对稻壳进行碳化得到的稻壳焦压制成型耐酸、耐热隔热材料并研究其性能。通过浸酸、高温、隔热及力学等实验研究表明,稻壳焦隔热材料在酸性介质和高温环境中具有较高的力学强度和优良的体积稳定性,稻壳焦的多孔性和其碳质粒子的红外阻隔作用、硅质粒子的化学和高温稳定性赋予其制品优良的隔热效应和耐酸耐热特性,其SiO2粒子所具有的水硬胶凝性起着增强作用,提高了隔热制品的力学强度。
Husk carbonization obtained by the Husk coke pressure-resistant acid and heat insulation materials and study its performance. Experimental studies on pickling, high temperature, heat insulation and mechanics show that the husk thermal insulating material has high mechanical strength and excellent volume stability in acid medium and high temperature environment, and the husk coke porosity and carbon The infrared blocking effect of the particles, the chemical and high temperature stability of the silica particles give their products excellent thermal insulation properties and acid and heat resistance characteristics. The water-cementing property of the SiO2 particles plays a role in enhancing the thermal insulation Mechanical strength of products.
