    环氧地坪漆施工前伸缩缝处理方法

    进行环氧地坪漆施工时常常会遇到地面存在伸缩缝,这时候就需要先对伸缩缝进行处理,否则会导致施工后的环氧地坪漆出现开裂、起皮、起鼓等现象。因此,为了保证环氧地坪漆工程质量,做出优质的环氧地坪漆项目,需要做好伸缩缝等处理工作。下面就由环氧地坪漆厂家给大家详细介绍一下环氧地坪漆施工前伸缩缝处理方法。

    During the construction of epoxy floor paint, there are often expansion joints on the ground. At this time, the expansion joints need to be treated first. Otherwise, the epoxy floor paint will crack, peel and drum after construction. Therefore, in order to ensure the quality of floor paint project and make high-quality floor paint project, it is necessary to do a good job in the treatment of expansion joints and so on. Next, Guanglei floor paint manufacturers will give you a detailed description of the epoxy floor paint before the construction of expansion joint treatment methods. 1、用环氧树脂砂浆类(应是无溶剂产品)刚性物质将伸缩缝进行填充,然后按地坪整体涂装的工艺进行,涂装完毕后开裂发生前,地坪涂层上看不到伸缩缝。这种方式不能保证伸缩缝处或附近的地坪涂层不出现开裂和起壳现象。因这类钢性物质并无弹性,无法抵御混凝土收缩开裂时的应力,开裂就无法避免。

    1. Fill expansion joints with epoxy mortar (which should be solvent-free) rigid material, and then proceed according to the whole painting process of the floor. No expansion joints can be seen on the floor coating before cracking occurs after finishing painting. This method can not ensure that cracking and shelling do not occur in the floor coating at or near the expansion joint. Because this kind of steel material has no elasticity, it can not resist the stress of concrete shrinkage cracking, cracking can not be avoided.

    如果允许地面存在均一平直的伸缩缝,则可在地坪涂装完毕后用切割机在原伸缩缝位置切割2-5毫米宽的伸缩缝,给混凝土留下伸缩的空间,可避免日后地面出现不均一的裂缝和减少地坪涂层沿裂缝起壳现象。通常只有在地面装饰要求不高的场合,这种方式才能接受。

    If uniform and straight expansion joints are allowed on the ground, 2-5 mm wide expansion joints can be cut by cutting machine at the original expansion joints position after coating, leaving expansion space for concrete, which can avoid uneven cracks on the ground in the future and reduce the phenomenon of crust formation along the cracks of the floor coating. Usually this method is acceptable only when the ground decoration requirements are not high.

    2、采用弹性物质(如聚氨酯弹性胶)将伸缩缝进行填充补平,然后涂装中涂层和面漆。具体操作方式如下:首先检验各伸缩缝,对宽度在5mm以上的伸缩缝,将缝内杂物清理干净,然后配好弹性胶进行填充并刮平。对于宽度小于5mm的伸缩缝,由于缝太细不易填充,需先用切割机切割达到一定宽度和深度(深度在1mm以上比较好)的梯形状,需保证切割整齐,然后才能灌注弹性胶。

    2. Use elastic material (such as polyurethane elastomer) to fill and flatten the expansion joint, and then coat and finish. Specific operation methods are as follows: First, check the expansion joints, the expansion joints with a width of more than 5 mm, clean up the debris in the joints, and then fill them with elastic glue and scrape them flat. For expansion joints whose width is less than 5 mm, because the seams are too thin to be filled, it is necessary to use a cutting machine to cut the ladder shape with a certain width and depth (the depth is better than 1 mm), to ensure that the cutting is neat, and then the elastic glue can be perfused.

    弹性胶填充方法:根据弹性胶生产厂家的产品说明进行或采用玻璃枪(打胶枪)填充,需注意尽量避免缝外沾染上胶料,如沾上,应立即清除,缝隙填满后,用铲刀刮平并去除多余胶料。弹性胶填充需有一定的深度,填充前缝隙内的灰尘等杂物应清除干净,否则易出现弹性胶与混凝土附着不牢而脱离现象。

    Elastic glue filling method: According to the product instructions of elastic glue manufacturer or using glass gun, attention should be paid to avoid contamination with glue outside the seam as far as possible. If contamination occurs, it should be cleared immediately. After filling the gap, scrape with spatula and remove excess glue. Elastic glue filling needs a certain depth. The dust and other debris in the gap before filling should be cleaned up. Otherwise, it is easy for elastic glue to adhere to concrete and separate from it.
