Embodiment 1

[0020] Prepare cesium potassium salt solution as the coating solution, consisting of: K + : 40% (by K 2 SO 4 with KNO 3 According to the composition of 3:1), Na + (Na 3 PO 4 ): 1%, Cs + (CsNO 3 ): 0.5%, coating solution tackifier (starch): 10%, release agent (SnCl 4 ): 18%, surfactant (ROSO 3 Na): 0.5%, water: 30%, take 6mm thick 610×610mm float glass, finely grind the edges around, round the edges and corners and polish, then put it into the tempering furnace, and the heating time in the tempering furnace is 220 -300 seconds, spray the prepared salt solution to the glass surface at the same time, after the heating is completed, the glass enters the cooling section for rapid cooling, and the surface compressive stress value (MPa) of the glass is measured. See Table 1 for detailed process parameters.

Embodiment 2

[0022] Prepare cesium potassium salt solution as the coating solution, consisting of: K + : 60% (by KCl and KNO 3 According to the composition of 1:1), Na + (Na 3 PO 4 ): 5%, Cs + (Cs 2 CO 3 ): 1.5%, coating solution tackifier (bone glue): 1%, peeling agent (SnCl 4 ): 3%, surfactant (ROSO 3 Na): 1%, water: 28.5%, take 8mm thick 610×610mm float glass, finely grind the edges around, round the edges and rounded corners and polish, then put it into the tempering furnace, and the heating time in the tempering furnace is 300 -360 seconds, spray the prepared salt solution to the glass surface at the same time, after the heating is completed, the glass enters the cooling section for rapid cooling, and the surface compressive stress value (MPa) of the glass is measured. See Table 1 for detailed process parameters.

Embodiment 3

[0024] Prepare cesium potassium salt solution as the coating solution, consisting of: K + : 50% (K 3 PO 4 ), Na + (Na 3 PO 4 ): 5%, Cs + (CsNO 3 ): 1%, coating solution tackifier (starch): 0.5%, release agent (SnCl 4 ): 15%, surfactant (Rn + (CH 3 ) 3 Cl): 1.2%, water: 27.3%, take 10mm thick 610×610mm float glass, finely grind the edges around, round the edges and rounded corners and polish, then put it into the tempering furnace, and the heating time in the tempering furnace is 380 -450 seconds, spray the prepared salt solution to the glass surface at the same time, after the heating is completed, the glass enters the cooling section for rapid cooling, and the surface compressive stress value (MPa) of the glass is measured. See Table 1 for detailed process parameters.

Abstract

The invention relates to a making process and method of a single piece of Cs-K fireproof glass, implemented by simultaneously making physical and chemical toughening in a horizontal toughening furnace, where the chemical toughening is implemented by hot-spraying a salt solution with specific components. The made product has surface stress not less than 140 MPa and not greater than 180 MPa and advantageous fire-proofing function, and overcomes the defects of grout fireproof glass in bad weatherability, easy foaming under ultraviolet irradiation, low strength, and unability of being used to outer walls of buildings.

Description

technical field [0001] The invention relates to a manufacturing process and method of a single piece of fireproof glass, belonging to the field of deep processing of flat glass. Background technique [0002] According to the definition and classification of the National Standard of the People's Republic of China "Safety Glass for Buildings - Fireproof Glass" (GB15763.1-2001), fireproof glass is divided into single piece fireproof glass and composite fireproof glass. Monolithic fire-resistant glass (DFB) is a special glass composed of single-layer glass and meeting the requirements of the corresponding fire-resistant class. According to the fire resistance performance, it is divided into three categories: A, B and C. Among them, Class C fire-resistant glass is fire-resistant glass that meets the requirements of fire-resistant integrity. [0003] At present, there are mainly two types of single-piece fireproof glass at home and abroad: [0004] 1. Borosilicate glass: The gl...
