As the sky gradually cools, winter arrives. Steel structure engineering indoor color plate condensation problem? It is especially important. Sichuan Xirong steel structure steel structure summarizes a lot of this convenient construction experience in the construction process. Now I will briefly introduce to you the solution to frosting of Sichuan steel structure indoor color board.

First, make a steel structure heat insulation layer, eliminate water vapor, and there is no cold bridge between the indoor wall and the outdoors

1. The reason for condensation is that the temperature of the plate is lower than the dew point (the temperature at which condensation occurs), and there is water vapor in the room. The solution is to increase the thermal insulation effect of Sichuan steel structure, so that the difference between the surface temperature and the room temperature ratio of the plate is generally within 3 degrees.

2. Chengdu steel structure glass wool absorbs a lot of water, and the heat preservation effect is greatly reduced after water absorption. It is recommended to make a steel structure vapor barrier layer (that is, reinforced aluminum foil or white polypropylene veneer, which is required to be pasted indoors) to prevent water vapor from entering the insulation layer. And improve the insulation thickness, generally increased to 1.7 times.

3. Increase ventilation, ventilation will reduce the room temperature, reduce the

temperature difference on the surface of the plate, and reduce the relative humidity in the Sichuan steel structure engineering room.

4. Suspended ceiling, forming an attic. The air compartment itself is insulated, and at the same time, the attic can be ventilated separately.

5. Steel structure metal roof roof special power-free turbine ventilation ventilator and roof ridge ventilation ventilator, one-time cost investment is high, energy consumption and maintenance cost in production and use is almost zero, reasonable design and arrangement can ensure good results within the scope of the plant, but loss of indoor heat.

The above is the solution to the problem of indoor color plate condensation of steel structure engineering summarized in

the actual construction process of Sichuan Xirong steel structure. I hope everyone will continue to pay attention to the Xirong steel structure. We will introduce you to the knowledge of steel structure construction at any time.
