Calcium Carbide
Khoom Description
Calcium carbide yog ib qho inorganic compound nrog cov tshuaj formula CaC2 thiab molecular hnyav ntawm 64.099. Nws cov tsos yog tus cwj pwm los ntawm cov hmoov dawb crystalline hmoov. Cov tsos ntawm cov khoom lag luam calcium acetylide yog grey-dub pob nrog ntshav lossis grey hla ntu. Nws muaj ib tug melting point ntawm 447 degree, lub boiling point ntawm 2300 degree, thiab ib tug flash point ntawm -17.8 degree. Nws reacts hnyav thaum nws ntsib dej los tsim acetylene thiab tso cua sov.

Cov txheej txheem tsim khoom
Tom qab cov txiv qaub hlawv yog crushed thiab tshuaj ntsuam, nws raug xa mus rau lub txiv qaub silo cia kom txog thaum siv. Cov txiv qaub thiab coke uas ua tau raws li cov kev xav tau ntawm calcium carbide ntau lawm yog batched raws li qhov piv txwv, thiab tus nqi raug xa mus rau sab saum toj silo ntawm lub cub hluav taws xob nrog lub thoob of elevator.
Tus nqi yog ntxiv rau lub cub hluav taws xob los ntawm cov khoom siv raj. Tus nqi dhau los ntawm electrode arc ncoo thiab them rau hauv lub cub hluav taws xob. Cov tshuaj tiv thaiv tshav kub ua rau cov calcium carbide.
Nws raug tshem tawm ntawm lub qhov cub thaum lub sijhawm tsis tu ncua thiab muab tso rau hauv lub lauj kaub calcium acetylide. Tom qab txias, nws tau tawg rau hauv qee qhov yuav tsum tau muaj qhov loj me me kom tau txais cov calcium carbides tiav.
Cov khoom siv
1. Acetylene tsim los ntawm cov tshuaj tiv thaiv ntawm calcium carbide thiab dej tuaj yeem ua ke ntau cov organic sib txuas, xws li: roj hmab hluavtaws, cov khoom siv dag zog, acetone, ketene, carbon dub, thiab lwm yam.; tib lub sijhawm, acetylene-oxygen nplaim yog dav siv rau hlau vuam thiab txiav. (carbide) yog ib qho tseem ceeb ntawm cov khoom siv raw khoom thiab feem ntau yog siv los tsim cov roj acetylene. Kuj tseem siv rau hauv cov organic synthesis, oxy-alkylene vuam, thiab lwm yam.
2. Thaum hmoov calcium acetylide thiab nitrogen yog rhuab, cov tshuaj tiv thaiv tsim calcium cyanamide, uas yog, txiv qaub nitrogen. Lub cyanide yaj tsim los ntawm cov tshuaj tiv thaiv ntawm rhuab txiv qaub nitrogen thiab rooj ntsev yog siv nyob rau hauv kub mining thiab non-ferrous hlau industries.
3. Carbide nws tus kheej tuaj yeem siv los ua desulfurizer hauv kev lag luam steel.
4. Thaum hmoov reacts nrog N2, calcium cyanamide, uas yog, txiv qaub nitrogen, yuav raug tsim: txiv qaub nitrogen yog ib qho tseem ceeb raw khoom rau kev npaj cyanamide amides. Cov tshuaj ua los ntawm cov tshuaj tiv thaiv ntawm rhuab txiv qaub nitrogen nrog ntsev yog siv nyob rau hauv lub kub mining thiab non-ferrous hlau industries.
