uPVC Profile door and window companies are basically the same in the use of manufacturing equipment. The products of this material have gradually been widely used. However, with the uneven weight of the products on the market, we need to master the ability to distinguish the quality of plastic steel profiles. In terms of information, I will explain in detail for everyone:
According to uPVC Profile merchants, with the development of technology, most of them use ultra-fine lightweight activated calcium carbonate, even nano-scale calcium carbonate, which not only increases rigidity and filling, but also has a modification effect, but its The amount of filling is not unlimited, and its proportion should be controlled. Now some manufacturers add calcium carbonate to 20-50 parts by mass in order to reduce costs, which greatly reduces the physical and mechanical properties of the profiles, resulting in the brittleness of the profiles mentioned in this chapter. Plastic-steel profile merchants, the rainwater of aluminum alloy doors and windows in construction projects Leakage is the most common phenomenon in the use process, and it is more difficult to cure. It has a great impact on the quality of construction projects, and the economic losses caused are even more unpredictable. With the large-scale development of China's civil housing, residential buildings are becoming more and more high-rise, facing the needs of building lighting and appearance beautification, and the single area of doors and windows is becoming larger and larger, causing the problem of rainwater leakage to become more and more prominent. The rainwater leakage phenomenon of aluminum doors and windows is also widespread and similar in other materials of doors and windows, and some are more severe. Therefore, it is necessary to analyze and deal with the rainwater leakage of aluminum doors and windows. This not only solves the problem of rainwater leakage of aluminum doors and windows, but also has the same guiding significance for rainwater seepage of other types of doors and windows.
I believe that the above information can help you better distinguish the quality of uPVC Profile. Only in this way can you choose better plastic steel profile products. More information about plastic steel profiles will continue to be organized for everyone. I hope you can have more information Helped.
