Preparation method of gel forming ultra-high-purity alumina ceramic lining disk trimming ring

Abstract

The invention discloses a preparation method of a gel forming ultra-high-purity alumina ceramic lining disk trimming ring, wherein the preparation method comprises the following steps: 1) firstly, preparing a premixed liquid; 2) then adding a ceramic powder to the premixed liquid, carrying out ball milling, and forming a suspension slurry; 3) after the suspension slurry is stable, respectively adding an initiator and a catalyst, discharging from the ball mill, then adding a defoaming agent, and stirring evenly; 4) followed by pouring the treated slurry into a mold by an extrusion molding device; and 5) after a blank body reach the demoulding strength, soaking the demoulded blank body, cooling to room temperature, then taking out the blank body, grinding with sandpaper with the particle size of 600, and thus forming the alumina ceramic lining disk trimming ring. The manufacturing technological process of the alumina ceramic lining disk trimming ring is simplified, a traditional way of mechanical processing under high strength is changed, the assembly line production can be achieved, the manufacturing cost of the alumina ceramic lining disk trimming ring is reduced, and at the same time, the quality and performance of the alumina ceramic lining disk trimming ring are improved.

Description

technical field [0001] The invention relates to a preparation method of a gel-formed ultra-high-purity alumina ceramic liner dressing ring. Background technique [0002] Alumina ceramic materials are widely used, and the key technology for its production is the molding of high-quality blanks. At present, industrial production at home and abroad is mostly prepared by rolling film method, hot die casting method and organic slurry casting method, which generally have the problems of large equipment investment, high raw material cost and large environmental pollution. Contents of the invention [0003] The purpose of the present invention is to provide a technical solution for the preparation method of the gel-formed ultra-high-purity alumina ceramic lining disc dressing ring, which simplifies the manufacturing process of the alumina ceramic lining disc dressing ring in view of the deficiencies in the prior art The process has changed the traditional way of high-strength mach...
