According to the raw materials, the windows can be divided into three major categories: wood, plastic (steel) and aluminum alloy. In the plastic (steel) window, the plastic material is used, so the weight is small, the heat insulation function is good, and the price is relatively low. Regarding plastic (steel) windows, Tang Ju, deputy secretary-general of the China Building Metal Structure Association, told reporters that the "plastic steel doors and windows" that are well known to everyone are different for other household plastic products, and they are actually called this. Plasticized polyvinyl chloride (puv-u) plastic steel doors and windows, so the standard title should be "plastic steel doors and windows."
In the application process of plastic steel doors and windows, everyone is most concerned about the deformation of plastic steel doors and windows. In this regard, Tang Ju showed that the deformation of the window is mainly the thin wall of the profile, the size of the reinforced steel is smaller than the gap of the profile, so the effect of strengthening is not achieved, and the overall rigidity of the window is small. Of course, some companies have low planning and manufacturing skills. The function of the window is not up to the norm. In this regard, the state has new normative rules to ensure the thickness of the profile wall, which will reduce the appearance of deformation. In the meantime, what cannot be ignored is the skill impact of unqualified goods on the entire profession.
Regarding the retraction of plastic steel doors and windows and touching environmental concerns, Tang Ju informed reporters that plastics are not easy to degrade, but compared with combustion and burial methods, recycling and recycling is an increasingly environmentally friendly recovery method. At present, there is such a skill that the plastic doors and windows are retracted and crushed and crushed, and the raw materials are not separated from each other, and then the materials are used from the beginning according to the quality of the materials. The good quality can be processed into the profiles again, and the quality can be The downgrading process is used as other auxiliary profiles. Moreover, the energy consumption of this method of retracting is also very low.
