Method for further processing thin glass and thin glass produced by such method
Abstract:
A method for processing a thin glass is provided. The thin glass is subjected to a tensile stress σapp smaller than 1.15 · Min ⁡ ( σ _ a - Δ a ⁢ 0.4 · ( 1 - ln ⁡ ( A ref A App ⁢ Φ ) ) , ⁢ σ _ e - Δ e ⁢ 0.4 · ( 1 - ln ⁡ ( L ref L App ⁢ Φ ) ) ) , wherein σa is a mean value of tensile stress at break for fractures in a surface of samples of the thin glass under bending stress, wherein σa is a mean value of tensile stress at break for fractures emanating from an edge of the samples, wherein Lref is an edge length and Aref is a surface area of the samples, wherein Δe and Δa denote standard deviations of the mean values σe and σa, respectively, and wherein Aapp is a surface area of the thin glass, Lapp is a summated edge length of opposite edges of the thin glass, and Φ is a predefined maximum fracture rate within a period of time of at least half a year.
