钢结构厂房的火灾扑救措施之确立“冷却先于灭火”的主导地位发布时间：2015/11/11 10:04:12 浏览次数:671
Steel structure factory steel column in fire, the first in a short period of time lost, the distortions that arise, you may not be significant casualties, and woollen clothes inside the house property, because broken; also after the fall of the Shannon Thai good things, good ventilation, more accelerated fire spread, in a relatively short period of time formed large area fire; there are a lot of piano structure of reactor pressure in also saves more difficult.
Therefore, in order to ensure the safety of the whole structure of the building, the fire fighting is a positive and significant effect. To do this as soon as possible. The cooling effect of piano has the only way. This can be the case of fire environment temperature or ambient temperature changes, enhance the construction of the piano. Their humidity drops, which effectively ensures that the construction of the piano is not damaged. At the same time, the water vapor emitted from the cooling steel structure can lead to the increase of humidity and temperature of fire environment. If the condition of the 100, one kilogram of water into steam. But absorb 253000 calories. At the same time, the 1725 of the volume of water vapor increases the space of the occupied area, not only increases the ambient temperature and air breathing as the same as the air breathing fire extinguisher or hinder the fire spread.
In addition, the cooling water reflects the water has a direct fire. So enough water cooling piano structure big superiority must be cooled before, fire extinguisher, the most important principle of steel structure fire fighting can be two cooling and can not digest the implementation of the hi. Situation in fire. Objective to ask the commander of fire, fire fighting forces with the contrast between the two people is very good combination, according to the different conditions of treatment between cooling and fire. Is in the steel structure deformation, to prevent the collapse of the building under the premise of adequate fire to start with the same time as the cooling and fire and other combustible building components and internal materials, equipment, and the simultaneous deployment of forces in order to cool down and evolutionary forces, must control the threat.
