Preparation method of fly ash and slag foamed ceramic
The invention discloses a preparation method of fly ash and slag foamed ceramic, and belongs to silicate foamed ceramic materials. Slag and fly ash are used as raw materials, water glass is used as an adhesive, water glass curing components contained in the fly ash and the slag are used for blending to achieve proper hardening time, a foam blank is prepared by stirring for foaming or adding foam, the blank curing time and the foam decay time are balanced, and the green body is sintered at the low temperature of about 850 DEG C after being dried. The formula is exquisite, the process is reasonable and the cost is low. The apparent density of the product ranges from 0.15 g/cm<3> to 0.65 g/cm<3>, and the product has a hydrophilic type and a hydrophobic type. The method has a large application prospect in the fields of filtration, adsorption, sound absorption, noise reduction, heat preservation and heat insulation.
本发明公开了一种粉煤灰、炉渣泡沫陶瓷的制备方法，属硅酸盐泡沫陶瓷材料。以炉渣、粉煤灰为原料，以水玻璃为粘接剂，利用粉煤灰、炉渣所含水玻璃固化成分，调配出合适的硬化时间，以搅拌发泡或加入泡沫制成泡沫坯体，坯体固化时间与泡沫衰减时间达到平衡，干燥后的坯体，经850℃左右低温烧结而成。其配方精巧、工艺合理，成本低廉。产品表观密度在0.15g/cm3到0.65g/cm3之间，具有亲水、憎水两个类型。在过滤、吸附，吸音、降噪，保温、隔热领域有大量应用的前景。
