Qaab-dhismeedka ether-ka dufanka leh ee polyglycerolwaxyaabaha surfactants-ka ahWaxaa lagu muujiyay sawirka hoose. Kooxahooda hydrophilic waxay sidoo kale ka kooban yihiin kooxo hydroxyl iyo xiriiro ether ah. Si kastaba ha ahaatee, isku-dubaridka beddelka ah ee kooxaha hydroxyl iyo xiriiro ether way ka duwan yihiin surfactants polyoxyethylene ether nonionic, kuwaas oo ay ku badan yihiin xiriiro ether ah. Ka dib marka lagu milmo biyaha, marka laga reebo sameynta xiriiro hydrogen ah oo daciif ah oo u dhexeeya atamka oksijiinta ee xiriiro ether iyo atamka hydrogen ee biyaha sida surfactants polyoxyethylene ether, waxay sidoo kale la falgeli karaan biyaha iyada oo loo marayo kooxaha hydroxyl. Sababtan awgeed, surfactants ether polyglycerol ee dufanka leh waxay gaari karaan milmi biyo oo wanaagsan iyagoo wata tiro yar oo ah durdugs glycidol, hydrophilicity-kooduna aad ayuu uga sarreeyaa kan surfactants polyoxyethylene ether.
Intaa waxaa dheer, surfactants-ka dufanka leh ee polyglycerol ether waxay leeyihiin qaab-dhismeedka amiinada dabiiciga ah, iyagoo siinaya sifooyin labada surfactants ee aan ionic iyo cationic ahayn. Marka tirada adducts-ku yar tahay, waxay muujiyaan astaamaha surfactants-ka cationic, sida iska caabbinta aashitada laakiin dulqaad la'aanta alkali iyo dhaqdhaqaaq gaar ah oo bakteeriyada dila. Marka tirada adducts-ku korodho, sifooyinkooda aan ionic ahayn ayaa sii muuqda. Kuma soo daadan doonaan xalalka alkaline-ka firfircoonidooduna waxay ahaan doontaa mid aan waxba tarayn. Iyadoo aan ionicity-ga la kordhinayo iyo cationicity-ga la daciifiyay, is-waafajintooda aan ionic ahayn ayaa la dhimayaa, taasoo u oggolaanaysa labada nooc ee surfactants in si isku dhafan loo isticmaalo.
Waxaa loo isticmaalay gudahawarshadaha dharka lagu dhaqo
Surfactants-ka dufanka leh ee polyglycerol ether waxay muujiyaan sifooyin kala duwan iyadoo ku xiran tirada durdurrada ay ku shubaan. Tirada durdurrada hooseeya waxay siisaa sifooyinka durdurrada cationic, iyagoo hagaajinaya milmidooda heerkulka hooseeya isla markaana keenaya saabuun aad u fiican heerkul ballaaran. Marka tirada durdurrada ay korodho, dabeecaddooda aan diirka lahayn ayaa sii muuqata. Kuma soo daadan doonaan xalalka alkaline-ka ah firfircoonidooda dusha sarena way sii ahaanaysaa mid sugan. Iyada oo la xoojiyay sifooyinka aan diirka lahayn iyo sifooyinka cationic-ga ee daciifka ah, isku darka durdurrada anionic waxay si weyn u yareyn kartaa xiisadda dusha sare waxayna hagaajin kartaa awoodaha emulsifying iyo qoynta. Sida saameynta hydrophilicity iyo steric ee silsiladaha polyoxyethylene, durdurradan ayaa sidoo kale si weyn u joojin kara roobka ama isku-darka saabuunta. Intaa waxaa dheer, duldurrada polyglycerol ee dufanka leh ee amine waxay leeyihiin sifooyin jilicsan oo ka hortag ah, kuwaas oo si wax ku ool ah u xallin kara dhibaatada dareenka gacanta ee xun ee alaabta fiber-ka ka dib marka la dhaqo.
Loo isticmaaloEmulsifiers-ka sunta cayayaanka
Marka laga soo tago waxqabadka wanaagsan ee emulsifying ee surfactants-ka aan ionic ahayn, surfactants-ka dufanka leh ee amine polyglycerol ether sidoo kale waxay leeyihiin sifooyin gaar ah oo bakteeriyada dila iyo jeermiska dila ee surfactants-ka cationic, taasoo ka dhigaysa surfactants-ka isku-dhafan ee badan. Waxay kordhin karaan wasakhda waxayna hagaajin karaan milmida heerkulka hooseeya, taas oo si weyn u xoojinaysa la qabsiga heerkulka ee microemulsions-ka sunta cayayaanka ee lagu sameeyay iyaga. Noocan surfactant-ka isku-dhafan, amine polyglycerol ether dufan leh, wuxuu leeyahay hufnaan sare oo ku saabsan sameynta microemulsions-ka O/W. Waxay ka caawisaa yareynta qiyaasta surfactants-ka waxayna yareysaa kharashyada wax soo saarka.
