It is earlier Nano diamond and surface modifier to be made into suspension


It is earlier Nanodiamond and surface modifier to be made into suspension that high-pressure liquid stream is pulverized, then, by booster, it is pressurized, when the pressure reaches a desirable value (more than the 200Mpa), spray to the diamond target plate at high speed by the injector, with its pulverizing and refinement, this process is capable of circulation carries out, until reaching required particle diameter. The method that airflow pulverized is to use two strands of compressed air with equal pressure and flow to enter in line from both sides and pulverize the district; material (Nanodiamond and chemical modifier) then enters by mechanism and pulverizes the community; during two bursts of high-velocity air head-on collisions, the Nanodiamond granule impact in the mixed airflow is crushed and modification. Adopt the airflow disintegrating apparatus, with Nano diamond, the compound of enuatrol and glycerine (anharmonic ratio of Nano diamond and modifier total amount is 1: 0.05) adds simultaneously from charging aperture, the Nano diamond aggregate is smashed and in time stable by the mode of mechanical crushing and chemical modification synchronous effect, centrifugal removal particle diameter surpasses the coarse granule of 500nm, it is sneaked into to regulate the pH value with the oxalic acid wetting agent be in 3 the deionized water, add surfactant sodium phosphate and stable dispersant polyethylene glycol, wherein the addition of sodium phosphate is 0.1%wt, the weight ratio of itself and Nano diamond is 0.05: 1, the addition of polyethylene glycol is 0.05%wt, the anharmonic ratio of polyethylene glycol and Nano diamond is 0.025: 1, and be 9 with the pH value that ammoniacal liquor is regulated suspension, ultrasonic dispersion got final product in 10 minutes, can make weight concentration is 2%, average grain diameter is the diamond suspension (size distribution is seen accompanying drawing 1) of 166.5nm, after the film classification, can get narrower particle size distribution, particle mean size is in the diamond suspension (size distribution is seen accompanying drawing 2) of 98.5nm.
