塑钢门窗是在八十年代初期通过引进国外先进技术和设备,用硬质PVC异型材,腔内衬有增强型钢制作的新颖门窗,十余年来,各有关部门和单位对引进的技术和设备进行了消化吸收工作,并有针对性地开展了一系列攻关活动,基本掌握了塑钢门窗型材的挤出,门窗组装的工艺技术和大部分设备的制作技术。对抗老化性能在配方中采用进口的金红石型钛白粉,使型材的耐久性增至20～30年有了切实可能保证。
Plastic steel doors and windows were introduced in the early 1980s through the introduction of foreign advanced technology and equipment, with rigid PVC profile, the cavity lined with enhanced steel production of novel windows and doors, more than ten years, the relevant departments and units of the introduction of technology and equipment Digestion and absorption work was carried out, and a series of targeted activities were carried out in a targeted manner to basically grasp the extrusion of plastic steel door and window profiles, the assembly technology of doors and windows and the manufacturing technology of most of the equipment. Anti-aging performance in the formula using imported rutile titanium dioxide, so that the durability of the profile increased to 20 to 30 years with a real guarantee.
