The standard wet sand blasting machin還行e is mainly used for small跳高 mold sand blasting:
Because of the imp銀少act and cutting effe在議ct of abrasive on the w上又orkpiece surface, the workp舊妹iece surface can o高錯btain a certain degree of cl醫報eanliness and differ日兒ent roughness, and the mechanical prope校好rties of the workp朋草iece surface can be理件 improved. Therefore, the 年們fatigue resistance of th為樹e workpiece is improved, the adhesion 個厭between the workpiece and th湖服e coating is increased, the durability又靜 of the coating is ex員船tended, and it is also conducive to the小制 leveling and decoration of長上 the coating. The impurities, vari學從egated colors and oxide layers著就 on the surface are也飛 removed, and the medium 這行surface is roug哥嗎hened, It can eliminate the r空視esidual stress of the workpiece and機計 improve the su著員rface hardness of刀事 the substrate.校生
