The difference between quartz stone countertops and artificial granite countertops
Quartz stone countertops are a new type of artificial stone made of small ornate stone. The manufacturing process is made by connecting a set of the most advanced and patented systems. The product contains more than 90% natural quartz stone or granite combined with an ultra-high performance resin and special pigments. The countertop made of quartz stone has no radioactive elements harmful to human body on the basis of high hardness, high temperature resistance, acid and alkali resistance, impact resistance and easy cleaning. Quartz stone plates usually contain up to 93% natural quartz. They also contain resins, mineral pigments and other additive components. The selected materials are densely packed under vacuum and vacuum to form an extremely compact composite, which is then subjected to complex slitting and The surface polishing process becomes quartz stone. The surface of this plate is as hard as granite, the color is as rich as marble, the structure is anti-corrosion and anti-fouling like glass, and the finished form is as perfect as artificial stone.
Its main material is quartz, quartz stone without radiation, high hardness, created quartz stone countertop scratching (Mohs hardness 7), pollution is not stained (vacuum manufacturing. Dense non-porous), hot is not bad (quartz material. Temperature resistance 1300 ° C), not used (30 polishing process without maintenance), non-toxic and non-radiative (NSF certification, no heavy metals, can be in direct contact with food). Quartz stone countertops are available in a variety of colors, Gobi series, crystal series, Ma Shi series, and flash star series. They can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc.) and home decoration (kitchen countertops, The fields of washstands, kitchen walls, dining tables, coffee tables, window sills, door covers, etc. are environmentally friendly, green new building interior materials that are free of radioactive pollution and reusable.
Artificial granite countertops.
The artificial granite is made of unsaturated polyester resin as a binder and bonded by marble powder sand or granite fragments with a binder. Ordinary granite, also known as artificial marble. There are two production methods: tablet production and block production, both of which have advantages and disadvantages. The former is superior in diagonality and flatness, while the latter is better in uniform color and can also be shaped, such as cylindrical processing. There are more production methods for the granite in the market.
Product characteristics: Most of the granites are made of organic pigments with different colors. The organic pigments are not resistant to sunlight, moisture, acid and alkali, and are easy to fade or even change color. 2 Gangshi has a high content of glue. On the one hand, the texture of the stone is not strong, and the decoration effect is not high. On the other hand, the glue has a large thermal expansion and contraction, the product is easy to deform and warp, and the service life is short. Moreover, the glue generally contains Volatile toxic gases are harmful to humans. 3 Gangshi due to process reasons, a lot of pores, product impact resistance is poor, and easy to seep and bleed, poor resistance to disease, its gloss is more fake, easy to wear, not lasting. 4 The granite used as raw material is not resistant to acid, because its main component is CaCO3, CaCO3 reacts with acid and decomposes; the hardness of marble powder and binder is very low, so the hardness of granite is also very low, generally less than Mohs hardness 3, so it is not wear-resistant, not resistant to scratching, easy to scratch. 5 The first generation of granite has more or less radioactivity due to the inclusion of marble and granite components.
The artificial granite is mainly used for interior walls and floors. The physical properties are lower than natural stone and quartz stone during use. When used on the ground, it is easy to cause drums, discoloration, scratches, etc. It is extremely difficult to clean after long-term use. In terms of surface gloss, it also has a big gap with natural stone.
