Guangzhou marble production and supply components, Shenzhen marble components, Shantou marble member

Marble components using high-quality "Jinan Green" stone grinding machined and hand-made. Black gloss, structural precision, even texture, good stability, high strength, high hardness, to maintain high-precision mechanical components marble in heavy duty and general temperature under: http: //www.btjcjxsb.com/jixiegoujian/65.html adoption quality "Jinan Green" stone machined and hand a small coefficient of performance, high mechanical precision, anti-rust, anti-magnetic ,, proportion: 2970-3070kg / m3 marble marble member Chak member, structural precision, even texture, good stability, strength Large, high hardness, heavy duty and general temperature in the bottom two, compressive strength: 2500-2600kg / cm3 3, elastic coefficient: 1.3-1.5 × 106kg / cm2 4, water absorption: <0.13% Chak, structural precision, texture uniformity, stability, high strength, high hardness, high accuracy can be maintained under heavy duty and general temperature, and has no rust, acid, wear resistance, not magnetized, the same type, such as / cm2 5, Shore Hardness: HS70 member advantages over a marble, high accuracy, good stability, not deformed. At room temperature to ensure measurement accuracy. 2, no rust, acid, no special maintenance, good wear resistance and long service life. 3, work surface scratches, bumps, does not affect the measurement accuracy. 4. Measurement competent sliding along, no tight feeling. 5, members of the anti-abrasion characteristics of marble, high temperature, and maintenance. Physical stability, meticulous organization, by the impact of the grain off the surface edges can not afford, do not affect the accuracy of its flat granite precision measuring plate. The long-term natural aging rock, uniform structure, small linear expansion coefficient, internal stress completely disappeared, constant evaluation and identification methods: choose the right level: According Size allowable deviation, flatness and angle of tolerance, as well as the appearance of quality , surface finish and other indicators, marble divided into superior products, first-class goods and qualified three grades; grading marble, differential mainly through instruments, measuring tools detection to identification. Visual inspection of the appearance of different levels of quality marble is different. Because marble is a natural formation, defects are inevitable. While processing equipment and gauging the merits of the cause of the plate is defective. Some sheet metal plate is not full (warp or sag), plate defects (cracks, blisters, stains, etc.), board member of different specifications (such as missing corners, plate errors) and so on. According to national standards, each grade marble are allowed certain defects, but not so obvious Bale superior product. Selection of colorful marble pattern tone, hue and diverse, without an identical pattern, which is rare marble charm. Basically the same hue, color small, beautiful patterns is a concrete manifestation of improved varieties, otherwise it will seriously affect the decorative effect.
