Isticmaalka walxaha dufanka leh ee polyglycerol ether surfactants

Qaab-dhismeedka ether-ka dufanka leh ee polyglycerolsunfactantWaxaa lagu muujiyey sawirka hoose. Kooxaheeda 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 waxay beddelaan qaab-dhismeedka ay ku badan yihiin xiriirka ether ee polyoxyethylene ether-nooca nonionic surfactants. Ka dib marka lagu milmo biyaha, marka laga reebo sameynta xiriiro hydrogen daciif ah oo u dhexeeya atamka oksijiinta ee ku jira xiriirka ether iyo atamka hydrogen ee biyaha sida kan dambe, waxay sidoo kale la falgeli kartaa biyaha iyada oo loo marayo kooxaha hydroxyl. Sidaa darteed, surfactants ether ee amine polyglycerol dufanka leh waxay gaari karaan milmi biyo oo wanaagsan iyadoo la adeegsanayo tiro yar oo lagu daray glycidol, taasoo la macno ah in surfactants ether ee dufanka leh ay leeyihiin hydrophilicity aad uga xoog badan surfactants nooca polyoxyethylene ether. Intaa waxaa dheer, surfactants ether ee dufanka leh ee polyglycerol dufanka leh waxay ka kooban yihiin qaab-dhismeedka amines organic, iyagoo siinaya sifooyin qayb ah oo ah surfactants nonionic iyo cationic labadaba. Marka tirada lagu daro ay hooseyso, waxay muujiyaan astaamaha surfactants cationic, sida iska caabbinta aashitada laakiin iska caabbinta alkali oo liidata iyo dhaqdhaqaaq bakteeriya oo gaar ah. Marka tirada lagu daro ay korodho, dabeecadooda nonionic waa la kordhiyaa; Ma soo daadan doonaan xalalka alkaline-ka ah, firfircoonidooduna dusha sare way sii ahaanaysaa mid sugan. Marka sifooyinka aan ionic ahayn ay kordhaan oo sifooyinka cationic-ga ay hoos u dhacaan, is-waafajintooda surfactants-ka anionic-ka ayaa daciifta, taasoo suurtogalinaysa in labada noocba si isku dhafan loo isticmaalo.

Waayo,dhaqidda warshadaha

Surfactants-ka dufanka leh ee polyglycerol ether waxay muujiyaan sifooyin kala duwan iyadoo ku xiran tirada durdurrada kala duwan. Tirada durdurrada oo hooseysa waxay siisaa durdurrada astaamaha durdurrada cationic, waxay hagaajisaa milmideeda heerkulka hoose, waxayna bixisaa saabuun aad u fiican heerkul ballaaran. Marka tirada durdurrada ay korodho, dabeecadda aan ionic ahayn way korodhaa, sidaa darteed durdurradu ma soo degi doonto xalalka alkaline-ka ah dhaqdhaqaaqeeda dusha sarena way sii ahaanaysaa mid sugan. Maadaama sifooyinka aan ionic ahayn ay xoogaystaan ​​​​oo sifooyinka cationic-ga ay daciifaan, isku darka durdurrada anionic waxay si weyn u yareyn kartaa xiisadda dusha sare waxayna kor u qaadi kartaa waxqabadka emulsifying iyo qoynta. Sida silsiladaha polyoxyethylene, hydrophilicity-keeda iyo saameynta caqabadda steric-ga waxay si weyn u xakameyn kartaa roobka ama isku-darka saabuunta. Intaa waxaa dheer, durdurrada polyglycerol ee amine dufanku waxay leeyihiin sifooyin jilicsan oo ka hortag ah, kuwaas oo ka gudbi kara dhibaatada dareenka gacanta oo liita ka dib marka la dhaqo alaabta fiber-ka.

Loo isticmaaloEmulsifiers-ka sunta cayayaanka

Maadaama subagga amine polyglycerol ether surfactants ay leeyihiin sifada emulsifying ee subfactants-ka aan ionic ahayn iyo saameyn gaar ah oo bakteeriyada dila iyo jeermiska dila ee surfactants-ka cationic, waxay u adeegaan sidii surfactant isku dhafan oo "badan-shaqo leh". Ma aha oo kaliya inay kor u qaadi karaan wasakhda laakiin sidoo kale waxay hagaajin karaan milmida heerkulka hooseeya, taasoo si weyn u xoojinaysa la qabsiga heerkulka ee microemulsions-ka sunta cayayaanka ee lagu sameeyay iyaga. Surfactant-kan isku dhafan wuxuu muujiyaa hufnaan sare oo ku saabsan sameynta microemulsions-ka O/W, kaas oo ka caawiya yaraynta qiyaasta surfactant-ka iyo dhimista kharashyada.

