Example Embodiment
[0025] Embodiment 1: Select 35% of sepiolite (Mg4Si6O15(OH)2 6H2O), 30% of expanded perlite (a mixture of SiO2, CaO, Al2O3, Na2O, Fe2O3, K2O, etc.), fumed silica (SiO2 ) 25%, inorganic powder hygroscopic agent 10%, appropriate amount of chemical stabilizer, 10% of the total material weight of water-soluble refractory adhesive is stirred and mixed, and the material in the formula, expanded perlite, plays a very good role in The basic filling and supporting function, the fumed silica monomer is fine, and has a good compacting effect. In addition, the curing of the water-soluble adhesive and the effect of the mold pressure strengthen the structural force of the core material. Interaction between sepiolite and hygroscopic agent quickly absorbs water, hardens and sets shape, and has excellent plasticity.
[0026] Embodiment two: select sepiolite (chemical composition is Mg4Si6O15(OH)2.6H2O belongs to the layered structure silicate mineral of orthorhombic (orthorhombic) crystal syst...
