comprehensive professional manufacturer integrating development, production and sales of aluminum alloy doors and windows. Since its establishment, the company has established the corporate vision of "global resources, serving China". We not only have professional and excellent production quality, but also high-end door and window design that keeps pace with the times, it also invests a lot of money to introduce advanced equipment at home and abroad. At the same time, it also pays attention to the selection and introduction of talents, and never forget the innovation and reform at all times, so as to meet the higher requirements of modern families for safe and comfortable life, practice the enterprise spirit of "scientific enterprise development, talent-oriented" of doors and windows in Han and Tang dynasties with practical actions. After years of technological precipitation and brand sublimation, Han and Tang doors and windows have become a vigorous "Dark Horse" in the door and window industry with high quality products and popular sales reputation ", at the dawn of the new era, the enterprise glory belonging to the doors and windows of Han and Tang dynasties will bloom again and again!
Watertightness of doors and windows
1. The water tightness of aluminum alloy doors and windows is related to the strength of aluminum alloy doors and windows, section and material of adhesive strip, drainage system, window structure design, etc. The adhesive strip adopts EPDM, it can ensure good elasticity and aging quality resistance, but the rain water in the glass groove sealed with adhesive strips will still leak in, because it has milling drainage holes and grooves.
2. Outwards opening window in the open state, rainwater will flow into the inner cavity from the keyhole of the actuator, causing corrosion and friction lined steel the inner cavity? Does chain screw Rust affect window and friction? Chain connection strength, therefore, after the actuator is installed at Keyhole, the gap should be sealed with glue.
3. The splicing place of aluminum alloy doors and windows is also the way of rainwater leakage, especially in the case of rainstorm and typhoon, which is more serious. Therefore, we use imported corner glue on the splicing, which is more sealed and firm.
4. The design of the connection node between the window frame and the Wall also directly affects the watertightness of aluminum alloy doors and windows. The correct approach should be one-component Styrofoam fill plug gap. At the same time, the Wall glue uses one-component neutral silicone sealant.
5. In the design of arc fixed windows, it is difficult to match the arc of curved glass with the arc of the frame. In special circumstances, the design should be considered as external glue sealing.
Air tightness of doors and windows
1. The air tightness of aluminum alloy doors and windows is related to the strength of aluminum alloy doors and windows bars, the sealing effect of adhesive strips, the gap between bars, the spacing between locking points, hardware assembly and processing precision, etc. The air tightness of the Northern project is particularly important due to the cold winter.
2. Plastic windows are easily deformed due to their poor strength and rigidity, resulting in serious air leakage. Is the solution?? The number of locking points. In our general design, when the fan height and fan width size exceed 1200mm, we should consider adding locking points, and the spacing between locking points should not be greater than 600mm.
Can the hinge side of the window be pressed?? The hidden hinge is added to achieve the sealing effect. The hinge side of the inner hanging window is close to the intermediate lock. In the previous design, the window generally chose a single locking point intermediate lock, but the locking point is far away from the upper rocker arm hinge, the sealing effect is still not guaranteed, especially for high-rise buildings, so in the design, 500mm single lock point intermediate lock can be selected if the fan height is less than 1400mm, for Fan height greater than 1400mm, two locking points intermediate lock should be selected to ensure better sealing effect.
Push and pull aluminum alloy door and window lock points have little effect on sealing, so the design of single locking point can be considered. When designing the window, when the width of the fan exceeds 900mm, a hidden intermediate lock should be placed horizontally on the fan. Casement window generally, the fan horizontal design cannot exceed 800mm, and no locking point can be set.
