Moisture proof performance is an important technical index to judge plastic floor. PVC plastic floor with bad moisture resistance is bound to be warped when moisture enters after long-term heat evaporation, which will cause damage to PVC plastic floor. The high quality PVC plastic floor adopts high density base material, its moisture-proof performance is very good, and the water absorption thickness expansion rate is far less than the national standard. In addition, special wear-resistant layer, decorative paper and balance layer can seal the base well to ensure the overall moisture-proof performance of PVC plastic floor is better.
Three quality seven points in the installation of PVC plastic floor industry has always been said, PVC plastic floor is three points, PVC plastic floor seven points installation (that is, the quality of the installation determines the quality of PVC plastic floor 70%). The unsatisfactory use of PVC plastic floor is caused by the poor laying of PVC plastic floor to a large extent. The problem of PVC plastic floor pavement has become a persistent disease restricting the use of PVC plastic floor.
To avoid unpleasant PVC plastic floor maintenance, more importantly, do a good job in the sales. Before the installation of PVC plastic floor, the staff must make four different measurement preparations, which can lay a good foundation for the later construction.
Intermittent ventilation can exhaust moisture. In rainy days, doors and windows facing south or Southeast (i.e. the direction of upper wind) shall be closed as far as possible, and only doors and windows in the downwind direction shall be opened to reduce water vapor entering the room. When the weather is sunny, all doors and windows can be opened to accelerate evaporation of water.
