Sandblasted Stainless Steel Sheet

Stainless steel sandblasted finish is a new type of environmental protection material. The manufacturing process of the stainless steel sandblasting board is not simply to coat a layer of colorant on the surface of the sandblast stainless steel sheet, it can produce bright colors, even through a very complicated process. The main method used is the acid bath oxidation coloring method to form a transparent chromium oxide film on the surface of the sandblast stainless steel sheet.

After the light is irradiated, different colors will be produced due to the thickness of the film. The coloring process is carried out in a hot chromium sulfuric acid solution tank. After immersing the stainless steel sandblasting board, an oxide film of only one hundred divisions of the hair strand diameter will be formed on the surface. As time goes by and the thickness of the oxide film increases, the color of the surface of the stainless steel sandblasting board changes continuously.

When the thickness of the oxide film increases from 0.2 microns to 0.45 microns, the color of the surface of the stainless steel sandblasting board can be controlled by the soaking time to obtain the required stainless steel sandblasting board. After the hard coating treatment, stable compounds such as chromium trioxide and chromium hydroxide can be generated at the wavelength. It not only fills the small holes in the oxide film, but also improves the wear resistance, corrosion resistance, and heat resistance of the oxide film, and greatly improves the overall performance of the material.

It can resist salt spray corrosion for more than 10 years, and will not change color after more than 30 years of ultraviolet rays. The main body is integrated with the colored layer to maintain the basic structure of the original sandblast stainless steel sheet. The colored surface of the stainless steel sandblasting board has the advantages of bright colors, bright colors, colorful colors, softness, elegance, and high finish.

The surface of sandblasted stainless steel sheets is treated with a certain degree of corrosion resistance and easy cleanability, and the following cleaning methods can be used:

• Scrub with mild soapy water or neutral detergent, then rinse well with water and wipe dry.
• Use a cleaner that does not contain acid, chlorine or fluorine.
• Wipe with a soft fiber cloth or sponge and avoid using hard objects such as wire brushes to scrape the surface.
• Using a special stainless steel cleaner for cleaning will protect the surface finish of the sandblasted stainless steel sheets.

It is important to note that when cleaning sandblasted stainless steel sheets, you should avoid using too powerful cleaners or too hard cleaning tools to avoid damage to the surface.

The surface treatment of sandblasted stainless steel sheets will affect its corrosion resistance because the surface treatment will change the chemical and physical properties of the stainless steel sheets surface. Sandblasting is a mechanical surface treatment method, which makes the surface of stainless steel sheets form tiny pits and capillaries by high-pressure sandblasting, thus forming a kind of abrasive surface effect. This surface treatment method will reduce the smoothness of the stainless steel sheets surface, making its surface area increased, but also change its surface roughness. If the surface treatment of stainless steel sheets is improper or using improper cleaning methods, it may damage the surface of sandblasted stainless steel sheets and lead to corrosion, so care needs to be taken to use proper cleaning methods.

The processing difficulty of sandblasted stainless steel sheets is relatively low, and they can be processed and formed by common stainless steel processing methods, such as shearing, bending, punching, welding, etc. At the same time, because its surface texture can conceal certain processing traces, so sandblasted stainless steel sheets are more suitable for mass production.

However, for some complex processing processes, such as pattern hollowing, uneven surface treatment, etc., more advanced processing equipment and technology may be required, and the corresponding cost will be increased. Therefore, for different product requirements, the processing difficulty and cost need to be evaluated according to the actual situation to determine whether it is suitable for mass production.

The price of sandblasted stainless steel sheets may be slightly higher relative to other surface treatment methods for stainless steel sheet types because of the additional equipment and labor costs associated with the sandblasting process. In addition, prices can vary from manufacturer to manufacturer. However, for some high-end products and special needs, the aesthetic and characteristic performance of sandblasted stainless steel sheets may bring higher added value and market competitiveness.

The service life of sandblasted stainless steel sheets depends on a number of factors, such as the environment in which they are used, how they are used, and how they are cleaned and maintained. Generally speaking, if used and maintained properly, the service life of sandblasted stainless steel sheets can reach several decades. Sandblasted stainless steel sheets are corrosion-resistant, wear-resistant and easy to clean, which can reduce the frequency of cleaning and maintenance, thus extending its service life. In addition, the material and thickness of the sandblasted stainless steel sheets will also affect their service life.

The surface of sandblasted stainless steel sheets will reduce the appearance of fingerprints and other stains compared to other surface treatment methods, but they cannot be completely avoided. Because fingerprints and other stains are mainly formed by tiny substances deposited on the surface by fingers and dust in the air, care needs to be taken to keep the surface clean during use and maintenance to avoid prolonged contact and friction in order to prolong its service life and aesthetics. You can use professional cleaners or soft cloth to wipe the surface, or use some special anti-fingerprint coating and other techniques to further reduce the appearance of stains.

Sandblasted stainless steel sheets have the following advantages and disadvantages compared to other stainless steel surface treatment methods:

Advantage:

• High Aesthetics: Sandblasted stainless steel sheet surface treatment can present fine texture and silk-like luster, which increases the aesthetics and decorativeness of the product.
• Good Corrosion Resistance: Stainless steel itself has good corrosion resistance, and after the surface treatment of sandblasted stainless steel sheets, its surface is more smooth and delicate, so the corrosion resistance is better.
• Easy to Clean: Sandblasted stainless steel sheets are smoother, easier to clean, dirt, fingerprints and so on are relatively easy to leave.
• Good Abrasion Resistance: The surface treatment of sandblasted stainless steel sheets makes its surface hardness and abrasion resistance better.

Disadvantages:

• Higher Processing Difficulty: The surface treatment of sandblasted stainless steel sheets requires professional equipment and technology, which is difficult to process, so the processing cost is higher.
• Relatively High Price: Due to the special nature of its surface treatment, the price of sandblasted stainless steel sheets is relatively high compared to other surface treatment methods.
• Poor Plasticity: The texture of sandblasted stainless steel sheet is more obvious after surface treatment, and the plasticity is poor, which is not suitable for the processing methods that require bending, stretching and other deformation.
