FAQ:
1. Yog vim li casAirgel rwb thaiv tsev pamua haujlwm zoo dua li cov ntaub ntawv rwb thaiv tsev ib txwm?
Its nano-aerogel structure (porosity >80%) blocks tshav kub conduction thiab hluav taws xob, nrog thermal conductivity tsawg li 0.015 W / (m·K) (25 degree), 1/3 ntawm pob zeb ntaub plaub. Ultra- qauv tsim (1–20mm) ua tiav tib lub rwb thaiv tsev li 3-5 npaug ntawm cov khoom siv tsoos tuab.
2: Yuav ua li cas xaiv ntawmFiberglass, Pre-Oxidized Pan, thiab Ceramic Fiber Airgel Pam?
Fiberglass: Rau -200℃-650℃(cov kav dej, cov tsev), hloov tau & raug nqi.
Ua ntej-Oxidized Pan: Zoo tshaj plaws rau -180 ~ 450℃(cov roj teeb lub cev), lub teeb tshaj plaws nrog cov thermal conductivity qis tshaj (0.012 W / (m·K)).
Ceramic Fiber: Haum rau 600℃-1000℃(furnaces), tiv taus thermal shock.
