Inkcazo
I-EX emnyama ngokuthe ngqo yidayi ethe ngqo, ngendlela yomgubo omnyama onzulu, inokuchithwa ngokuthe ngqo emanzini, i-molecule iqulethe iqela le-sulfonic acid, inokudaywa ngokuthe ngqo kwiimeko ezingathathi hlangothi kwimicu ye-cellulose, ine-directivity ephezulu kwi-cellulose, ngaphandle kokusetyenziswa. yeendlela zekhemikhali.Kwishishini lelaphu lihlala lisetyenziselwa ukudaya imicu yendalo, enjengoboya, isilika, kodwa ikwasetyenziswa kumqhaphu, ihempe, isilika yerayon, idayi yomqhaphu.
Umlinganiswa wemveliso
Uphawu lwemveliso ye-Direct emnyama EX ibandakanya:
Ifom ebonakalayo: I-EX emnyama ngqo yidayi engumgubo enyibilika emanzini.
Ukwakheka kweekhemikhali: Umgubo omdaka omnyama onyibilika emanzini kukukhanya okuluhlaza okumnyama, ukunyibilika kancinane kwi-ethanol, ukukhanya okuluhlaza okuluhlaza okwesibhakabhaka kumnyama, ukunyibilika kwi-lysofibrin, okunganyibiliki kwezinye izinyibilikisi zendalo.Kwimeko ye-asidi yesulfuric egxininisiweyo inombala obomvu obomvu, emva kokuxutywa ngumbala omfusa we-paste ukuya kwimvula ebomvu emnyama;Isisombululo esityheli-mdaka kwi-asidi ye-nitric egxininisiweyo;Isisombululo esimnyama esimnyama esimnyama kwi-concentrated hydrochloric acid.Isinyibiliko saso esinamanzi esine hydrochloric acid exutyiweyo savuthuluka ngombala omfusa.Xa isisombululo se-sodium hydroxide songezwa, imvula engwevu iyenziwa.Ukudaya ifayibha ye-cellulose, ukufunxwa kwedayi kulungile kakhulu, obona buhlobo buphezulu kwi-80 ℃.Ukudaya kunokwenziwa.
Ukusetyenziswa: Isetyenziselwa ukudaya ifayibha, umqhaphu, ihemp, isilika yerayon kunye nomqhaphu we rayon njalo njalo.
Iimpawu eziphambili
Iimpawu eziphambili ze-Direct Black ziquka:
A.Idayi ezithe ngqo zisetyenziswa kakhulu ekudayeni umqhaphu kunye neefiber zeviscose.
B.Olu hlobo lwedayi luthe ngqo kwifiber ye-cellulose kwaye lunokudaywa ngokuthe ngqo.
C. Idayi ezithe ngqo zitshiphu, inkqubo yokudaya elula, ichromatography epheleleyo, umbala oqaqambileyo, into embi kukuba unyango olumanzi fastness of ukudaya ayilunganga, ngokubanzi ngokulungisa unyango arhente ukuphucula, fastness ukukhanya kwelanga yahluke kakhulu ngeentlobo zedayi.
Isicelo
Isetyenziswa kakhulu ukwenza iphepha lokudaya, Ingasetyenziselwa ukudaya isilika yerayon kunye noboya njalo njalo.
Ukupakisha
I-25KGS PP Ibhegi / Ingxowa yeKraft / Ibhokisi yeBhokisi / Igubu lentsimbi
UGcino & noThutho
Imveliso kufuneka igcinwe emthunzini, kwindawo eyomileyo kwaye engena umoya.Kuphephe ukudityaniswa neekhemikhali ze-oxidizing kunye nezinto ezinokutsha ze-organic.Yigcine kude nelanga elithe ngqo, ubushushu, iintlantsi kunye namadangatye avulekileyo.Yiphathe ngokucophelela imveliso kwaye ugweme ukulimaza ipakethe.
