The stone processing industry has belonged to more traditional and simple mechanical processing enterprises for many years. The principle of mechanical equipment is simple, the precision of equipment is not high, and the process flow is not much. It is a labor-intensive enterprise. However, with the development of the economy, the emergence of the stone industry and the intensification of competition, equipment, support and market demand and product innovation continue to emerge, and some of them have opened up a new market area, that is, a stone composite board. First, the status quo of stone composite board market 1. Stone composite board marble is gradually favored by the decoration industry and customers due to its natural materials and changing colors and textures. There are about a thousand marble manufacturers in the country. Occupying a small part of the stone market, it is very competitive. In this environment, where manufacturers are forced to reduce costs by doing everything, in addition to working hard from management, the mechanical equipment and processing technology are similar, so a new technology and new products in a disguised thinking are born. This is the stone composite board. Save money from resources, from Im2 to 3m2 or even 4m2. Combined with other materials, it not only improves the performance characteristics of marble, but also retains the natural color and material of marble. This is the unique feature of marble's new product, a marble composite board. (1) Excellent performance of marble composite board Light weight: The thinnest marble composite board can be only 5mm thick (composite with aluminum-plastic composite board). Commonly used composite tiles or granite are only about 12mm thick, which saves a lot of cost in transportation and is the best choice for the building with load restrictions. Increased strength: When the composite of marble and ceramic tile, granite, aluminum honeycomb panel, etc., its bending, flexural and shear resistance are obviously improved, which greatly reduces the damage rate during transportation, installation and use. Increased anti-pollution ability: ordinary marble original board (through-body board) during the installation process or in the future use process, such as wet stickers with cement, it is very likely that after six months or one year, various discoloration and stains appear on the marble surface, which is very difficult Remove. The composite plate avoids this because the bottom plate is harder and denser, and there is also a thin layer of glue. It is easier to control the chromatic aberration: the marble composite board is cut into 3 pieces or 4 pieces into 3m2 or 4m2 with a 1m2 original board (one body board). The pattern of 3-4 m2 is almost 100% identical to the color, so it is easier to ensure the consistency of color and pattern when used in large areas. Easy to install: Due to the above characteristics, in the installation process, regardless of weight, easy to break (strength, etc.) or color separation, the installation efficiency and safety are greatly improved, and the installation cost is also reduced. Break through the installation restricted area: the decorative part of marble, no matter the inner and outer walls, the ground, the window sill, the porch, the table top, etc., the ordinary original board (the whole body board) has no problem, only the ceiling is marble or granite, any decoration The company does not dare or risk this risk. The composite board made of marble and aluminum-plastic board and aluminum honeycomb broke through the forbidden area of ​​this stone decoration. Because it is very light, it weighs only 1/5 - 1/10 of the body board. To decorate the ceiling with stone is none other than it. Sound insulation and moisture proof: The composite panel made of aluminum honeycomb panel and marble has the properties of sound insulation, moisture proof, heat insulation and cold resistance because of its hollow hexagonal honeycomb core made of equilateral hexagonal type. Therefore, these characteristics far exceed the performance characteristics that the whole body board does not have. Energy-saving and consumption-reducing: Because of its sound insulation, moisture-proof and heat-insulating properties, stone aluminum honeycomb composite panels can greatly reduce the consumption of electric energy and heat energy after installation indoors and outdoors. Reduce the cost: Because the stone composite material is thinner and lighter, it saves a part of the cost in transportation and installation, and for the more expensive stone varieties, the composite board is made to have different cost than the original board. (2) Production process of composite board The production process of ordinary marble original board (through body board) is relatively simple. For example, taking the processing from the block material as an example, the process is: block material _ sawing big cut → patching glue → automatic polishing → Trimming (finished product). The production process of the composite board is much more complicated, such as the processing from the block material as an example: block material → sawing big cut (disc saw big cut) → patching → trimming (initial finished product) → fixed thick bucket drying → sticky board → Slitting → Thickness → Drying → Sticking board → Slitting → Thickening → Brushing glue → Drying → Hand grinding (automatic grinding) → trimming → chamfering → drying → repairing → finished product (packaging). If the bottom plate purchased