Ulwakhiwo lwe-fatty amine polyglycerol etheri-surfactantkuboniswe kumfanekiso ongezantsi. Amaqela ayo athanda amanzi akhiwe ngamaqela e-hydroxyl kunye neebhondi ze-ether. Nangona kunjalo, ukulungelelaniswa kwamaqela e-hydroxyl kunye neebhondi ze-ether kutshintsha isakhiwo esilawulwa yi-ether se-polyoxyethylene ether-type nonionic surfactants. Emva kokunyibilika emanzini, ngaphandle kokwenza iibhondi ze-hydrogen ezibuthathaka phakathi kwee-athomu ze-oxygen kwiibhondi ze-ether kunye nee-athomu ze-hydrogen emanzini afana nala alandelayo, inokunxibelelana namanzi ngamaqela e-hydroxyl. Ke ngoko, ii-fatty amine polyglycerol ether surfactants zinokufumana ukunyibilika kwamanzi okuhle ngenani elincinci lokongeza i-glycidol, oko kuthetha ukuba ii-fatty amine polyglycerol ether surfactants zinamandla kakhulu e-hydrophilicity kunee-polyoxyethylene ether-type surfactants. Ukongeza, ii-fatty amine polyglycerol ether surfactants ziqulathe ulwakhiwo lwee-organic amines, ezinika iipropati ezingengako zee-nonionic kunye nee-cationic surfactants. Xa inani lokongeza liphantsi, zibonisa iimpawu zee-cationic surfactants, ezifana nokuxhathisa i-asidi kodwa ukuxhathisa okuphantsi kwe-alkali kunye nomsebenzi othile wokubulala iintsholongwane. Xa inani lokongeza linyuka, uphawu lwazo olungelulo lwe-ionic luyanda; aziyi kungena kwizisombululo ze-alkaline kwaye umsebenzi wazo womphezulu uhlala unjalo. Njengoko iipropati ezingezizo ze-ionic zisanda kwaye iipropati ze-cationic ziyancipha, ukungahambelani kwazo nee-surfactants ze-anionic kuyabuthathaka, nto leyo evumela ukuba ezi ntlobo zimbini zisetyenziswe ngokudibeneyo.
Ngokubaukuhlamba impahla kwimizi-mveliso
Ii-surfactants ze-Fatty amine polyglycerol ether zibonisa iimpawu ezahlukeneyo ngokuxhomekeke kumanani ahlukeneyo e-adduct. Inani eliphantsi le-adduct linika i-surfactant iimpawu ze-cationic surfactants, liphucula ukunyibilika kwayo kumaqondo obushushu aphantsi, kwaye linikezela nge-detergent entle kakhulu kumanqanaba obushushu abanzi. Xa inani le-adduct linyuka, uphawu lwe-nonionic luyanda, ngoko i-surfactant ayizukungena kwizisombululo ze-alkaline kwaye umsebenzi wayo womphezulu uhlala unjalo. Njengoko iimpawu ze-nonionic ziqina kwaye iimpawu ze-cationic zibuthathaka, ukuyixuba ne-anionic surfactants kunokunciphisa kakhulu uxinzelelo lomphezulu kwaye kunyuse ukusebenza kwe-emulsifying kunye nokumanzisa. Njengee-polyoxyethylene chains, i-hydrophilicity yayo kunye ne-steric impact effect inokuthintela kakhulu imvula okanye ukuhlangana kweesepha. Ngaphezu koko, i-fatty amine polyglycerol ether ineempawu ezithile zokuthambisa kunye ne-antistatic, ezinokoyisa ingxaki yokungaziva kakuhle kwesandla emva kokuhlamba iimveliso zefayibha.
Isetyenziselwaizihlanganisi zezinambuzane
Njengoko ii-surfactants ze-fatty amine polyglycerol ether zineempawu ezintle zokuxubha ii-surfactants ezingezizo ii-ionic kunye neziphumo ezithile zokubulala iintsholongwane kunye nokubulala iintsholongwane ze-cationic surfactants, zisebenza njenge-surfactant exutyiweyo "enemisebenzi emininzi". Azinakuphakamisa kuphela ukudumba kodwa zikwaphucula ukunyibilika kumaqondo obushushu aphantsi, ziphucula kakhulu ukuguquguquka kobushushu bee-microemulsions zezinambuzane ezenziwe ngazo. Le surfactant yohlobo oluxutyiweyo ibonisa ukusebenza kakuhle ekwenzeni ii-microemulsions ze-O/W, ezinceda ukunciphisa idosi ye-surfactant kunye nokunciphisa iindleko.
