What is the purpose of the rare earth ndfeb magnet?
_ ndfeb strong magnet manufacturers
Rare earths, has greatly improve the quality and function of the other products of wonders.
In terms of the new material is as follows: the main purpose of magnetism, some rare earth elements of multiple electronic track is a single electron, magnetic moment.
Permanent magnet, ndfeb magnet, samarium iron nitrogen;
For computer, new energy cars, wind power, energy-saving home appliances category.
Paramagnetic refrigeration, use the demagnetization absorption features of paramagnetic material, under the condition of extremely low temperature refrigeration, the material such as gadolinium (
Gallium nitride (
Using spectral characteristics.
The foundation of rare earth tricolor phosphor powder, energy-saving lamps.
R red: of Y2O3: Eu3 + yttrium europium activated oxidation, green (G
Cerium MgAl1O19 terbium activated magnesium aluminate blue B: BaMgAl10O17: Eu2 + europium activated magnesium aluminate barium white LED, metal halide lamp, plasma PDP, LCD backlight CCFL also need rare earth elements, etc.
Use and other elements of the coordination, the complex function, make the catalyst.
Oil cracking, etc. )
Rubber, etc. )
Small molecules (
Processing nitrogen oxides, etc. )
Material modification (
Is still a coordination complex functions, do stabilizer)
PVC PVC plastic ageing, the enhancement and packing, the coupling effect of discontinuous chlorine atom chain reaction (
Can lead to plastic degradation)
: polyurethane heat;
Ultraviolet, to use its absorption function of 230 ~ 320 nm uv light.
Ageing resistance, added to the film, rubber, paint and other polymer materials.
Agriculture: ultraviolet light to red orange light, increase plant photosynthetic effect to increase production.
Cerium (high-end polishing:
Oxide, the polishing glass, semiconductor, etc, advantage is with a chemical effect and physical effect (
Thermal USES: thermal barrier material thermal barrier, resistance to high temperature 1400 ℃, and the thermal conductivity and thermal dispersion rate is still low;
Absorption of heat, make coating, enhance the radiation heat of more than 30%.
Compared with other hydrogen storage materials, hydrogen storage, easy activation, equilibrium pressure is moderate, high impurity gas poison, put hydrogen absorption balance pressure difference is small, typical of LaNi5 (
Rare earth lanthanum nickel alloy)
, new energy car batteries and other electrical appliances.
Agriculture, forestry and fishing: do fertilizer additive, quite do wonders;
Do feed additive, is special.
