What is quartz stone?
In recent years, quartz stone has continually reshaped public perceptions, with engineered stone emerging as an irreversible trend—both now and in the future. It boasts exceptional appeal in terms of compatibility with architectural moduli, aesthetic versatility, and comprehensive practical value, while its perfectly balanced golden‑ratio dimensions have become the latest hallmark of home‑decor materials.
Quartz stone is a new type of engineered stone made by using 90% quartz sand powder as the primary aggregate and 8% resin, pigments, and other auxiliary materials as the main binding agents. After mixing, it undergoes vacuum‑assisted pressure vibration molding, curing, and subsequent processing steps. It is an eco-friendly, green, next-generation building and decorative material that is free of radioactive contamination and can be reused.

1. Resin: Resin is the fundamental material of quartz stone, serving to bond the components and impart toughness.
2. Filler: The main component of quartz stone filler is silicon dioxide, with other constituents including quartz sand, quartz powder, foundry sand, crushed glass, shells, feldspar, and more.
3. Pigments: The role of pigments in quartz stone is to formulate a variety of patterns and hues, resulting in a rich and vibrant color palette.
4. Curing agent: Curing agents are indispensable additives in the production of quartz stone, playing a crucial role in its shaping and dense consolidation.
5. Other additives: Resin is a polymeric material; the appropriate addition of certain additives can enhance its processing characteristics, boost production efficiency, improve the performance of quartz stone, and extend its service life.
Raw materials are conveyed via a fully automated pipeline system, and a closed‑loop mixing process that combines planetary revolution with spin is employed to ensure more thorough and uniform blending, thereby fully guaranteeing the homogeneity of the quartz stone slabs.
We have introduced a vacuum‑powered high‑pressure press, and through meticulous, repetitive pressing processes, we ensure the quartz stone’s exceptional density and hardness, laying a solid foundation for its scratch resistance, wear resistance, fracture resistance, and impact resistance.
The polishing system employs a new patented polishing machine, with each unit equipped with 34 grinding heads. This not only enhances polishing efficiency and reduces costs but also ensures that quartz stone products achieve exceptional high gloss, with a flawless surface free of scratches, smoothness, and superior resistance to stains and discoloration. In addition, a 12,500 m³ submerged‑water treatment tank guarantees the reuse of industrial water—such as polishing wastewater—without any discharge into the environment.
The product quality inspection area is equipped with numerous automated suction‑plate and flipping devices, which not only reduce labor costs and enable efficient quality checks but also ensure that inspections are conducted with greater care and rigor. Our principle is: no product that fails to meet our quality standards will ever leave the factory!
Quartz stone boasts superior hardness, rigidity, and weight compared to natural marble and standard engineered stone, offering excellent scratch resistance and wear durability.
1. Scratch-resistant: Quartz stone contains over 90% quartz sand and is compacted under high pressure, giving it a bulk hardness of at least 5 on the Mohs scale—harder than kitchen utensils such as knives and scrapers—so it is highly resistant to scratches.
2. Strong resistance to contamination: Quartz stone is a solid, dense, non-porous surface material manufactured under vacuum conditions, with uniform properties throughout. Its surface exhibits excellent resistance to acids and alkalis; any liquids left on the surface for an extended period can be easily removed by wiping with water or a cleaning agent such as Clorox.
3. Flame-resistant and fire-retardant: Natural quartz crystals are quintessential refractory materials. Quartz stone made from more than 90% natural quartz exhibits exceptional fire resistance and does not ignite upon exposure to high temperatures, offering superior heat‑resistance that artificial countertops simply cannot match.
4. Non-toxic and radiation-free: Quartz stone features a smooth, even surface that resists scratches and harbors no crevices; its dense, non-porous structure leaves no hiding place for bacteria. Zhongxun quartz stone is non‑toxic and radiation‑free, NSF‑certified, and safe for direct contact with food.
5. Anti-permeation and colorfastness Zhongxun quartz stone products are manufactured using vacuum casting, resulting in a dense, non-porous structure. After undergoing multiple polishing processes and incorporating high-quality composite agents and anti‑stain additives, the products exhibit low water absorption, excellent resistance to penetration, and superior stain resistance.
In addition, quartz stone can be used for bay windows, TV backdrop walls, bedside tables, desks, and more. Looking ahead, as quartz‑stone manufacturing techniques and protective treatments continue to mature, it will also find applications on floors and walls.
Quartz stone is a dense, solid surface material with exceptional hardness, composed of high-quality quartz sand and polymer resins, forming a seamless, pore‑free structure. It boasts superior properties such as chemical resistance, scratch resistance, and stain resistance, making it ideal for professional countertops. With comprehensive advantages that other materials struggle to match, quartz stone countertops offer unparalleled performance. To enhance their aesthetic appeal, keep kitchen surfaces clean, and maintain hygienic living conditions, regular daily care and maintenance are essential. Today, we’ll provide a systematic guide on how to properly care for quartz stone countertops.
As is well known, Zhongxun quartz stone is an eco‑friendly surface material that has earned authoritative NSF (National Sanitation Foundation) certification. The product is non‑radioactive and safe for direct food contact, making it widely used for kitchen cabinet countertops, office desks, and other applications. Consequently, it can inevitably become stained by grease, coffee, wine, vinegar, sugar, salt, and other residues, leaving it looking untidy. In such cases, simply wipe the countertop with warm water and soapy water; for stubborn stains, use a scouring pad to remove them.
If you have mischievous little ones at home, you may also have to deal with ink marks. Start by wiping away surface stains with a damp cloth, then use an eraser to remove any remaining traces. If the marks persist, mix laundry detergent with water in a 1:0.5 ratio—this creates a thicker paste with good friction. Let the paste sit on the surface for about five minutes, then scrub gently with a small brush until the stains are gone. Finally, rinse thoroughly with clean water.
Since kitchens often have plenty of metal cookware, unsightly water stains and rust inevitably appear on countertops. To tackle these rust marks, first wipe the surface with a damp cloth to remove loose grime, then soak the area with toothpaste, white vinegar, or 84 disinfectant for about 10 minutes, and finally scrub it clean with a cloth—your stains should come off easily.
In everyday use, quartz countertops should also be protected from scratches and abrasions caused by external forces. For example, avoid cutting meat or vegetables directly on the surface; instead, place a thick cloth underneath before setting down the cutting board. Do not scrub with steel wool, nor use sharp tools such as knives or drills that could cause mechanical damage.
Quartz stone is crafted from predominantly quartz sand, combined with a small amount of resin, pigments, and accelerators, through a series of rigorous manufacturing processes. Its exquisite craftsmanship gives it superior heat resistance compared to countertops made from other materials. For everyday use, employing heat‑resistant mats or trivets can better protect the countertop’s surface, especially along the edges.
The primary substances that can cause mild corrosive damage to quartz countertops are cleaning agents containing bleach, corrosive agents, rosin oil, highly alkaline compounds, xylene, toluene, potassium hydroxide, caustic soda, dichloromethane, trichloroethane, or any other similar chemicals. Such cleaning agents should be avoided when cleaning quartz countertops.
