Use the wrong exterior decoration material.
There are many kinds of stone, and different stone products have different durability and corrosion resistance. Also there are a lot of stone material suit indoor use only, cannot use at complex changeful outdoor natural environment. If used for a long time, its performance and hardness will be affected to a certain extent.
In addition, there are some stone, such as sandstone, the surface has many pores. With the passage of time, it is easy to produce mildew, and even grow moss, which will bring great trouble to the later maintenance work for curtain glass window. In practical work, we should analyze the situation in detail. Through careful investigation and analysis of the climatic conditions around the building and the actual requirements of engineering design, we try to choose appropriate stone materials as curtain wall materials, such as granite, etc.
Before installation, attention should be paid to the treatment of wall decoration materials. On the one hand, after choosing the right stone panels, it is necessary to soak and protect them to avoid the pollution of other pollution sources. As far as possible to ensure that waterproof measures in place, no water leakage in the modern curtain wall; On the other hand, there are larger pores and cracks on the base surface, but also to repair and smooth as far as possible.
Unqualified paving material.
Stone sealant is the biggest pollution source of stone panel. Because of its material characteristics, in the stone erosion process, sealant often from the stone edge to the internal infiltration. Over time, no matter how clean it is, it cannot be effectively cleaned.
So in the construction process to choose good quality sealant, sealant can be used before oil leakage test. Only non-polluting sealant can prevent a variety of pollutants and oily substances into the stone caused by pollution.
In addition, the curtain wall structure should be made of stainless steel or aluminum alloy connection. In the past, stainless steel was generally used more widely for cost reasons. But there are some construction enterprises cut corners, with stainless iron as a substitute.
In the early stage of building construction, inferior transfer hanging pieces will not have a great impact on the building. With the increase of service life, the galvanized layer on the metal surface will be eroded and oxidized by rain and air, forming iron oxide, and rust is easy to penetrate into the connection part, resulting in rust on the stone panel. Therefore, in the construction process, we must strictly control the quality of the transfer pendant to avoid such situations.
If the curtain wall is polluted, no matter it is cleaned, maintained or replaced, it will bring great cost to the property company and developer. Therefore, we carefully analyze all possible reasons that may lead to pollution of stone curtain wall, and suggest that you can choose the glass stone that is easy to construct, resistant to pollution and easy to maintain for exterior wall decoration, which can greatly eliminate the later maintenance cost.
