NOZZLE FOR HIGH PRESSURE INJECTION PROCESSING DEVICE, EVALUATION METHOD FOR HIGH PRESSURE INJECTION PROCESSING DEVICE, AND HIGH PRESSURE INJECTION PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To control energy in a nozzle by combining various nozzle chips different in diameter, to realize efficient micronization processing, and to use the nozzle according to purposes, such as micronization processing and defiberizing processing.;SOLUTION: The high pressure injection processing device nozzle that generate and micronizes cavitation by high-pressure injecting a raw material mixed liquid from the nozzle by prescribed pressure is provided with: a nozzle tip Nn having a through-hole; and a nozzle holder Nh, and characterized in that the ratio (Wn/Dn) of the thickness Wn of the through-hole of the nozzle tip to the diameter Dn of the through-hole of the nozzle tip is set to 10 or higher, the diameter Dn of the through-hole is set to 0.16 mm or less, and efficient micronization and various micronization modes are realized by dividing the tip and changing the diameter thereof.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
