建筑墙体表面常见环氧地坪漆涂装问题

作者:admin 日期:2018-10-24 12:37:57 人气:63

  

现代建筑墙体大多数是由水泥混凝土组成的。水泥混凝土可分为素水泥混凝土和钢筋水泥混凝土。素水泥混凝土是由水泥、砂、石和水组成钢筋混凝土是由水泥、砂、石和钢筋组成。多孔性引起的环氧地坪漆涂装缺陷。由于水泥混凝土建筑墙体的多孔性,过多过快吸收了湿涂层的水分,导致湿涂膜的黏度急剧增大,缩短了湿涂膜的流动时间,失去了流平的机会,最终引起刷痕和环氧地坪漆涂膜失光等涂装缺陷的产生。

Most of the walls of modern buildings are made of cement concrete. Cement concrete can be divided into plain concrete and reinforced concrete. Plain cement concrete is composed of cement, sand, stone and water reinforced concrete is composed of cement, sand, stone and steel. Defects caused by porous coating on epoxy floor paint. Because of the porosity of cement concrete wall, excessive and rapid absorption of moisture in the wet coating, resulting in a sharp increase in the viscosity of wet coating, shorten the flow time of wet coating, lost the chance of leveling, eventually lead to brush marks and epoxy floor paint coating matting defects. 碱性引起的环氧地坪漆涂装缺陷。水泥混凝土墙体的碱性强,其强碱与湿涂膜中的某些不耐碱颜料发生反应,导致涂膜发花、变色等涂装缺陷的产生。

Alkaline coating defects on epoxy floor paint. The alkalinity of cement concrete wall is strong, and its strong alkali reacts with some non-alkali-resistant pigments in the wet coating film, which results in coating defects such as blooming and discoloration of the coating film.

含水率引起的环氧环氧地坪漆涂装缺陷。在水泥混凝土墙体的含水率过高时进行涂料施工,一方面因墙体吸收涂料量变少而导致涂膜薄;另一方面由于墙体的水分稀释了涂料,降低了涂料的黏度和固体含量而导致流挂等涂装缺陷的产生。水泥混凝土墙体的含水率过低时,墙体吸收环氧环氧地坪漆湿涂膜的水分过多而引发刷痕和失光等涂装缺陷。

Defects of epoxy floor paint caused by moisture content. When the water content of the cement concrete wall is too high, the coating is thin because the amount of the absorbed coating becomes less; on the other hand, the water of the wall dilutes the coating and reduces the viscosity and solid content of the coating, resulting in the appearance of coating defects such as sagging. When the water content of the cement concrete wall is too low, the wall absorbs too much water from the epoxy floor paint wet coating, which results in brush marks and gloss loss.

渗透压引起的环氧环氧地坪漆涂装缺陷。地板漆在地下水丰富的地区施工时,地下水渗透压力过大,引起地下室或一楼水泥地面渗水,轻则导致地板涂膜起泡,重则导致环氧地坪漆涂膜脱落。

Penetration defects caused by epoxy floor paint. When floor paint is used in areas with abundant groundwater, the groundwater seepage pressure is too high, which causes water seepage in the basement or the cement floor of the first floor, lightly causes foaming of floor paint, and heavily causes the film falling off of epoxy floor paint.
