The usefulness of magnetic rods

Magnetic rods in contact with the fluid process using internal magnetic energy will be part of an irreversible loss, loss exceeds the initial intensity of 30% or surface coating of iron, stainless steel pipe rupture when worn, then the need to replace the magnet bars, and not allow leakage magnet magnetic rods continue to work, magnets are generally more brittle surfaces coated with some oil, the environmental pollution is relatively large. magnetic filter bar domestic producers generally magnetic wand to work under heavy load 1 - 2 years, seven under light load - 8 years. Mainly used in plastics, food, environmental protection, filtration, chemicals, power, building materials, pottery, medicine, powder, mining, coal and other industries
