First, the mesh number of brushing is a key parameter. The higher the mesh number, the finer the scratches on the surface, the finer and smoother the texture, presenting a delicate visual effect, and is often used in anti-theft nets for high-end residential or commercial places. On the contrary, when the mesh number is low, the scratches are coarser, which will create a rough and rustic texture, suitable for some industrial or retro style buildings. From the perspective of corrosion resistance, the finer brushed surface has shallow and uniform scratches, which is not easy to accumulate water and hide dirt, and to a certain extent reduces the contact area and residence time between the corrosive medium and the metal surface, thereby helping to improve corrosion resistance; while the coarser brushed surface may have deep and wide scratches, making it easier for the corrosive medium to penetrate into the metal, and the corrosion resistance will be relatively weaker.
Secondly, the direction of brushing will also have an impact. One-way drawing can make the light form regular reflections on the surface, enhance the visual sense of lines and three-dimensionality, and make the anti-theft net look more regular and orderly. Two-way cross drawing will create a unique grid-like light and shadow effect, increasing the layering and complexity of the surface. In terms of corrosion resistance, one-way drawing is more likely to slide down the drawing direction due to impurities such as water flow and dust, reducing the possibility of local water accumulation and dirt accumulation. In contrast, the surface of two-way cross drawing may form some tiny grooves at the intersection, which is easy to retain impurities and has a certain negative impact on corrosion resistance, but if regular cleaning and maintenance are done, this effect can be effectively controlled.
Furthermore, the pressure and speed parameters during drawing are crucial. Appropriate pressure and speed can ensure the depth and uniformity of drawing. Excessive pressure or too fast speed may cause uneven drawing and scratches of varying depths, which not only affects the texture, but also these uneven places may become the starting point of corrosion, because deeper scratches are more prone to local corrosion. The uniform wire drawing surface produced under the appropriate pressure and speed parameters can form a relatively stable oxide film, which helps to improve the corrosion resistance of stainless steel and make it better resist oxidation and corrosion in daily environment.
In addition, the lubricant used in the wire drawing process should not be ignored. High-quality lubricants can reduce the friction between the wire drawing tool and the stainless steel surface, prevent the high temperature generated by friction from causing changes in the surface structure of the material, thereby ensuring the original corrosion resistance of the material. At the same time, lubricants can also play a certain cleaning role, taking away the debris and impurities generated during the processing, and preventing them from remaining on the surface and affecting corrosion resistance and texture.
Considering environmental factors, different use environments have different requirements for wire drawing process parameters. In humid and salty coastal areas, priority should be given to process parameters with higher mesh counts, wire drawing directions that are conducive to drainage, and precise pressure and speed control to enhance the corrosion resistance of anti-theft nets; while in dry and clean inland areas, on the premise of ensuring basic texture requirements, some parameter requirements can be appropriately relaxed, focusing on improving processing efficiency and reducing costs.
The process parameters of stainless steel products anti-theft net processing surface brushing affect its texture and corrosion resistance in many aspects. In the actual processing process, it is necessary to comprehensively consider factors such as aesthetic requirements, use environment and cost, and reasonably select and optimize process parameters to ensure the production of stainless steel products anti-theft net processing products with both good visual effects and reliable corrosion resistance to meet the needs of different customers and application scenarios.
