Third valve is provided on third pipeline.First, second, third valve is motor-operated control valve, is controlled and is connected by PLC, is realized
Full automatic unmanned.
Workflow:
By opening the first valve, sampled automatically, into sampling pond.
Retarder thinner passes through the conveying of pump, by the second valve, into sampling pond.
Third valve opening, the solution in sampling pond after dilution enter sample cell and are detected.
Material in sample cell passes through the light sensation region of Nicomp380 dynamic light scattering optics dynamics analyzer, light intensity with
Generation accordingly change.The optical signal that detector is collected simultaneously is converted into voltage signal, and different voltage signals is corresponding different
Particle size, to obtain accurate material particular diameter, the testing result of partial size is as shown in Figure 3.
