Problems solved by technology

[0004] However, milled filaments tend to bend and lose their shape when produced by extrusion, and extrusion of fine diameter (e.g., less than about ANSI Size 16 grain size) filaments may result in extrusion through smaller diameter orifices. technical problems

Embodiment 1

[0114] Boehmite sol-gel samples were prepared using the following recipe: 1600 parts of DISPERAL alumina monohydrate powder (Texas Sasol North America Inc., Houston, Texas (Sasol North America Inc., Houston, Texas)) is dispersed. The resulting sol-gel was aged for 1 hour. The sol-gel was pressed into a polypropylene tool comprising parallel linear grooves (1.15 mm width at the top) interrupted by barriers (i.e. walls of 0.917 mm height) spaced at regular intervals of 2.75 mm. mm, depth 1.00mm, width 0.15mm at the bottom), such as figure 2 shown. The barrier does not extend to the same vertical height as the walls of the trench.

[0115] Topical peanut oil was obtained by brushing about 2 grams of a 1% by weight solution of peanut oil in methanol onto a sheet having a size of about 10 inches to 36 inches (25 cm 91 cm) before pressing the gel into the acrylic tool. coating. Apply the sol-gel to the sheet using a putty knife so that the grooves are completely filled. The s...

Abstract

An abrasive article includes an elongate abrasive particle held in at least one binder, the elongate abrasive particle including a ceramic body defined by at least two longitudinally oriented abutment surfaces, and a first end and a second end separated by the at least two longitudinally oriented abutment surfaces, wherein at least one of the first end portion and the second end portion includes both a molded portion and a fractured portion.

Description

[0001] This application was submitted on April 1, 2020 (international filing date: September 14, 2018), the title of the invention is "elongated abrasive particles, its preparation method, and abrasive products containing elongated abrasive particles", and the application number is 201880064266.9 (International application number: PCT / IB2018 / 057061) is a divisional application of the invention patent application. technical field [0002] The present disclosure broadly relates to elongated abrasive particles, methods of making abrasive particles, and abrasive articles comprising abrasive particles. Background technique [0003] Extruded rod-shaped abrasive particles, such as alumina particles, have existed for many years. They may be formed, for example, by extrusion of a dispersion or slurry of abrasive precursor material. The extruded material is cut or broken into desired lengths and fired. In those applications where the resulting abrasive material is alpha alumina, fin...
