Ulwakhiwo lwe-fatty amine polyglycerol etherizinto ezibangela ukudumbakuboniswe kumfanekiso ongezantsi. Amaqela abo athanda amanzi aqulunqwe ngamaqela e-hydroxyl kunye neebhondi ze-ether. Nangona kunjalo, ulungelelwaniso olutshintshanayo lwamaqela e-hydroxyl kunye neebhondi ze-ether lwahlukile kwii-surfactants ze-polyoxyethylene ether nonionic, ezilawulwa ziibhondi ze-ether. Emva kokunyibilika emanzini, ngaphandle kokwenza iibhondi ze-hydrogen ezibuthathaka phakathi kwee-athomu ze-oxygen zeebhondi ze-ether kunye nee-athomu ze-hydrogen emanzini afana nee-surfactants ze-polyoxyethylene ether, zinokusebenzisana namanzi ngamaqela e-hydroxyl. Ngenxa yesi sizathu, ii-surfactants ze-fatty amine polyglycerol ether zinokufezekisa ukunyibilika kwamanzi okuhle ngenani elincinci le-glycidol adducts, kwaye i-hydrophilicity yazo iphezulu kakhulu kuneye-surfactants ze-polyoxyethylene ether.
Ukongeza, ii-fatty amine polyglycerol ether surfactants zibonisa ulwakhiwo lwee-organic amines, zinika iipropati zee-nonionic kunye nee-cationic surfactants. Xa inani le-adducts liphantsi, zibonisa iimpawu zee-cationic surfactants, ezifana nokumelana ne-asidi kodwa ukunganyamezelani ne-alkali kunye nomsebenzi othile wokubulala iintsholongwane. Xa inani le-adducts lisanda, iipropati zazo ze-nonionic ziba zibonakala ngakumbi. Aziyi kukhawuleza kwizisombululo ze-alkaline kwaye umsebenzi wazo womphezulu uhlala ungaguquki. Ngokuphucuka kwe-nonionicity kunye ne-cationionicity ebuthathaka, ukungahambelani kwazo nee-anionic surfactants kuyancitshiswa, okuvumela ukuba iintlobo ezimbini ze-surfactants zisetyenziswe ngokudibeneyo.
Isetyenziswa kwiimboni yokuhlamba impahla
Ii-surfactants ze-Fatty amine polyglycerol ether zibonisa iimpawu ezahlukeneyo ngokuxhomekeke kumanani azo e-adduct. Inani eliphantsi le-adduct lizinika iimpawu ze-cationic surfactants, ziphucula ukunyibilika kwazo kumaqondo obushushu aphantsi kwaye zinikezele nge-detergents entle kakhulu kumanqanaba obushushu abanzi. Xa inani le-adduct linyuka, uphawu lwazo lwe-nonionic luba lubonakala ngakumbi. Aziyi kungena kwizisombululo ze-alkaline kwaye umsebenzi wazo womphezulu uhlala unjalo. Ngeempawu ze-nonionic eziphuculweyo kunye neempawu ze-cationic ezibuthathaka, ukuzixuba ne-anionic surfactants kunokunciphisa kakhulu uxinzelelo lomphezulu kwaye kuphucule amandla e-emulsifying kunye nokumanzisa. Ngokufana ne-hydrophilicity kunye ne-steric impact ye-polyoxyethylene chains, ezi surfactants zinokuthintela kakhulu ukuna okanye ukuhlangana kweesepha. Ukongeza, ii-fatty amine polyglycerol ethers zineempawu zokuthambisa kunye ne-antistatic, ezinokusombulula ngempumelelo ingxaki yokuziva kakubi kwezandla zeemveliso zefayibha emva kokuhlamba.
Isetyenziselwaizihlanganisi zezinambuzane
Ngaphandle kokusebenza kakuhle kokuxubha ii-surfactants ezingezizo ii-ionic, ii-surfactants ze-fatty amine polyglycerol ether zikwanazo neempawu ezithile zokubulala iintsholongwane kunye nokubulala iintsholongwane kwii-surfactants ze-cationic, nto leyo ezenza zibe zii-surfactants ezidityanisiweyo ezinemisebenzi emininzi. Zinokunyusa ukudumba kwaye ziphucule ukunyibilika kumaqondo obushushu aphantsi, nto leyo ephucula kakhulu ukuguquguquka kobushushu bee-microemulsions zezinambuzane ezenziwe ngazo. Olu hlobo lwe-composite surfactant, i-fatty amine polyglycerol ether, lusebenza kakuhle kakhulu ekwenzeni ii-microemulsions ze-O/W. Inceda ukunciphisa umthamo wee-surfactants kwaye inciphise iindleko zemveliso.
