Is The Higher The Hardness Of Ceramic Tiles, The Stronger The Wear Resistance?
2022/6/16 19:33:59

Ceramic tiles can protect the cement floor and various pipes on the ground, and also have a good decorative effect. If the floor of the house is paved with tiles, the whole room will become very bright and clean. Generally, the wear resistance of ceramic tiles is divided into 5 levels, and the wear resistance of different levels is different. So the higher the hardness of ceramic tile, the more wear-resistant it is? What are the parameters for buying ceramic tiles? Follow Hanse to understand the specialty of ceramic tiles!

Is The Higher The Hardness Of Ceramic Tile, The More Wearable It Is?

When choosing ceramic tiles, some people always think that the harder the ceramic tiles are, the better, because hard indicates that the ceramic tiles have good wear resistance, so they will choose which one has high hardness. In fact, high hardness ceramic tiles only represent the quality of ceramic tiles, which has nothing to do with the wear resistance of ceramic tiles. In the same category and within the same specification, heavier ceramic tiles are naturally better than lighter ones, because heavier ceramic tiles have higher density. However, the thicker the tiles, the better the quality. The hardness is related to the density of the brick. Drop water on the back of the brick to see how fast it absorbs water. If the speed is very fast, the hardness is low. The slower the water absorption, or even the better the non water absorption, the higher the hardness.

How To Know The Wear Resistance Of Ceramic Tiles?

The wear resistance can not be determined by the senses alone, but depends more on some technical indicators. When the tiles leave the factory, they will be tested. Similar to the grinding wheel against the ceramic tile, the abrasion resistance of the ceramic tile is tested under the condition of thousands of revolutions. Generally, the abrasion resistance of ceramic tiles is divided into 5 grades.

Grade I wear resistance is the lowest, and it is generally used for display, walls and places with less activities. The abrasion resistance of grade II ceramic tiles is greater than that of grade I ceramic tiles, which are mainly used in bathrooms, bedrooms and other environments without hard friction. The wear resistance of grade III is moderate. It is mainly used in places with a large amount of activities. Such as living room, kitchen, etc. High wear resistance at grade IV. It is very suitable for use in corridors, corridors and public areas of luxury residences. There is no clear concept of grade V division. But theoretically, it has super wear resistance, and is generally used in non household environments, such as airports, stations, etc.

What Are The Parameters For Buying Tiles?

1. Hardness of tiles. Ceramic tiles are hard and durable. Polished bricks are generally grade 7, glazes are generally Grade 5-6, microcrystalline stones are generally grade 5, and porcelain chips are generally grade 3-4.

2. Water absorption of tiles. Water absorption determines the antifouling performance of ceramic tiles. The water absorption of ceramic tiles will be very high, generally around 20%, with a minimum of 5-10%. The water absorption of ceramic tiles is relatively low, generally below 5%, and now many glazed tiles have glazes on their surface, which absorb water. The ratio is less than 0.1%.

3. Flatness of tiles. The evenness of the polished glaze is slightly worse than that of the polished brick, and the antique brick is also worse than that of the polished brick. It is generally recommended to leave seams when selling tiles in specialty stores. According to the national standard, it is qualified if the error is within ± 0.5%. (polished ceramic tiles ± 0.2%, maximum deviation not exceeding 2mm, other ceramic tiles ± 0.5%).

4. The tiles are wear-resistant. 150 is a low level. The wear resistance of domestic first-line brands is generally below 130, and the good varieties reach 110. 150 is equivalent to the quality of third tier brands. The higher the wear resistance value, the worse the wear resistance of ceramic tile. The ceramic tiles laid in public places should stand the test of time, and the wear resistance must be less than 120.

5. Anti slip performance of ceramic tiles. If the friction water absorption is greater than 0.5, it is a safe and qualified product.

Why Choose Ceramic Tile With High Hardness?

The hardness directly affects the service life of ceramic tiles, which is particularly important. You can use the method of knocking to listen to the sound. The crisp sound indicates that the internal quality is good and should not be deformed and broken. Now the tonnage of press in the market ranges from 200 to 16800 tons, which directly determines the density and hardness of ceramic tiles.
