The white aluminum flashing roll is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage. It is a flexible building material that can be rolled into rolls, as a non-leakage connection between the engineering foundation and the building.
1. Water resistance
Water resistance means that its performance is basically unchanged under the action of water and after being soaked by water, and it has water impermeability under the action of pressure water.
2. Temperature stability
Temperature stability refers to the performance of non-flowing, non-foaming, non-sliding at high temperature, and non-brittle cracking at low temperature, that is, the ability to maintain the original performance under a certain temperature change. It is often expressed by indicators such as heat resistance.
3. Mechanical strength, elongation and fracture resistance
It refers to the performance of the color coated aluminum coil without breaking under a certain load, stress or certain deformation. It commonly uses these indicators like tensile force, tensile strength and elongation at break.
4. Flexibility
Its flexibility refers to the performance of maintaining flexibility under low temperature conditions. It is very important to ensure easy construction and no brittle fracture. The commonly used indicators are flexibility and low temperature bendability.
5. Atmospheric stability
Atmospheric stability refers to the ability to resist erosion under the long-term comprehensive action of factors such as sunlight, heat, ozone and other chemically erosive media. The commonly used indicators are aging resistance and heat aging retention rate.
At present, the amount of prepainted aluminum coils in my country is increasing year by year. It has the characteristics of low density, long service life, beautiful and smooth appearance. Haomei Aluminum has rich colors, especially white aluminum coil.
In order to make good use of color-coated aluminum coils and prolong its service life, there are certain requirements for the storage environment of aluminum flashing roll stock. First of all, make sure that the storage environment must be ventilated and dry. Aluminum coil is a non-ferrous metal alloy. If it is in contact with water, it will undergo oxidation reaction, which will damage the protective film on the surface and affect its quality.
The second is the tightness of the packaging. Generally, aluminum coils will be packaged in waterproof packaging with moisture-proof agents when they leave the factory. The packaging is suitable for long-term storage.
