Yiziphi odayi be-Cationic?

Odayi be-cationicingahlukaniswa ibe ama-ion ane-positively charged in aqueous solution.Angakwazi ukuxhumana namaqembu angalungile kuma-molecule e-fiber ukuze enze usawoti, ongaqhubeka unamathele ngokuqinile emicubu, ngaleyo ndlela ungcolise imicu.Odayi be-cationic bathuthukiswe ngempumelelo ngokusekelwe kudayi we-alkaline.Umgomo ongcolile wamadayi we-cationic ukudaya imicu ngokuhlanganisa ama-cations awo namaqembu ane-acidic ku-monomer yesithathu ye-acrylon, ngaleyo ndlela kubangele ukushesha okuphezulu.

Izinhlelo zokusebenzaUdayi weCation:

1.Ukudaya imicu yokwenziwa: Udayi we-Cations kukhonaIsetshenziswa kakhulu ekudayweni kwe-polyester fibre kanye ne-acrylic fiber.I-cationic chromophore iqala ukumuncwa i-fiber surface ngogesi ongemuhle bese isakazekela ngaphakathi kwefayibha ngezinga lokushisa eliphakeme;ibophezela emaqenjini e-asidi esebenzayo kodwa ukufinyeleleka kwayo kuncike ekushiseni nasekubunjweni kwefiber.Ngakho-ke, izici zokudaya zamadayi we-cationic zinqunywa ukuhambisana nokuhlukana.

2.Ukudaywa kwephephafuthiisikhumba: Odayi be-Cationic banikeza ukuhlobana okuhle kwe-pulp yezinkuni ezikhokhiswa kabi kanye namamaki e-pulp angaxutshiwe.Odayi be-Cationic bakhethwa ngenxa yobuhlakani babo nokuqina, okubenza basebenziseke kakhulu kumamaki ephepha agaywe kabusha.Odayi be-Cationic bangabadayi bokuqala bokwenziwa abasetshenziswa ukudaya isikhumba futhi ekuqaleni babesetshenziselwa ukudaya izikhumba zokushuka zemifino.Zibuye zisetshenziselwe ukukhiqiza amaribhoni omshini wokubhala kanye nephepha lokukopisha.
