Thaumcalcium carbide (Cac₂)reacts nrogDej (h₂o), cov tshuaj lom neeg siv tshuaj tiv thaiv tshwm sim ua rau kev tsimAcetylene roj (C₂H₂)ThiabCalcium Hydroxide (Ca (Oh) ₂)Cov.
Cov kev sib npaug:
Cac2 {+2 h2 o → C2 + CA (Oh) 2
Yuav muaj dab tsi tshwm sim thaum lub sijhawm no?
Tsim cov tshuaj acetylene roj:
Sawv tawmnrogCov roj uas siv hauv vuam, teeb pom kev zoo thiab tshuaj lom neeg.
Thaum igned, acetylene hlawvCi Kub Kub KubCov.
Tsim ntawm calcium hydroxide (slaked txiv qaub):
Cov Khoom Alkaline Alkaline, thaum muaj kev sib cuag nrog uas yuav ua rauDaim tawv nqaij khaus thiab hlawvCov.
Tom qab cov tshuaj tiv thaiv, dawb, powdery lossis gel-zoo li residue tshwm sim.
Thaum tshav kub tso tawm (exothermic cov tshuaj tiv thaiv):
Cov kev tawm tsamsov, uas ua rau cov txheej txheem feem ntaumuaj xwm txheej, yog tias nws tsis raug tswj hwm.
Cov Kev Siv Lub Ntiaj Teb Tiag Ntawm Cov Kev Tiv Thaiv no:
Acetylene ntau lawmRau vuam thiab tshuaj schtesis.
Carbide teeb(keeb kwm siv nyob rau hauv tsuas thiab speliingology).
Txiv hmab txiv ntoo ripening(Txawm hais tias tsis muaj kev nyab xeeb vim -} Cov impurities).
Cov kev ceev faj:
Zam kev sib cuag ncaj qhaNrog calcium carbide, raws li ya raws (suav nrog hws) tuaj yeem ua rau muaj kev tiv thaiv.
Khaws rau hauv qhov chaw qhuavkom tsis txhob muaj cov roj tsis sib haum.
Ua haujlwm hauv qhov chaw muaj cua zooTxhawm rau zam dhau kev tsim cov acetylene, uas tuaj yeem ua rau tawg.
