Stone curtain wall

At present, the consumption of modern curtain wall in China has exceeded 30 million square meters per year, so we can quickly find large buildings with beautiful design and stone curtain wall in any city. But some beautiful buildings can become contaminated less than three years after completion and acceptance, making the whole building look old and worn. This is mainly due to the following reasons:

Use the wrong exterior decoration material.
There are many kinds of stone, different stone products have different durability, corrosion resistance and weather resistance. Also have a lot of stone material suits 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 of aluminium curtain wall. 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, glass stone, etc.
Before installation, attention should be paid to the treatment of wall decoration materials. On the one hand, after choosing the right curtain wall panel, 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; On the other hand, there are larger pores and cracks on the base surface, but also to repair as far as possible.
Unqualified auxiliary materials.
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 construction 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.
