在日常的石材生产工作中,会有很多初入石材行业的工作者弄不清楚,为何有些石材不管怎么抛光都无法抛亮,遇到这种问题只能干着急,不知该如何处理,所以今天小编就为大家来初步分析下导致抛不亮的几种因素,希望能都对各位石材工作者有所帮助。 抛光灰色大理石实例图片 1.刚翻新过的石材 刚翻新过的石材,是初始结晶,表面第一次与酸性物质(结晶剂的主要成分)发生反应,属于活跃状态。刚研磨过的石材表面处于相对粗糙状态,需要较强的化学刻蚀作用使表面达到相对光滑,同时对填补与微填补的需求较大。所以刚翻新过的石材需要较大量的结晶材料。 2.材质疏松的石材 材质疏松的石材相对来说钙质含量较低,需要的化学刻蚀作用比较强,需要大量的结晶剂填补,加上结构疏松,结晶剂容易渗入石材内部,不能留在石材表面发生反应,结晶材料一抛就容易被吸干。 3.含钙量低的石材 含钙量低的石材,需要大量的结晶材料与之发生充分反应,出光比较慢,也比较难。 4.石材是否干净干燥 石材干净干燥是抛光的必要因素。同一块石材,使用结晶剂抛光,推尘后抛光比不推尘抛光光泽度可高3度左右。石材潮湿的情况下使用钢丝棉抛光,石材容易发乌。 5.抛磨过度 抛磨过度造成温度升高太快,石材刚达到最佳出光温度又随着温度上升迅速失光了。 6.干磨后石材温度过高 石材干磨后不能立即做抛光,需要等到石材温度降至常温后再做结晶抛光处理,过高的温度会造成药剂很快挥发以及抛磨失光的问题。 7.施工面积、机器的重量、转速等,也会影响石材出光。 工程面积比较大的情况下,由于温度不均匀,结晶抛光的整体效果不如小面积施工。一般结晶抛光的机器重量60kg到80kg 、转速在175 转到200转的速度为宜,超过这个速度与重量,抛光过程中瞬间产生的温度过高,不利于石材出光。 看完以上总结的这些石材相关无法抛光的问题,各位对如何抛光石材应该会有一个相对全面的了解,就可以对症下药,选择适合自己抛光石材的方法了。 文章链接来源www.slfsy.com
