A kind of non-oxide sulfur-based glass leakage production device and production method thereof

Abstract

The invention discloses a leakage-injection production device for non-oxide chalcogenide glass and a production method thereof, belongs to the technical field of infrared optical glass manufacture and mainly solves the problems of the conventional devices that the production efficiency is low and the production cost is relatively high. The leakage-injection production device is mainly characterized in that the inner chamber of a furnace main body is divided into a smelting chamber, a forming chamber and an atmosphere control chamber by partition boards; a furnace door is formed in the front face of each of the smelting chamber and the forming chamber; a quartz crucible, a quartz cover plate, a crucible heating device, a stirring device, a pull rod and a material leakage pipe are arranged in the smelting chamber, a ball body is arranged at the lower end of the pull rod, and the upper end of the pull rod is connected with a support device; a forming die, a forming platform and a die heating device are arranged in the forming chamber; and an exhaust tube and an aeration tube are arranged in the atmosphere control chamber, and a smelting vent hole and a forming chamber vent hole are respectively formed in the partition boards adjacent to the smelting chamber and the forming chamber. The leakage-injection production device has the characteristics of simple structure, convenience in operation, reliable performance, high production efficiency and use safety and is mainly used for carrying out leakage injection of the non-oxide chalcogenide glass.

Description

technical field [0001] The invention belongs to the technical field of infrared optical glass manufacture. It relates to a non-oxide chalcogenide glass leakage injection production device and a production method thereof. Background technique [0002] With the development of society, the application of skynet monitoring, security, automobile and infrared thermal imaging system is more and more extensive. Caliber demand direction. Compared with oxide glass, non-oxide chalcogenide glass is produced in a completely different way. In particular, it cannot be produced in air, nor can it be stirred by traditional stirring devices. At present, the production of non-oxide chalcogenide glass usually uses a swing furnace, such as figure 1 As shown, the non-oxide chalcogenide glass batch is filled into a special container, that is, an ampoule, which is then vacuum-packed and placed in a furnace. Raise the temperature of the furnace to 1000°C and make the furnace body swing back and ...

AI Technical Summary

Problems solved by technology

However, the current commercially available ampoules cannot meet the requirements, which seriously restricts the quality, batch size and production cost of non-oxide chalcogenide glass.

Although the pouring method can be used to solve the above problems, due to the inevitable pouring streaks during pouring, there will be streaks inside the glass, which will affect the imaging quality of the final product
