    环氧地坪漆随着使用的时间增长,颜色也会逐渐的黯淡、少许的褪色等问题的出现,一般情况下环氧地坪漆的使用年限是5到15年,想要增加其使用的期限,需要做好环氧地坪漆日常养护。我们都知道环氧地坪漆材料是一种高强度、耐磨损、美观的环氧地坪材料,具有无接缝、质地坚实、耐药品性佳、防腐、防尘、保养方便、维护费用低廉等优点,一直受到大家的喜爱。然而,环氧地坪漆最大的弊病就是在一定的条件下发生色变现象,所谓的变色是指色漆褪色,或者是从一各颜色变成另外一个颜色。这各情况的发生最常见的是在施工的的时候或者存储的时候就已经发生了,具体原因环氧地坪漆厂家分析如下:

    With the increase of time, the color of epoxy floor paint will gradually fade, and some other problems will arise. Generally, the service life of epoxy floor paint is 5 to 15 years. In order to increase its service life, it is necessary to do a good job in the daily maintenance of epoxy floor paint. We all know that epoxy floor paint is a kind of high strength, wear-resistant, beautiful floor material, with seamless, solid texture, good resistance, anti-corrosion, dust-proof, easy maintenance, low maintenance costs and other advantages, has been loved by everyone. However, the biggest disadvantage of epoxy floor paints is that color change occurs under certain conditions. The so-called color change refers to the fading of paint, or from one color to another. The most common occurrence of these situations occurs at the time of construction or storage. The specific reasons are as follows: 

    环氧地坪漆材料变色的原因

    Reasons for discoloration of epoxy floor paint materials:

    1、颜料的密度差异过大:颜色是二种或二各以上的原色混合而成的,当色彩颜料的密度差异过大时,密度小的往上升,密度大的会往下沉,使颜料出现分层的现象,从而使得整体颜色出现不均匀的分布状态 。

    1. The density difference of the pigments is too large: the color is a mixture of two or more primary colors. When the density difference of the pigments is too large, the density of the pigments will rise, and the density of the pigments will sink, which will cause the phenomenon of layering of the pigments, thus resulting in the uneven distribution of the overall color.

    2、阳光暴晒:材料的耐候性不好,受到阳光的暴晒就会变黄;

    2. Sunshine exposure: materials with poor weather resistance will turn yellow when exposed to sunlight;

    3、被腐蚀的原因:金属粉末颜料被残留的游离酸腐蚀,导致颜料变成乌绿色;

    3. Causes of corrosion: metal powder pigments are corroded by residual free acid, resulting in dark green pigments;

    4、与桶发生反应:环氧地坪漆清漆的酸值较高与储存的铁桶发生化学反应,使得颜色变深;

    4. Reaction with barrel: The higher acid value of epoxy floor varnish reacts with the stored barrel to make the color darker;


    环氧地坪漆材料变色解决方法

    Solutions to the discoloration of epoxy floor paint materials:

    1、环氧地坪漆在使用时要进行长时间的搅拌。

    1. Epoxy floor paint should be stirred for a long time in use.

    2、按需要选择树脂和颜料,例如室外地坪漆则需选择耐光耐热性较好的水性聚氨酯地坪。

    2. Resins and pigments should be selected according to the needs, such as outdoor floor paints. Waterborne polyurethane floor with better light and heat resistance should be selected.

    3、金属的颜料与清漆要求分开储存,以免发生腐蚀现象;

    3. Metal pigments and varnishes should be stored separately to avoid corrosion.

    4、酸性较高的涂料最好不要使用铁质的桶来装。

    4. Coatings with high acidity should not be packed in iron barrels.
