冷喷锌的使用范围及操作注意事项

发布时间:2016.04.27    点击数: 217281

        冷喷锌作为一种高效重防腐材料,镀层含96%以上锌及融合料,具备镀锌及普通涂料的双重优点,提供阴极保护及屏障保护双重功能,防腐性能优异,可常温便捷施工,将“镀锌”变得如用油漆一样简单,是替代热浸锌、热喷锌的好材料。

 

        1.表面预处理重要点是露出干净的钢铁或镀锌表面。冷喷锌必须直接涂在铁或镀锌的表面上,否则没有防锈效果。如果有旧涂膜的情况下,必须将旧涂膜全部除去,否则没有防锈效果。钢铁:清除钢铁表面的灰尘,油污,尤其是沿海环境中的海盐,对于恶劣环境下或高防腐性能要求下采用喷砂除锈,达到等级ISO(SIS)Sa21/2SSPCSP-10,对于一般大气环境下或不能采取喷砂处理的使用动力工具除锈,达到等级ISO(SIS)St3SSPCSP-3.镀锌件:必须清除镀锌件表面的灰尘,油污,海盐,研磨纸等除去白锈,达到等级ISO(SIS)St2SSPCSP-2,已生锈的地方用动力工具除锈,达到等级ISO(SIS)St3?SSPCSP-3.

        2.储存含有大量的锌粉,储存期间容易产生沉淀分层,因此在开盖后必须充分搅拌.搅拌后请确认罐底无沉淀存在.同时,在涂装过程中也要注意经常搅拌,防止锌粉沉淀。

        3.涂装方法涂装方法为刷涂,辊涂,有气喷涂,无气喷涂,同时还有喷雾剂型。刷涂/辊涂:选用毛较为柔软,可以吸收大量涂料的刷子,涂装时注意不要延展涂膜,不要留下刷痕,以保证涂膜厚度,均匀。请勿稀释。有气喷涂:过滤网100目使用喷口口径为1.5~2.0㎜气压:标准0.29MPa,稀释时用专用稀释剂设定为重量的5%以下无气喷涂:过滤网50-60目使用机型GRACO大于GGO317,Basic proportioned(Recommend)30:1以上,低气雾化压力10MPa基本不需稀释。涂装时,请垂直距离涂装面约750px,涂装速度250px/秒。(每个厂家的产品不同涂装方法有区别)

        4.面漆涂装选用冷喷锌涂料作为防腐涂装体系底漆时,可以与多种后道涂料配套。(除醇酸类油性涂料外)·面漆的涂装方法建议使用喷涂或气雾剂式,刷涂或滚涂易引起涂膜表面掉漆。•由于含有大量的锌粉,冷喷锌涂膜中有很多空隙,直接上面漆时易出现气泡,可以先将50%左右被稀释的面漆涂在冷喷锌涂膜上面,以便填没表面的空隙,然后上面漆。若作为单独的防腐涂料体系时,需要上面漆。
