| Popis: | International audience; Reaction Injection Moulding, RIM, is a technology for the production of plastic parts usingreactive in situ polymerization from the mixing of two or more liquid monomers. AlthoughRIM is a widely used process, nowadays there are no means to effectively control mixing.This work assesses a new control variable of mixing in RIM: the differential static pressurebetween the liquid monomers injectors. This control variable is related to the mechanicalproperties of injected RIM parts. The dynamics of the control variable is also assessed. Amodel is introduced to relate the control variable with the mixing conditions in RIM. |
