Ceramic Collision Ring Zirconia Valve Seat High-pressure Rod Zirconia Parts Homogenizer Components

Part Name: a set of high-pressure rod &high-pressure seat &collision ring

The three parts work together in a homogenizer machine.

Specifications: High-pressure rod φ20*L60

High-pressure seat φ40*20*L26

Collision ring: φ40*φ20*L20

Materials: Yttria-stabilized zirconia

Yttria-stabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxide. These oxides are commonly called "zirconia" (ZrO2) and "yttria" (Y2O3), hence the name

Properties:

Powerful interatomic bonds endows zirconia ceramics not only with high hardness and wear resistance, but also a resistance to corrosion. Since they also tolerate high temperature, zirconia ceramics, they have obtained a permanent place in food and beverage industry, which meet their exacting requirements.

Advantages of zirconia parts:

·High wear, heat, pressure, and chemical attack resistance (gas and liquids)

·Extreme hardness

·Excellent electrical insulation

·Relatively lightweight

Application: After shaping and sintering, Yttria-stabilized zirconia’s hardness reaches HV2500, and has good properties as wear resistance, anti-corrosion, high temperature resistance, as well as excellent finish surface. In addition to its good properties of elasticity module and high hardness, it produces no non-toxic materials when working. So USDA approves it for contact with food products. In food and beverage industries, big molecule is pulverized into smaller ones by homogenizer, in which installed zirconia rings, zirconia rod/plug, zirconia seat. Under the conditions of high-pressure and high-speed, zirconia parts work long time without few changes. If price is not concerned, yttria-stabilized zirconia is a better material option than alumina ceramics
