為什么環(huán)氧地坪遇水會(huì)變白?預(yù)防措施及解決辦
環(huán)氧地坪漆遇水變白是指涂層在干燥過程中,環(huán)氧地坪漆表面產(chǎn)生霧狀導(dǎo)致光澤度下降,直接影響了環(huán)氧地坪的裝飾效果。因此,為了確保工程質(zhì)量,一定要杜絕環(huán)氧地坪漆雨水變白現(xiàn)象的產(chǎn)生。下面,環(huán)氧地坪漆廠家就給大家分享環(huán)氧地坪漆遇水變白的原因、預(yù)防措施及解決辦法。環(huán)氧地坪漆遇水變白的主要原因:
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、施工周圍環(huán)境濕度過大,導(dǎo)致空氣中的水分直接進(jìn)人涂層。
1. The ambient humidity around the construction is too high, which causes the moisture in the air to enter directly into the coating.
2、當(dāng)空氣溫度低、濕度大的時(shí)候,涂層中的溶劑揮發(fā)速度將會(huì)引起涂層表面溫度急劇下降,很容易使空氣中的濕氣在涂層表面凝結(jié)成水分浸入涂層中,結(jié)果導(dǎo)致霧狀發(fā)白,并將此種發(fā)白稱為“潮濕性發(fā)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、由于涂料中的真溶劑揮發(fā)比其稀釋劑快得過多,結(jié)果引起涂層中部分樹脂析出成白色沉淀,使涂層發(fā)白,并將這種發(fā)白稱為“樹脂性發(fā)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".
為避免環(huán)氧地坪漆遇水發(fā)白應(yīng)做好以下三點(diǎn):
In order to avoid the whitening of epoxy floor paint in water, the following three points should be done well:
1、提高涂飾施工環(huán)境的溫度減少空氣的濕度。
1. Raise the temperature of painting construction environment and reduce the humidity of air.
2、在涂料中要適當(dāng)增加真溶劑與稀釋劑的沸點(diǎn)。
2. The boiling points of real solvents and diluents should be properly increased in coatings.
3、按照環(huán)氧環(huán)氧地坪漆施工工藝施工時(shí),確保施工環(huán)境溫度在10-30℃之間。過低或者過高都會(huì)影響地坪漆的反應(yīng)過程,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.
當(dāng)環(huán)氧地坪漆出現(xiàn)發(fā)白現(xiàn)象時(shí)可以采用以下措施進(jìn)行改善:
When the whitening of epoxy floor paint occurs, the following measures can be taken to improve it:
1、適當(dāng)增加涂層干燥溫度,在條件允許的情況下采用紅外線輻射器干燥涂層,使潮氣從涂層中揮發(fā)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、在涂層發(fā)白處輕輕刷涂一層薄薄的該涂料的真溶劑,使涂層中析出的樹脂重新溶解成連續(xù)的涂層,或使涂層中的水氣自由的揮發(fā)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.
