Diameter of particle size is the fundamental property of powder body, and especially for nano metal powder, size directly affects the character such as the fusion temperature of powder body, oxidizing temperature, mobility, can affect production practical application further. Using the nikel powder that PVD method prepares gained to belong to extra-fine nickel powder, extra-fine nickel powder is because particle diameter is little, and surface area ratio is big, is magnetic material, it is easy to agglomeration occur. This problem also perplexs many manufacturers and powder body supplier, therefore correctly effectively and rapidly detects the particle size distribution of powder body, could not affect the production of next procedure.
When metal-powder detects particle size distribution, conventional medium is ethanol and water. But doing medium with ethanol, one is that cost is big, and two meeting environmental pollutions, three, because ethanol belongs to flammable and explosive substance, also exist certain danger. And selection pure water is when doing medium, there is the problem that hydrophilic is not good between pure water and nikel powder, particularly powder diameter is more little, and its hydrophilic is more poor.
Therefore, we are when detection little particle diameter nikel powder such as extra-fine nickel powder particle size distribution, it is preferably selected a kind of surfactant, by different piece in molecule respectively for biphase affine of nikel powder and water, make the biphase composition that all the other side is regarded as this phase, surfactant molecule arranges between the two phases, biphase surface is made to be equivalent to proceed to intramolecule, thus reducing surface tension, increase the hydrophilic of nikel powder, nikel powder is made fully dispersed to open, it is thus possible to reflect powder body actual grain size distribution situation more realistically.
Summary of the invention
The technical problem to be solved is for above the deficiencies in the prior art, a kind of method for testing extra-fine nickel powder particle size distribution is provided, the method selects daiamid to be surfactant, make extra-fine nickel powder good hydrophilic property, it is thus possible to reflect extra-fine nickel powder actual grain size distribution situation more realistically.
The technical solution adopted in the present invention is:
A kind of method for testing extra-fine nickel powder particle size distribution, the method includes following operating procedure:

(3) standard sample carried with Laser particle-size distribution detector carries out instrument self checking, makes Laser particle-size distribution detector be in detection steady statue;
(4) the extra-fine nickel powder solution that reverse osmosis water preparation quality percent by volume is 0.01-1% that step (1) prepares is adopted, wherein extra-fine nickel powder adopts physical vaporous deposition to prepare, the daiamid solution that step (2) prepares is added again toward extra-fine nickel powder solution, the amount of reverse osmosis water=(0.5-2ml) 150ml in the addition extra-fine nickel powder solution of daiamid solution, then adds agitator dispersion 15-20min with ultrasound wave;
(5) step (4) gained liquid is detected under Laser particle-size distribution detector, obtain the particle size distribution situation of extra-fine nickel powder.
As preferably, in described step (2), the concentration of daiamid solution is 2-8%.
As preferably, in described step (4), the mean diameter of extra-fine nickel powder is 200 ± 20nm, is shaped as spherical.
Compared with prior art, the present invention has following remarkable advantage and beneficial effect:
Laser particle-size distribution detector can make laser produce this physical phenomenon of scattering test particle size distribution according to granule, thus use this equipment to make powder body fully dispersed come when carrying out powder granularity distribution detection, do not occur to reunite extremely important. The present invention is through big quantity research and test, finally determine daiamid as surfactant, increase the hydrophilic of the extra-fine nickel powder that PVD method prepares, extra-fine nickel powder is made can fully dispersed to open in water, thus reflecting the actual grain size distribution situation of extra-fine nickel powder more realistically, it is effectively ensured the accuracy of particle size distribution detection. Further, daiamid is easily bought, cheap, is adapted to actual production operation.
