1. Plastic steel window can be processed. In the molten state, plastic has relatively high fluidity. Therefore, a precise cross-sectional structure can be formed by the mold, thereby realizing the functional requirements of the window. Moreover, a divided chamber can be formed to improve the function of heat insulation, sound insulation and drainage of the window, and the corrosion of the reinforced steel can be avoided.
2. Plastic-steel window energy-saving plastic window has superior technical characteristics in terms of energy saving and improvement of indoor thermal environment. According to the Institute of Physics of the Institute, the heat transfer coefficient of single glass steel and aluminum window is 64W/M2K; the heat transfer coefficient of single glass plastic steel window is about 47W/M2K; the heat transfer coefficient of ordinary double glazing steel and aluminum window It is about 3. 7W/M2K; and the heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K. The window accounts for 30% of the area of ​​the building's outer protective structure, and its heat dissipation accounts for 49%. It can be seen that the plastic steel window has good energy-saving benefits.
3. The sound insulation performance of steel and steel windows is about 19 decibels, and the sound insulation performance of plastic steel windows can reach more than 30 decibels. In an increasingly noisy urban environment, the use of plastic-steel windows makes the indoor environment more comfortable. According to the information provided by Japan, in order to achieve the same noise reduction requirements, the distance between the building with aluminum windows and the main road must be 50 meters, and the installation of plastic steel windows can reach 18 meters. According to the test of the Beijing Municipal Labor Protection Research Institute, the indoor noise using plastic-steel windows has dropped to 32DB (A), and the effect is very good. Due to the development of the economy, urban noise problems are becoming more and more serious, and plastic-steel windows will greatly contribute to improving the quality of the sound environment in which people live and work. In addition, the plastic steel window is corrosion-resistant and can be used in corrosive environments such as coastal areas and chemical plants. The use of ordinary users can also reduce the labor and cost of maintaining paint.
4. The appearance of plastic steel window can be adapted to the domestic decorative effect requirements, and the human body feels more comfortable than metal. Because plastic steel windows have some outstanding advantages, they are getting a lot of applications in China and become a new trend in the construction field.
5. Compared with aluminum alloy windows, the cost of plastic steel windows is 30%-60% lower than that of aluminum alloys. This is the most important reason for the popularity of plastic steel windows.
