Fire surface is a kind of stone processing technology. Fire surface stone is widely used in subways, airports, squares, external wall hangings, sidewalks, parks, parking lots and other places. Today, let’s take a look with the editor of FABULOUS Group. Processing method of stone fire surface.

　　The stone fire surface is made by flame processing the stone and the surface layer is peeled off, and it will not change the quality and color at high temperature, and it can form a very beautiful pear-like surface. Since only the surface of the stone is heated, it will not have an adverse effect on the overall stone, and will not cause thermal deformation, cracks, embrittlement, etc. Fire-sintered rough surface technology can only be used for granite stone, while marble, sandstone, and slate can not be singed because of the chemical composition of the stone. The roughness of the burned surface cannot be controlled artificially, but is determined by the texture of the stone itself. The burned surface of the coarse-grained rock must be rough and the fine-grained rock is relatively delicate, so it has a certain naturalness!

　　The specific operation method of the stone fire board process is to use flame spraying to move evenly on the board surface at a moving speed of 120 to 250 mm per second. The distance between the nozzle and the board surface is 20 to 40 mm, and they are inclined to each other. The temperature of the flame is 800-1000℃, and the board is sprayed with water before the flame is sprayed (to prevent the board from being burnt when the flame is sprayed, and the water is heated to evaporate and absorb heat). Make it fall off the surface layer of 0.5 to 1 mm. The granite material processed by this method exposes the natural color of the stone, and is simple, rough and natural. Then use the stone anti-fouling and anti-seepage treatment method to maintain and protect the stone.
