环氧地坪漆在涂装后因受各种因素的影响,不久就会产生部分断裂的现象,根据裂纹的形态(大小、深度、宽度)可分为发状裂纹、细裂纹、粗裂纹、龟裂、鳄鱼皮裂纹和玻璃裂纹等
Due to the influence of various factors on the surface of epoxy floor paint, some cracks will appear soon. According to the shape of cracks (size, depth and width), they can be divided into hair cracks, fine cracks, coarse cracks, cracks, crocodile skin cracks and glass cracks.
1、细裂 涂膜涂装后产生肉眼不易辨认,但用十倍显微镜可明显观察到的细纹。它是由涂装内部的收缩力超过涂膜本身内聚力而引起涂膜表面的破裂。它无损于涂膜的美观,是涂膜老化的必然结果。但如果在涂装后不久就出现此种情况,那就是一种病态。
1. Fine lines are not easily recognized by the naked eye, but can be clearly observed by a ten-fold microscope. It is caused by the internal force of the coating which exceeds the cohesion of the film itself and causes the rupture of the coating surface. It does not damage the appearance of the film, and is the inevitable result of the aging of the film. But if this happens soon after painting, it is a pathological condition.
2、粗裂 涂膜在涂装后不久产生明显粗裂纹,有时可见底的现象。
2. The rough crack coating has obvious cracks after coating, and sometimes it can see the bottom phenomenon.
3、龟裂 涂膜在涂装后出现形状类似龟背上纹路裂纹的现象。鳄鱼皮裂纹和玻璃裂纹也有此类似现象。
3. The appearance of cracked coating after coating is similar to that on the back of a turtle. Crocodile skin cracks and glass cracks also have similar phenomena.
涂膜开裂现象产生的原因、预防措施和解决方法如下:
The causes, preventive measures and solutions of the cracking phenomenon are as follows:
产生原因 防治方法
Causes and control methods
涂膜干燥后,硬度过高,而柔韧性又较差,如用含有共双键的脂肪酸或它的酯所配制的涂料 面漆硬度不宜过高,应注意涂料配方中涂膜的柔韧性
After drying, the hardness of the coatings is too high and the flexibility is poor. If the hardness of the coatings is not too high, the flexibility of the coatings should be paid attention to.
头道漆没干透就涂二道漆,两层涂膜内外伸缩力不一致 应在头道漆充分干透后再涂二道漆
Two coatings are applied before the first coat is dried thoroughly. The two coatings should be applied after the first coat is dried thoroughly.
涂层配套不适当,例如底漆层比面漆层涂膜软 通过试验解决涂层的配套性,一般使底漆涂层和面漆涂层的硬度、伸缩性接近
Inappropriate matching of coatings, such as primer coatings than top coatings soft coating through experiments to solve the compatibility of the coating, the primer coatings and top coatings generally make the hardness and flexibility close
面漆中挥发组分太多,影响成膜的结合力而引起涂膜干裂 面漆的挥发组分不宜过多
There are too many volatile components in the top coat, which will affect the adhesion of the film, so the volatile components of the dry cracked top coat should not be too much.
涂层过厚,表层干而内层没有干透 施工中每道涂膜不宜过厚
The coating is too thick, the surface layer is dry, and the inner layer is not dry.
催干剂用量过多或各种催干剂搭配不当 应注意催干剂的用量和搭配
Attention should be paid to the dosage and matching of drier for too much dosage of drier or improper matching of various driers.
涂膜在有污气(如二氧化硫、氨气等)的环境下应用 应避免在有污气的环境中施工和长时间使用
The application of coatings in the presence of dirty gases (such as sulfur dioxide, ammonia, etc.) should be avoided in the presence of dirty gases in the environment construction and long-term use.
色漆在使用前未搅匀,上层树脂多颜料少,而下层颜料多树脂少,涂装后容易开裂 色漆应充分搅拌均匀后再施工
The paint is not stirred well before use, the upper layer has more resin and less pigment, and the lower layer has more resin and less pigment.
涂层耐候性或耐温变性不佳 注意涂料的使用环境温度
Coating is weatherproof or temperature resistant. Attention should be paid to the ambient temperature of coating.
