Solvent Purification in Gel-Spinning Technology for UHMWPE Fibers

A method for cleaning Vaseline oil, the solvent for UHMWPE in gel-spinning technology, of finely disperse particulates of paraffins with chain lengths greater than C 16 H 34 that are formed mainly by mechanical and thermal oxidative destruction during dissolution of UHMWPE is considered. The solvent...

Description
Summary:A method for cleaning Vaseline oil, the solvent for UHMWPE in gel-spinning technology, of finely disperse particulates of paraffins with chain lengths greater than C 16 H 34 that are formed mainly by mechanical and thermal oxidative destruction during dissolution of UHMWPE is considered. The solvent should be cleaned of destruction products by medium speed vacuum filtration through a filtering diaphragm combining a layer of URSA nonwoven material and two layers of filter paper to enable it to be reused.
