Calcium carbide yog cov khoom tseem ceeb ntawm calcium carbide, uas yog ib qho inorganic compound thiab dawb siv lead ua. Calcium carbide belongs rau qeb plaub ntawm cov khoom txaus ntshai, uas yog flammable thaum ntub dej.
Kev phom sij
Ua kom puas daim tawv nqaij, ua rau tawv nqaij khaus, o, "noog lub qhov muag" ulcer, thiab melanoderma. Cov tawv nqaij kub hnyiab tau tshwm sim los ntawm lub sij hawm ntev tsis kho ntawm qhov txhab thiab mob rwj. Cov neeg ua haujlwm raug tawm hws tsawg dua, enamel puas tsuaj, thiab muaj qhov tshwm sim ntau dua ntawm cov hniav caries.
Toxicological yam ntxwv thiab ib puag ncig tus cwj pwm ntawm calcium carbide
Kev puas tsuaj tawg: Cov khoom no yog nplaim taws thaum ntub.
Cov yam ntxwv muaj kev phom sij: nws tsis kub hnyiab thaum qhuav, thiab tuaj yeem tsim cov pa roj acetylene sai sai thaum muaj dej lossis noo noo. Thaum nws nce mus txog ib qho concentration hauv huab cua, kev puas tsuaj tawg tuaj yeem tshwm sim. Nws tuaj yeem cuam tshuam hnyav nrog cov kua qaub.
Combustion (decomposition) khoom: acetylene, carbon monoxide, carbon dioxide.
Kev pab thawj zaug
Kev sib cuag ntawm daim tawv nqaij: tshem cov khaub ncaws tsis huv tam sim ntawd thiab ntxuav nrog cov dej ntws loj li 15 feeb. Mus ntsib kws kho mob.
Kev sib cuag ntawm qhov muag: tam sim ntawd rub daim tawv muag thiab ntxuav lawv kom huv si nrog cov dej ntws loj lossis cov dej ntsev ib txwm tsawg li 15 feeb. Mus ntsib kws kho mob.
