[China Aluminum Network] The use of colored plastic doors and windows is increasing. The color plastic doors and windows mainly rely on the colorization of raw materials used PVC plastic profiles, compared to the plastic doors and windows made of white PVC profiles, color plastic doors and windows with a new, easy to coordinate with the building decoration, surface texture and diverse advantages. Therefore, colored plastic doors and windows are favored and loved by many users.
Because the colored plastic door and window profile is darker than the surface of the white profile, the profile of the plastic door and window is a multi-chamber structure, and the plastic door and window cavity is not connected with the outside or other chambers and is closed to each other. Therefore, under the influence of high-temperature heat, the closed chamber on the outdoor side will be thermally expanded in the closed air layer in the chamber, the degree of expansion in the outdoor side is greater than that in the interior side, and the plastic door frame frame fan shape is deformed accordingly. Therefore, in order to solve the problem of thermal deformation of colored plastic doors and windows, the exhaust holes of the closed chambers connected to the outer surfaces of the colored profiles are drilled so that the air in the chambers communicates with the outside, so that the air in the chambers under high temperature exposure is affected. Can be released after thermal expansion.
According to a survey conducted by DuPont on the Chinese profile market, the application of color doors and windows in the market has increased by 200%-300% every year. Many well-known domestic and foreign profile companies such as Zhejiang Zhongcai, Dalian Shide, Wuhu Conch, Xi'an Gaoke Plastics, Hebei Baoshuo, Beijing Futian, Anhui Guofeng, German Kemeiling, German Vicat, Japan YKK Yoshida Building Materials, Royal Canadian With the introduction of color profile technology, whether it is plastic doors and windows or aluminum doors and windows have joined the ranks of "luster", the color of doors and windows is more and more abundant, and more advanced two-color coextrusion, coating, spraying, thermal transfer and other technical processes, so that doors and windows have More diverse texture and rich colors.
