Mabda'a iyo codsiga demulsifiers

Sababo la xiriira milmi-yaraanta adkaha qaarkood ee biyaha, marka mid ama dhowr ka mid ah adkahaasi ay ku jiraan tiro badan oo ah xal aqueous ah oo ay kacsadaan xoogaga biyaha ama kuwa dibadda, waxay ku jiri karaan xaalad ah emulsification biyaha gudahooda, samaynta emulsion. Aragti ahaan, nidaamkan oo kale waa mid aan degganayn. Si kastaba ha ahaatee, joogitaanka surfactants (sida qaybaha ciidda), emulsification ayaa noqda mid daran, taas oo ka dhigaysa xitaa adag in labada weji ay kala tagaan. Tan waxaa inta badan lagu arkaa isku dhafka biyaha saliidda inta lagu jiro kala-soocidda saliidda-biyaha iyo isku-dhafka biyaha-saliida ee daaweynta biyaha wasakhda ah, halkaas oo qaab-dhismeedka biyaha-saliid-ku-jira ama saliid-ku-jira ee biyaha u dhexeeya labada weji ay xasilloon yihiin. Aasaaska aragtiyeed ee dhacdadani waa "qaab-dhismeedka laba-lakab."

Xaaladahan oo kale, walxaha kiimikada qaarkood ayaa la soo bandhigaa si ay u carqaladeeyaan qaabdhismeedka laba-lakabka ah ee deggan oo ay dejiyaan nidaamka emulsified, si ay u gaaraan kala-soocidda labada weji. Wakiiladan, oo loo isticmaalo si gaar ah si loo jebiyo emulsions, waxaa loo yaqaan 'demulsifiers'.

Demulsifier-ku waa walax korka-firfircoon oo carqaladaysa qaab-dhismeedka dareeraha emulsified, oo kala saaraya wejiyada kala duwan ee emulsion-ka. Nadiifinta saliida ceyriin Waxa loola jeedaa habka loo isticmaalo fal-kicinta kiimikada si loo kala saaro saliidda iyo biyaha iyo isku dhafka saliidda-biyo-biyoodka, gaarista fuuq-baxa saliidda cayriin si loo buuxiyo heerarka nuxurka biyaha ee gaadiidka.

Hab wax ku ool ah oo toos ah oo lagu kala saaro wejiyada organic iyo aqueous waa isticmaalka demulsifiers si loo baabi'iyo emulsification oo ay carqaladeeyaan samaynta interface emulsification ku filan oo xoog leh, sidaas darteed gaaritaanka kala-soocidda wajiga. Si kastaba ha ahaatee, demulsifiers kala duwan ayaa ku kala duwan awoodda ay u leeyihiin inay baabi'iyaan wejiyada organic, iyo waxqabadkoodu si toos ah u saameeya waxtarka kala soocida wajiga.

Soo saarista penicillin, tillaabada muhiimka ah waxaa ka mid ah in penicillin laga soo saaro maraq halsano iyadoo la isticmaalayo dareere organic ah (sida butyl acetate). Sababtoo ah joogitaanka walxaha adag ee maraq halsano-sida borotiinka, sonkorta, iyo mycelia-isdhexgalka u dhexeeya wejiyada organic iyo aqueous ayaa noqda mid aan caddayn, samaynta gobol ee emulsification dhexdhexaad ah, kaas oo si weyn u saameeya dhalidda alaabta kama dambaysta ah. Si taas wax looga qabto, demulsifiers waa in la shaqeeyaa si loo jebiyo emulsion-ka, meesha looga saaro xaaladda ku-meel-gaadhka ah, oo loo gaaro kala-soocid degdeg ah oo waxtar leh.
