▎ 摘  要

NOVELTY - Preparing high yield explosion-proof toughened glass comprises grinding quartz sand, limestone, aluminous soil bauxite, sodium hydroxide, mirabilite, feldspar, graphene, toner and clarifying agent, drying, mixing to obtain component A, dissolving graphene and cadmium oxide water, wet-milling, concentrating, spray drying, dry grinding, passing through 800 mesh sieve, controlling the moisture to obtain component B, mixing component A and B, heating the mixture to obtain a evenly formed liquid glass processing the liquid glass, cutting, edging, washing, and drying the processed liquid glass, heating the glass in a tempering furnance, rapidly heating, intermittently blowing, cooling the glass, blowing, cooling the glass, transferring the glass to quartz glass protective vessel filled with nitrogen, bombarding the glass with a pulsed laser and ultrasonically cleaning and drying with cold air and allowing to cool to room temperature. USE - The method is useful in preparaing high yield explosion-proof toughened glass. ADVANTAGE - The method: utilizes pulse laser bombardment technique thus reducing the volume of nickel sulfide; and completely eliminates the self explosion of glass. The glass: has less than 0.001% probability of self explosion. DETAILED DESCRIPTION - Preparing high yield explosion-proof toughened glass comprises (1) grinding quartz sand, limestone, aluminous soil bauxite, sodium hydroxide, mirabilite, feldspar, carbon powder and clarifying agent to 400-600 mu m, drying to a 2-4% moisture content, mixing in a mixer for 1.5-2 minutes to obtain component A, dissolving graphene and cadmium oxide are dissolved in 20-50 times of water, wet-milling, concentrating, spray drying, dry grinding, passing through 800 mesh sieve, controlling the moisture to0.5-1% to obtain component B, mixing component A and B for 3-5 minutes, (2) heating the mixture obtained in the step (1) at 75-800 degrees C in a melting furnace for 10-15 minutes, to obtain a evenly formed liquid glass without bubbles that meets the molding requirements, (3) processing the liquid glass, (4) cutting, edging, washing, and drying the processed liquid glass, (5) placed the glass in tempering furnace, heating to 120-150 degrees C for 2-3 minutes, (6) rapidly heating to 600-650 degrees C within 2-3 minutes, allowing it to stand for 5-8 minutes, (7) move the glass into the windshield, intermittently blowing for 1-5 seconds, stopping for 1-25 seconds and for 30-60 seconds, cooling the glass to 470-490 degrees C, (8) blowing for 2-3 minutes, cooling the glass to 60-80 degrees C, (9) transferring the glass to quartz glass protective vessel filled with nitrogen, bombarding the glass with a pulsed laser for 8000-12500 times/m2, moving the bombardment device in both translational and downward directions, (10) removing the glass from the quartz glass protection vessel, ultrasonically cleaning and drying with cold air at 15-25 degrees C and allowing to cool to room temperature.
