At present, the two major decorative materials in the world are stone and ceramics. Among them, in the field of architectural decoration materials, the market share of ceramics is the first, and the stone is ranked second. Both occupy an important market share. However, data shows that the current market share of ceramics and stone is 6:1, and ceramics dominates. However, the market for ceramic decorative materials is shrinking year by year, and the stone is increasing year by year. In recent years, especially after entering the 21st century, the average annual growth rate of stone usage is more than 9%, and the trend of increasing stone usage is increasing year by year.
Although the global economy has begun to decline, China's real estate has also fallen into a trough, and the domestic stone industry has entered a cold winter. On the surface, it seems that the stone industry has closed down and the layoffs are coming. However, driven by the Shanghai World Expo and the Guangzhou Asian Games, and driven by the country's investment in domestic demand, it will quickly drive the consumption of building materials and drive the development of the stone decoration industry in the present and future years. This will help our stone industry to recover as soon as possible and continue to develop. After all, the use of stone in our country has always been in the forefront of the world. In the past few years, there have been many projects under construction. The current economic crisis has not had a certain impact on China's stone exports, and it has not had much impact on the entire stone industry. Moreover, many foreign merchants who originally purchased from Italy, Turkey, Brazil, India and other countries have also turned to China for procurement, and some foreign small and medium-sized merchants who originally purchased directly from the local countries also avoided the intermediate rewards and directly purchased them like producers.
It can be foreseen that with the sustained and steady development of the national economy, the space for the development of the domestic stone industry will be larger and the momentum will become stronger. On the other hand, in recent years, the rapid development of the ceramic tile industry has largely mimicked the varieties of natural marble and granite, and its color and luminosity are quite realistic compared with natural stone, especially the artificial stone series. So, for this reason they still occupy a large part of the market share of stone decorative materials. Compared with stone, the main advantage of ceramics is that the thickness is relatively thin and the price is low. It can imitate the beauty of the natural stone color, the color difference and the flaw are few, and it has the luxurious and high-grade decorative effect.
However, if we compare them in detail, no matter how beautiful the work of ceramic materials and artificial stone is, compared with natural stone, the direct feeling, comfort, gorgeousness, etc. give people a feeling of insufficiency, not as natural stone texture, beauty innocence, Simple, high-end, luxurious and so on. If the stone can break through the thick defects and achieve the same thickness as the ceramic, namely thin stone and ultra-thin stone, the use and development of the stone will be further improved. Like the current economically developed regions of China and the developed countries in the West, the demand for stone, especially for thin stone, is still very large. Moreover, the order quantity of thin and ultra-thin stone materials from abroad over the past years and the rapid development of thin and ultra-thin stone processing industries in the southeast coast of China, Shandong, Jiangsu, Dalian and the Mainland can be seen if China's thin and super If the thin stone can develop rapidly, it will expand the application range of the stone, for example, it can enter the high-rise office building, commercial center and residential building, which will be a very huge market. Like the stone plates produced in China before, they are generally all kinds of natural stone from 12mm to 20mm, and the thickness of ceramics is generally 6mm~12mm. Compared with natural stone and ceramic plates of the same area, the weight is more than 2~3 times, which affects The bearing problem of stone decoration in high-rise buildings is an important reason why natural stone can't enter high-rise buildings for decoration for a long time. Moreover, the price of natural stone is much higher than that of ceramics; for consumers in developing countries, the popularity of residential decoration is not high. The production of thin-plate stone can produce more stone plates under the consumption of unit resources. Compared with the current domestic processing level, the cost can be reduced a lot, thus entering the ordinary home decoration market.
Moreover, today's world architectural decoration industry is developing towards luxury and high-grade, and the market application of natural stone jewelry will become more and more important and more extensive.
Therefore, starting from the defects of the stone itself: reducing the thickness of the natural stone plate, reducing the weight per unit area, lowering the unit price, adapting to the consumption level of the general public and expanding the application range of the stone, has become an important factor in the development of the stone industry. The thinning and ultra-thinning of the stone solves these two important problems, which makes the stone decoration material usher in a more bright spring.
