    环氧地坪施工时对混凝土基材的要求有哪些?

    现在很多场所所用混凝土铺面后,还会使用环氧地坪来保护地面,这样可以很好的延长地面的使用年限,那么环氧地坪施工时对混凝土基材的要求是什么呢?一般环氧地坪对混凝土基材的要求如下:1、混凝土要求平整密实,强度要求不低于C20;若强度太差,必然影响涂层耐压、抗冲性能及耐久性。

    Now many places use concrete pavement, but also use epoxy flooring to protect the ground, which can very well extend the service life of the ground, then what is the requirement of the epoxy flooring construction on the concrete base material? General epoxy flooring on the concrete base material requirements are as follows: 1, the concrete requirements are flat and compact, strength requirements are not lower than C20; if the strength is too poor, it will inevitably affect. Pressure resistance, impact resistance and durability of the coating.

    2、地面平整度一般要求在2m范围内落差不大于2mm最好用抹光机抹平并收光);如落差较大,则环氧地坪涂层需加厚以减小落差。

    2. Ground smoothness generally requires that the drop within 2m is not more than 2mm. It is better to use a polisher to smooth and collect the light. If the drop is large, the floor coating should be thicker to reduce the drop.

    3、如需涂装的地面处于底层,地下水位较高,则混凝土底层应做好防水处理,避免地下水上升形成的蒸汽压顶起环氧地坪涂层而引起起泡、起壳现象。

    3. If the ground to be coated is at the bottom and the groundwater level is high, the concrete bottom should be waterproof, so as to avoid the bubbling and shelling caused by the vapor pressure caused by the rise of groundwater.

    4、新建混凝土干燥至少3周以上,含水率不高于6%,且在养护干燥过程中避免局部淋雨及地面积水,否则易引起局部混凝土水分含量超标。

    4. New-built concrete is dried for at least 3 weeks, and its moisture content is not higher than 6%. In the process of curing and drying, local raining and surface water should be avoided. Otherwise, local concrete moisture content will easily exceed the standard.

    5、楼板、钢筋混凝土梁等构件上的细石混凝土找平层强度不应低于C20,厚度不低于0mm。

    5. The strength of fine stone concrete leveling layer on floor, reinforced concrete beam and other components should not be lower than C20, and the thickness should not be less than 0 mm.

    6、对损坏的混凝土表面修补或找平时,应采用强度等级不小于C20的细石混凝土,找平厚度不应小于30mm;需用水泥砂浆找平时,应先涂一层混凝土界面处理剂,再按设计厚度找平。当施工过程不宜进行上述操作时,可采用树脂砂浆或聚合物水泥砂浆找平。

    6. For repairing or leveling damaged concrete surface, fine stone concrete with strength grade not less than C20 should be adopted, leveling thickness should not be less than 30mm; for leveling with cement mortar, a layer of concrete interface treatment agent should be coated first, and then leveling according to the design thickness. Resin mortar or polymer cement mortar can be used to leveling when the above operation is not suitable in the construction process.

    7、细节部位,如落水管周围、门槛处等混凝土应平整,棱角应平直。

    7. The details, such as the concrete around the downspout pipe and the threshold, should be level and the edges and corners should be straight.

    8、大面积混凝土基层应根据基材状况切割合理伸缩缝留待地坪涂装时处理,为保持地面美观,尽量将伸缩缝隐蔽在隔断下,若不行,则在环氧地坪施工时留缝,然后用弹性胶灌缝。

    8. Large area concrete base should cut reasonable expansion joints according to the condition of base material and leave them to be treated when the floor is painted. In order to keep the ground beautiful, the expansion joints should be concealed under the partition as far as possible. If not, the expansion joints should be retained during the construction of epoxy floor and then filled with elastic glue.
