Cov Khoom Paub meej
HFC eps yog tsim los ntawm cov hlaws dub me me ntawm polystyrene (EPS) uas muaj tus neeg sawv cev tshuab, uas ua rau nws nthuav dav.Leasty chemical tsim cov khoom siv tshwj xeeb no, uas yog ua los ntawm cov tuam txhab ua npuas ncauj rau hauv cov ntaub ntawv insulating rau ntau hom kev siv sib txawv.
HFC eps yog qhov kev txhim kho tshiab ntawm cov rwb thaiv tsev classic eps thiab twb tau ua lub npe muaj zog txij li xyoo 2012, muab tag nrho cov txiaj ntsig ntawm tus thawj:
Qhov tseem ceeb ntawm graphite thiab cov hluav taws kub retardant eps
| Kev sib piv | Qib Graphite (HFC) | Dawb hluav taws kub retardant (F) |
| Qhov ntsuas hluav taws kub | B1 | B2 |
| Daim ntawv thov | Phab ntsa rwb thaiv tsev, Suab Rwb thaiv tsev, Fireproof | Phab ntsa rwb thaiv tsev, tub yees
Cia |
| Qhov ceev (g / l) | 14-35 : kuv | 12-30 |
| Coefficient ntawm thermal conductivity w / (mk) | ≤ 0.032 | ≤ 0.041 |
| Compressive zog (mpa) | ≥0.10 | ≥0.06 |
| Kev nqus dej | ≤ 2% | ≤ 2% |
| Oxygen Index | ≥30 | ≥30 |
HFC kev ua tau zoo dua hauv thermal conductivity
Kev txhim kho zoo heev ntawm cov rwb thaiv tsev tuaj yeem ua tiav nrog HFC, tshwj xeeb tshaj yog nrog cov khoom ntim tsawg heev. Daim duab qhia tau hais tias HFC insulating cov ntaub ntawv uas muaj qhov ntom ntom ntawm 15 kg / m³ piv txwv li ua tiav cov thermal conductivity ntawm 0.032 W / (m·K). Nyob rau hauv ib txwm EPS nrog tib qhov ntom ntom, cov thermal conductivity yog 0.037 W / (m·K).

APPLICATION
HFC eps yog nrog cov nplaim hluav taws zoo heev, ua haujlwm yooj yim yam tsis muaj plua plav thiab tsis muaj teeb meem rau daim tawv nqaij, dhau li ntawd, nws tseem tuaj yeem ua rau cov nyhuv rwb thaiv tsev zoo tib yam nrog cov tuab tuab dua li cov pa eps, txo tus nqi qis, ntxiv rau, nws tuaj yeem txuas ntxiv lub neej ntev lub tsev.
