Prirodni kamen je najraniji građevinski materijal u istoriji ljudske arhitekture, igra važnu ulogu u svakodnevnom životu. Proizvodi od prirodnog kamena se široko koriste u aerodromima, brzim željeznicama, vrhunskim hotelima i drugim velikim javnim zgradama, poslovnim poslovnim zgradama, stambenim zgradama, nadgrobnim spomenicima, itd. Sada u procesu uređenja doma kameni proizvodi dobivaju sve više pažnje, ali posljednjih godina cijena kamenih sirovina raste svake godine, i kupci terminala i proizvođači žale se na rastuće troškove.
Danas, s razvojem privrede, zelena gradnja, energetski štedljivi građevinski materijali su široko prihvaćeni od većine kupaca u svijetu. Hoće li umjetno kamenje u budućnosti utjecati na industriju prirodnog kamena? Ili je to samo dodatak prirodnom kamenju? Hoće li umjetni kamen zamijeniti prirodni kamen? Ovaj će vam članak pomoći da saznate odgovor.
Prirodni kamen se odnosi na sedimentne ili metamorfne karbonatne stene kao što su mermer, dolomit, krečnjak, pješčara, škriljaca i škriljevca. Moderni prirodni kamen se vadi iz prirodnog kamena, a zatim nakon niza obrade, što se tiče materijala koji se koristi u uređenju doma, generalni građevinski dekorativni prirodni kamen uglavnom granit i mramor dvije vrste.
Granit je magmatska stijena, koja se naziva i kisela kristalna plutonska stijena. To je najrasprostranjenija magmatska stijena, po sastavu feldspata, kvarca i liskuna, tvrda stijena. Granit se sastoji uglavnom od silicijum dioksida, oko 65%-75% takozvane magmatske stijene je podzemna magma ili vulkanska erupcija kristalizacije stijene lave.
Marble is a metamorphic rock formed by high temperature and pressure in the crust of the Central Plain. The internal force of the Earth’s crust causes the qualitative changes of the original rocks, i. e. the structure, structure and mineral composition of the original rocks are changed. New Rocks formed by metamorphism are called metamorphic rocks.
Umjetni kamen je izrađen od nezasićene poliesterske smole kao veziva, prirodnog mramora ili kalcita, dolomita, silikatnog pijeska, staklenog praha i drugih anorganskih materijala, kao i odgovarajuće količine usporivača plamena, boje i sl., nastaje miješanjem sastojaka , livenje keramike, vibraciona kompresija, ekstruzija i druge metode.
Iako je umjetni kamen sintetički, ali ima karakteristike običnog kamena. Na primjer, ima karakteristike otpornosti na vatru, otpornosti na habanje, otpornosti na udarce i nije radioaktivan. Ovo je također jedna od razlika između prirodnog i umjetnog kamena. Kao što je već spomenuto, umjetni kamen je nova vrsta materijala za uređenje doma. Ipak, njegova prodaja je izvanredna jer ima boju i teksturu prirodnog kamena. Ipak, cijena je niža od običnog prirodnog kamena, to je jedna od razlika između prirodnog i umjetnog kamena.
Prirodni kamen ima visoku čvrstoću, dobru otpornost na habanje, otpornost na koroziju, nisku apsorpciju vode i lijepu teksturu. Mramor se uglavnom koristi za uređenje interijera, a granit se uglavnom koristi za vanjsku dekoraciju, mramor zbog odlične otpornosti na visoke temperature, pogodan za kuhinjsku ploču.
Prirodni kamen ima pore, lako se nakuplja masnoća. Općenito, potrebna mu je jaka potpora kućišta zbog velike gustine;
Iako je tekstura tvrda, ali elastičnost je nedovoljna.
Osim toga, teško je popraviti ako postoje neke nevidljive prirodne pukotine.
Lako će puknuti kada se temperatura brzo promijeni.
