要获得可靠的粘接制品,粘接表面必须是清洁的、干燥的、坚固的。如果表面预先处理不好,不能得到理想粘接效果。常用的表面处理方法分为物理和化学方法,这两种方法通常配合使用。 1.物理方法普通表面处理的物理方法分为机械加工、喷砂、砂纸打磨和钢丝刷刷法。这些方法适用于金属的粘接表面处理。其中,喷砂法是一种最佳方法,因为它能迅速除掉表层 To obtain reliable bonding products, the bonding surface must be clean, dry and sturdy. If the surface pre-treatment is not good, can not be the ideal bonding effect. Commonly used surface treatment methods are divided into physical and chemical methods, the two methods are usually used in conjunction. 1. Physical Methods The physical methods of ordinary surface treatment are divided into mechanical processing, sandblasting, sandpaper grinding and wire brushing method. These methods are suitable for metal bonding surface treatment. Among them, sandblasting is the best method, because it can quickly get rid of the surface
