环氧地坪漆混凝土基面空鼓起壳如何解决?

由于环氧地坪漆是施工在混凝土基面上一层薄薄的涂膜,混凝土地面的状况直接决定了施工后环氧地坪的质量。一般来说,环氧地坪漆施工要求混凝土强度在C25以上,要求表面不起砂,硬度要好,不存在起砂、空鼓起壳现象。那么针对混凝土地面空鼓起壳现象如何处理呢?下面环氧地坪漆厂家就给大家详细介绍。混凝土基面空鼓起壳的处理方法:

Because the epoxy floor paint is a thin coating on the concrete base, the condition of the concrete floor directly determines the quality of the epoxy floor after construction. Generally speaking, the construction of epoxy floor paint requires concrete strength above C25, requires no sand on the surface, good hardness, no sand, empty shell phenomenon. So how to deal with the phenomenon of empty shell of concrete floor? The following epoxy floor paint manufacturers will give you a detailed introduction. The treatment method of empty bulging shell on concrete base surface: 在环氧地坪漆工程中,常用的除油方法包括表面活性剂清洗法、火焰燃烧法、抛丸法等,对于环氧地坪漆基面大面积空鼓起壳,需要进行铣刨处理,吧空鼓其余全面清除,再重新用水泥砂浆或混凝土抹面。对于小面积的空鼓起壳,将空鼓处切缝或灌注环氧树脂浆料,空鼓处切割去除,重新浇注水泥砂浆或用无溶剂环氧砂浆修补。

In floor paint engineering, the commonly used degreasing methods include surfactant cleaning, flame burning, shot blasting, etc. For the large area of floor paint base surface bulging, milling treatment is needed, the rest of the bars are completely removed, and then the cement mortar or concrete surface is re-applied. For a small area of empty drum shell, the hollow drum is cut or filled with epoxy resin slurry. The hollow drum is cut and removed, and the cement mortar is re-poured or repaired with solvent-free epoxy mortar.

混凝土基面空鼓起壳的预防方法:

Preventive methods of empty heave shell on concrete base surface:

1、注意结合层施工质量。

1. Attention should be paid to the construction quality of the joint layer.

(1)结合层在素水泥调浆后应均匀涂刷,不宜采用先撒干水泥后浇水的扫浆方法,素水泥浆水灰比0.4-0.5为宜,刷素水泥浆应与摊铺面层混凝土紧密配合。

(1) The bonding layer should be uniformly coated after plain cement slurry mixing. It is not suitable to use the method of sweeping cement by spraying dry cement before watering. The water cement ratio of plain cement slurry is 0.4-0.5. The plain cement slurry should be closely combined with the concrete of paving surface.

(2)严格做到随刷随铺。

(2) Strictly follow the brush with the shop.

(3)铺设面层时,如果素水泥浆已风干硬结,则应铲去后重新涂抹。

(3) When laying the surface layer, if the plain cement slurry has been air-dried and hardened, it should be shoveled off and re-smeared.

(4)在水泥炉渣或水泥石灰炉渣垫层上涂刷结合层时,宜加砂子,其配比可按水泥:砂子为l:l。刷浆前,应把表面松动的颗粒扫除干净。

(4) When the bonding layer is coated on the cement slag or cement lime slag cushion, sand should be added. The proportion of sand can be determined by cement: sand is l:l. Before brushing, the loose particles on the surface should be cleaned up.

2、严格处理垫层。

2. Strict treatment of cushion.

(1)认识清理垫层表面的浮灰、浆膜以及其它污物,并冲洗干净。如底层表面过于光滑,则应凿毛。

(1) Understanding and cleaning the floating ash, serous film and other dirt on the surface of cushion, and rinsing them. If the bottom surface is too smooth, it should be chiseled.

(2)控制基层平整度,用2米直尺检查,其凸凹度不应大于10毫米,以保证面层厚度均匀一致,防止厚薄悬殊过大。

(2) Control the smoothness of the base and check it with a 2-meter ruler. The convexity and concavity of the base should not be greater than 10 mm, so as to ensure uniform thickness of the surface layer and prevent excessive thickness disparity.

(3)面层施工前1-2天,应对基层认真进行浇水湿润,使基层具有清洁、湿润、粗糙的表面。

(3) 1-2 days before the construction of the surface layer, the grass-roots should be watered and wetted carefully, so that the grass-roots has a clean, wet and rough surface.
