Abstract

The invention discloses a preparation technology of a Low-e bent laminated glass. The technology includes the steps of: a. employing a horizontal double-straight edge machine to conduct edging on Low-e glass substrates through a synchronous belt, then conducting cleaning in a cleaning machine; b. placing the cleaned glass horizontally on a roller way, sending the glass into a convection toughening furnace by the roller way and carrying out one-stage heating treatment; c. taking the heat treated glass out of the furnace and sending it into a bent wind grid, and letting the glass bend along with the bending of the conveying roller way and the wind grid by virtue of self weight; d. laminating the cleaned two or more bent steel glass in a dust-free airtight lamination chamber; e. reheating the bent glass obtained in step d and slowly prepressing the bent glass through a bent glass roller press to remove air; and f. putting the bent glass of step e into an autoclave to conduct heating and pressurization so as to remove residual air. The bent glass process is simple, the produced glass has high tensile strength, bending strength and impact strength and beautiful appearance, and is transparent.

Description

technical field [0001] The invention relates to a manufacturing process of tempered glass, in particular to a manufacturing process of Low-e curved laminated glass. Background technique [0002] Laminated glass is laminated glass, which is sandwiched between two or more pieces of glass with one or more layers of organic polymer intermediate film. After special high-temperature preheating (or vacuuming) and high-temperature and high-pressure processing, the glass Composite glass products that are permanently bonded to the interlayer. Common laminated glass interlayers include PVB, SGP, EVA, PU, ​​etc. Laminated glass is a kind of safety glass with good impact resistance, penetration resistance, safety, noise reduction, UV protection, etc. With the development of the times, laminated glass has been widely used in almost all occasions where glass is used, such as building doors and windows, lighting ceilings, skylights, suspended ceilings, large-area glass walls, glass furnit...
