涂料、油漆涂饰的墙面,涂层成膜后,有时会在局部表面出现发霉起毛,近似一层白霜的现象。严重者造成膜层脱落,影响装饰效果。造成这种现象的原因有三:一是基层潮湿而含碱成份较高,膜层在干燥时,碱份析出表面而形成一层碱霜;二是涂漆时空气较潮湿(相对湿度80%以上),稀释剂水份蒸发慢,在漆膜中凝聚起来;三是使用的涂料或油漆品质不良,耐碱性和对气候的适应能力都很差,
After coating and filming on the wall surface of paints and paints, moldy fluffing may occur on the local surface, which is similar to the phenomenon of white frost. In severe cases, the film peels off and affects the decorative effect. There are three reasons for this phenomenon: First, the base layer is wet and contains a high alkali content. When the film is dry, alkali is precipitated on the surface to form a layer of alkali cream; second, the air is relatively humid when painted (relative humidity is more than 80%). ) Thinner water evaporates slowly and condenses in the paint film. Third, the quality of the paint or paint used is poor, and the alkali resistance and climate adaptability are both poor.
