球墨铸铁管冷焊材料的使用:首先要处理好被修表面,千万不可以有锈和油,否则就会造成胶层脱落,进行粗化处理是好,这样可以增加间的结合力,大大增强修补后的产品使用寿命。还要记住要选择球墨铸铁管铸件本身材料相对应的专用冷焊材料,例如球墨铸铁管铸铁件就要选用(劲素成)JS902铁制冷焊材料,钢、铝、铜等也要选择它们专用的冷焊材料,已达到好的修补效果。会不会生锈,关键在于球墨铸铁管的工艺是否做到位了。合格的球墨铸铁管要求内衬标准厚道水泥;管子外壁要求进行喷锌处理和沥青漆涂覆,也可以选择好环氧树脂漆等。这些问题关系到球墨铸铁管在市场中效益问题,我们所不是很明白的问题,在这个时候,也将会有所了解的。很多的时候,太多的问题,是我们所忽略的,忙了很多的时候,才会发现,根本的问题本来就是很简单的。
