Does Vaseline clog ion exchange membranes?

Vaseline does not clog the ion exchange membrane. This is mainly because our petroleum jelly is a grease, and its density is relatively low, so it will float on top of the water and will not block the underwater ion exchange membrane at all.

Ion exchange membrane is a polymer membrane containing ionic groups that selectively permeabilizes ions in solution. Because it is generally used in applications to select its ion permeability, it is also called ion selective permeability membrane. 1950 w

Zhu Da first synthesized an ion exchange membrane. It was first successfully used in the electrodialysis desalination process in 1956.

Ion exchange membranes are thin films made of polymer materials with ion exchange properties (there are also inorganic ion exchange strands, but their use is not yet common). It is similar to ion exchange resins in that they connect an active group on the polymer backbone, but the mechanism, mode and effect are different. There are many types of ion exchange membranes on the market today, and there is no uniform classification method.

Generally, according to the macrostructure of the membrane, it is divided into three categories:

1.Heterogeneous ion exchange membrane is made of powdered ion exchange resin and binder, mixing, pulling tab, and net hot pressing. The resin is dispersed in the binder, so its chemical structure is inhomogeneous.

2.Homogeneous Ion Exchange Membranes Homogeneous ion exchange membranes are made by introducing active groups into an inert support. It has no out-of-phase structure and is homogeneous in itself.

Its chemical structure is uniform, the pores are small, the membrane resistance is small, it is not easy to leak, the electrochemical performance is excellent, and it is widely used in production. But the production is complex and the mechanical strength is low.

3.Semi-homogeneous ion exchange membranes are also made by introducing active groups into polymer supports. However, the two do not form a chemical bond, and their performance is between homogeneous ion exchange membranes and heterogeneous ion exchange membranes.

It can't be blocked, but the skincare product doesn't solidify.