Diyaari wakiilka ka hortagga xasaasiyadda
Surfactants-ka dufanka leh ee amine polyglycerol ether waxay samayn karaan filim biyo ah oo joogto ah oo ku yaal dusha sare ee fiber-ka iyagoo adeegsanaya isku xidhka hydrogen ee u dhexeeya kooxahooda hydrophilic, kooxaha hydroxyl iyo molecules-ka biyaha, taasoo keenaysa nuugista qoyaanka iyo socodka qoyaanka oo aad u fiican. Dhanka kale, waxay samayn karaan filim saliid hydrophobic ah oo ku yaal dusha sare ee fiber-ka si loo yareeyo is-jiidjiidka fiber-ka iyo soo saarista korontada taagan, waxayna sidoo kale siiyaan fiilooyinka jilicsanaan iyo siman. Intaa waxaa dheer, qaybta hydrophobic ee surfactants-ka amine polyglycerol ether ee dufanka leh waxay la mid tahay tan surfactants-ka amine polyoxyethylene ether ee dufanka leh. Maadaama glycidol halkii ethylene oxide lagu daray qaybteeda hydrophilic, waxay leedahay hydrophilicity xooggan. Sidaas darteed, nuugista qoyaanka iyo waxqabadka gudbinta ayaa ka fiican surfactants-ka polyoxyethylene ether ee caadiga ah. Intaa waxaa dheer, surfactants-ka amine polyglycerol ether ee dufanka leh aad bay uga sun yar yihiin oo way ka xanaaq badan yihiin surfactants-ka cationic, taasoo ka dhigaysa inay ballanqaadaan wakiillo ka hortag ah oo waxqabad sare leh.
Diyaari khafiif ahalaabta daryeelka shakhsi ahaaneed
Diyaarinta walxaha dufanka leh ee polyglycerol ether ee ka soo baxa glycidol, qaab-dhismeedka walxaha dufanka leh ee polyglycerol ethers waxay ka kooban yihiin isku-xidhka ether iyo kooxaha hydroxyl halkii ay ka ahaan lahaayeen isku-xidhka ether. Tani waxay ka hortagtaa sameynta dioxane, taasoo ka dhigaysa walxahan surfactants kuwo ka ammaan badan walxaha polyoxyethylene ether-ka ah. Intaa waxaa dheer, walxaha dufanka leh ee polyglycerol ether ether waxay ka kooban yihiin tiro badan oo kooxo hydroxyl ah, kuwaas oo kor u qaada hydrophilicity, yareeya cuncunka oo keena saameyn fudud oo ku timaadda jirka aadanaha. Sidaa darteed, waxaa loo adeegsadaa in lagu sameeyo alaabada daryeelka shaqsiyeed ee fudud, gaar ahaan kuwa loogu talagalay dhallaanka iyo carruurta yaryar.
Codsiga daaweynta dusha sare ee midabka
Daraasaduhu waxay muujiyeen in surfactants-ka aan ionic ahayn ee nooca amine-ka dufanka leh ay keenaan natiijooyin aad u wanaagsan oo ku saabsan isbeddelka dusha sare ee midabada cagaaran ee phthalocyanine. Waxqabadka wanaagsan waxaa loo aaneynayaa sababaha soo socda: surfactants-ka noocaas ah waxaa lagu nuugi karaa dusha sare ee midabka iyadoo la samaynayo xiriir haydarojiin ah oo u dhexeeya atamka haydarojiin ee kooxaha hydroxyl (-OH) iyo kooxaha amino (-NH) iyo atamka nitrogen-ka ee dusha sare ee midabada cagaaran ee phthalocyanine. Silsiladaha hydrocarbon-kooda lipophilic ayaa markaa sameeya filim dahaar ah oo la nuugay. Dahaarkani wuxuu si wax ku ool ah uga hortagaa isku-darka walxaha midabka inta lagu jiro habka qalajinta wuxuuna joojiyaa koritaanka sii kordhaya ee miraha kristal-ka, ugu dambeyntiina wuxuu soo saaraa walxo midab leh oo leh kiristaalo fiican.
Marka midabada wax laga beddelay la dhigo warbaahinta dabiiciga ah, silsiladaha haydaro-biyoodka, kuwaas oo leh iswaafajin wanaagsan oo la leh warbaahinta dabiiciga ah, si dhakhso ah ayay u xalliyaan si ay u sameeyaan filim xalla'aan ah. Tani waxay sahlaysaa kala firdhinta walxaha midabka waxayna ka hortagtaa isku-soo-ururinta marka walxaha isku soo dhawaadaan. Saamayntan waxaa la xoojiyaa marka silsiladaha haydaro-biyoodku ay dheeraadaan filimka xalla'aanta ahna uu qaro weynaado, taas oo ka caawisa in la nadiifiyo walxaha midabka iyo in la gaaro qaybinta cabbirka walxaha cidhiidhiga ah. Kooxaha hydrophilic ee surfactants-ka waxay sameeyaan filim qoyaan leh ka dib fuuq-baxa, taas oo sidoo kale si wax ku ool ah u hor istaagta isku-soo-ururinta walxaha midabka waxayna hagaajisaa kala firdhistooda.
Surfactants-ka dufanka leh ee polyglycerol ether waxay leeyihiin hydrophilicity sare waxayna samayn karaan filimo qoyaan qaro weyn leh. Sidaas darteed, midabyada lagu daweeyay surfactants-kan si fudud ayay ugu faafmaan biyaha iyagoo leh cabbirro yar yar, taasoo muujinaysa rajo wanaagsan oo loo isticmaali karo daaweynta dusha sare ee midabada cagaaran ee phthalocyanine.
