Calcium carbide hmoov yog khaus thiab ua rau Ca (OH) 2 thaum kov kom tawm hws ntawm daim tawv nqaij, uas kub hnyiab ntawm daim tawv nqaij kom txog thaum nws ulcerates. Kev nqus pa tuaj yeem ua rau tib neeg ua pa. Hnav looj tsom iav dub, daim npog qhov ncauj thiab hnab looj tes thaum ua haujlwm. Cov roj hauv lub nruas yuav tsum tau tawm thaum tuav thiab ua ntej cia. Nws yog nruj me ntsis txwv tsis pub dov lub nruas, muab tso rau hauv qhov hnyav los yog sib tsoo nrog nws, txhawm rau tiv thaiv qhov tawg thiab tawg. Thaum lub pob tawg lawm, hluav taws xob vuam thiab soldering yog nruj me ntsis txwv tsis pub. Dej yog txwv tsis pub tua hluav taws, tsuas yog xuab zeb lossis carbon dioxide tuaj yeem siv los tua hluav taws, lossis qhuav sodium carbonate (soda tshauv hmoov) tuaj yeem siv los tua hluav taws. Thaum pom tias kiv taub hau, mob taub hau lossis ntuav, nws yuav tsum tau tsiv mus rau qhov chaw cua tshiab tam sim ntawd. Cov mob hnyav yuav tsum raug xa mus rau tsev kho mob kho mob. Ntim hauv cov nruas hlau nrog phab ntsa thickness tsis pub tsawg tshaj 1 hli, lOOkg lossis 200kg. Sab ntawm lub nruas yuav tsum tau cim nrog cov xim 'tsis txhob dej thiab hluav taws'.
Calcium carbide yuav tsum muab khaws cia rau hauv qhov chaw qhuav, txias, cua txias, thiab cov khoom siv hluav taws xob thiab cov kua qaub uas muaj zog yuav tsum raug cais tawm. Nws yog qhov zoo dua los khaws cia hauv qhov tshwj xeeb. nruj me ntsis tiv thaiv kev sib cuag nrog dej thiab noo noo. Lub thoob yuav tsum tau ntim cov roj acetylene ua ntej khaws cia. Lub sijhawm cia yog 6-12 hli.
