Maintenance of aluminum alloy doors and windows.
Push gently.
When using aluminum alloy doors and windows, remember to push hard and stretch, you should follow it naturally. If you find that push -pull is hindered, do not work hard. You should check whether there is something hindered or deformation of the doors and windows. Keep it clean, especially pushing the sliding tank. If there is dust, it will easily affect the push.
Second, don't squeeze the aluminum frame.
Generally speaking, when cleaning aluminum alloy doors and windows, do not stand on the aluminum frame. The weight of a person can easily cause the aluminum frame to deform, and do not support it with aluminum frames.
No. 3 aluminum, choose the appropriate cleaning agent.
Aluminum doors and windows cannot be used to use strong acid and alkali cleaning agents such as dirty powder or toilet. These cleaners will corrode the aluminum doors and windows, nor can they use soap or washing powder. Generally, wash with water.
Fourth, it is strictly forbidden to slide water.
If there is rainwater hoarding in the sliding, you should apply dry and wet glass and doors and windows frames in time. Pay special attention to drying and sliding water for a long time. Essence
Fifth, often check the damaged parts.
To check the damaged parts of the doors and windows, regularly add lubricating oil to keep clean and spiritual aluminum work. For the frame link site, it should also be checked regularly, tighten the bolt in time to replace the damaged parts and sealing wool strips and glass glue.
How to measure the hardness of aluminum.
1. The hardness should be selected within a small temperature change range, because temperature changes may affect the test results, so the test generally stipulates that at a room temperature of 10-35 C. And make the head axis perpendicular to the surface of the sample to avoid displacement of the sample.
2. In contact with the surface of the sample, the test force is applied without impact and vibration. The initial test force should not be maintained for more than 3 seconds. The force increases to the total test force, and maintains 4S 2S, and then removes the main test force to maintain the initial experimental power. After a short stability, the readings are performed. In order to read the number accurate, during the test, the hardness meter should avoid any impact and any impact and shock.
3. When taking the value in multiple places, the distance between the center of the two neighbors should be at least 4 times the diameter of the indentation, but it should not be less than 2mm. Be more, but not less than 1mm, aluminum.
