5. Have the following basic knowledge broken bridge aluminum doors and windows:
1. How is the aluminum alloy profile of doors and windows made?
It is a profile mainly composed of aluminum and some alloy elements to enhance strength and hardness. Cast aluminum alloy can be divided into aluminum silicon alloy, Aluminum copper alloy, aluminum magnesium, aluminum titanium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition. Generally, the raw material alloy is aluminum ingot, and after aluminum ingot is melted into aluminum rod, it is extruded into doors and windows aluminum strip by heating. It is not easy to oxidize rust-resistant at normal temperature, but it will react with hydrogen. Although the process is relatively slow, however, in order to increase the service life, surface spraying anti-oxidation treatment is needed, and the service life of the treated aluminum alloy profiles is over 30 years.
2. What is Bridge-cutoff aluminum alloy profile? What are its advantages?
It is divided into two ends in the process of processing. In the middle, PA66 nylon heat insulation strip is used to connect the two ends into a whole to form a profile with heat insulation layer. The inside and outside are separated, and the inside and outside colors can be chosen arbitrarily. It can be made into two colors with beautiful appearance, good performance and energy saving effect.
3. What is the difference between ordinary aluminum alloy profiles and bridge-cutoff aluminum alloy profiles?
Ordinary aluminum profiles have a single color, the whole is a conductor, and the heat transfer and heat dissipation are relatively fast; The color of broken bridge aluminum profiles is diversified, and PA66 nylon heat insulation strips are used to connect both ends to form heat insulation layers. The temperature difference between inside and outside is different, which will not transfer heat, it plays the role of heat preservation and energy saving.

17. What is the k value of heat transfer coefficient? What is the effect? Bridge-cutoff aluminum alloy doors and windows what is the heat transfer coefficient?
K value is the term of heat transfer. In heat transfer, K value is also called heat transfer coefficient, which was previously called overall coefficient of heat transfer. The current national standards and specifications are uniformly named as heat transfer coefficient. The smaller the heat transfer coefficient K value of the enclosure structure, or the larger the heat transfer resistance R0 value, the better the heat preservation performance.
K value is the speed of internal temperature conduction through time when testing, and the heat transfer value is obtained through time and temperature. It can test the thermal insulation performance of the window profile structure. The smaller the k value, the better the thermal insulation performance.
The heat transfer coefficient of ordinary aluminum alloy doors and windows is about 3.5-5.0;
Bridge-cutoff aluminum alloy doors and windows heat transfer coefficient is about 2.5-3.0;
The heat transfer coefficient of the system aluminum alloy doors and windows is about 2.0-2.5.
