Magnetic fuel treatment and magnetic water treatment

     Magnetic fuel treatment and magnetic water treatment, as their names suggest, are both methods of cleaning waste fuel and sewage that cause environmental pollution through the rational use of magnetic fields, making a huge contribution to environmental protection.     Their respective principles:        Magnetic fuel treatment is typically implemented by installing magnetic devices into fuel lines or fuel supply systems. Its working principle is based on the influence of magnetic fields on ions, molecules and particles in the liquid, thereby changing the physical and chemical properties of the fuel.The main principle of magnetic water treatment is to use magnetic fields to affect ions, molecules and tiny suspended solids in water to improve water fluidity and reduce scale and scale accumulation problems.   Their different effects:        For magnetic fuel treatment:   1. Improve combustion efficiency: The magnetic field can better mix the ions and molecules in the fuel, enhance the flammability of the fuel, and improve combustion efficiency.   2. Reduce emissions: Magnetic fuel processors are said to reduce the generation of emissions, such as reducing nitrogen oxides (NOx) and carbon emissions.        For magnetic water treatment:     1. Reduce scale: It is said that after magnetic water treatment, calcium and magnesium plasma in the water exist in a non-crystalline form, thereby reducing the generation of scale and extending the service life of the equipment.   2. Improve water quality: It is claimed that magnetic water treatment can improve water solubility, increase water absorption capacity, and improve plant growth and animal health.   3. Save energy: Some people believe that magnetic water treatment can reduce the resistance of pipes and equipment and improve the fluidity of water, thereby saving energy consumption.        However, there are some controversies about the scientific mechanism and practical effects of magnetic fuel treatment and magnetic water treatment that have not been fully proven and widely accepted. Some studies have shown that under actual conditions of use, the impact of magnetic fuel treatment on fuel is very limited, and its effect may depend on factors such as fuel type, combustion equipment, and operating conditions; the effect of magnetic water treatment depends on the strength of the magnetic field and the characteristics of the water. , flow rate and other factors vary.        Therefore, when considering magnetic fuel processors and magnetic water treatment systems, it is recommended to carefully evaluate their effectiveness and cost-effectiveness and consult with professionals to ensure optimal water treatment methods and results.

The reason why the epoxy coating of neodymium magnets falls off

     As we all know, electroplating the surface of neodymium magnets is a common method to extend their service life. However, when operating in humidity or sea water, the coating on the surface of neodymium magnets may also fall off or be corroded. Among them, for custom epoxy-coated neodymium magnets, salt dissolution reaction is one of the common reasons.          Next we are going to introduce some reasons that may cause the epoxy coating to peel off. We hope it will be helpful to you.      1.Improper surface preparation:        The adhesion of epoxy coatings is highly dependent on the quality of the surface preparation. If there are impurities such as oil, water vapor, and dust on the surface of the neodymium magnet, it will seriously affect the adhesion between the paint and the base layer, causing the epoxy resin to fall off.        2. Improper operation:        Neodymium magnets with epoxy plating may be subject to physical damage during use or handling, such as being struck, scratched, or bent, which may cause the coating to peel off. If the thickness of the epoxy resin coating is too thin, or the coating is exposed to water without being fully cured, it will cause the epoxy resin texture to crack and fall off.        3. Poor raw materials:        The quality of paint is directly related to the adhesion performance of the coating. If there are problems with the coating formula, production process, raw material selection, etc., such as containing volatile organic compounds and water, and inappropriate viscosity and solid content, it will easily cause the epoxy resin to fall off.          4.Bad working environment:        First of all, the construction of epoxy resin coatings requires that the ambient temperature is generally no less than 5°C. Exceeding the construction temperature range or improper air flow control may cause the epoxy resin to fall off. Secondly, in a humid environment, epoxy resin easily absorbs moisture, resulting in longer curing time or incomplete curing, which can easily lead to falling off. Finally, strong epoxy coated neodymium magnets may react when in contact with certain chemicals, causing damage to the coating. In particular, strong acids, alkalis or corrosive solutions may damage the coating.        To reduce the risk of coating peeling, choose neodymium magnets with good coating quality to ensure high durability and coating adhesion; handle magnets with care and avoid hitting, scratching or bending them; avoid Exposing neodymium magnets to chemicals such as strong acids, alkalis, or corrosive solutions, etc.          If you find that the coating of a neodymium magnet is peeling off, you should stop using it and consider recoating or replacing the neodymium magnet to ensure its proper functioning and protection, welcome to consult with professional neodymium magnet manufacturers.

