The physical properties of marble platform: 1. proportion: 2970-3079kgm3 2. Compressive strength: 245-254N / mm2 3. elastic grinding capacity: 1.27-1.47N / mm2 4. linear expansion coefficient: 4.61 * 10 / kWh 5. Water absorption : less than 0.13% 6. Shore: Hs70 above "Precision Engineering" marble platform, the advanced countries accuracy reference standard flatness tolerance according to:. JB / T7975-1999 standard: 000 = 1 * (1 + d / 1000 ) um 00 级 = 2 * (1 + d / 1000) um 0 级 = 4 * (1 + d / 1000) um 级 1 = 8 * (1 + d / 1000) um (d diagonal mm) ( measuring the temperature is generally 20 + -2 degrees) Our product is good quality and low prices, excellent service to win customers' trust and praise. Welcome new and old customers to discuss cooperation, your satisfaction is our pursuit marble platform characteristic features marble platform mainly 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 marble slab production, internal stress completely disappeared, custom marble slab material stability, not deformed; ③ acid , alkali, corrosion resistance, anti-magnetic; ④ not damp rust, use, easy to maintain; ⑤ linear expansion coefficient is small marble components, little affected by temperature; ⑥ Face after impact or scratches, pits only produce does not produce embossed, glitches, no influence on the measurement accuracy. Flat Rock main drawback is marble slab, not to put too much impact, beat, high humidity will be deformed, 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.
