    Amabara

    Irangi rya solvent ni irangi rishobora gushonga mumashanyarazi kandi rikoreshwa kenshi nkigisubizo muri ibyo bishishwa.Iki cyiciro cy'amabara gikoreshwa mu gusiga amabara nk'ibishashara, amavuta, plastike, n'ibindi bikoresho bya hydrocarubone bishingiye ku bikoresho bidafite inkingi.Irangi iryo ari ryo ryose rikoreshwa mu bicanwa, nk'urugero, byafatwa nk'irangi ryangirika kandi ntibishobora gushonga mu mazi.

    Kurangi amarangi

    Gusiga irangi ni ubwoko bumwe bwibintu bitarimo ionizing group.Ntibishobora gushonga mumazi kandi bikoreshwa mugusiga irangi ibikoresho.Amabara atatanye agera kubisubizo byiza mugihe inzira yo gupfa ibaye mubushyuhe bwinshi.By'umwihariko, ibisubizo bigera kuri 120 ° C kugeza 130 ° C bituma amabara atatanya gukora kurwego rwiza.

    Hermeta itanga amarangi atandukanye hamwe nubuhanga butandukanye bwo gusiga amabara nka polyester, nylon, selile ya acetate, vilene, velveti ya syntetique na PVC.Ingaruka zazo ntizifite imbaraga kuri polyester, kubera imiterere ya molekuline, ituma gusa paste ikanyura mugicucu giciriritse, icyakora ibara ryuzuye rishobora kugerwaho mugihe ubushyuhe bwoherejwe hamwe no gusiga amarangi.Irangi rya disperse naryo rikoreshwa mugucapisha sublimation ya fibre synthique kandi ni amabara akoreshwa mugukora “fer-on” yimura hamwe na wino.Birashobora kandi gukoreshwa mubisumizi na plastiki kubuso hamwe nibisanzwe bikoreshwa.

    Amabara meza

    Irangi ryoroshye ni umuryango wamabara arimo ibyuma bihujwe nigice kama.Amabara menshi ya azo, cyane cyane ayakomotse kuri naphthol, akora ibyuma bigizwe nurwego rumwe rwa azo azote.Irangi ryuma risize irangi ryerekanwe mbere yerekana isano iri hagati ya fibre proteine.Muri iri bara, molekile imwe cyangwa ebyiri irangi ihujwe nicyuma cyicyuma.Molekile y'irangi mubisanzwe ni imiterere ya monoazo ikubiyemo amatsinda yinyongera nka hydroxyl, carboxyl cyangwa amino, zishobora gukora ibice bikomeye byo guhuza hamwe nibyuma byinzibacyuho nka chromium, cobalt, nikel na muringa.
