1. Industrial silicon
Industrial silicon is obtained by smelting in an electric arc furnace using quartz sand as raw material and carbonaceous materials as reducing agent. Commonly used reducing agents mainly include charcoal, petroleum coke, coal, etc., which can reduce metallic silicon from silica. In the photovoltaic industry, industrial silicon is the main raw material for manufacturing polysilicon and other materials; industrial silicon is also the main raw material for organic silicon, used to produce silane, silicone, silicone oil and other products; in the alloy industry, industrial silicon is mainly used as a non-ferrous material. Additives to base alloys. When silicon is added to certain non-ferrous metals, it can improve the strength, hardness and wear resistance of the base metal. Sometimes it can also enhance the casting performance and welding performance of the base metal. Industrial silicon has become the main upstream product in the silicon-based new material industry chain and the core raw material for many important sectors of the national economy.
2. Silicon carbide
Silicon carbide is an inorganic non-metallic material that has developed very rapidly in recent years. Silicon carbide ceramics have high hardness, strong high-temperature load-bearing capacity, oxidation resistance, wear resistance, large thermal conductivity, small thermal expansion coefficient and resistance to acid and alkali chemical corrosion. With its excellent properties, it has broad application prospects in high-tech fields such as semiconductors, electronics, automobiles, atomic energy, environmental protection and energy conservation. One of the methods for preparing silicon carbide powder is the carbothermal reduction method, which uses coke or kerosene in a high-temperature electric furnace to reduce silicon dioxide in quartz sand to produce silicon carbide ceramic bulk materials, which are then mechanically crushed and classified through a grinding mill. Silicon carbide powders of different particle sizes are obtained through other processes.
3. Quartz crucible
Quartz crucible is a subdivision of quartz glass products and has the properties of cleanliness, homogeneity, and high temperature resistance. It is currently widely used in the production process of refining crystalline silicon in the fields of solar energy and semiconductors, and is a consumable in the production process of crystalline silicon. Benefiting from the accelerated expansion of silicon wafer production capacity and the increased penetration of N-type silicon wafers, the demand for high-purity quartz sand and quartz sand crucibles is expected to grow rapidly. The production of quartz crucible is to put high-purity quartz sand into a rotary molding mold that can be tilted at any angle, use centrifugal force and manual molding of the molding rod, move the crucible-shaped rotating device to the electrode rod, and then send electricity to the electrode Start the arc and insert it into the formed powder cavity, and start the vacuum system at the same time to quickly melt it into fused quartz in the shape of a crucible. After cooling, take it out to complete the production of a quartz crucible blank.
4. Photovoltaic ultra-white glass
As a new material, ultra-white glass has broad application prospects in the solar photovoltaic industry, high-end cars, high-end buildings, high-end gardening buildings, and high-end furniture due to its high light transmittance and crystal clear characteristics. Photovoltaic glass production process: quartz sand, soda ash and other raw materials are melted into glass liquid, and ultra-white rolled glass original sheets are obtained through processes such as rolling, annealing, and cutting. The original film is then coated and tempered to further improve the light transmittance and strength, becoming a finished photovoltaic glass.
5. Glass fiber
Glass fiber is an inorganic non-metallic material with excellent properties. It has many types. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Glass fiber is made from quartz sand, pyrophyllite, kaolin, limestone and other ores as raw materials through high-temperature melting, drawing, drying, winding and other processes. Its single filament diameter ranges from a few microns to more than 20 microns, which is equivalent to one 1/20-1/5 of a hair, each bundle of fiber strands is composed of hundreds or even thousands of single filaments.
6. Artificial quartz stone
Artificial quartz stone is a composite material made by curing and molding of 93% to 95% quartz and about 7% unsaturated polyester resin adhesive, colorants, curing initiators and other auxiliary reagents. It is hard, dense in structure, rich in color, wear-resistant, pressure-resistant, high-temperature resistant, corrosion-resistant, and anti-penetration. It is widely used in the market and is the fastest growing variety of artificial stone.
7. Calcium silicate board
Calcium silicate board is an inorganic building board with high strength and stable performance made from siliceous materials, calcium materials and reinforced fibers through slurry molding, slab compaction and autoclave curing. It has superior properties such as fire protection (reaching A1 level standard), thermal insulation, anti-corrosion and anti-moth, waterproof and moisture-proof, sound insulation and sound-absorbing, lightweight and high-strength, green and harmless, etc. It is more energy-saving, environmentally friendly, earthquake-resistant, and impact-resistant than traditional boards, and can be widely used It is used in the fields of interior and exterior wall insulation and decoration of houses, ceilings and cabin partitions, billboards, etc. The design and installation are highly malleable and save time and labor. Quartz sand is one of the most important raw materials in calcium silicate products, accounting for 40% of the raw material quality of calcium silicate boards.
Quartz sand downstream products have a wide variety of products, are widely used, and have good market prospects. As a quartz sand Raymond mill manufacturer, the Raymond mill produced by Hongcheng can process quartz sand powder of 80-2500 mesh.
