Abstract

The invention relates to a manufacturing method for magnetic pearl cores and belongs to the technical field of pearl cultivation. The method comprises the following steps that magnetic powder and pigment are mixed to be uniform on the melting condition by adopting non-toxic plastics as a medium to manufacture a base material, the base material is used for producing original pearl cores by adopting an injection molding method, the surfaces of the original pear cores are coated with a layer of film coating pearl cores made of biological compatible materials, finally, the film coating pearl cores are magnetized so that the film coating pearl cores have magnetism, and the magnetic pearl cores for producing magnetic healthcare pearls can be made; the method can industrially produce a large number of magnetic pearl cores, efficiency is high, and the cost is low; the surfaces of the pearl cores have the good biological compatibility material treatment, the rejection effect of shell bodies on pearl cores is lowered, and the core reserving efficiency is high.

Description

technical field [0001] The invention relates to the preparation of magnetic bead cores, in particular to a method for producing magnetic bead cores, and belongs to the technical field of pearl cultivation. Background technique [0002] my country's pearl industry has a long history, but in recent years, the economic benefits of pearl cultivation have been declining. One of the reasons is that the current pearl has a single function and only has ornamental value, which restricts the consumer market and price of pearls. As we all know, when the magnetic field acts on the human body, it will produce six major effects: promoting blood circulation and improving microcirculation; regulating blood pressure and reducing blood viscosity; reducing inflammation and analgesia; improving the body's immunity and delaying aging; regulating the function of the nervous system and eliminating fatigue ; detoxification. When the human body wears magnetic pearls, it can achieve the dual effects...
