Description

Technical Field

[0001] The utility model belongs to the technical field of experimental instruments, and in particular relates to a magnetic stirring device. Background Art

[0002] Carbon nanotube materials have poor compatibility in the pipe matrix resin and cannot effectively form a barrier layer, which easily leads to the corrosion resistance of the molded composite PP-R pipe being difficult to achieve as expected. However, studies have found that a layer of carbon nanotubes with magnetic nanoparticles / hydroxyapatite uniformly dispersed on the outer surface of the matrix PP-R pipe can form a dense and orderly polyamide anti-corrosion barrier layer, thereby avoiding the defect of unsatisfactory anti-corrosion effect caused by uneven dispersion of functional phases in the pipe product. In the process of developing this kind of corrosion-resistant PP-R water supply pipe, it is necessary to mix solid and liquid raw materials such as ferroferric oxide magnetic nanoparticles, hydroxyapatite inorganic particles and silane coupling agents by magnetic stirring, so that the modified carbon nanotubes can self-assemble with the magnetic nanoparticles / hydroxyapatite by liquid phase deposition.

[0003] However, in the prior art, when mixing relatively viscous or large-volume solutions, it is not easy for the magnetic stirring device to stir the solution evenly from the middle to the upper part, and it is difficult to conveniently clean the magnetic stirring device after stirring. Therefore, a magnetic stirring device is proposed. Utility Model Content
