Emulsification iyo solubilization of surfactants
Surfactants waa fasal ballaaran oo isku-dhisyo dabiici ah oo leh sifooyin gaar ah, aad u dabacsan oo si ballaaran loo adeegsan karo, iyo qiimo wax ku ool ah oo weyn. Surfactants ayaa loo isticmaalay sida emulsifiers, saabuun, wakiilada qoynta, wakiilada galinta, wakiilada xumbo, dareeraha, kala firdhiya, wakiilada hakinta, biyo yareeya sibidhka, jilciyaasha, wakiilada siman, hagaajinta, jeermis dilayaasha, kicinta, biyaha celinaya, wakiilada wasakhda lidka ah, wakiilada boodhka, wakiilada boodhka wakiilada, dhumucyada, wakiilada xuubka, wakiilada sabbaynaya, wakiilada siman, wakiilada barakaca saliidda, wakiilada caking anti, carfiyo, wakiilada anti-static, wax ka beddelka dusha iyo daraasiin reagents kale functional nolol maalmeedka iyo beero badan oo warshadaha iyo beeraha wax soo saarka. Waxa intaa dheer in si weyn loo isticmaalo saabuunta iyo warshadaha la isku qurxiyo, surfactants ayaa sidoo kale loo isticmaalaa sida adjuvants ama lagu daro in warshadaha dhaqanka sida cuntada, caanaha, waraaqaha, maqaar, galaas, batroolka, fiilooyinka kiimikada, dunta, daabacaadda iyo rinjiyeynta, rinjiyeynta, farmashiyaha, sunta cayayaanka, nadiifinta, qalabka biraha, samaynta biraha, biraha, samaynta biraha cusub, samaynta biraha, samaynta biraha. sidoo kale beeraha farsamada sare. In kasta oo aanay inta badan ahayn tiir-dhexaadka wax-soo-saarka warshadaha, haddana waxa ay door muhiim ah ka ciyaari karaan in ay ku daraan dhammaystirka wax-soo-saarka badeecadaha kala duwan. In kasta oo isticmaalkeedu aanu weynayn, waxa ay door muhiim ah ka ciyaari kartaa kordhinta kala duwanaanta badeecada, yaraynta isticmaalka, badbaadinta tamarta, iyo horumarinta tayada.
Isbeddelka kobaca joogtada ah ee surfactants adduunka oo dhan wuxuu bixiyaa jawi dibadeed oo wanaagsan oo loogu talagalay horumarinta iyo koritaanka warshadaha qurxinta, iyo shuruudaha qaab dhismeedka badeecada, kala duwanaanta, waxqabadka, iyo tignoolajiyada ayaa sidoo kale sii kordhaya. Sidaa darteed, waxaa lagama maarmaan ah in si nidaamsan loo horumariyo surfactants kuwaas oo badbaado leh, khafiif ah, si fudud biodegradable, oo leh saameyn gaar ah, bixinta aasaaska aragtida horumarinta iyo codsiga alaabta cusub. Waa inaan diirada saarno horumarinta glycoside surfactants, oo ay ku jiraan polyols kala duwan iyo surfactants aalkolada; Cilmi-baaris nidaamsan iyo horumarinta surfactants fosfolipid soybean; Samee taxane ah aashitada khalka dufanka leh ee sukrose, xooji cilmi baarista isku dhafka tignoolajiyada, oo balaadhiso baaxadda codsiga ee alaabta jirta.
Ififaalaha ah in si isku mid ah u ekaysiiyo walxaha aan biyaha ku milmin biyaha si ay u sameeyaan emulsion waxaa loo yaqaan emulsification. Emulsifiers waxaa inta badan loo isticmaalaa soo saarista kiriimyada iyo lotion ee waxyaalaha la isku qurxiyo. Kareemka barafka ku salaysan budada caadiga ah iyo kareemka barafka ee Zhongxing labaduba waa O/W emulsions, kuwaas oo lagu dayan karo saabuun (saabuun). Way sahlan tahay in la soo saaro emulsion leh saliid yar iyadoo lagu dayo saabuun, saabuunta saabuuntuna waxay ka dhigi kartaa mid aad u sarreeya. Kareemada qabow oo ay ku jiraan xaddi badan oo saliid ah, emulsions waxay u badan yihiin nooca W/O, iyo emulsions lanolin dabiici ah oo leh nuugista biyaha sare iyo viscosity ayaa loo dooran karaa emulsification. Kuwa ugu badan ee hadda la isticmaalo waa emulsifiers-ka aan-ionic ahayn, sababtoo ah ammaankooda iyo xanaaqooda hooseeya.
Ifafaalaha kordhinta milanka ee walxaha wax yar milmaya ama aan la milmi karin waxaa loo yaqaan 'solubilization'. Marka surfactants lagu daro biyaha, xiisadda dusha sare ee biyuhu waxay bilaabaan inay si aad ah u yareeyaan, taasoo keenta samaynta miceles halkaas oo molecules surfactant ay isu geeyaan. Isku-duubnaanta walxaha loo isticmaalo in lagu sameeyo micelles waxaa loo yaqaan feejignaanta micelle ee muhiimka ah. Marka fiirsashada surfactants ay gaarto diirada micelle ee muhiimka ah, micelles waxay ku dhejin karaan saliid ama qaybo adag hal dhamaadka kooxda lipophilic, taas oo kordhinaysa milanka walxaha micro milmaya ama aan la milmi karin.
Ku darida dareeraha ee walxaha la isku qurxiyo waxaa inta badan loo isticmaalaa soo saarista toner, saliidaha timaha, iyo korriinka timaha iyo wakiilada nafaqeynta. Qaybaha saliidda leh ee walxaha la isku qurxiyo, sida udgoonka, saliidda, iyo fiitamiinnada saliidda lagu milmo, waxay leeyihiin qaabab milmayn oo kala duwan sababtoo ah kala duwanaanshahooda qaabdhismeed iyo dabaysha. Sidaa darteed, surfactants ku habboon waa in loo doortaa sida solubilizers. Haddii walxaha milmaya ee toner ay yihiin udgoon, saliid, iyo dawooyin, alkyl polyoxyethylene ether ayaa loo isticmaali karaa milanka.
Inkasta oo alkylphenol polyoxyethylene ethers (OP iyo TX) ay leeyihiin awood xoog leh, waxay ka xanaajiyaan indhaha guud ahaanna lama isticmaalo. Intaa waxaa dheer, walxaha amphoteric ee saliidda ku salaysan waxay leeyihiin milmayn heer sare ah oo saliidda basbaaska ah iyo saliidda khudradda, iyo kuwan surfactants maaha kuwo aan xanaaqin indhaha, iyaga oo ka dhigaya kuwo ku habboon diyaarinta waxyaabaha la isku qurxiyo ee aan xanaaqin sida shaambo.
