Now, all kinds of ceramic tiles have been widely used as the decorative decoration of buildings, and the varieties of ceramic tiles on the market are also changing. At present, there are more and more varieties of ceramic tiles on the market. The water absorption rate of ceramic tiles is relatively low, and the surface Smooth and increasingly large, traditional tile adhesives can no longer meet the requirements of existing products. The emergence of redispersible polymer powder has solved this process problem.
Due to its good decorative and functional properties such as durability, water resistance and easy cleaning, ceramic tiles are widely used: including walls, floors, ceilings, fireplaces, murals and swimming pools, and can be used both indoors and out. The traditional method of pasting tiles is the thick layer construction method, that is, the ordinary mortar is first applied to the back of the tile, and then the tile is pressed to the base layer. The thickness of the mortar layer is about 10 to 30mm. Although this method is very suitable for construction on uneven bases, the disadvantages are low tiling efficiency, high technical proficiency requirements for workers, increased risk of falling off due to poor flexibility of the mortar, and difficulty in checking the quality of the mortar at the construction site. Strict control. This method is only suitable for high water absorption tiles, and the tiles need to be soaked in water before attaching the tiles to achieve sufficient bond strength.
The tiling method currently widely used in Europe is the so-called thin-layer bonding method, that is, a toothed spatula is used to scrape the polymer-modified tile adhesive batch on the surface of the base layer to be tiled in advance to form raised stripes And the mortar layer of uniform thickness, then press the tile on it and twist it slightly, the thickness of the mortar layer is about 2 to 4mm. Due to the modification effect of cellulose ether and redispersible latex powder, the use of this tile adhesive has good bonding properties to different types of base layers and surface layers including fully vitrified tiles with extremely low water absorption. Good flexibility to absorb stress due to temperature differences, etc., excellent sag resistance, long enough open time for thin layers to greatly speed up application, easy handling and no need to pre-wet the tiles in water. This construction method is easy to operate and easy to carry out on-site construction quality control. Redispersible latex powder not only greatly improves the quality of ceramic tiles, but also makes the current ceramic tiles more environmentally friendly and healthy.
