Abstract

The invention discloses a method for producing high-alkali flyash continuous fibers with high-volume flyash. The method includes the steps that 77-80% of flyash, 10-11% of sodium oxide, 4-6% of potassium oxide, 2-4% of magnesium oxide and 2-6% of an additive are taken; the materials are mixed and conveyed to a flame tank furnace or an electric melting furnace through a feeding machine, after being molten for 2-3 h at the temperature of 1600 DEG C-1650 DEG C, the materials flow into a bushing plate through a material channel, and the high-alkali flyash continuous fibers are obtained by carrying out drawing at the temperature of 1350 DEG C-1400 DEG C through drawing equipment. The high-alkali flyash continuous fibers can serve as waterproof and damp-proof materials such as a storage battery spacer, pipeline wrapping fabric and a mat. The waste flyash can be effectively used to achieve cyclic utilization of resources.

Description

technical field [0001] The invention relates to the field of fly ash fiber manufacturing methods, in particular to a high-alkali fly ash continuous fiber produced by using high-volume fly ash and a preparation method thereof. Background technique [0002] Since my country's recent electric power industry is still dominated by thermal power generation, the annual discharge of fly ash is more than 300 million tons, the discharge of fly ash wastes a lot of water resources, and ash storage plants occupy a lot of cultivated land. Although the field of comprehensive utilization of fly ash continues to expand , but the annual utilization rate is only about 70%. [0003] After development and research in our country, fly ash has been widely used in construction, building materials, water conservancy and other departments. The comprehensive utilization of fly ash mainly includes several aspects, such as conventional utilization of cement raw materials, cement mixture materials, large...
