White hemp granite is characterized by high surface brightness, corrosion resistance, acid and alkali resistance, high hardness density, high iron content, and no radioactivity. It is equivalent to American white hemp. It is a kind of grayish white granite with gray spots distributed and uniform design and color. Baima is most famous in Shandong Province. In addition, there are Lingbao Baima and Suizhou Baima. There are big flowers, middle flowers and small flowers.
Firstly, the natural granite is sawed into plate, the surface of the plate is first ground, and then placed on the fixed frame; then the flame spraying is stopped for the surface of Shandong white hemp after the initial grinding, which is characterized by the use of acetylene, oxygen, spray gun, and the flame moves on the plate surface averagely; the moving speed is 120-250mm per second, and the interval between the spray gun mouth and the plate surface is 20-40mm, and they are inclined to each other Angle, the temperature of the flame is 800 ~ 1000 ℃, stop spraying water on the white hemp before the flame is sprayed.
That is to say, visual inspection of the exterior structure of stone. Generally speaking, the stone with average fine material structure has fine texture, which is the best product of stone; the stone with coarse-grained and unequal grain structure has poor appearance effect, uneven mechanical properties and slightly poor quality. In addition, due to the influence of geological process, some veinlets and microcracks are often produced in the natural stone, and the stone is most likely to crack along these parts, which should be carefully removed. As for the lack of edges and corners, which affect the beauty, we should pay special attention to them when choosing.
That is to measure the size and specification of stone. In order to avoid affecting the splicing or forming the pattern, pattern, line deformation after splicing, affecting the decoration effect. I.e. listen to the percussion sound of stone. Generally speaking, for stones with good quality, average density and no micro cracks, the knocking sound is loud and pleasant; on the contrary, if there are micro cracks or veinlets in the stone, or the contact between particles becomes loose due to weathering, the knocking sound is coarse and dumb.
