Ntau Lawm Calcium Carbide
Kev lag luam kev lag luam, calcium carbide yog tsim nyob rau hauv lub rauv hluav taws xob rauv los ntawm kev sib xyaw ntawm cov txiv qaub thiab coke ntawm qhov kub txog li 2.200 degree (3.990 degree (3.990 degree (3.990 degree (3.990 degree f). Hauv nws daim ntawv ntshiab nws yog xim tsis muaj xim crystalline khoom nrog lub pob zeb zoo li cov qauv ntawm chav sov. Qhov no yog endothermic cov tshuaj tiv thaiv yuav tsum tau 110 calories (460 KJ) ib mole thiab kub los tsav tawm cov pa roj carbon monoxide. Cov txheej txheem tsis tau hloov txij li nws tsim muaj nyob hauv 1892:
CaO + 3 C → CC 2 + CO
Calcium carbide reacts nrog dej los ua acetylene thiab calcium hydroxide.

Q: Cov roj muaj txiaj ntsig zoo li cas?
A: Feem ntau, cov roj tawm los ntawm cov particle loj {{mm, {mm,} mm yog 295L / kg.
Q: Lub sijhawm khoom xa tuaj yog dab tsi?
A: Nws yog feem ntau tsis pub dhau 20 hnub tom qab tau txais qhov tso nyiaj lossis thawj L / c.
Q: Kev siv thawj zaug ntawm cov calcium carbide yog dab tsi?
A: Calcium carbide feem ntau siv hauv ob qho chaw tseem ceeb: kev tsim cov tshuaj acetylene roj thiab hluav taws xob organic. Nws yog qhov tseem ceeb ntawm cov acetylene roj, uas pom pom dav cov ntawv thov hauv vuam, txiav, teeb pom kev zoo, thiab lwm yam. Tsis tas li ntawd, calcium carbide pabcuam ua cov khoom siv raw rau cov khoom siv los ntawm cov organic los tsim cov tshuaj zoo li vinyl chloride thiab hluavtaws resins.
Q: Dab tsi yog qee qhov siv ntawm calcium carbide?
A: Ntxiv rau nws thawj cov kev siv, calcium carbide tuaj yeem siv rau hauv oxyacetylene vuam, thiab raws li tus neeg sawv cev rascium rau txo cov oxide emissions los ntawm kev sib txuas.
