PTFE pall ring is developed on the basis of the PTFE raschig ring, PTFE pall ring is to open one or two layers of rectangular holes in the sidewall,and the base material of the holes is not out of the sidewall but forms inward bending of blade.The same size of Pall ring and Raschig ring have the same surface area and porosity,but the pall ring’s holes on its sidewall can flow gas-liquid so that the ring inner surface will be took full advantage.Than Raschig ring,Pall ring has not only greater production capacity and lower pressure drop ,but also the high separation efficiency,meanwhile the phenomenon of channeling is also greatly reduced.
Features:
l PTFE pall ring has high temperature resistance:operating temperature is up to +160°C.
l PTFE pall ring has high separation rates:
l PTFE pasll ring has low temperature resistance:has good mechanical toughness.even if the temperature drops to -196°C,but also to maintain the elongation rate of 5%.
l PTFE pall ring has corrosion-resistant:showed inert to most of chemical and solvents,resistanting acid and alkali,water and various organic solvents.
l PTFE pall ring has weather resistance:has the best aging life in plastic.
l No poison:non-toxic to biological.
