The difference between artificial marble and natural marble

Many families decorate the marble will be used, but marble with natural marble, artificial marble, artificial marble and marble so what is the difference? Do not worry, following a small series together to see the difference between artificial marble and natural marble in the right place.

First, the difference between artificial marble and natural marble

1, artificial marble

Artificial marble is made of natural marble or granite crushed stone for the filler, with cement, gypsum and unsaturated polyester resin as a binder, after molding, grinding and polishing made.

2, natural marble

Natural marble is the metamorphic rock formed by the original high-temperature and high-pressure rock in the crust. Belong to the hard stone, mainly composed of calcite, limestone, serpentine and dolomite. A few, such as white marble, Ai Ye Qing and other pure, less impurities and more stable and durable varieties can be used outdoors, other varieties should not be used outdoors, generally only for interior decoration. The main varieties are: cloud ash marble, Caihua marble, and so on.

Second, the introduction of natural marble

1, the general classification method

Natural marble in daily use is mainly divided into two types: marble and granite.

In general, any texture, called marble; to spot-based, known as granite. This is in a broad sense. In a narrow sense: marble refers to the marble produced in Dali, Yunnan. In fact, with the wide application of marble, it is scarcely produced exclusively from Dali.

2, to distinguish between the concept of geology

(1) Granite is igneous

These two can also be distinguished from the geological concept. Granite is igneous and also called acid crystalline deep pluton. It is the most widely distributed rock in igneous rock. It consists of feldspar, quartz and mica. Its composition mainly consists of silica, accounting for about 65% -75% Hard and dense quality. The so-called igneous rock is the underground magma or lava volcanic lava condensed rock crystallization. The content of silica in igneous rocks, the nature of the feldspar and its content determine the nature of the stone. When the content of silica is more than 65%, it belongs to acidic rock. In this kind of rock, the basic minerals such as orthoclase, plagioclase and quartz form granular structure and are called granite.

(2) Natural marble is a metamorphic rock

Natural marble is the metamorphic rock formed by the original high-temperature and high-pressure rock in the crust. The role of the crust of the internal forces to promote the original variety of rock qualitative change process. The qualitative change refers to the original rock structure, structure and mineral composition changes. After the qualitative change of the formation of the new type of rock known as metamorphic rocks. Marble consists mainly of calcite, limestone, serpentine and dolomite. The main component of calcium carbonate, accounting for more than 50%. There are other magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide.

Because marble generally contains impurities, and calcium carbonate in the atmosphere by the role of carbon dioxide, carbides, moisture also easily weathering and erosion, leaving the surface quickly lose its luster, the general nature of the marble is relatively soft, which is relative to the granite Stone terms. Of course, you do not have to deal with this because the age of geology is calculated on the basis of millions. This qualitative change is a limited change in our lifetime.

Of course, the above-mentioned marble and granite are more narrowly defined in the above classification. In general we have seen the texture of metamorphic rocks, it is also commonly known as marble. Spotted crystalline particles, also known as granite. In fact, too detailed classification, it is a matter geologist, for interior decoration, almost on the line. Of course, if your stone is used outdoors, the environment needs to be classified in more detail because of its harsh environment.

3, the application of natural marble in the home improvement

Because the surface of natural stone pores, so weaker in the dirt. Generally in the processing plant will be processed on its surface. In the interior decoration, the TV table, windowsill countertops, indoor floor, etc. suitable for the use of marble. The threshold, kitchen counter, outdoor ground is suitable for use granite. One of the best countertops kitchen is the use of dark granite.

The natural stone sold on the market, part of the color is artificially processed, these stones generally use about half a year or so will reveal its true face. The most obvious is the large green, many are made of dyed, not the real big green.

* Also note that the back of the grid, there are two kinds of situations:

(1) The stone itself is more brittle and must be gridded, such as Spanish beige.

(2) cut corners, the thickness of the stone is thinned, the strength is not enough, so add the grid, the general color darker stone if there is a grid, the majority of this factor.

Third, the introduction of artificial marble

1, according to the needs of a special artificial stone

Artificial marble is based on unsaturated polyester resin binder, together with Natural marble or calcite, dolomite, silica sand, glass powder and other inorganic powder, and the amount of flame retardant, color, etc., after mixing ingredients, casting, Vibration compression, extrusion and other methods of molding made of a solidified stone.

Artificial stone is artificial according to the actual use of the problem and developed it in the moisture, acid, alkali, high temperature, patchwork has made great strides. Of course, man-made things naturally have man-made shortcomings, artificial stone is generally less than the natural nature, it is used for cabinets and other places for more demanding practical requirements for the windowsill, the floor emphasize decorative less.

2, the production process differences impede the use of artificial stone

Another factor impeding the use of artificial stone is human factors. Because artificial stone production process varies greatly, so the performance characteristics are not exactly the same. So the performance mentioned above must be the performance of the artificial stone you purchased. Imports of artificial stone in the performance is better, relatively speaking, made in China may only "blow" of the copies. To put it simply, the imported marble allows sanding of scratches on the surface with sandpaper, which is no longer visible to the user himself, and many domestic artificial stones obviously can not support this practice.

Artificial marble suitable for use in some harsh environments, such as kitchens, toilets and so on. Because the texture is too fake, it is seldom used in decorative projects for decoration.

To buy artificial marble, it is best to first take a model for bad tests, such as pouring soy sauce or oil, and wear test.

In summary, what kind of purchase, according to different uses and personal economic ability. If the economic conditions are good, then use Natural marble. Above on the difference between Artificial marble and natural marble is simply introduced here, I hope for your help. More information, all in the network, so stay tuned.
