Production process of rubber magnet: in the formulation planning, the type, particle size and dosage of magnetic powder should be determined first. Next, the rubber type shall be determined according to the use requirements, for example, natural rubber shall be selected as the wear-resistant medicine. In the process of processing, the magnetization process that other products do not have needs to be added before or after vulcanization to give permanent magnetism to products. The advantages of magnetization before vulcanization are that the direction of external magnetic field is constant, and the rubber network is relatively smooth; the permeability of magnetization after vulcanization is poor, but the operation is more convenient. In short, each has its own advantages and disadvantages. Rubber magnetism --- the physical quantities used to characterize magnetism include magnetic induction strength, residual magnetic induction, magnetic energy product, etc. the magnetic induction strength is most commonly used, and its measurement unit is Gauss (GS). Generally, rubber magnetism is required to reach the range of 100-600gs.

 

Rubber magnet, also known as bonded permanent ferrite, is made of bonded ferrite magnetic powder, rubber or plastic and other materials by kneading, calendering or injection molding. Because of the high plasticity of the data itself, the finished products or semi-finished products can be cut, punched, cut lengthwise and mounted with other materials at will, and it is not easy to demagnetize, and it has good corrosion resistance, mainly divided into the same-sex rubber magnetic and the different-sex rubber magnetic. The differences are as follows:

 

1. Different magnetism: the same-sex rubber has weaker magnetism, while the opposite rubber has higher magnetic function.

 

2. The density and temperature of the same-sex rubber magnet are lower than that of the opposite rubber magnet.

 

3. Different applications: the same-sex rubber magnet is mainly used in refrigerator magnets, car stickers, printing products, and promotional products. The opposite rubber magnet is widely used in micro motor computers, laser printers, photocopiers, magnetic toys and other fields.
