Calcium Carbide 50-80mm Nqe lus piav qhia
Kev siv cov calcium carbide
1. Acetylene tsim los ntawm cov tshuaj tiv thaiv ntawm calcium carbide thiab dej tuaj yeem siv los tsim ntau cov organic sib txuas, xws li roj hmab hluavtaws, cov khoom siv dag zog, acetone, ketene, carbon dub, thiab lwm yam. Acetylene-oxygen nplaim kuj yog siv dav rau vuam thiab txiav. hlau.
2. Thaum hmoov calcium carbide yog rhuab nrog nitrogen, calcium cyanamide yog tsim:
CaC2 + N2 → CaCN2 + C , ΔH=-296kJ/mol
Calcium cyanamide yog ib qho tseem ceeb raw khoom rau kev npaj ntawm calcium cyanamide. Cov yaj tsim los ntawm cua sov calcium cyanamide thiab saltpeter yog siv nyob rau hauv kub mining thiab non-ferrous hlau kev lag luam.
3. Calcium carbide nws tus kheej tuaj yeem siv los ua desulfurizer hauv kev lag luam steel.
4. Hauv kev tsim cov polyvinyl chloride (PVC), calcium carbide yog siv los tsim polyvinyl chloride. Calcium carbide (calcium carbide CaC2) yog siv los tsim polyvinyl chloride. Thaum nws los rau hauv dej, nws tsim acetylene (C2H2). Acetylene tau ua ke nrog hydrogen chloride (HCl) los tsim cov yas chloride monomer (CH2=CHCl). Cov tshuaj tiv thaiv kab mob yog siv los tsim polyvinyl chloride-[CH2-CHCI]n-los ntawm cov tshuaj tiv thaiv polymerization.
5. Nyob rau hauv ancient sij hawm, cov miners siv calcium carbide los ua calcium carbide teeb los ntawm muab tso rau hauv ib lub kaus poom hlau thiab siv cov generated acetylene (C2H2) los ua cov teeb.
