Artificial quartz stone is a kind of artificial stone, which is made of unsaturated polyester resin (UPR) as the binder, quartz sand and glass particles as the main aggregate, and quartz powder as the main filler. Quartz stone inherits the advantages of natural granite’s hard texture, corrosion resistance, wear resistance, as well as natural marble’s exquisite colors and high grade, and is widely used in indoor decoration and decoration fields such as kitchens, bathrooms, windowsills, restaurants, and other countertops. The main aggregates and fillers in the quartz stone plate are quartz sand and quartz powder. Except for a few high-end products with high whiteness and permeability, the requirements are generally low, mainly for whiteness, permeability, impurities and particle grading. As a manufacturer of quartz sand grinding mill, HCMilling(Guilin Hongcheng) will introduce the processing technology and index requirements of quartz powder for plate.

The quartz powder used in the board is divided into ordinary quartz powder and modified quartz powder (i.e. quartz powder treated with surfactants). Modified quartz powder improves compatibility with resin and can reduce resin dosage. The surface modifier of quartz powder is mainly silane coupling agent, and the surface chemical modification methods mainly include dry modification, wet modification and chemical coating modification. Dry modification is to add a small amount of diluent and silane to the treatment agent. Under the conditions of high-speed stirring, dispersion and certain temperature, the treatment agent is added to quartz powder in spray form, and discharged after stirring for a certain time. Wet modification is to use the treatment liquid mixed with the prepared surface modifier and auxiliary agent to modify the surface of quartz sand powder under the conditions of agitation, dispersion and certain temperature, and then dehydrate and dry it. Mechanical grinding and chemical coating modification refers to the addition of modifier under the action of mechanical force or in the process of fine grinding and quartz sand ultra-fine grinding mill, and the surface modification of quartz sand particles is carried out as the particle size decreases. The current surface modification technology of quartz powder seriously lags behind the development of the quartz industry. The close relative product of quartz stone – resin based artificial granite, which uses calcium powder as a filler, has made significant progress in surface modification technology, with an oil absorption rate of below 17%. On the other hand, the modified quartz powder has an oil absorption rate of around 20% for a long time, resulting in high resin consumption and high costs for quartz stone boards. Additionally, it also affects some of the properties of quartz stone products, such as expansion coefficient, hardness, etc, All have adverse effects.

The higher the whiteness of quartz powder, the higher the price, and the higher the whiteness, grade, and price of the produced quartz stone board. The higher the transparency of quartz powder, the higher the price. The produced quartz slate has a good texture and a strong three-dimensional texture, which can better simulate the texture and texture of natural stones. The commonly used quartz powder mesh numbers for sheet metal manufacturers include: 100-200 mesh, 325 mesh (or 400 mesh), 800 mesh, 1250 mesh, etc. HCMilling(Guilin Hongcheng), as the manufacturer of quartz sand grinding mill, our quartz sand Raymond mill, quartz sand vertical mill, quartz sand ultra-fine vertical mill and other equipment can process 80-2500 mesh quartz sand powder, which can meet the processing needs of high-grade quartz powder for plates.
