Natural stone processing, including the rock sawing, cutting, grinding, drilling, polishing and other processes. As far as plate processing is concerned, it is mainly sawing. According to the different stone processing technology, it can be divided into special-shaped products (including carving, arc plate, hollow column, solid column, line, parquet, etc.), plate products (including large board, specification board, sheet, etc.). According to the use of parts, it can be divided into indoor stone, outdoor stone; Wall (facade) stone, ground stone; Building stone (such as bridge piers), decorative stone (such as various decorative panels), etc.
There are many methods for the surface treatment of stone, which can be used according to the actual needs of users or combined with the pursuit of natural, ancient, and actual efficiency of architectural decoration. The rough surface treatment of the stone is to adapt to this concept, and the following common boards have been introduced:
Natural Split Surface
Natural split surface is also called cracked surface: its surface is rough, but not as rough as fire. This finish is usually done by hand cutting or in a mine chisel to expose the natural cracked surface of the stone. Natural surface refers to the use of hammer and other tools to naturally split a stone from the middle, forming a shape such as the extreme uneven surface of natural stone, to maintain the natural mechanism of the stone processing method. The natural surface is very rough, and it is widely used in small blocks, roadside stones and other products.
Sawn Surface
When stone processing, the stone surface effect generated by the natural cutting machine. It is cut directly by the equipment such as circular sawing sand saw or bridge cutting machine, and the surface is rough with obvious machine cutting lines. The machine section basically does not produce brightness, so it can not reflect the actual color and pattern of the stone.
Polished Surface
The polished surface is also called the polished surface or mirror, the stone surface is very smooth, highly polished, high gloss, and has a mirror effect. The polished surface refers to the flat surface, polishing the stone surface with resin disk and polishing disc, so that it has a mirror luster of the plate, the general stone luminosity can be 80, 90 degrees, which is characterized by high luminosity, strong reflection of light, can fully display the rich gorgeous color and natural texture of the stone itself. Polishing surface processing process: test selection -- rough grinding -- fine grinding -- fine grinding -- polishing -- inspection.
Flamed Surface
On the granite plate surface, through high temperature gas injection (i.e. flame injection method) processing a uniform, rough, bright color surface, this plate is called the fire plate. Its working principle is the use of hot gas flame (flame temperature of more than 20000°K, gas flow rate of 2500m/s) and stone surface contact formed thermal impact force, the use of different mineral particles in granite thermal expansion coefficient difference, when the flame spray its surface part of the particles thermal expansion loose off, Form a natural, convex degree does not exceed 1~1.5mm fluctuation and regular rough decorative pattern. It has a non-slip effect and can also play a role in weathering resistance due to high temperature treatment. This surface is mainly used for interior such as floors or as a finish for commercial buildings.
Honed Surface
Honed surface plate is a kind of rough grinding and not smooth or cut with diamond saw, there is no brightness of the plate, generally rough grinding to 120 mesh, without fine grinding, fine grinding and polishing after several processing, and the more popular matte furniture effect is similar. Matt processing process and polished plate is more similar, generally by sawing - thickness - rough grinding - cutting - edge grinding chamfering - inspection packaging - shipping or storage.
Sandblast Surface
A kind of process effect made by stone sandblasting machine. The airflow size can be adjusted according to the hardness of the stone to reach the required depth and uniformity. Sandblasted panel is a kind of plate with various patterns formed by sandblasting on the basis of light plate. Its principle is the use of marble, granite plate light and rough surface color, light hao contrast, carved out a beautiful, elegant, natural pattern, is in marble, granite plate on the basis of finishing, is also a new thinking of decorative materials industry. It is integrated with art, making the value of marble and granite itself greatly improved. The types of processing can be divided into two types: intaglio (deep engraving of the pattern part) and Yang engraving (convex part of the pattern, deep engraving of the rest).
Antique Surface
As the name suggests, it is to take natural marble or granite and other old into an ancient look, according to the hardness of the texture of the plate to choose antique water immersion, that is, corrosive liquid, and then after grinding and polishing and other special treatment, so that it can reach or close to the natural weathering surface. The surface processing that mimics the antique effect of stone after a certain number of years is generally treated with an antique grinding brush or antique water, and the effect and cost performance of the antique grinding brush are generally higher and more environmentally friendly. Antique noodles are divided into (1) Flamed+ Brushed: fire first and then antique processing. (2) Pickling and antique (Pickling+ Brushed) : First pickling and then antique processing.
Waterjet Surface
Also called water flushing surface, a high pressure water jet stone surface, causing the mechanism of treatment. With high pressure water directly impact the stone surface, peel the soft texture of the component, forming a unique decorative effect.
Brushed Surface
Also known as water brush surface antique. The treatment process is to scrub the surface of the stone to mimic the natural wear effect of the stone.
bush hammered Surface
Use alloy knife to make a tool, artificial or machine hit the stone surface jump skin, so that the surface is rough, a little uneven; Or use a chisel to cut small holes densely on the surface, intentionally imitating the effect of water droplets dripping on the stone for years. It has a non-slip effect on the ground, deepens the rough and thick feeling in the wall, absorbs light and heat, has no large area reflection, and increases the three-dimensional sense.
Pineapple Surface
Using an alloy knife to make a tool, artificial or machine hit the stone surface to jump skin, making the stone surface more uneven than lychee processing, just like the skin of pineapple.
Mushroom Surface
Generally, artificial cleaving is used, and the effect is similar to natural cleaving, but the sky surface of the stone is a plateau shaped shape with a depression around the middle. The surrounding teeth are clear, and the natural surface of the middle is fully raised, so that it has a rich three-dimensional and stable sense of firmness.
Tumbled Surface
The surface is smooth or slightly rough, the corners are smooth and broken. There are several ways to achieve the tumbling effect. 20mm bricks can be rolled in the machine, and 3cm bricks can also be rolled and then split into two bricks. Marble and limestone are the preferred materials for tumbling treatment.
