Application Of Quartz Sand In Quartz Plate

2020-06-20

Quartz plates have become an emerging countertop material in the world, and more and more quartz sheet products in Europe and America have entered the consumer family. The more mature quartz stone market in the world is Australia, the United States, Canada, the United Kingdom, France, Germany and other countries. Among them, Australia’s annual consumption of quartz stone accounts for 35% of the world, followed by the United States 22% and Canada 14%.

According to industry insiders, the market for quartz sheet products is similar to that of the stone market 20 years ago, and the artificial stone market was 10 years ago. It is predicted that quartz sheet products will increase at a rate of 500% per year in the next few years, with huge market space.

First, What Is A Quartz Plate?

Quartz plate, also known as artificial quartz stone, is a new type of stone synthesized by more than 80% quartz crystal plus resin and other trace elements. It is a large-size sheet that is pressed by a special machine under certain physical and chemical conditions.

Quartz sand is the aggregate of quartz plate. The high hardness and high temperature resistance of quartz sand make the quartz plate not scrape (Mohs hardness 7); the stain is not dyed (vacuum manufacturing, compact and non-porous); Temperature 300 °C); not used (30 polishing process without maintenance); non-toxic and non-radiative (NSF certified, free of heavy metals, can be in direct contact with food) performance.

Second, Quartz Sand For Quartz Plates

Quartz sand for quartz plates is very demanding. Quartz sand for quartz plates produced by quartz sand processing plants must meet the following requirements:

• 1. Quartz sand particles are round and non-edge. Quartz sand for quartz plates requires that the particles be preferably spherical. The more the particles are spherical, the smaller the specific surface area, the smaller the oil absorption value and the less resin used. The greater the resistance of the non-granular quartz sand during mixing and stirring.
• 2. Quartz sand is fine and fine. Quartz plates are divided into fine quartz sand powder and coarse quartz sand with quartz. The coarse particles are made of aggregate, which is equivalent to the stone and steel reinforcement of the concrete; Fine powder is a filling and reinforcing effect, similar to fine sand in concrete; it makes the board denser and denser to achieve antifouling effect.
• 3. Quartz sand whiteness is high. Quartz plate with coarse quartz sand requires the same color, with fine quartz sand powder required whiteness must be greater than 90 degrees. When the fineness of fine quartz sand powder is greater than 90, it will not black when mixed with the resin.
• 4. Quartz sand contains low iron. Quartz sand contains more iron, which will make the quartz plate produced motley and reduce the quality of the product.
• 5. Quartz sand is dry without impurities. Quartz plate quartz sand raw materials need to remove impurities in the manufacturing process, so that the moisture is below 0.5%, to ensure that the quartz plate finished product does not contain any pollution sources and radiation sources, and is environmentally friendly.
• 6 quartz sand has a high silicon content. Quartz sand is required to have a high silicon content (≥98%) as an aggregate in quartz sheets.

Third, Quartz Sand Production Quartz Plate

At this stage, quartz sand used as a plate material is generally obtained from high-quality vein quartz and quartzite ore, and refined quartz sand for plate is obtained by crushing, sieving, magnetic separation and the like. Taking wet dressing as an example, the production process of refined quartz sand is:

Quartz ore – crushing (magnetic separation) – beneficiation (manual, photoelectric selection) – fine crushing (magnetic separation) – water washing – dehydration – drying – screening (magnetic separation) – selection (manual, Photoelectric selection) (magnetic separation) – finished product

Quartz sand for sheet metal is strictly prohibited to use pickled sand. Acid-washed quartz sand tends to leave acid on the surface of quartz sand particles, causing micro-acid and photo-oxidation, and the plate is directly yellowed. The acid-washed quartz ore is easier to wash off the acid residue, and the efficiency is higher than that of the pickled quartz sand, but the disadvantage is that some of the acid pickling is not available, such as the water line yellow skin in the middle of the quartz block.

The raw materials for producing quartz plates are 5-100 mesh quartz sand, 320-2500 mesh quartz sand powder, unsaturated resin, colorant and coupling agent, ultraviolet absorber, decomposing agent, curing agent and the like.

Fourth, The Application Of Quartz Plate

Quartz plates are made of vacuum-like materials such as dense, non-porous composites that are ideal for use in complex environments. The quartz surface has excellent corrosion resistance to acid and alkali in the kitchen, and will not be scratched by the shovel, and will not penetrate the micro-liquid substance, and will not cause yellowing or discoloration, even after prolonged use, the surface It is also as bright as the new countertops, and it does not require maintenance and maintenance, making it popular in the furniture and mall decoration market.
