Ukutadisha Ngokulungiswa Kwe-Waterborne Polyurethane Leather Finishing Isithombe Esifakiwe

Ukufunda Ngokulungiswa Kwesikhumba Se-Waterborne Polyurethane

Incazelo emfushane:

Enkambweni yokukhiqizwa kwesikhumba, ukuqeda kuyinqubo ebaluleke kakhulu, enomthelela obaluleke kakhulu ekusetshenzisweni kwenani lesikhumba.Ngokuthuthuka komnotho kanye nokuthuthuka okuqhubekayo kwamazinga okuphila abantu, abantu banezidingo eziphakeme neziphakeme zama-agent aqeda isikhumba, futhi eminyakeni yamuva, kancane kancane baye basondela ohlotsheni oluvumelana nemvelo.I-ejenti yokuqeda isikhumba se-polyurethane emanzini ingagwema ngokuphumelelayo ukungcola kanye nobuthi be-ejenti yokuqedela yendabuko, futhi inezici zokugcinwa okulula, ukuthutha nokungashisi.Inokusebenza okuhle kakhulu, kodwa isenakho ukushiyeka kokungaguquki nokumelana namanzi.Idinga abasebenzi abafanelekile ukuze bahlole futhi balungise i-ejenti yokuqedela lesikhumba ye-polyurethane emanzini.

Ukuguqulwa Kwe-ejenti Yokuqeda Isikhumba Se-Waterborne Polyurethane

Khetha ubumba lwe-attapulgite u-10g, engeza i-100ml ye-hydrochloric acid ene-concentration ye-1mol / L obumbani, uhlanganise kokubili, ugovuze amahora angu-24, bese uzipholisa phansi.Khona-ke, i-filtrate igezwa ngamanzi a-distilled ukuze i-filtrate ingasaqukethe i-chloride ion.I-filtrate yomiswa kuhhavini enezinga lokushisa elingu-100 ° C. ngemva kokulinda amahora angu-24, igaywe ibe yimpuphu.Ngakho, i-attapulgite ephathwa nge-asidi iyatholakala.

Ukuguqulwa Kwe-Waterborne Polyurethane Resin Lotion Nge-Attapulgite

Lungiselela i-attapulgite ephathwe nge-asidi ibe yi-dispersion enengxenye enkulu engu-10%, sebenzisa ukuxubana kwe-electromagnetic amahora amabili, bese uqhuba ukusabalalisa kwe-ultrasonic ihora elilodwa.Bese, engeza i-aqueous polyurethane resin lotion ekuhlakazweni ngaphansi kwezimo ezinyakazayo, lapho ingxenye enkulu ye-aqueous polyurethane resin lotion ingu-20%, Okuqukethwe kwe-attapulgite ephathwe nge-asidi kulawulwa ukuthi kube phakathi kuka-0.1% no-5% we-polyurethane esekelwe emanzini. i-resin lotion, okubili kuvunyelwe ukusabela ku-70 ℃ amahora amane, bese umkhiqizo ugxiliswa cishe ku-20% ngokusebenzisa i-evaporator ejikelezayo.Ngakho-ke, ukuguqulwa kwe-polyurethane resin lotion yamanzi ngokusebenzisa ubumba lwe-attapulgite kuqale kubonakale.Kamuva, ifilimu yenziwa ngokusetshenziswa komkhiqizo oshintshiwe, futhi i-20g yomkhiqizo yafakwa ekubunjweni kwe-polytetrafluoroethylene ukuze kuzuzwe ukwenziwa kwefilimu.
