Advantages and Disadvantages of Polished Tiles

Advantages of Polished Tiles

1, first, no radioactive elements: natural stones are mineral substances, without high temperature sintering so that they contain trace amounts of radioactive elements. Prolonged exposure to natural stones is harmful to the human body; polished tiles will not cause harm to the human body; 2, second, basically color difference can be controlled: natural stones suffer serious color aberration due to diagenesis time as well as rock strata's different chromatic shades. Polished tiles are elaborately mixed so that products of the same assignment have the same design and color, basically without color aberration; 3, third, high bending strength: due to differences of natural formation, forming time, weathering, natural stones have different densification levels and strength; polished tiles are made by pressing of thousands of tons hydraulic press, and then by high temperature sintering of more than 1200 ℃ so that they are of high strength; 4, fourth: polished tiles are thin and light: because of low strength, natural stones are thick and heavy after processing, which increases the load of floor building, makes a potential threat, rises costs, and increases transportation, paving and other difficulties. 5, fifth, polished tiles are anti-skidding: it is important for floor tiles to be safely anti-slip. In particular homes with the aged and children pay more attention to tiles anti-slip effect. Polished tiles' surface is so bright and clean that many consumers think their anti-slip effect is weak. If there is water on the tiles, it will be more dangerous. Thus consumers avoid it like the plague, but choose matt tiles. In fact, all polished tiles are anti-slip. If there is soil on the tiles, they will be slippery while if there is water on the tiles, they will be hard-going. So keeping daily cleaning will not affect their anti-slip effect. On the anti-sliding performance, polished tiles are the same as matte tiles.

Critical Defect of Polished Tiles

Due to their hardness, wear resistance, and suitability for indoor and outdoor large-area pavement, polished tiles are popular among consumers. However, pores left on the polished tiles during production will hide dirt and dust, causing pollutants infiltration to tile surface. Even some tea sprinkled down on the polished tiles, they cannot be saved. Perhaps the tile industry has been aware of that, then some high-quality polished tiles have been added an antifouling layer when leaving factories. But this layer of antifouling makes polishing tiles losing their effect of vetrified tiles. There is also a method in fitment industry that wax before construction to prevent sticking dirt. Now countries with top antifouling technology for polished porcelain tiles are Italy, Spain and other European countries. And anti-fouling technology has become a required course for good polished tile products.

Detailed Introductions for Tile Production Process

China has brilliant achievements in ceramics production

China is a large ceramic production country, which has a long history and brilliant achievements in ceramics production. Foshan has become the powerhouse of the development of Chinese ceramics, which has brought together many leading ceramic brand companies, such as the new source, Dongpeng, Hemei ceramic, Bode tiles, etc. Do you know about the production process of polished tiles? Because there is little difference in the production process of the major companies, now we'll take Hemei as an example to introduce details about tile production process for everyone.

Detection before Tile raw material being put into use

The tile quality is largely depended by the quality of raw materials, so the tile raw materials must pass the detection of production workshop before being put into use. Usually the detection is mainly ignition loss, absorption rate and shrinkage rate. For added raw materials, there are basic mud and chemical materials. According to Hemei tile production workers, the basic types of Hemei tile products are roughly the same, of course, each series of the products also contain a special mud. As for the chemical material, the various pigments are used for the production of different colored tiles.

The formation process of the raw materials to tiles

The qualified tile raw materials after being tested will officially enter production. The first production process is grinding balls and making pulp, the general milling time is about 12 hours. The longer milling time is, then the finer particles. Subsequently, the stirrer will continuously stir, and the stirred slurry is atomized into fine droplets and to be evaporated to a powder. After the powder is made, it may discharge and produce at any time, which is pressed into tiles by the press machine. But usually the actual size of the pressed out ceramic floor tiles is larger than the specification size, this is because the tiles will shrink in the firing process.
The process from the tile to the finished product

It needs a series of steps from the finished products after the general shape of the tiles is completed. Because moisture content of tiles made by the press is high, it is likely to cause the tile chapped, deformation and other defects if carrying out glazing print and directly firing into the kiln. It must go into the drying kiln to be dried to reach qualified moisture content. In this case, glaze using centrifugal rejection glaze, pressure (water jet) spray enamel and bell leaching glaze. Then, firing by the kiln is followed. Different companies have different kiln time, take Hemei tile for example, the firing time is about 70-80 minutes and temperature is 1200℃. Fired tiles need milling, chamfering and polishing. The last step is grading. The grading generally has amount deformation, quality sorting, size detection and color separation processes. At this point, the tiles have been finished.

Development of China's Polished Porcelain Tiles

History Background of Porcelain Tile

Ever since several centuries, the adornment effect of the porcelain tile is improved with the improvement of production methods of porcelain tile. For example, in Islamic period, all the adornment of the ceramic tile in the Persian period reached its peak time. Then, the use of ceramic tile becoming popular all over the world, in many states and cities, the production and adornment of ceramic tile got to its top. In the historical course of ceramic tile, the mosaic of Spain and Portugal, the floor tile of Italian Renaissance, glazed tiles of Antwerp, the development of ceramic tile illustrations of the Netherlands and ceramic tile of Germany all are the meaningful landmarks. In ancient times, the polished tiles are made by hand, that is, each piece of polished tile is manual forming, colored by hand, so every piece of ceramic tile is a unique work of art. Polished ceramic tile is used in almost every aspect of the construction, such as: wall, ground, ceiling, fireplace, frescoes and the outer walls of buildings. Now, in the world scope, ceramic tile is no longer made by hand, and colored by hand, but use automation production technology, the person's hand is only used to install the ceramic tile. And as in the past, people use ceramic tile for indoor and outdoor decoration.

Development of China's Polished Tiles

With the fast improvement of polished production technology in our country, the quality of our polished ceramic tile are leading the world, all quality have reached the international advanced level. The national standard are higher than the European standard, the parameters such as surface smoothness, edge straight degree, straight angle and wear resistance are two times higher than the European standard. The process requirements is smaller than the foreign specification, as for the seamless, the ceramic tile of China also has higher dimension accuracy requirements than the European tiles. At present, the export of polished porcelain tiles is accounting for a large market share. But the large specification ceramic tile is difficult to have bigger development by the limitation of environment and strength, and the influence of the damage rate. In order to change, ceramic enterprises improve themselves in science and technology under the great strength, so as to improve the polished ceramic tiles performance and innovation.

China Ceramic Tile Market Development

According to accepted data, the annual output of China ceramic tiles has reached 3.4 billion square meters, it accounts for about half of the global total ceramic amount. With the improvement of personal income and appreciation grade, Chinese high-end ceramic tile product deman expands unceasingly. In addition, with the investment and increasing of infrastructure and residents' housing construction, and along with the steady growth of GDP, ordinary people are also increasing their income, and begin to stress and pay attention to adornment housing, so the building materials such as ceramic tile is rising for commodities, the future ceramic tile market has a wide development prospect.
