Description
Technical Field

Background
The substrate glass is a key material in the flat panel display industry, and the overflow method is a main stream production process for producing the substrate glass, and has the advantages of high surface smoothness and high flatness. With the development of the technology of the liquid crystal display panel of the high generation, the quality of the substrate glass, especially the flatness, the warping and the stress are required to be higher. The overflow brick is one of the core components of the forming device, and the glass liquid flows into the overflow groove, overflows from two sides of the overflow brick and finally merges with the brick tip to form a glass plate. The overflow brick is closely related to the thickness uniformity, flatness and other qualities of the glass substrate.
At present, the 8.5-generation liquid crystal panel line at home and abroad has become the main stream of the display industry, and the length of an overflow brick adopted by the corresponding 8.5-generation substrate glass production line reaches more than 3100mm, and the overflow brick is generally installed in a muffle furnace by adopting two-end supports. In actual production, the overflow brick works under the environment of 1100-1300 ℃ and bears the weight of the overflow brick and glass liquid, and creep deformation can occur slowly. This deformation is embodied by the downward deflection of the middle portion of the overflow brick. The generation of the middle deflection can affect the thickness and flatness quality of the glass plate. When deflection deformation is accumulated to a certain degree, qualified glass plates cannot be produced finally. Therefore, the method has important guiding significance for measuring and monitoring the creep deformation of the overflow brick and predicting the service life of the overflow brick, and has important practical significance for reasonably carrying out resource allocation and capacity planning on companies and guaranteeing the continuous supply capacity of downstream manufacturers.
Since the overflow brick works in a high-temperature environment for a long time, the whole body is wrapped by glass liquid, and the creep deformation of the overflow brick is difficult to measure and monitor.
