1, the product description:

Nano-iron
tetroxide(Fe3O4) powder, with a certain magnetism, and the outer
magnetic field can be directional movement, size within a certain range
with a super-paramagnetic, as well as under the action of external
alternating electromagnetic field to generate heat and so on features,
its chemical performance is stable, and thus a wide range of uses.

Iron
oxide nano-placed four medium, the use of plastic melting method and
add the modifier method of dispersing agent, by adsorption of particles
formed on the surface electric double layer structure of nano-particles
to prevent reunite dispersed preparation of a stable water-based and
organic nano - magnetic fluid. Preparation of magnetic fluid two to 12
months can be a very good dispersion of the magnetic particles in the
liquid mean diameter of between 16 ~ 35nm.

2, technical indicators:

The
unit self-developed nano-iron oxide magnetic powder 4, with an average
diameter of about 20nm, with super-paramagnetic iron oxide water-based
slurry levels ranging from 0.5 ~ 20% (mass percentage), slurry 30nm
diameter iron oxide dispersed about the stability of slurry put it
aside in a year or so.

3, add the amount of product use:

Fe3O4
nano-slurry application scope is wide, for different applications to
add a larger amount of difference, generally ranging from 0.5 ~ 50% (in
percentage terms, the quality of nano-powders).
