如果认真观察一些使用多年的建筑物,就会发现有不少外墙出现麻面脱皮、表面坑洼不平、麻孔密布等现象。进行外装饰时,由于砖面酥散脱皮,容易使抹灰大块脱落。这种现象严重影响了建筑物的结构强度,同时也影响了建筑物的外形美观。 If you look carefully at buildings that have been in use for many years, you will find that there are a lot of phenomena such as pock-skin peeling, uneven surface, and thick holes in the outer wall. When the exterior decoration is performed, the plaster is easily peeled off due to the peeling of the brick surface. This phenomenon has seriously affected the structural strength of buildings and also affected the aesthetic appearance of buildings.