is not standard enough, the bottom plate should be reworked, usually trimming _ fixed thickness and drying. Therefore, the stone composite board is a labor-intensive product, which is in line with the export policy advocated by the state. If you don't take the bulk of the materials, you can buy them directly from the big board factory. In the early stage, the cutting process of the block material was omitted, but a process (cutting at the big board factory) was added to the surface process (the smooth surface was made into a matte surface). In this process, there are many technical and quality requirements that are almost completely different from the production process of large plates, and the standard requirements are higher, otherwise it is difficult to produce qualified products. . (3) Use of composite board Marble composite board has different performance characteristics due to its different composite bottom plates. Composite panels produced by different base plates should be used according to different use requirements and parts of use. The range of the composite board produced by the marble, ceramic tile, granite, calcium silicate board of the bottom plate: the marble composite board which is composited with these kinds of bottom plates is almost the same as the use range of the whole body board. If the building has special load-bearing restrictions, these composite panels are more useful, not only light weight, but also a lot of strength. The composite board produced by the aluminum-plastic panel for the bottom plate is used for wall and ceiling decoration due to its ultra-thin and ultra-light performance. Moreover, it should be glued with glue during the construction process, and other stones are irreplaceable when decorating the ceiling. The use of composite panels produced by aluminum front plate for bottom plate: The special properties of aluminum honeycomb panels make it more suitable for dry hanging applications of exterior walls and interior walls, generally used in large and high-grade buildings, such as airports. Exhibition hall, five-star hotel, etc. At the same time, it can also be made into countertops, dining tables and kitchen cabinets, and can also be made into solitary and cylindrical composite panels. Its excellent performance is favored in the selection of many dry wall materials. The use of composite panels produced by plastic honeycomb panels for the bottom plate: due to its weak flexural strength and high compressive strength, and because of its ultra-light performance, it is generally used for wall decoration, and can be installed by dry hanging. It can also be glued with special glue, which is more suitable for use on interior walls, ships and yachts. The use range of the composite board produced by the glass for the bottom plate: the performance of the marble natural material, because some of them have very good light transmittance, and the combination of these marble and glass can achieve the light-transparent decorative effect, generally using dry hanging and inlaying. The way to install, you can also install colored lights of different colors, coupled with music, will produce a fantastic effect. The future can also be used on the coffee table and tabletop of the furniture. At the same time, it can be equipped with some luminous materials, and it can still emit brilliant night light when the light is turned off. The use of composite panels produced by composite wood panels for floorboards: There are many varieties of composite wood panels. Different wood panels are used as the bottom panels, and the performance of the products is also different. It can be used for wall decoration and various furniture. (3) Unit price analysis of composite board The cost structure of the composite board is much more complicated than that of the whole body board. Because of its lm2 composite into 3m2, it can save more cost on the panel material, but the processing cost of the whole body plate is higher in the floor material, glue and other processing steps, so the unit price of the marble panel will be The key factor in the cost of composite panels. Under normal circumstances, the floor plate is the higher the price of the ceramic tile, granite, marble, and the higher the price of the composite board. The unit price of the marble board is about 200-300 yuan/m2, and the unit price of the composite board is almost equal to that of the large board, but it is still cheaper than the unit price of the specification board. The unit price of the marble slab is less than 200 yuan / m2, the unit price of the composite board is slightly higher than the original unit price, because the cost of the composite board is basically fixed regardless of the unit price of the marble slab, so the above will occur. This unit price changes greatly. It is not that the different types of marble composite panels are fixed at a lower percentage of the unit price than their whole body panels. If the bottom plate is made of high-grade materials, such as aluminum-plastic panels, aluminum honeycomb panels, glass, glass fiber mesh (cloth), carbon-coated panels and other materials. One is because of the higher unit price of the material; the other is because the processing technology is different from the processing technology of the ceramic tile and granite for the bottom plate, and the technical requirements are higher. Therefore, the unit price of such composite boards is almost higher than the unit price of the whole body board. (5) The target