    环氧地坪处理伸缩缝的方法具体是什么

    相信不用多说,大家都知道在使用环氧地坪施完工后的效果是整体无缝隙的,所以在进行环氧地坪施工的时候,要先对混凝土地面的一些伸缩缝进行一些处理。1.环氧树脂砂浆填充法,在使用环氧地坪漆涂装的时候,使用环氧树脂类的刚性物质对伸缩缝进行填充,然后再按照环氧地坪施工工艺进行涂抹。在业主允许地面存在均一平直的伸缩缝的情况下,可以在环氧地坪漆装饰后切割机在原来的伸缩缝的位置切割二到五毫米宽的缝。给混凝土留下伸缩的空间,以用来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的现象发生。

    I believe that needless to say, everyone knows that the effect of using epoxy floor is seamless, so in the construction of epoxy floor, we should first deal with some expansion joints of concrete floor. 1. Epoxy resin mortar filling method, when using epoxy floor paint, filling expansion joints with rigid materials of epoxy resin, and then applying according to floor construction technology. Under the condition that the owner permits the floor to have uniform and straight expansion joints, the cutting machine can cut 2 to 5 mm wide seams in the original expansion joint position after the floor paint decoration. Leave space for concrete expansion to avoid uneven cracks on the ground in the future and reduce the occurrence of crusting along cracks in the floor coating. 2.聚氨酯弹性胶填充法,在环氧地坪涂料涂装时,先尽量将伸缩缝留着,即使覆盖,也应记录下所在的位置,然后在地坪涂装后,将伸缩缝切割修饰整齐,确保宽度在五毫米以上,建议修饰成上宽下窄的梯形状,然后清除缝内的的所有灰尘和杂物,贴缝两边贴上胶带,采用聚氨酯弹性交填充缝隙直且平直,在弹性胶半干状态撕去胶带即可。

    2. Polyurethane elastomer filling method, in the epoxy floor coating, first try to retain the expansion joint, even covering, should also record the location, and then after the floor coating, the expansion joint will be cut and modified neatly to ensure that the width is more than five millimeters. It is suggested that the expansion joint be modified into a narrow ladder shape, and then the inside of the joint will be cleared. All dust and debris, both sides of the seam are covered with adhesive tape, polyurethane elastic cross-filling gap is straight and straight, and the adhesive tape can be torn off in the semi-dry state of elastic adhesive.


    3.粘贴玻璃纤维布的方法,局部的地面有伸缩缝,也常采用铺贴玻璃纤维布来增强抗裂性的方法,施工方式是:先使用环氧砂浆材料将伸缩缝填充平整,再涂上底涂材料,再粘贴宽度十毫米左右的玻璃纤维布1-2道,接下来滚涂中涂材料,面漆等。这种方法不仅能确保地面整体颜色一致,还能抵御混凝土收缩引起的开裂现象,但是如果地坪涂层的设计厚度过薄,不易操作,就会很容易出现贴布处地面高于其它地方的现象。所以至少要在两毫米以上的环氧地坪才能使用这个方法。

    3. The method of gluing fiberglass cloth is that there are expansion joints on the local ground, and the method of gluing fiberglass cloth is often used to enhance the crack resistance. The construction method is: first fill the expansion joints with epoxy mortar material, then coat the bottom coating material, then glue 1-2 channels of fiberglass cloth with a width of about 10 mm, and then roll coating. Coating material, topcoat, etc. This method can not only ensure that the overall color of the ground is the same, but also resist the cracking caused by concrete shrinkage. But if the design thickness of the floor coating is too thin, it is not easy to operate, it will easily appear that the ground is higher than other places. So this method can only be used on epoxy floors of at least two millimeters or more.

    4.弹性胶填充的方法,在环氧地坪漆涂装时,可以采用弹性物质将伸缩缝进行填充补平,然后涂装中涂层和面漆。先检验各个伸缩缝,对于宽度在五毫米以上的,将里面的杂物和灰尘清理干净,再配好弹性胶进行填充刮平。然而对于小于五毫米的伸缩缝,因为其缝隙窄不容易填充,所以要先使用切割接切到一定的宽度和深度的梯型,但要保证切割的蒸汽,然后管注弹性胶即可。具体方法是采用玻璃枪填充,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楚干净,否则易出现弹性胶与混凝土附着不牢而脱离的现象。

    4. Elastic rubber filling method, in the epoxy floor paint coating, can use elastic material to fill expansion joints, and then coating and topcoat. First check the expansion joints, for the width of more than five millimeters, the debris and dust will be cleaned up, and then with elastic rubber for filling and scraping. However, for the expansion joints less than 5 mm, because the gap is narrow and not easy to fill, it is necessary to use the trapezoidal cut to a certain width and depth, but to ensure the steam cut, and then inject elastic glue into the pipe. The concrete method is to fill the gap with glass gun. After filling the gap, scrape with spade and remove excess rubber. Elastic rubber filling needs a certain depth. The dust and other debris in the gap before filling should be clear and clean. Otherwise, it is easy to separate the elastic rubber from the concrete due to its weak adhesion.
