水性镇江环氧地坪漆以水作溶剂,尤其适合地下水位较高或者没做防水层的地下室、仓库及停车场等基面潮湿的场所,能有效解决潮湿地面普通苏州环氧地坪漆涂层容易起泡的问题。那么水性环氧地坪漆能防止涂膜起泡的原理是什么呢?下面光磊环氧地坪漆厂家就给大家详细介绍。对于普通环氧地坪漆来说,起泡的原因是多方面的,但都是同一个原理,就是环氧地坪漆下有水分,在气温较高时发生膨胀造成的。水分的来源主要是基层、环氧地坪漆配料脱水不净或施工时造成的,其中基层的含水量最大。普通的环氧地坪漆漆膜致密,基面潮气蒸发后无法透过漆膜逸出,从而形成上顶的压力,造成涂膜起泡。而由于水性环氧地坪漆以水作溶剂,固化后的漆膜上有细微的孔隙,基层中的水汽可以透过这些孔隙逸出,排解了基面水汽蒸发产生的压力,有效防止地坪漆涂层起泡。
Waterborne epoxy floor paint uses water as solvent. It is especially suitable for basement, warehouse and parking area with high groundwater level or without waterproof layer. It can effectively solve the foaming problem of common epoxy floor paint coating on wet ground. So what is the principle of waterborne epoxy floor paint to prevent blistering? The following Guanglei floor paint manufacturers will give you a detailed introduction. For ordinary epoxy floor paint, there are many reasons for foaming, but they are all the same principle, that is, there is water under the epoxy floor paint, which is caused by expansion when the temperature is higher. The main source of moisture is the dehydration of the ingredients of base and epoxy floor paint or the construction, of which the moisture content of base is the largest. The common floor paint film is compact and can not escape through the paint film after moisture evaporation on the base surface, thus forming the pressure on the top and causing the blistering of the paint film. Because water-borne epoxy floor paint uses water as solvent, there are fine pores in the cured film. Water vapor in the base can escape through these pores, which can relieve the pressure caused by vapor evaporation on the base and effectively prevent the foaming of the floor paint coating.
The difference between waterborne epoxy floor paint and common epoxy floor paint is as follows:
1、溶剂不同。以水代替溶剂进行稀释是水性环氧地坪漆和溶剂型环氧地坪漆的最大区别。
1. Different solvents. Dilution with water instead of solvent is the biggest difference between waterborne epoxy floor paint and solvent-based epoxy floor paint.
2、组分上的区别。溶剂型环氧地坪漆的色漆组分是树脂组分,固化剂是改性胺,而水性环氧地坪漆刚好相反。
2. Component differences. Solvent-based epoxy floor paint is composed of resin, curing agent is modified amine, while water-based epoxy floor paint is just the opposite.
3、性能上的区别。水性环氧地坪漆的收缩性比较强,应尽可能刮薄,不可漫涂,否则会出现开裂的现象。
3. Performance differences. The shrinkage of waterborne epoxy floor paint is relatively strong. It should be scraped as thin as possible and not spread, otherwise cracking will occur.
4、其它。水性环氧地坪漆对搅拌器的要求较高,需要用到齿盘型搅拌器,且需要有功率和较快的转速。
4. Others. Waterborne epoxy floor paint requires a high agitator. It needs a toothed disc agitator with high power and fast speed.
