Abrasive materials for use in abrasive-jet systems and associated materials, apparatuses, systems, and methods

摘要

Abrasive materials for use in abrasive jet systems and associated materials, apparatuses, systems, and methods are disclosed. An abrasive material configured in accordance with a particular embodiment includes abrasive particles individually including an abrasive core and a fluid-repelling coating. The individual abrasive cores can be monolithic and have outer surfaces. The individual fluid-repelling coatings can include an amide wax and/or other suitable materials and can extend around at least about 95% of the outer surfaces of the corresponding abrasive cores. An average sieve diameter of the abrasive particles can be from about 5 microns to about 35 microns. A method for making abrasive materials in accordance with a particular embodiment includes introducing abrasive cores into a mixer, introducing particles of a non-liquid fluid-repelling material into the mixer, introducing an anti-clumping material into the mixer, and mixing the abrasive cores, the fluid-repelling material, and the anti-clumping material.

主权项

1. A method, comprising:
introducing abrasive cores into a mixer; introducing a fluid-repelling material into the mixer, the fluid-repelling material being non-liquid and softer than the abrasive cores; introducing an anti-clumping material into the mixer; and mixing the abrasive cores, the fluid-repelling material, and the anti-clumping material within the mixer to form abrasive particles, wherein the mixing includes mixing the abrasive cores, the fluid-repelling material, and the anti-clumping material while a weight ratio of the abrasive cores to the fluid-repelling material is within a range from 50:1 to 600:1.
