Method for preparing ceramic bond stacking abrasive material through centrifugal drying granulation technology

Abstract

The invention provides a method for preparing a ceramic bond stacking abrasive material through a centrifugal drying granulation technology. The method is characterized in that an abrasive material and ceramic bond powder composed of silicon oxide powder, aluminum oxide powder, lithium carbonate powder, sodium carbonate powder, boric acid powder and zirconium oxide powder are adopted as the raw materials, mixed slurry is obtained by adding deionized water and dextrin liquid into the raw materials, stacking abrasive material fresh pellets are obtained through centrifugal drying, and the ceramic bond stacking abrasive material can be obtained through calcination. The abrasive material can be evenly wrapped and high bonding force can be generated through the liquid phase formed after the powder bond in the stacking abrasive material is fused. The spherical stacking abrasive material prepared through the method has the characteristics of the uniform particle granularity and the uniform organization structure, and can be used for preparing abrasive cloth, abrasive belts and resin bond grinding wheels. The abrasive belts prepared from the ceramic bond stacking abrasive material have the characteristics of being high in grinding efficiency, good in self-sharpening performance and grinding heat dissipation and long in service life; automatic production can be easily achieved through the technology.

Description

Technical field [0001] The invention relates to a preparation method for preparing ceramic bond accumulation abrasives by using centrifugal drying granulation technology. Background technique [0002] Abrasive belt is a belt-shaped tool that can be used for grinding and polishing, which is made by bonding abrasives to flexible materials using adhesives. The three elements of the abrasive belt are: substrate, abrasive and adhesive. The currently used abrasive belts have the following disadvantages due to the use of ordinary structural abrasives: (1) Single-layer abrasive belts have thin working layers, short service life and low utilization rate. Frequent replacement reduces production efficiency and improves operator labor. Strength; (2) The gap between abrasive grains on the abrasive belt is small, and the abrasive debris will remain on the surface of the abrasive belt during the grinding process, causing blockage, increasing friction and heating, and the workpiece is easy to bu...

The currently used abrasive belts have the following disadvantages due to the use of ordinary structural abrasives: (1) the working layer of the single-layer abrasive belt is thin, the service life is short, and the utilization rate is low. Frequent replacement reduces production efficiency and increases the labor of the operator. Strength; (2) The gap between the abrasive grains on the abrasive belt is small, and the abrasive debris will remain on the surface of the abrasive belt during the grinding process to cause blockage, increase friction and heat, and the workpiece is easy to burn; (3) The traditional single-layer abrasive belt is grinding During the process, after the blunt abrasive falls off, the friction between the adhesive and the workpiece is caused, so that the abrasive belt cannot continue to work stably; (3) the state of the abrasive grains in the grinding process and the The grinding force is different, so the surface quality of the ground workpiece is quite different, and the single-layer abrasi
