Stone surface processing methods

Natural stone surface processing types

1, natural surface (natural surface

Natural surface refers to the use of hammers and other tools will be a piece of stone from the center of the natural split, forming a natural stone surface like extreme unevenness, to maintain the natural mechanism of the stone processing methods. Natural surface is extremely rough, a large number of products used in small square, such as curbstone above.

2, machine cut surface (Machine section)

3, polished surface (Polished surface)

Processing process: test selection - coarse grinding - fine grinding - fine grinding - fine grinding Fine grinding - fine grinding - polishing - inspection: test selection before checking the drawings, check the semi-finished products of the stone type, size and angle limit tolerance is in line with the requirements, and then further inspection Whether the color tone and pattern on the surface to be polished are consistent with the semi-finished products of the same year batch, whether the quality defects such as missing corners, missing edges, cracks, color lines, color spots, etc. are in line with the product quality requirements, and whether there are any oil spots, rust and other contaminations on the surface.

Fine grinding, fine grinding, polishing, in the order of 200 # metal grinding disk, 400 # metal grinding disk, 500 # resin grinding disk grinding. Fine grinding process, be sure to frequently check whether the surface being ground to eliminate the previous grinding disc grinding traces, the previous grinding disc grinding traces have been eliminated, the process is complete. The key to fine grinding is to select a good 500# resin disk.

4, fire surface (Surface fire)

In the granite slab, through the high temperature gas jet (i.e., flame jet method) to process a uniform, rough, brightly colored surface, this plate is known as the fire plate. Its working principle is the use of hot gas flame (flame temperature of more than 20,000 ° K, gas flow rate of 2500m / s) and stone surface contact with the formation of thermal shock, the use of granite in different mineral particles of the thermal expansion coefficient of difference, when the flame jet burns the surface of some of the particles of the thermal expansion of the particles loosened off, the formation of a natural, concave and convexity of no more than 1 ~ 1.5mm undulating and regular rough decorative pattern. Anti-slip effect, due to high-temperature treatment can also play the role of weathering. This surface is mainly used for indoor such as flooring or for commercial building finishes.

5, matte surface (Matt surface)

Matte surface plate is a kind of rough grinding processed by flat and not slippery or diamond saw cut, there is no brightness plate, generally rough grinding to 120 mesh, without fine grinding, grinding and polishing of the latter process, and the effect of the more popular matte furniture similar.

Processing technology and polished plate is more similar, generally by sawing - school thickness - rough grinding - cutting - - grinding chamfering - inspection. -Grinding and chamfering - inspection and packaging - shipping or warehousing. The key is to grasp the number of coarse grinding grinding head, saw saw out of the rough board required coarse grinding process from the beginning of the mesh less, generally from 24 mesh, 36 mesh, 60 mesh, and then to 120 mesh, while the machine cut plate processing of the plate by the 60 mesh and 120 mesh coarse grinding can be processed. The operation method is the same as the light plate polishing process. This kind of plate is widely used in outdoor flooring, elevator entrances, corridors, washrooms and other places, mainly to play a non-slip function. In addition, this kind of product is also used in the decoration of furniture.

6, sandblasted surface (Sand surface)

With stone sandblasting machine to make a craft effect. According to the hardness of the stone to adjust the size of the airflow to achieve the required depth and uniformity.

Product types and main applications:

(1) large wall sculpture, suitable for hotels, restaurants, lobby decoration, exhibition halls, museums, exhibition halls, offices, conference rooms, interior decoration.

(2) Plate engraving, suitable for laying marble, granite plates of high-level buildings inside and outside the walls, inside and outside the ground decoration. Through carving and pattern splicing, it adds changes and vitality to marble and granite plates.

(3) Anti-slip flooring, in the smooth granite surface engraved on the shallow pattern to anti-slip, at the same time with a variety of geometric curves, more beautiful, can be used for awnings, corridors, elevator doors, lavatory and other places need to be anti-slip function of the place.

(4) monument inscriptions, monuments, tombstones, foundation stones, inscriptions, tour guide plates and other text pattern engraving, taken from natural stone, can be permanent without losing beauty.

(5) gifts, with granite, marble and other natural stone shaped processing, and carving process with special text patterns, as offices, home interior furnishings of arts and crafts.

7, antique surface (Antique plane)

As the name suggests is to take the natural marble or granite, etc. to do the old into the old look, according to the hardness of the plate texture to choose the antique water immersion, that is, corrosive liquids, and then it is polished after grinding and polishing and other special treatment, so that it reaches or close to the natural weathering surface. Imitate the stone after a certain number of years of use of the antique effect of the surface processing, is generally used generally with antique grinding brush or antique water treatment, generally antique grinding brush effect and cost-effective some, but also more environmentally friendly.
