Ferrofluid from the microscopic composition of ferromagnetic nanoparticles, usually from magnetite, hematite or other mixtures containing iron. A typical size of these nanoparticles 10 nanometers; in this small enough scale, heat agitation can make them in a carrier fluid which is uniformly dispersed, long magnet wholesale supply, so that their overall response to the magnetic fluid acts . This mode of action is similar along the magnetic ions and salt solutions (such as copper sulfate or manganese chloride solution) which makes the solution paramagnetic. The real ferrofluid is stable. This means that the solid particles agglomerate or phase separation even in a strong magnetic field which does not occur. However, after a certain period of time the surfactant (years) decomposition will occur, resulting in the final nanoparticles aggregated and separated from the magnetic strip of quality assurance, and thus the magnetic fluid no longer acts reaction. Magneto-rheological fluid (MRF) refers to similar ferrofluid (FF) and a magnetic field in the presence of solidified liquid. Magneto-rheological fluid containing particulate microns, the size composition of ferrofluid particles than 1-3 orders of magnitude higher. 11 magnet operation What precautions? Magnets during use should ensure workplace clean, long magnet price quotes, otherwise easily absorbed iron and other small particles affect the use of magnetic; NdFeB material is characterized by hard and brittle, and its suction up to 600 times its own weight more easily pull collision. Procedure for small size should be taken to avoid bump damage, but also to pay attention to the large size of the personal safety and protection. What is the reason 12 of the coating from the skin and the reason is the rust? Qualified electroplating products, under normal circumstances, should not be electroplated coating rust appears. In too wet, poor air circulation, temperature change is large, even the salt spray test qualified products long-term storage in harsh environments may produce rust. When plating products stored in harsh environments environment, long magnet, the base layer is further reacted with condensation of water will cause the binding force base layer and the coating is reduced, can also cause serious local base powder, and then naturally from the skin. Plating product should not be placed in long-term high humidity place, it should be placed in a cool, dry place.
