Chii Chaunoziva Nezvemadhayi eSulfur(1)?

Dhayi dzesarufa idhayi dzinonyungudutswa mualkali sarufa. Dzinonyanya kushandiswa pakudhaya machira edonje uye dzinogona kushandiswawo pakugadzira machira akasanganiswa nedonje/mavhitamini. Mutengo wakaderera, dhayi inowanzo kwanisa kusukwa uye inosuka nekukurumidza, asi ruvara haruna kupenya zvakakwana. Mhando dzinowanzoshandiswa ndidzoBhuruu reSulfur 7,Tsvuku yeSulfur 14 Sarufa Nhema Bluishandzvichingodaro. Madhayi esulfure anonyungudika ava kuwanikwa. Dhayi inoumbwa nekuita kwe vulcanization kwemamine, phenols, kana nitro compounds yemahydrocarbons ane sarufa kana sodium polysulphur,

chinhu chinoshamisa

Madhayi esulfure haanyungudike mumvura, uye sodium sulfure kana zvimwe zvinoderedza madhayi zvinoshandiswa kuderedza madhayi kuita ma leucochrome anonyungudika. Ane hukama nefiber uye anosvibisa fiber, uye obva adzorera mamiriro ayo asinganyungudike nekuoxidation uye kunamira pafiber. Saka dhayi resulfure idhayi reVAT zvakare. Madhayi eVulcanized anogona kushandiswa pakudhaya donje, hemp, viscose nedzimwe fibers, maitiro ayo ekugadzira ari nyore, anodhura zvishoma, anogona kudhayiwa monochrome, asiwo anogona kuve neruvara rwakasanganiswa, haasviki pachiedza chezuva, haasviki pakumhanya zvakanyanya. Kushaikwa kwechromatographic kwetsvuku, pepuru, ruvara rwakasviba, kwakakodzera kudhaya ruvara rwakasimba.

ronga

Zvichienderana nemamiriro akasiyana ekudhaya, madhayi esulfur anogona kukamurwa kuita madhayi esulfur ane sodium sulphur se reducing agent uye madhayi eVAT esulfur ane sodium disulfite se reducing agent. Kuti zvishandiswe zviri nyore, boka resulfonic acid rinotsiviwa nesodium metabisulfite kana sodium formaldehyde bisulfite (zita rinozivikanwa) kuti pave nedhayi resulfur rinonyungudika mumvura, iro rinogona kushandiswa zvakananga pakudhaya pasina reducing agent.

(1) madhayi esarufa anoshandisa sodium sulphur semushonga unodzikisa ganda;

(2) madhayi ekuderedza sarufa (anozivikanwawo semadhayi eHaichang) ane hupfu hweinishuwarenzi semushonga wekuderedza;

(3) Dhayi yesulfure yemvura rudzi rutsva rwedhayi yesulfure yakagadzirwa uye inogadzirwa kuti ishandiswe zviri nyore.

Kushandiswa kwemadhayi akadaro kwakafanana nemadhayi eVAT anonyungudika, anogona kusanganiswa nemvura zvakananga zvichienderana nechimiro, pasina kuwedzera zvinoderedza ruvara, uye sodium sulphur inofanira kuwedzerwa kana chikamu cheruvara chiri chakajeka. Rudzi urwu rwedhayi chromatography rwakafara, kune matsvuku akajeka, tsvuku yepepuru, girini yeHu.

Kubereka

Kune nzira mbiri dzekugadzira madhayi esulfure mumaindasitiri: 1. Nzira yekubika, aromatic amines, phenols kana nitro matter uye sulfur kana sodium polysulphur pakupisa kwakanyanya, kuitira kuti pave nedhayi yesulfure yeyero, orenji, brown. 2. Nzira yekubikira, amines, phenols kana nitro substances dzemahydrocarbons aromatic uye sodium polysulphur dzinodziiswa uye dzinobikwa mumvura kana organic solvents kuti pave ne vulcanization dyeing nhema, bhuruu negirini.

zvakasikwa

1, yakafanana nedhayi dzakananga

(1) munyu unogona kushandiswa kukurudzira kudhayiwa.

(2), chinhu chinogadzirisa mavara etsinga uye chinhu chinogadzirisa mavara esimbi munyu kuti chiwedzere kukurumidza.

2, yakafanana nedhayi dzeVAT

(1), dhayi inofanira kuderedzwa kuita leachite nechinhu chinodzikisa kuti idhaye fiber uye oxidize pafiber. Panzvimbo pechinhu chinodzikisa chakasimba, sodium sulphur chinhu chinodzikisa chisina simba. Zvisinei, hunhu hwe leaches kune fibers mushure mekuderedzwa hwakaderera pane hweVAT dyes, uye maitiro ekubatanidza dhayi akakura.

(2) Kusangana neasidhi kunogona kuburitsa gasi reH2S, uye kusangana nearuminiyamu acetate kunogona kuburitsa mvura yearuminiyamu nhema ine sarufa.

3, tembiricha yakakwira inogona kushandiswa kuvandudza mwero wekupararira kwemadhayi uye kuvandudza mwero wekupinda.
