    环氧树脂地坪变色如何去预防?
    来源:http://www.jndmzp.com   时间:2018-4-24 16:07:47
    由于在对环氧地坪进行施工时采取了不正确的操作方法导致了环氧地坪会出现变色的现象,现在就对其变色的预防进行简单的总结。
    Because of the incorrect operation method used in the construction of epoxy floor, the phenomenon of discoloration of epoxy floor will appear, and the prevention of its discoloration is briefly summarized.
    1、环氧地坪在施工前应充分搅拌均匀。复色漆中几种颜料的密度不同,在储存中重质颜料逐渐下沉,轻质颜料逐渐上浮,使用时如不充分搅拌均匀,施工后会和原色不符。

    1, epoxy floor should be fully stirred before construction. The density of several pigments in the color paint is different. The heavy pigments are gradually sinking in the storage, and the light pigments are gradually floating. If they are not fully stirred in use, the pigment will not match the original color.

    2、金属颜料应与清漆分装。金属粉末颜料在储存中,受漆中残存游离酸的腐蚀,将会发乌变绿。
    2 and metal pigments should be separated from varnish. Metal powder pigments in storage will suffer from the corrosion of free acid in paint and will turn black to green.
    3、酸值高的涂料不宜用铁桶包装。酸值较高的清漆容易与铁质包装桶发生化学反应冒失清漆透明度降低,颜色变深。
    3, high acid value of the paint should not be packed in iron barrels. The varnish with high acid value is easy to react with the iron packing barrel. The transparency of the varnish is reduced and the color becomes darker.
    4、根据需要选择涂料配方中的树脂和颜料。涂料中个别颜料的耐光和耐热性不好,有些树脂耐候性较差,遇到光易变黄。
    4, select the resin and pigment in the coating formula according to the need. Some of the paints are light resistant and heat-resistant, some of them are poor in weatherability and light yellow.
    5、在涂料配方设计时应注意不能使用能与树脂或助剂发生化学反应的颜料。在施工调色时严禁不经过试验,就随意将两种不同类型的涂料搭配混合调色使用。料中部分颜料会发生化学变化,失去颜料固有的着色力,引起褪色或变色。
    5, attention should be paid to the use of pigments that can react with resins or auxiliaries in the formulation design of coatings. It is strictly forbidden to mix and mix different types of paints without mixing them. Some of the pigments in the material will change chemically, losing the inherent coloring power of the pigment, causing discoloration or discoloration.
