    环氧地坪漆漆膜开裂原因及解决方法

    环氧地坪漆的一个重要特征就是整体无缝,但是在实际应用中经常会遇到施工后的出现开裂的问题(推荐:环氧地坪漆开裂问题怎么预防),影响环氧地坪工程的美观性。环氧地坪漆漆膜在使用一定年限后就会出现开裂、起壳等问题,但是在正常使用情况下环氧地坪漆漆膜开裂是在达到使用寿命(推荐:环氧地坪漆一般能用多长时间)之后,或者不正当使用导致。下面环氧地坪漆厂家就给大家分享环氧环氧地坪漆漆膜开裂的原因及处理方法。

    An important feature of epoxy floor paint is that it is seamless as a whole, but in practical application, cracking problems often occur after construction (recommendation: how to prevent cracking problems of epoxy floor paint), which affects the aesthetics of epoxy floor engineering. Epoxy floor paint film will crack and shell after a certain period of time, but in normal use, the cracking of epoxy floor paint film is after reaching its service life (recommendation: how long can epoxy floor paint generally be used), or is caused by improper use. The following epoxy floor paint manufacturers will share with you the causes and treatment of epoxy floor paint film cracking. 一、环氧环氧地坪漆漆膜开裂的原因及防治办法:

    1. Causes of cracking of epoxy floor paint film and preventive measures:

    1、环氧地坪受阳光暴洒或长期风吹,地坪干燥收缩而致使漆膜开裂(防治:环氧地坪耐候性差,应避免阳光直射);

    1. Epoxy floors are exposed to sunshine or long-term wind, drying and contraction of the floors result in cracking of paint film (prevention and treatment: poor weather resistance of epoxy floors, should avoid direct sunlight);

    2、漆膜过厚且没有充分干燥:施工过程中过于追求漆面光泽,盲目增加漆面厚度反复喷涂,且每次间隔时间太短,没有充分干燥而造成(防治:严格控制漆膜厚度,不能喷涂过厚、按照施工要求,每喷一层要充分干透后再喷第二层);

    2. Lacquer film is too thick and not sufficiently dry: in the process of construction, too much pursuit of paint gloss, blindly increasing the thickness of the paint surface is sprayed repeatedly, and each time interval is too short, resulting in insufficient drying (prevention and cure: strictly control the thickness of the paint film, can not be sprayed too thick, according to the construction requirements, each layer should be fully dried before spraying the second layer);

    3、基层含水率过高导致漆膜开裂(防治:施工地坪漆要求基面含水率不高于8%);

    3. Excessive moisture content in the base causes the cracking of the paint film (prevention and cure: the moisture content of the base surface is not higher than 8% for the construction floor paint);

    4、漆膜老化:使用时间过长、漆膜老化而自然开裂(防治:如果因漆膜老化而造成开裂,且漆膜出现松软现象应予以彻底铲除);

    4. Lacquer film aging: natural cracking due to long use time and aging of the film (prevention and cure: if cracking is caused by aging of the film, and the phenomenon of soft film should be eradicated thoroughly);

    5、地板受潮膨胀而致漆膜开裂或地板膨胀后相互挤压而致使漆膜开裂(防治:环氧地坪应禁止长时间被水浸泡);

    5. Lacquer film cracking caused by floor damp expansion or mutual extrusion caused by floor expansion (prevention and cure: epoxy floor should be prohibited from being immersed in water for a long time);

    6、兼容性差:底漆未干就滚涂面漆或面漆与底漆兼容性太差(掌控各种油漆使用性质,正确合理选用优质品牌,注意面漆与底漆的兼容性)。

    6. Poor compatibility: Rolling finish or top coat is not compatible with the primer before the primer is dry (controlling the nature of various paints, selecting high-quality brands correctly and reasonably, paying attention to the compatibility between the top coat and the primer).

    二、环氧地坪漆漆膜开裂处理方法

    II. Cracking Treatment of Epoxy Floor Paint Film

    1、对漆膜严重开裂,而用铲刀又铲不动的漆膜,可以采用“保守疗法”。等漆干燥后用砂纸打毛至无光状态,再在开了的漆膜上刮一层薄薄的腻子,重新做底(注意:前提是开裂漆膜的漆水铲不动的条件下可采用此法)。

    1. Conservative treatment can be applied to paint film which is severely cracked and can not be shoveled with a spade. After the paint is dried, sandpaper is used to wool it to a matte state, then a thin layer of putty is scraped on the open paint film to make a new bottom (note: this method can be used if the water shovel of the cracked paint film is not moved).

    2、对铲刀一铲就落的松散漆膜,只能彻底去漆砂磨至金属表面,再重新涂装。

    2. The loose paint film that falls off with a shovel of the spade knife can only be thoroughly removed and sanded to the metal surface, and then re-painted.

    3、为不影响地坪整体美观性及确保使用过程中能顺利使用,建议对龟裂的漆膜采取铲除再施工的方法处理,不可偷工减料而导致再返工等麻烦。

    3. In order not to affect the overall aesthetics of the floor and ensure smooth use in the use process, it is suggested that the cracked paint film should be removed and re-constructed, so that no Jerry work and material reduction can lead to re-work and other troubles.

    环氧地坪漆厂家提醒大家:在施工地坪漆的时候一定要严格按照环氧地坪漆施工工艺要求进行施工,这样才能避免漆膜开裂问题的出现。

    Guanglei floor paint manufacturer reminds you: when constructing floor paint, we must strictly follow the construction process requirements of epoxy floor paint, so as to avoid the appearance of film cracking problem.
