Marble is formed by sedimentary rock and metamorphic rock of sedimentary rock, the main component is calcium carbonate, its content is about 50%-75%, showing weak alkalinity.Some marbles contain a certain amount of silica, while others do not.Fine particles (refers to calcium carbonate), the surface fringe distribution is generally more irregular, lower hardness.
(1) good decorative performance, marble does not contain radiation and bright color, rich color, is widely used for indoor wall, ground decoration.With excellent processing performance: sawing, cutting, polishing, drilling, carving, etc.
(2) marble wear resistance is good, not easy to aging, its service life is generally in about 50-80 years.
(3) in industry, marble is widely used.Such as: used for raw materials, cleaning agent, etc.
(4) marble has the characteristics of non-conductive, non-magnetic, stable field position.
From A commercial point of view, all naturally formed limestone rocks that can be polished are called marbles. Not all marbles are suitable for all architectural applications, so marble should be classified into four categories: A, B, C, and D.This classification method is especially applicable to the relatively brittle category C and D marbles, which require special treatment before or during installation.
Class A: high quality marble, with the same, excellent processing quality, free of impurities and pores.
Class B: the characteristics are similar to those of the former class marble, but the processing quality is slightly worse than the former;A natural defect;Small amounts of separation, gluing and filling are required.
Category C: there are some differences in processing quality;Defects, pores and texture fracture are common.Fixing these differences is moderately difficult and can be achieved by separating, gluing, filling, or reinforcing one or more of these methods.
Class D: its features are similar to those of class C marble, but it contains more natural defects and has the largest difference in processing quality, requiring multiple surface treatments by the same method.This kind of marble complicates many colorful stones, which have good decorative value.
