PURPOSE:To obtain the matrix material of a magnetic filter capable of maintaining its performance for a long period in a strongly acidic or strongly alkaline fluid by coating an org. high molecular compd. having excellent corrosion resistance on a base material consisting of a ferromagnetic substance. CONSTITUTION:An org. high molecular compd. consisting of a synthetic high molecular compd. such as melamine or acrylic resin or a natural org. high molecular compd. such as rubber and starch is coated on the base material consisting of a ferromagnetic substance such as a crystalline iron alloy to obtain the matrix material of a magnetic filter. Namely, the matrix material of a magnetic filter is made from alloy fibers or beads obtained by thinly coating the org. high molecular compd. on a ferromagnetic alloy. The coating is carried out by dip coating, spray coating, etc. Moreover, air drying, drying by heating, and curing by light can be optionally selected in accordance with the kinds of the coating materials in drying and curing the coat. |