Artificial stone has the advantages of bright color, high finish, uniform color, resistance to pressure and abrasion, good toughness, compact structure, strong and durable, light specific gravity, non-absorbent, erosion and weathering resistance, small color difference, non-fading, low radioactivity and so on. The stone material is easy to process into the mesa’s geometry, mesa, and so on.
The general naturalness of artificial stone is obviously insufficient, its texture is relatively false. Moreover, because the artificial stone manufacture craft difference is huge, the characteristic is not completely consistent. Due to the internal part of the resin material, if in direct contact with overheating containers, easy to heat deformation.
Natural Stone has radiation, carcinogenic rumors one after another, many consumers worry about the natural stone in the presence of radiation. Does natural stone really contain excessive radioactive material to endanger human health?
There is a mandatory standard for quantifying the radiation of building materials, which is classified into four categories: A, B, C and D, of which Class A is the building materials that can be safely used in any situation. All marble on the market is a class, only a few granite is a class B, class B must be installed in the ventilation used, class C and Class D has not yet been found in the market.
After millions of years of qualitative changes, the natural stone formed a different color and texture. Natural stone has a very high decorative texture and decorative grade. It has high ornamental value and always gives people beautiful feelings.
Artificial stone can be divided into organic artificial stone and inorganic artificial stone, the two differences lie in the use of different adhesives. In fact, after years of technological improvements, the entire industry now has the technology to ensure that both types of stone are healthy for the human body.
Natural Stone and artificial stone are two different fields, while they have a good complementarity, consumers could make a choic according to their actual needs, such as application areas, price range, environmental requirements to choose.
No matter natural stone or artificial stone, the price level relies on many factors: stone material supply, mining difficulty, processing cost, transportation distance, labor cost, marketing cost, etc., so it doesn’t mean the higher the price the better the quality. Usually, consumers make their choices based on their actual needs to choose some medium-priced products.
Natural Stone is a natural material, is transparent or translucent particles, very beautiful. So the natural stone feels brighter. Artificial stones are made from common natural stone powders or opaque acrylic materials, but they are also made by adding glue to the stone and pressing it. Its surface brightness is not as beautiful as that of quartz and can be said to be close to dull.
The other easiest way to tell a natural stone from an artificial stone is to touch it with your hand and then distinguish the two different stones by the feel of your hand. Natural stone material, the feeling that our hand touches above gives a person is the cold feeling. It’s like touching a natural stone. Artificial stones are different. Because the artificial stone material used inside the plastic material, so we do not touch the feeling of ice-cold, give the most obvious feeling is warm and delicate. This feeling is basically the same as when we touch other plastic materials.
Hardness is an important mark to distinguish natural stones and artificial stones. According to shore hardness, granite is defined as not less than 70(HSD ≥70) and marble is defined as less than 70(HSD < 70). Natural Stone is natural and relatively hard, so it is still not as flexible as artificial stone, while artificial stone is relatively soft so that it can do radian, splices are usually invisible at the seams.
There is a very simple method is to use hydrochloric acid test, a few drops of dilute hydrochloric acid on the stone surface, granite no obvious reaction, natural marble surface will appear rich foam, artificial marble foam weak, there is no bubble at all.
The permeability of natural stone is stronger than that of artificial stone. Drop colored liquid on the surface of natural stone, the color will penetrate into the stone, not easy to remove the traces left: and artificial stone permeability is worse, color penetration is slow if cleaned in time will not leave traces.
Today, natural stone mining is rampant, and it becomes scarce. Compared with natural stone, the characteristics of artificial stone also make it become the most important type of decorative material in landscape decoration today. They have many types and different uses, and the use method is very different according to their properties. No matter what kind of material, each has its own advantages and disadvantages. We should choose the material that suits us best according to our own needs and prices. Artificial stone has existed a long time in society and occupies a place in the stone market, it’s clearly impossible to replace the natural stone.
