CONSTRUCTION TECHNOLOGY DIV. INVESTMENT HOLDINGS GROUP

Represents Mondomix Holland multicomponent equipment for processing multicomponent reactive resin systems with various types of metering devices commensurate with viscosity characteristics, accuracy requirements, and matched to meet overall process control/demands of the production line. Metering/ratio accuracy is controlled by mass-flow meters with computer-monitored interlock responsive to the instant demand of the production line. Temperature control of all components is available, including the mixer rotor, and stator. A special application of the mixing head design permits the mechanical encapsulation of gases providing foam cell-size control down to the submicron range (in lieu of chemical blowing reagents). Upon dispensing this mechanically encapsulated glass blend, the blend emerges pre-expanded and may be titled "frothing equipment."

With the required elimination of CFCs for urethane foaming operations and the potential substitution of HCFCs, the difference in the resultant thermal insulation properties can be eliminated by producing submicron-sized cells using the special Mondomix mixing heads.
