processing natural stone
Natural stone is widely used in landscaping for paving and decoration in architecture and construction, is used for finishing work, the manufacture of various products.According to rock hardness distinguish the stones high, medium and low strength.Before further use in any field need to be processed.This is achieved by giving the desired shape and appearance is crucial.Please give a stone given size and shape, then move to the textured work on its front surface.
To make the shape and size of the approximation and precise handling.As a result, the approximate workpiece obtained at precision machining products reach the final parameters.For mechanical processing methods include shearing, cutting and demolition hammer.When shearing texture of natural stone turns bumpy, with uniform depressions, bumps or grooves.Impact energy is used to produce products hewn, they reached a point texture.The most common method of treatment is considered to be an exact cutting is performed by shtripsovoy, cable or cutting disc.
to produce architectural and construction details, or monuments of rock high strength, used physical and mechanical processing methods: high-frequency, thermosetting gas burners of various types.Increasingly, the ultrasonic method has been applied decorative treatment, which takes place in an abrasive environment.It is highly accurate, although rather long time.
Textured stone work is performed using different technologies, as a result of the front surface can turn sawn, sanded, polished and polished.These technologies help to unlock the full fine quality natural stone and keep them in continuous operation.Usefulness of a technology in the treatment depends on the strength and structure of the stone, its further operation methods.
Marble
in decorating and manufacturing sites most often used marble, known since ancient times.Its name is translated from the Greek as "shining stone".It is formed of limestone, change its structure under the influence of certain physical and chemical conditions.It consists of marble or calcite, dolomite, and sometimes two of these minerals.
It almost always contains particles of other mineral or organic compounds as impurities that substantially affect the quality marble, increasing or reducing its decorative effect, and coloring.Colored marble has predominantly banded or mottled coloring a wide variety of shades.The structure of the stone and the direction in which it is carried out sawing, is determined by its design.Manifest pattern and color after grinding and polishing.
Regarding marble apply various processing techniques as for the original decorative impart certain qualities and to restore the surface damage associated with continuous operation.Artificial aging of a marble called Antica, it is carried out by means of abrasive brushes or acid.Also for use marble hydroprocessing powerful water jet, sandblasting with quartz crystals or river sand, and manually firing or high-precision machining.
Grinding marble
mechanical process in which the surface of the marble is processed abrasive substances, called grinding.It precedes polishing, making the stone more homogeneous and brighter.With it leveled the overall level of marble slabs on the floor.In this case there is no surface gloss, which is typical for polishing, it is matte, slightly rough and not slippery underfoot.This technique is used both for new products and for the restoration of worn surfaces.
initially held rough grinding , during which the surface is leveled.After that special grinders with coarse abrasive discs carried finish polishing marble .If processed marble slabs for the floor or the tracks, the subsequent polishing they are not carried out, not to make the surface slippery and uncomfortable to walk on.
marble restoration and repair
Despite the strength, as a result of active exploitation, especially in crowded areas, marble can be damaged and break.Even a slight deformation of the spoils drawing surface, making it dull.Therefore, to preserve the splendor and beauty of natural marble patterns require special care and proper cleaning marble.Marble slabs, which are constantly moving people, especially highly susceptible to degradation, they chipped and cracked.These damaged surfaces must be restored in order to preserve the aesthetic appearance and safety of operation.All repair and restoration of marble should pursue professional masters with special devices and tools.This process is to restore surfaces, grinding, and, if necessary, subsequent polishing and polishing.For as long as possible to save the results of the restoration, applied technology crystallization and polymerization.
order to remove traces of coarse abrasives used for grinding, polishing is carried out preliminary surface.To give smoothness and gloss finish polishing is performed.To refresh the polished surface, and extend the service life of products, polishing process is carried out, consists in treating the surface with special chemical compounds.Polished polishing is different from that at the surface of the stone it becomes perfectly smooth but not shiny.Marble, thus treated, is used for flooring and external cladding.For the protective treatment of stone used polymerization process, comprising the sealing surfaces to prevent ingress of dirt and fluids.
Crystallization marble
Polishing, made by a special chemical composition, strengthens the structure of marble and help improve the wear resistance is called crystallization.This thermo-chemical process performed on finished products or surfaces that were in active use.With it you can change the structure of the stone, to increase its resistance to mechanical stress and pollution, to make the structure firmer and brighter in color.
crystallizer are powdered or liquid consistency weakly acidic substances.They can be sprayed over the surface of a special low-speed single disc machine.When processing changes the chemical structure of the surface of the marble on her tightened cracks and scratches, enhanced gloss, increased wear resistance of the outer space.Crystallization of marble recommended regularly, without waiting for the loss of gloss.On the marble floors in crowded places, such as train stations, crystallization and polished marble daily.
Timely repair and restoration of marble products from this beautiful mineral, prevent the destruction of the stone!Replacement marble, significantly more expensive restoration of the integrity and gloss coating of marble and other dolomite rocks.
