The new generation of lithium aluminum silicate glass has gradually become the main structural material of aerospace transparent. Due to high elastic modulus and excellent ion exchange capacity, it has excellent mechanical performance after chemically strengthened, which can well meet the lightweight and high strength requirements of aerospace transparent. In this paper, 1.8 mm thick lithium aluminum silicate glass was taken as the research object, and the impact resistance of chemically strengthened glass was studied. The influence of center tension on the impact resistance is discussed by theoretical calculation based on the stress profile. Glass samples were prepared by different chemically strengthened processes for the falling ball impact testing. The results show that the impact resistance is excellent when the compressive stress is approximately 930 MPa and the depth of layer is 130～160 μm, and the 1.8 mm glass has good mechanics performance.

The technology of vitrification products by using fly ash from domestic waste incineration as raw material is studied. When the addition amount of fly ash is 40%, the samples are all in a good glassy state, and have excellent acid, water and alkali resistance. According to the latest national standard “Technical Specification for Solid Waste Vitrification Products”, the test results show that the obtained samples are far better than the technical requirements, especially the content of leached hazardous substances, most of which are in an undetected state. It eliminates obstacles for resource utilization of fly ash , which is a high-value utilization of vitrification products made from fly ash.

The microstructure and mechanical properties of a 360 MPa grade high-strength cold-rolled double-sided enamel were studied by optical microscope, scanning electron microscope and tensile tester. The fish-scaling resistance of the experimental steel was evaluated by hydrogen penetration experiment, and the wet and electrostatic dry applying experiments were also performed in the laboratory. The results show that the microstructure of the experimental steel before and after enameling is ferrite, the ferrite changes from flat to equiaxed and the average grain size increases from 5.47 μm to 7.07 μm. The precipitates of the experimental steel before and after enameling are mainly composed of C, S, Mn and Ti, and the amount of precipitates in the grain decreases obviously after enamel. Before enameling, the yield strength, tensile strength and elongation of the experimental steel are 382 MPa, 469 MPa and 34.5%, respectively. After enameling, the yield strength reduced to 355 MPa, the tensile strength reduced to 405 MPa, and the elongation increased to 38%. The decrease of the strength is caused by the increase of the average grain size of ferrite and the decrease of the density of the second phase precipitates. The hydrogen penetration time of the experimental steel is 9.68 min. After double-sided enamel by wet and electrostatic dry methods, there is no fish-scaling defect indicating good adherence performance.

In order to further improve the yield and quality of float glass raw sheet, the influence of damper block with and without diversion groocve on glass defects in float glass production process was compared and analyzed. It is found that damper block without diversion groove contribute to glass defects reducing in production.

The structure of blowhead is introduced, followed by the discussion of the working mechanism and function of blowing and exhausting. The discussion of the principles of cooling in hot bottles is focused particularly. Then the movement of blowhead and its relation to its structure are studied. Finally, the potential defects of the blowhead are described.

As a basic part of LCD/LED display process, photoelectric display glass substrate plays an extremely important role. As a spacer between glass substrates, the finished spacer paper is indispensable in the packaging process of glass substrates. It is necessary to further improve and optimize the current carton device to solve the problems of wear and tear during carton movement, static electricity of finished paper spacing and multi-paper, so as to meet the needs of production and quality requirements.

Liquid crystal display plate has very high requirements for the quality of substrate glass and the number of internal defects in glass. As one of the main defects of liquid crystal glass substrate products, bubble defects have different shapes and production mechanisms. According to the classification of common bubble defects in liquid crystal glass substrate, the causes of different bubble defects were analyzed, and the corresponding countermeasures were put forward.

The properties of glass-lined layer are related to the chemical composition, melting process, firing process, uniformity of layer thickness, and defect control. The service life of glass-lined equipment depends on its performance. Heterochromatic dots is one of the common defects in enamel coating. There are many reasons for heterochromatic spots, which need to be analyzed in order to determine a reasonable solution.
