The difference between artificial stone and natural stoneFrom the point of view of environmental protection and durability of these two kinds of decoration materials what is the difference?
Because of natural stone surface pores, the area is relatively weak in general. The processing plant will be processed on the surface. In interior decoration, TV table, window table, indoor surface, suitable for the use of marble. And the threshold, kitchen table, ground suitable for outdoor use granite. The kitchen table is the best use of dark granite.Now on the market of natural stone, some color is the result of manual handling, and general use of these stones to half a year or so will reveal its true face. The most obvious market is now the largest green flowers, many of which are dyeing, is not really a big flower green.Also pay attention to the back of the grid, this situation has two kinds: 1 stone itself more brittle, must add the grid, such as Spain cream colored.2. cut corners, the thickness of these stones were thin, the strength is not enough, so I added a grid, generally darker stone if the grid, most of this factor.
Natural stone in daily use is mainly divided into two types: marble and granite. In general, where there is texture, marble, to spot the main known granite. It is in the broad sense. In a narrow sense, marble refers to the Yunnan from Dali stone. The truth now, the country is not a few pieces of stone out of Dali.The two can be distinguished from the geological concepts. The granite is igneous rock, also called acid crystallization plutonic rocks, is one of the most widely distributed rock in igneous rock composed of feldspar, quartz and mica, the composition of silica, about 65% ~ 75%, dense rock hard igneous rock is lava condensation crystallization. Underground magma or volcano eruption called and rock. The nature and content of feldspar igneous rocks in the silica content, determine the nature of stone. When the silica content of more than 65% belong to acid rock, the rock of orthoclase, plagioclase, quartz and other basic formation of mineral crystal, granular structure known as granite.
Marble is the original rock in the earth's crust formed through the crust in high temperature and high pressure metamorphic process. The internal forces of crust to the original rock types of qualitative change. A qualitative change refers to the structure, structure and mineral composition of the original rock changes. After the new type of rock formation change called metamorphic marble. By calcite, limestone, serpentine and dolomite. The main ingredient in calcium carbonate, accounting for more than 50%. There are other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. 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 but, the surface soon lose luster, relatively soft marble of a general nature, which is relative to the granite character. Of course, you don't need to ignore this, because The geological age is calculated by 100 million in the US, the rest of life, this qualitative change is a change.Of course, the above mentioned marble and granite in the above classification, is a more narrowly defined. Now the market has said, there are textures are metamorphic rocks, so also known as marble. The significant point spot crystalline particles, also known as a granite. In fact, classification too detailed, which is what a geologist, for interior decoration is almost on the line. Of course, if your stone used outdoors, because the environment is very bad, the need for a more detailed classification.
