Introduction to Raw Materials and Characteristics of Marble Marking Plates
Marble marking plates are sourced from underground rock strata. After hundreds of millions of years of natural aging, their structural characteristics are extremely stable, remaining unaffected by deformation caused by conventional temperature differences. The raw materials undergo strict screening in physical and chemical laboratories, featuring a dense crystal structure and solid texture. With a compressive strength of 2,290 - 3,750 kg/cm² and a Mohs hardness of 6 - 7, they exhibit excellent wear resistance, as well as superior acid - alkali and corrosion resistance, making them less prone to rust. Due to the use of non - metallic materials, they have no magnetic reaction or plastic deformation. Their hardness is 2 - 3 times higher than that of cast iron (equivalent to HRC hardness > 51), enabling long - term maintenance of accuracy grades. Even when struck by heavy objects, only a small amount of stone debris falls off, without deforming to damage accuracy like metal tools. As high - metrology standard parts, they outperform cast iron and steel materials, achieving high - precision and stable measurement benchmarks.
Core Advantages of Marble Marking Plates
These plates are manufactured from marble through mechanical processing and manual fine grinding, with a dark gray glossy surface and uniform texture. In addition to high strength and hardness, they have remarkable advantages such as non - rusting, acid - alkali resistance, non - magnetization, non - deformation, and good wear resistance. They can maintain stable performance under heavy loads at room temperature.
Classification and Applications of Marble Platforms
Marble marking plates, measuring platforms, inspection platforms, etc., all belong to the category of marble platforms, with different names due to varying usage scenarios. As high - standard measuring tools made from natural marble, they serve as ideal reference surfaces for instrument testing, auxiliary tool calibration, and precision verification of mechanical parts. Especially in the field of high - precision measurement, cast iron plates are difficult to match due to their own characteristics. Marble plates and platforms are widely applicable to industrial production testing and laboratory precision measurement scenarios. Their main mineral components are pyroxene and plagioclase, with small amounts of olivine, biotite, and micro magnetite. After hundreds of millions of years of aging, they have uniform and stable hardness, a solid structure, and can continuously maintain high precision under high - load conditions.
