Calcium carbide yog txwv tsis pub muaj kev pheej hmoo txaus ntshai nrog nws impurities. Industrial-qib calcium carbide feem ntau muaj cov teeb meem arsenic thiab phosphorus, thiab raws li cov teeb meem kev noj qab haus huv (xws li cov tsos mob ua pa (suav nrog kev ua pa, thiab ua pa tawm).
Ib qho ntxiv, kev siv cov calcium carbide rau cov txiv hmab txiv ntoo siav yog tsis nyab xeeb. Cov tshuaj acetylene roj nws tsim cov kev ua tau zoo ib yam li cov txiv hmab txiv ntoo ripenene, tab sis tshwm sim hauv cov txiv hmab txiv ntoo ripening-txiv hmab txiv ntoo yuav tshwm sim rau sab nraud thaum tseem tshuav nyob sab hauv. Cov txheej txheem no tuaj yeem hloov cov tsw thiab kev ua kom muaj txiv hmab txiv ntoo txeej uas tsis muaj qhov qab zib thiab ua rau muaj kev pheej hmoo zoo vim kev muaj teeb meem kev muaj teeb meem.
Tsis tas li ntawd, calsermore, calcium carbide yog cov nplaim taws thiab tuaj yeem yog cov khoom tawg tau thaum nws rov qab los nrog dej, ua tshuaj acetylene roj. Tsis raug cai cia rau hauv cov chaw muaj peev xwm tsim kev phom sij hluav taws.
