Cov ntawv thov ntawm calcium carbide (Cac₂)
Calcium carbide, ib qho tshuaj xyaw nrog cov tshuaj crecul, yog siv dav hauv ntau cov txheej txheem kev lag luam thiab tshuaj lom neeg vim nws lub peev xwm los tsim cov roj acetylene (c₂₂) thaum cov tshuaj tiv thaiv dej. Daim ntawv thov tseem ceeb muaj cov chaw muaj:
1. Acetylene ntau lawm
Calcium carbide sweetacts nrog dej los ua cov roj acetylene roj, muaj roj me me rau oxy-acetylene vuam thiab txiav cov hlau ua haujlwm.
Acetylene tseem siv tshuaj lom hluavtaws (piv txwv li, tsim cov plastics, cov kuab tshuaj zoo li roj hmab vyloride, thiab roj hluavtaws (hluavtaws hluavtaws).
2. Tshuaj Kev Lag Luam
Cov khoom siv raw rau kev tsim cov khoom lag luam calcium cyanamide (ib tug chiv thiab nitrogen fixation tus neeg sawv cev).
Siv hauv kev tsim cov vinyl chloride monomer (VCM), ib qho prefursor rau polyvinyl chloride (PVC).
Qhov tseem ceeb hauv nruab nrab hauv cov synthic (piv txwv li, rau cov hluavtaws hluavtaws thiab acetic acid).
3. Steelmaking & Metallurgy
Ua raws li tus neeg sawv cev desulfurizing kom tshem tawm cov leej faj los ntawm hlau thiab hlau.
Qee zaum siv los ua cov roj roj hauv cov txheej txheem metallurgical.
