Plastic super mini ring, also called as plastic flat ring, is like the cascade ring canceled the flange ring ladder. As this special design, the bulk density of random packing is improved. Plastic super mini ring has a small ratio of height to diameter, about 1:3 and it has reasonable passage structure, low pressure drop, high flux, and excellent treating. Handling ability and mass transfer have been improved.
Plastic suer mini ring is especially suitable for relative flow movement of liquid-liquid phase and lessens agglomeration of dispersed droplet cluster.
Plastic super mini ring is made of anti-chemical corrosion materials, such as: PE, PP, PVC, CPVC, RPP, PVDF, etc.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
High mechanical strength
Large handling capacity
High mass transfer and high flux and low pressure drop
Uniform gas and liquid distribution
With high processing capacity and mass transfer performance, plastic super mini ring is widely used in liquid-liquid extraction, gas-liquid mass transfer, vacuum distillation, thermal sensitive material distillation, decomposable plant material distillation, polymerization material distillation, carbonization material distillation, etc.
