Introduction of artificial quartz stone countertops and granite countertops
Artificial Quartz Stone Countertop
The main component of artificial quartz stone is silica, which is composed of 93% quartz sand as the filler and 7% resin and other binders. Less than 7% has insufficient toughness and is easy to break; higher than 12% is easy to deform. Quartz stone is generally 15 mm thick. The production process of different quartz stone manufacturers can be divided into cast quartz stone and die-cast quartz stone. Quartz stone has a rich variety of colors. In theory, any color can be formulated through various types of pigments.
Quartz stone has excellent scratch resistance and dirt resistance due to its high density and strong hardness. It is not scratched and corrosion resistant. However, from a physical point of view, quartz stone has fine thermal expansion and contraction properties, and has certain mechanical properties such as shrinkage stress, impact toughness, and elongation at break. When the material cannot withstand the internal stress caused by thermal expansion and contraction And cracking occurs when subjected to severe external impact.
The surface of the quartz stone plate is not treated in a special way, but is made by more than 30 high-pressure rapid water grinding. Once it is polished at a low speed, it will cause whitening and discoloration. The common problem in the installation joint of quartz stone is that the height of the two plates appears, and the treatment method is often to choose sanding, which will cause the surface of the plate to lose its luster. Therefore, the level of the installation master is tested in the seamless splicing process.
Qualified and high-quality quartz stone adopts die-casting process, the density can reach 2.46g/cm3, the water absorption rate is 0.02%, and it is better in terms of anti-seepage. However, some unqualified quartz stone products will infiltrate contaminating impurities during daily use and affect their appearance.
What is the difference between die-cast quartz stone and cast quartz stone?
Die-cast quartz stone is produced through a series of equipment such as high temperature, high pressure and high vibration. The die-casting plate is mixed with dry powder and the raw material ratio is different. It is formed by vacuum and high pressure, and the density and hardness are higher.
Casting quartz stone slab, in simple terms, the method is almost the same as ordinary artificial stone. The liquid is solidified on the mold and formed in a vacuum. The equipment cost is low. General artificial stone manufacturers can produce it. The density and hardness are not enough, and it is suitable for penetration.
How can we distinguish them quickly?
1. Look, the particles of the cast plate are larger, and the particle distribution is uneven, and the back side is obviously less than the front side. The particles of the die-cast plate are evenly distributed.
2. Use a hard object to scratch. The hardness of the cast plate is lower than 4, and the hardness of the die-cast plate is equal to or higher than the Mohs hardness level 6, so the die-cast plate will not be scratched.
3. Compared with the specific gravity, the internal structure of the die-cast plate is compact and stable, and the density is high. The internal structure of the cast plate is unstable, so the density is low. Therefore, the weight of the die-cast plate is much heavier than the cast plate!
Granite is the strongest kind of rock. It is dense, hard texture, acid and alkali resistant, and weather resistant. It can be used outdoors for a long time. It is not only hard in texture, but also not easily dissolved by water and not easily corroded by acid and alkali. In its area per square centimeter, it can withstand a pressure of more than 2,000 kilograms; in a few decades, weathering cannot have a significant impact on it.
Some granites are treated with dyeing and electrolysis in order to make the color more vivid and even or change the color. This type of granite is not suitable for kitchen countertops.
The thickness of granite countertops is usually 2-3 cm or 3/4-1 inch. 3cm granite countertops are more expensive, but stronger and more attractive. However, 2 cm of granite countertops usually need plywood support and edge trimming. If you don't like the standard style, you can ask the manufacturer to design and customize. When you use it with cabinets or other furniture, you need to edge the countertop. Due to the length of granite specifications, splicing is required. Therefore, gaps are very common, and gaps within the standard range are allowed.
