Features marble platform marble platform is mainly characterized by accuracy and stability, easy maintenance. This is because: ① marble platform structure dense, smooth surface wear, small roughness value; ② marble marble platform by the long-term natural aging, internal stress completely disappeared, material stability, not deformed; ③ acid, alkali, corrosion , anti-magnetic; ④ not damp rust Jinan Green marble platform, use, easy to maintain; ⑤ linear expansion coefficient, little affected by temperature; ⑥ Face after impact or scratches, only produce pits, no convex pattern, glitches, no influence on the measurement accuracy. Flat Rock main drawback is, you can not put too much impact, beat, high humidity will be deformed marble components, moisture is 1%. Marble work surface platform may not have a serious impact sand holes look and performance, shrinkage, scratches, bumps, holes, cracks, slag rust and other defects. Sunken marble platform or non-working surface off angle to allow repair. Marble platform material: based on the quality of underground rock layers, the main mineral components of pyroxene, plagioclase, a small amount of olive, biotite, and trace magnetite. After millions of years of natural aging, with a sophisticated structure, while black gloss, uniform, stable good performance marble platform base, while marble slab strength, hardness and high marble platform, under heavy load can still maintain high accuracy, even if by heavy bump, up out of fresh ballast only. Marble slab in addition to the above features, but also has "three" features - anti-magnetic, anti-corrosion, anti-deformation. Marble slab | marble platform of physical properties: a hardness of 2-3 times higher than that of cast iron equivalent HRC> 51, Mohs hardness of 6-7; the same compressive strength of 2290-3750 kg / cm.
