摘要: A method of making glass through a glass ribbon forming process in which a glass ribbon is drawn from a root point to an exit point is provided. The method comprises the steps of: (I) cooling the glass ribbon at a first cooling rate from an initial temperature to a process start temperature, the initial temperature corresponding to a temperature at the root point; (II) cooling the glass ribbon at a second cooling rate from the process start temperature to a process end temperature; and (III) cooling the glass ribbon at a third cooling rate from the process end temperature to an exit temperature, the exit temperature corresponding to a temperature at the exit point, wherein an average of the second cooling rate is lower than an average of the first cooling rate and an average of the third cooling rate.

摘要: Computer-implemented methods and apparatus are provided for predicting/estimating (i) a non-equilibrium viscosity for at least one given time point in a given temperature profile for a given glass composition, (ii) at least one temperature profile that will provide a given non-equilibrium viscosity for a given glass composition, or (iii) at least one glass composition that will provide a given non-equilibrium viscosity for a given time point in a given temperature profile. The methods and apparatus can be used to predict/estimate stress relaxation in a glass article during forming as well as compaction, stress relaxation, and/or thermal sag or thermal creep of a glass article when the article is subjected to one or more post-forming thermal treatments.
