Unozivei Nezvedhayi dzeSulfur(1)?

madhayi esarufa madhayi anonyungudutswa mualkali sarufa.Iwo anonyanya kushandiswa kudhaya machira edonje uye anogona zvakare kushandiswa kugadzira machira akasanganiswa edonje/vitamini.Mutengo wakaderera, dhayi inowanzokwanisa kugeza uye nekukurumidza, asi ruvara haruna kupenya zvakakwana.Zvinowanzoshandiswa mhando dziriSulfur Blue 7,Sulfur Tsvuku 14 Sulfur Black Bluishandzvichingodaro.Soluble sulfur dhayi dzava kuwanikwa.Dhayi inogadzirwa neiyo vulcanization reaction yemamines, phenols, kana nitro makomisheni eanonhuwirira hydrocarbons ane sarufa kana sodium polysulphur,

peculiarity

Dhayi dzesarufa hadzina kunyungudika mumvura, uye sodium sarufa kana zvimwe zvinoderedza zvinoshandiswa kudzikisa madhayi kunyungudika leucochromes.Iyo ine hukama kune fiber uye inosvibisa iyo fiber, uyezve inodzoreredza iyo insoluble mamiriro neoxidation uye kugadzirisa pane fiber.Saka dhayi yesarufa zvakare idhayi yeVAT.Madhayi ane vulcanized anogona kushandiswa kudhayi donje, hemp, viscose uye mamwe mafiber, maitiro ayo ekugadzira ari nyore, mutengo wakaderera, anogona kuvezwa monochrome, asi zvakare anogona kuve akasanganiswa ruvara, kukurumidza kupenya kwezuva, kutadza kukurumidza kupfeka.Chromatographic kushaya tsvuku, yepepuru, yakasviba ruvara, yakakodzera kudhaya yakasimba ruvara.

sort

Zvinoenderana neakasiyana mamiriro ekudhaya, dhayi dzesarufa dzinogona kukamurwa kuita dhayi dzesarufa ine sodium sulfur seanoderedza ajenti uye sarufa VAT madhayi ane sodium disulfite seanoderedza agent.Kuti ushandise zviri nyore, boka re sulfonic acid rinotsiviwa ne sodium metabisulfite kana sodium formaldehyde bisulfite (zita rinowanzozivikanwa) kuwana mvura-inonyunguduka sulfur dhayi, iyo inogona kushandiswa zvakananga kudhaya pasina kuderedza agent.

(1) madhayi esarufa achishandisa sodium sarufa sechinhu chinoderedza;

(2) sulfur kuderedza dhayi (inozivikanwawo seHaichang dyes) nehupfu yeinishuwarenzi semugadziri wekudzikisa;

(3) Mvura yesarufa dhayi imhando itsva yedhayi yesarufa yakagadzirwa uye inogadzirwa kuti igadziriswe zviri nyore.

Kushandiswa kwedhayi dzakadaro kwakafanana nedhayi inonyungudika yeVAT, iyo inogona kuderedzwa zvakananga nemvura zvichienderana nekugadzirisa, pasina kuwedzera kuderedza vamiririri, uye imwe sarufa yesodium inofanira kuwedzerwa kana chikamu chemuvara chiri chiedza.Iyi mhando yedhayi chromatography yakakura, kune yakatsvuka, yepepuru brown, Hu yegirini.

Bereka

Kune nzira mbiri dzekugadzira maindasitiri edhayi resarufa: ① nzira yekubikira, iyo mbishi inonhuhwirira mamines, phenols kana nitro nyaya uye sarufa kana sodium polysulphur pakupisa kwekushisa kwepamusoro, kuitira kugadzira yero, orenji, dhayi resarufa.② Nzira yekubikira, maamine, phenols kana nitro zvinhu zvemahydrocarboni anonhuwirira uye sodium polysulphur zvinopiswa uye zvinobikwa mumvura kana organic zvinonyungudutsa kuti vawane dema, bhuruu uye girini vulcanization dyeing.

nature

1, yakafanana nedhayi dzakananga

(1) munyu unogona kushandiswa kukurudzira kudhaya.

(2), cationic color fixing agent uye simbi munyu ruvara kugadzirisa mumiririri kunatsiridza kukurumidza.

2, yakafanana neVAT dhayi

(1), dhayi inoda kudzikiswa kuti iite leachite ine inoderedza mumiriri kuti idhaye fiber uye oxidize pane fiber.Panzvimbo peiyo yakasimba yekudzikisa mumiriri, sodium sulfur ishoma inoderedza mumiriri.Nekudaro, iyo yakananga pfuma yeleaches kune fiber mushure mekuderedzwa yakaderera pane iyo yeVAT dhayi, uye tsika yekuunganidza dhayi yakakura.

(2) Kuita neasidhi kunogona kuburitsa gasi reH2S, uye kuita nealuminium acetate kunogona kuburitsa dema aluminium sulfur precipitation.

3, tembiricha yepamusoro inogona kushandiswa kuvandudza mwero wekupararira kwedhayi uye kugadzirisa dhigirii rekupinda.
