Is solar anodized better than black chrome or blue film?

It must be said that these types of heat absorbers each have their own advantages and disadvantages. We can't just say which one is better, there are several differences, and it depends on which one the user prefers. In terms of total heat absorption, since blue film has the lowest emissivity, it absorbs more heat than anodized and black chrome, but the difference is not very big. From an environmental point of view, blue film is produced by magnetron sputtering. There is no waste water or gas emissions. In comparison, anodizing and black chrome plating both produce a large amount of wastewater containing a large amount of heavy metal ions. the production process is very inconvenient. In terms of price, anodizing and black chrome are relatively cheap, and blue film is slightly more expensive. However, with the launch of the blue film by Shenzhen Chunhui Solar Energy Company, the price of some blue films on the market has become lower than that. black chrome. In terms of salt spray corrosion resistance, black anodized and chrome-plated films are better than blue films, but the blue film produced by Shenzhen Chunhui Solar has made breakthroughs in salt spray resistance, without corrosion for more than 36 hours, inside a good flat plate. collector No problem keeping it in service for decades. I hope the answer is useful to you!
