    环氧地坪的特点及施工前怎么解决防水层的问题?

    环氧地坪与防水层其实有相当大的关系,很多人认为环氧是“防水”的,所以说,不重视防水层,后果很严重,经常看到空鼓开裂的环氧地坪,这很大可能性与下面没有防水层或防水层已经失效有关,剩下的如何解决防水层问题,结构防水做法好像又与做环氧地坪的不是一家,做环氧地坪的只能是要求做的时候测含水率及要求基面强度,就是达到要求,做上去了,一旦下面有水上来,什么环氧地坪也基本挡不住。

    Epoxy flooring and waterproof layer actually have a considerable relationship, many people think that epoxy is "waterproof", so that pay no attention to waterproof layer, the consequences are very serious, often see hollow cracked epoxy flooring, which is very likely related to the following no waterproof layer or waterproof layer has failed, the remaining how to solve the problem of waterproof layer. It seems that the method of structural waterproofing is not the same as that of making epoxy flooring. The only way to make epoxy flooring is to measure moisture content and strength of the base when required. That is to say, it meets the requirements. Once there is water below, any flooring can hardly be blocked.

    环氧树脂对湿面有一定的润湿力,尤其在使用聚酰胺树脂作固化剂时,可制成水下施工涂料,能排挤物体表面的水而涂布,可用于水下结构的抢修和水下结构的防腐蚀施工。防水层对于环氧地坪漆的使用年限有着重要影响,尤其是地下及一楼的环氧地坪系统。如果防水层没有做好,则后期环氧地坪漆系统很容易出现气泡、脱层等现象。

    Epoxy resin has a certain wetting force on wet surface. Especially when polyamide resin is used as curing agent, it can be made into underwater construction coatings, which can squeeze out the water on the surface of objects, and can be used for emergency repair of underwater structures and anti-corrosion construction of underwater structures. Waterproof layer has an important influence on the service life of epoxy floor paint, especially the epoxy floor system of underground and first floor. If the waterproofing layer is not well done, it is easy to appear bubbles, delamination and other phenomena in the late floor paint system.

    首先在施工防水层前,需要先将基面处理好,保证其含水率控制在4%以下。如果地面太潮湿,则可以用用鼓风面鼓风或者用太阳灯照射基面,一般基层干燥时间要求28天以上。

    First, before the construction of waterproof layer, it is necessary to treat the base surface well to ensure that its moisture content is controlled below 4%. If the ground is too wet, it can be blown by blast surface or illuminated by solar lamp. Generally, the drying time of grass-roots requires more than 28 days.

    接下来就需要施工重要的防水层了。一般情况有两种:

    Next, important waterproofing layers need to be constructed. There are two general situations:

    1、铺设细砂、薄膜。铺设塑料薄膜在地面回填后进行。首先在回填土表层铺一层细砂,再铺设不透水的油毡和塑料薄膜,最后再浇筑混凝土层。对于两块塑料薄膜的搭接处至少要有10CM的重叠。

    1. Laying fine sand and thin film. Laying plastic film on the ground after backfilling. First, a layer of fine sand is laid on the surface of backfill soil, then impermeable felt and plastic film are laid, and finally concrete layer is poured. For the overlap of two plastic films, at least 10CM should be overlapped.

    2、涂布防水涂料,先在环氧地坪漆施工水泥地面上涂布一层防水涂料,形成防水隔离层,然后施工一层水泥砂浆保护层,最后在水泥砂浆保护层上面施工环氧地坪漆。防水涂料是指涂刷在建筑物表面上,经溶剂或水分的挥发或两种组分的化学反应形成一层薄膜,使建筑物表面与水隔绝,从而起到防水、密封的作用的粘稠液体。
