How many grades does quartz stone have?
Quartz stone can be divided into three grades: A, B, and C. Among them, the physical and mechanical properties of B and C grade quartz stones, such as stain resistance, acid and alkali resistance, and wear resistance, have not all met the standard requirements, so B and C grade quartz stones cannot be used for indoor decoration. Among the three levels, only Class A can be used for normal indoor decoration, with good wear resistance, scratch resistance, heat resistance, and strong resistance to penetration and acid and alkali, making it a relatively high-quality decorative material.
1γ Advantages of quartz stone countertops
1. Impermeable and corrosion-resistant
Quartzite is actually a kind of compact and non porous composite material, which has strong corrosion resistance and permeability resistance. Even if colored liquids such as soy sauce, red wine, and fruit juice are knocked over on the countertop, as long as they are not cleaned for a long time, they can be easily wiped clean, and the pigment will not penetrate into the interior of the quartz stone. This also brings benefits to the appearance of the quartz stone countertop, and the prolonged use will not affect its luster.
2. Wear and high temperature resistance
In addition, the hardness of quartz stone is still sufficient, so it is relatively less prone to scratches compared to other materials of countertops, and has better wear resistance. Meanwhile, quartz stone is also a highly heat-resistant stone material, with a melting point of over 1300 degrees Celsius and good flame retardancy, making it perfect for use as a kitchen countertop.
2γ Disadvantages of quartz stone countertops
1. High prices
The price of high-quality quartz stone countertops is relatively expensive, while the performance of inexpensive artificial quartz stones is far inferior to that of high-quality quartz stones. So for families with limited budgets, quartz may not be the best choice with the highest cost-effectiveness.
2. Seamless splicing
On the other hand, quartz stone is difficult to process, which leads to its relatively single style and color, and it is not easy to seamlessly splice two pieces of quartz stone together. After the splicing is completed, there is often a gap that may not be visible to the naked eye, but there may still be infiltration phenomenon in the later stages of use.
