China is the world’s largest producer of silica fume, accounting for about 70% of the global production. The main production centers are located in the provinces of Henan, Shandong, and Shanxi.0
Silica fume properties
ซิลิกาฟูม is a byproduct of the smelting process in the silicon and ferrosilicon industry. มันเป็นการปรับ, powdery material with a high content of silicon dioxide (SiO2). Silica fume has a number of properties that make it a valuable industrial material, รวมทั้ง:
- กิจกรรมปอซโซลานสูง: Silica fume reacts with calcium hydroxide in cement to form calcium silicate hydrate, ซึ่งช่วยเพิ่มความแข็งแรงและความทนทานของคอนกรีต.
- การซึมผ่านต่ำ: Silica fume fills the pores in concrete, making it more impermeable to water and other fluids.
- Good thermal insulation properties: Silica fume can be used to make lightweight, heat-insulating materials.
- Fire resistance: Silica fume is a fire-resistant material that can help to protect structures from fire damage.
Silica fume applications
The main uses of silica fume in China are in the production of concrete, วัสดุทนไฟ, and thermal insulation materials. It is also used in the manufacture of composites, สี, และพลาสติก.
- คอนกรีต: Silica fume is used as a pozzolan in concrete. Pozzolans are materials that react with calcium hydroxide in concrete to form a cementitious material. This reaction improves the strength, ความทนทาน, and fire resistance of concrete.
- วัสดุทนไฟ: ซิลิกาฟูมใช้ในการผลิตวัสดุทนไฟ. Refractory materials are used to line furnaces and other high-temperature applications. Silica fume helps to improve the thermal insulation and resistance to erosion of refractory materials.
- Composite materials: Silica fume is used in the production of composite materials. Composite materials are made from two or more materials that have different properties. Silica fume is used to improve the strength, ความเหนียว, and wear resistance of composite materials.
Silica fume price in China
The quality of silica fume produced in China varies. The best quality silica fume is produced by the wet process, which produces a product with a high specific surface area and a low content of impurities. The wet process is more expensive than the dry process, but it produces a higher quality product.
The cost of silica fume in China varies depending on the quality and the grade. The average ราคาซิลิกาฟูม in China is around US$200 per ton. อย่างไรก็ตาม, the price can be higher for high-quality silica fume or for silica fume that meets specific standards.
