Sand surface treatment of aluminum sheet sand blasting method: with ore sand or river sand; aluminum plate brush sand method sand surface treatment: round copper wire brush rotation, the following conveyor belt on the side of aluminum plate on the side left and right side string to get the sand surface; aluminum plate grinding method sand surface treatment: the offset plate machine is eliminated with the same plate, just to continuously add water rinse, you can get meticulous Good gloss sand surface effect; aluminum sheet chemical sand surface treatment: the chemical sand surface treatment agent, through chemical treatment, get the effect of the sand surface aluminum plate, the aluminum sheet is fine and uniform.
选用厚度为1mm以上的铝板，若铝板过薄，则喷砂后容易变形。喷 砂处理前铝板表面要进行除脂处理，并用细木炭磨去其表面上的任何划 痕，然后用粒度为70-90的沙子，在6kgmm2的压力下，用喷枪均匀地喷射铝板表面，保证喷砂均匀。然后铝板再进行化学抛光处理。喷砂工 艺的缺点是有粉尘污染，应该有良好的除尘装置。使用铜丝刷轮，以1500min的速度转动，铝板安装在刷轮下面的工作台上，刷砂时铝板缓慢向前移动，同时左右窜动，经过铜丝刷的刷磨，使铝板表面呈磨砂效果。
If the thickness of the aluminum plate is more than 1mm, if the aluminum plate is too thin, it will be easy to deform after sandblasting. Before the spray treatment, the surface of the aluminum sheet should be treated with degreasing, and any scratches on the surface of the surface are worn out with fine charcoal. Then the surface of the aluminum plate is evenly sprayed with a spray gun under the pressure of the particle size of 70-90. The surface of the aluminum plate is evenly sprayed with a spray gun, so as to ensure that the sand is evenly sprayed. Then the aluminum plate is then chemically polished. The disadvantage of sandblasting is dust pollution, and there should be a good dust removal device. The copper wire brush wheel is used to rotate at the speed of 1500min. The aluminum plate is installed on the working table under the brush wheel. When the sand is brushed, the aluminum plate moves slowly forward and moves around the same time. Through the brush grinding of copper wire, the surface of the aluminum plate is sanding.
使用胶印制平凹版的磨版机，用金刚砂或钢球加适量水对铝板进行 磨砂处理。磨好后用清水清洗干净、晾干，然后再进行化学抛光。这种 方法可以代替喷砂处理。也有采用通常的流水方法进行磨砂，磨砂后不 用进行化学抛光就能得到银白色的光泽均匀、精细的砂面，可制作仪表盘D。目前国内外均有生产铝板砂面处理用的化学砂面剂，铝板经过化学砂面剂的处理产生砂面效果。这种方法使用的铝板要求质量比较高，晶 粒比较均匀细致。
四川11选5 Using the offset printing gravure plate grinding machine, we use abrasive or steel ball to add aluminum to the aluminum plate. After grinding, rinse and dry with clean water, then do chemical polishing. This method can replace sand blasting treatment. There is also the use of ordinary water method for grinding, after grinding without chemical polishing can get a silver white gloss uniform, fine sand surface, can make the instrument panel D. At present, both domestic and foreign chemical surface agents for producing aluminum plate and sand surface are treated, and the effect of sand surface is produced by aluminum sheet after chemical sand treatment. The aluminum plate used in this method requires high quality and uniform grain size.
