The main purpose of magnetic rods is to remove iron filings in raw materials; to filter various fine metal powders and liquids, iron-containing impurities in semi-liquids and other magnetic materials, which are widely used in chemical, food, waste recycling, Black and other fields. The following is a brief introduction for you, hoping to bring you some help. A good magnetic rod should achieve uniform spatial distribution of magnetic induction lines, and the maximum magnetic induction intensity point distribution should be as large as possible to fill the entire magnetic rod, because the magnetic rod is generally placed in the moving product transmission line. Contains substances that are harmful to the environment, avoiding pollutants and the environment. The working environment of the magnetic rod determines that it must have certain corrosion resistance and high temperature resistance, and some occasions need a relatively strong magnetic induction strength. Different magnetic induction strengths can be obtained by using magnetically conductive sheets of different thicknesses. Choosing different magnets can determine the maximum of the magnetic rod
Magnetic induction strength and temperature resistance performance. Generally, if you want to achieve a surface magnetic induction strength above 10,000 Gauss on a conventional ∮25 magnetic rod, you need a high-performance model of NdFeB Magnetic steel. High temperature resistant magnetic rods generally choose samarium cobalt magnetic steel when the temperature exceeds 150 degrees. However, samarium cobalt is usually not selected for magnetic rods with relatively large diameters. After all, the price of samarium cobalt is very high, and the price of a magnetic rod reaches tens of thousands of yuan. The magnetic induction strength of the surface of the magnetic rod is directly proportional to the smallest particle size that can be adsorbed, but in the fields of batteries, pharmaceuticals and other small iron impurities can also have a great impact, so it is necessary to choose a magnet roller (∮110-∮220) ). Other areas can choose a lower one. In the process of using the magnetic rod in contact with the fluid, there will be some irreversible loss of the internal magnetic energy. The loss exceeds 30% of the original strength or the surface of the iron skin.
When the damage is broken, the magnetic rod needs to be replaced at this time, so that the magnetic rod that leaks out of the magnet can not continue to work. The magnet is generally relatively brittle, and the surface is also coated with some oil, which causes greater environmental pollution. Domestic magnetic rod manufacturers can generally use 1-2 years under heavy load and 7-8 years under light load. Mainly used in plastics, food, environmental protection, filtration, chemical, power, building materials, building ceramics, medicine, powder, mining, coal and other industries.
