

kuparadzwa wemisanganiswa

Sezvo pane kwatangwa pakumedura emulsion pamusoro nguva. Pane mikana kana zvakakodzera kuwedzera kwacho uye kuderedza wevasungwa pakati mukomboni. Ichi chinodiwa rinoshanda apo kuvapo zvikuru kuramba emulsion kunokutadzisa muitiro kurapa emashoko kana ayo kushandiswa kwakarurama. Kuti mhanyisa muitiro kuderedza wevasungwa chemhinduro munzira dzakawanda:

1. Makemikari nzira. Used reagents ichikuvadza pose mafirimu ose emulsifier. Panyaya iyi akaipa nebasa vonyanya pemvura firimu iri neutralized. On the ichocho, kushandisa makemikari yokuvirisa yakavakirwa Mishonga zvokuwedzera (Biology vanoshingaira zvinhu - demulsifiers).
2. Kuwedzera imwe emulsifier kukonzera paumbwe cations, izvo zvinokwezva akaipa pamusoro mutariri uye pamusoro mafirimu vanokonzera kuzungunutsa emulsifier. mhinduro wehurumende Kugadzikana kunoderedza.
3. Kuzvitsinhanisa zvimwe zvinoriumba emulsifier surfactant (PAVom). It dilutes wevasungwa rokutanga, asi pacharo haritauri kuumba zvakakwana simba firimu.
4. Thermal nzira. With nzira iyi, iyo emulsion iri pasi chafariz zvinokonzerwa, izvo chinoita masumbu kwayo.
5. Zvokuimba nzira. Izvi musimboti nzira anonziwo separator. The emulsion akanga jekiseni zvishoma nezvishoma kunyika kutenderera huru chisina kutsetseka velocity mugaba. A mhinduro anyura chinoumba zvikamu zviduku kurema.
6. Nzira dzemagetsi ukapisa murwi kana kuwedzera electrolyte kuti emulsion. Nenzira iyi kuvhiringidza kudzikamiswa kunaka mutariri pamusoro wemisanganiswa firimu.

kunyoresa

Kuwanda kushanda emulsions vari indasitiri zvikuru. Kunyanya, yeimwe anoshandiswa:

1. In kugadzirwa margarine namafuta.
2. In sipo zvokuita.
3. In kugadzirwa nezvinhu zvakaitwa rwokuzvarwa rabha.
4. In kuvakwa. Somuenzaniso, bhitumini emulsion - remubatanidzwa iri nonflammable.
5. In zvokurima: mishonga yezvipembenene - siyana zvinodhaka kuti kuparadza chirimwa zvipukanana.
6. Kwezvokurapa zvinangwa: izgotolvenie zvakasiyana mishonga, mafuta okuzora, zvizorwa.
7. In kupenda, vachishandisa siyana emulsion pendi.
8. Hair okuzora, emulsion, inodzivirirawo bvudzi pamusoro apo kupenda. Somuenzaniso, emulsion vachiratidza (oxidizer iyi pendi).
9. The peturu indasitiri anoshandisa musanganiswa mvura nemafuta, sezvamakaropafadzwa kupararira mumwe mvura danho kune mumwe zvinoitika pamwe tuduku mumate - globules.
