Etched stainless steel sheet is a decorative stainless steel sheet that forms a specific pattern, texture or text on the surface of stainless steel through a special corrosion process. Here are the details for you:
previous preparation
Plate selection: First of all, we must choose the appropriate stainless steel plate according to the specific needs, common 201, 304, 306 and other types of stainless steel, different models in corrosion resistance, strength and other aspects of differences. For example, 304 stainless steel has good corrosion resistance and is often used in indoor and outdoor decoration and other occasions with high durability requirements.
Surface treatment: The early surface treatment of the selected stainless steel plate, usually including grinding, polishing and other operations, the purpose is to make the surface of the plate smooth, so that the subsequent corrosion process can be uniform. For example, by mechanical grinding to remove scratches, oxide layer and other defects on the surface of the plate, so that the surface to achieve the appropriate roughness.
Plate making and coating resist
Plate making: According to the design requirements to produce with the need to corrode the pattern, text and other content of the template. The stencil can be a film output after computer design, or it can be a rubber stencil made by hand engraving.
Coating resist: The resist is evenly coated on the surface of the stainless steel plate. There are many types of resist, such as photosensitive adhesive, wax, etc. Then the produced template is tightly fitted on the surface of the plate coated with corrosion inhibitor to ensure that the pattern and text on the template accurately correspond to the part of the plate that needs to be corroded.
Corrosion treatment
Chemical corrosion fluid selection: Commonly used chemical corrosion fluid are acidic corrosion fluid (such as hydrochloric acid, nitric acid, etc., mixed in a certain proportion) and alkaline corrosion fluid (such as sodium hydroxide solution, etc.). The corrosion speed and effect of different corrosive fluids on stainless steel are different, and the appropriate corrosive fluids need to be selected according to the specific design requirements and stainless steel material.
- Corrosion process: The stainless steel plate coated with resist and fitted to the stencil is put into the corrosive liquid, so that the corrosive liquid reacts with the stainless steel surface part that is not protected by the resist, so as to corrode these parts and form the corresponding pattern, text and other effects of the stencil. In the corrosion process, it is necessary to control the concentration, temperature, corrosion time and other parameters of the corrosion liquid to ensure the accuracy and uniformity of the corrosion effect. For example, too high a temperature may cause the corrosion rate to be too fast, making the edges of the pattern unclear; If the corrosion time is too long, it may cause excessive corrosion and destroy the effect of the original design.
post processing
Removal of the resist: After the corrosion is completed, the resist on the surface of the plate needs to be removed, and the organic solvent (such as acetone, etc.) is usually used for cleaning to restore the surface of the plate to a relatively pure state.
Surface finishing: Further finishing treatment of the surface of the corroded plate, such as grinding, polishing, etc., to eliminate some rough and uneven phenomena that may occur during the corrosion process, so that the surface of the plate is more flat and smooth, and the pattern and text formed by corrosion can also be fine-tuned to make it more perfect.
Appearance characteristic
Variety of patterns and textures
Can make a variety of patterns, such as flower patterns, geometric patterns, animal patterns, etc., as well as a rich variety of texture effects, such as frosted texture, brushed texture, imitation marble texture. These patterns and textures can meet different design needs, adding rich visual effects to architectural decoration, interior design and other fields.
Unique visual texture
Because it is formed by the corrosion process, its surface presents a unique visual texture, which is obviously different from the patterns formed by traditional printing and stickers. The pattern formed by corrosion looks more threedimensional and deep, has a unique artistic charm, can attract people's attention, and can play a good visual focus role in decorative applications.
Good corrosion resistance
Stainless steel itself has excellent corrosion resistance, after the etching plate production process, although the surface has been corroded, but because it is only local corrosion and subsequent corresponding treatment measures, it still maintains good corrosion resistance, can be used in indoor and outdoor environments for a long time, will not easily rust, fade, etc.
High strength and durability
Stainless steel itself has a high strength, after the etching plate production process, its physical properties are not significantly affected, still able to withstand a certain amount of pressure, tension and other external forces, with good durability, suitable for making a variety of long-term use and withstand a certain amount of external forces of decorative parts, such as building exterior decorative panels, indoor furniture parts.
Easy to process
Based on the machinability of stainless steel, stainless steel etched plate can be cut, bending, welding and other conventional processing operations, convenient in architectural decoration, indoor applications. For example, when making decorative panels for building exterior walls, stainless steel etched panels can be precisely cut and bent according to design requirements to adapt to the shape and layout of building exterior walls.
Architectural decoration: Often used in building exterior wall decoration, curtain wall, ceiling, stair handrails and other parts, through its unique patterns and textures to add artistic atmosphere and unique visual effects to the building. For example, some high-end office buildings, hotels and other buildings will use stainless steel etched plates to improve the appearance of the building quality.
Interior design: It can be used for the production of elevator decoration, furniture, cabinets, screens, partitions, etc., and its diverse patterns and textures can create a stylish and elegant atmosphere for the interior space. For example, when making an indoor screen, the pattern effect of the stainless steel etched plate can be used to increase the visual appeal of the screen.
Crafts production: can also be used to make a variety of crafts, such as stainless steel etching plate ornaments, pendants, etc., its unique visual texture and pattern effect makes it attractive in the crafts market.
