1. R290 Cov ntaub ntawv yooj yim
Suav lub npe: propane
Cov mis mos molecular: C3H8
Molecular Luj: 44.10
Cov tsos thiab cov khoom: tsis muaj xim tsis muaj roj, tsis muaj ntxhiab tsw
Solubility: me ntsis soluble hauv dej, soluble hauv ether, ethanol
2. Lub cev thiab tshuaj muaj zog ntawm R290
Flash point (degree): -104
Explosion txwv feem pua (V/V): 9.5
Kev txwv qis ntawm qhov tawg feem pua (V / V): 2.1
Cov txheeb ze ntom ntom (cua =1): 1.56
Kub ntawm combustion (kJ/mol): 2217.8
Ignition kub (degree): 450 ~ 470
3. Kev siv nyab xeeb
Kev phom sij rau kev noj qab haus huv: yooj yim asphyxiation thiab tshuaj loog ua haujlwm. Luv luv tib neeg raug rau 1 feem pua propane tsis ua rau cov tsos mob; Concentrations qis dua 10 feem pua ua rau tsuas yog kiv taub hau; Tshuaj loog thiab tsis nco qab yuav tshwm sim thaum raug rau siab concentration. Cov concentration ntau heev tuaj yeem ua rau asphyxia. Flammable gas, uas tuaj yeem tsim cov khoom tawg thaum sib xyaw nrog huab cua thiab ua rau muaj kev phom sij ntawm kev sib tsoo thiab tawg thaum raug tshav kub thiab qhib nplaim taws.
Qhov tsis zoo ntawm R290 raws li lub tub yees yog qhov flammability ntawm R290 (compressor, condenser, evaporator, pipeline thiab lwm qhov chaw ntawm lub tub yees yuav ua rau cov pa taws ua haujlwm nruab nrab, thiab cov khoom siv hluav taws xob xws li kub tswj, compressor relay, teeb, defrost khawm yuav yog ignition source).
