What is the hardness of tiles? What is the hardness of ceramic?

The differences between fully glazed floor tiles and microcrystalline stone are as follows:

1. Microcrystalline stone is composed of ceramic bricks and glass-ceramic, and the combination of the two layers can be clearly seen from the side. A piece of microcrystalline stone, the surface is smooth, delicate, and the gloss is very high, and the visual effect of laying out is very rich, but its surface will be easier to scratch than the other three kinds of bricks. If you want to use microcrystalline stone in your home, it is best to use it as a wall decoration.

2. From the side, you can clearly see that the full glaze is composed of a very thin surface grapefruit surface of the ceramic brick because it is a 3D inkjet printing texture, so its brick surface pattern is very diverse, but its flatness is not as good as polished brick and microcrystalline stone, we can go straight to the flatness of the brick surface through the light. The reason is that the firing temperature of a good full glaze is very high, and the bricks are very soft and easy to deform when they come out of the kiln. Therefore, when paving, the requirements for the master's craftsmanship will be higher.

3. Tile hardness is the most important parameter, which will directly affect the service life of tiles, which is particularly important. The most simple way is to use the method of tapping to listen to the sound, and the crisp sound indicates that it is internal, and it is not easy to deform and break; Chromatic difference and size can be judged according to the intuitive, to see whether the color of a batch of tiles is roughly the same, whether it can be better put together, and the color difference is small and the size is regular.

4. The Mohs hardness of polished tiles is in 6-7 grades. Due to the high gloss of the surface of microcrystalline stone tiles, reaching about 90%, but the strength of microcrystalline stone tiles is not high, as a common decoration material in the interior, the surface layer is easy to scratch.

The hardness of ceramic tiles is generally judged by Mohs hardness, and the Mohs hardness range of ceramic tiles is generally between 3 and 8 grades, and the hardness of tiles produced by different manufacturers is different, which is related to the water absorption rate of ceramic tiles, the thickness of the powder, the glaze used, the firing temperature, the firing time, etc.

Full glaze, microcrystalline stone: about 5-6 grades;

Polished bricks, glazed antique bricks: about 6-7 grades;

Unpolished antique bricks: over level 7.

It should be noted that it does not mean that the higher the Mohs hardness of the tile, the better, as long as the hardness of the tile reaches the standard Mohs hardness, in addition, we should try to choose big brand products, and the quality and after-sales are more guaranteed.

The hardness is related to the pressure of the tile, and the pressure of 7,200 tons produces the brick, reaching 8 degrees on the Mohs scale.

Ceramic tiles, also known as tiles, are refractory metal oxides and semi-metal oxides, through the process of grinding, mixing, pressing, glazing, and sintering, and form an acid-alkali resistant porcelain or stone, etc., building or decorative materials, called ceramic tiles. Its raw materials are mostly mixed with clay, quartz sand and so on.

Common sense of tiles. 1.The surface of the full-body brick is not glazed, and the material and color of the front and back are the same, so it is named full-body brick.

2.Full-body brick is a kind of wear-resistant brick, although there are varieties such as seepage bricks, but relatively speaking, the color of full-body bricks is not as good as glazed bricks. As the interior design is more and more inclined to plain design, so the whole brick has become more and more fashionable, the whole body brick is widely used in the hall, aisle and outdoor walkway and other decoration projects on the ground, generally less will be used for the wall, and most of the non-slip bricks belong to the whole brick.

3.The common specifications of full-body bricks are 300x300mm, 300x600mm, 400x400mm, 500x500mm, 600x600mm, 800x800mm and so on.

4.Advantages: Due to the rough surface, the wear resistance and slip resistance are the best of all ceramic tiles.

Disadvantages: Its unique structure determines the texture and effect of the whole brick, and the decorative effect is poor.

The hardness of ceramics is Mohs hardness.

Ceramics is a general term for pottery and porcelain, but also a kind of arts and crafts in our country, far away in the Neolithic Age, our country has a rough style, simple painted pottery and black pottery. Pottery and porcelain are different in texture and nature.

Pottery is made of clay with high viscosity and strong plasticity as the main raw material, which is opaque, has fine pores and weak water absorption, and the sound of hitting is turbid.

Porcelain is made of clay, feldspar and quartz, translucent, non-absorbent, corrosion-resistant, hard and tight tire quality, and brittle knock sound. China's traditional ceramic arts and crafts, high quality and beauty, with a high degree of artistic value, famous in the world.

Features of ceramic

Traditional ceramics, also known as ordinary ceramics, are products fired with natural silicates such as clay as the main raw materials, and modern ceramics are also known as new ceramics, fine ceramics or special ceramics.

