疏松门牌石修补及其翻新

作者: 点击次数:503 发布时间:2019-06-20

目前,采用门牌石装修地面的建筑物很多,部分大理石材质疏松,气孔率与吸水率高,尤其地面在日常走动磨耗、自然风化及门牌石病变等情况下,都会造成板面起毛、爆粒等受损情况。

这次失败的主要原因:该板经腐蚀,已变得疏松。所以要对板材进行加固处理。发现有些加固材料在公司试验还可以,但在现场试效果就不理想。分析发现,在公司做板材容易处理干燥,而在现场即使使用局部加热法烘干板子,待热源一离开,底面和四边的湿气就会很快侵人进来,占据了毛细孔,使加固材料不能渗人到门牌石内部。这样一抛光加固剂就会象撕皮一样剥落下来,起不到加固的作用。在现场施工不可能对大面积板材进行烘干,所以在选择加固材料时,必须选用亲水性好,渗透力强,抛光性好,粘接力强,而不会引起门牌石变色的材料。

以上就是门牌石修补及其翻新的方式,希望会给你一些帮助。
