The old etching technology, using high concentration strong acid corrosive solution, discharges a large amount of acid waste water, waste gas, waste residue in the production process, and the environmental protection risk and environmental protection disposal cost are higher and higher; Now, the national environmental protection policy is more and more stringent, facing huge environmental pressure, so it is imperative to improve the product performance and meet the environmental protection requirements of process application. The nano particle coating process is pollution-free, in line with the national environmental protection policy, conform to the trend of industrial environmental protection, and greatly save the cost of environmental protection disposal.

Based on the products of Hongliang have absolute advantages in technology, production cost, energy conservation and environmental protection, combined with the advantages of the management team, it is expected to gradually replace the existing traditional etching process products in the next three to four years, which is also in line with the requirements of the national 14th five year plan for green environmental protection development.
