铝合金门窗加工中中控玻璃失效的原因

先量好窗户的大致尺寸，做到胸中有数。市场上销售的窗户均是负责安装的，有些不法商家测量时会虚报尺寸，以赚取更多利润。铝合金门窗加工设备货比三家，任何时候购买东西都不要忘了货比三家，货比三家不光在于比较价格，多看多问有利于自己鉴别产品质量。
Take the amount of roughly the size of the window, do know what. Windows sold on the market are responsible for the installation, some illegal businesses will be measured in false size, in order to earn more profits. Aluminum alloy doors and windows processing equipment, goods than three, at any time to buy things, do not forget the goods than three, more than three goods, not only in comparison prices, more see more, ask themselves to identify the quality of products.
传热系数K反映玻璃温差传热特性，实木门通常以樱桃木、黑胡桃木、花梨木、沙贝利为主要材质有柚木、黑檀木.中空玻璃失效的直接原因：间隔层内露点上升。

The heat transfer coefficient of K reflects the glass temperature difference of heat transfer, solid wood door usually with cherry, black walnut, rosewood, Sabelli as the main material of teak, ebony. The direct cause of failure: the hollow glass spacer layer in the rise of dew.

铝合金门窗加工设备当环境温度降低到使玻璃表面的温度低于间隔层内的露点时，间隔层内的水汽便在玻璃内表面产生结露或结霜（玻璃内表面温度高于0℃时结露,低于0℃时结霜）。
Aluminum Alloy doors and windows processing equipment when the ambient temperature is reduced to the glass surface temperature is lower than the dew point within the spacer layer, spacer layer in the water vapor in the inner surface of the glass to produce dew or frost (in the glass surface temperature is higher than 0 DEG C below 0 DEG C when the dew, frost).
有效地降低了从门窗传导进入室内的热量；带有隔热条的型材内表面温度与室内温度接近，地降低了室内水分由于过度饱和而冷凝在门窗表面的可能性；在冬季的寒冷天气里，带有隔热条的断桥铝门窗框，至少能够减少1/3的通过门窗框而散失的热量；而在炎炎夏季，带有隔热条的门窗框能够地阻挡来自室外的炙热气流，如果有空调，也相对地减少了空调能量的损耗，同时减少了由于空调和暖气产生的环境辐射，铝合金门窗加工设备真正地节能环保人体与环境交换热量取决于室内空气的温度、空气流动速度和室外空气温度。
To effectively reduce the heat into the room from the window with a heat conduction; profiles in surface temperature and indoor temperature to minimize indoor moisture due to excessive saturated and condensed in the possibility of doors and windows surface; in the winter cold weather, with the broken bridge insulation aluminum door and window frame, at least to reduce 1/3 through the window frame and the heat loss; and in the summer heat, with a heat insulation window frame to maximize the hot air coming from outside the barrier, if there is air conditioning, reduced loss of air conditioning energy, simultaneously reducing the radiation generated by the air conditioning and heating environment, Aluminum Alloy truly energy-saving doors and windows processing equipment environmental protection of the human body and the environment depends on the heat exchange between the indoor air temperature, air velocity and outdoor air temperature.
中空玻璃的边部密封情况：一方面，如果中空玻璃的边部密封不好，则水气通过密封胶层进入中空玻璃内部的比例应以增大，中空玻璃寿命就会减少；另一方面，如果中空玻璃的边部材料的导热性能好，那么通过中空玻璃的隔热系数就会提高，隔热性能就会下降。
The edge of the hollow glass sealing situation: on the one hand, if the edge of the insulating glass seal is not good, then the water vapor through the sealing glue into the hollow glass internal ratio should be increased, the life of hollow glass will be reduced; on the other hand, if the thermal conductivity of the edge of the hollow glass material, then through the insulation coefficient will be hollow glass improved insulation performance will decline.
玻璃的热透率：中空玻璃的传热主要以辐射传热的方式进行，如果采用高透过率低反射率的普通透明玻璃，则中空玻璃的隔热性能，较采用高反射低透过的镀膜或ＬＯＷ－Ｅ玻璃的低许多。
Glass thermal transmittance: heat insulating glass mainly with radiation heat transfer mode, if the high transmittance of ordinary transparent glass low reflectivity, while the heat insulation performance of hollow glass, many low high low reflection coating through LOW or E glass.
