Usage And Application: PVPK15,PVPK17, PVPK18, PVPK30 – The Pore-Forming Agent for Ultrafiltration Membranes in the Water Treatment Industry
In the water treatment industry, Polyvinylpyrrolidone (PVP) is extensively utilized as a pore-forming agent for ultrafiltration membranes due to its superior properties. PVP effectively controls the size and distribution of membrane pores, significantly enhancing the permeability of the membrane. Moreover, PVP increases the pore density and improves the hydrophilicity of the membrane surface, which are crucial for improving the efficiency of water treatment.
Ultrafiltration membrane manufacturers typically select the K15, K17, K18, and K30 grades of PVP for its narrow molecular weight distribution and excellent pore-forming effect. The PVPK15, PVPK17, PVPK18, and PVPK30 grades of PVP provide a uniform and consistent pore structure during the membrane-making process, which is essential for ensuring the filtration performance and stability of the ultrafiltration membrane
As a pore-forming agent for microfiltration, nanofiltration, or ultrafiltration PVDF/PSF/PES membranes, it can effectively control the size and distribution of membrane pore diameters, increase membrane pore density, improve membrane permeability, enhance the hydrophilicity of the membrane surface, and enhance the membrane’s anti-fouling capability.
PVP K85 is mainly used in the hollow fiber membrane of artificial kidney hemodialysis, serving as a pore-forming agent and preventing blood and plasma coagulation.
