Kodi Mumadziwa Chiyani Zokhudza Utoto Wa Sulfure(1)?

Utoto wa sulfure ndi utoto womwe umasungunuka mu alkali sulphur.Amagwiritsidwa ntchito kwambiri podaya ulusi wa thonje ndipo amathanso kugwiritsidwa ntchito ngati nsalu zophatikizika za thonje/vitamini.Mtengo wake ndi wochepa, utoto nthawi zambiri umatha kutsuka komanso mwachangu, koma mtunduwo siwowala mokwanira.Ambiri ntchito mitundu ndiSulfur Blue 7,Sulfur Red 14 Sulfur Black Bluishandzina zotero.Mitundu ya sulfure yosungunuka ilipo tsopano.Utoto wopangidwa ndi vulcanization reaction ya amines, phenols, kapena nitro compounds of onunkhira hydrocarbons okhala ndi sulfure kapena sodium polysulphur,

mwapadera

Utoto wa sulfure susungunuka m'madzi, ndipo sulfure ya sodium kapena zinthu zina zochepetsera zimagwiritsidwa ntchito kuchepetsa utotowo kukhala ma leucochromes osungunuka.Imalumikizana ndi CHIKWANGWANI ndipo imadetsa CHIKWANGWANI, kenako imabwezeretsanso kusasungunuka kwake ndi makutidwe ndi okosijeni ndi kukonza pa ulusi.Chifukwa chake utoto wa sulfure ulinso utoto wa VAT.Utoto wopangidwa ndi vulcanized ukhoza kugwiritsidwa ntchito popaka thonje, hemp, viscose ndi ulusi wina, kupanga kwake kumakhala kosavuta, kotsika mtengo, kumatha kupakidwa utoto wa monochrome, komanso kutha kukhala mtundu wosakanikirana, kuthamanga kwabwino kwa kuwala kwa dzuwa, kusayenda bwino kuvala.Chromatographic kupanda ofiira, wofiirira, mdima mtundu, oyenera utoto wamphamvu mtundu.

mtundu

Kutengera mitundu yosiyanasiyana ya utoto, utoto wa sulfure ukhoza kugawidwa kukhala utoto wa sulfure wokhala ndi sodium sulfure monga chochepetsera ndi utoto wa VAT wa sulfure wokhala ndi sodium disulfite ngati chochepetsera.Kuti agwiritse ntchito mosavuta, gulu la sulfonic acid limalowetsedwa ndi sodium metabisulfite kapena sodium formaldehyde bisulfite (dzina lodziwika) kuti apeze utoto wa sulfure wosungunuka m'madzi, womwe ungagwiritsidwe ntchito mwachindunji ku utoto popanda kuchepetsa wothandizila.

(1) utoto wa sulfure wogwiritsa ntchito sodium sulfure monga chochepetsera;

(2) utoto wochepetsera sulfure (wotchedwanso Haichang dyes) wokhala ndi ufa wa inshuwaransi ngati wothandizira kuchepetsa;

(3) Utoto wa sulfure wamadzimadzi ndi mtundu watsopano wa utoto wa sulfure wopangidwa kuti upangidwe mosavuta.

Kugwiritsiridwa ntchito kwa utoto woterewu ndi kofanana ndi utoto wosungunuka wa VAT, womwe ukhoza kuchepetsedwa mwachindunji ndi madzi molingana ndi kasinthidwe, popanda kuwonjezera zochepetsera, ndipo sulfure ina ya sodium iyenera kuwonjezeredwa pamene mbali yokha ya mtundu ndi yowala.Mtundu uwu wa utoto chromatography ndi yotakata, pali ofiira owala, wofiirira bulauni, Hu wobiriwira.

Kubala

Pali njira ziwiri zopangira utoto wa sulfure m'mafakitale: ① njira yophika, ma amine onunkhira, ma phenols kapena nitro matter ndi sulfure kapena sodium polysulphur pakuphika kutentha kwambiri, kuti apange utoto wachikasu, lalanje, wofiirira.② Njira yowiritsa, ma amine, phenols kapena nayitrogeni wamafuta onunkhira a hydrocarbon ndi sodium polysulphur amatenthedwa ndikuwotchedwa m'madzi kapena zosungunulira za organic kuti apeze utoto wakuda, buluu ndi wobiriwira.

chilengedwe

1, ofanana ndi utoto wachindunji

(1) mchere ukhoza kugwiritsidwa ntchito kulimbikitsa utoto.

(2), cationic mtundu kukonza wothandizila ndi zitsulo mchere mtundu kukonza wothandizila kusintha fastness.

2, yofanana ndi utoto wa VAT

(1), utoto uyenera kuchepetsedwa kukhala leachite ndi chochepetsera kuti udaye ulusi ndi oxidize pa ulusi.M'malo mochepetsera mphamvu, sodium sulfure ndi yofooka yochepetsera.Komabe, katundu wachindunji wa leaches ku ulusi atachepetsedwa ndi wotsika kuposa wa utoto wa VAT, ndipo chizolowezi chophatikiza utoto ndichokulirapo.

(2) Zomwe zimachitika ndi asidi zimatha kutulutsa mpweya wa H2S, ndipo zomwe zimachitika ndi aluminiyamu acetate zimatha kutulutsa mpweya wakuda wa sulfure.

3, kutentha kwapamwamba kungagwiritsidwe ntchito kupititsa patsogolo kufalikira kwa utoto ndikuwongolera kuchuluka kwa malowedwe.
