手工粗糙的

Such as angle grinder, wire brush, needle beam pneumatic rust, and wind knock rust hammers, gear-type rotary rust, etc., are semi-mechanized equipment, tools, light, mobility, and to more thoroughly to rust , old coatings, the coating can be played on the shelf hair treatment, significantly more efficient than manual derusting increased up to 1 ~ 2m2 / h, but can not remove the oxide skin, the smaller surface roughness and can not achieve high-quality surface to deal with quality, ergonomic handle lower than the jet.

如角向磨光机、钢丝刷、风动针束除锈器、风动敲锈锤、齿型旋转除锈器等，属于半机械化设备，工具轻巧、机动性大，能较彻底去除锈、旧涂层等，能对货架涂层进行打毛处理，效率比手工除锈大大提高，可达1~2m2/h，但不能除去氧化皮，表面粗糙度较小，不能达到优质的表面处理质量，工效较喷射处理低。
