Abstract
Description
Technical Field
[0001] This utility model relates to the field of white fused alumina surface modification technology, and in particular to a device for white fused alumina surface modification by nanoparticle atomization spraying. Background Technology
[0002] White fused alumina is made from industrial alumina powder, smelted in an electric arc at temperatures above 2000℃ and then cooled. It has a slightly higher hardness than brown fused alumina, slightly lower toughness, high purity, good self-sharpening properties, strong grinding ability, low heat generation, high efficiency, resistance to acid and alkali corrosion, and good high-temperature thermal stability. In many high-end applications, the surface of white fused alumina needs to be modified to further enhance its performance, such as improving its bonding strength with other materials and its wear resistance.
[0003] Traditional wet chemical modification methods require large amounts of chemical reagents and water, which are not only costly but also generate a lot of wastewater, causing environmental pollution. Although physical coating methods are relatively environmentally friendly, the coating layer has weak adhesion to the white fused alumina surface and is prone to peeling off during use. Furthermore, the white fused alumina surface is only mixed and stirred by a stirring rod during modification, which is a single stirring process and is prone to uneven mixing. Therefore, we propose a nanoparticle atomization spraying device for white fused alumina surface modification. Utility Model Content

[0038] The specific operation is as follows: white fused alumina powder raw material is added to the inside of the white fused alumina raw material storage box 9 through the white fused alumina adding pipe 30. After the addition is completed, the white fused alumina raw material storage box 9 and the white fused alumina spraying modification box 5 are vacuumed by the vacuum pump 10.
