    哪些因素导致环氧地坪开裂的?解决方法

    环氧地坪适用各种区域,比如电子厂房、医院、化学工厂、服装厂、仓库等地方。提醒正在施工环氧地坪的朋友注意了,一定要注意以下几点,让大家预防环氧地坪开裂。缺陷状况:1.环氧地坪细裂: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。

    Epoxy floor is suitable for various areas, such as electronic factory, hospital, chemical factory, garment factory, warehouse and so on. Reminds the friends who are constructing the epoxy floor to pay attention to, must pay attention to the following points, lets everybody prevent the epoxy floor cracking. Defects: 1. Fine cracks in epoxy floors: Fine lines can be observed with a ten-fold microscope, though they are not easily recognized by the naked eye after coating. 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.环氧地坪粗裂:涂膜在涂装后不久产生明显粗裂纹,有时可见底的现象。

    2. epoxy floor crack: the coating will produce obvious cracks shortly after coating, and sometimes the bottom phenomenon can be seen.

    3.环氧环氧地坪龟裂: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. epoxy floor cracks: the coating appears after the painting is similar to the phenomenon of cracks on the back of the turtle. Crocodile skin cracks and glass cracks also have similar phenomena.

    环氧环氧地坪开裂原因:

    Causes of cracking on epoxy floor:

    1.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;

    1. Coatings with high hardness and poor flexibility after drying, such as coatings made from fatty acids or esters containing co-double bonds;

    2.头道漆没干透就涂二道漆,两层涂膜内外伸缩力不一致;

    2. the first coat of paint is not dry enough to be painted with two lacquers, and the two layers of coating have different internal and external expansion forces.

    3.涂层配套不适当,例如底漆层比面漆层涂膜软;

    3. the coating is not suitable, for example, the primer layer is more flexible than the topcoat coating.

    4.环氧地坪面漆中挥发组分太多,影响成膜的结合力而引起涂膜干裂;

    4. there are too many volatile components in epoxy floor coatings, which affect the bonding force of film forming and cause the film to dry crack.

    5.涂层过厚,表层干而内层没有干透;

    5. the coating is too thick, the surface layer is dry and the inner layer is not dried.

    6.催干剂用量过多或各种催干剂搭配不当;

    6. excessive dosage of drier or improper matching of various driers.

    7.涂膜在有污气(如二氧化硫、氨气等)的环境下应用;

    7. coating is applied in polluted environment such as sulfur dioxide and ammonia.

    8.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;

    8. The paint is not stirred before use, the upper resin has more pigments and less, while the lower paint has more pigments and less resins, so it is easy to crack after painting.

    9.涂层耐候性或耐温变性不佳

    9. the weatherability or temperature resistance of the coating is poor.
