Aluminum clad wood doors and windows quality identification skills!

第一点

First point

观看整体外观。我们通常说的好的窗户是具备流畅的线形,完美、平整的漆面以及较小的木材色差。

Watch the overall appearance. A good window, as we usually say, has a smooth line, a perfect, smooth finish, and a small color difference in wood.

辨别密封类胶条性能。要有良好的伸缩性与韧性和抗老化性能,最佳的选择是三元乙丙含量较高的优质密封胶条。角逢处胶条安装要紧密,线形需流畅,需要辨别增加强度与气密性。

Distinguish the performance of sealing rubber strip. In order to have good flexibility and toughness and anti-aging performance, the best choice is high-quality EPDM sealant. The corners should be tightly installed and the lines need to be smooth. The strength and tightness should be distinguished.

检查相关的操作。操作方面须承重力极强的五金结构,必须开启关闭灵活,而且要搭接严谨,具有良好的气密性与疏水性能,五金安装要坚固不能出现执手晃动现象,可以轻松实现开启关闭的效果。

Check related operations. Operational aspects must bear the weight of the hardware structure, must open and close flexible, and to lap rigorous, hunqingt.75ix.com chuguib.75ix.com dinuanb.75ix.com songshuiq.75ix.comlfjixie.75ix.comlfzuche.75ix.comwith good air tightness and hydrophobic performance, hardware installation to be solid can not appear handshake phenomenon, can easily achieve the effect of opening and closing.

辨别玻璃压条及木压条对角连接处是否连接紧密。首先缝隙不得大于0.5mm,且需要平整不能有凹凸感，其次外铝45度角组角处需平整不得有高低不平挡手的凹凸现象,还要相对缝隙小于0.5mm。

Distinguish between glass layering and wood layering diagonal connection. Firstly, the gap should not be greater than 0.5mm, and it should be smooth without concavity and convexity. Secondly, the angle of 45 degree group of external aluminum should be smooth without unevenness and convexity, and the relative gap should be less than 0.5mm.

观察油漆的选用。油漆的选择必须为门窗专用漆,目前市场情况需使用水性漆,要具有良好的质感与密闭性,还要抗紫外线耐黄变与褪色,且要喷涂均匀没有色差无尘粒,木材接缝处色差控制在0.2°以内为最好。

Observe the selection of paint. The choice of paint must be a special paint for doors and windows. At present, the market situation requires the use of water-based paint, to have a good texture and airtightness, but also anti-ultraviolet yellowing and fading resistance, and to spray uniform without color difference dust particles, wood joints color difference within 0.2 degrees is the best.

整体厚度是否合适。铝包木门窗需要整体厚度要合适，型材整体厚度不能低于14mm，否则容易出现外铝强度过低在使用过程中容易出现外铝变型或脱落，进而影响窗户的使用。

Is the overall thickness appropriate? The overall thickness of aluminum-clad wood doors and windows should be appropriate, and the overall thickness of profiles should not be less than 14 mm. Otherwise, it is easy to appear that the external aluminum strength is too low in the use process of aluminum deformation or shedding, thus affecting the use of windows.
