Therefore, broken bridge aluminum alloy doors and windows have become the trend of household doors and windows, and are superior to ordinary aluminum alloy profiles in terms of practical household functions such as energy saving, sound insulation, sound insulation, dustproof, and waterproof. 1. The use of heat-insulating broken bridge aluminum alloy profiles reduces heat conduction and is not easy to deform due to temperature, which greatly prolongs the service life of doors and windows. 2. Prevent condensation. The temperature of the inner surface of the profile with heat insulation strips is close to the indoor temperature, which reduces the possibility of super-saturated water condensation on the surface of the profile. 3. Environmental protection can reduce energy consumption and environmental radiation caused by air conditioning and heating 4. In order to reduce noise, the hollow glass structure of different thicknesses and the hollow structure of the thermally insulated aluminum bridge can effectively reduce the resonance effect of sound waves, prevent the propagation of sound, and reduce the noise by more than 30dB. 5. Energy saving and environmental protection in winter. Window frames with thermal insulation strips can reduce the heat loss through the window frame by 1/3 and are used for indoor heat preservation; in summer, if the room has air conditioning, the broken aluminum windows with thermal insulation strips can reduce energy loss and keep the home warm , Reduce the energy consumption of air conditioners, save energy and protect the environment. 6. The aluminum alloy doors and windows with superior structure and broken bridge are the most advanced aluminum alloy doors and windows at present. It is the fifth generation of new thermal insulation and energy-saving doors and windows after wooden windows, iron windows, plastic steel doors and windows, and ordinary color aluminum alloy doors and windows. Due to the influence of weather, environment, human factors and other factors, it is difficult to avoid the damage of doors and windows during daily use, so how to maintain the broken bridge aluminum alloy doors and windows? 1. Adhesive strips and glass glue are the key to ensure the sealing, heat preservation and waterproofing of aluminum alloy doors and windows on the broken bridge. If they fall off, they need to be repaired and replaced in time. 2. Check the fasteners frequently, and adjust them if they are loose; for the vulnerable parts of the positioning shaft, wind brace, floor spring, etc., you can add appropriate amount of lubricating oil regularly to keep it clean and flexible; 3. During use, do not open and close vigorously. If the opening and closing is not smooth, do not force the operation. The fault should be eliminated first. Misoperation by personnel or loose fasteners is the main reason for the difficulty in opening and closing; 4. Pay attention to the maintenance of broken bridge aluminum alloy doors and windows. When cleaning doors and windows, do not step on the aluminum frame or pull the frame for support; 5. Do not use ordinary soap, washing powder, detergent powder, toilet detergent and other strong acid and alkali cleaning agents. It is recommended to use a soft cloth dampened with water or neutral detergent to wipe. After a rainy day, the raindrops on the glass and door and window frames should be wiped off in time; 6. Pay attention to the inspection of the joint between the door and window frame and the wall. If there is any looseness as time becomes longer, it is easy to deform the frame as a whole, resulting in the doors and windows cannot be closed and sealed. If the screws of the joint are loose, they should be tightened immediately. If the screw feet are loose, apply a small amount of cement with epoxy super glue to seal.

The choice of aluminum profile is really the thicker the better?

In the daily consumption process, people will have such a consumption concept: the higher the price of goods, the better, the more quantity the better, and the more materials the better...Because the more the material, the higher the corresponding price, and the natural quality The better. So, can any product be defined according to this law? When purchasing aluminum alloy profile products, the price of the profile is mainly determined by the thickness of the wall. However, consumers usually have a misunderstanding: the thicker the profile, the better? This is not the case. 　　 When many consumers buy aluminum alloy doors and windows, they will take it for granted that the thicker the aluminum wall thickness, the better the product quality will be if it exceeds the national standard. In fact, this is not the case. According to industry insiders, the national standard for product wall thickness is to ensure product safety and performance, and is set in accordance with energy conservation and environmental protection requirements. It is not that the thicker the product wall thickness, the better the product quality. Because the wall thickness of the profile is too thick, the air-tightness and water-tightness of the product cannot be guaranteed, and the quality of the product is high, which will inevitably lead to excessive waste of resources. Moreover, there are more consumables for products that are too thick than products that meet the national standard, which will inevitably bring too high product prices and bring unnecessary economic burdens to consumers. Therefore, aluminum products that meet the requirements of national standards can be called good products. 　　 Generally speaking, as long as the advertising aluminum materials produced by the regular aluminum alloy profile manufacturers are made of high-quality aluminum ingots, they have good tensile strength and yield. The thickness of the profiles strictly implements the "national standard". 　　It can be seen that the thicker the wall thickness of the aluminum alloy profile, the better. Only in compliance with the relevant national standards, the quality of the product can be well guaranteed.
