Quartz stone is an environmentally friendly and green new building material that is free of radioactive pollution and can be reused. It is based on the unsaturated polyester resin (UPR) or methacrylic resin (PMMA) organic polymer material as a matrix, quartz stone powder, particles, etc. as fillers, pigments, and other auxiliary agents are added, and it is a polymer formed by vacuum and high pressure. Composite materials.
The composition and production process of quartz stone:
Unsaturated polyester resin: The resin is used as the basic material of quartz stone, which has the function of bonding and curing. The resin currently used to make quartz stone usually includes o-phthalic, isophthalic, neopentyl glycol, isophthalic/neopentyl glycol, vinyl ester, acrylic, etc.
Filling material: The main component of the quartz stone filling material is silica, including quartz sand, quartz powder, and glass fragments. Its main functions are as follows: one is to fill the volume; the second is to enhance the texture of the quartz stone; the third is to enhance the mechanical properties of the quartz stone; the fourth is to act as combustion aid.
Pigment: The role of pigment in quartz stone is to adjust the variety of colors, which is rich in colors. In theory, any color can be formulated through various types of pigments.
Curing agent: A curing agent is an indispensable auxiliary in the production of quartz stone. Good quartz stone is cured at high temperatures.
Other additives: Resin is a polymer material. Appropriate addition of some additives can improve its process performance, increase production efficiency, improve the performance of quartz stone, and prolong its life.
The specific production process is as follows: firstly pulverize high-quality natural quartz sand, secondly purify it (the process removes metal impurities and avoids the radioactivity of the product), and then mix the raw materials and mix the quartz crystal (90 %-94%), resin (6%) and trace pigments are made into large-size plates through heterogeneous polymerization technology, and then the surface is polished and polished in more than 30 processes.
The scope of application and development direction of quartz stone:
At present, the development direction of quartz stone products is mainly in the countertops of the cabinet, the countertops of the bathroom, the bar counter, the coffee table, the ground, and the top surface of the inner wall. It can completely replace the natural stone, high-grade ceramics, wood, and metal decorative materials. At the same time, the proportion of quartz stone application is constantly changing. Quartz stone in the cabinet industry is becoming a new substitute product, and the proportion of floor stone decoration is increasing substantially. Because the hardness of quartz stone is very large, reaching 5-7 degrees on the Mohs, this brings certain difficulties to the processing technology of quartz stone. The consumption of whole cabinets is becoming more and more individualized, which has very high technical content for cabinet modeling, and it may leave flaws if you don’t pay attention to it. The hardness of quartz stone also has higher requirements for the splicing of quartz stone.
Quartz stone countertops refer to cabinet countertops made of quartz stone. Quartz stone countertops are made of broken glass and quartz sand. The advantages of quartz stone are that it is wear-resistant and not afraid of scratches, and it has good heat resistance, and can be used for large-area paving and wall coverings. It can be used as a variety of kitchen and bathroom countertops. Quartz stone is a new type of green and environmentally friendly stone artificially synthesized by more than 93% of quartz crystals plus resin and other trace elements.
Because this product is a brand-new decorative surface material made from quartz crystal ore as raw material, it is a product of a combination of natural beauty and high technology. This kind of quartz crystal ore itself has natural characteristics such as crystal clear, clear, beautiful color, luxurious, high hardness, no deformation, no discoloration, strong toughness, no radioactivity, strong acid-resistance, and other natural characteristics, so it is called “Jade Mine”. Quartz stone surface material made of this raw material combines many advantages of natural stone and artificial stone. It has been widely adopted and used by customers in most countries in the world, including Europe, America, Australia, the Middle East, and other countries. And it has been sold in large quantities to countries such as Italy, the United States, Spain, Turkey, Portugal, and other countries of origin of quartz stone. The price of quartz stone is still acceptable to the public.
The high-quality green environmental protection materials are soft and elegant in color, high in quality, and low in price. They are the best choice for green buildings. They are used for kitchen countertops, dining tables, bathroom countertops, window sills, bar counters, internal and external walls, floors, etc., suitable for apartments, office buildings, a wide range of requirements in different fields such as shopping malls, hotels, subway stations, airports, hospitals, and libraries.