Ukulungiswa kweIiarhente zokungashukumi
Ii-surfactants ze-ether ze-fatty amine polyglycerol zinokwenza ifilimu yamanzi eqhubekayo kwiindawo zefayibha ngokusebenzisa iibhondi ze-hydrogen phakathi kwamaqela e-hydrophilic, amaqela e-hydroxyl kunye neemolekyuli zamanzi, ngaloo ndlela zibonelela ngokufunxwa komswakama okuhle kunye nokuqhuba kombane. Okwangoku, zinokwenza ifilimu yeoyile ye-hydrophobic kwiindawo zefayibha ukunciphisa ukungqubana kwefayibha kunye nokunciphisa ukuveliswa kombane ozinzileyo, kwaye zinike ukuthamba kunye nokuthamba. Ukongeza, icandelo le-hydrophobic le-surfactants ze-ether ze-fatty amine polyglycerol lifana nele-ethers ze-fatty amine polyoxyethylene. Nangona kunjalo, i-glycidol endaweni ye-ethylene oxide yongezwa kwicandelo le-hydrophilic, nto leyo ebangela ukufunxwa komswakama okunamandla. 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 ebenza babe ngabagqatswa abathembisayo njengee-antistatic agents ezisebenza kakuhle.
Ukulungiswa kweIimveliso zoNyango loBuqu eziPhantsi
Ngexesha lokwenziwa kwe-fatty amine polyglycerol ether surfactants kusetyenziswa i-glycidol, ulwakhiwo lwe-molecular lune-ether bonds ezitshintshanayo kunye namaqela e-hydroxyl endaweni ye-ether bonds ikakhulu. Oku kuthintela ukwakheka kwe-dioxane kwaye kunika ukhuseleko oluphezulu xa kuthelekiswa ne-polyoxyethylene ether surfactants. Ngaphezu koko, amaqela amaninzi e-hydroxyl kwi-fatty amine polyglycerol ether surfactants aphucula i-hydrophilicity kwaye anciphise ukucaphuka, nto leyo ebangela ubuthathaka obukhulu kulusu lomntu. Ke ngoko, i-fatty amine polyglycerol ether surfactants iyasebenza ekwenzeni iimveliso zokhathalelo lomntu oluncinci, ngakumbi iimveliso zokhathalelo lomntu losana.
Isicelo kwiPigment Surface Modification
Xu Yanli'Uphando lutyhila ukuba ii-surfactants ezinamafutha asekelwe kwi-amine ezisekelwe kwi-amine zifumana iziphumo ezilungileyo kunyango lomphezulu wee-pigment eziluhlaza ze-phthalocyanine. Ukusebenza okunqwenelekayo kuvela kule ndlela ilandelayo: ezi surfactants zinokufunxwa kwiindawo ze-pigment ngokusebenzisa i-hydrogen bonding eyenziwe phakathi kwee-athomu ze-hydrogen kumaqela e--OH kunye ne-NH kunye nee-athomu ze-nitrogen kwiindawo ze-pigment eziluhlaza ze-phthalocyanine. Ii-hydrocarbon chains zazo ze-lipophilic zakha ifilimu yokugquma efunxwayo. I-coating eyenziweyo ithintela ngokufanelekileyo ukuhlangana kwee-pigment particles ngexesha lokomisa kwaye ithintela ukukhula kwekristale okungakumbi, ivelise ii-pigment pigment ezi-crystalline kakuhle. Xa ii-pigment eziphathweyo zibekwe kwi-organic media, ii-hydrocarbon chains zihambelana kakuhle ne-organic media kwaye zinyibilika ngokukhawuleza ukwenza ifilimu yokunyibilika, ziququzelela ukusasazeka kwe-pigment. Okwangoku, ifilimu iyathintela ukuqubha xa ii-pigment particles zisondelana. Esi siphumo siqina nge-hydrocarbon chains ezinde kunye nee-twist solvation films ezityebileyo, zikhuthaza ukucocwa kwee-pigment particles kunye nokusasazwa kobukhulu bee-particles ezincinci. Amaqela e-hydrophilic hydrate ukuvelisa ii-hydration films, ezithintela ngempumelelo ukuqubha phakathi kwee-pigment particles kwaye ziququzelele ukusasazeka. Ii-surfactants ze-ether ezinamafutha zinobumanzi obuphezulu kwaye zinokwenza iifilimu zokufunxa amanzi ezityebileyo. Ngokunjalo, ii-pigments eziphathwe ngee-surfactants ze-ether ezinamafutha zisasazeka lula emanzini aneenxalenye ezincinci, nto leyo ebonisa amathuba athembisayo okusetyenziswa konyango lomphezulu wee-pthalocyanine green pigments.
