Mirror Polished Aluminum Sheet for Solar Reflector

Publish: Modify: Jul 28, 2021Author: From:  Haomei

The highly reflective mirror polished aluminum sheet launched by Haomei is widely used as the solar reflector material. What are its reflectivity and other advantages? Learn more.

In addition to glass mirrors and mirrors based on reflective film technology, mirror polished aluminum sheet is also one of the mirrors used in solar thermal power stations or medium- and high-temperature solar thermal utilization projects.

The highly reflective mirror aluminum launched by Haomei is one such product. It is a kind of mirror anodized aluminum. Through the vacuum magnetron sputtering process and the German continuous roll-to-roll vacuum coating equipment, based on the electronic evaporation of aluminum technology, a layer of metal aluminum is plated on it as a reflective layer.

And then a protective layer of titanium dioxide and silicon dioxide is plated on it to form a highly reflective specular aluminum material with a reflectivity of up to 95%±1%. The width of the highly reflective mirror aluminum sheet is less than or equal to 1250mm, and the thickness is between 0.3mm and 1.0mm. They are packaged in rolls for easy transportation, the mirror surface is covered by a plastic film to protect the mirror surface from damage.

CSP glass mirrors usually have a thickness of 4mm and are heavier. If mirror aluminum with a thickness of 0.8mm is used, its weight should be at least 3 times lighter than glass mirrors (according to alumina density 3.965g/cm3 and glass density 2.8g /cm3).

Even if the weight of the backplane is added, taking the high-density polyurethane material as an example, the overall weight of the reflector is lighter than the pure glass reflector. The weight reduction can reduce the investment of the bracket system, thereby bringing about the cost reduction of the overall light field system.

In addition, this mirror aluminum sheet is flexible and elastic, which can be bent up to 90 degrees without damage. For Fresnel photothermal projects or tower projects, the use of this mirror aluminum can more easily produce a micro-arc effect by mechanical external force.
