898型铝合金推拉窗性能：

1.抗风压性能:4600pa

  型材壁厚满足铝合金窗国家标准,内外框均采用90度螺丝连接,双边包覆,抗风压强度高.

2.水密性:300pa

  下横料采用高阶梯式设计,两轨道高度差为22mm,防止强风暴雨,致使雨水倒溅入室内的危害,多层排水能顺畅排出回来的雨水,保持气密窗不渗不漏.

3.气密性:0.6m³/(m.h)

  外框下横料设计采用了与型材点接触的密封方式,而且把气密条的端头设计成弧型,保证了其推拉的顺畅性又达到了很好的气密效果.

采用双边包覆设计，外框宽度80mm，无加工缺口外露，结构新颖坚固，整体线条优美，外型美观大方，满足现代人对高品质生活的追求。   Covered by bilateral design, frame width of 80mm, without  processing the exposed gap, strong new structure, the overall lines of beautiful, elegant  appearance, to meet the high quality of life of modern people to pursue.

人性设计，开启舒适    Human design, open comfort

设计师充分考虑了窗功能的互动性，装饰性，协调性和工艺性的综合要求，推拉气密窗的内框料根据人体工程学原理设计，加大扶手的断面设计，使开启更加舒适，手感更加顺畅，如此人性化设计，只为了使您的家居生活更加舒适，安全。     Designers take full account of the interactive features  of the window, decorative, coordination, and process of the comprehensive requirements of  the inner sliding window frame sealing materials designed according to ergonomic  principles, to increase the cross section handrail design, open more comfortable feel more  smooth, so user friendly design, just to make your home life more comfortable, safe.

创新设计，防水性好   Innovative design, good waterproof

下横料采用高阶梯式，两轨道高度差为22mm，内轨道的特殊形状设计使外轨道顶部到内轨道密封槽槽口高度达到了8.6mm。有了这样的高度差，在再大的风雨下，窒外侧的水也不易被吹入室内，同时又加装了排水孔防止水倒流，达到了很好的防水效果。     Materials under high horizontal ladder, the  two orbital altitude difference of 22mm, special shape design inside the orbit to orbit  within the outer track to the top of a high degree of sealing groove notch reached 8.6mm.  With this height difference, in another big storm, the stifling of water is not easily  blown outside the room, while installing a drainage hole to prevent reverse flow of water  to achieve a good waterproof effect.

新型密封，一举两得   New seal, double benefit

推拉气密窗的气密条设计改变了以往传统的直线，一个面与型材接触的密封方式，采用了点接触，而且把气密条的端头设计成弧型，保证了其推拉的顺畅性，又达到了很好的气密效果，一举两得。    Article airtight airtight sliding window design changes the conventional line, a surface  sealing contact with the profile mode, using a point contact, and the sealing strip the  ends of the arc designed to ensure the smoothness of its push-pull also achieved a good  sealing effect, kill two birds.
