    环氧地坪施前工对地面要求及处理方法

    现如今比较流行的环氧地坪漆属于环氧地坪漆中的一大类,依据组成成分的不同可以划分为好多种,而且不同的环氧地坪产品拥有的性能和功能、应用领域也不相同,比如常见的地坪功能有耐磨、抗压、防静电等,不管是哪种功能的地坪漆重要的还是施工前的地面处理,我们经常见到的漆膜问题大多数是由底材处理不当引起的,今天我们着重了解一下地面的处理和要求,以及未做好地面处理带来的影响。

    Nowadays, the more popular epoxy floor paints belong to a large category of floor paints, which can be divided into many kinds according to the different composition, and different floor products have different performances and functions and application fields, such as wear-resistant, pressure-resistant, antistatic and other common floor functions, no matter what kind of function they are. The most important thing is the surface treatment before construction. Most of the paint film problems we often see are caused by improper substrate treatment. Today we focus on the surface treatment and requirements, as well as the impact of improper surface treatment. 环氧地坪施工前地面要求及处理

    Ground requirement and treatment before epoxy floor construction

    环氧地坪漆施工前的地面处理和其它工业漆一样都要求底材清洁、干燥,没有油污灰尘,由于地坪漆的施工基面大多为水泥、混凝土,此时我们还要注意混凝土地面上不能有裂缝、空洞。旧的混凝土地面可能会疏松、浮尘,也需要对地面进行强化,以提高附着力。

    The ground treatment before the construction of epoxy floor paint, like other industrial paints, requires a clean and dry base material without oil and dust. Because the construction base surface of epoxy floor paint is mostly cement and concrete, we should also pay attention to the fact that there are no cracks and voids on the concrete floor at this time. Old concrete floors may be loose and dusty, and need to be strengthened to improve adhesion.

    ■ 混凝土进行认真打磨,不能漏掉半点不打磨的地方,特别是很多强度不好的区域,一定要打磨到有强度的地方。

    Careful polishing of concrete should not omit any unpolished areas, especially in areas with poor strength, so it is necessary to polish to areas with strong strength.

    否则,疏松的区域会随着涂层脱落,而且时间会很快,可能工程还没有结算就会脱掉。

    Otherwise, the loose area will fall off with the coating, and the time will be very fast. Maybe it will fall off before the project is settled.

    同时,建议打磨进行两道,两次呈十字交叉型,以防止有漏点,可以打磨得更加彻底。

    At the same time, it is suggested that two routes of grinding should be carried out, and the two rounds should be cross-shaped, so as to prevent leakage and to grind more thoroughly.

    ■ 打磨结束后,清扫完后,建议用吸尘器吸尘处理,以便涂料更好地渗透,水的张力大,容易影响渗透性;

    After polishing and cleaning, it is suggested to use vacuum cleaner for better penetration of paint, high water tension and easy to affect penetration.

    ■ 对于没有伸缩缝的地面,要进行深切缝,以防止将来由于混凝土的内应力,形成不规则裂缝;有伸缩缝的地方,用钢筋钩进行清缝,然后用吸尘器进行吸尘。

    For the ground without expansion joints, deep cutting should be carried out to prevent irregular cracks due to the internal stress of concrete in the future. Where there are expansion joints, the steel bar hook is used to clean the joints, and then vacuum cleaner is used.

    ■ 有不规则裂缝的地方,要进行切缝处理,用环氧砂浆进行修补,并注意修补的高低差;

    Where there are irregular cracks, it is necessary to cut the cracks, repair them with epoxy mortar, and pay attention to the difference of the repair height.

    ■ 柱边和墙角边用角磨机进行角磨,处理的平整、平滑;

    The corner grinding is carried out with the corner grinder on the side of the column and corner.

    ■ 有水的地方用吸水器把水处理掉,铲除表面的泥浆,然后用带水的洗地机洗地吸水,处理干净,晾一天,随后上底漆;

    Where there is water, water is treated with a water absorber, the mud on the surface is removed, and then the ground is washed with a washing machine with water to absorb water, which is cleaned and aired for one day, followed by primer.

    ■ 有油污的地方,先把表面的油垢铲除干净,然后用清洗剂进行清洗,然后再用火烤,如果油污特别严重,需要敲掉混凝土重新浇筑。

    Where there is greasy dirt, first remove the greasy dirt from the surface, then clean it with detergent, and then bake it on fire. If the greasy dirt is very serious, it is necessary to knock out the concrete and re-pour it.

    环氧地坪施工前未做好地面处理会带来的影响

    The influence of surface treatment on the construction of epoxy floor before construction

    抗压性差,起皮脱层

    Poor skin pressure, peel off layer.

    如果直接在强度没有达到C25以上的混凝土水泥地面做环氧地坪漆,在被重型叉车等碾压的时候,会因为基层强度不够,造成环氧地坪与基面一起被压陷拉裂,出现起皮脱层等问题。

    If epoxy floor paint is made directly on concrete cement floor whose strength does not reach C25 or above, when it is rolled by heavy forklift trucks, it will cause the epoxy floor to be collapsed and cracked together with the base, resulting in peeling and delamination.

    表面不平整

    Surface roughness

    因为环氧地坪只是附着于基础地面上的一层薄薄的涂膜,如果在涂刷环氧地坪漆之前没有将地面打磨平整,将会造成环氧地坪施工后表面凹凸不平,这极大了影响环氧地坪整体的美观度。

    Because the epoxy floor is only a thin film attached to the foundation floor, if the ground is not polished flat before the epoxy floor paint is applied, the surface of the epoxy floor will be uneven after construction, which greatly affects the overall aesthetics of the epoxy floor.

    环氧地坪失光

    Epoxy floor loss

    正常来说,环氧地坪漆施工后表面应该是光亮平整的,如果施工前没有对地面进行充分打磨平整,就会导致地坪漆施工后是坑坑洼洼的,失去应有的光泽度。

    Normally, the surface of epoxy floor paint should be bright and flat after construction. If the ground is not fully polished and smooth before construction, it will lead to pits and depressions after construction, and lose its due gloss.

    附着力差

    Poor adhesion

    基面被污染是非常常见的一种现象,环氧地坪漆施工之前如果没有将油污清除干净,势必会导致环氧树脂底漆无法很好的渗透到基础地面,严重影响了地坪漆涂层的附着力,后期就可能出现起皮起壳等问题。

    Foundation surface contamination is a very common phenomenon. If the oil contamination is not cleaned up before the construction of epoxy floor paint, it will inevitably lead to the epoxy resin primer can not penetrate into the foundation ground very well, seriously affecting the adhesion of the floor paint coating, and later there may be some problems such as peeling and shelling.

    所以要做好环氧地坪,一定要做好基层地面的处理,做好清洁处理工作,确保基层地面符合地坪漆的施工要求,只要做好涂装前的准备工作才能确保获得优异的漆膜涂刷效果。

    Therefore, in order to do a good job of epoxy flooring, we must do a good job of grass-roots floor treatment, do a good job of cleaning, to ensure that the grass-roots floor meets the construction requirements of floor paint, as long as we do a good job of preparation before painting to ensure excellent paint film painting effect.
