Ceramic tile not only depends on its appearance but also on its quality

2019-01-04

Many consumers are always confused about the price gap between online and physical stores. Why is there so much difference, just because of brand? How to distinguish inferior ceramic tile?

Xiaobian wants to tell consumers that ceramic tiles which are less than one fifth of the price of physical stores on the Internet are basically not qualified products. Brand is part of the reason for the high price, and the real reason is the quality of ceramic tiles themselves. The following small edition to teach you how to distinguish between good and bad ceramic tile bar.

Tile hardness

The hardness of ceramic tile determines the wear resistance of ceramic tile. Everyday life will cause varying degrees of wear and tear on ceramic tile surface. Insufficient tiles and even scissors can scratch the surface. Testing method of ceramic tile hardness: using Mohs hardness tester to test, if there is no professional instrument, you can use nails, scissors, coins, etc. to knock on the surface of ceramic tile, force sliding. If no scratches are left, the hardness of the ceramic tile is qualified. In addition, this method is not suitable for microcrystalline.

The thicker the tile, the better the quality.

When people buy tile, they like to weigh it in their hands. The thicker or heavier the tile, the higher its strength and the better its quality. In fact, this view is one-sided, although strength and thickness are related, but the strength in essence depends on the quality of ceramic tiles, rather than blindly through thickening to protect. According to the national standard, the fracture modulus index reflecting the strength of ceramic tile should be more than 32Mpa, while the European standard EN176 should be more than 27Mpa, and the product quality standard should be more than 38Mpa on average. Now, the ceramic tile has also sprung up thin-plate ceramic tile. The quality is still good, so don't judge the quality of tile by its thickness.

To see the quality of a piece of glazed tile, it is necessary to see whether the glazed texture is clear and smooth. Whether there is defect or not, high-quality products require at least 95% of the brick distance from 0.8m to observe the surface vertically without defect. Qualified products are required to observe the surface vertically at a distance of 1 m from the brick without defects. Common ceramic defects are pinholes, bubbles, spots, dirt, brown eyes, corrugated, pattern, color difference, cracks, glaze touching, angle collapse, etc. The difference between high-quality products and qualified products is deformation and surface quality. And poor quality products, surface texture is not smooth, there will be pinholes. Chromatic aberration and other phenomena.

Measure smoothness

Ceramic tiles with poor smoothness will appear empty drum and fall off after laying. Therefore, when choosing and purchasing tile, we must select it carefully. Ceramic tiles of different packing boxes of the same brand can be laid flat on the ground. Good ceramic tiles are relatively flat. There are no gaps or very small gaps when they are laid flat together. When they are broken, there are suctions between them. Ceramic tiles of poor quality have gaps in the middle, and they are easy to be damaged when weights are pressed down.
