With the improvement of people's appearance requirements, people's requirements for the epoxy floor of parking lot are no longer just for durability, but also put forward higher requirements for its appearance. In the future application process, the epoxy floor will not show fading, discoloration and other issues. It is almost impossible to remain ambitious in the real environment. Even so, it is still necessary to make good preparations for the fading of epoxy flooring and extend its service life as far as possible. This is to introduce a few tips for preventing the color change of epoxy floor. 根据需要挑选涂料配方中的树脂和颜料，涂猜中单个颜料的耐光和耐热性欠好，有些树脂耐候性较差，遇到光易变黄。金属粉末颜料在贮存中，受环氧地坪中残存游离酸的腐蚀，将会发乌变绿。复色漆中几种颜料的密度不同，在贮存中重质颜料逐步下沉，轻质颜料逐步上浮，运用时如不充沛拌和均匀，施工后会和原色不符。酸值较高的清漆容易与铁质包装桶发作化学反应莽撞清漆透明度下降，色彩变深。在环氧地坪漆施工调色时禁止不通过实验，就随意将两种不同类型的涂料调配混合调色运用。部分颜料会发作化学改变，失掉颜料固有的上色力，引起褪色或变色。如含有铁蓝的蓝色或绿色漆，在贮存进程中会褪色，但施工后暴露在空气中的颜料会逐步康复。
Resins and pigments in paint formulation are selected according to need. The light and heat resistance of single pigments are not good. Some resins have poor weather resistance and are liable to yellowing when exposed to light. Metal powder pigments in storage will suffer from corrosion of residual free acid in the epoxy floor and will turn black to green. The density of several kinds of pigments in multicolor paints is different. Heavy pigments gradually sink in storage and light pigments gradually float. If they are not fully mixed and evenly used, they will not match the original color after construction. The varnish with higher acid value is easy to react with iron packaging barrel. The transparency of varnish decreases and the color becomes darker. It is forbidden to mix two different types of coatings at will without experimenting in the construction of epoxy floor paint. Some pigments will undergo chemical changes and lose the inherent coloring force of the pigment, resulting in 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.
In order to avoid premature fading of epoxy flooring in parking lots, the paint should be well mixed and even before construction, especially for the polychrome paint. Because there are many kinds of pigments with different densities, heavy pigments gradually sink in storage and light pigments gradually float. If they are not fully mixed and evenly used, they will not match the original color after construction.
When the pigments used in the construction of Weifang epoxy floor are still in storage, they must be separated from varnishes so as to avoid being corroded by the residual free acid in the paint and lead to color change. Especially those varnishes with high acid value are easy to react with iron packaging barrel to form varnish transparency decline and color deepening, so never use iron packaging container for storage.
During the construction of epoxy flooring, resins and pigments in the formulation of the paint must be selected according to the need. Because the light and heat resistance of the single pigments in the painting guess is not good, some resins have poor weather resistance, and turn back to discoloration when they meet the light, which is also one of the main reasons for the fading of the epoxy flooring in use. When formulating epoxy floor coatings, attention should be paid to the absence of pigments that can react with resins or additives.
It is forbidden to mix two different types of coatings and mix them at will without experimenting in the construction of color matching. All these improper practices will make the floor discolored. That is to say, as long as some of the pigments in the epoxy flooring paint undergo chemical changes, the inherent dyeing power of the pigments will be lost, resulting in fading or discoloration, thereby reducing the overall quality of the epoxy flooring.
