Rock wool glue spray foaming machine: inject two kinds of PU glue into the spray-head by metering pump, mixed in static mixing head and spray evenly on the up and down steel plate through damping hole,and then the glue will reflect and retrogradation.

Rock wool glue spray device is the core part of the whole production line. We adopt two- group glue system:1A, 2B, each group is controlled by measuring frequency converter, the system can change the out-put flow and mixture ratio. The working mode of the system is online mixture, the out-put A and B glue through the measurement unit, high-pressure atomize head, static state hybrid tube. The whole machine adopt HMI man-computer interface control, making the spray glue quantity in tandem with the main machine speed, animate the working process to ensure the constant of spray glue quantity.
