On August 9th, SCBX Co., Ltd. independently developed and independently invested by SCBX Fiberglass Group Co., Ltd., the first domestic pilot base project to produce basalt continuous fiber by the pool kiln method in Deyang, Sichuan Ignition in Luojiang District. At present, the national basalt continuous fiber production capacity is less than 30,000 tons, and the market demand is large. The total investment of this ignition project is 90 million yuan, which can produce 8,000 tons of basalt continuous fiber annually.
Basalt fiber
The main components of basalt are silica, alumina, iron oxide, calcium oxide, and magnesium oxide (with a small amount of potassium oxide and sodium oxide). The silica content is the largest, accounting for about 45 to 50 percent. about. Basalt fiber is a continuous fiber drawn from platinum-rhodium alloy wire drawing plate after melting the basalt material at 1450 ℃ ～ 1500 ℃. Its strength is equivalent to that of high-strength S glass fiber.
China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, and basalt fiber) for development. It has the characteristics of high strength, good temperature resistance, oxidation resistance, and radiation resistance. It is the most likely Take the lead in making new materials stronger and bigger globally. Basalt continuous fibers have been widely used in fiber-reinforced composite materials, friction materials, shipbuilding materials, thermal insulation materials, the automotive industry, high-temperature filter fabrics, and protection fields.
Remarks:
The pond kiln is mainly composed of a melting pond built with refractory bricks and a heat storage room or a heat exchange room. The raw material is added from one end of the melting tank, and after the melting, clarifying, cooling and other stages, it is drawn out from the other stage for molding. It is a kind of glass melting furnace. Commonly used to produce glass fibers.
