The invention discloses a processing technology of tempered glass, which comprises the following steps: step 1, heating, taking flat glass, and heating at 650°C-750°C for 3-10min; step 2, cooling, taking out the glass, and spraying evenly on both sides of the glass Blow air to cool the glass uniformly to 200-250°C; step 3, slowly heat the glass to 270-280°C, and keep it warm for 10-25min; step 4, cool the glass in step 3 to room temperature to obtain tempered glass. The present invention has the following advantages and effects: gamma ray irradiation is used in the cooling process to promote the transformation of nickel sulfide in the glass from the high-temperature phase α-NiS to the low-temperature phase β-NiS, reducing the self-explosion of the prepared tempered glass; secondly, step 3 In the process, the glass is slowly heated to 270-280°C, and under the irradiation of gamma rays, it can further promote the transformation of nickel sulfide from the high-temperature phase α-NiS to the low-temperature phase β-NiS, further reducing the self-explosion of the tempered glass and reaching the strength High, low self-explosion rate of tempered glass, safe to use.

The invention discloses a high-toughness toughened glass and a preparation method thereof, comprising the following raw materials in parts by weight: 600-700 parts of quartz sand, 125-165 parts of fluorite, 90-115 parts of potassium feldspar, iron-containing compound 75-90 parts of fiber, 50-65 parts of silicon carbide fiber, 95-110 parts of alumina fiber, 35-45 parts of zinc oxide, 40-55 parts of zirconium boride, and 40-60 parts of sodium bismuth titanate. The present invention selects the constituent raw materials of high-toughness tempered glass and optimizes the ratio of the constituent raw materials of high-toughness tempered glass. Glass has high impact strength and bending strength, good toughness, good mechanical properties, and is not easy to damage; the surface compressive stress is large, and the self-explosion rate is low.

The invention belongs to the technical field of materials and particularly discloses tempered glass and a manufacturing process thereof. The tempered glass comprises a tempered glass substrate and an explosion-proof layer. The tempered glass substrate comprises, by weight, 20-60 parts of silicon dioxide, 10-15 parts of limestone, 3-5 parts of borax, 5-8 parts of calcium carbonate, 10-16 parts of feldspar, 3-8 parts of bauxite, 5-13 parts of calcium silicate, 2-5 parts of sodium oxide, 2-4 parts of lithium oxide, 4-8 parts of bismuth oxide, 7-9 parts of aluminium sesquioxide, 1.5-2.5 parts of macrogol ester, 3-7 parts of copper sulfate pentahydrate, 5-11 parts of potassium permanganate, 3-6 parts of sodium hydroxide and 2-6 parts of a clarifying agent; the explosion-proof layer is composed of, by weight, 15-30 parts of polyvinyl alcohol, 30-60 parts of butyraldehyde, 15-30 parts of hydrochloric acid, 8-12 parts of plasticizer and 6-9 parts of an additive. According to the tempered glass and the manufacturing process thereof, a PVB middle membrane is additionally arranged between two layers of tempered glass, good binding power is achieved for inorganic glass, possibility of spontaneous explosion of the tempered glass can be effectively reduced, and the performance of the prepared tempered glass is far superior to conventional tempered glass.

The invention discloses a solid mold for tempering glass molding, and particularly relates to a solid mold for curved tempered glass molding. The invention aims to solve the technical problems of difficult molding, low yield and poor appearance quality of curved tempering glass. The mold is prepared through the following steps: 1, covering at least one layer of glass fiber on the inner surface of the curved glass as a convex glass wool cloth; 2, adding a lap of steel bar on the inner surface of the convex glass wool cloth; 3, paving at least one layer of glass wool cloth on the steel bar as a concave glass wool cloth; and 4, coating a fixing liquid on the inner surface of the concave glass wool cloth and drying at room temperature for 25-35 min. Adopting the technical scheme, the self-destruction rate of the curved tempering glass is reduced from 1% to 0.3%.