market for composite panels The technology of marble composite panels was born in Spain. The earliest technology development in China was in 1997. With the further maturity of technical equipment, the market is gradually sprouting. The sales market for composite panels is currently concentrated in the international market. Foreign countries have higher recognition and recognition of marble composite panels than domestic ones, so the current use of foreign countries is far greater than domestic. Mainly concentrated in several countries in Western Europe, such as Spain, Italy, Germany, and the United States, Australia, Japan, South Korea and so on. Due to the different levels of economic development, decorative styles, construction standards, etc., the types of composite panels used are not the same. Several countries in Western Europe like to use marble and marble composite; in the United States and Japan, aluminum-plastic composite panels and aluminum honeycomb composite panels are used; while in South Korea, composite panels of granite, ceramic tiles and marble are used. South Korea has the largest number of composite panels in these countries. There are very few inland manufacturers in China. The promotion is not enough, so many decoration designers or investors do not understand or even have heard of such products, so the recognition is very low, let alone the degree of recognition, so the current domestic sales are very small . (6) The status quo of the national composite board manufacturers Since the advent of the marble composite board, it has been six or seven years. Because there is still a technology and process exploration in the early stage, the process of improvement and improvement is summarized. Although it has been six or seven years, it has been blocked by the technology of such manufacturers. Therefore, so far, the manufacturers of marble composite panels are far lower than the number of other stone manufacturers, the number is very small. The number of marble composite board manufacturers in China is estimated to be about 100, and the total installed capacity of the main machine (slipping machine) is about 800 units. The theoretical annual output is about 5 million m2. The actual annual output in 2005 is estimated to be about 2 million m2. The area is divided into 15 in Hubei, 3 in Beijing, 4 in Shanghai, 5 in Shandong, and 20 in Guangdong. After two years of rapid development in Fujian, it has reached 40. Product Features: Although many manufacturers produce marble composite panels, the varieties are particularly single. For example, Hubei can only produce marble and marble composite panels, and the panel varieties are also very simple, mainly based on Shaanna beige; while many other manufacturers only produce fewer composite types. This is mainly limited by regions, processes and technologies, and there are only a handful of manufacturers that can produce various types of composite boards. Fujian manufacturers: Fujian Nan'an area is China's stone town, and it is very influential in China, Southeast Asia and even the whole world. The stone varieties of the whole country and the whole world have a large stock of raw materials, semi-finished products or finished products in the water head, so they choose a wide range and are more suitable for the establishment of composite board manufacturers. Fujian composite board manufacturers only had 5 or 6 before 2004, mainly concentrated in Fuzhou and Xiamen. As of October 2006, there are estimated 40 or so manufacturers in Shuitou Town, and the mainframe loading is generally more than 10 units. The total installed capacity of the main engine in Shuitou Town is estimated to be about 600 units so far. The monthly output is around 400,000 m2. 2. Prospects of the stone composite board market (1) Improvement and development of marble composite board equipment and processes There are two basic types of marble composite board main machine, namely, the cutting machine (also called sawing machine): vertical cutting and horizontal cutting . The basic principles are the same, all evolved from woodworking machinery. The form of slitting is woodworking band sawing, inserting head or electroplated diamond. At present, this kind of machinery is basically mature, and the process is basically semi-manual and semi-automatic. Semi-manual means that the process of bonding and separating, trimming and chamfering are separate and discontinuous; semi-automatic is a continuous production equipment. The thickness, the buffing, the trimming, and the chamfering are formed at one time. The two production methods have their own characteristics and their own strengths. Now the manufacturers are basically these two types. If the efficiency, quality, and yield requirements are increased, the existing equipment needs further improvement and a more reasonable improvement of the process. Nowadays, manufacturers have made efforts in this regard. If automatic equipment can be used in the sticking process, the efficiency will be greatly improved. In particular, aluminum honeycomb composite panels will have a large demand in the international and domestic markets in the next two years. The production process and quality requirements of aluminum honeycombs are higher, especially in terms of resistance to deformation and aging. Therefore, the quality requirements of the glue are higher, not only have a strong adhesive force, but also need to have a certain flexibility and elasticity. In this way, it can ensure