Lungisa i-arhente yokulwa nokuguquguquka
Ii-surfactants ze-ether ze-Fatty Amine Polyglycerol zinokwenza ifilimu yamanzi eqhubekayo kumphezulu wefayibha ngokusebenzisa iibhondi ze-hydrogen phakathi kwamaqela azo athanda amanzi, amaqela e-hydroxyl kunye neemolekyuli zamanzi, ngaloo ndlela zibonelela ngokufunxwa komswakama kunye nokuqhuba kakuhle. Okwangoku, zinokwenza ifilimu yeoyile ethanda amanzi kumphezulu wefayibha ukunciphisa ukungqubana kwefayibha kunye nokuveliswa kombane ongashukumiyo, kwaye zinike neefayibha ubuthambile kunye nokuthamba. Ukongeza, icandelo le-hydrophobic le-surfactants ze-ether ze-fatty amine polyglycerol lifana nele-ether ye-fatty amine polyoxyethylene. Ekubeni i-glycidol endaweni ye-ethylene oxide yongezwa kwicandelo layo le-hydrophilic, ine-hydrophilicity enamandla. Ngenxa yoko, ukufunxwa komswakama kunye nokusebenza kwayo okuqhubayo kudlula ii-surfactants ze-ether ze-polyoxyethylene eziqhelekileyo. Ngaphezu koko, ii-surfactants ze-ether ze-fatty amine polyglycerol azinabungozi kwaye azicaphukisi kangako kune-surfactants ze-cationic, nto leyo eyenza ukuba zibe zii-antistatic agents ezithembisayo eziphezulu.
Lungisa kancinciiimveliso zokhathalelo lomntu
Ekulungiseleleni ii-surfactants ze-fatty amine polyglycerol ether ezivela kwi-glycidol, ulwakhiwo lwee-fatty amine polyglycerol ethers lune-ether bonds ezitshintshanayo kunye namaqela e-hydroxyl endaweni yokuba zilawulwe zii-ether bonds. Oku kuthintela ukwakheka kwe-dioxane, okwenza ezi surfactants zikhuseleke kune-polyoxyethylene ether-type surfactants. Ukongeza, ii-fatty amine polyglycerol ether surfactants ziqulathe inani elikhulu lamaqela e-hydroxyl, aphucula i-hydrophilicity, anciphise ukucaphuka kwaye anike iziphumo ezithambileyo emzimbeni womntu. Ke ngoko, zisetyenziswa ukwenza iimveliso zokhathalelo lomntu ezithambileyo, ngakumbi ezo zeentsana nabantwana abancinci.
Isicelo kunyango lomphezulu we-pigment
Izifundo zibonise ukuba ii-surfactants ezingezizo ii-ionic zohlobo lwe-amine ezinamafutha zizisa iziphumo ezibalaseleyo ekuguqulweni komphezulu wee-pigment eziluhlaza ze-phthalocyanine. Ukusebenza okuhle kubangelwa zezi zizathu zilandelayo: ezi surfactants zinokufunxwa kumphezulu we-pigment ngokwenza ii-hydrogen bonds phakathi kwee-athomu ze-hydrogen kumaqela e-hydroxyl (-OH) kunye namaqela e-amino (-NH) kunye nee-athomu ze-nitrogen kumphezulu wee-pigment eziluhlaza ze-phthalocyanine. Ii-lipophilic hydrocarbon chains zazo emva koko zenze ifilimu yokugquma efunxwayo. Olu gquma luthintela ngokufanelekileyo ukuhlangana kwee-pigment particles ngexesha lenkqubo yokomisa kwaye luthintele ukukhula ngakumbi kwee-crystal grain, ekugqibeleni luvelise ii-pigment particles ezineekristale ezintle.
Xa imibala eguquliweyo ibekwe kwi-organic media, imixokelelwane ye-hydrocarbon, ehambelana kakuhle ne-organic media, ikhawuleza inyibilike ukuze yenze ifilimu enyibilikisiweyo. Oku kwenza kube lula ukusasazeka kwamasuntswana e-pigment kwaye kuthintele ukuqunjelwa xa amasuntswana esondelana. Esi siphumo siyanda njengoko imixokelelwane ye-hydrocarbon ikhula kwaye ifilimu enyibilikisiweyo iqina, nto leyo enceda ekucoceni amasuntswana e-pigment kwaye ifezekise ukusasazwa kobukhulu besuntswana obuncinci. Amaqela e-hydrophilic e-surfactants enza ifilimu equnyiweyo emva kokuqunjelwa, nto leyo ekwathintela ukuqunjelwa phakathi kwamasuntswana e-pigment kwaye iphucule ukusasazeka kwawo.
Ii-surfactants ze-ether ze-Fatty Amine Polyglycerol zinobumanzi obuphezulu kwaye zinokwenza iifilimu ezimanzi kakhulu. Ngoko ke, ii-pigments eziphathwe ngezi surfactants zisasazeka lula emanzini aneenxalenye ezincinci, nto leyo ebonisa amathuba okusetyenziswa kwazo kunyango lomphezulu we-phthalocyanine green pigments.
