导读：醇溶无机富锌底油漆对基面的要求十分高，要求钢板基面需要喷砂除锈处理，表面粗糙度和除锈都必须达到标准后再进行接下来的涂刷。那么，醇溶无机富锌底油漆的基面处理该如何处理呢？

　　Takeaway: the bottom of the alcohol soluble inorganic zinc-rich paint on the base surface is very high, for steel plate base need sandblasting derusting processing, surface roughness and cleaning must be up to standard to follow after brushing. So, how do you deal with the base processing of the inorganic zinc bottom paint?

　　醇溶无机富锌底油漆涂刷钢材抛丸预处理

　　1、 磨料：抛丸磨料必须按比例棱角砂和钢丸各自百分之五十的混合物

　　Abrasive: it must be 50 percent of the mixture of angular sand and steel balls

　　2、 表面粗糙度：达到Ry：40-80um

　　Surface roughness: to reach: 40-80um

　　3、 除锈等级：ISO8501-1标准中的Sa2.5级

　　Scale of rust removal: the Sa2.5 level in the iso8501-1 standard

　　4、 表面清洁度：≥ISO8502-3标准的3级；可溶解含量≤30mg/㎡

　　Surface cleanliness: 3 levels of the iso8502-3 standard; The content of soluble acuities were 30 mg / ㎡

　　醇溶无机富锌底油漆喷丸砂处理

　　1、 要达到现场检查娇艳必须整体达到ISO8501-1标准中的Sa2.5级，表面粗糙度：达到Ry：40-80um才能够通过。

　　1, to meet the on-site inspection, the quality must meet the Sa2.5 level of the iso8501-1 standard, surface roughness: up to the rry: 40-80um.

　　2、 局部小面积残留锈点和氧化皮需要手提式微型针孔喷砂处理。

　　2, the area of small area residual rust point and oxide skin need portable micro-needle hole blasting treatment.

　　3、 喷砂磨料的选择：常规磨料，但要满足处理后的粗糙度要求。颜料需盐分检测，达到符合标准要求。

　　The choice of abrasive abrasive: conventional abrasive, but to meet the roughness requirement after treatment. The pigment must be tested for salt to meet the standard requirements.

　　4、 表情清洁度，彻底除尘吹灰表面不允许有油和油脂等污染物存在，表面清洁度：≥ISO8502-3标准的3级，交验时才能够完整通过。
