kugwiritsa ntchito
ogwiritsidwa ntchito pakugulitsa migodi ngati inrobitor, ochiritsa, kuchotsa othandizira
Kugwiritsidwa ntchito popanga zachilengedwe zapakatikati ndikukonzekera kwa ma sulfure owonjezera matomwini.
Ogwiritsidwa ntchito popanga mafakitale monga kusungunuka, monga kusanja komanso ngati wothandizira
ogwiritsidwa ntchito mu plp ndi mapepala.
amagwiritsidwa ntchito mankhwala ochizira madzi ngati wothandizila kwa oxygen.
Zina zogwiritsidwa ntchito
Mu makampani ojambula kuti muteteze mayankho ogwira ntchito ku makutidwe.
♦ Amagwiritsidwa ntchito popanga mankhwala a mphira ndi mankhwala ena mankhwala.
♦ Zimagwiritsidwa ntchito mu ntchito zina zimaphatikizapo kulowerera kwa ore, kuchira kwamafuta, chakudya chosungira, kukonza utoto, komanso zowonongeka.
Kusamalira ndi Kusunga
A.precations popititsa patsogolo
1.Kugwiritsa ntchito pamalo abwino.
2.War zovomerezeka zoteteza.
3.Kakugwirizana ndi khungu ndi maso.
4.ke kutali ndi kutentha / spark / malo otseguka / otentha.
5.Kodi njira zachinyengo zotsutsana ndi zomwe zimasungidwa.
B.precaces osungira
1.Kula ndi zotsekeka mwamphamvu.
2.Kudzaza m'malo owuma, ozizira komanso abwino.
3.Kuchotsa pamoto / spark / zotseguka / malo otentha.
4. Sungani kutali ndi zida zosagwirizana ndi ziweto zazakudya.
Mankhwala ndi mankhwala a sodium hydholide (nahs)
1. Katundu wathupi
Maonekedwe: Sodium Hydrosulfide nthawi zambiri imakhala yoyera kapena yoyera yachikasu. Ingakhalenso wopanda utoto wokhala wachikasu, wonyezimira wokhala ndi fungo la hydrogen sulfide.
Malo osungunuka: malo osungunuka a sonhyrous sodium hydhilfide ndi 350 ° C; Malo osungunuka a hydrate ndi otsika, pa 52-54 ° C. Komabe, deta ina ikuwonetsa kuti malo osungunuka a sodium hydhil ali 55 ° C.
Kuchulukitsa: Tsoka la sodium hydhilfide ndi 1.79 g / cm³, kapena 1790 kg / M³.
Solubility: Sodium Hydrosul amasungunuka mosavuta m'madzi ndi mowa, ndipo mankhwala ake am'madzi ndi alkaline. Malinga ndi deta ina, kusungunuka kwa sodium hydhilfide m'madzi ndi 620g / l pa 20 ° C.
2. Mankhwala
Acidity ndi achimwemwe: The Aquaous yankho la sodium hydhil ndi alkaline.
Kuchita ndi Acid: Sodium Hydrosulfide amatulutsa hydrogen sulfide gasi ikakumana ndi asidi. Equation yopanga ndi: Nahs + H + → H2s ↑. Kodi ndi ndani?
Kuchita ndi sulufule: sodium hydrosul atha kuchitira ndi sulufure kuti apange polysulfides, equation yomwe ili: 2nah + 4s → na2s → na2s → Na2Sh
Kuthekera: sodium hydhilfide ndi komwe kumagwiritsidwa ntchito nthawi zambiri mankhwala omwe amatha kupezekanso ndi omwe amapezeka ndi oxidant ambiri.
3. Katundu wina
Kukhazikika: sodium hydrosulfide ndi gawo lokhazikika, koma ndi hygroscopic. Nthawi yomweyo, imakhalanso yolimba ndipo imatha kuyatsa mlengalenga.
Kuopsa: sodium hydhilfide ndi poizoni pamlingo wina komanso wovulaza thupi laumunthu ndi chilengedwe. Chifukwa chake, chidwi chapadera chikuyenera kulipiridwa ku chitetezo cha chitetezo pakugwiritsa ntchito ndikusunga.
Pakadali pano, kampaniyo ikuwonjezera misika yakunja ndi mawonekedwe apadziko lonse lapansi.
M'zaka zitatu zotsatira, ndife odzipereka kukhala amodzi mwa mabizinesi khumi opita kunja kwa mayi tsiku ndi tsiku, akupanga zinthu zapamwamba komanso kukwaniritsa zopambana ndi makasitomala ambiri.
Kupakila
Lembani imodzi: 25 kg matumba (pewani mvula, chonyowa ndi dzuwa liwiro paulendo.)
Lembani ziwiri: 900/1000 makilogalamu (pewani mvula, chonyowa ndi dzuwa liwiro paulendo.)
