Hotel Decoration Stone
High-grade marble is commonly used in hotel decoration to the hotel one of the stone. Marble What are the features and benefits of it?
We first understand the origin of the Marble: Marble is a metamorphic rock formed crust original rock crust high temperature and pressure. Marble, calcite, limestone, serpentine, and dolomite constitute its main component, accounting for about 50% calcium carbonate, and other magnesium carbonate, calcium oxide, manganese oxide and silica, and the like.
Marble stone characteristics and advantages:
1, no deformation, high hardness, wear resistance.
2, anti-abrasion, high temperature, maintenance-free.
Stable, physics, careful organization, the impact of grain off the surface edges can not afford, do not affect the plane precision, stable material, to ensure long-term deformation, linear expansion coefficient, high mechanical precision, anti-rust, anti-magnetic, insulation .
Marble concrete can be subdivided into four main categories:
Class A marble: high-grade marble, has the same, excellent processing quality, free of impurities and porosity.
Class B Marble: characteristics close to the former type of marble, but the processing quality slightly worse than the former; natural defects, the need for separation of a small amount of adhesive and filling.
Class C Marble: processing quality, there are some differences, flaws, pores, texture fracture is more common. Medium difficulty patch these differences by separating one or more of the adhesive, filling, or the reinforcement of these methods can be realized.
Class D marble: Features and Class C similar to marble, but it contains a natural defect that more differences in processing quality, the same way many times the surface treatment.
Some marble also named after the place of origin, color, pattern and divided
