Background
With the development of technology and molding technology, after various technological enterprises finally atomize metals into various metal powders with very small particle sizes through a series of technologies, downstream enterprises respectively apply the fine metal powders to the following purposes:
1. Adding organic binder into metal powder to prepare metal paste, printing the metal paste on the surface of a ceramic substrate through a silk screen template to prepare a thick film circuit board product, sending the printed ceramic substrate green compact into an atmosphere furnace to perform low-temperature glue discharge (organic binder discharge) and subsequently performing high-temperature sintering on the thick film circuit board.
2. After various resin binders are added into metal powder, mixing and fusing are carried out uniformly, the mixture is injected into a mould by an injection molding machine to be molded, and then the mixture is put into a furnace, and the organic binders are removed by degreasing and removing glue at a low temperature before 600 ℃ and then are subjected to high-temperature vacuumizing sintering.
Because the oxidation temperature of the titanium metal material is generally about 400-500 ℃, the oxidation temperature depends on the content of oxygen gas and the oxidation time factors. If the titanium metal material is subjected to peroxidation in the air atmosphere due to high oxygen content at high temperature, the titanium metal material cannot be completely reduced by hydrogen when the inside of the part is oxidized due to the peroxidation. Therefore, the oxygen content in the furnace is controlled in the glue discharging process to become the technical problem of glue discharging.
