Abstract
A mixing method provided by the invention comprises steps of melting a solid-state polymer raw material into a flowable molten raw material fluid to flow into a mixing space at a first volume flow rate, when the raw material fluid entering the mixing space, introducing a foaming agent in a fluid form into the mixing space simultaneously or at a different time, mixing the foaming agent with the molten raw material fluid into a mixture in the mixing space, circulating the mixture in the mixing space at a second volume flow rate, and causing the second volume flow rate greater than the first volume flow rate.

A mixing method comprising following steps of:
- melting a solid-state polymer raw material into a flowable molten raw material fluid to flow into a mixing space at a first volume flow rate;
- introducing a foaming agent in a fluid form into the mixing space;
- and
- mixing the foaming agent with the molten raw material fluid into a mixture in the mixing space, and circulating the mixture in the mixing space at a second volume flow rate;
- wherein the second volume flow rate is greater than the first volume flow rate.
A mixing system comprising:
- a first flow path allowing a fluid to flow at a first volume flow rate;
- and
- a second flow path allowing the fluid to flow at a second volume flow rate, the second volume flow rate being made to be greater than the first volume flow rate;
- a solid-state polymer raw material being melted into a flowable molten raw material fluid in the first flow path;
- and
- the molten raw material fluid leaving the first flow path and entering the second flow path at the first volume flow rate, a foaming agent fluid being introduced into the second flow path simultaneously or at a different time, so that the molten raw material fluid and the foaming agent being mixed to form a mixture, and the mixture being made to flow in the second flow path at the second volume flow rate.
