Isakhiwo se-fatty amine polyglycerol etherama-surfactantkuboniswe esithombeni esingezansi. Amaqembu abo athanda amanzi nawo akhiwe amaqembu e-hydroxyl kanye nama-ether bond. Kodwa-ke, ukuhlelwa okushintshanayo kwamaqembu e-hydroxyl kanye nama-ether bond kuhlukile kuma-surfactants e-polyoxyethylene ether nonionic, alawulwa ama-ether bond. Ngemva kokuncibilika emanzini, ngaphandle kokwakha ama-hydrogen bond abuthakathaka phakathi kwama-athomu e-oxygen ama-ether bond kanye nama-athomu e-hydrogen emanzini njenge-polyoxyethylene ether surfactants, angasebenzisana namanzi ngamaqembu e-hydroxyl. Ngenxa yalesi sizathu, ama-surfactants e-fatty amine polyglycerol ether angafinyelela ukuncibilika okuhle kwamanzi ngenani elincane lama-glycidol adducts, futhi i-hydrophilicity yawo iphakeme kakhulu kuneyama-surfactants e-polyoxyethylene ether.
Ngaphezu kwalokho, ama-fatty amine polyglycerol ether surfactants anesakhiwo sama-organic amine, ewanika izakhiwo zama-nonionic kanye nama-cationic surfactants. Uma inani lama-adducts liphansi, abonisa izici zama-cationic surfactants, njengokumelana ne-asidi kodwa ukungabekezelelani kwama-alkali kanye nomsebenzi othile wokubulala amagciwane. Uma inani lama-adducts landa, izakhiwo zawo ze-nonionic ziba zivelele kakhulu. Ngeke zifinyelele ezixazululweni ze-alkaline futhi umsebenzi wazo wobuso uhlala unjalo. Ngokuthuthuka kwe-nonionicity kanye ne-cationionicity ebuthakathaka, ukungahambelani kwazo nama-anionic surfactants kuyancishiswa, okuvumela izinhlobo ezimbili zama-surfactants ukuthi zisetshenziswe ndawonye.
Kusetshenziswe ku-imboni yokuwasha
Ama-surfactants e-Fatty amine polyglycerol ether abonisa izakhiwo ezahlukene kuye ngezinombolo zawo ze-adduct. Inombolo ephansi ye-adduct iwanikeza izici zama-surfactants e-cationic, ithuthukisa ukuncibilika kwawo emazingeni okushisa aphansi futhi ilethe ukuhlanza okuhle kakhulu ebangeni lokushisa elibanzi. Lapho inombolo ye-adduct ikhuphuka, uhlamvu lwawo lwe-nonionic luba luvelele kakhulu. Ngeke angene ezixazululweni ze-alkaline futhi umsebenzi wawo wobuso uhlala unjalo. Ngezakhiwo ezithuthukisiwe ze-nonionic kanye nezakhiwo ze-cationic ezibuthakathaka, ukuzihlanganisa nama-surfactants e-anionic kunganciphisa kakhulu ukungezwani kobuso futhi kuthuthukise amakhono e-emulsifying kanye nokumanzisa. Ngokufana nomphumela we-hydrophilicity kanye nomphumela we-steric wokuvinjelwa kwamaketanga e-polyoxyethylene, lawa ma-surfactants angavimbela kakhulu ukuna noma ukuhlangana kwezinsipho. Ngaphezu kwalokho, ama-ether e-fatty amine polyglycerol anezakhiwo zokuthambisa kanye ne-antistatic, ezingaxazulula ngempumelelo inkinga yokuzizwa kabi kwesandla kwemikhiqizo ye-fiber ngemva kokuwasha.
Kusetshenziselwaama-emulsifier ezibulala-zinambuzane
Ngaphandle kokusebenza okuhle kakhulu kokumulisa ama-surfactants angewona ama-ionic, ama-surfactants e-fatty amine polyglycerol ether nawo anezakhiwo ezithile zokubulala amagciwane kanye nokubulala amagciwane zama-surfactants e-cationic, okwenza abe ama-surfactants ahlanganisiwe anemisebenzi eminingi. Angandisa ukuthambisa futhi athuthukise ukuncibilika emazingeni okushisa aphansi, okuthuthukisa kakhulu ukuzivumelanisa nokushisa kwama-microemulsions ezibulala izinambuzane akhiwe ngawo. Lolu hlobo lwe-composite surfactant, i-fatty amine polyglycerol ether, lusebenza kahle kakhulu ekwakheni ama-microemulsions e-O/W. Lusiza ukunciphisa umthamo wama-surfactants futhi lunciphise izindleko zokukhiqiza.
