Sida loo doorto walxaha surfactants-ka ee loogu talagalay ka faa'iidaysiga saliidda culus iyo saliidda cayriin ee wax ku jirta

1. Surfactants-ka soo saarista saliidda culus

Sababtoo ah daxalka sare iyo dareeraha liita ee saliidda culus, ka faa'iidaysigeeda waxaa la kulmaa dhibaatooyin badan. Si loo soo celiyo saliidda culus ee noocaas ah, xalalka biyaha ee surfactants mararka qaarkood ayaa lagu duraa godka hoose. Habkani wuxuu saliidda culus ee viscosity-ga sare u beddelaa emulsions saliid-ku-jirta biyaha (O/W) oo leh daxal hoose, kaas oo markaa lagu shubi karo dusha sare. Surfactants-ka loo isticmaalo habkan daxalka saliidda culus iyo yaraynta daxalka waxaa ka mid ah sodium alkyl sulfonate, polyoxyethylene alkyl alcohol ether, polyoxyethylene alkyl phenol ether, polyoxyethylene polyoxypropylene polyene polyamine, iyo sodium polyoxyethylene alkyl alcohol ether sulfate.

Emulsions-ka saliidda ku jira biyaha ayaa loo baahan yahay in la fuuq-celiyo si loo kala saaro qaybta biyaha, taas oo sidoo kale u baahan in la isticmaalo surfactants-ka warshadaha qaarkood sida demulsifiers. Demulsifiers-yadan waa emulsifiers-ka biyaha ku jira (W/O), oo leh noocyo caadi ah oo ay ku jiraan cationic surfactants, naphthenic acids, asphatenic acids, iyo milixdooda birta ee polyvalent.

Noocyada gaarka ah ee saliidda culus ee aan laga faa'iideysan karin cutubyada bamgareynta caadiga ah, duritaanka uumiga ayaa loo baahan yahay si loo soo celiyo kulaylka. Si loo xoojiyo waxtarka soo kabashada kulaylka, waxaa loo baahan yahay surfactants. Duritaanka xumbo - tusaale ahaan, duritaanka walxaha xumbada u adkaysta heerkulka sare oo ay weheliso gaasaska aan la isku qasin karin - ceelasha duritaanka uumiga waa mid ka mid ah farsamooyinka caadiga ah ee la qaato. Wakiilada xumbaynta ee inta badan la isticmaalo waxaa ka mid ah alkylbenzene sulfonate, α-olefin sulfonate, petroleum sulfonate, sulfonated polyoxyethylene alkyl alcohol ether, iyo sulfonated polyoxyethylene alkyl phenol ether.

Marka la eego firfircoonidooda sare ee dusha sare iyo xasilloonida asiidhyada, alkalis, oksijiinta, kulaylka, iyo saliidda, surfactants-ka fluorinated waxaa loo arkaa inay yihiin wakiillo ku habboon xumbo heerkulka sare leh. Intaa waxaa dheer, si loo fududeeyo marinka saliidda kala firdhisan iyada oo loo marayo cunaha daloolada sameynta ama kor loogu qaado barokaca saliidda ee dusha sare ee sameynta, surfactants-ka loo yaqaan wakiilada faafinta filimka ayaa la isticmaalaa, iyadoo nooca caadiga ah ee la isticmaalo uu yahay polyoxyalkylated phenolic resin polymer surfactants.

2.Surfactants-ka loogu talagalay soo kabashada Saliidda Cayriin ee Waxy

Si loo soo celiyo saliidda cayriin ee wax-soo-saarka leh, hawlgallada ka hortagga wax-soo-saarka iyo ka saarista wax-soo-saarka waa in si joogto ah loo sameeyaa, halkaas oo surfactants ay u adeegaan sidii labadaba wax-soo-saareyaasha wax-soo-saarka iyo kuwa wax-soo-saarka.

Suffactants-ka ka hortagga shamaca waxay u kala baxaan laba qaybood: surfactants-ka ku milma saliidda iyo surfactants-ka ku milma biyaha. Kuwa hore waxay sameeyaan saameyntooda ka hortagga shamaca iyagoo wax ka beddelaya sifooyinka dusha sare ee kiristaalo shamaca, iyadoo sulfonates-ka batroolka iyo surfactants-ka nooca amine-ka ay yihiin noocyada caadiga ah ee la isticmaalo. Surfactants-ka ku milma biyaha waxay shaqeeyaan iyagoo beddelaya astaamaha dusha sare ee shamaca ku shuba (sida dusha sare ee tuubada saliidda, ulaha nuugista iyo qalabka la xiriira). Xulashooyinka la heli karo waxaa ka mid ah sodium alkyl sulfonates, cusbada ammonium quaternary, alkane polyoxyethylene ethers, aromatic hydrocarbon polyoxyethylene ethers, iyo sidoo kale soodhiyam sulfonate-kooda.

Surfactants-ka loogu talagalay ka saarista shamac ayaa sidoo kale loo qaybiyaa laba nooc iyadoo lagu saleynayo xaaladaha ay adeegsadaan. Surfactants-ka ku milma saliidda waxaa lagu daraa surfactants-ka ku salaysan saliidda, halka surfactants-ka ku milma biyaha - oo ay ku jiraan nooca sulfonate, nooca cusbada ammonium ee quaternary, nooca polyether, nooca Tween iyo nooca OP-ga, iyo sidoo kale nooca sulfate-esterified ama sulfonated Peregal-ka iyo nooca OP-ga - loo isticmaalo surfactants-ka ku salaysan biyaha.

Sannadihii ugu dambeeyay, warshadaha gudaha iyo kuwa caalamiga ahba waxay lahaayeen ka saarista shamaca si dabiici ah oo ay weheliso teknoolojiyada ka hortagga shamaca, iyo isku-darka ka saarista shamaca ku salaysan saliidda iyo biyaha si loo sameeyo ka saarista shamaca isku-dhafan. Badeecadaha noocaas ah waxay adeegsadaan hydrocarbons udgoon iyo hydrocarbons udgoon isku dhafan marxaladda saliidda, iyo emulsifiers oo leh sifooyin ka saarista shamaca marxaladda biyaha. Marka emulsifier-ka la doortay uu yahay surfactant aan ionic ahayn oo leh dhibic daruur ku habboon, heerkulka ka hooseeya qaybta dhigista shamaca ee ceelka saliidda wuxuu gaari karaa ama ka gudbi karaa barta daruurtiisa. Natiijo ahaan, ka saarista shamaca isku-dhafan wuxuu baabi'iyaa ka hor inta uusan gelin qaybta dhigista shamaca, isagoo u kala qaybinaya laba qaybood oo si wada jir ah u shaqeeya si looga saaro shamaca.
