The vitrified (porcelain) brick is made of quartz sand and mud in a certain proportion, and then polished and polished without polishing. The surface is as smooth and translucent as the glass mirror. It is the hardest of all tiles, and it absorbs water. Rate, edge straightness, bending strength, acid and alkali resistance are superior to ordinary glazed tiles, polished tiles and general marble. The vitrified brick is a kind of bright brick which is polished by the surface of the whole body brick body, and is a kind of whole body brick. Ceramics with a water absorption of less than 0.5% are called vitrified bricks, and polished tiles with a water absorption of less than 0.5% are also vitrified bricks.
What is the difference between vitrified tiles and glazed tiles?
What is a glazed tile? A glazed tile is a brick that has been glazed on the surface of the brick. The surface is made of glaze, and the main body is divided into clay and porcelain. The back of the clay is red, and the back of the porcelain is grayish white. The surface of the glazed tile can be made into various patterns and patterns, which are richer in color and pattern than the polished tiles. Because the surface is glaze, the wear resistance is not as good as that of polished tiles.
In terms of hardness, glazed tiles are more than 0.5% water absorption, and vitrified bricks are less than 0.5%. The glazed brick has a low porcelain content, but the surface is sprayed with enamel, so it is beautiful and has good antifouling properties; it is mainly used on the kitchen wall. Vitrified brick is full-tile, high hardness and wear-resistant. It is not easy to appear surface damage for a long time, and its performance is stable. It is mainly used for living room floor and bathroom wall. (What are the common quality problems with glazed tiles?)
From the non-slip, the glazed brick is more colorful in terms of color effect, anti-slip and anti-slip, but the wear resistance is worse than that of the vitrified brick. The long-term use of the surface may be worn out; the vitrified brick is more porcelain and the surface is hard and wear-resistant. Long-term use performance is stable and cleaned (it is better to use wax before use to improve anti-fouling). The anti-slip performance of the vitrified brick is slightly weaker than that of the glazed brick. When choosing, pay attention to testing its anti-slip performance, and pour the water test on the tiled surface.
Advantages and disadvantages of glazed tiles
Advantages: Mainly rich in texture and color. Good antifouling performance. The glaze is a very dense substance, and the dirt cannot enter the inside.
Disadvantages: In the process of firing, cracks, bends, and chromatic aberrations on the glaze are often seen.
In terms of price, because the vitrified bricks are much higher in material, performance and process than the glazed tiles, the price is generally more expensive than the glazed tiles. There is also a retro brick glazed tile, the surface texture treatment is more excellent and beautiful, and the material is more vitrified than ordinary glazed tiles.
What is the difference between vitrified tiles and polished tiles?
Ceramics with a water absorption of less than 0.5% are called vitrified tiles, also known as all-ceramic tiles. The water absorption of polished tiles is 0.5%, which is also a vitrified brick. It is characterized by high-tonnage press and super-high temperature sintering at 1250 degrees.
The vitrified tiles are mirror polished to obtain polished tiles. The early polished tiles have not met the specific requirements due to the water absorption rate. Perhaps it is the industry's intention. Perhaps it is the intention of the industry. Because of the relatively high water absorption rate, there is a fatal flaw: easy Dirty, this is caused by the obscuring pores left by the polished tiles during polishing and polishing. These pores will be contaminated, so that the polished tiles will become stained, and even some tea will fall on the polished tiles. Therefore, in the market, there will be a misleading statement that “the polished tiles are poor and the vitrified tiles are goodâ€. However, with the improvement of tile manufacturing technology and surface treatment technology, the antifouling ability has been further improved. For the rough surface of the whole brick, the polished brick is much cleaner. Polished tiles are hard and wear resistant and are suitable for use in most interior spaces except washrooms, kitchens and indoor environments. Polished tiles can be used to create a variety of imitation stone and wood-like effects. Perhaps everyone realized this, and later some quality polished tiles were added with an anti-fouling layer at the factory. Common specifications for polished tiles are 400x400mm, 500x500mm, 600x600mm, 800x800mm, 900x900mm, 1000x1000mm.
On the market, vitrified tiles, vitrified polished tiles, and polished tiles have the same water absorption rate and are actually similar products. The lower the water absorption rate, the better the degree of vitrification, and the better the physical and chemical properties of the product. Vitrified brick refers to the physical and chemical properties of the brick, while polished brick refers to the polishing process after the finished product.
Characteristics of vitrified tiles
1. The color is bright and soft, and there is no obvious coloration. Natural granites have large chromatic aberrations due to diagenesis time and depth of rock formation.
2. High-temperature sintering and complete porcelain formation produce various crystals such as mullite, which have stable physical and chemical properties, strong corrosion resistance and strong anti-fouling properties, and have a long history. Because of the natural composition, the granite has different time and weathering degree, resulting in different density and strength. After two years of use, it gradually loses its luster, and its appearance is rough and worn, which is difficult to clean and affects the elegance.
3. The thickness is relatively thin, the flexural strength is high, the brick body is light, and the building load is reduced. The natural granite is low in strength and light in weight, which adds to the load of the building and brings a series of hardships to the transportation and paving process.
4. No harmful elements. Granite is a natural mineral that has been buried deep in the earth's crust for a long time. It is not sintered at high temperature, so it contains trace radioactive elements. If it is exposed for a long time, it will be harmful to the health of the body.
Matching skills of vitrified tiles
1. Before paving, the skin to be applied or the ground should be treated first. The foundation layer of the dry-laid method can reach a certain hardness to lay the brick. When the paving is applied, the joint is adjusted between 2-3 mm.
2. It is recommended to use 325 cement, dry-laid method participation ratio: base layer: cement: fine sand = 1:3, pasting layer; cement: fine sand = 1:2. (White series polished tiles are recommended for white cement to achieve a color effect). Pre-staining anti-fouling wax before polishing the tile can improve the anti-pollution ability of the brick surface.
3. The pattern of the mosaic is obvious, please look for the uniform direction of the mosaic features, the pattern features are not obvious or no pattern, please combine the construction effect requirements.
4. After the paving is completed, the cement stains remaining on the bricks should be wiped off in time. The paved ground needs to be maintained for 4-5 days to prevent local unevenness caused by external forces.
