A granite platform is a platform made of granite. Formed from igneous rock, granite is a hard, crystalline stone. Initially composed of feldspar, quartz, and granite, it is interspersed with one or more black minerals, all arranged in a uniform pattern.
Granite is primarily composed of quartz, feldspar, and mica. Feldspar accounts for 40%-60%, and quartz for 20%-40%. Its color depends on the type and amount of these components. Granite is a fully crystalline rock. High-quality granite has fine and uniform grains, a dense structure, a high quartz content, and a bright feldspar sheen.
Granite has a high silica content, making it an acidic rock. Some granites contain trace amounts of radioactive elements, so these types of granite should be avoided for indoor use. Granite has a dense structure, a hard texture, and is resistant to acids, alkalis, and weathering, making it suitable for long-term outdoor use. Granite has the following characteristics:
1. Granite has a dense structure, high compressive strength, low water absorption, high surface hardness, good chemical stability, and strong durability, but poor fire resistance.
2. Granite has a granular structure with fine, medium, or coarse grains, or a porphyritic structure. Its grains are uniform and fine, with small gaps (porosity is generally 0.3% to 0.7%), low water absorption (usually 0.15% to 0.46%), and good frost resistance.
3. Granite is hard, with a Mohs hardness of around 6 and a density ranging from 2.63 g/cm³ to 2.75 The g/(cm³) range has a compressive strength of 100-300 MPa, with fine-grained granite reaching over 300 MPa. Its flexural strength is generally between 10 and 30 MPa.
Fourth, granite has a high yield rate, is amenable to various processing techniques, and has excellent slab splicing properties. Furthermore, granite is not easily weathered, making it suitable for outdoor decorative purposes.
Maintaining a marble platform (marble slab) requires determining the tolerances and maintenance requirements of the current marble platform, as well as determining whether the work surface contains pits. If a marble platform has small pits on its surface, it should be returned to the factory for processing. If the precision has only changed, repairs should be performed at the site of use. After long-term, frequent use, a marble platform will If the marble platform is too flat, the precision error will gradually increase, resulting in inaccurate precision. In this case, it requires repair.
Maintenance steps for marble platforms:
1. Check the marble platform’s precision and determine its current error.
2. Rough-grind the marble platform using abrasives and grinding tools to achieve the required levelness.
3. The second semi-fine grinding of the marble platform after the rough grinding is to remove deep scratches and achieve the required levelness.
4. Grind the working surface of the marble platform to achieve the required precision.
5. Test the marble platform’s precision after polishing, and again after a period of time.
