环氧地坪的变色是如何预防的?
作者:管理员    发布于:2012-12-31 14:18:00    文字:【】【】【

  施工单位在建设环氧地坪的时候会根据周围的环境,从而选出适当的色浆进行搭配,使其在颜色上能有效地融入周围的环境。虽然环氧地坪搭配了颜色能使其变得更加美观,但是如果不合理的使用,就会出现变色现象,影响其美观度。那么一般施工人员是如何预防变色现象的出现呢?

  1.施工之前应该充分搅拌色漆

  施工当中运用到的色漆可能是多种的,因此就需要人们的充分搅拌,使其变均匀。目前,每种色漆的密度是不同的,在存储当中重质颜料会下沉,轻质颜料则会上浮,如果不搅拌均匀,施工后的颜色跟实际的颜色不匹配,从而影响其美观度。

  2.金属颜料和清漆要分开装

  金属颜料如果跟清漆装在一起,那么就容易污染清漆,使其变得不能使用。因为金属粉末在颜料当中容易受残存的游离酸的腐蚀,从而变绿,较终影响清漆。

  3.酸值高的涂料不应该用金属容器存放

  一般酸值比较的清漆不应该存放在金属容器当中,如铁桶。因为游离在清漆当中的酸会跟金属发生反应,从而降低清漆的透明度,使其颜色变深。因此,酸值高的清漆较好存放在塑料容器当中。

  4.在施工之前进行配置颜料

  目前,色漆当中的个别颜料的耐光性和耐热性非常的不好,容易出现遇光变色。因此,较好在使用之前进行调配,或者放弃该颜料不用。

  做到上述的方法,那么就会大大减少出现环氧地坪变色的现象。
