Advantages and disadvantages of natural marble
Shortcomings:A. because marble is generally contain impurities, and calcium carbonate by carbon dioxide, carbide, the role of water vapor in the atmosphere, but also easy to weathering and erosion, and make the surface soon lose luster. So a few of the more stable, durable such as white marble, Ai Yeqing, pure quality, less impurity species can be used outdoors, other varieties should not be used outdoors, generally used only for indoor decorative surface. The main varieties are: grey marble, marble color flower etc..B. radioactivity: natural marble radioactive, natural marble for qualified radioactive have strict control, will not cause harm to human body.
Advantage：A. natural marble texture compact but not large, easy to process, cut and polish, polishing, etc.. Marble polished after the smooth and delicate, natural and smooth texture, a high degree of decoration. Marble water absorption rate is small, high durability, you can use 40-100 years.B. natural marble has a fine texture, solid, polished, such as bright and clean mirror, texture than granite stretch, beautiful. High compressive strength (second only to granite), according to the different strata, up to 300MPa, small water absorption, abrasion resistance and other characteristics.
Natural marble is a metamorphic rock formed by high temperature and high pressure in the crust. It is a hard stone, mainly composed of calcite, limestone, serpentine and dolomite. The main components of calcium carbonate, accounting for more than 50%. Other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide.
Natural stone: natural marble, natural stone in high-grade granite is completely traditional raw materials used, the more commonly used are black and white two.Advantages: natural stone with natural texture, more beautiful, hard texture, abrasion resistance, scratch resistance performance is very prominent, its price is relatively low, is one of the most economical material.Disadvantages: 1, with high radioactivity, feel cold;2, hard enough, lack of flexibility, can not produce more than 1 meters of the table, easy to break when heated or hit, and it is difficult to repair, molding is not easy to smooth processing;3, there are natural pores, easy to be contaminated, easy to breed bacteria, easy to oil, easy to stain;4, by splicing operation artificial rubber and natural stone color to match, and the cross section is uneven, so it cannot achieve seamless, and natural stone are currently connected with domestic domestic adhesive glue, short service life, easy to mildew, formaldehyde content.
