    低温对环氧地坪涂料施工影响有哪些?

    低温对环氧地坪涂料施工影响有哪些?从事此方面工作的人员应该都了解,环氧地坪涂料最佳施工环境是温度在10-35℃,湿度小过75%,通常温度5℃上也可以施工,但低于5℃,环氧地坪涂料地面施工实际效果就不能保证了。在低温环境下,为何环氧地坪涂料就很难施工?环氧地坪分析原因主要有下面几点:

    What are the effects of low temperature on epoxy floor coating construction? Personnel engaged in this work should be aware that the best application environment of epoxy floor coating is the temperature of 10-35 C, humidity less than 75%. Usually the temperature of 5 C can also be used, but below 5 C, the actual effect of epoxy floor coating construction can not be guaranteed. In the low temperature environment, why is epoxy floor coating difficult to construct? The reasons for epoxy floor analysis are as follows: 1、降低涂膜质量

    1, reduce coating quality.

    因为固化反应减慢,或完成不可以固化,涂膜强度、耐磨性和硬度都会下降,且会更容易出现环氧地坪脱离等现象,这严重影响环氧环氧地坪使用寿命。

    Because the curing reaction is slowed down or the curing can not be completed, the film strength, wear resistance and hardness will be reduced, and more likely to occur floor disengagement and other phenomena, which seriously affects the life of the epoxy floor.

    2、减慢涂料反应

    2, slow down the paint reaction.

    双组分的地坪涂料施工,需要现场将两组分别按照5:1或1:1的比率来进行混合,搅拌均匀,让双组分充分的反应,这样才可以保证环氧地坪施工效果,但若温度低于5℃,双组分反应就会下降或者减缓,这严重影响地坪涂料固化性能。

    In the construction of two-component floor coatings, it is necessary to mix the two groups according to the ratio of 5:1 or 1:1, mixing evenly, so that the two components can react sufficiently, so as to ensure the construction effect of epoxy floor coatings. However, if the temperature is lower than 5 C, the two-component reaction will decrease or slow down, which seriously affects the solidification of floor coatings. Yes.

    环氧地坪表示,而固化性能的下降,会导致涂膜表面干的非常慢,也会增加涂膜被灰尘、昆虫(比如蚊子、苍蝇)或者杂物污染的可能。

    Epoxy floors show that a decline in curing performance can cause the film to dry very slowly and increase the possibility of contamination by dust, insects (such as mosquitoes, flies) or debris.

    3、黏度成倍增长

    3. Viscosity increases exponentially.

    没有溶剂的自流平涂料不需要刮涂,只需要依靠流平性来保障环氧地坪的平整度,但在低温环境下,地坪涂料的粘度会成倍的增加,流平性能也将不断降低,而没有靠流平性的涂料,在刮涂的时候会由于流动、流平性能变差、而出现镘刀痕的缺陷。

    Self-leveling coatings without solvents do not require scraping, but only rely on leveling to ensure the smoothness of the epoxy floor, but at low temperatures, the viscosity of the floor coatings will increase exponentially, leveling performance will continue to decline, and no leveling coatings, in the scraping process due to flow, leveling performance will deteriorate. And there are defects in the trowel marks.
