    为什么环氧地坪遇水会变白?预防措施及解决办

    环氧地坪漆遇水变白是指涂层在干燥过程中,环氧地坪漆表面产生雾状导致光泽度下降,直接影响了环氧地坪的装饰效果。因此,为了确保工程质量,一定要杜绝环氧地坪漆雨水变白现象的产生。下面,环氧地坪漆厂家就给大家分享环氧地坪漆遇水变白的原因、预防措施及解决办法。环氧地坪漆遇水变白的主要原因:

    The whitening of epoxy floor paint in water refers to the foggy appearance on the surface of the coating during the drying process, which results in the decrease of gloss and directly affects the decorative effect of the epoxy floor paint. Therefore, in order to ensure the quality of the project, it is necessary to eliminate the phenomenon of rainwater whitening of epoxy floor paint. Next, epoxy floor paint manufacturers will share with you the reasons for the whitening of epoxy floor paint in water, preventive measures and solutions. The main reasons for the whitening of epoxy floor paint in the presence of water are as follows: 1、施工周围环境湿度过大,导致空气中的水分直接进人涂层。

    1. The ambient humidity around the construction is too high, which causes the moisture in the air to enter directly into the coating.

    2、当空气温度低、湿度大的时候,涂层中的溶剂挥发速度将会引起涂层表面温度急剧下降,很容易使空气中的湿气在涂层表面凝结成水分浸入涂层中,结果导致雾状发白,并将此种发白称为“潮湿性发白”。

    2. When the air temperature is low and the humidity is high, the solvent evaporation rate in the coating will cause the surface temperature of the coating to drop sharply. It is easy to make the moisture in the air condense on the coating surface into water and immerse in the coating. As a result, the foggy whitening will occur, and this kind of whitening will be called "wet whitening".

    3、由于涂料中的真溶剂挥发比其稀释剂快得过多,结果引起涂层中部分树脂析出成白色沉淀,使涂层发白,并将这种发白称为“树脂性发白”。

    3. Because the volatilization of real solvent in coatings is faster than that of diluents, some resins in coatings precipitate into white precipitation, which makes the coatings white. This kind of whitening is called "resin whitening".

    为避免环氧地坪漆遇水发白应做好以下三点:

    In order to avoid the whitening of epoxy floor paint in water, the following three points should be done well:

    1、提高涂饰施工环境的温度减少空气的湿度。

    1. Raise the temperature of painting construction environment and reduce the humidity of air.

    2、在涂料中要适当增加真溶剂与稀释剂的沸点。

    2. The boiling points of real solvents and diluents should be properly increased in coatings.

    3、按照环氧环氧地坪漆施工工艺施工时,确保施工环境温度在10-30℃之间。过低或者过高都会影响地坪漆的反应过程,造成固化不良。

    3. In accordance with the construction technology of epoxy floor paint, ensure that the construction environment temperature is between 10-30 degrees Celsius. Too low or too high will affect the reaction process of floor paint, resulting in poor curing.

    当环氧地坪漆出现发白现象时可以采用以下措施进行改善:

    When the whitening of epoxy floor paint occurs, the following measures can be taken to improve it:

    1、适当增加涂层干燥温度,在条件允许的情况下采用红外线辐射器干燥涂层,使潮气从涂层中挥发掉。

    1. Increase the drying temperature of the coating properly, and use infrared radiator to dry the coating when conditions permit, so that the moisture evaporates from the coating.

    2、在涂层发白处轻轻刷涂一层薄薄的该涂料的真溶剂,使涂层中析出的树脂重新溶解成连续的涂层,或使涂层中的水气自由的挥发出去。

    2. Gently brush a thin layer of true solvent on the whitening part of the coating to dissolve the resin precipitated from the coating into a continuous coating, or to make the water vapor in the coating volatilize freely.
