Calcium carbide cov khoom lag luam yog grey tsaus, tan lossis dub grey, thiab cov uas muaj calcium carbide siab yog xiav ntshav. Nws thawj seem muaj gloss, thiab nws absorbs dej hauv cov roj hauv maub grey lossis grey dawb. Nws tuaj yeem ua cua sov. Qhov siab dua qhov purity, qhov zoo dua cov cua kub conduction. Nws tuaj yeem nqus dej hauv cov pa roj. Ntxiv dej los hloov ua acetylene thiab calcium hydroxide. Nws hloov mus rau hauv calcium cyanamide los ntawm cov tshuaj tiv thaiv nrog nitrogen. Calcium carbide yog ib qho ntawm cov khoom siv raw rau kev siv tshuaj lom neeg thiab kev lag luam chemical. Nws yog cov khoom siv tseem ceeb ntawm acetylene chemical plant. Acetylene ua los ntawm calcium carbide yog dav siv nyob rau hauv hlau vuam thiab txiav.
Txawm hais tias calcium carbide tsuas yog tshwm sim hauv cov ntaub ntawv kawm hauv tsev kawm theem siab, nws tau txais txiaj ntsig tshwj xeeb los ntawm cov neeg tsim cov lus nug vim nws muaj ntau haiv neeg ntawm cov qauv thiab cov khoom, ua rau nws yog ib qho ntawm cov chaw kub thiab cov hnub qub nto moo nyob rau hauv cov lus nug ntawm chemistry ntawm kev xeem nkag hauv tsev kawm qib siab. nyob rau hauv xyoo tas los no. Lub kaum sab xis ntawm nws cov lus nug tsis yog tsuas yog tshiab, tab sis kuj qhia tau qee yam tsis tu ncua lossis cov yam ntxwv. Calcium carbide hloov mus rau hauv acetylene thiab calcium hydroxide los ntawm solid-state thiab dej tshuaj cov tshuaj tiv thaiv, uas yog tib cov tshuaj tiv thaiv uas kawm nyob rau hauv nruab nrab tsev kawm ntawv los tsim acetylene los ntawm solid-state thiab dej tshuaj tiv thaiv.
Acetylene ignites los tsim cov nplaim taws, nrog rau cov pa luam yeeb loj. Calcium hydroxide yog ib yam khoom me ntsis soluble, uas yog ib qho yooj yim los tsim ib lub mis dawb ncua kev kawm ntawv. Cov tshuaj tiv thaiv ntawm calcium chloride khoom hauv lub xeev thiab dej yog cov tshuaj tiv thaiv muaj zog heev, thiab hloov pauv Ca (OH) 2 yog ib qho yooj yim los tsim cov tshuaj txhuam thiab thaiv cov qhov ntawm cov phaj yas, yog li cov tshuaj tiv thaiv no tsis tuaj yeem nqa tawm hauv. Lub tshuab hluav taws xob Qipu, tab sis tuaj yeem nqa tawm hauv cov khoom siv yooj yim uas tsis muaj lub phaj ntawm lub qhov ncauj.
Calcium carbide, cov ntsiab lus tseem ceeb ntawm calcium carbide, yog inorganic compound, dawb siv lead ua, cov khoom siv yog dub grey blocks, thiab seem yog xiav ntshav lossis grey tsaus. Nyob rau hauv cov ntaub ntawv ntawm dej, ib tug nruj tshuaj tiv thaiv tshwm sim tam sim ntawd, uas yog hloov dua siab tshiab rau hauv acetylene thiab muab tawm cua sov. Calcium carbide yog ib qho tseem ceeb ntawm cov khoom siv raw khoom, uas yog siv los tsim cov roj acetylene. Nws kuj yog siv nyob rau hauv tshuaj synthesis, oxyacetylene vuam, thiab lwm yam.
Khaws rau hauv ib lub tsev txias, qhuav nrog cua zoo. Tshem tawm qhov hluav taws kub thiab qhov chaw kub. Cov av noo yuav tsum khaws cia qis dua 75 feem pua. Lub pob yuav tsum raug kaw thiab tiv thaiv los ntawm ya raws. Nws yuav tsum tau muab cais los ntawm cov kua qaub, cawv, thiab lwm yam, thiab yuav tsum tsis txhob sib xyaw. Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau.
Cov cua sov rauv smelting txoj kev thiab cov pa cua sov txoj kev yog feem ntau siv nyob rau hauv kev lag luam. Cov cua sov rauv smelting txoj kev yog tso coke thiab calcium oxide (molecular formula Cao) nyob rau hauv lub qhov cub cua sov ntawm txog 2200 degree rau smelting thiab hloov mus rau hauv calcium carbide (molecular mis CaC2). Oxygen cua sov txoj kev: uas yog, smelting CaC2 (calcium carbide) nrog oxygen enriched oxygen cua sov txoj kev nyob rau hauv blast furnace, tau txais carbon los ntawm limestone, thiab kub hauv qab siab gas producer.
