Ladder is widely used for its durability, but to ensure safety, the processing of the surface anti-slip texture is crucial. The following are the key points of its processing technology.
First, the surface of the ladder needs to be pre-treated before processing. To thoroughly clean the oil, impurities and oxide layer on the surface, chemical degreasing agents can be used in combination with mechanical polishing. Chemical degreasing can effectively remove oil stains, while polishing can eliminate surface unevenness and oxidation marks, providing a good foundation for subsequent anti-slip texture processing. For example, using fine sandpaper to gently polish along the direction of the ladder surface texture to make the surface roughness reach a suitable range, which can not only ensure the texture processing effect, but also will not excessively damage the material.
Secondly, choose a suitable anti-slip texture processing method. Common ones are sandblasting and etching processes. Sandblasting forms a uniform pit texture by high-speed spraying sand particles to hit the stainless steel surface. Parameters such as the size, hardness and sandblasting pressure of the sand particles will affect the depth and roughness of the texture. If medium-hard quartz sand is used and sandblasting is performed at a pressure of 0.4-0.6MPa, a more ideal anti-slip effect can be obtained. The etching process uses chemical reagents or electrochemical methods to corrode textures on the surface of stainless steel. This method can accurately control the shape and depth of the texture. For example, by using acidic etching solution, the texture depth can be adjusted by controlling the etching time, and fine and regular anti-slip textures can be formed.
Furthermore, the processing link after the anti-slip texture processing cannot be ignored. The processed surface should be cleaned to remove residual sand, chemical reagents and other impurities, and then passivation treatment should be performed to enhance the corrosion resistance of stainless steel. For example, a passivator is used to form a dense passivation film on the surface to prevent the texture from rusting due to water accumulation or contamination with corrosive substances. In addition, a layer of transparent anti-slip paint can be applied to the texture surface to further enhance the anti-slip performance and protect the texture, extending the service life of the ladder.
Finally, quality inspection is the key to ensuring the effect of anti-slip texture processing. The inspection content includes the depth, uniformity, roughness and anti-slip performance of the texture. The roughness of the texture surface can be measured using a roughness meter, and the anti-slip coefficient can be detected by a friction test device that simulates human stepping. Only when all indicators meet safety standards can the safety and reliability of Ladder be guaranteed during use, providing users with stable support and anti-slip protection.
