Amateka Yamabara Yera

Ciba yatangiye kwiga amarangi ya melamine mu myaka ya za 1920.Imikorere yamabara ya melamine iruta amarangi yose ataziguye, cyane cyane Chloramine yihuta yubururu 8G.Ni irangi ry'ubururu rigizwe na molekile zo mu nda zirimo itsinda rya amine hamwe n'irangi ry'umuhondo hamwe n'impeta ya cyanuryl kugira ngo bibe ijwi ry'icyatsi, ni ukuvuga ko irangi rifite atome ya chlorine idafite ishingiro, kandi mu bihe bimwe na bimwe, Irashobora kwitwara kugira ngo ibe ibintu bifatika. , ariko ntibyemewe.

Mu 1923, Ciba yavumbuye ko aside-chlorotriazine irangi irangi ry'ubwoya, kugira ngo hashobore kuboneka umuvuduko mwinshi, bityo mu 1953, havumburwa amarangi yo mu bwoko bwa Ciba Lambrill.Muri icyo gihe, mu 1952, Hirst yanakoze Remalan, irangi ryoroshye ry’ubwoya, bushingiye ku bushakashatsi bwakozwe mu matsinda ya vinyl sulfone.Ariko ayo marangi yombi ntabwo yagenze neza muricyo gihe.Mu 1956, Buneimen yarangije gukora irangi ryambere ryirangi rya pamba, ubu ni irangi rya dichlorotriazine.

Mu 1957, Benemen yakoze irindi rangi rya monochlorotriazine, Procion H.

Mu 1958, Hearst yakoresheje neza amarangi ashingiye kuri vinylsulfone kugirango asige fibre selile, aribyo irangi rya Remazol.

Mu 1959, Sandoz na Cargill bakoze kumugaragaro irindi tsinda ryirangi, trichloropyrimidine.Mu 1971, hashingiwe kuri, irangi ryitwa difluorochloropyrimidine rifite imikorere myiza ryakozwe.Mu 1966, Ciba yakoze irangi ridasubirwaho rishingiye kuri a-bromoacrylamide, ifite imiterere myiza yo gusiga ubwoya kandi ishyiraho urufatiro rwo gukoresha amarangi yihuta cyane yubwoya mugihe kizaza.

Mu 1972, i Baidu, Benemen yakoze irangi rifite amatsinda abiri adashingiye ku marangi ya monochlorotriazine, ari yo Procion HE.Irangi ryarushijeho kunozwa mubijyanye na reactivite hamwe na fibre fibre hamwe nigipimo cyo kugena.

Mu 1976, Bunaimen yakoze icyiciro cyamabara hamwe na acide fosifonique nkitsinda rikora.Irashobora gukora covalent hamwe na fibre ya selulose mugihe kitarimo alkali, kandi irakwiriye cyane cyane gucapa paste yo koga, ikaba ari kimwe no gusiga irangi.Izina ry'ubucuruzi ni Pushian t.Mu 1980, hashingiwe ku irangi rya vinyl sulfone Sumifix, Isosiyete ya Sumitomo yo mu Buyapani yateje imbere vinyl sulfone Na monochlorotriazine irangi ryibiri.

Mu 1984, Isosiyete ya Nippon Kayaku yakoze irangi ryitwa Kayasalon, ryongeramo niacin risimbuza impeta ya triazine.Irashobora kwifata neza hamwe na fibre ya selile mugihe cy'ubushyuhe bwinshi no mubihe bidafite aho bibogamiye, kandi irakwiriye cyane cyane ubushyuhe bwo hejuru hamwe no gukwirakwiza umuvuduko mwinshi / irangi ryirangi irangi ryogejwe rimwe ryo gusiga irangi rya polyester-ipamba.

Turi abatanga amabara meza.Niba ushimishijwe nibicuruzwa byacu, nyamuneka twandikire.
