Iimpawu kunye neeNzuzo
- Ayinayo i-APEO, i-NPEO okanye i-formaldehyde, njl.
- Isakhono esigqwesileyo sokumanzisa kunye nokuhlamba.Ngokucacileyo inokunciphisa ukuxinana komphezulu webhafu kunye nokunyibilikisa, ukusasaza kunye nokukhupha iintlobo ezahlukeneyo zokungcola okunamafutha kunye nokungcola.
- Kwinkqubo yonyango lwangaphambili, kunesiphumo esihle sokunciphisa amafutha kunye nokukhuhla.
- Kwinkqubo yokudaya, kunesiphumo esihle kakhulu sesepha.

IINGCEBISO:
Idayi ezisebenzayo
Ezi dayi ziveliswa ngokusabela kwedayi ye-dichloro-s-triazine ene-amine kumaqondo obushushu kummandla we-25-40 ° C, okukhokelela ekufudukeni kwenye yee-athom zeklorini, ukuvelisa i-monochloro-s-triazine engaphantsi. (MCT) idayi.
Ezi dayi zisetyenziswa ngendlela efanayo kwi-cellulose ngaphandle kokuba, ngenxa yokuba zisebenza kancinci kunedayi ze-dichloro-s-triazine, zifuna ubushushu obuphezulu (80°C) kunye ne-pH (pH 11) yokulungiswa kwedayi kwiselulosi. kwenzeke.
Ezi ntlobo zedayi zineechromogens ezimbini kunye namaqela amabini asebenzayo e-MCT, ke ngoko anobuxhakaxhaka obuphezulu befayibha xa kuthelekiswa nohlobo lwedayi ye-MCT elula.Oku kunyuswa kwamandla okubavumela ukuba bafezekise ukudinwa okugqwesileyo kwifayibha kwiqondo lokushisa elikhethiweyo lokudaya le-80 ° C, elikhokelela kumaxabiso okulungisa ama-70-80%.Iidayi zolu hlobo zazithengiswa kwaye zisathengiswa phantsi koluhlu lweProcion HE lweedayi eziphezulu zokukhupha.
Ezi dayi zaziswa nguBayer, ngoku Dystar, phantsi kwegama Levafix E, kwaye zisekelwe kwindandatho ye-quinoxaline.Zisebenza kancinci kancinci xa zithelekiswa nedayi ze-dichloro-s-triazine kwaye zifakwe kwi-50 ° C, kodwa zichaphazeleka kwi-hydrolysis phantsi kweemeko ze-asidi.
