Hongwang Group holds patents of the coil finishing technology of brushed, 8K, Ti-Black, Ti-Gold, PVD coating and AFP. Comparing with the traditional single sheet finishing technology, coil finishing has the advantage of high efficiency, stable quality and lower production cost. The large-scale production has become the solution of the two most intractable issues: color difference and low efficiency of single sheet processing. Coil finishing technology greatly improved color stability and quality controllability.
Basic Surface Treatment of Decorative Ss Coil And Sheet
After multiple grinding and polishing processes, the surface of the stainless steel plate achieves a mirror-like effect with extremely high gloss and reflectivity. This treatment method has high requirements for the process and can highlight the metal texture and high-end quality of the stainless steel plate.
Use grinding tools such as sand belts and wire brushes to perform directional friction on the surface of the stainless steel plate to form a continuous texture with a certain direction. Depending on the grinding tools and processes, it can be divided into a variety of effects such as straight wire patterns and random wire patterns. Brushed treatment can cover up minor scratches and flaws on the surface, increase the texture and friction of the surface, and reduce the adhesion of fingerprints and stains, making the stainless steel plate easier to clean and maintain.
Use compressed air to spray sand particles at high speed onto the surface of the stainless steel plate to form a uniform rough surface effect on the surface. The surface of the stainless steel plate after sandblasting presents a matte texture, which has a unique decorative effect, while increasing the surface roughness and improving the adhesion with coatings, adhesives, etc. Different types of sand and spraying pressure can produce sandblasting effects of different coarseness and fineness.
