Impact-resistant and acid-invasion-resistant plastic refractory for incinerator lining and preparation method thereof
The invention discloses an impact-resistant and acid-invasion-resistant plastic refractory for an incinerator lining, which comprises the following raw materials: 58-93 parts by weight of sintered tabular corundum; 11-24 parts by weight of synthetic mullite; 8-38 parts by weight of fused chromium oxide; 3-12 parts by weight of soft clay; 2-17 parts by weight of desiliconized zirconia ultrafine powder; 1-22 parts by weight of silicon carbide; 1-8 parts by weight of tartaric acid mixed citric acid; and 8-14 parts by weight of a binding agent. The impact-resistant and acid-invasion-resistant plastic refractory for the incinerator lining has the characteristics of relatively low after-combustion linear change rate, stable high-temperature volume stability, excellent high-temperature toughness,relatively high wear resistance and acid resistance, good thermal shock stability, relatively good pressure resistance and bending resistance and the like, has the maximum use temperature of 1500 DEGC, and can be used as a garbage incinerator lining body, and the service life on various garbage incinerators can be prolonged by more than three times compared with traditional amorphous materials.
本发明公布了一种焚烧炉内衬用抗冲击耐酸侵耐火可塑料，包括如下原料：烧结板状刚玉58‑93的重量份；合成莫来石11‑24的重量份；电熔氧化铬8‑38的重量份；软质粘土3‑12的重量份；脱硅氧化锆超细粉2‑17的重量份；碳化硅1‑22的重量份；酒石酸混合柠檬酸1‑8的重量份；结合剂8‑14的重量份。本发明制得的焚烧炉内衬用抗冲击耐酸侵可塑料具有较低的烧后线变化率、稳定的高温体积稳定性、优越的高温韧性、较高的耐磨性能和抗酸性能、良好的热震稳定性、较好的耐压和抗弯折等特点，其最高使用温度为1500℃，可作为垃圾焚烧炉衬体使用，在各种垃圾焚烧炉上使用寿命可比传统不定形材料提高3倍以上。