Lungisa i-antistatic agent
Ama-surfactants e-fatty amine polyglycerol ether angakha ifilimu yamanzi eqhubekayo ebusweni be-fiber ngezibopho ze-hydrogen phakathi kwamaqembu awo athanda amanzi, amaqembu e-hydroxyl nama-molecule amanzi, ngaleyo ndlela alethe ukumuncwa komswakama okuhle kakhulu kanye nokuqhuba kahle. Okwamanje, angakha ifilimu kawoyela ethanda amanzi ebusweni be-fiber ukunciphisa ukungqubuzana kwe-fiber kanye nokukhiqizwa kukagesi ozinzile, futhi anikeze imicu ubumnene kanye nokushelela. Ngaphezu kwalokho, ingxenye ye-hydrophobic yama-surfactants e-fatty amine polyglycerol ether ifana neye-fatty amine polyoxyethylene ether. Njengoba i-glycidol esikhundleni se-ethylene oxide ingezwa engxenyeni yayo ethanda amanzi, ifaka i-hydrophilicity enamandla. Ngakho-ke, ukumuncwa komswakama kanye nokusebenza kwayo okuqhubayo kudlula ama-surfactants e-polyoxyethylene ether avamile. Ngaphezu kwalokho, ama-surfactants e-fatty amine polyglycerol ether awanobuthi futhi awacasuli kakhulu kune-cationic surfactants, okwenza abe ama-antistatic agents athembisayo asebenza kahle kakhulu.
Lungisa kancaneimikhiqizo yokunakekela umuntu siqu
Ekulungiseleleni ama-surfactants e-fatty amine polyglycerol ether avela ku-glycidol, isakhiwo sama-ethers e-fatty amine polyglycerol sinezibopho ze-ether ezishintshanayo namaqembu e-hydroxyl esikhundleni sokubuswa yizibopho ze-ether. Lokhu kuvimbela ukwakheka kwe-dioxane, okwenza la ma-surfactants aphephe kakhulu kune-surfactants yohlobo lwe-polyoxyethylene ether. Ngaphezu kwalokho, ama-surfactants e-fatty amine polyglycerol ether aqukethe inani elikhulu lamaqembu e-hydroxyl, athuthukisa i-hydrophilicity, anciphise ukucasuka futhi alethe imiphumela emnene emzimbeni womuntu. Ngakho-ke, asetshenziswa ekwakheni imikhiqizo yokunakekelwa komuntu siqu emnene, ikakhulukazi leyo yezinsana nezingane ezincane.
Isicelo ekwelapheni ubuso be-pigment
Izifundo zibonise ukuthi ama-surfactant angewona ama-ionic ohlobo lwe-amine anamafutha aletha imiphumela emihle kakhulu ekuguqulweni kobuso be-pigment eluhlaza ye-phthalocyanine. Ukusebenza okuhle kubangelwa yizizathu ezilandelayo: ama-surfactant anjalo angafakwa ebusweni be-pigment ngokwakha izibopho ze-hydrogen phakathi kwama-athomu e-hydrogen emaqenjini e-hydroxyl (-OH) kanye nama-amino group (-NH) kanye nama-athomu e-nitrogen ebusweni be-pthalocyanine green pigments. Amaketanga awo e-hydrocarbon e-lipophilic abese enza ifilimu yokumboza efakwe i-adsorbed. Lokhu kuhlanganiswa kuvimbela ngempumelelo ukuhlangana kwezinhlayiya ze-pigment ngesikhathi senqubo yokomisa futhi kuvimbele ukukhula okwengeziwe kwezinhlamvu zekristalu, ekugcineni kuveze izinhlayiya ze-pigment ngamakristalu amahle.
Uma imibala eguquliwe ifakwa kwimidiya yezinto eziphilayo, imiketanga ye-hydrocarbon, ehambisana kahle nemidiya yezinto eziphilayo, isheshe incibilike ukuze yakhe ifilimu encibilikile. Lokhu kwenza kube lula ukuhlakazeka kwezinhlayiya ze-pigment futhi kuvimbele ukugobhoza lapho izinhlayiya zisondelana. Lo mphumela uyathuthuka njengoba imiketanga ye-hydrocarbon ikhula futhi ifilimu encibilikile iqina, okusiza ekucwengisiseni izinhlayiya ze-pigment futhi kufezwe ukusatshalaliswa kosayizi wezinhlayiya ezincane. Amaqembu e-hydrophilic ama-surfactants akha ifilimu encibilikile ngemva kokumanzisa, okuvimbela ngempumelelo ukugobhoza phakathi kwezinhlayiya ze-pigment futhi kuthuthukise ukuhlakazeka kwazo.
Ama-surfactants e-fatty amine polyglycerol ether ane-hydrophilicity ephezulu futhi angakha amafilimu aqinile anamanzi. Ngakho-ke, ama-pigment aphathwe ngala ma-surfactants asakazeka kalula emanzini anobukhulu obuncane bezinhlayiya, okubonisa amathuba okusebenzisa athembisayo ekwelapheni ubuso be-pthalocyanine green pigments.
