Observation can substantially understand diamond particle distribution situation and reunion situation, still, due to there is nickel dam covering, so for
Grain size can not pass through picture accurate evaluation.
The content of the invention
It is an object of the invention to provide a kind of method for detecting diamond wire diamond particles, to detect diamond wire
Particle size distribution situation and hardness, and then build full diamond wire quality estimating index.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of method for detecting diamond wire diamond particles, comprise the following steps：
（1）Diamond wire is chosen, its length is L, will be weighed after its ultrasound, drying, obtains weight g1；
（2）Then diamond wire is put into decoating liquid and carries out electrochemistry removing plating；
（3）Complete to be filtered decoating liquid after strip, clean, dry the diamond particles precipitated, and to diamond
The weight of grain is recorded, and obtains weight g2；
（4）Cleaning, drying is weighed again after diamond wire after strip is taken out, and obtains weight g3, coating is estimated according to loss of weight
Weight；
（5）By step（3）The diamond particles being collected into obtain granular size, circularities by Malvern laser particle size analyzer
And view data；
（6）According to step（5）Obtained data, draw diamond hardness.
The step（1）In, the length of diamond wire is 500-10000cm.
The step（2）In, decoating liquid is made up of the component of following content：
Sodium nitrate 150-300 g/L, boric acid 10-20g/L, edta edta 15-25g/L, ammonium thiocyanate 0.1-1g/
L, surplus are water.
The step（4）In, obtain the nickel dam weight of unit length on diamond wire=（g1-g2-g3）/L.
The step（6）In, the method for drawing diamond hardness is：
Using ball grinding method, fixed grinding technics, it is big to contrast the particle diameter the change of divergence before and after ball milling of the diamond on different steel wires
It is small；
Or contrasted using differential thermal analyzer by differential thermal analysis curve.
Beneficial effect：The method of the present invention can detect diamond particles actual size, while can further obtain difference
The diamond hardness difference of quality.Mainly for detection of diamond wire particle size distribution situation and hardness, and then build full Buddha's warrior attendant
Line quality estimating index.
