Yam ntxwv
Calcium carbide tuaj yeem nqus dej noo hauv huab cua. Nws tuaj yeem ua hluav taws xob, thiab qhov siab dua qhov purity, nws yooj yim dua los ua hluav taws xob. Thaum ntsib dej lossis chav dej, cov pa hluav taws xob thiab tawg acetylene (feem ntau hu ua carbide gas) tuaj yeem tshwm sim. Cov pa roj no tuaj yeem ignite thaum ntsib cov sparks thiab tseem tuaj yeem ignited los ntawm cov tshuaj tiv thaiv kub. Cov roj acetylene thiab qee cov ntsev hlau hnyav tuaj yeem tawm mus rau hauv qhov sib xyaw ua kom tawg siab. Calcium carbide feem ntau muaj cov impurities xws li phosphorus thiab sulfur, thiab reacts nrog dej kom tso pa roj xws li phosphine thiab hydrogen sulfide. Thaum cov ntsiab lus ntawm phosphine tshaj 0.08 feem pua thiab cov ntsiab lus ntawm hydrogen sulfide tshaj 0.15 feem pua, nws yog ib qho yooj yim ua rau spontaneous combustion thiab tawg. Nws cov hmoov ua rau lub qhov muag thiab cov kab mob ua pa, thiab tuaj yeem ua rau tawv nqaij kub hnyiab.
Cia
Nws yuav tsum tau muab khaws cia rau hauv qhov chaw txias, qhov cua, thiab qhov chaw qhuav, qhov chaw tsis tso dej tawm. Nws yuav tsum tau ua tib zoo saib xyuas thaum thauj khoom thiab tshem tawm, thiab cov tsheb thauj mus los yuav tsum muaj cov khoom siv los nag thiab dej tsis zoo, kom deb ntawm cov hlau, tooj liab, thiab ntsev. Thaum lub sijhawm thauj mus los, nws yuav tsum tau thauj khoom tom qab thiab tshem tawm ua ntej. Nws yog txwv tsis pub thauj khoom ntawm lub lawj kom tsis txhob raug tshav ntuj. Nws yog txwv tsis pub siv dej thiab ua npuas ncauj thaum tua hluav taws. Cov hmoov qhuav thiab cov xuab zeb qhuav tuaj yeem siv tau. Tom qab muaj tshuaj lom, tib neeg yuav tsum tau txav mus rau huab cua ntshiab tam sim ntawd thiab muab cov pa oxygen uas muaj 5 feem pua ntawm cov pa roj carbon dioxide los pab ua pa.
