Izici ze-disperse dyes:
Ngokungafani nezinye izinhlobo eziningi zamadayi, odayi abahlakazayo abancibiliki kalula emanzini kunabanye odayi abanjengodayi be-asidi. Ngakho-ke, odayi abahlakazayo bavame ukusetshenziswa kakhulu ekudayeni izixazululo zokugeza.Tamol NNisebenza kangcono uma inqubo yokudaya yenziwa emazingeni okushisa aphezulu. Ikakhulukazi, izixazululo ezingaba ngu-120°C kuya ku-130°C zinikeza ukusebenza okuphelele ukuze kuhlakazwe odayi, kubenze basakazwe ngokulinganayo futhi bahehe, kuyilapho.Tamol NNkungase kubangele umbala ongalingani futhi ungabi nemibala emazingeni okushisa aphansi.
Yiziphi ukusetshenziswa kodayi be-disperse?Tamol NN
Ngenxa yezakhiwo zawo zamakhemikhali nokuziphatha okuchazwe ngenhla, odayi abahlakazayo bavame ukusetshenziselwa ukudaya imicu yokwenziwa, njenge-polyester, inayiloni, i-acrylic, ne-acetate. Izinhlobo eziningi ze-polyester ziyi-hydrophobic futhi ayinazo izakhiwo ze-ionic, okwenza kube cishe akunakwenzeka ukufaka imibala nganoma yini enye ngaphandle kokusabalalisa odayi.
Ngaphezu kwalokho, imicu ye-polyester ayikhuli emazingeni okushisa avamile ngisho nalapho icwiliswa endaweni yokugezela edayi, okwenza kube nzima ngama-molecule odayi ukuthi axhumane nezinto. Ngisho nasemazingeni okushisa (100°C), ukudaywa kwe-polyester kunezinkinga.
Ngakho-ke, lapho kudaywa i-polyester, odayi abahlakazayo basetshenziswa ekudayeni izixazululo zokugeza emazingeni okushisa angama-20 kuya ku-30 degrees ngaphezu kwendawo yokubilisa yezixazululo zokugeza zokudaya. Odayi abahlakazayo baziwa ngokugcina ubuqotho bamangqamuzana emazingeni okushisa aphezulu adingekayo ukuze kufakwe imibala kuma-polyester. Ngesizathu esifanayo amadayi ahlakazayo asetshenziselwa ukudaya ama-polyester, asetshenziselwa ukudaya ezinye izinto zokwenziwa ezingezona i-ionic. Iqiniso lokuthi odayi abahlakazayo abanawo ukuthambekela kwe-cationic noma i-anionic cishe impahla ehlukaniswa kakhulu yodayi abahlakazayo.
Udayi we-Disperse nawo ungasetshenziswa kuma-resin namapulasitiki ngezinjongo zokufaka imibala ezingaphezulu nezijwayelekile.
