Types of Marble
Types of Marble
The marble stone is the metamorphic rock formed by the high temperature and high pressure in the crust.The internal forces of the earth's crust promote the qualitative changes of all kinds of original rocks, that is, the structure, structure and mineral composition of the original rocks have changed.New rocks formed through qualitative changes are called metamorphic rocks.
Marble stone is mainly composed of calcite, limestone, serpentine and dolomite.Its main component is calcium carbonate, accounting for more than 50%.Because marble contains impurity commonly, and the action that caco3 gets carbon dioxide, carbide, water vapor in atmosphere, easy also decency and dissolve corrode, and make the surface loses burnish very quickly.Marble is soft in nature, which is relative to granite.
Marble stone overall grinding, polishing, crystallization processing technology marble international collectively known as marble, with its natural and simple texture, bright and beautiful color, is widely used in the building interior wall, because the marble stone is relatively loose, the texture of soft water absorption rate is relatively high.Joint line is more, so in the process of processing, transportation installation and use of easy to appear in a variety of pollution and warping deformation, easy to lose light and other phenomena, affecting the decorative effect, so the nursing of marble is a required course in the nursing industry.To make a comparative analysis of marble finishes, the nursing methods can be divided into:
The purpose is to make the stone as little as possible to absorb water, so as to reduce the water absorption law of stone. After 300#, we will do waterproof. At that time, the effect of waterproof will be reduced or disappear because of grinding.
Encounter relatively loose stone material, for example white sand cream-coloured, sandstone, tropical rain forest, wood grain stone to wait to want to use high content to seal firming agent first (if super hard inorganic coating, 40% of content above organic silicon resin sealant) make before processing, make to stone material in filling loose also hardened material at the same time.
The composition and structural characteristics of marble give it the following properties:
(1) excellent decorative performance, marble does not contain radiation and bright color, rich color, is widely used for indoor wall, ground decoration.
(2) excellent processing performance: saw, cutting, polishing, drilling, carving, etc.
(3) marble wear resistance is good, not easy to aging, its service life is generally in about 50-80 years.
(4) in industry, marble is widely used.Such as: used for raw materials, purification, metallurgical solvent, etc.
(5) marble has the characteristics of non-conductive, non-magnetic, stable field position.
