The emergence of each new type of material, while receiving high attention, is also prone to controversy. Accompanied by a variety of doubts or affirmative voices, Yanban has focused many eyes on the building materials industry in the past two years. According to different countries and regions of production, rock slabs are divided into domestic rock slabs and imported rock slabs. Today, I will give you a comparison of the main differences between domestic rock slabs and imported rock slabs.
First of all, what exactly is a rock slab? Some people in the industry believe that the slate is actually a high-end ceramic tile. The composition of rock slabs contains various minerals; among them, the content of silica (quartz), feldspar, and various oxides is higher than that of ordinary ceramic tiles. Therefore, the color of the rock slab is more colorful, and the hardness and strength are also better. However, the production conditions of rock slabs are extremely harsh, and they generally need to be fired in an environment with a high temperature exceeding 1240°C. Because of this, there is no need to worry about the temperature of the general kitchen at all.
In terms of water absorption, the water absorption of rock slabs can be lower than 0.02%, which is almost negligible, while the water absorption of ordinary ceramic tiles is generally between 0.3% and 0.5%. Therefore, the surface of the rock slab is almost 100% waterproof and stain resistant. At present, the maximum slab can be 3200×1600mm. The thickness of the rock slab is very thin, which can be between 3mm-6mm, so the application potential in the home is unlimited.
Although rock slabs have so many advantages, they also have the disadvantage of being relatively expensive. This is also one of the main reasons why rock slabs have not yet been widely promoted. Moreover, generally speaking, in terms of market prices, the selling price of imported slabs is higher than that of domestic slabs. Then, why are imported rock slabs so expensive? Is it necessary for consumers to buy imported rock slabs? What are the differences between domestic rock slabs and imported rock slabs?
On the whole, imported rock slabs and domestic rock slabs have slight differences in hardness, high temperature resistance, surface texture and specifications, but they are basically similar. Currently domestic rock slabs and imported rock slabs use almost the same press equipment, but imported rock slabs have unique formulas and technical advantages such as surface enamel and embryo body. Therefore, compared to domestic rock slabs, imported rock slabs can withstand sudden cold and heat, have a slightly higher hardness, and have a delicate and warm surface texture, and are lighter and thinner.
That being the case, for ordinary consumers, how do they know whether the ceramic tile vendor recommends imported or domestic slabs? No matter which building material store you enter, when you choose, as long as you observe from the side of the slate, there is an obvious transparent enamel layer and the layer of embryonic body layer is imported rock slab, and the integrated layer of embryonic body and enamel layer is domestic rock slab.
