Description

A rapid cooling device for a vacuum pump

technical field

The utility model relates to the technical field of resin production, in particular to a rapid cooling device for a vacuum pump.

Background technique

Resin usually refers to an organic polymer that softens or melts after being heated, has a tendency to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad definition, any polymer compound that can be used as a raw material for plastic products is called a resin.

After normal pressure esterification to produce polyester with a low degree of polymerization, it is necessary to further increase the degree of polymerization to reduce the acid value. This section requires the operator to try to reduce the pressure once to the required index range and avoid repeated pressure reduction. In the initial stage of vacuum Slowly increase the vacuum degree to avoid material overflowing into the tower column. Before decompression, keep the temperature of the kettle not to drop too much, otherwise the vacuum time will be greatly extended.
