Q

Reaction Rate Fluctuation

A

This problem is a typical manifestation of reaction rate fluctuation in the RIM process; the core of the solution lies in ensuring the precise ratio and full mixing of the two components, while controlling the reaction temperature and curing conditions within the optimal window. It is recommended...

Q

Mixing Head Blockage

A

RIM mixing quality is the first element determining part consistency. The core control points are: the impingement mixing Reynolds number of the mixing head (to ensure turbulent mixing), the viscosity matching of the two components (to reduce viscosity difference), the accuracy of the metering pu...
