Focus on the ceramic tile Market: Microcrystalline stone has entered a new height of development

in China, the research and development of Microcrystalline stone began in the 1980s, and has been developed for more than 20 years. At this stage, the microcrystalline stone is getting better in terms of production technology, color design and sales promotion. Especially in 2011 and 2012, it entered the outbreak period, forming a tripartite confrontation with polished bricks and antique bricks

in the current building ceramics market, microcrystalline stone is mainly secondary fired. However, problems such as uneven production processes, excessive imitation of designs and colors, and empty innovative products are also gradually emerging in this blue ocean. Some forward-looking enterprises took the lead in developing primary fired microcrystalline, which not only made up for the lack of secondary combustion, but also responded to environmental protection policies. There are different opinions on the secondary firing and primary firing of microcrystalline, so what is the current development of microcrystalline? How does the upstream industry promote the development of Microcrystalline stone market? The following is to explore the development path of Microcrystalline stone evolution

my name is microcrystalline stone

in the industry, microcrystalline stone is called microcrystalline glass ceramic composite plate, which is a product that combines a layer of MM microcrystalline glass on the surface of ceramic glass fossils and is completely integrated after secondary sintering. Its structure is dense, the crystal is uniform, and the texture is clear; Hard, wear-resistant mechanical properties, excellent acid and alkali resistance; And it has the unique pollution resistance of non water absorption, frost resistance and low coefficient of thermal expansion. Microcrystalline stone combines the high strength of ceramic materials and the decorative beauty of microcrystalline glass, which is luxurious, elegant, three-dimensional, rich and varied in color, as well as the dual advantages of two materials, such as anti pollution and pressure resistance, never fading, and no radiation. It also has the advantages of high strength and light weight of building ceramic bricks

Microcrystalline stone was first born in the United States in the 1950s. In the 1970s, Japan introduced Microcrystalline stone as a product type to the market. Once launched, its gorgeous and noble crystallization texture attracted the favor of architectural designers. In China, the research and development of Microcrystalline stone did not officially begin until the 1980s, and went to the industrialization test in the 1990s. Since 2001 and 2002, microcrystalline stone has entered the experimental stage that Dasheng needs to change oil once every six months. In the second half of 2002, it entered the stage of trial marketing and promotion. From 2004 to 2007, it entered the stage of rapid development. Many new brands and new enterprises went online to invest in production. Since 2007, the production technology of Microcrystalline stone has entered a new stage of development, from two materials in the past to the combination of three materials now, from the original high-temperature firing of microcrystalline glass to the extensive application of inkjet printing technology in Microcrystalline stone products. At present, the microcrystalline stones on the market are mainly the 12th and 13th generations (according to a new series, the emergence of similar products is defined as the first generation)

breakthrough point: the combination of technological innovation and publicity

the sustainable development of Microcrystalline stone will eventually be reflected in the technological breakthrough. More and more ceramic enterprises are competing in the microcrystalline stone market, and the phenomenon of homogenization and low price competition is rampant. Some forward-looking enterprises took the lead in developing primary fired microcrystalline, seeking a breakthrough in production technology, hoping to have lower cost and more environmental protection in terms of energy consumption. However, because the raw material cost and technical control of primary combustion are only mastered by a few enterprises, microcrystalline stone products are still dominated by secondary combustion at present

the main technical barriers to the production of Microcrystalline stone lie in three aspects: microcrystalline frit, expansion coefficient matching between green body and frit, and firing process. The core technology lies in the research and development of frit, which determines the final quality of the product, because frit is the last process of the whole production process of Microcrystalline stone. It is the glass chemical raw material laid on the glazed and printed ceramic tile body. After high-temperature firing and ceramic tile fusion, the product has high gloss, permeability, low water absorption and rich and bright colors

with the development and transformation of Microcrystalline stone from secondary combustion to primary combustion, the improvement of frit technology is the key. The current one-time sintered microcrystalline frit breaks through the traditional process principle of increasing the initial melting temperature of the frit, and adopts a special microcrystalline glass formula to allow the frit to crystallize under certain temperature conditions. The final product is almost comparable to the traditional secondary fired products. According to incomplete statistics, in the second half of 2012, there were no more than 10 enterprises developing microcrystalline frits for one-time firing, but in 2013, there were about 15 enterprises. At the same time, according to insiders, with the maturity and expansion of the microcrystalline stone market, there will be a concentrated outbreak period next year, with 34% of the toilets leaking. In Foshan, there are nearly 10 enterprises engaged in the R & D and production of microcrystalline frits, including Yuantai system, Sino US trade war and the impact of raw materials on the paper industry. The layout of raw materials has become the core competitiveness of paper mills, such as glaze, Weibang microcrystalline and xingkaiyuan glaze

while pursuing market profits, ceramic enterprises pay more and more attention to environmental protection and energy conservation in the production process. When 180 d=7a, they are also trying to reduce costs. One-time firing Microcrystalline stone can meet the above needs, which is the reason why many enterprises choose to develop one-time firing microcrystalline frit. However, the cost of investment in the research and development of frit often discourages many enterprises. According to a research and development enterprise in the industry, the investment in the research and development of once fired frit, including equipment, raw materials, manpower and so on, has reached more than 20 million yuan

not only the R & D and production cost of frit is high, but also the investment in R & D cost of ceramic enterprises' one-time firing micro crystalline technology can not be underestimated. A glaze enterprise once calculated such an account: Based on the analysis of one-time firing of microcrystalline frits, the frit required for an 800 800 (mm) one-time firing of Microcrystalline stone body is 3.5 kg, and the frit required for one-time firing of Microcrystalline stone body per square meter is 5.5 kg. Based on a production line with a daily output of 10000 square meters and 30 days a month, 1650 tons of frit are required per month, calculated at the price of 7500 yuan per ton of frit, The monthly investment amount of frit is nearly 13million yuan
