Muaj ntau lub zog, tseem hu ua cov tshuaj tiv thaiv ntawm ch3ch2ch, soluble} Nws yog cov ncauj lus qhia ntxaws ntxaws txog cov khoom siab siab muaj txiaj ntsig R290:
1. Cov Khoom Yooj Yim
Molecular hnyav: 44.0956
Melting taw tes: -187.6 degree
BLOILING NTAM: {{-42.1℃(qee cov ntaub ntawv-42.2 degree)
Quav: 1.83kg / m³ (roj)
Flash ntsiab lus: {-104 degree
Dej Solubility: me ntsis soluble
Qhov kub tseem ceeb: 96.67 degree
Qhov tseem ceeb: 4.24MPA
2.} lub ntsiab siv
Coolant: Muaj ntau yam siab purane r290 yog dav siv raws li lub txias txias, tshwj xeeb hauv cov tshuab cua txias, thiab cov tshuab cua txias {}}
Organic synthemes raw cov ntaub ntawv: hauv kev lag luam tshuaj, R290 kuj tseem siv tau los ua cov khoom siv hluav taws xob organic los koom nrog ntau yam kev tiv thaiv {}}
3.} ib puag ncig kev tiv thaiv cov yam ntxwv
Cov Khoom Siv Siab Rov Qab R290 yog ib qho kev cuam tshuam hydrocolarbon uas tsis muaj qhov cuam tshuam ntawm ozone txheej, thiab nws cov ntxhiab (ozone depletion muaj peev xwm) yog0.
Piv nrog HFC cov tshuaj, GWP (thoob ntiaj teb sov coefficient) tus nqi ntawm cov tsev cog khoom muaj txiaj ntsig, thiab nws tsis muaj qhov cuam tshuam rau lub tsev cog khoom muaj txiaj ntsig kuj tseem tsawg.
4. Kev ceev faj kev nyab xeeb
Siab pharity propane r290 yog cov nplaim taws thiab tawg, yog li kev tshwj xeeb yuav tsum tau them rau kev nyab xeeb thaum siv.
Thaum siv cov khoom noj muaj txiaj ntsig siab R290, cov khoom siv xau yuav tsum tau tawm kom ntau li ntau tau los tiv thaiv cov kua los ntawm kev sib txawv ntawm .
Yog tias cov kev sib txuas ntxiv tshwm sim, hluav taws kub tua hluav taws yuav tsum tau siv los tua hluav taws kub .
Cim npe nrov: Muaj ntau cov khoom siv siab muaj zog, Tuam Tshoj Cov Khoom Siv Purity Cov Khoom Siv, Cov Chaw Muag Khoom, Hoobkas
