Kev npaj ntawm ammonium thiocyanate chemical mis:
Lub siab synthesis cov tshuaj ntawm carbon disulfide thiab ammonia hydrosulfide, uas yog tom qab ntawd decomposed rau hauv hydrogen sulfide los ntawm desulfurizes los ntawm desulfurization los ntawm kev ua haujlwm thiab evaporation. Cov kev daws teeb meem yog kev lim dej thiab sib cais kom tau txais cov khoom. Lwm txoj kev xaiv, cov leej fajrfur tuaj yeem raug cuam tshuam nrog sodium cyanide los tsim sodium thiocyanate, uas tuaj yeem yog decomposed nrog ammonium chloride los tsim ammonium hydrosulfite.

Lub Hom Phiaj ntawm Ammonium thiocyanate siv:
Nws siv hauv kev lag luam hlau los npaj cov neeg sawv cev ua kom cov neeg sawv cev.
Nws siv ua tus neeg sawv cev dub hauv Nickel plating electrolytes thiab rau kev txiav txim siab hlau thiab nyiaj ions hauv cov electrolytes hauv kev ntsuas tshuaj anchistral.
Thawj-pab ntsuas:
Kev Tiv Thaiv Daim tawv: Tshem cov khaub ncaws tsis huv thiab yaug nrog dej ntau.
Kev Tiv Thaiv Qhov Muag: Nqa daim tawv muag thiab yaug nrog dej ntws lossis dej qab ntsev. Nrhiav kev kho mob.
Inhalation: tshem tawm los ntawm qhov chaw rau ib qho chaw nrog huab cua ntshiab. Yog tias ua pa nyuaj, tswj cov pa oxygen. Nrhiav kev kho mob.
Kev noj haus: Haus dej sov thiab ua kom ntuav. Plab lub cev thiab tso kua dej. Nrhiav kev kho mob.
Kev Tiv Thaiv Hluav Taws Kub
Cov yam ntxwv muaj kev phom sij: tsis muaj kuab. Thermal decompose tso tawm cov roj toxic xws li nitrogen thiab sulphur oxides.
Kev tsim txom cov khoom lag luam: carbon monoxide, nitrogen oxides, leej faj oxides.
Hluav Taws Kub Extinguishing Txoj Kev: Cov neeg tua hluav taws yuav tsum hnav cov khaub ncaws hluav taws tag nrho thiab cov khaub ncaws roj tiv thaiv thiab tua hluav taws hauv cov kev taw qhia. Thaum tua hluav taws, sim txav lub khob ntawm qhov chaw tua hluav taws mus rau qhov chaw qhib kom ntau li ntau tau.
