使用软的(或硬的)聚氯乙烯板(简称PVC,下同)作地面防腐层有一定的实用价值。这种防腐蚀方式具有良好的耐腐蚀性能,适用范围很广。同时还有结构致密不渗漏,长期吸水率低于0.5%,施工和维修都方便,材料易得,价格低廉等许多优点。但由于长期以来都是采用大面积平铺法施工,封闭不严,特别是墙柱等转弯处更无法封闭,常常漏液影响使用。因此,通常只是作为临时性的辅助地面。
The use of soft (or hard) PVC sheets (abbreviated as PVC, the same below) as ground coating has some practical value. This anti-corrosion method has good corrosion resistance and has a wide range of application. At the same time, there are many advantages such as dense structure, no leakage, long-term water absorption less than 0.5%, convenient construction and maintenance, easy availability of materials, and low price. However, due to the long-term use of large-area tile construction, lax closure, especially the corners of the wall and other columns can not be closed, often affect the use of leakage. Therefore, it is usually only used as a temporary auxiliary ground.
