    环氧地坪漆膜开裂的程度分析怎么补办

    环氧地坪漆膜开裂环氧地坪漆涂膜开裂是指由于环氧地坪漆材料对底材失去应有的附着力,在外力的作用下使涂膜成小片或整张揭皮脱离物面的现象。其脱落程度可分为:直径约5mm以下的小片脱落,表现为大片脱落皮壳剥离。有两种情况的环氧地坪漆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。涂膜太厚的话,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。

    The cracking of epoxy floor paint film refers to the phenomenon that the epoxy floor paint material loses its due adhesion to the substrate and makes the film into small pieces or the whole strip peeled off the surface under the action of external force. The degree of shedding can be divided into: small shedding with a diameter of less than 5 mm, which is characterized by large shedding shell peeling. In two cases, the damage of epoxy floor paint is due to improper film thickness. One is that the coating is too thick, the other is that the coating 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 substrate. The lower layer of the film is soft, which easily causes foaming of the coating and poor adhesion to the substrate. 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。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。

    The improper solidification of the substrate by too thick coating will lead to scratch corrosion. For catalytic or internal curing epoxy floor paint, internal shrinkage will occur, causing cracking or even peeling of epoxy floor paint.

    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,这是常见的环氧环氧地坪漆损坏,施工者只要仔细施工就能避免的。

    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, which can be avoided as long as the builder works carefully.
