摘要:
A substantially-isolated/controlled, limited-volume, gas-filled space (e.g., 113b) is formed over at least one free (open) surface of flowing molten glass in a manufacturing line used to produce glass sheets (137), e.g., a manufacturing line employing the fusion process to produce glass sheets suitable for use as substrates for liquid crystal displays. At least a portion of the space comprises a platinum-group metal, e.g., a platinum-rhodium alloy, which can serve as a source of platinum-group condensate defects. The use of the substantially-isolated/controlled, limited-volume, gas-filled space substantially reduces the level of such platinum-group condensate defects in the glass sheets, e.g., by more than 50%.
摘要:
A glass sampling apparatus and a method for using the glass sampling apparatus to obtain a glass sample from molten glass within a glass melting vessel are described herein. In one embodiment, the glass sampling apparatus includes: (a) a sampling tube having a first end and a second end, where the second end is used to obtain the glass sample from the molten glass in the glass melting vessel; (b) a first valve; (c) a vacuum device; and (d) a tube network that couples the first end of the sampling tube to both the first valve and the vacuum device.

摘要:
A fiber-based gasket, a glass manufacturing system, and a method are described herein for reducing thermal cell induced blisters. In one embodiment, the fiber-based gasket is placed in a connection between a first glass manufacturing device (e.g., capsule surrounding a downcomer) and a second glass manufacturing device (e.g., fusion draw machine surrounding an inlet). The fiber-based gasket has a density and compression which results in a gas permeation rate per unit surface area that is less than 22.5 ml/min/cm2 to reduce thermal cell induced blistering within the first glass manufacturing device and the second glass manufacturing device.
