Aluminum plate is a common material in our daily life, at present, the quality of aluminum plate production is also constantly developing and improving, widely used in various industries. However, when we use aluminum plates, we always find that the surface of aluminum plates will be scratched, so what are the factors that lead to the surface scratch of aluminum plates?

1, swing the bed artificially drag aluminum plate caused by abrasion; The aluminum plate is damaged due to the excessive speed of the fork rod when the profile is transferred from the discharge track to the swing bed.

2. The mold cavity or work belt has debris, and the hardness of the mold work belt is low, so that the surface of the work belt is injured and scratched during extrusion.

3. There are hard inclusions in the exposed metal or graphite strips on the discharge track or swing bed, which cause scratches on the profile surface when it comes into contact with the aluminum plate.

4, in the transportation process between the aluminum plate friction or extrusion caused by damage. In addition, during the transportation process, if the aluminum plate packaging is not good, it will also hurt its surface.

When there is a large number of segregation surfaces on the surface of the aluminum plate and the aluminum plate is not homogenized or the homogenization effect is not good, there is a certain number of hard metal particles in the aluminum plate. When the metal flows through the work belt during the extrusion process, these segregation surfaces or hard metal particles are attached to the surface of the work belt or cause damage to the work belt, and will also cause scratches to the surface of the aluminum plate.

What are the functions of aluminum plate for external wall insulation?

Aluminum plate is a product widely used in various industries, many construction industries will also use aluminum plate to apply to external wall insulation, especially in the northern region of China, insulation is particularly important. The aluminum veneer used in the exterior wall is in line with the development trend of low-carbon life, energy saving and environmental protection, and its installation effect, beautiful and generous, many high-end decoration in favor of this new type of decorative materials. So, what are the functions of aluminum plate for external wall insulation?

1, can well meet the requirements of energy conservation in the northern region, significantly improve the comfort of living and indoor thermal stability.

2. The moisture condition of the wall is improved. In order to prevent condensation, the internal insulation layer needs to be set up an air layer, and there is no need to set up an air layer when using external insulation, and the insulation material will not be damp under the protection of the exterior curtain wall layer. At the same time, the external insulation layer increases the temperature of the entire wall of the structural layer, reduces its humidity, and thus improves the insulation performance of the wall.

3, conducive to improving the quality of the room temperature environment. Due to the large heat capacity of the internal solid wall, after the additional insulation layer on the outside of the wall, the indoor temperature change is slowed down, and the room temperature is more stable, which is conducive to energy saving, and in the summer, the external insulation material can reduce the transfer of solar radiant heat and the influence of outdoor high temperature, so that the building is warm in winter and cool in summer.

4, aluminum plate manufacturers can increase the convenient area of the house, and the shoulder effect increases the indoor use area by nearly 1% compared with the internal insulation technology.

5, the curtain wall keel connection is reliable and reliable, especially suitable for high-rise buildings, construction is not affected by the season, easy to operate, to solve the problems of wall cracking, hollow drum and other problems caused by wet external insulation operations in the past, and the keel and embedded parts of the building are beautiful in appearance, and the fasteners are basically standard parts of the composite aluminum plate is an industrial product, and the insulation material is a fixed quality.
