During the acceptance of housing quality, many householders will pay attention to the acceptance of large spaces such as kitchens, bathrooms, bedrooms, living rooms, etc., and may also remember the acceptance of details of small activities such as water and electricity development and cabinets, however, China has not forgotten to analyze and inspect the sealing performance of aluminum alloy doors and windows. Broken bridge aluminum doors and windows adopting heat insulation broken bridge aluminum profile and hollow glass, it has the functions of energy saving, sound insulation, noise protection, dustproof, waterproof and so on. Aluminum alloy doors and windows made of aluminum alloy extruded profiles as frames, mullions and fans are called aluminum alloy doors and windows, which are referred to as aluminum doors and windows for short. Aluminum alloy doors and windows include wood and plastic composite doors and windows with aluminum alloy as the base material of stressed bars (bars that bear and transmit self-weight and load), referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. System doors and windows a perfect and organic combination of performance systems, water tightness, air tightness, wind pressure resistance, mechanical strength, heat insulation, sound insulation, anti-theft, sunshade, weather resistance, A series of important functions such as operating hand feeling should also consider the comprehensive results of the performance of equipment, profiles, accessories, glass, viscose and seals, which are indispensable and finally form high-performance system doors and windows. It was not until the students found that the enterprise would get into the wind even though it was tightly closed through the windows after they checked in. At this time, the teacher was late. So how to improve the sealing performance of aluminum alloy doors and windows during inspection?
I. Check the sealant strip
the window pressing strip is divided into glass sealing strip and wool tops .. to seal the window, it must be carried out with sealing tape at the beginning and end of the strip and inner fan, only in this way can the glass and frame fan be thinner, thus ensuring the air tightness of the window. Therefore, when checking, you can carefully check whether there is a Sealing Strip. The surface of the sealing strip should be smooth, smooth and straight. The interface should be meticulous and neat to see whether these key points conform to these principles..
Second, look at the gap between aluminum alloy doors and windows
it is common for students to think that water leakage only occurs in a bathroom, kitchen, top floor and terrace. However, if there is no gap between the door frame and structural design of aluminum alloy doors and windows, filling materials and filling quality of life are not well managed, under the influence of certain wind pressure intensity, when funds are broken or damaged, or the gap between the two other door leaves or the horizontal and vertical joints between the door and the frame is too large, it is easy to lead to the situation that a large amount of rainwater is poured back into households, which directly causes damage to the fine decoration of enterprise owners. In addition, it is also directly related to the problems of national energy conservation and noise. This kind of learning situation analysis, especially in oriel window, is more likely to occur. Therefore, it is suggested that the owner of the house can be divided into intentional inspection and understanding of the gap filling materials and filling teaching quality between the door frame and the structural adjustment to see if there is any damage.
3. Check whether the aluminum alloy door and window profile square meters are uneven
the main reason for air leakage of aluminum alloy doors and windows lies in the tightness between aluminum doors and windows fan and the frame, and the flatness of the profile is an important factor affecting the tightness. If the flatness of the profile is not enough or deformed, there will be a certain gap between the aluminum doors and windows fan and the frame, resulting in air leakage. Therefore, if aluminum alloy door and window profile is uneven or deformed, contact the manufacturer in time to remove the old aluminum alloy doors and windows and install the new aluminum alloy doors and windows.
4. Check whether there are cracks in the information between the frame and the wall material.
During the installation and construction of aluminum alloy doors and windows, many Chinese workers did not do their own work on the sealing system between door frames, window frames and walls due to rush to work or cutting corners. If this problem can be found in the process of acceptance management, the professional and technical personnel of the students should be contacted to come to the door and glue it again.
5. Check whether the hardware is locked firmly.
The quality of aluminum alloy and door and window hardware is also closely related to the tightness, especially the direct opening of the window. It relies on the actuator of the hardware to analyze and seal. If the quality management of a actuator is not good, easy air leakage from Casement edge system. Therefore, in the process of project acceptance, you must try it yourself.
