CAS No. 1975-10-5 Difluoromethane Supplier. Cov yam ntxwv ntawm Difluoromethane
Tus lej CAS 1975-10-5 yog hais txog Difluoromethane, uas feem ntau hu ua HFC-32 (Hydrofluorocarbon). Qhov sib xyaw no yog siv dav hauv ntau yam kev lag luam, tshwj xeeb tshaj yog ua cov tub yees. Hauv qab no yog cov yam ntxwv ntawm Difluoromethane:
Cov yam ntxwv ntawm Difluoromethane (HFC-32):
Cov tshuaj formula: CH2F2
Cov tsos mob: tsis muaj xim tsis muaj roj lossis cov kua ntshiab, tsis muaj xim thaum compressed.
Kub taw tes: -51.7 ° C (-61.1 ° F)
Melting Point: -152.7 ° C (-242.9 ° F)
Qhov ceev: 1.44 kg / m³ ntawm 0 ° C (32 ° F) thiab 1 atm, kua ntom ntom ntawm 1250 kg / m³ ntawm 25 ° C (77 ° F) thiab 1 atm.
Solubility hauv dej: me ntsis soluble.
Vapor Siab: 1000 kPa ntawm 25 ° C (75 ° F)
Ozone Depletion Potential (ODP): 0 (tsis deplete ozone txheej)
Lub Ntiaj Teb Warming Potential (GWP): 100-xyoo GWP ntawm 2500 (qhov tseem ceeb ua rau lub ntiaj teb sov sov)
Kev Siv: Feem ntau yog siv los ua cov tub yees hauv cov tshuab cua txias, cov twj tso cua sov, thiab cov tub yees. Nws kuj tseem siv rau hauv hluav taws tua hluav taws, ua tus neeg sawv cev hauv kev ua npuas dej, thiab ua cov kuab tshuaj.
Cov ntaub ntawv kev nyab xeeb:
Difluoromethane tsis yog hluav taws kub tab sis tuaj yeem ua rau asphyxiation los ntawm kev tso pa oxygen hauv qhov chaw kaw.
Nws yog tshuaj lom nyob rau hauv siab concentration, cuam tshuam rau lub paj hlwb thiab tej zaum yuav ua rau lub plawv arrhythmia.
Kev raug rau qhov kub qis heev tuaj yeem ua rau frostbite.
