| Abstract: | Fire blocking obstruction is an important measure used in electric cable channel in power station, metallurgy and communication trades. According to the character of firing mishap in electric cable channel, we have designed a new fire - blocking door of electric cable channel based on the mechanics and thermal conductive principle. The fire - blocking limit of the fire - blocking door, which used cold rolling sheet steel and fibred felt of aluminum silicate as the main material, is above 72 min. With the studies of performance of thermal conductivity of the door, the theoretical foundation of design and development of the door has been built. |
