杯子磨砂对比图
目前工件的表面处理方法一般都是用喷砂抛丸两种工艺,喷砂机适用范围比较广。今天来概述一下表面处理的等级要求。

 【清理等级】

也即清洁度,代表性国际标准有两种:一种是美国85年制订“SSPC-”;第二种是瑞典76年制订的“Sa-”,它分为四个等级分别为Sa1Sa2Sa2.5Sa3,为国际惯常通用标准,详细介绍如下:     

Sa1级――相当于美国SSPCSP7级。采用一般简单的手工刷除、砂布打磨方法,这是四种清洁度中度最低的一级,对涂层的保护仅仅略好于未采用处理的工件。

Sa1级处理的技术标准:工件表面应不可见油污、油脂、残留氧化皮、锈斑、和残留油漆等污物。Sa1级也叫做手工刷除清理级。(或清扫级)   

Sa2级――相当于美国SSPCSP6级。采用喷砂清理方法,这是喷砂处理中最低的一级,即一般的要求,但对于涂层的保护要比手工刷除清理要提高许多。

Sa2级处理的技术标准:工件表面应不可见油腻、污垢、氧化皮、锈皮、油漆、氧化物、腐蚀物、和其它外来物质(疵点除外),但疵点限定为不超过每平方米表面的33%,可包括轻微阴影;少量因疵点、锈蚀引起的轻微脱色;氧化皮及油漆疵点。如果工件原表面有凹痕,则轻微的锈蚀和油漆还会残留在凹痕底部。Sa2级也叫商品清理级(或工业级)。  

Sa2.5级――是工业上普遍使用的并可以作为验收技术要求及标准的级别。Sa2.5级也叫近白清理级(近白级或出白级)。

Sa2.5级处理的技术标准:同Sa2要求前半部一样,但疵点限定为不超过每平方米表面的5%,可包括轻微暗影;少量因疵点、锈蚀引起的轻微脱色;氧化皮及油漆疵点。   

Sa3级――级相当于美国SSPCSP5级,是工业上的最高处理级别,也叫做白色清理级(或白色级)。

Sa3级处理的技术标准:与Sa2.5级一样但5%的阴影、疵点、锈蚀等都不得不存在了。

等级要求越高,喷砂机所用的磨料要求越细,软硬程度也有所不同。欢迎来电咨询13249848232李生
