Ukusetshenziswa Kwe-ejenti Yokulinganisa Udayi Ehlakazekile Ekudayeni nasePolyester

Odayi be-Disperse basetshenziselwa ikakhulukazi ukudaya imicu ye-hydrophobic efana ne-polyester, i-spandex, inayiloni, nemicu ye-acetate. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokudaya i-fiber, izinhlobo ezahlukahlukene zama-ejenti wokulinganisa zenze inqubekelaphambili enkulu.

1. I-ejenti yokulinganisa yokudaya okunezinga lokushisa eliphezulu

Uma usebenzisa odayi abahlakazekile ngokudaya okunezinga lokushisa eliphezulu nokucindezela okuphezulu, ukudaya okungalingani kuvame ukubangelwa izici ezifana nokuhlakazeka okubi, ukufana, nokudluliswa kodayi, kanye nokulawulwa okungalungile kwezinga lokushisa. Ikakhulukazi emiculweni ye-polyester emihle, ukuminyana komugqa kuphansi kakhulu, indawo engaphezulu iyanda, futhi ijubane lokudaya likadayi liyashesha. Ngaphezu kwalokho, ukwakheka kwendwangu eqinile kwenza kube nzima ukuthi odayi bangene, okuholela ekungalinganini kokudaya okuvelele kunemicu ye-polyester evamile. Ukusetshenziswa kwama-agent okusabalalisa izinga lokushisa okuphezulu ngesikhathi sokudaya kungathuthukisa umphumela wokulinganisa wezindwangu futhi kuthuthukise ikhwalithi yomkhiqizo.

Ngokuvamile, ama-surfactants angewona ama-ionic angasetshenziswa njengama-leveling odayi abahlakazekile abangewona ama-ionic, angakha amabhondi e-hydrophobic futhi anciphise isivinini sokudaya ukuze kufinyelelwe izinga. Phakathi kwama-non-ionic dispersing leveling agents, ama-polyoxyethylene ester surfactants asebenza kangcono kunama-polyoxyethylene ether surfactants (izakhiwo ze-ester zinokuhambisana okukhulu kwe-polyester kunezakhiwo ze-ether), futhi ama-surfactants anezindandatho ze-benzene asebenza kangcono kuleveli kunama-fatty surfactants.

Kodwa-ke, ama-non-ionic surfactants athambekele ekuphelelweni amanzi emzimbeni ngesikhathi sokudaywa kwe-polyester ngezinga lokushisa eliphezulu, futhi ukubopha phakathi kwamaketanga e-ethylene oxide kanye ne-hydroxyl, i-amino, namanye amaqembu asebenzayo kuma-molecule odayi kuwukukhanyiswa okuxekethile ngokomzimba, ukuntula amandla okusebenzelana kwe-ion kanye nokuhlakazeka okungekuhle kanye ne-solubilization. Uma usebenzisa i-low cloud point non-ionic surfactants, ukuhlanganisa udayi kungenzeka kakhulu. Ngenxa yesendlalelo esinamandla sokushaja esingalungile esakhiwe ukukhangiswa kwama-anionic surfactants ebusweni bezinhlayiya zikadayi, kukhona ukwenyanya okunamandla kukagesi phakathi kwezinhlayiya zikadayi ukuze kwakheke isimo esihlakazekile esizinzile, esinamandla okuhlakazeka okuqinile kuma-agglomerates odayi abahlakazekile, ngaleyo ndlela kunciphisa ukuhlangana kwabo nokugcina udayi odayini. Lokhu kungaxazulula inkinga yezindawo zikadayi ezibangelwa indawo ephansi yamafu yama-nonionic surfactants.

I-ejenti yokulinganisa izinga lokushisa eliphezulu esebenza kahle kakhulu yenziwa ngokusebenzisa imithelela ye-synergistic kanye ne-synergistic yama-non-ionic kanye nama-anionic surfactants, lapho izakhiwo ezihlukene zengxenye ngayinye zinemiphumela ehlukile. Kunemikhiqizo eminingi yokukhiqiza izinga lokushisa eliphezulu (eminye yayo ehlanganisa nezinkampani zenethiwekhi) eyenziwe ngama-anionic/nonionic surfactants. Izakhiwo ezihlukene zengxenye ngayinye zinemisebenzi ehlukene, ikakhulukazi ihlukaniswe yaba: 1) isakhiwo se-ethoxy singathwebula odayi abahlakazekile, sandise amasayithi odayi, futhi sibambezele ukudaya ngesikhathi senqubo yokudaya; I-2) Lapho izinga lokushisa lokudaya lifinyelela inani elibalulekile, izinhlanganisela ezinuka kamnandi zingabangela ngokushesha ukwenziwa kwepulasitiki nokuvuvukala kwemicu ye-polyester, kunciphise izinga lokushisa lengilazi le-polyester ngo-20-25 ℃, okwandisa kakhulu ama-pores ngaphakathi kwemicu, futhi kuvumele odayi ukuba badaye ngokushesha futhi ngokugxila imicu. Ngasikhathi sinye, zingasebenza njengama-solvents ukuze odayi baqhubeke bencibilika futhi bahlukane nemicu, okuholela ekufudukeni okubalulekile (ukudlulisa ukudaya) ukuze kuzuzwe umphumela wokudaya ofanayo.

Eminye yemikhiqizo eyinkimbinkimbi yama-surfactants inezinto ezikhipha amagwebu amaningi, ezingabangela kalula izinkinga emishinini yokudaya ngokushesha kanye nokudaya okuncane okugeza. Ngakho-ke, ama-ejenti okwehlisa amagwebu aphansi ayadingeka. Isixazululo ukufaka ama-defoamers, ikakhulukazi ama-organosilicon defoamers, asebenza kahle kakhulu emazingeni okushisa aphezulu; Imikhiqizo enegwebu eliphansi itholakala nge-copolymerizing ethylene oxide ne-propylene oxide.
