由于環(huán)氧地坪漆是施工在混凝土基面上一層薄薄的涂膜，混凝土地面的狀況直接決定了施工后環(huán)氧地坪的質(zhì)量。一般來(lái)說(shuō)，環(huán)氧地坪漆施工要求混凝土強(qiáng)度在C25以上，要求表面不起砂，硬度要好，不存在起砂、空鼓起殼現(xiàn)象。那么針對(duì)混凝土地面空鼓起殼現(xiàn)象如何處理呢?下面環(huán)氧地坪漆廠家就給大家詳細(xì)介紹?；炷粱婵展钠饸さ奶幚矸椒ǎ?/p>

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: 在環(huán)氧地坪漆工程中，常用的除油方法包括表面活性劑清洗法、火焰燃燒法、拋丸法等，對(duì)于環(huán)氧地坪漆基面大面積空鼓起殼，需要進(jìn)行銑刨處理，吧空鼓其余全面清除，再重新用水泥砂漿或混凝土抹面。對(duì)于小面積的空鼓起殼，將空鼓處切縫或灌注環(huán)氧樹(shù)脂漿料，空鼓處切割去除，重新澆注水泥砂漿或用無(wú)溶劑環(huán)氧砂漿修補(bǔ)。

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.

混凝土基面空鼓起殼的預(yù)防方法：

Preventive methods of empty heave shell on concrete base surface:

1、注意結(jié)合層施工質(zhì)量。

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

(1)結(jié)合層在素水泥調(diào)漿后應(yīng)均勻涂刷，不宜采用先撒干水泥后澆水的掃漿方法，素水泥漿水灰比0.4-0.5為宜，刷素水泥漿應(yīng)與攤鋪面層混凝土緊密配合。

(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)嚴(yán)格做到隨刷隨鋪。

(2) Strictly follow the brush with the shop.

(3)鋪設(shè)面層時(shí)，如果素水泥漿已風(fēng)干硬結(jié)，則應(yīng)鏟去后重新涂抹。

(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)在水泥爐渣或水泥石灰爐渣墊層上涂刷結(jié)合層時(shí)，宜加砂子，其配比可按水泥：砂子為l：l。刷漿前，應(yīng)把表面松動(dòng)的顆粒掃除干凈。

(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、嚴(yán)格處理墊層。

2. Strict treatment of cushion.

(1)認(rèn)識(shí)清理墊層表面的浮灰、漿膜以及其它污物，并沖洗干凈。如底層表面過(guò)于光滑，則應(yīng)鑿毛。

(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)控制基層平整度，用2米直尺檢查，其凸凹度不應(yīng)大于10毫米，以保證面層厚度均勻一致，防止厚薄懸殊過(guò)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)面層施工前1-2天，應(yīng)對(duì)基層認(rèn)真進(jìn)行澆水濕潤(rùn)，使基層具有清潔、濕潤(rùn)、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.
