Photovoltaic

Offshore photovoltaic support is an important support structure for offshore power generation systems, and its anti-corrosion performance and service life are very important. Common offshore photovoltaic support materials are carbon steel, stainless steel and aluminum alloy. The Marine environment is extremely corrosive to photovoltaic supports, including factors such as seawater, salt spray, humid air and ultraviolet light. This corrosion environment is 55 times faster than that of the dry northwest of China.

Industry BackgroundRequirement Analysis

  • Driven by the national low-carbon strategic objectives, offshore PV has a broad development prospect, but the anti-corrosion and anti-fouling of PV mounts is a difficult and painful point in the industry.

  • Traditionally, hot-dip galvanising produces high levels of zinc salts in harsh environments and gradually fails. Simultaneous attachment of organisms results in increased facility loading and accelerated corrosion.

Product ApplicationCore Requirements

  • Excellent chemical resistance, acid and alkali resistance, corrosion resistance and salt spray resistance. The hardness of the product is high, and it can reach 4H under baking conditions, which can meet the higher scratch resistance requirements.

  • Durable adhesion and stain resistance, outdoor long-term exposure after the adhesion and stain resistance index to maintain normal values, good maintenance. Resin high solid and low viscosity product features, low product viscosity, less solvent added to the construction, is an environmentally friendly product, can provide more than 15 years of protection requirements in C5 outdoor harsh environment.
