Calcium carbide tshuaj lub npe rau calcium carbide, molecular mis rau CaC2, cov tsos ntawm grey, xim av, dub los yog xim av lumpy khoom, yog lub hauv paus raw khoom ntawm organic synthetic chemical kev lag luam, kev siv ntawm calcium carbide raws li raw cov ntaub ntawv yuav tsum tau synthesized ib tug series. ntawm cov organic tebchaw, rau kev lag luam, kev ua liaj ua teb, tshuaj los muab cov ntaub ntawv raw. Nws lub ntsiab siv yog:
(1) calcium carbide thiab dej cov tshuaj tiv thaiv tsim los ntawm acetylene tuaj yeem ua ke rau hauv ntau cov organic tebchaw, xws li: roj hmab hluavtaws, hluavtaws resins, acetone, ketene, carbon dub, thiab lwm yam.; Nyob rau tib lub sijhawm, acetylene cov nplaim hluav taws yog siv dav hauv cov hlau vuam thiab txiav.
(2) cua sov hmoov calcium carbide thiab nitrogen, cov tshuaj tiv thaiv generates calcium cyanamide, piv txwv li, txiv qaub nitrogen, cua sov txiv qaub nitrogen thiab ntsev cov tshuaj tiv thaiv generated los ntawm cyanide yaj siv rau kub mining thiab non-ferrous hlau kev lag luam.
(3) Calcium carbide nws tus kheej tuaj yeem siv los ua tus neeg sawv cev desulphurizing hauv kev lag luam hlau thiab hlau.
