    哪些因素导致了环氧地坪会出现变色的现象

    在实际操作过程中,许多用户表示反应无锡环氧地坪漆出现颜色现象,被认定为用户在施工环氧地坪漆时,环氧地坪施工前应充分搅拌好。颜料中几种颜料的质量密度后,重颜料逐渐在卖场中下沉,轻质颜料逐渐增多,如果使用时不充分搅拌,施工后会出现不一致和原色。哪些因素导致了环氧地坪会出现变色的现象?

    In the actual operation process, many users indicated that there was a color phenomenon in the reaction of Wuxi epoxy floor paint. It was recognized that the users should mix the epoxy floor paint well before construction. After the quality density of several kinds of pigments in the pigments, heavy pigments gradually sink in the stores, and light pigments gradually increase. If not fully stirred in use, inconsistencies and original colors will appear after construction. What factors lead to discoloration of epoxy floors? 

    金属漆应与清漆分开。金属粉末颜料在贮存过程中,漆中残留游离酸的腐蚀,会变成绿色。高酸值涂料不宜用铁桶包装。高酸值的清漆容易造成铁包装桶的化学反应,清漆的透明度降低,颜色变深。

    Metal paint should be separated from varnish. During the storage of metal powder pigments, the corrosion of residual free acids in paints will turn green. High acid value coatings should not be packed in iron drums. High acid value varnish is easy to cause the chemical reaction of iron packaging barrel. The transparency of varnish decreases and the color becomes darker.

    按要求选择油漆配方中的树脂和颜料。涂料中个别颜料的耐光性和耐热性不好。有些品种耐候性差。

    Select the resin and pigments in the paint formulation according to the requirements. The light and heat resistance of individual pigments in coatings are not good. Some varieties have poor weather resistance.

    在涂料配方设计中应注意,不可使用与树脂或助剂发生化学反应的颜料。施工调整时禁止使用两种不同类型的颜料混合和着色。材料中的一些色素会发生化学变化,失去色素中固有的色素,导致变色或变色。如果蓝色或绿色油漆含有铁蓝色,它会在储存期间褪色,但油漆将逐步恢复后建设。

    In the formulation design of coatings, it should be noted that pigments which react with resins or additives should not be used. It is forbidden to mix and colour two different types of pigments during construction adjustment. Some pigments in materials will undergo chemical changes and lose the inherent pigments in pigments, leading to discoloration or discoloration. If blue or green paint contains iron blue, it will fade during storage, but the paint will gradually recover after construction.
