Stone: present situation and Prospect

The present situation of stone in the world

There are many kinds of building decoration materials. Stone, plastic, ceramics and other building materials have been widely used. Although plastics and ceramics occupy part of the stone market, stone is still the first choice for building decoration engineering because of its unique natural advantages.

Red, yellow, green, black, blue and white stone will still be valuable varieties, and some flexible varieties will also be welcomed.

With the continuous pursuit of stone quality by stone manufacturers, along with the improvement of fire prevention requirements, the progress of installation technology and the light pollution of glass curtain wall, stone as the decoration method of curtain wall will be the trend of the times.

The trend of international stone consumption shows that the world's stone products have become more and more thin. In the 1980s, the thickness of stone was 10 mm to 15 mm; In the 1990s, the thickness of stone was reduced to less than 8 mm. After Italy produced 6.5 mm granite face brick, Sweden produced 4 mm thick stone face brick. At present, there is only 3 mm thick marble board market. The biggest advantage of ultra-thin board is light weight. It can be fixed on the wall with ordinary adhesive, and support the ultra-thin board at the same time

The stone resources are saved and utilized effectively.

According to the statistics of foreign stone industry, in 2005, the world's stone consumption reached 878 million square meters, and the demand for raw materials reached more than 8000 tons; in 2010, the consumption of stone materials reached 1.186 billion cubic meters, and the demand for raw materials reached 108.6 million tons. It is estimated that in 2015, the consumption of stone materials will reach 1.6 billion square meters, and the demand for raw materials will reach 146.7 million tons in 2015. Stone consumption will reach 4 billion square meters. Among them, marble accounts for 50%, granite accounts for 45%, and the rest 5% is sandstone, slate, basalt, limestone, Manau rock, etc.

Present situation and Prospect of stone in China

At present, the two important decorative materials are stone and ceramics. In the field of building decoration materials, the market share of ceramics is the first and the stone is the second. Both of them occupy an important market share. Some data show that the current market share ratio of ceramics and stone is 6:1, and ceramics occupy an absolute dominant position. However, the market of ceramic decoration materials has been shrinking year by year in recent years, while stone materials are increasing year by year.

Natural stone resources have the characteristics of non renewable, with the increasing demand and the increasing shortage of resources, natural stone products have a larger appreciation space.

In recent years, the average annual growth rate of stone consumption is more than 9%, and the increasing trend of stone consumption year by year does not decrease. China's stone consumption has been in the forefront of the world, the economic crisis has caused a certain impact on China's stone export, but it has not had a great impact on the whole stone industry.

Compared with stone, the main advantage of ceramics is that its thickness is relatively thin, the price is low, and the energy efficiency is similar to the beauty of natural stone design and color, and there are few color differences and defects. If stone can break through the heavy defects and achieve the same thickness as ceramics, that is, thin stone and ultra-thin stone, the development of natural stone will be improved.

If the thin and ultra-thin stones can develop rapidly, the application scope of stones will be expanded, such as high-rise office buildings, commercial center residential buildings, which will be a very huge market. Before the production of China's slate is generally 12-20 mm, all kinds of days

However, the thickness of stone and ceramic is generally 6-12mm. Compared with ceramic, the weight of natural stone in the same area is more than 2-3 times, which affects the decoration of stone in high-rise buildings. Production of thin plate stone, unit resource consumption can produce more stone plate, compared with the current processing level, the cost can be reduced a lot, so as to enter the ordinary home decoration market.

From the defects of stone itself, it will become an important factor in the development of stone industry to reduce the thickness of natural stone plate, reduce the weight of unit area, reduce the unit price, adapt to the consumption level of the general public and expand the application scope of stone, and the thin and ultra-thin type of stone just solves these two important problems.

Let's look forward to the development of stone technology, add bricks and tiles on the road of stone development, and make joint efforts to make it more advanced!
