门窗在使用前要做到哪几点?
来源: 2018-04-17 17:31:56
铝合金门窗在制作出厂前应进行气密性、水密性等项实验,并对抗风荷载的能力进行测定,对产品确实达到要求指标时,方可进行安装使用。它的性能主要有:强度、气密性、隔热性、开闭性、隔声性和开锁性。
The air tightness and water tightness of aluminum alloy doors and windows should be carried out before making the factory, and the ability to resist wind load is measured. When the product does meet the requirements, it can be installed and used. Its performance mainly includes strength, air tightness, heat insulation, opening and closing, sound insulation and unlocking.

(1)强度强度是指铝合金门窗在压力箱内对窗进行压缩空气加压试验时所承受限力的能力。一般达到1960-2355Pa,高性能的铝窗可达到2355-2776Pa,(2)气密性气密性是指将门窗放在压力箱内,使门窗的前后形成4.9-2.9Pa的压力差,其每平方米面积每小时的通气更(m'),单位是m'/h" m'。一般门窗前后压力差为1000(pa)时,气密性可达8(m3/h?㎡)以下,高密封性能的铝窗可达2(m'/h?㎡)以下。

(1) strength strength refers to the ability of aluminum alloy doors and windows to withstand the limited pressure when the windows are compressed air pressurized. Generally reach 1960-2355Pa, high performance aluminum window can reach 2355-2776Pa, (2) air tightness air tightness refers to the door and window in the pressure box, the door and window before and after the formation of 4.9-2.9Pa pressure difference, each square meter area per hour ventilation (M'), unit is m'/h "M'." When the pressure difference between the front and rear doors and windows is 1000 (PA), the air tightness can reach 8 (m3/h??), and the aluminum window with high sealing performance can reach 2 (m'/h?) below.
(3)水密性水密性是指铝合金门窗在压力实验箱内,对门窗外侧加人周期为2s的正弦波脉动压力风,并向窗加以4L/(㎡.min)的琳水量,连续进行10min施加人工风雨试验,另一面的透水状态。
(3) the water tightness means that the aluminum alloy doors and windows are in the pressure experimental box, the sine wave pulsating pressure wind of 2S is added to the outside of the door and window, and the water of the 4L/ (.Min) is applied to the window, and the artificial wind and rain test and the water permeable state of the other side are carried out continuously.
(4)隔热性隔热性是指铝合金门窗对热对流阻抗能力,即热对流阻抗数值。
(4) thermal insulation is the ability of thermal impedance of aluminum alloy doors and windows, that is, the thermal convection impedance.
