Polished tile is a kind of shiny brick made by polishing the surface of the general brick body, a kind of general brick, relative to the general brick, polished tile surface to be much brighter, polished tile is hard and wear-resistant, suitable for use in most indoor spaces other than the bathroom, kitchen, such as for balcony, exterior wall decoration, etc., on the basis of the use of infiltration technology, polished tile can make a variety of imitation stone, imitation wood effect.

Comprehensive Understanding Of Polished Tile - Polished Tile Development, Classification, Advantages And Disadvantages, Selection

The development of polished tiles

Polished tile with the production technology level continues to improve, quality in the world's forefront, quality in the international advanced level. The national standard is higher than the European standard, the surface flatness, side straightness, straight angle and wears resistance and other parameters are higher than the European standard by more than 2 times. Process requirements are higher than foreign small-size tiles, in seamless splicing, for tile size accuracy requirements are also higher, and the quality is also more excellent. Polished tiles account for a large share of exports, but by oversized tiles by the environment, strength, and breakage rate, there will be no greater development. In order to seek change, ceramic enterprises in science and technology to make great efforts to improve the performance of polished tiles, so that polished tiles with breakthrough innovation.

Classification of polished tiles

1. infiltration type polished tile

Infiltration type polished tile is the most basic type of product, these products are very common, and almost all manufacturers are doing. The production process is also very simple, is in the blank body is applied to a layer of bleeding glaze, in the surface layer of about 5mm, and then after two polishing, trimming, chamfering, and then do antifouling treatment can be a factory, it should be noted that this last process ---- antifouling agent, some manufacturers of antifouling treatment is very good, with an imported antifouling agent, but some manufacturers use is very cheap, without antifouling, with wax Do treatment.

2. micro powder tile

In the surface of the blank and sprinkle a layer of finer powder, the blank and the surface of the raw materials used are the same, that is, the surface of the powder and after a long time ball mill again, and then the powder with a scraper scraped on the blank, and then pressed once. The surface layer of fine particles directly brings the benefit of the possibility of low water absorption, the ability to prevent infiltration, but also depends on the brand, some small manufacturers do micro powder tile water absorption rate is also very high, and the ability to prevent seepage is also very low.

3. multi-tube fabric polishing tile

Multi-tube fabric polished tile product production process is relatively special, powder material under the material is by many material tubes once under the material once pressed into shape, these products are very natural colour pattern, each piece of brick are generally similar, these products have a little problem, your choice is relatively small, only a very few large manufacturers produce.

4. polished tile through body

Through the polished tile in the production, brick surface and brick embryo for the same powder cloth powder, through the press out of the brick embryo, direct polishing treatment, due to the high cost of raw materials, now few factories to do through the body, there are some factories will do to choose a few to do through the body of the polished tile, more for pure colour series polished tile.

5. microcrystalline stone

Microcrystalline stone in the market later emerged products, its characteristics are the following, the main thing is basically absolutely no seepage of dirty things, his water absorption rate is basically equal to zero, the thickness can basically be compared with 3 ordinary polished tiles.

It is a combination of two layers of material pressed products, the surface layer is a layer of glass, glass, of course, does not absorb water, but also has its weaknesses, is not wear-resistant, a long time will be sand with the shoe abrasion, sand = quartz, its Mo-style hardness is much higher than the glass, glass can not stand the friction of sand.

With the continuous development of microcrystalline stone process and technology, colour products from time to time rich, has become an independent series, now the market said polished tile has not included microcrystalline stone, and full glaze antique tile, from the process of full glaze also has to polish this a process, but because the general full glaze production, is the antique tile production line plus a polishing process to produce, so now full glaze is classified as antique tile.

The advantages of polished tiles

1. No radioactive elements: natural stone is a mineral, without high-temperature sintering, so contains individual trace radioactive elements, long-term contact will be harmful to humans, polished tile without radioactive elements.

2. Basic control no colour difference: natural stone due to rock formation time, rock depth different colour difference, polished tile by carefully blended, the same batch of products consistent colour, basically no colour difference.

3. Bending strength: natural stones due to natural formation, formation time, weathering, etc. are not the same, resulting in the degree of compactness, and strength; polished tiles by thousands of tons of hydraulic press, and then by more than 1200 ℃ high-temperature sintering, high strength.

4. Tile thin, lightweight: natural stone because of the low strength, so the processing thickness is larger, increasing the load weight of the floor building, forming a potential threat, cost increases, and increased transportation, paving and other difficulties.

5. Anti-slip: ground tile safety anti-slip is important, especially for families with elderly children more important tile anti-slip effect. The polished tile surface is bright and shiny, many consumers believe that its non-slip effect is poor, in case of spilled water increased the safety risks, so avoid it, had to choose the "light introverted" matte tiles. In fact, all the polished tiles are non-slip, if the tiles have soil will be slippery, and there will be water instead of astringent, so as long as good daily cleaning is not affected by its anti-slip effect. In the anti-slip performance, polished tile and matte tile is the same.

The disadvantages of polished tiles

1. Since it is polished, the problem also comes, because the smooth, bright, so it is not dirty, with the dunnage dragged after, will leave a watermark, because your dunnage can not be 100% clean, like wiping glass, so if you want to wipe clean, it is more effort.

2. Colour liquid easily infiltrated, the simplest test is to take a pen to write a few words on the surface of the brick, poor polishing turn, write immediately after wiping away, are not necessarily clean, the handwriting may have infiltrated, good brand, because the press is good, high density, coupled with the firing temperature is high, very high density, so it is not easy to infiltrate. Of course, now there is a new process called super clean bright, which is in the polished tile surface in throwing on a layer of liquid glaze, on the anti-fouling ability is greatly enhanced, the anti-slip ability is weakened, while the polished tile surface super clean bright glaze layer also has a certain time limit to maintain.

How to choose polished tiles? 

1. See

Look at the brick colour uniformity, and surface finish, check whether there are defects such as colour difference, deformation, lack of edges and corners; at the same time along the edge of the brick look over, check whether the edge of the brick repair is straight, there is no bending; brick back that the bottom embryo is white, there is no factory name or pavement arrow, colour is uniform.

2. Knock

In the purchase can be used to hand or hard object knocking tiles, if the sound is very crisp, like the sound of knocking metal, it means that the tile porcelain and high density, internal quality, high hardness; if the sound sounds like knocking the sound of the board, it means that this brick has cracks inside, quality problems. As the tile is to be laid on the floor, people will step on it for a long time, if the hardness is not high, there will be a floor fracture.

3. Drip

Tile stain resistance is also consumers must pay attention to when buy tiles, if the tile stain resistance is not good, sprinkle some juice or ink on it can not be cleaned, it will be very affected the appearance. Selection can be coloured drops of water (such as ink) on the front of the tile, rest for a minute after wiping with a damp cloth, if the tile surface leaves traces, it is said to have dirt sucked into the brick; such as the brick surface is still bright as a mirror, the tile does not absorb dirt, easy to clean, brick quality is good.

4. Measure

The higher the accuracy of the tile edge length, the better the effect after tiling, buy quality tiles is not only easy to construct, and can save time and auxiliary materials. Use a tape measure to measure the size of each tile around there is no difference, high accuracy for the top quality.

5. Row

Tile with good hardness, and toughness, is not easy to break for the best. Scratch each other with the corners of the tile debris, view the broken fragments of the fracture as dense or loose, is brittle, hard or loose, soft, is left scratched, or scattered powder, such as the former that is good the latter that is poor.
