Formula and technology of unfired honeycomb ceramic regenerator
The invention discloses a formula of an unfired honeycomb ceramic regenerator. According to industry routines, the formula is obtained through the steps of: firstly compounding a main formula according to the following raw materials in percentage by mass: 80%-86% of corundum mullite, 10%-12% of kaolin, 3%-5% of alumina micro-powder and 1%-3% of monox micro-powder; then compounding an auxiliary formula through using the total mass of the raw materials of the main formula as a benchmark, wherein the auxiliary formula comprises the following components in percentage by mass: 6% of chopped zirconium-aluminum ceramic fibers, 2.5% of carboxyl methycellulose and 0.5% of stearic acid; and then compounding liquid according to the total mass of the raw materials of the main formula and the auxiliary formula, wherein the liquid comprises the following components in percentage by mass: 20% of water and 5%-7% of aluminum phosphate. The invention further discloses a corresponding technology. According to the formula and the technology which are disclosed by the invention, a manufacture cost is lowered, energy consumption is reduced, a qualified drying rate of products achieves 98%, compressive strength is larger than or equal to 8MPa, and breakage requirements of transporting and mounting the unfired honeycomb ceramic regenerator are satisfied.
