Extraction of granite, we believe that will not be unfamiliar, with the continuous improvement of people's living standards, people's requirements for the decoration is also more and more high, more and more stringent requirements for their own living environment, so the use of granite in the decoration is more and more frequent. The use of granite for decoration makes the effect of decoration more beautiful and atmospheric. So by many people's favorite. Most of the current market is the use of marble decoration indoor, granite decoration outdoor, a brief introduction to the advantages of granite.

Comparative analysis of the advantages and disadvantages of stone granite

Stone granite is abundant in Dali, Yunnan, it is high compression resistance, small water absorption, easy to clean, meticulous texture, is a higher level of indoor floor decoration materials. General family in the decoration can choose about 100-200 yuan per square meter stone granite.

Granite has the advantages of wear-resistant, good frost resistance, weathering resistance, corrosion resistance, beautiful color and so on. Family floor decorated with granite, can make the room noble, elegant, show luxury. But it is more expensive, the general household can choose each to square meters about 200-300 yuan varieties. The disadvantage of stone granite is in the environment will soon and air moisture, carbon dioxide reaction, so that its surface loses luster, become rough.

The difference between stone granite and marble

1, according to the cause of the stone is divided

Granite belongs to the igneous rock, igneous rock is mainly formed by volcanic material, such as magma. Liquid magma below the surface cools and solidifies. Mineral gases and liquids penetrate the rock and form new crystals and various colors. They are usually dark in color. Natural granite is igneous rock, also known as acid crystallization of deep-rock, is the most widely distributed in the igneous rock, belongs to the hard stone, rock hard and dense, according to the size of its crystalline particles can be divided into "pegmatite", "coarse" and "fine" three kinds of crystals.

Marble belongs to the metamorphic rock metamorphic rock is in the high temperature and high pressure and the role of the mixture of minerals from a stone naturally metamorphosed into another kind of stone. Metamorphism may be recrystallization, texture change or color change. Natural marble is the original rock in the earth's crust through the role of high temperature and high pressure within the earth's crust to form the metamorphic rock. It is a medium-hard stone, mainly composed of calcite, limestone, serpentine and dolomite. Usually have obvious pattern, mineral particles are many.

2, according to the hardness difference

Stone hardness to Mohs hardness as a unit of calculation, Mohs hardness in 6-7 belongs to the hard stone, such as granite, Mohs hardness in 3-5 belongs to the hard stone, such as marble, Mohs hardness in 1-2 for the soft stone, such as limestone and dolomite.

3, the chemical composition of the distinction

Marble belongs to the carbonate stone, its main component is calcium carbonate-based, accounting for more than 50%, and other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. Usually have obvious pattern, many mineral particles. Granite is mainly composed of quartz, feldspar, hornblende, pyroxene, olivine and black mica, belongs to the silicate class of stone, its composition is dominated by silicon dioxide, accounting for about 65% to 75%.

After a brief introduction to the above, we should have a more detailed understanding of granite, granite and marble in the decoration compared to its cost-effective, decorative effect is also better, so now many people will use granite decoration, compared to marble decoration, granite has a high degree of hardness, frost resistance, good performance, not easy to weather, so it will be used to decorate the interior! The effect is very good, in the purchase is to choose according to their own needs. I hope the above will help you.
