    环氧地坪漆裂缝是否与漆膜厚度有关?

    环氧地坪漆涂膜厚度不够会致使其出现裂缝吗?对此,环氧地坪漆厂家表示,答案是肯定的。如果环氧地坪漆涂膜厚度不够,针孔,飞漆,干燥不当,固化不当等,都会导致环氧树脂地坪漆出现裂缝。有两种环氧树脂地坪漆的损坏是由于涂膜厚度不当造成的。一种是堆漆造成的涂膜太厚,另一种就是涂膜太薄。涂膜太厚,挥发性漆的涂膜干燥就不好,涂膜中残留的溶剂靠近基材,下层涂膜较软,易引起涂层起泡和与基材粘结不牢,而过厚涂层对基材的不牢枯结,会导致划痕腐蚀的迅速产生。

    Does the lack of film thickness of epoxy floor paint cause cracks? To this end, the epoxy floor paint manufacturer said that the answer is yes. If the film thickness of epoxy floor paint is not enough, pinholes, flying paint, improper drying, improper curing, etc., will lead to cracks in epoxy floor paint. Two kinds of epoxy floor paint are damaged due to improper film thickness. One is that the paint is too thick, the other is that the film is too thin. If the film is too thick, the drying of the volatile paint film is not good. The residual solvent in the film is close to the base material, and the lower layer is soft. It is easy to cause foaming of the coating and bonding with the base material is not strong. However, if the thick coating is not firm to the base material, scratch corrosion will occur quickly. 

    对于催化或内固化型环氧地坪漆来说,则会产生内部收缩,引起环氧地坪漆开裂,甚至剥落。涂层太薄,通常是快速施工造成表面漆料太少的结果。在这些区域发生的环氧地坪漆损坏主要是从点蚀开始的,随着点渐渐扩大,整个被涂表面在最薄的区域发生划痕腐蚀,这是常见的环氧地坪漆损坏,施工者只要仔细施工就能做好。

    For catalytic or internal curing epoxy floor paint, internal shrinkage will occur, causing cracking or even peeling of epoxy floor paint. The coating is too thin, usually resulting from too little paint on the surface due to rapid construction. The damage of epoxy floor paint in these areas mainly starts from pitting corrosion. As the dots gradually expand, scratch corrosion occurs in the thinnest area of the coated surface. This is a common damage of epoxy floor paint. As long as the builder works carefully, he can do a good job.
