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 potassium water glass as an adhesive, sodium hydrosilicate 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 a compact acid resistant adhesive mortar, which is prepared by evenly mixing the components of 20-40 wt% of sodium silicate, 3-7wt% of sodium fluosilicate, 50-70wt% of glass-ceramic powder and industrial porcelain powder or glass-ceramic powder, quartz powder and industrial porcelain powder, and 1-3wt% of furfuryl alcohol in proportion at the normal temperature, adding a proper amount of water, stirring and milling to form the acid resistant adhesive mortar in a smearing state, and is used by filling in curing time. The invention has strong acid and alkaline corrosion resistance, high compression strength and bonding strength, short final setting time, simple preparation process and convenient use and operation, and can be widely applied in bonding and filling corrosion resistance and heat preservation lining bodies in the industries such as chemical engineering, smelting, petrifaction, sulfuric acid, papermaking, environment protection and the like.

Description

technical field [0001] The invention relates to a colloid, in particular to an acid-resistant cement with good compactness. 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. 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 potassium water glass as an adhesive, sodium hydrosilicate 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 re...
