The performance of aluminum alloy doors and Windows

Aluminum alloy doors and Windows must undergo strict performance test before the factory can be installed. Aluminium alloy doors and Windows usually assess the following main performances:

1. The strength of the strength aluminum alloy doors and Windows shall be indicated by the rating of wind pressure in the compressed air pressure test in the pressure box. The unit is N/m2. The general performance of aluminum alloy doors and Windows can reach 196l ~ 2353 N/m2, and the high performance aluminum alloy window can reach 2353 ~ 2764 N/m2. Under the above pressure, the maximum displacement in the center of the window should be less than l / 70 in the frame.

2. The air-tightness aluminum alloy window is in the pressure test case, the pressure difference between the window is formed 4.9 ~ 9.4 N/m2, each of the m2 area of the measure (m3) is the air tightness of the window, the unit is m3 / (h &# 8226; m2). When the pressure difference is 9.4 N/m2, the air tightness can reach 8m3 / (h & # 8226; m2). The high sealing aluminum alloy window can reach 2m3 / (h & # 8226; m2).

3. The water tightness alloy window is in the pressure test case, the outside of the window is added the period to be the sine wave pulse pressure of 2s. At the same time, the window was sprayed with 4L of artificial rain for every m2 of m2, and the "wind and rain" test was conducted continuously for 10min. The leakage of water on the side of the indoor side should not be visible. The average pressure of the pulse pressure exerted by the water tightness test is indicated. The general performance of aluminium alloy Windows is 343N/m2, and the anti-typhoon performance window can reach 490N/m2.

4. The acoustics of the aluminum alloy Windows were tested by acoustic insulation in the sound laboratory. It can be found that when the sound frequency reaches a certain value, the sound of the aluminium alloy window becomes constant through the loss. This method is used to determine the hierarchical curve of sound insulation performance, and the sound transmission of aluminium alloy window with sound insulation requirement can reach 25dB, which means that the sound can be reduced by 25dB through the aluminum window. High acoustic performance of aluminum alloy Windows, the sound through the damage grade curve 30 ~ 45dB.

5. Insulation is usually expressed by the thermal convection impedance of the window. The unit is m2 & # 8226. H & # 8226; C/KJ. It is generally divided into three levels: R1 = 0.05, R2 = 0.06, R3 = 0.07. The thermal convection impedance of 6mm double-glazing glass with high performance can reach 0.05 m2. H & # 8226; C/KJ.

6. Nylon guide wheel durability push-pull window and movable window of the activity window are used for continuous reciprocating test by eccentric connecting rod mechanism, and the nylon wheel diameter of 12 ~ 16mm is tested 10000 times; Nylon wheel diameter 20-24mm trial 50,000 times; The nylon wheel has a diameter of 30-60mm and 100, 000 times. The accessories such as window and guide wheel are not damaged.

7. When the open and closed force is installed, the external force of the window opening or closing shall be below 49N.

8. The open locking durability can be driven by the power motor on the test platform and continuous open and closed test at the speed of every min10 ~ 30 times, and no abnormal damage should be done when reaching 30,000 times.
