The marble composite board has both the performance characteristics of natural stone and the comparative advantage in practical performance, which also determines the sustainable development of its future market. The increasing use of more and more countries and regions in the international market has also verified the market development trend of marble composite panels.


 First, the characteristics of marble composite panels


 Marble composite panels, as the name implies, are made of marble and other materials that have been processed to have the original marble decorative properties. Specifically, it has the following characteristics:


 1. The breaking force of the marble composite board is 258N/cm, which is more than 3 times stronger than the original board.


 2, no pan-alkali yellowing: because the marble composite board floor tile and resin adhesive layer block the water and corrosive substances, eliminating the common problem of the pan-alkali yellowing after the marble and cement wet paste, the wall stone can be directly wet, thus It saves the cost of dry hanging, reduces the space occupied by dry hanging angle steel and pendants, and increases the use area.


 3, light weight: marble composite board is more than 2 times lighter than the original board. Villa building marble


 4. Convenient construction: The marble composite board can adopt the tile construction method instead of the marble construction method, so it is easy to construct and save construction costs. Natural marble production


 5, the bond strength is ideal: the test shows that the adhesion: 91 N / cm2, the specification of 600 * 600mm marble composite board will not peel off under the gravitational force of 33 tons or more. Granite manufacturer


 6, strong heat resistance: marble composite board is so hot, long time (120 hours) in the 100 ° C environment without peeling, discoloration and other abnormal reflections. Marble manufacturer


 7. The water absorption rate is very low: the back of the marble composite board is covered with completely porcelain tiles, so the water absorption rate (0.13%) is very low, within 0.2%, it will not be cracked.


 8, the surface is smooth: the marble composite board is much smoother than the original board surface. Decorative stone marble


 9. Low price: Because the thin marble board is glued to the thick tile, the price of the marble composite board is about 30% lower than the original board.


 10, various specifications: specifications of 600 * 600mm and above a variety of specifications marble composite board or other specifications products, can be organized according to customer requirements. Luxury stone manufacturer


 Second, the processing procedure of marble composite board


 First, choose the high-grade marble variety that is marketable, and buy the blank tile with the specification of 610*610mm (that is, the tile whose surface has not been polished).


 1. Saw the board: The marble block is processed into a 14mm thick, 610*610mm plate on a two-way cutter and then dried.


 2. Bonding: Place the blank tile flat and face up, and apply the prepared adhesive on the surface of the rough tile and the side of the marble board. The adhesive should be evenly and thinly coated. It must be applied and evenly free of holes, otherwise it will affect the strength of the board, and it will be easy to fracturing during grinding; thin is suitable for bonding needs, just right, thick will cause waste and increase the thickness of the board. The face coated with the binder is then placed face down on the binder-coated blank tile; then the top of the marble board and the front of the other blank tile are layered. Thin and uniform adhesive, then another blank tile coated with adhesive side is combined on the marble board, and then pressed on it (use a heavy object such as a box of 10 305*305mm sheets pressed on it) After more than 10 hours of consolidation, it becomes a composite wool board with a layer of marble in the middle of the roughing tile. Building stone manufacturer


 3. For the section: The composite board with marble in the middle of the rough tile is mounted on the horizontal pairing machine, and the two sides are the marble composite board with two sides of the blank tile and the other side of the marble. Domestic granite building


 4. Control thickness: Because the marble composite wool board is composed of marble, adhesive and rough tile, it is inevitable that the thickness will be different. Therefore, it is necessary to control the thickness. The marble side of the marble composite board is facing up, and the thickness is controlled by the thickness control machine to the same thickness. Marble wall


 5. Grinding and polishing: After controlling the thick marble composite wool marble, the ten-head continuous grinding and polishing will become a high-gloss marble composite wool board. Decorative granite


 6. Cutting and chamfering: The marble composite board after grinding and polishing is cut into a 600*600mm composite board by a cutting machine, and then the edges are chamfered, and the marble composite board is finished. The finished marble composite panel has a thickness of 13 mm and the marble thickness of the composite panel is only 2 to 3 mm. The marble composite board is packaged and packaged for sale.
