Marble composite board definition, processing procedures and features

Marble composite board, as the name suggests, is a composite board of marble and other materials processed to have the original marble decorative properties. Specifically, it has the following features:
1. The twisting force of the marble composite plate is 258N/cm, which is more than 3 times stronger than the original plate.
2. Non-alkaline yellowing: As the marble composite floor tile and resin layer block the water and corrosive substances, eliminating the common problem of pan-base yellowing caused by marble and cement paste, the wall stone can be directly wetted, thus The cost of dry hanging is saved, and the space occupied by hanging angle steel and hanging parts is reduced, and the use area is increased.
3, light weight: Marble composite board lighter than the original board more than 2 times the weight.
4, to facilitate the construction: marble composite board can use tile construction methods, rather than marble construction methods, it is easy to construction, saving construction costs.
5, the ideal bond strength: Test shows that the adhesive force: 91 N/cm2, specifications for the 600*600mm marble composite panel under 33 tons of gravitational force will not have the phenomenon of peeling.
6, heat resistance: marble composite panels are hot, long time (120 hours) at 100 °C environment without peeling, discoloration and other abnormal reflection.
7. The water absorption rate is very low: the marble composite board has a completely porcelain tile on the back, so the water absorption rate (0.13%) is very low, and within 0.2%, it will not be cracked.
8, the surface smooth: marble composite board than the original surface smoothness is very good.
9. Low price: Due to the use of thin marble slabs glued to thick tiles, marble composite slabs are about 30% lower than the original slabs.
10, specifications and diverse: specifications for the 600 * 600mm and above a variety of specifications of marble composite board or other specifications, according to customer requirements for production.

Marble composite board processing program
First select the marketable high-grade marble varieties, and purchase rough tiles with a specification of 610*610mm (that is, the tiles that have not been polished on the surface). 1. Saw the wool board: The marble blocks are processed into a thickness of 14mm and a size of 610*610mm on a two-way cutting machine, and then dried.

2. Bonding: Put the rough tiles flat and face up, and paint the adhesive on the surface of the rough tile and the marble wool board. The adhesive should be evenly coated and thin, and evenly on the surface of the board. To be coated evenly can not leave holes, otherwise it will affect the strength of the plate, and it is easy to crush when grinding; thin is suitable for bonding needs, just right, thick will cause waste and increase the thickness of the plate. Then glue the coated side of the adhesive to face down onto the coated ceramic tile; then apply a coat on the top of the marble board and the front of the other tile at the same time. Thin and uniform adhesive, and then another piece of rough tile coated on the adhesive side is put on the marble wool board, and then pressed on it (the available weight is a box of 10 305*305mm thin plates pressed on it). After more than 10 hours of consolidation, it becomes a compound hair board with a layer of marble in between.
3. On the profile: The compound hair plate with marble in the middle of the blank tile is placed on the horizontal splitting machine. The split is a composite marble plate with two blank tiles on one side and marble on the other side.
4. Control thickness: Because the marble compound hair board is composed of marble, adhesives and blank tiles, it is inevitable that there are differences in thickness. Therefore, we must control the thickness. The marble of the marble composite board is faced up and controlled by the thick machine to reach the same thickness.
5. Grinding and Polishing: After controlling the thickness of the marble composite board marble and using ten continuous grinding and polishing upwards, it becomes a highly glossy marble composite board.
6. Cutting and chamfering: After grinding and polishing, the marble composite wool board is cut into a 600*600mm specification composite board by a cutting machine, and then chamfered to the edge to become a finished marble composite board. The finished marble composite board has a finished thickness of 13 mm, and the composite board has a marble thickness of only 2 to 3 mm. The marble composite board can be sold after being packaged and boxed.
