, any piece of stone on each building, must have a certain degree of mechanical xiamen tile and slab co.,ltd, such as compressive strength, flexural strength and the size of the mineral composition, structure, composition, structure, water saturation and so on, as compressive strength, quartz, feldspar is higher than calcite, dolomite, granite, in general it is higher than the compressive strength of marble. Granite, marble itself but also because of the different components have different mechanical strength, granite is generally higher than gabbro rock with different structures, different compression strength, such as fine-grained structure is higher than the coarse China stone suppliers structures, such as grain higher than the range Reap. Chinese granite acid properties and chemical composition very close relationship, in general, high Si02 content, acid resistance, while CaO, MgO content is high alkali resistance.
3, Processing:
granite suppliers mining, sawing, grinding, polishing, is itself against external mechanical force process. Low mineral hardness, single component, structure of uniform and easy processing. There Zhan, can only accommodate a certain intensity of rock, such as diamond frame saws suitable for cutting marble, ZBQ sand granite tombstone Sawing compressive powerful effect on the poor. Different mineral composition also affect the level of gloss on the dark polished mineral easy, light difficult. Ease of polishing and chemical composition is also relevant, such as the original ministerial TC79-92 natural marble building board standards for different components of the marble, its specular gloss have different requirements. Thus, according to the mineral composition, chemical composition can also be generally know whether the product gloss has reached its processing requirements. Different chemical composition also select different grinding article.
