Description
Technical Field
The utility model relates to the technical field of anti-condensation roofs, in particular to an anti-condensation metal roof.
Background
The condensation is that when unsaturated air is cooled to a certain temperature, the unsaturated air reaches a saturated state, and after the unsaturated air is cooled continuously, excessive water vapor is condensed into water droplets, namely commonly called as condensation, and the critical temperature is called as dew point. Whether condensation occurs depends on the indoor temperature and the dew point temperature. Even if the dew point temperature does not drop to be flush with the outdoor temperature, condensation may occur at a certain indoor temperature.
When the condensation phenomenon occurs on a building, it is generally called building condensation. Building condensation is often divided into surface condensation and interior condensation. The surface condensation is a phenomenon in which when the indoor air is in contact with a surface and ceiling below the dew point temperature when the indoor air humidity is higher than the outdoor air humidity, water vapor is condensed into water droplets. The internal condensation is a phenomenon of condensation generated when water vapor is blocked at a low temperature portion when passing through a wall body and a roof under the action of a vapor pressure difference.
In general, since indoor ventilation is poor in winter and a large amount of water vapor is generated in daily life, the absolute content of the water vapor in indoor air must be higher than that in outdoor, so that dew condensation phenomenon is easily caused in a certain area of a wall body along with the reduction of the temperature of the wall body in the process of outward diffusion.
When certain dewing phenomenon occurs on the roof, the heat insulation material inside the roof absorbs water or moisture, so that the heat insulation performance of the heat insulation material is greatly reduced, because the heat conductivity coefficient of water is m.K and is far greater than the heat conductivity coefficient (m.K) of air and the heat conductivity coefficient of a common heat insulation material (such as the heat conductivity coefficient of aerated foam concrete is m.K). Therefore, the building dew can reduce the heat insulation performance of the building material, meanwhile, the strength and the durability of the building material are affected to a certain extent, and as the temperature and the humidity are proper, a good living environment is provided for bacteria, the mildew and the damage of a decorative layer are easy to cause, particularly, mould can propagate in a large amount under the conditions of the temperature of 25-30 ℃ and the humidity of more than 80%, and sufficient oxygen, and the fungus can be actively propagated, so that the harm to the human health is easy to cause.