DiyaarintaWakiilada Ka-hortagga Aan Joogtada Ahayn

Surfactants-ka dufanka leh ee polyglycerol ether waxay samayn karaan filim biyo ah oo joogto ah oo ku yaal dusha sare ee fiber-ka iyada oo loo marayo isku xidhka hydrogen ee u dhexeeya kooxaha hydrophilic, kooxaha hydroxyl iyo molecules-ka biyaha, taasoo keenaysa nuugista qoyaanka wanaagsan iyo socodka korontada. Dhanka kale, waxay samayn karaan filim saliid hydrophobic ah oo ku yaal dusha sare ee fiber-ka si loo yareeyo is-xoqidda fiber-ka loona yareeyo soo saarista korontada taagan, iyo sidoo kale inay bixiyaan jilicsanaan iyo simanaan. Intaa waxaa dheer, qaybta hydrophobic ee surfactants-ka dufanka leh ee polyglycerol ether-ka waxay la mid tahay tan surfactants-ka dufanka leh ee polyoxyethylene ethers. Si kastaba ha ahaatee, glycidol halkii laga isticmaali lahaa ethylene oxide ayaa lagu daraa qaybta hydrophilic, taasoo keenta hydrophilicity xooggan. Sidaas darteed, nuugista qoyaanka iyo waxqabadka gudbiyaha ayaa ka sarreeya surfactants-ka caadiga ah ee polyoxyethylene ether. Intaa waxaa dheer, surfactants-ka dufanka leh ee polyglycerol ether-ka dufanka leh ayaa aad uga sun yar oo ka xanaajin badan surfactants-ka cationic-ka, taasoo ka dhigaysa musharixiinta rajo-gelinta leh ee ah wakiillo ka hortagga waxqabadka sare leh.

DiyaarintaBadeecadaha Daryeelka Shakhsi ahaaneed ee Fudud

Inta lagu jiro isku-darka surfactants-ka dufanka leh ee polyglycerol ether ee amine iyadoo la adeegsanayo glycidol, qaab-dhismeedka molecular-ka wuxuu muujiyaa isku-xidhka ether-ka ee beddelka ah iyo kooxaha hydroxyl halkii laga isticmaali lahaa isku-xidhka ether-ka ee ugu badan. Tani waxay ka hortagtaa sameynta dioxane waxayna keentaa badbaado sare marka la barbar dhigo surfactants-ka polyoxyethylene ether. Intaa waxaa dheer, kooxaha hydroxyl ee badan ee ku jira surfactants-ka dufanka leh ee polyglycerol ether-ka waxay hagaajiyaan hydrophilicity waxayna yareeyaan cuncunka, taasoo keenta khafiifnimo weyn maqaarka aadanaha. Sidaa darteed, surfactants-ka dufanka leh ee polyglycerol ether-ka ayaa lagu dabaqi karaa sameynta alaabada daryeelka shaqsiyeed ee fudud, gaar ahaan alaabada daryeelka shaqsiyeed ee carruurta.

Codsiga Wax ka beddelka Dusha Sare ee Midabka

Xu Yanli'Cilmi-baaristu waxay muujinaysaa in walxaha aan ahayn kuwa ku salaysan dufanka ee amine-ka ay natiijooyin wanaagsan ka gaaraan daaweynta dusha sare ee midabada cagaaran ee phthalocyanine. Waxqabadka la rabo wuxuu ka yimaadaa habka soo socda: walxaha noocaas ah waxaa lagu nuugi karaa dusha sare ee midabka iyada oo loo marayo isku xidhka haydarojiin ee u dhexeeya atamka haydarojiin ee kooxaha -OH iyo -NH iyo atamka nitrogen ee dusha sare ee midabka cagaaran ee phthalocyanine. Silsiladaha hydrocarbon-ka ee lipophilic waxay dhisaan filim dahaar ah oo la nuugay. Dahaarka la sameeyay wuxuu si wax ku ool ah uga hortagaa isku-darka walxaha midabka inta lagu jiro qalajinta wuxuuna joojiyaa koritaanka kiristaalka dheeraadka ah, isagoo soo saaraya walxo midab oo si fiican u dhalaalaya. Marka midabada la daweeyay lagu meeleeyo warbaahinta dabiiciga ah, silsiladaha hydrocarbon waxay muujiyaan iswaafajin wanaagsan oo leh warbaahinta dabiiciga ah waxayna si dhakhso ah u milmaan si ay u sameeyaan filim xal ah, taasoo sahlaysa kala firdhinta midabka. Dhanka kale, filimku wuxuu carqaladeeyaa isku-darka marka walxaha midabku ay isku soo dhawaadaan. Saamayntani waxay ku sii xoogaysanaysaa silsiladaha hydrocarbon-ka ee dheer iyo filimada xalalka qaro weyn, iyagoo doorbidaya sifaynta walxaha midabka iyo qaybinta cabbirka walxaha cidhiidhiga ah. Kooxaha hydrophilic-ga waxay nuugaan si ay u soo saaraan filimada fuuq-celinta, kuwaas oo si wax ku ool ah u xakameynaya isku-dhafka walxaha midabka oo fududeynaya kala firdhinta. Surfactants-ka dufanka leh ee polyglycerol ether waxay leeyihiin hydrophilicity sare waxayna samayn karaan filimaan fuuq-celin oo dhumuc weyn leh. Sidaas darteed, midabyada lagu daweeyay subagga amine polyglycerol ether surfactants waxay si fudud ugu faaftaan biyaha iyagoo leh cabbirro yar yar, taasoo muujinaysa rajo wanaagsan oo loo adeegsado daawaynta dusha sare ee midabada cagaaran ee phthalocyanine.
