The appearance of color steel plate metal curtain wall decoration provides a broad stage for the development of building curtain wall. Colored stainless steel sheet metal curtain wall refers to the building curtain wall whose curtain wall panel is made of stainless steel metal sheet.
The halftone corrosion imaging process of etched flowers on the stainless steel pen barrel and pen sleeve, the method is to take a negative film with a continuous pattern and remake it with a screen to become a halftone negative film composed of dots, and cover the negative film on the photosensitive film. Stainless steel pen holder, pen sleeve, and then insert it on the rotatable shaft core to rotate exposure. After developing, it is etched to 0.02~0.03mm with ferric chloride solution at room temperature, then plated with black or white chrome, and coated with glossy paint. The stainless steel surface is coated with a photosensitive film, and then covered with a patterned negative film, exposed to light, and then developed, that is, a patterned etching film is formed on the stainless steel, and then etched in an etching solution to achieve the desired etching effect.