Traditional ceramic products include daily-use ceramics, building and sanitary ceramics, industrial art ceramics, chemical ceramics, electrical ceramics, etc., with a wide variety and different properties. With the rise of high-tech industry, various new special ceramics have also been greatly developed, and ceramics have increasingly become excellent structural materials and functional materials.

They have higher temperature resistance, mechanical properties, special electrical properties and excellent chemical resistance than traditional ceramics.

Shake it up. The heavier the same specification and the same type of tile, the higher the density, the greater the force of the press, and the higher the hardness of the tile.

Draw a line. Tiles with high hardness are more wear-resistant, after obtaining the consent of the merchant, you can take a sharp hard object on the surface of the tile to scratch, if you leave scratches, it means that the hardness of the tile is low, if you scratch it, and there are no obvious scratches, it means that the hardness of the tile is high.

First: knock it, listen to the sound, the more crisp the sound, the higher the hardness, secondly, the hard tile is more wear-resistant, if you can, you can take a hard object on the surface of the tile scratch, if there is a deep scratch immediately, it means that the hardness is not enough.

Second: the hardness of ceramic tiles is not the harder the better, everything has a degree, the hardness of ceramic tiles is considered to be of good quality in four or five grades, like the hardness of domestic first-line brands Asia ceramic tiles in grade five, and most of the ceramic tile hardness in grade four.

The hardness of ceramics is Mohs hardness.

Zirconia ceramic.

The hardness of the tool is very high, and the hardness test report of the 3Y zirconia of the cutter gives the data is greater than 9, second only to diamond.

The statement is correct, the hardness definition of diamond should be 10, and the hardness of crystal should be about 7, which is not as hard as zirconia.

Features of ceramic

Ceramics have the performance advantages of high chemical stability, high temperature resistance, high strength, wear resistance, corrosion resistance, high compressive strength, good electrical insulation performance, and good biocompatibility, but ceramics have high brittleness and tensile strength.

Low and poor machinability. Put the metal with easy processing, impact resistance, ductility.

It has the advantages of good and strong deformability.

The combination of ceramics and metals, two materials with different properties, will have a wide range of applications in the fields of wear resistance, vacuum insulation isolation, electrical feedthroughs, voltage-resistant insulation packaging, and signal feed-through of implantable health devices.

The hardness of ceramics is Mohs hardness.

Mohs hardness is a standard for expressing the hardness of minerals, also known as Mohs hardness. It was first proposed in 1822 by Frederich Mohs, a mineralogist from the Spleen Country. is a standard used in mineralogy or gemology.

Mohs hardness is to use the scoring method to mark the surface of the tested mineral, and measure the depth of the scratch, the depth of the scratch is the Mohs hardness, represented by the symbol hm, and also used to indicate the hardness of other materials.

The hardness (scoring method) is expressed by the depth of the measured scratch in ten grades: 1. Talc (minimum hardness), 2. Gypsum, 3. Calcite, 4. Fluorite, 5. Apatite, 6. Orthoclase, 7. Quartz, 8. Topaz, 9. Corundum, 10. Diamond.

The hardness of the measured mineral is determined by comparing it with the standard mineral in the Mohs scale scale. Although the measured values of this method are rough, they are convenient and practical. It is commonly used to determine the hardness of natural minerals.

The hardness value is not an absolute hardness value, but a value expressed in the order of hardness.

Extended information: The Mohs hardness standard is arbitrary and cannot be used precisely to determine the hardness of a material, e.g. the actual hardness difference between grade 10 and grade 9 is much greater than the actual hardness difference between grade 2 and grade 1. However, this classification is useful for mineralogists working in the field.

In daily life, you can use the scratches of the following objects to roughly grasp the hardness.

1) Those who can scratch on paper are equivalent to Mohs 1.

2) Graphite, ** for Mohs.

3) Nails, amber, and ivory are Mohs.

4) Copper and pearl are Mohs 3.

5) Steel is Mohs and teeth are Mohs 5 6.

The hardness of the tile is related to the tonnage of the press, the press is a machine that presses the brick-making material into shape, and the tonnage of the press is related to the density of the tile, that is to say, the hardness of the brick pressed by the press with a large tonnage is higher, and the ceramic tile produced by the press of 7200 tons can reach 8 levels on the Mohs scale, which is very resistant to scratching, even if the steel knife is used to scratch on the surface of the tile, it is not easy to leave scratches.

The following are several common ceramic tile hardness standards for reference:

Full glaze, microcrystalline stone: about 5-6 grades;

Polished bricks, glazed antique bricks: about 6-7 grades;

King Kong glazed tiles: about the grade;

Unpolished antique bricks: over level 7.
