What happens when the binder reaches the primary pump? How does a heat treater avoid binder condensing?
In this Heat Treat Today Technical Tuesday, we are featuring a Best of the Web to learn about what happens to binder residue in vacuum furnaces when it is pumped up with process gas. This is the final segment of a four article series on the vacuum sintering process. To read the previous three articles, visit TAV Vacuum Furnaces for the details.
An excerpt: "As regards temperature, a quite natural solution would be to lower the temperature of the captured material. However, it is too costly to go below the values typically reached by industrial chillers. Instead it is easier to change to rotary pumps that work at higher temperatures, not least because these pumps are usually inexpensive. In fact when intending to use a vacuum system without being familiar with the problems of sintering, people tend to use high-performance, high final vacuum level pumps. To obtain this however, it is important..."
