    厂家分享预防环氧地坪变色的五中方法(秘籍)

    环氧地坪漆施工调色时 严禁不经过试验,环氧地坪就随意将两种不同类型的涂料搭配混合调色使用。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。环氧地坪在使用的过程中出现变色是一个很常见的问题,但这将严重影响环氧地坪的外观质量,所以当出现此类问题时,环氧地坪一定要及时解决。作为专业的环氧地坪施工厂家,我们这就来为大家介绍几个预防环氧地坪变色的几个技巧:

    It is forbidden to mix two different types of epoxy flooring paint with mixed color without experimenting in the construction of epoxy flooring paint. Some pigments will undergo chemical changes, lose the inherent dyeing power of the pigments, and cause fading or discoloration. Blue or green paint containing iron blue will fade during storage, but the pigments exposed to air will gradually recover after construction. The discoloration of epoxy flooring is a common problem in the use process, but it will seriously affect the appearance quality of epoxy flooring, so when such problems arise, epoxy flooring must be solved in time. As a professional manufacturer of epoxy floor construction, we will introduce some techniques to prevent the discoloration of epoxy floor. 

    1、根据需要选择涂料配方中的树脂和颜料

    1. Selection of resins and pigments in paint formulations according to needs

    涂料中个别颜料的耐光和耐热性不好,环氧地坪有些树脂耐候性较差,遇到光易变黄。

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

    2、金属颜料应与环氧地坪漆分装

    2. Metal pigments should be separated from epoxy floor paint

    金属粉末颜料在储存中,受环氧环氧地坪中残存游离酸的腐蚀,将会发乌变绿。

    Metal powder pigments will turn black and green in storage due to the corrosion of residual free acids in epoxy floors.

    3、环氧环氧地坪在施工前应充分搅拌均匀

    3. The epoxy floor should be fully stirred and even 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.

    4、酸值高的环氧地坪漆不宜用铁桶包装

    4. Epoxy floor paint 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.

    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

    5. In the formulation design of coatings, attention should be paid not to the use of pigments that can react with resins or additives.
