Quartz vs. Sintered Stone Which is Better?
- tags：

Quartz and sintered stone are currently widely used in areas such as cabinets, floors and wall decoration. They have different properties and advantages, and choosing which material is better depends on the specific scenario and personal preferences of the customer. The following is an in-depth analysis of the differences between quartz and sintered stone from the three perspectives of composition and manufacturing process, board strength and aesthetics.

 

1. Composition and Manufacturing Process

Quartz: Quartz is made of about 90-95% natural quartz crystals mixed with resins, polymers and pigments. The resin binds the quartz particles together to make it a strong and impermeable surface. The manufacturing process makes the quartz surface highly uniform, with a certain aesthetic and practicality.

 

Sintered Stone: It is a new type of porcelain material made from natural raw materials through a special process, with the help of a 16,000-ton press, combined with advanced production technology, and fired at a high temperature of more than 1200°C. Sintered stone is subjected to high temperatures and pressures during the production process, making it very strong and durable, with a natural stone texture. OEM sintered stone is also available upon request.

2. Plate Strength

Quartz:

Very durable, resistant to scratches, impacts, and stains.

However, quartz is less resistant to high temperatures than sintered stone, and exposure to high temperatures (such as hot pots) may damage the surface.

 

Sintered Stone:

Extremely durable, with strong resistance to wear, impact, heat, and UV rays.

Ability to withstand high temperatures (up to 1500°F or 800°C), making it an ideal choice for high-temperature environments such as kitchen countertops. Some OEM sintered stone are inlaid with appliances such as induction cookers.

3. Aesthetics and Design Options

Quartz:

Available in a variety of colors, textures, and finishes.

Usually with a uniform pattern, quartz has a consistent texture and color due to the manufacturing process, making it suitable for those who like a uniform style.

There are styles that imitate natural stone, as well as monochrome or striped designs, which meet a variety of design needs.

 

Sintered stone:

Provides a wide range of colors, textures and surface treatments, usually imitating natural stone such as marble, granite, etc.

Sintered stone has a very diverse appearance, with natural textures and unique textures, which is particularly suitable for customers who pursue personalized design and are used to design whole house.

Because ultra-thin luxury sintered stone can be produced (as thin as 3cm), it can be composited on door panels such as cabinets and wardrobes, presenting a luxurious design sense.

 luxury sintered stone

In general, quartz and sintered stone are both very good materials, and the specific choice depends on your project requirements. If it is used in places where high temperature resistance is required (such as kitchens), sintered stone may be a better choice.

The production process of sintered stone
- tags：

Sintered stone is a new type of material made by ultra-high temperature sintering. It is widely used in TV background walls, kitchen countertops, bathrooms and other fields. The production process of sintered stone includes several key steps, and each step needs to be precisely controlled.

 

1. Choose the right raw materials

The production of sintered stone begins with the selection of raw materials, usually natural ores, clay and other raw materials. These raw materials are carefully selected to ensure good physical properties such as hardness, wear resistance and heat resistance. In order to meet the needs of different customers, different pigments are also added to create unique color effects.

2. Batching and mixing

The raw materials are proportioned in a certain proportion and mixed by automated equipment. When batching, some special additives such as plasticizers or anti-fouling agents are also added to improve processing performance and long-term use.

 

3. Pressing and molding

The mixed raw materials will be pressed into the shape of plates or bricks by high-pressure equipment. During the pressing process, the raw materials are tightly combined under high pressure to form a dense material structure. This step ensures the high strength and good impact resistance of the sintered stone. The design of the mold also provides sintered stone products of different sizes and shapes according to market demand.

 

4. Sintering process

The pressed raw materials are sintered at a high temperature of about 1300℃, and the minerals in the raw materials react chemically to form a strong and durable material structure. The sintering temperature and time of the sintered stone must be controlled very accurately to ensure that the hardness and glossiness of the final product meet the established requirements.

5. Cooling and post-processing

After sintering, the sintered stone needs to be cooled slowly to avoid cracks or deformation due to temperature changes. After cooling, the sintered stone will be cut, ground and polished to improve its surface smoothness.

 

6. Inspection and packaging

Finally, the batch of sintered stones will be sampled to check whether their size is correct and whether the gloss is sufficient. Finally, the sintered stones are packaged and sent all over the world.

Through the fine production process, sintered stones have the advantages of high hardness, high temperature resistance, and strong stain resistance. They are widely used in modern architecture and home decoration, meeting people's dual needs for beauty and durability.

How can natural - stone stair treads be made durable?
- tags：
Natural granite or marble stairs are very common products. They are indispensable for stair treads in home decoration, hotels, airports, subways, and high-speed railway stations. We often use some black granite and white marble to make the treads and risers of the stairs. These natural stones are sturdy and durable, and can also enhance the grade of the building. However, since there are many people walking on them, the steps and risers need to be sturdy to ensure that they will not be broken or fractured during use and to guarantee safety. Nevertheless, it is not difficult for us to find that due to unreasonable designs, the stair treads are prone to breakage, which affects both their appearance and safety.

 

To prevent the occurrence of chipping and corner-breaking phenomena on the stair treads, the following six points should be noted during the design:
(1) The depth of the grooves on the stair treads should not be greater than 2 mm.
(2) The spacing between the grooves on the stair treads should be greater than 10 mm.
(3) The overhanging length of the front end of the stair tread panel should not exceed 5 mm beyond the riser.
(4) The distance between the first groove on the stair tread and the front end of the stair tread is preferably greater than 20 mm.
(5) The number of grooves on the stair tread should not exceed five.
(6) The thickness of the stair tread stone should be greater than 20 mm.
