铸铜注意事项
冷焊材料的使用方法:首先要处理好被修表面,千万不可以有锈和油,否则就会造成胶层脱落,进行粗化处理是最好,这样可以增加分子间的结合力,大大增强修补后的产品使用寿命。还要记住要选择铸件本身材料相对应的专用冷焊材料,例如铸铜件就要选用(劲素成)JS904铁制冷焊材料,钢、铝、铁等也要选择它们专用的冷焊材料,已达到最好的修补效果。
Usage of cold welding material: First of all, the repaired surface should be treated well, and no rust or oil should be allowed. Otherwise, the adhesive layer will fall off. Coarsening treatment is the best way to increase the bonding force between molecules and greatly enhance the service life of repaired products. It is also important to remember that special cold welding materials corresponding to the casting materials should be selected, such as JS904 iron refrigeration welding materials for copper castings and special cold welding materials for steel, aluminium and iron, so as to achieve the best repair effect.
