在之前的文章中，我们为您分析的环氧地坪出现变色的原因，今天，我们来说一说环氧地坪变色的预防吧!有哪些措施可以预防环氧地坪变色呢?环氧地坪的涂料是否需要均匀的搅拌呢?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。如含有铁蓝的蓝色或绿色漆，在储存过程中会褪色，但施工后暴露在空气中的颜料会逐渐恢复。

In previous articles, we analyzed the reasons for the discoloration of epoxy floors. Today, let's talk about the prevention of discoloration of epoxy floors. What measures can prevent the discoloration of epoxy floors? Does the paint of epoxy floors need uniform mixing? Some of the pigments in the pigments will undergo chemical changes, lose the inherent dyeing power of the pigments, and cause discoloration or discoloration. Blue or green paint containing iron blue will fade during storage, but the pigments exposed to air will gradually recover after construction. 1、环氧地坪在施工前应充分搅拌均匀。

1. The epoxy floor should be fully stirred uniformly before construction.

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。

The density of several pigments in multicolor paint is different. Heavy pigments gradually sink in storage and light pigments gradually float. If they are not stirred evenly enough, they will not match the original color after construction.

2、金属颜料应与清漆分装。

2. Metal pigments should be separated from varnishes.

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。

Metal powder pigments will turn black and green when they are stored and corroded by residual free acids in the paint.

3、酸值高的涂料不宜用铁桶包装。

3. Coatings with high acid value should not be packed in iron drums.

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。

The varnish with higher acid value is easy to react with iron packaging barrel, and the transparency of the varnish decreases and the color becomes darker.

4、根据需要选择涂料配方中的树脂和颜料。

4. Choose resin and pigments in paint formulation according to need.

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。

The light and heat resistance of some pigments in coatings are not good. Some resins have poor weather resistance and are easily yellowed when exposed to light.

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。

5. In the formulation design of coatings, attention should be paid to the absence of pigments that can react with resins or additives. It is strictly forbidden to mix two different types of coatings with mixed coloring without experimenting in construction.
