High-quality characteristics of modern cement colored tiles
According to research, in Ziyang County, Shaanxi, China's "Hometown of Tile and Slate", slate roofs have been covered with slate for windshield since the pre-Qin period, and many ancient and beautiful slate houses are still well preserved. Due to the backwardness of the processing industry, European and American deep processing of slate has been widely used in building roofs for hundreds of years. From museums, churches to city halls, castles and other high-end buildings, black slate roofs have become one of the symbols of European architecture. . The material of slate tiles is not slate but natural slate (also called slate). Slate is a kind of natural stone like marble, granite, sandstone, etc. Its biggest feature is that it has natural cleavage, which can be used manually or mechanically. It is divided by the way of slabs, so the appearance of the building slate products is not mechanically polished, and it has the characteristics of simple and natural appearance. Due to the different material characteristics and metamorphic effects, some of the high-quality materials in the slate can be processed into roof tiles. These slates are often called tile slates. The slates that cannot be used as tiles are processed into decorative panels and used as walls. Surface and ground modification.
The same is the building slate type. Tile slate can be used as decorative slate, but decorative slate cannot be used as tile slate. What is the reason? First of all, we must know the characteristics of high-quality slate: good splitting performance and flatness. Good temperature, small color difference, high blackness (other colors are the same), high bending strength, low calcium, iron and sulfur content, low loss on ignition, good acid and alkali resistance, low water absorption, and good weather resistance. Without good splitting performance, there is basically no way to split the slate to the standard thickness of 5~7mm; without good bending strength, the application requirements of tiling cannot be met at this thickness; the flatness is poor, and it is basically impossible It meets the requirements of neat and proper hanging tile construction; without good material characteristics, it is impossible to maintain the application life of more than 100 years without fading, weathering, and rust. This is the reason why veneer slate cannot be used as tile slate. Similarly, the reason why tile slate can be used as veneer slate is easy to understand. As long as the tile slate is split a little thicker, it can satisfy all the requirements of veneer slate. Requested.
