Calcium Carbide 50-80 hli

 

Calcium carbide yog siv rau hauv: Acetylene tuaj yeem siv los ua ntau cov organic tebchaw, xws li roj hmab, resins, acetone, carbon dub, thiab lwm yam. Acetylene-oxygen nplaim yog siv rau vuam thiab txiav hlau.
2. Cua sov hmoov calcium carbide nrog nitrogen cov ntaub ntawv calcium cyanamide.
CaC2 + N2 → CaCN2 + C, ΔH=-296kJ/mol
CaCN2 yog ib qho tseem ceeb raw khoom rau CaCN2. Cov yaj los ntawm cua sov calcium cyanamide thiab saltpeter yog siv nyob rau hauv kub mining thiab non-ferrous hlau.
3. Calcium carbide tuaj yeem siv los tshem cov sulfur ntawm cov hlau.
4. Calcium carbide yog siv los ua polyvinyl chloride. Calcium carbide yog siv los ua polyvinyl chloride. Nws tsim acetylene thaum nws los rau hauv dej. Acetylene thiab hydrogen chloride yog sib xyaw ua ke los ua vinyl chloride monomer. Cov tshuaj tiv thaiv kab mob yog siv los ua polyvinyl chloride.
5. cov miners siv calcium carbide los ua teeb. Lawv muab tso rau hauv ib lub lauj kaub hlau thiab siv cov acetylene uas nws tsim los ua lub teeb.
