What are the main surface treatment methods of decorative stone, and what are their applicable scopes?

There are eight main methods for stone surface treatment:

1, polishing: high-gloss surface. Polishing may or may not last for a long time, depending on the type of stone. Granite, marble and limestone are usually polished and need different maintenance to keep their luster.

2. Polishing: The polished surface looks "soft" with obvious scratches, so it doesn't need much care. Marble, limestone and slate are all suitable for polishing.

3. Pickling: There are small corrosion marks on the surface. There are fewer scratches on the pickling surface, and the appearance is simpler than that on the polished surface. Most stones can be cured, but the most common ones are marble and limestone. Pickling is also a way to soften the luster of granite.

4. Axe: The surface is not smooth. After preliminary cutting, the stone is further processed to eliminate obvious saw marks, but the effect can not reach the effect after polishing. Granite, marble and limestone can all be treated in this way, usually in the case of customization.

5, fire: the surface is rough. This kind of surface is mainly used indoors, such as the ground or as the facing of commercial buildings, and the labor cost is high. After high temperature heating and rapid cooling, the combustion surface is formed. The burning surface is usually granite.

6. Cracking: The surface is rough, but not as rough as burning. This surface treatment is usually hand-cut or chiseled in a mine to expose the naturally cracked surface of the stone. This surface treatment is mainly used for slate.

7. Rolling: the surface is smooth or slightly rough, and the corners are smooth and broken. There are several ways to achieve the effect of tumbling. The machine can roll 20 mm bricks or 3 cm bricks, and then split them into two pieces. Marble and limestone are the first choice materials for tumbling treatment.

8, brushing: the surface is old. The treatment process is to scrub the stone surface and imitate the natural wear effect of stone.

Generally, the luminosity of stone can be 80-90 degrees, and some stones can even be above 100 degrees, but some stones can't be polished, and at most they can only be matt.

Generally speaking, the higher the luminosity, the higher the price. Polished surfaces are usually used for plane curtain walls, indoor walls and floors. Especially in some high-end buildings, indoor walls and floors require high luminosity. Its special film has high luminosity and strong reflection on light, which can fully show the colorful colors and natural textures of stone.

The action of fire can burn off some impurities and low melting point components on the stone surface, thus forming a rough finish on the surface, which will have a certain tingling sensation to the touch. The processing of burnt noodles has certain requirements on the thickness of stone to prevent the stone from being broken during processing. Generally, the thickness is required to be at least 2CM, and some stone materials are required to be higher.

In addition, some materials will change color during combustion, such as rust stone (G682), and the burnt rust stone will show a certain reddish color instead of the original yellow rust color. Burning surface is characterized by rough and natural surface, no reflection, fast processing speed and relatively cheap price, and is often used for dry hanging of external walls.

The natural surface formed by barrel grinding is extremely rough, which is widely used in Little Square, kerbs and other products.
