Device and method for laboratory glass sample melting

Abstract

The invention belongs to the field of glass manufacturing in the industry of panel display and relates to a device and method for laboratory glass sample melting. The method includes: pouring a weighed batch mixture into a sample melting crucible, putting the sample melting crucible on a placement table which is capable of moving up and down along with a lifting table, and stirring molten glass with a stirring rod in a sample melting process, wherein the sample melting crucible is in a two-layer structure with inner and outer layers, the inner layer is made of a precious metal platinum or platinum rhodium material, and the outer layer is made of a high-temperature-resistant ceramic fiber cotton. In addition, a novel sample melting temperature process is designed. By implementation of the method, complete melting of the glass batch mixture can be guaranteed while problems of component nonuniformity and high viscosity difference in laboratory crucible sample melting can be solved, high-quality glass samples are obtained through laboratory melting, and accuracy in molten sample testing and analysis can be improved beneficially.

Description

technical field [0001] The invention relates to a method and device for laboratory glass melting, which is suitable for melting various glass products used in the flat panel display industry in the laboratory. Background technique [0002] With the continuous development of flat panel display device technology, the glass (ITO conductive glass, protective glass, glass substrate) used in the flat panel display industry is not only in increasing demand, but also in higher performance requirements. In particular, the glass substrate is one of the key basic materials of the flat panel display industry, and it is also the most used glass. To meet the market's demand for high-performance glass, it is necessary to develop a new material recipe through continuous melting, analysis, and testing in the laboratory, and provide process characteristics and process parameters for key materials and equipment design for the industrialization of the material recipe. However, due to the high ...

AI Technical Summary

Problems solved by technology

A stirring device is added to the melting sample in the laboratory. Compared with the melting sample without this device in the past laboratory, it solves the phenomenon that the viscosity difference between the upper and lower sides of the melting sample in the laboratory crucible is too large and the composition is uneven, so that the melting in the laboratory is high. High-quality glass samples are conducive to improving the accuracy of test and analysis of molten samples
