Daim ntawv thov ntawm calcium carbide

Qhov tseem ceeb tshaj plaws ntawm cov calcium carbide yog nyob rau hauv kev tsim cov acetylene roj (c₂h₂). Thaum calcium carbide reacts nrog dej, nws generates acetylene, cov roj cua heev siv ntau hauv:

Hlau Vuam thiab Txiav: Acetylene, thaum hlawv nrog oxygen, ua rau cov nplaim taws nrog qhov kub ntawm dhau 3, {} degree, ua rau nws zoo tagnrho rau vuam thiab txiav cov hlau.

Kev Siv Hluav Taws Xob Hluav Taws Xob: Acetylene yog ib qho tseem ceeb rau ntau cov organic sib xyaw, suav nrog cov roj av vinyl, acetic acid, thiab roj hmab hluavtaws.

Keeb kwm, calcbium carbide tau siv nyob rau hauvcarbide teeb, uas tau siv dav hauv kev sib khuav thiab kev qaug zog. Cov teeb no tsim lub teeb los ntawm hlawv cov acetylene roj tsim tawm los ntawm cov tshuaj tiv thaiv ntawm cov dej calcium nrog dej.

Calcium carbide yog qee zaum siv hauv kev kho dej kom tshem tawm cov kab mob sulphur thiab lwm yam tsis txaus ntseeg. Nws tseem ua lub luag haujlwm hauv kev tsim cov calcium hydroxide, uas yog siv los nruab nrab acidic khib nyiab ntws.

Hauv qee thaj tsam, Calcium carbide yog siv rau artificialially ripen txiv hmab txiv ntoo. Nws tso acetylene roj, uas ua qog cov ntuj ripening tus neeg sawv cev ethylene. Txawm li cas los xij, qhov kev coj ua no muaj kev sib cav vim muaj peev xwm muaj kev pheej hmoo ntawm kev noj qab haus huv los ntawm cov tshuaj uas muaj kuab lom, thiab nws siv yog tswj hwm hauv ntau lub tebchaws.
