Polished porcelain, also called kerogranite, is an artificial finishing material made by semi-dry pressing technology. In this case, a press powder is used, which is affected by a pressure of 500 kg / cm 2 . At the next stage, the raw material undergoes firing at a temperature of 2300 ° C. It is also worth mentioning that the press powder is obtained from a slip. The last ingredient includes several components that determine the quality characteristics.
Description
Polished porcelain stoneware is a material that is processed to a mirror shine. This process is notable for its complexity and duration, which is what determines the higher cost of this material compared to the matte variety. However, the surface of the finish looks much more impressive. In the process of abrasion, the layer coarsens, polished porcelain stoneware becomes dull. Among other things, polishing reveals closed pores, so the material is stained with pigments. If this is not so, then immediately after the acquisition it is recommended to coat the surface with wax or varnish.
Main types
Polished porcelain is classified as a material that can be made by various methods. The first involves the manufacture of a simple pressing method. In this case, the initial mass is subjected to pressure, as a result, it is possible to obtain a finish related to the salt / pepper series.
Another type of unglazed porcelain stoneware is a material made using double pressing technology. After the initial treatment, a heterogeneous mixture with additives is applied to the plate, the layer thickness of which is from 2 to 4 mm. As a result, it is possible to create a pattern on the surface of the tile, which is again subjected to pressing. By this technique, material belonging to a series of texture or marble-like granite is made.
Varieties of porcelain stoneware by composition of raw materials
If you need polished porcelain tile (600x600), then you can choose a material that is of the “salt / pepper” type. It is characterized by a uniform color and small inclusions that are evenly distributed throughout the volume of the slab. The most common of this type are shades:
- beige;
- gray;
- blue;
- green
- pink.
Porcelain stoneware is found, which is of the “soluble salt” type. In this case, a soluble salt is applied to the base of the plate, which interacts with the base and creates a pattern on the surface. The technology is common in China, so this material is known as polished Chinese porcelain.
Ceramic granite can also be manufactured using the Monocolor technique, which involves the use of a large number of mineral additives and dyes. As a result, it is possible to obtain a homogeneous colored mass, which is compressed. Depending on the quantity and quality of mineral additives, the depth, as well as the saturation and intensity of a particular color, is achieved. Using this technology, white polished porcelain tiles are made. However, it may have other colors, for example, gray or black. The most expensive are blue and red tiles.
Application area
Porcelain stoneware can be used to finish different surfaces indoors or outdoors. This material is an ideal floor covering for rooms in which floors are exposed to high mechanical stresses. These include shopping malls, train stations, airports, metro and shops. Porcelain tile (600x600) polished can be used for decorating private interiors, namely halls, kitchens, corridors and hallways.
This material is perfect for lining surfaces in pools and bathrooms, as well as in the working areas of restaurants and cafes. Quite often, such coatings can be found in garage workshops, as well as in car washes. Surely in your city you have encountered facades that are equipped with hinged technology using porcelain stoneware.
Manufacturers
If you are interested in polished black porcelain, then you can purchase it in the store of the corresponding goods. Today, many companies offer such products for sale. As an example, we can consider the Russian manufacturer of the ZKS, which is engaged in the production of porcelain stoneware. The products of this company have been known since 2005. When creating the material, exclusively imported dyes are used, and high-tech equipment allows you to create a high-quality coating that differs not only in traditional patterns, but can also be covered with multicolor ceramic glazes. Another, no less well-known manufacturer, is Ural Granite, which calls itself the leader in the production of porcelain stoneware. This is a company offering many collections for every wallet and taste.
According to users, this product is characterized by high aesthetic and operational qualities, it has a wide area of use and can be combined with any products of other manufacturers. As a floor covering, for example, you can choose square tiles with a side of 300 mm, while products for ventilated facades are made in a wide variety of sizes, including 1200 x 600, 1200 x 295, 600 x 600, 600 x 300 mm.
By the way, porcelain stoneware (600x600) polished you can buy not only in the described companies, but also in Euro-Ceramics, which is a relatively young manufacturer, but honors the traditions of manufacturing the described products. The history of the plant began in 1968, today the company boasts rich experience in the production of its products.
Consumer Reviews
As buyers mention, porcelain stoneware is not only strong and durable, but can also undergo mechanical stress. There are no scratches on the surface. You can not worry that the lining will be worn over time. Porcelain tile is not exposed to temperature and humidity. As users mention, if you lay it in compliance with the technology, then it will stay on the walls and floor for several decades.
Conclusion
Polished porcelain can be made using MDR technology, which allows to obtain a heterogeneous mass filling the volume of the slab. In the production according to this method, multi-colored powder is used, which differs in composition. Using this technology, it is possible to achieve the effect of natural marble streaks and blackout.
