Thaumcalcium carbide (Cac₂)reacts nrogdej (h₂o),Kev siv tshuaj lom neeg tshwm sim uas tsim tawmAcetylene roj (C₂H₂)thiabCalcium hydroxide (CA (OH) ₂).
Cov kev sib npaug:
Cac2 {+2 h2 o → C2 + CA (Oh) 2
Yuav ua li cas nrog cov tshuaj tiv thaiv no?
Acetylene roj tsim:
AnrogCov roj tso tawm, uas yog siv hauv vuam, teeb pom kev zoo thiab tshuaj lom neeg.
Thaum igned,acetylene hlawv nrog lub ci ci, kub-nplaim hluav taws.
Tsim ntawm calcium hydroxide (hydrated txiv qaub):
Ib qho khoom lag luam zoo nkauj, nyob rau hauv kev sib cuag nrog uas nws tuaj yeem ua rauDaim tawv nqaij khaus thiab hlawv.
Tom qab cov tshuaj tiv thaiv, dawb, powdery lossis gel-zoo li residue tshwm sim.
Cov Neeg Kub Siab (Exothermic cov tshuaj tiv thaiv):
Cov tshuaj tiv thaiv tsimqho kub, ua rau cov txheej txheem feem ntaumuaj xwm txheejyog tias sab laug unchecked.
Cov chaw tiag tiag ntawm daim ntawv thov ntawm cov tshuaj no:
Zus tau tej cov acetyleneRau vuam thiab tshuaj schtesis.
Carbide teeb(keeb kwm siv nyob rau hauv tsuas thiab speliingology).
Txiv hmab txiv ntoo ripening(Txawm hais tias kev txom nyem vim muaj peev xwm impurities).
Cov kev ceev faj:
Zam kev sib cuag ncaj qhaNrog calcium carbide li noo noo (suav nrog hws) tuaj yeem ua rau muaj kev tawm tsam.
Khaws rau hauv qhov chaw qhuavkom tsis txhob muaj roj tsis zoo.
Ua haujlwm hauv qhov chaw muaj cua zooTxhawm rau zam kev tsim cov acetylene, uas tuaj yeem ua rau tawg.
