With the increasing demand for solar water heaters around the world, a pre-coated aluminum sheet that can absorb solar energy and reduce reflections, to increase the efficient use of solar energy by solar water heater tubes, has become a requirement of solar water heater manufacturers, especially at high latitudes and Solar water heaters are used in high altitude areas such as high altitudes. The heat-absorbing color-coated aluminum sheet has good weather resistance and heat absorption effect. Therefore, the product can be used in the solar water heater back plate application effect is remarkable from Henan signi aluminium.
The endothermic color-coated aluminum sheet is made of high-grade aluminum plate, which is coated by continuous passivation and coating process and special performance coating. The primer is applied to the surface of the aluminum sheet with a rubber roller to make it adhere well. Sexually, the special performance coating is applied to the aluminum substrate, and the heat absorption effect of the coating is unchanged after high temperature curing.
The endothermic color-coated sheet can be widely used in solar-related products, and can utilize solar energy as possible. It is a novel, environmentally-friendly and energy-saving new material with broad market prospects.
