Emulsion - isku dar ah dareere

Emulsion - isku dar ah ee walxaha. Waxay ka kooban tahay mid ka mid ah qayb Qurub ganaax beelaya in kale ah. qayb Tan waxa loo yaqaan "marxaladda kala firdhiyey". walax kale - dhexdhexaad ah kala firidhsan. In iyada qayb koowaad waxaa la qaybiyey. "Emulsion" - xilli uu leeyahay asalka ah Latin. Turjumay waxa ay ka dhigan tahay "caanaha, caanaha". Ina keena aynu baaro fikirka this si faahfaahsan.

Guudmarka

Sababtoo ah laba dareere kasta oo hana ku khaldina ama kiimikaad fal, waxaa suurtagal ah si ay u sameeyaan emulsion ah. Mid ka mid ah qaybaha ugu had iyo jeer waa biyo. walax kale oo ka kooban taagoo ah imaanshada iyo horjeeda ama dhexdhexaad ah (tus dufanka). Kii u horreeyey ayaa lagu yaqaan in emulsion oo dhan - waa caano. Halkan, Qurub baruurtii milma biyo. size ee Qurub ugu yar ee wajiga kala firdhay waa 1-50 .mu.m, sidaas emulsions waxaa coarsely kala firdhiyey nidaamka. Low-fiirsashada dareere - qaabaysnayn. ANAAD la uruuray sare - habaysan. On dhulka thermodynamic emulsion saliid - waa hab aan degganayn. Cabirka in dhibco wajiga waa kuwo waaweyn, oo isku dar ah waa qaabaysnayn.

kala soocidda

emulsion Nooca helaa waxay ku xiran tahay saamiga mugga wajiga iyo halabuurka, cadadka iyo nooca emulsifier ah, waxqabad kiimikada ay, habka iyo dariiqada isku qasin.

1. shaydi Direct la qayb yar oo dareere ah apolar iyo beelaya in wajiga kala horjeeda (o / w - muujinta "saliid biyo"). Waayo, isku sida ee ✰Saliidda qubeyska waxaa loo isticmaali karaa oo waa L. biyo, sida Qurub of dhoobo. taagoo waxaa lagu adsorbed on film dusha of m-wajiga, yaraynta xiisadda ma aha oo kaliya, laakiin sidoo kale la abuuro film adag.
2. -Bedelka (V / m) isku dar ah, kaas oo waxaa loo isticmaalaa emulsifier biyo-beelaya.

saamaynta Chemical on emulsion, cadaadis, isbedelka ka kooban keeni karta in inversion.

1. Emulsion xanibay - isku dar ah in la aasaasay degna degna. Waxaa la arkaa in ay thermodynamically deggan. Tusaale ahaan adag tahay emulsions deggan marka xadka heerkulka for qasayso weji ah. category Tani waxay sidoo kale waxaa ka mid ah saliidaha iyo dheecaannada for qaboojinta.
2. Lyophobic emulsion - isku dar ah la sameeyey by si farsamaysan, loomana baahno ama qasayso korontada. Waxay thermodynamically waa mid aad u kacsan. isku noocan oo kale ah iyada oo aan ✰Saliidda qubeyska muddo dheer aan ka jirin. qaybaha Good oo ay ku jiraan: surfactants, miisaanka sare kelli, biyo walxaha milma la a kala firidhsan adkaha sare.

soo dhaweynta

Waxaa jira laba teknoolajiyada saarka emulsion. Midkii kowaad wuxuu u - habka ugu wanaagsan burburiyo kooxaha. habka film-sameynta, raaceen by dillaac burburi - labaad. In muuqashadii ugu horeysay, walaxda si tartiib ah ku daray in ay kala firidhsan. Waxaa lagama maarmaan ah in la wareegidda si joogto ah waa at qaboobo xawaaraha sare ah. Xaaladdan oo kale, tayada isku dar ah ku xirnaan doonaa waxyaabo kala duwan. Gaar ahaan, on heerka isku qasin maamulka iyo lacagta oo ah walaxda milma, ay fiirsashada, heerkulka iyo ashitada. Habka labaad - geeddi-socodka ah, taas oo filim laga sameeyey oo korka ka mid ah wajiga kale. hawada hoose Suurka. Goobooyin film jeex galay dhibco yar oo kiciyey mugga oo dhan ee dareeraha ah. In waqtigeena waxay bilaabeen inay isticmaalaan hawada halkii ultrasound. Tani waxay keentaa in burburiyo filimka burburi xitaa kuwa yaryar.

isku baabba '

Tan iyo markii ay jirto breaking ah oo lama filaan ah ee emulsion ah muddo. Waxaa jira jeer marka waxaa lagama maarmaan ah in la dardar-socodka iyo in la yareeyo fiirsashada ee xarunta. baahida loo qabo Tani waa ku haboon marka joogitaanka emulsion aad u xoog caqabad habka daaweynta ee wax ama isticmaalkeeda saxda ah. Si aad u dardar-socodka ah ee yaraynta fiirsashada of xal siyaabo dhowr ah:

1. Habka kiimikada. reagents isticmaalay dhaawac filimada dusha of emulsifier ah. Xaaladdan oo kale amarka xun ee xoogga dushiisa film la Kipury. On mabda'a isku mid ah, isticmaalka daro organic ku salaysan supplements cuntada (walxaha bayoloji firfircoon - demulsifiers).
2. Intaa waxaa dheer ee emulsifier ah ku keeni formation of siifilisku, kaas oo soo jiidan lacag dusha iyo dusha filimada xun keeni emulsifier amni darro. xal xasiloonida gobolka hoos.
3. Bedelay of qayb kale surfactant emulsifier (PAVom). Waxaa dilutes fiirsashada ee ugu horeysay, laakiin aanu u sameeyaan filim ku filan oo xoog leh.
4. Habka kaamerada. Iyadoo habkan, emulsion waxaa la hoos geliyey wax saamayn kaamerada, kaas oo keena in ay xidhmo.
5. hab farsamaysan. Habka muuqashadii waxaa kaloo loo yaqaan SEPARATOR ah. emulsion ayaa waxaa si tartiib tartiib ah mudaa ku qoqobada la weyn angular xawaare weelka. Xalka burburo galay jajab qayb miisaan.
6. Habka dhex tuulnaa korontada ama elektrolytka ku daray in emulsion ah. Sidaas carqaladeeyo xasilin isku dusha lacag negative film.

codsiga

kala duwan ee codsiga of emulsions in industry aad u. Gaar ahaan, xeryahooda ee waxaa loo isticmaalaa:

1. In wax soo saarka ee margarine iyo subagga.
2. In saabuun qaadashada.
3. In wax soo saarka ee qalabka of caag dabiiciga ah sameeyey.
4. In dhismaha. Tusaale ahaan, emulsion shinida - xarunta tani waa ku safrayaan.
5. In beeraha, sunta cayayaanka - noocyo kala duwan oo daroogo in baabbi'in cayayaanka dhirta.
6. Ujeedooyinka caafimaadka: izgotolvenie daawooyinka kala duwan, cadar, isku qurxiyo.
7. In rinjiyeynta, iyadoo la isticmaalayo rinjiga emulsion kala duwan.
8. Timaha Cosmetics, emulsion, ilaaliya dusha timaha markii rinjiyaynta. Tusaale ahaan, soo bandhigista emulsion (oxidizer this for rinjiga).
9. The warshadaha petroleum isticmaalaa isku dar ah oo biyo ah oo saliid uu ku jiray kala firidhsan ka mid ah wajiga dareere kale ku qaadataa meel la dhibco yar - globules.
