Manufacturing method of waving type optical glass with low stripe bubble rate

Abstract

The invention discloses a manufacturing method of waving type optical glass with a low stripe bubble rate, and belongs to the field of optical glass; according to the manufacturing method of the waving type optical glass with the low stripe bubble rate, an isolation expansion strip layer is inflated; molten materials can be separated from the inner wall of a waving isolation container; compared with the prior art, the condition that impurities are doped into the molten material due to corrosion of a thermal insulation material on the waving isolation container is effectively avoided; the occurrence rate of stripes on the formed optical glass is effectively avoided; the product quality is improved, meanwhile, the waving gas strips are expanded into strips; inflation and deflation are controlled, so the strip-shaped waving gas strips are dynamic with constant ups and downs; and meanwhile, due to separation of the material and the waving separation container, the separation type stirringis always carried out in the smelting process, so that bubbles in the smelting process are effectively released, the bubble rate of the optical glass finished product is reduced, and the quality of the optical glass is further improved.

Description

technical field [0001] The invention relates to the field of optical glass, more specifically, to a dancing optical glass manufacturing method with low striae bubble rate. Background technique [0002] Glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. Optical glass in the narrow sense refers to colorless optical glass; optical glass in the broad sense also includes colored optical glass, laser glass, quartz optical glass, anti-radiation glass, ultraviolet and infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optical glass and photochromic Glass.

Problems solved by technology

[0004] In the prior art, during the production of optical glass, due to the smelting process, the heat-resistant material is corroded at high temperature, which will produce certain impurities. At the same time, the operation of stirring during smelting causes the impurities to diffuse in a large range in the smelted material. , resulting in streaks in the finished optical glass, affecting the quality. In order to reduce the distribution range of the streaks, the stirring during the smelting process cannot be carried out all the time. It needs short-term stirring in batches to reduce the diffusion of impurities. However, short-time stirring cannot Effectively remove the air bubbles in the smelting material, resulting in a large amount of air bubbles in the finished product, which affects the quality of the finished optical glass
