Abstract

The invention relates to the technical field of cyclic utilization of wastes, and particularly relates to a fiber-reinforced cordierite earthenware pot which includes, by weight, 30-40% of fly ash, 20-30% of magnesite, 10-15% of fine fibers, 5-15% of clay, and 10-30% of a sintering aid. The invention also relates to a method of manufacturing the cordierite earthenware pot, which includes the stepsof: 1) feeding the fly ash, magnesite, fine fibers, clay and sintering aid into a ball milling machine to prepare slurry; 2) performing slip casting to the slurry in the step 1) to make a green body,and finishing and glazing the green body; 3) sintering the green body in the step 2) in a kiln at high temperature to finally produce the cordierite earthenware pot. In the preparation method, the fly ash is utilized completely, thus avoiding environmental pollution.

Description

technical field [0001] The invention relates to the technical field of waste recycling, in particular to a fiber-reinforced cordierite casserole and a preparation method thereof. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. The main oxide composition of fly ash in thermal power plants in my country is: SiO 2 、Al 2 o 3 , FeO, Fe 2 o 3 , CaO, TiO 2 Wait. Fly ash is one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and cause pollution. Atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms. [0003] Now it is generally believed that the comprehens...
