Preparation method for anti-corrosion magnetic pump fluid part material

Abstract

The invention belongs to the technical field of processing of a magnetic pump material and specifically relates to a preparation method for an anti-corrosion magnetic pump fluid part material. The method comprises the following steps: treating ytterbium oxide and lutetium oxide with an organic solution containing a titanate coupling reagent; utilizing polyisobutene and ferrocene to modify the ytterbium oxide and lutetium oxide; and uniformly dispersing the treated rare earth in a polytetrafluoroethylene material, thereby maintaining nanometer characteristics of the particles. The structure of the polytetrafluoroethylene material is refined and is easily processed and molded; and on the basis of the maintained excellent performance, the polytetrafluoroethylene material has higher structure stability and chemical stability under the working condition of changing pressure, so that the service life of the anti-corrosion magnetic pump fluid part material can be prolonged.

[0002] Corrosion-resistant magnetic pumps are widely used in petroleum, chemical, acid, alkali, smelting, rare earth, pesticides, dyes, medicine, paper, electroplating, electrolysis, pickling, radio, chemical foil, scientific research institutions, national defense industry and other production processes It is especially suitable for the transportation of flammable, explosive, volatile, toxic, strong acid and alkali, organic solvents and precious liquids. In order to ensure the corrosion resistance of the corrosion-resistant magnetic pump, the fluid part is usually selected Strong corrosive non-metallic materials, among which polytetrafluoroethylene is one of the main materials. Polytetrafluoroethylene is polymerized by tetrafluoroethylene to form a polymer compound, which has excellent chemical stability and has a small friction coefficient, It has the advantages of not absorbing water, etc. It is mainly used in various devices such as diaphragms, seals, and sealing friction pairs in pump valves. However, there are large linear expansion coefficients, poor dimensional stability, poor thermal conductivity, easy cold flow, and difficult molding during use. The disadvantages make it have defects during use. These defects limit the scope of use of PTFE. With the increase of flow and pressure and the deterioration of negative pressure conditions, it will seriously affect the normal operation of chemical pumps.
