Artificial quartz stone is another artificial stone product that is different from artificial granite. Its development has a history of several decades, and its demand is increasing with the development of architectural decoration. HCMilling(Guilin Hongcheng), as a manufacturer of quartz stone grinding mill, our quartz stone grinding mill have been widely used in artificial quartz stone production lines. The following is an introduction to artificial quartz stone production technology.

Raw materials:

Artificial quartz stone is made of natural quartz stone (sand, powder), silica sand, tailings slag and other inorganic materials (the main component is silica) as the main raw material, and is made of high molecular polymer or cement or a mixture of the two as the binding material. made of artificial stone. The basic raw materials of artificial quartz stone are quartz sand (powder), resin, pigment, curing agent, coupling agent and embellishment material. Using the above materials, products that meet the national industry standards and have the same quality as foreign countries can be prepared. In addition to the above materials, some manufacturers have prepared functional artificial quartz stone by adding fluorescent materials, flame retardants, antibacterial agents and other materials. This article focuses on the basic raw materials used in the production of artificial quartz stone.

2. Quartz powder: At present, the quartz sand (powder) used in artificial quartz stone on the market is mainly processed from quartz sandstone, quartzite and vein quartz. Divided by particle, the quartz powder used in artificial quartz stone refers to the powdered quartz whose particles are smaller than 325 mesh. The commonly used quartz powder products in the market are 325 mesh, 400 mesh, 600 mesh, 800 mesh, etc.; the processing flow of quartz powder using HLM quartz stone vertical roller mill: large stone Enter the warehouse→high pressure water washing→coarse crushing→fine crushing→vertical mill ball milling→wind selection. For the rinsing process, different methods are adopted according to the quality of the quartz ore. If the ore has few impurities, it can be processed directly; Wind separation is to use the difference in suspension speed between materials and impurities, and use the method of wind removal to remove impurities, which is composed of coarse crushing, fine crushing, wind conveying and other devices.

2. Resin: Resin is one of the basic raw materials of artificial quartz stone and plays a role in bonding. At present, there are two main resins used in artificial quartz stone: one is unsaturated polyester resin, and the other is polymethyl methacrylate resin (acrylic resin).

3. Other materials: Pigments are often used in artificial quartz stone to obtain products of different colors, which make them have superior decorative properties. The curing agent is an indispensable auxiliary in the production of quartz stone. Generally, artificial quartz stone is formed by high temperature curing. Curing agents are substances or mixtures that enhance or control the curing reaction of resins. In plastic compounding, a chemical additive added to improve the interface properties of synthetic resins and inorganic fillers or reinforcing materials. The coupling agent is generally composed of two parts: one part is an inorganic-philic group, which can interact with inorganic fillers or reinforcing materials; the other part is an organic-philic group, which can interact with synthetic resins. Some artificial quartz stone enterprises also add embellishment materials in order to enhance the decoration of the products. Commonly used embellishment materials are shells, transparent glass, stained glass, brass, fluorite, pyrite, sphalerite, etc.

Production Process:

The production of single-color products is relatively simple, that is, various raw materials are first stirred and mixed until uniform, and then sent to the distribution device for distribution, and then the distributed materials are sent to the pressing machine for high-frequency vibration compression molding in a vacuum state. The pressed quartz stone plate is then sent to the curing furnace for heating. After curing, it exits the curing furnace and is stacked vertically to cool to room temperature, and then polished and polished into a smooth plate. Plates can be cut into finished products of certain specifications according to customer requirements. The production process of multi-color artificial quartz stone products is relatively complicated. First, a variety of single-color artificial quartz stone mud materials need to be prepared, and then a variety of artificial quartz stone mud materials are placed in the mixing equipment for moderate stirring and mixing to obtain mixed mud materials. Then the mixed mud is sent to the distribution device for distribution. After the cloth is finished, the clothed material is sent to the pressing machine for high-frequency vibration pressing in a vacuum state. The pressed quartz stone plate is then sent to the curing furnace for heating and curing. After the curing is completed, it exits the curing furnace and is stacked vertically to cool to room temperature, and is then ground and polished into a smooth panel. Plates can be cut into finished products of certain specifications according to customer requirements.

The above describes the introduction of artificial quartz stone production technology. Among them, the HLM quartz stone vertical roller mill produced by HCMilling(Guilin Hongcheng) is the main equipment in the raw material preparation link in the artificial quartz stone production line, which is used to grind the artificial quartz stone raw material: quartz powder. HCM’s quartz stone grinding mill has the advantages of large output, stable operation, energy saving and environmental protection. It can grind 80-2500 mesh quartz powder, which provides a good equipment for the production of artificial quartz stone.
