Description
Technical Field
The invention belongs to the technical field of silica bricks in refractory materials, and particularly relates to nano foam mud for a light silica brick.
Technical Field
Along with the increasing shortage of energy sources, the development, production and use of energy-saving materials for high-temperature industry are increasingly emphasized by various countries. The light refractory material has the advantages of light weight, high porosity, small volume density and low heat conductivity, and thus has obvious energy saving effect, wide application in high temperature industry and functions of maintaining heat, saving energy and lowering consumption. The silica brick has the characteristics of high refractoriness under load, good high-temperature volume stability, no shrinkage after long-term use and the like, and is widely applied and researched in a light refractory material system. At present, there are many methods for manufacturing light silica bricks at home and abroad, and among them, a foam method and a mechanical pressing combustible method are widely applied.
The machine-pressing combustible method has a significant disadvantage that the raw materials are unevenly distributed in the mixing process and the machine-pressing process, particularly, combustible materials are difficult to be evenly mixed in the dry mixing process and often have particle segregation, so that the microstructure of the material after being fired is uneven, such as: some parts have high porosity, and some parts have low porosity; further influencing the stability of the properties of the light material, such as high-temperature volume stability, refractoriness under load, thermal conductivity and the like.
The product prepared by the foam method has light specific gravity and better heat insulation performance, so that enterprises for industrially preparing silica bricks by the foam method are few. The light silica brick prepared by the foam method has high porosity, uniform hole distribution and good hole connectivity. However, the foam method for preparing the light-weight silica brick heat-insulating material has the obvious defects that the foaming is not easy, the stability of the foam framework is poor, the foam is not uniform when the foam slurry is prepared, the foam framework is easy to loosen and collapse, the mechanical property and the thermal property of the light-weight heat-insulating silica brick are further reduced, the time and the labor are consumed in the preparation process, and the raw materials are wasted.
