When aluminum alloy doors and windows what should we do when leakage occurs? Not Afraid, let the first-line brand of aluminum alloy doors and windows -- kebitt give us two tricks.
Because the common connection methods of door and window frame in the market mainly include 45 ° set angle and 90 ° straight thread fastening, but 45 ° set angle leakage is also suitable for 90 ° straight thread fastening, so we just say how to solve the leakage of 45 ° angle of aluminum alloy doors and windows.
Causes and Treatment Scheme of 45 ° group angle leakage:
1. When blanking, the 45-degree blanking angle is wrong, or the cutting saw blade is seriously worn and the dynamic balance is not good, resulting in a gap or concave deficiency at the 45-degree angle, resulting in leakage
solution: improve the blanking accuracy of the equipment and replace the saw blade frequently.
2. When the angle is set, the matching gap between the angle code and the frame profile is too large, resulting in looseness or gap at the 45-degree splicing after the angle is completed, resulting in leakage
solution: it is recommended to control the matching gap between the angle code and the profile cavity within 0.2mm, and the force point of the angle code at the cooperation of the squeezing knife, and increase the reinforcement support.
3. When the 45-degree angle is set, the 45-degree section is not coated with sealant, causing water to flow directly into the cavity along the 45-degree section and penetrate into the wall.
Treatment Plan: apply rinse sealant on the 45-degree section before setting angle, preferably sealant with certain extensibility and elasticity.
4. There is no treatment in the cavity of the insulation part of the Broken Bridge insulation profile, causing water to directly enter the corner from this section and seep out
treatment Scheme: design a connector dedicated to the cavity of heat insulation strip, and use glue injection to seal;
5. The connecting corner plug-in is not installed at the flanging of the large surface of the profile (especially when the doors and windows are opened inside). Because there is no angle code here, there is dislocation or gap, causing water leakage.
Solution: design a connection angle plug-in corresponding with the notch, and inject glue at the corner
the above is when aluminum alloy doors and windows what should we do when the 45 ° angle leakage occurs? I hope it can help everyone.