that the stone and metal of two different materials with different degrees of expansion will not be disengaged under the large temperature change. Although the polyurethane glue has good toughness, the initial curing time is too long, which affects the production. Efficiency, at this point the glue manufacturer needs to make further improvements and improvements. In addition, in the production process of aluminum honeycomb composite panels, the current manufacturers have not achieved higher efficiency (due to the influence of the machine and equipment). If the composite board factory and the machinery factory, the automation equipment factory, the glue factory Cooperate, after a period of testing, the fully automatic assembly line will be available. (2) The increase and enrichment of stone composite materials In addition to the combination of marble and other materials introduced above, there are also some materials that can be combined with marble, such as composite wood, cement board, glass fiber, calcium silicate board, Silicon magnesium calcium plate, carbon plate, plastic plate, etc. These types of composite panels have yet to be further improved in production processes and technologies, and the market has yet to be cultivated and developed. In the future development of the type of composite board, there will be newer materials appearing, and the installation method may be completely different from the past. For example, the composite board is made into the floor style, and the installation method is the same as the wood board, and is directly plugged, It can be disassembled without cement wet, and this new composite panel will have more room for development in the future market. (3) The future market of marble composite panels The various types of marble composite panels introduced above are mature in technology and technology, some are still in perfect, and some are still being developed. These varieties are diverse, rich and varied in performance. They are laying a good product foundation for the future market. The preliminary technology of marble composite panels has gradually matured in the development of these years, and the quality of its products has also been fully guaranteed. In the overall market development in recent years, the international market has had a relatively preliminary development. Some projects in Western Europe, the United States, Austria, Japan, and South Korea have been used, and the overall response is relatively good. With the increase of manufacturers, the improvement of technology, process, product cost reduction, and market development efforts, the demand for composite boards in the international market will increase exponentially. Coupled with the continuous development of new products, the product performance will be further improved, and the range that can be used in the market will continue to expand. Although the domestic market is only in its infancy, it will soon enter the growth period after two or three years of cultivation. Market demand will gradually increase. Composite panels of different materials, different types and different uses will be increasingly decorated with various types of buildings. China's inland will be the largest potential market for composite panels in the future. (4) Granite composite panels are affected by mechanical equipment and processes. At present, granite composite panels can hardly be mass-produced. A small amount of materials are softer and smaller in size. However, there are only a few varieties that are far from meeting market demand. This kind of product has not yet been developed, and the market has already had more demanding desires, but only one of them has been restricted by various restrictions. From the perspective of future innovation of equipment, there is demand for power. For the market with strong demand, equipment manufacturers are also stepping up the speed of research and development in the near future, regardless of the principle of the equipment, the flexible energy of the band saw blade, or the cutter head and the process. Improvements are constantly improving and improving. I believe that this equipment and process will mature in the near future. From the perspective of the future market, the total sales volume of granite now accounts for the largest proportion in the stone. If the high-priced products such as American white linen and royal corn are combined with different materials, the original is changed. Some performance, increase its scope of use, and reduce its cost, then its future market prospects will be broader. Generally speaking, after several years of development, especially for the rapid development of Fujian Shuitou, the stone composite board has formed an industry group of stone industry, which has started its own brand in the international composite board market and has an important position. The status has exerted a great market influence, and this year's adjustment of the tax rebate for the stone industry, the zero tax rebate rate for ordinary stone products, in my opinion, the overall disadvantage of the stone industry in the near future, but the composite of deep processing The board industry is a very good news. With the adjustment of the tax rebate rate and the pressure of the renminbi, trading companies and foreign merchants will increasingly choose to implement and use composite boards. It is estimated that next year and the next year, stone composites The board industry will usher in a more beautiful spring!
