As the air quality continues to deteriorate, the occurrence of haze weather phenomena increases and the damage increases. In many areas of China, the haze weather phenomenon is incorporated into the fog as a warning for severe weather warnings, collectively referred to as “smog weatherâ€. So what is the impact of smog weather on our home life, and how to reduce such adverse effects, Jiuzheng Building Materials Network Xiaobian will spread the relevant knowledge for everyone.
The three components of sulphur dioxide, nitrogen oxides and respirable particulate matter are the main components of smog. The first two are gaseous pollutants. The last particulate matter is the main culprit for aggravating smog weather pollution. The granule itself is both a pollutant. It is also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons, which is extremely harmful to home life.
Reducing the source of pollution and reducing atmospheric pollutants are the fundamental way to solve the haze, but it is not a day's work. Windows are the most vulnerable part of the structure of the house, so improving the overall performance of the window is the most realistic and most critical way to reduce the haze of home life.
In addition to the quality of the window itself affecting its performance, the way the window is opened is also an important factor.
In the three properties of the window (wind resistance, water tightness, air tightness), the casement window is generally superior to the sliding window. The wind-resistant performance of doors and windows depends on the resistance moment of the main force-receiving rod of the door and window. The larger the section of the profile, the larger the resistance moment. The profile of the casement window is small, but the main force bar is a piece of material or a vertical material. These main force bars are strengthened in the design process, so the wind pressure resistance is better. . The cross-section of the sliding window profile is generally large, and it is reasonable to say that its wind pressure resistance performance should be better, but as long as the analysis of the force is slightly deepened, it is known that the main force member is often the middle fan material, and the upper and lower jaws are only by the pulley. To withstand wind loads in the horizontal direction, the wind pressure resistance is generally not ideal. The watertightness of the window depends on the sealing effect of the opening part, and the casement window is generally sealed by a plurality of rubber strips. In terms of air tightness, the opening fan of the casement window on the market is more tightly locked by a two-point lock or a heaven and earth lock. Therefore, the casement window is generally better than the sliding window in terms of three performances.
In summary, the casement window is superior to the sliding window in performance. For this reason, the casement window is widely used in urban and commercial buildings, office buildings, high-end residences, villas and other medium and high-end buildings, while sliding windows are widely used in industrial plants, rural houses and other low-end buildings.
Functional Masterbatch is one general catagory for all masterbatches which prosses some special functions or performance, such as anti-static, anti-block, PP clarifying, rust-proof, unclearating so on. Its carrier is special polymer, with funcational additives. The colorsare transparent or ivory.
