Full-scale simulation experiment was carried out to study smoke-proof characteristics of inorganic smoke-proof rolling curtain under mechanical exhaust condition

and the average unexposed surface temperature of rolling curtain and smoke flow passing inter-curtain′s slot were measured.The results show that the inorganic smoke-proof rolling curtain automatically fall to the ground when the fire break out

and within the 20 min′s test time

the smoke could be controlled in the fire area by inorganic smoke-proof rolling curtains

only little smoke enters into atrium;the unexposed surface temperature of rolling curtain is close to ambient temperature.Because of the good behavior in block smoke and heat-resistant

the inorganic smoke-proof rolling curtains can make sure the safe evacuation in the case of fire.This study provides the experimental support for application of the new inorganic smoke-proof rolling curtains to complex atrium.
