Zinthu Zomwe Muyenera Kudziwa Zokhudza Sulphur Black

Maonekedwe awakuda wa sulfurendi kristalo wakuda wosweka, ndipo pamwamba pa kristalo pali kuwala kosiyana (kusintha ndi kusintha kwa mphamvu). Yankho lamadzi ndi madzi akuda, ndipo sulfure wakuda umafunika kusungunuka pogwiritsa ntchito yankho la sodium sulfide.

Utoto wakuda wa Sulfur ndi utoto wopangidwa kuchokera ku banja la utoto wa sulfure. Umagwiritsidwa ntchito kwambiri mumakampani opanga nsalu popaka utoto wa thonje chifukwa umapereka mtundu wakuda kwambiri. Utoto wakuda wa Sulfide umadziwika chifukwa cha kusala kwake bwino kwa utoto, zomwe zikutanthauza kuti sudzazimiririka ngakhale utatsukidwa mobwerezabwereza kapena kutenthedwa ndi dzuwa. Ndi wotsika mtengo komanso umapezeka kwambiri pamsika.

Njira yotulutsira sulfure wakuda imachokera ku 2,4-dinitrochlorobenzene, yomwe imathiridwa madzi pansi pa mikhalidwe ya alkaline kuti ipeze mchere wa 2,4-dinitrophenol sodium, womwe umawonjezeredwa ku yankho la sodium polysulfide kuti ipangitse kuti iwonongeke. Pambuyo pa okosijeni, kusefedwa, chinthu chomalizidwa chimauma.

Sulphur wakuda amagwiritsidwa ntchito kwambiri popaka utoto thonje, hemp, viscose ndi nsalu zake zosakanikirana. Nsalu zambiri za denim (zakuda) zomwe zimakonda kwambiri kunyumba ndi kunja zimapangidwa ndi ulusi wakuda wolukidwa ndi ulusi woyera. Sulphur wakuda uli ndi ma bond ambiri a disulfide pambuyo poti wachepetsedwa ndi sodium sulfide, ndipo n'zosavuta kusungunuka kuti uchepetse mphamvu ya nsalu zopakidwa utoto, kutanthauza kusweka. Kuti mupewe kuwonongeka kwa kusweka, muyenera kulabadira mfundo izi:

1. Yang'anirani kuchuluka kwa sulfure wakuda. Kuchuluka kwa sulfure wakuda, kuwonongeka kwa brittle kumatha kuchitika.
2、Tsukani bwino kuti muchepetse mtundu woyandama pa katundu.
3. Gwiritsani ntchito zowonjezera za Taikoo Oil kuti mupewe kusweka.
4、Kupukuta ndi madzi abwino musanaunike utoto. Ulusi wothira madzi oyesera ukaunika utoto uli ndi kukhuthala kwabwino kuposa lye.
5、Umitsani pakapita nthawi mutapaka utoto kuti muchepetse kuchuluka kwa zinthu zothandizira kuwononga chifukwa cha kunyowa.
