Umlando Wezidayi Ezisebenzayo

UCiba waqala ukufunda ngodayi be-melamine ngawo-1920.Ukusebenza kodayi be-melamine kungcono kunabo bonke odayi abaqondile, ikakhulukazi i-Chloramine Fast Blue 8G.Idayi eluhlaza okwesibhakabhaka eyakhiwe ngama-molecule abophayo angaphakathi aqukethe iqembu le-amine kanye nodayi ophuzi onendandatho ye-cyanuryl ukuze enze ithoni eluhlaza, okungukuthi, udayi unama-athomu e-chlorine angashintshiwe, futhi ngaphansi kwezimo ezithile, Ingasabela ukwenza izakhi ezihlangene. , kodwa ayaziwa.

Ngo-1923, uCiba wathola ukuthi odayi be-acid-chlorotriazine abadaya uvolo, ukuze kutholakale ukushesha okumanzi, ngakho ngo-1953, kwasungulwa odayi bohlobo lwe-Ciba Lambrill.Ngaso leso sikhathi, ngo-1952, u-Hirst uphinde wakhiqiza i-Remalan, idayi esebenzayo yoboya, ngokusekelwe ekutadisheni kwamaqembu e-vinyl sulfone.Kodwa laba odayi ababili abaphumelelanga kakhulu ngaleso sikhathi.Ngo-1956, i-Buneimen yagcina ikhiqize udayi wokuqala osebenzayo i-Procion kakotini, manje osekuwudayi we-dichlorotriazine.

Ngo-1957, u-Benemen wenza omunye udayi osebenzayo we-monochlorotriazine, i-Procion H.

Ngo-1958, u-Hearst wasebenzisa ngempumelelo odayi abasebenzisa i-vinylsulfone ukuze adaye imicu ye-cellulose, okuyi-Remazol dyes.

Ngo-1959, uSandoz noCargill bakhiqiza ngokusemthethweni omunye udayi weqembu osebenzayo, i-trichloropyrimidine.Ngo-1971, ngalesi sisekelo, udayi we-difluorochloropyrimidine osebenzayo osebenza kangcono wasungulwa.Ngo-1966, i-Ciba yenza udayi osebenzayo osuselwe ku-a-bromoacrylamide, onezici ezinhle zokudaya eboyeni futhi wabeka isisekelo sokusebenzisa odayi abashesha kakhulu eboyeni esikhathini esizayo.

Ngo-1972, e-Baidu, u-Benemen wakha idayi enamaqembu amabili asebenzayo asekelwe kumadayi asebenzayo e-monochlorotriazine, okuyi-Procion HE.Udayi uthuthukisiwe futhi ngokuya ngokusebenza kabusha nge-cotton fiber kanye nesilinganiso sokulungisa.

Ngo-1976, iBunaimen yakhiqiza ikilasi likadayi elinamaqembu e-phosphonic acid njengamaqembu asebenzayo.Ingakha isibopho esihlangene ne-cellulose fiber ngaphansi kwezimo ezingenayo i-alkali, futhi ifaneleka ngokukhethekile ukuphrinta unamathisele okugeza, okufana nokuhlakaza ukudaya kodayi.Igama lokuhweba nguPushian t.Ngo-1980, ngokusekelwe kudayi we-vinyl sulfone Sumifix, i-Sumitomo Corporation yaseJapane yenza i-vinyl sulfone Kanye nodayi we-monochlorotriazine osebenza kabili osebenzayo.

Ngo-1984, Inkampani ye-Nippon Kayaku yakha udayi osebenzayo obizwa ngokuthi i-Kayasalon, owengeza indawo ye-niacin endandatho ye-triazine.Ingakwazi ukusabela ngokuhlanganyela ngemicu ye-cellulose ngaphansi kwezimo eziphakeme zokushisa nezimo ezingathathi hlangothi, futhi ifaneleka ngokukhethekile izinga lokushisa eliphezulu kanye nomfutho ophezulu wokuhlakazeka/ukudayi osebenzayo odayiweyo wokugeza owodwa wezindwangu ezihlanganisiwe zikakotini we-polyester.

Singabahlinzeki be-Reactive Dyes.Uma unentshisekelo ngemikhiqizo yethu, sicela ukhululeke ukuxhumana nathi.
