Full-size marble slab order unit parameters

Marble platform based on the quality of the rock layers underground mineral composition containing olivine, pyroxene, plagioclase, biotite, very fortunate that detects out in marble, contain magnetite measure, which is not found in other marble, and Jinan Green marble stone after millions of years of natural aging, there is no wear of the ages that the stone itself structurally uniform texture, fine crystalline, hard, physical stability, higher accuracy can be machined HT-250 material accuracy hardness 2-3 times higher than cast iron (equivalent to HRC> 51), made by hand lapping, much of the vast user in the laboratory, precision tools, machinery and parts inspection, and the whole instrumentation industry in favor . Order Unit: Beijing University of Aeronautics and Astronautics Laboratory Order marble rectangular foot, Department of Chemical Engineering, Dalian University of Technology Order marble slab, Shandong Green Power Equipment Co., Ltd. Order marble square box. Marble slab physical properties: specific gravity: 2970-3070kg / m3 Compressive strength: 245-254kg / mm2 elastic grinding capacity: 1.27-1.47N / mm2 linear expansion coefficient: 4.6 × 10-6 / ℃ water absorption of 0.13% Shore hardness HS70 the above. Precision respectively 000,00,0,1 level. Take lapping finished 2000 * 2500mm, 00 级 marble platform, for example: the user during use feedback: Marble does not rust, the same type, wear resistance, precision wear a small point, perfect effect, marble material processed slotting, drilling, mechanical assembly member, marble slab to use.
