Aggregate stone/artificial stone
Artificial stone is made of unsaturated polyester resin as binder, natural marble or calcite, dolomite, silica sand, glass powder and other inorganic powders, as well as a proper amount of flame retardant and colorant. It is molded and solidified by mixing ingredients, porcelain casting, vibration compression and extrusion. Artificial stone is based on the problems existing in the actual use of natural stone, and has made great progress in moisture-proof, acid-proof, high temperature resistance, flat-fell seam and so on. Of course, man-made things naturally have man-made shortcomings. Artificial stones obviously lack a sense of nature and have a fake texture, so they are often used in places with high practical requirements such as cabinets and some places with harsh environments, such as kitchens and bathrooms. Window sills, floors and other places that emphasize decoration are used less.
Another factor that hinders the use of artificial stones is the human factor. Because the manufacturing process of artificial stone is very different, and the performance and characteristics are not exactly the same, the advantages mentioned above are not necessarily the performance of the artificial stone you bought. At present, the properties of artificial stones imported from the market are relatively good. For example, imported marble is allowed to polish the scratches on the surface with sandpaper, so it is no longer obvious for users to handle them themselves, but many domestic artificial stones obviously cannot support this kind of talent flow, and the more polished they are, the worse they get.
When buying artificial stone, it's best to take a sample and conduct a bad test, such as pouring soy sauce or oil stains, and conduct a destructive test. To sum up, what kind of stone to buy depends on the location, purpose and personal economic ability.
Simply put, there are three main differences:
First, natural marble has radiation, which is harmful to human body, while artificial marble does not have this problem.
Second, the permeability of natural marble is stronger than that of artificial marble. Permeability means that if colored liquid is dropped on the natural marble countertop, the color will penetrate into the countertop and cannot leave a permanent mark clearly; The artificial marble has poor permeability and slow color penetration. If it is cleaned in time, it will not leave traces.
Third, the price is different. Natural marble is more expensive.
In addition, in the choice of patterns and colors, man-made ones are more abundant, and homeowners can choose their favorite colors.
