Problems solved by technology

Most of the cement currently used to bond acid-resistant bricks and fill the gaps between acid-resistant tiles is an inorganic compound formed by mixing sodium water or feed water glass as an adhesive, sodium hydrogen silicate or sodium fluorosilicate as a curing agent, and acid-resistant materials as a filler. Quality-type gelling, but the acid-resistant cement currently used is not strong enough in corrosion resistance, heat resistance and impermeability are not high, and the final setting time is relatively long

Abstract

The invention discloses aciduric daub, which comprises the following raw materials in part by mass: 30-50 parts of sodium water glass, 4-6 parts of sodium fluosilicate and 55-60 parts of porcelain powder; and the porcelain powder is mixture of glass-ceramic powder and industrial porcelain powder. The mass ratio of the glass-ceramic powder to the industrial porcelain powder is 1:1-1:5. The aciduric daub is composed of 35-45 parts of sodium water glass, 4.5-5 parts of sodium fluosilicate and 56-58 parts of porcelain powder. The invention has the advantages that the aciduric daub disclosed by the invention has high acid and alkali corrosion resistance, high compressive strength and high adhesive property; compared with the traditional aciduric daub, the aciduric daub has the cohesive strength of being improved by more than 8%; and the final setting time of the aciduric daub is shortened compared with that of the traditional aciduric daub.

Description

technical field [0001] The invention relates to a building material, in particular to an acid-resistant clay. Background technique [0002] In the industrial tower equipment of chemical industry, smelting, petrochemical, sulfuric acid, papermaking and environmental protection and other industries, acid-resistant tiles need to be filled, and the acid-resistant tiles must be bonded with acid-resistant cement to seal the tiles to prevent chemical liquids corrosion and penetration. At present, most of the cement used to bond acid-resistant bricks and fill the gaps between acid-resistant tiles is an inorganic compound formed by mixing sodium water or feed water glass as an adhesive, sodium hydrogen silicate or sodium fluorosilicate as a curing agent, and acid-resistant materials as a filler. However, the acid-resistant cement currently used is not strong enough in corrosion resistance, heat resistance and impermeability are not high, and the final setting time is relatively long...
