我国塑料门窗十年发展的经历虽然与德国发展初期有许多相似之处,但更有着令人深思的地方.我们的起点要比德国当时的起点高得多,但推广应用的情况不尽人意.究其原因,其中,主要的一点就是没有结合国情,盲目照搬.具体地说就是对窗型材的结构、功能不加分析,应用的环境不加选择,造成了使用上的错位.我厂在这一点上就有过经验教训.比如,我厂引进的60系列双玻窗型材,前些年在华中地区推广效果不甚理想,因截面尺寸大,影响通风采光效果.型材密度大,导致价格上缺乏竞争力.近几年来,通过在东北地区使用证明,效果很好,到此才算找到了用武之地. Although the experience of ten years of development of plastic doors and windows in China has many similarities with the early stages of development in Germany, it has more thought-provoking places. Our starting point is much higher than the German starting point, but the promotion and application of the situation is not satisfactory. The reason is that the main point is that they do not combine national conditions and blindly copy. Specifically speaking, the structure and function of window profiles are not analyzed, and the applied environment is not selected, resulting in misalignment in use. Our factory is here. For example, the 60 series of double glass window profiles introduced by our factory, the promotion effect in the Central China region in previous years is not ideal, because of the large cross-section size, affecting the effect of ventilation lighting. The profile density is high, resulting in price The lack of competitiveness. In recent years, through the use of proof in the Northeast, the effect is very good, only to find a place to use.
