塑料窗是一种新型材料外窗,它具有适于机械化大规模生产、易于制成复杂断面型材的特点,因而易于制成气密、水密、保温性能良好的外窗系列产品。目前已形成主要实用窗型之一。但是由于塑料型材的材性所限,其刚性差,须在型材空腔中插以衬金加强;同时,由于塑料易受日光中紫外线作用而褪色,故很难制成多种颜色。此外,由于塑料型材难以达到铝合金和彩色钢板型
Plastic window is a new type of material outside window, which has the characteristics of being suitable for large-scale production of mechanization and easy to make complex cross-section profiles. Therefore, it is easy to make exterior window series products that are airtight, watertight, and have good heat insulation performance. At present, one of the main practical windows has been formed. However, due to the limitation of the material properties of the plastic profiles, the rigidity of the plastic profiles is poor, and it is necessary to insert lining gold in the profile cavity to reinforce; at the same time, since the plastic is susceptible to ultraviolet rays in the sunlight and fades, it is difficult to make a variety of colors. In addition, it is difficult to reach aluminum alloy and color steel plate types due to plastic profiles.
