Reaction injection machine of large flow-rate IntroductionLow-pressure reaction injection machine of large flowrate developed on our own is a kind of low-pressure injection equipment with the throughput as much as 6, 000 gms/sec, which is suitable for making large block-type flexible, half-rigid, and rigid foam products and is widely used in the production of automobiles, building and industries needing insulating materials. Using such machine to produce large foam plastic is accurate in metering, uniform in foaming and stable in quality and can completely substitute manual mixing and foaming method, greatly increasing the working efficiency.Mixing ratioA:B=2.5:1A:B=1:1Or in accordance with technical requirementVolume of loading tank (L)71000510007 scales in total, see throughput list for detailsVolume of loading tank (L)403004030040120150220300Revolution of mixing head (rpm)3500-45003500-4500Program-controlled points1212Viscosity requirement (CPS)20002000Temperature adjusting range0-500-50Total powerkw9189186 kw for heatingForm of mixing head assemblyCrane or Overhead travellingExternal dimensionsmLength×Width×Height 3.0×1.5×2.34.4×1.8×3.0 (for tank of 150 L)
