Irangi risize irangi

Abatanga amarangi meza kugirango bamenyekanishe ibiranga amarangi meza kuri wewe

1. Gukemura

Irangi rifatika rifite amazi meza yo gukemura.Ubusembure hamwe nubunini bwirangi ryateguwe bifitanye isano nigipimo cyo kwiyuhagira, ingano ya electrolytite yongeweho, ubushyuhe bwo gusiga irangi nubunini bwa urea yakoreshejwe. cyangwa irangi rya padi irangi ryirangi, rigomba gutoranywa mugukemura kwubwoko butandukanye bwa g / l 100, ibisabwa kugirango irangi ryuzuye ryuzuye, nta mivurungano, ntamabara afite. nka sodium, ifu ya sodium electrolytite izagabanya ubukana bwamabara.Alkali ntigomba kongerwaho icyarimwe mugihe irangi rishonga ryashonga kugirango birinde hydrolysis y irangi.

2. Gutandukana

Diffusivite bivuga ubushobozi bwirangi ryimuka muri fibre, kandi ubushyuhe bufasha gukwirakwiza molekile zirangi. Irangi hamwe na coefficient nini yo gukwirakwiza rifite umuvuduko mwinshi hamwe nuburyo bwo gutunganya amabara, kandi urugero rwuburinganire no kwinjira ni byiza .Ikwirakwizwa riterwa n'imiterere n'ubunini bw'irangi.Ku fibre ifitanye isano ya fibre na fibre adsorption imbaraga irakomeye, gukwirakwizwa biragoye, mubisanzwe nukwongera ubushyuhe kugirango byihute gukwirakwiza irangi. Coefficient de diffuzione yamabara igabanuka iyo electrolyte yongewe mubisubizo by'irangi.

3. Ubuyobozi

Ubuyobozi bwerekeza ku bushobozi bwo gusiga amarangi adashobora kwinjizwa na fibre mu gisubizo cy’irangi. Ubushobozi bwo gusiga amarangi burashobora kuba buke butaziguye, buhoraho bwo gusiga amarangi no gucapa bigomba guhitamo ubwoko buto butaziguye. Kubikoresho byo gusiga irangi bifite igipimo kinini cyo kwiyuhagira, nka Irangi rimeze nk'irangi hamwe no gusiga irangi rya Hank, hagomba guhitamo irangi ryinshi ryerekanwa. Uburyo bwo gusiga irangi (gukonjesha gukonje) uburyo bwo gusiga irangi, irangi ryimurirwa muri fibre binyuze mukuzunguruka, nanone hamwe nubuyobozi buke bwo hasi bwirangi biroroshye kuba bingana. irangi, mbere na nyuma yo gutandukanya ibara ni rito, irangi rya hydrolysis ryoroshye gukaraba.

4. Gukora neza

Ubusanzwe irangi ryirangi risanzwe ryerekana irangi rya hydroxy ya hydroxy ya selile hamwe na selile, imbaraga zikomeye, Irangi rifite imbaraga mubushyuhe bwicyumba, mugihe hashingiwe ku ntege nke aribyo gukosorwa birashobora gukorwa, ariko reaction yumutuku w irangi irakennye cyane, byoroshye hydrolysis gutakaza ubushobozi bwo gusiga irangi. Amabara meza agomba guhuza na selile mugihe cy'ubushyuhe bwo hejuru, cyangwa ugakoresha alkali ikomeye kugirango ukoreshe hydroxyl groupe ya fibre yintambara, kugirango reaction yo gusiga irangi kuri fibre.

Gutezimbere amarangi

Kugirango uhuze ibyifuzo byo gusiga irangi, amarangi mashya yagiye ahora agaragara mumyaka yashize.Iterambere ryamabara mashya ahanini ryujuje ibisabwa bikurikira:

(1) gusimbuza amarangi yabujijwe no guteza imbere irangi ryangiza ibidukikije;

(2) guhuza n'ibikenewe bya fibre nshya no gusiga imyenda myinshi;

(3) guhuza ibikenewe n'ikoranabuhanga rishya no gutunganya ibikoresho bishya;

(4) guhaza ibikenewe gutunganya neza, kuzigama amazi no kuzigama ingufu.

Iterambere ryirangi ryamabara ririmo chromofore nshya, amatsinda yitabira hamwe no guhuza kwayo muri molekile, no kuvanga ligande hamwe n amarangi atandukanye.Mubyongeyeho, nyuma yo gutunganya amarangi yubucuruzi yaratejwe imbere cyane.Imikorere yamabara mashya yerekana cyane cyane muri:

(1) ubukana bwamabara menshi, kuyobora cyane no gukosora;

(2) kwihuta cyane, harimo kwihuta kwizuba, guterana, ibyuya, chlorine nisabune, nibindi.;

(3) umunyu muke, alkali nkeya cyangwa kutagira aho ubogamiye no gutunganya;

(4) bitangiza ibidukikije, bitarimo amine yangiza yangiza, ibyuma biremereye, fordehide nibindi bintu;

(5) urwego rwiza, kubyara no guhuza.
