Calcium carbide yog lub zog muaj zog nrog cov qauv crystalline. Qhov kawg ntawm kev ntxoov ntxoo nyob ntawm qhov zoo ntawm cov ntaub ntawv raw thiab tuaj yeem sib txawv ntawm bluish rau ntshav, dub. Tsis tas li ntawd, ib qho tsis txaus siab tsis xav hnov ntawm qej yuav tshwm sim. Cov txheej txheem ntawm kev sib koom ua ke nrog dej thiab cov kev daws teeb meem ntawm cov roj av ntxhia lossis alkalis yog qhov tseem ceeb tshaj, raws li nws tsim ntau npaum li cas ntawm tshav kub.
Cov tshuaj tiv thaiv ntawm cov calcium carbide nrog dej yog sawv cev los ntawm cov hauv qab no: CAC {} {}, 2 + C2h2.
Raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv no, acetylene, ib qho kev tsis tau muaj txiaj ntsig nrog cov hlua khi, tseem tsim tau.
Cov tshuaj tiv thaiv ntawm decomposition ntawm calcium carbide los ntawm oxygen tshwm sim tsuas yog nyob rau hauv tus neeg kub ({} {{{+ 4 co2.
Raws li rau kev khaws cia thiab kev tsheb tsheb thauj ntawm calcium carbide, nws yuav tsum tau ntim rau hauv cov dej noo-pov thawj lossis tso tsheb hlau luam. Qhov no yog tsim nyog txhawm rau txhawm rau cais tawm hauv cov dej noo thiab tiv thaiv kev ua kom tiav. Kev saib xyuas yuav tsum tau ua ob qho tib si thaum ntim thiab tsis ntim. Nws tseem tsim nyog yuav tsum tsis txhob siv cov cuab yeej uas tsim cov zaub mov thaum lub sijhawm ua haujlwm.
Muab cov xwm txheej ntawm carbide nyob rau hauv tib neeg lub cev thiab tawv nqaij, nws yog ib qho tsim nyog los muab cov khoom tiv thaiv txhua tus nrog cov khoom tiv thaiv tsim nyog.
Kev thauj mus los yuav tsum nqa tawm tshwj xeeb los ntawm cov tsheb nrog lub cev kaw. Nws yuav tsum raug sau tseg tias kev xa khoom los ntawm huab cua yog nruj me ntsis txwv.
Nws yog ib qho tsim nyog los muab kev ua pa tawm hauv qhov chaw tsim hluav taws xob hauv cov khoom lag luam thiab txwv tsis pub cov khoom lag luam ua ke nrog lwm cov khoom lag luam.