Different types of magnetic fields

     The core of a magnetic field is the area around a magnet where magnetic forces are exerted. Magnetic fields are usually generated both through magnetic materials and through moving electric charges. Magnetic fields are invisible but can be detected using certain tools and materials. For example, in strong neodymium magnet materials, the magnetic field is generated by the arrangement of the magnetic moments of electrons within the material and is an inherent property of substances such as iron, nickel and cobalt.    Common magnetic field applications in life        1. Magnetic cards and magnetic strips: Commonly used magnetic cards such as bank cards, credit cards, access control cards, etc. all contain magnetic strips. These magnetic strips contain specific magnetic field codes used to store and read data.        2. Speaker: The speaker generates vibration in the magnetic field through electric current, thereby producing sound. They are widely used in audio systems, televisions, computers and other equipment.        3. Electronic devices: Storage devices such as hard drives and magnetic tapes use magnetic fields to read and write data, and are widely used in computers and data storage.        4. Motors and generators: Motors and generators are devices that convert electrical energy into mechanical energy using magnetic fields generated by custom curved neodymium magnets. Widely used in power tools, household appliances, transportation and other fields.        5. Magnetic Resonance Imaging (MRI): MRI uses powerful magnetic fields and harmless radio waves to produce detailed images of the inside of the body, which is important for diagnosis and medical research.          Magnetic fields are not just theoretical or used in advanced science. They are used in many aspects of modern life.        Different magnetic fields of magnets        1. Magnetic field of independent neodymium magnet in free space        For a custom strong ndfeb magnet in an independent space, the magnetic field is generated by two polarities (north and south poles) and forms magnetic field lines in the space. Magnetic field lines flow from the south pole of the magnet to the north pole, forming a closed loop. Near the magnet, the magnetic field lines will be denser, indicating a stronger magnetic field; while farther away from the magnet, the magnetic field lines will become sparse, indicating a smaller magnetic field. The strength of the magnetic field gradually weakens with distance.        2. The magnetic field generated by the neodymium magnet on the steel plate        On the steel plate, the magnetic field of the magnet will be affected by the shielding effect of the steel plate, and the magnetic field distribution becomes more complex. The strength and distribution of the magnetic field will depend on the material and thickness of the steel plate and the distance between the magnet and the steel plate.        3. The magnetic field generated between two magnets        Depending on the relative position and polarity of the magnets, an attraction or repulsion effect may occur between the two magnets.   (1) Attraction effect: When the north and south poles of two magnets are close to each other, an attraction effect occurs between them. Magnetic field lines exit one magnetic pole and enter the other, forming a closed loop.   (2) Repulsion effect: When two magnets of the same polarity (two north poles or two south poles) are close to each other, a repulsion effect will occur between them. Magnetic field lines will try to spread out to minimize magnetic energy, so the magnets will push each other away.

Common Testing Items for Sintered Neodymium Magnets

     Strong sintered neodymium magnets are widely used in household appliances, transportation, medical health, aerospace and other fields due to its ultra-high magnetic energy density (currently up to 1.5T on the market) and good service characteristics. In order to meet the use requirements of neodymium magnets in different fields and objectively evaluate the applicability and quality of the magnets, it is usually necessary to conduct various index tests on neodymium magnets. Generally speaking, we divide the testing content into three Aspects: First, product appearance size and physical properties; second, product magnetic properties; and third, product performance auxiliary testing items.     1. Appearance size and physical performance testing        The appearance size and physical properties of neodymium products are the basic requirements for product use. A good product must not only meet the magnetic performance requirements, but also need various sizes, coatings, mechanical properties, etc. that conform to actual needs to meet basic assembly and use requirements in different environments.         Product dimensions and tolerances not only affect the assembly effect, but also affect the consistency deviation of magnetic properties, motor operation stability and energy consumption. In actual use, they have attracted more and more customer attention.     2. Magnetic performance testing        The magnetic properties of neodymium are the main requirements for use. Only products that strictly meet the magnetic properties requirements can fully exert their effectiveness in the fields we need and carry out stable applications. This requires us to strictly test the magnetic performance indicators of neodymium.        In terms of magnetic properties, in the early days, everyone focused on the two indicators of remanence Br and intrinsic coercive force Hcj. Now, more and more users are paying attention to magnetic moment and thermal demagnetization. In fact, we use neodymium magnets mainly for its two important characteristics, one is the magnetic energy density per unit volume, and the other is the magnetic stability of high-temperature operation. It is more reasonable to use magnetic moment and thermal demagnetization to evaluate. High performance NdFeB magnets selected using thermal demagnetization indicators will undoubtedly have better service reliability and higher cost performance.   NdFeB Magnets Performance Parameters Grade Br Hcb Hcj (Bh)max Tw Grade mT kGs kA/m kOe kA/m kOe kJ/m3 MGOe ℃ N35 1170-1220 11.7-12.2 >868 >10.9 >955 >12 263-287 33-36 <80 N38 1220-1250 12.2-12.5 >899 >11.3 >955 >12 287-310 38-39 <80 N40 1250-1280 12.5-12.8 >907 >11.4 >955 >12 302-326 38-41 <80 N42 1280-1320 12.8-13.2 >915 >11.5 >955 >12 318-342 40-43 <80 N48 1380-1420 13.8-14.2 >923 >11.6 >955 >12 366-390 46-49 <80 N50 1400-1450 14.0-14.5 >796 >10 >876 >11 382-406 48-49 <80 N52 1430-1480 14.3-14.8 >796 >10 >876 >11 398-422 50-53 <80   3. Auxiliary testing items        The auxiliary testing items of neodymium are mainly to check whether the product performance meets expectations during the production process and to verify whether there are any defects in the production process; when abnormal conditions occur or new products are developed, the product composition and appearance are analyzed and confirmed.        The above are the common testing items for neodymium magnets. We are a professional neodymium magnets manufacturer. If you want to know more about neodymium magnets, please feel free to contact us.
