The production of aluminum alloy doors and windows is through a series of strict tests, reaching the functional objectives of the rules before delivery and installation. So, what are the main properties of ordinary aluminum alloy doors and windows? Let's talk about liefan!
1、 Sealing plan
First of all, the sealing plan of unit doors and windows is the most important. The main structure of sealing is the sealing between the unit and the protection frame and between the cells and the protection box. The seal between two or more seals and between holes should be used to continue the rubber sealing; The protection frame of the sealing structure plan and the hole shall be structured in a different way according to one direction plan, so that the protection between the frames is popular and independent. The entrance waterproof mortar shall be used after sealing the hole. The waterproof silica gel can be used to protect the frame and then seal the window opening between the internal and external finishes.
2、 Waterproofing plan
The waterproof plan is a highlight of doors and windows. It can make waterproof modular plan in the door, double waterproof plan, waterproof plan of the equipment itself. According to the configuration of drainage holes and units in the second layer of the shielding box, besides protection, drainage holes are also opened in the position of connecting the next frame with the main body of the unit. Under normal conditions, rainwater or condensed water indirectly displaces the body from the drainage outlet. If the cell body and the internal drainage of the unit body and the cavity profile condensate are not well drained, the protection box between the rainwater infiltration or leakage can pass through the second layer of waterproof protection box.
Third, energy saving plan
The width of thermal insulation structure can be adjusted according to the requirements of energy saving direction. Due to the unit door and window interface plan and single cavity plug structure, the front door and window unit can easily connect to the side of elastic insulation material (extruded polystyrene material or polyurethane material), which can effectively block the smooth air flow in the cavity of splicing unit. The energy-saving result is far better than other similar energy-saving windows, and also has the results of sound insulation and noise reduction.
4、 Seismic plan
The unit type doors and windows have a special structure with plug-in installation to enhance the displacement of the main structure of the window, which can effectively absorb the ground motion, temperature change and interlayer displacement, which is more suitable for the seismic requirements of different areas than the traditional doors.
