Zirconia ceramic plate and tiles
Application
KSINO is a professional manufacturer of structural ceramics, focusing on the production and processing of ceramic structural parts with zirconia, alumina and ZTA as raw materials. The ceramic structural parts produced by Kezhong Industrial Ceramics Factory have excellent physical and chemical properties and are widely used in the industrial market. However, as zirconia, alumina, ZTA and other ceramic raw materials are not known to the public, users are not very clear about how to choose raw materials. Today, Kezhong Industrial Ceramics Factory will briefly compare zirconia, alumina and ZTA in the following aspects.

Zirconia ceramic products
1、 Zirconia ceramic cylinder liner and plunger
Zirconia ceramic cylinder liners and plungers have the characteristics of wear resistance, corrosion resistance, high temperature resistance, high strength, high hardness, long life and impact resistance. They are widely used in oil and gas development with mud pumps, oil well pumps, water injection pumps, fracturing pumps and other equipment. Their product performance has been increased by 8-10 times compared with metal products, greatly improving oil and gas production efficiency, reducing production costs, and having good economic and social benefits.
2、 Sand mill accessories
With the wide application of new energy and nano new materials, the demand for horizontal sand mill, vertical sand mill, stirring mill and other kinds of ultra-fine grinding equipment is also rising. Zirconia ceramic accessories (including grinding plate, turbine and swing wheel, rod pin sleeve, rod nail, grinding block, screen, etc.) are widely used in electrode materials, nano materials, printing ink, medicine, chemical industry, ceramics and other industries because of their excellent performance, small wear and other advantages, which effectively improve the grinding efficiency of grinding equipment and reduce wear.
3、 Wear-resistant ceramics
Zirconia wear-resistant ceramics have the advantages of high hardness, high strength, good wear resistance, long service life, heat resistance and impact resistance, and can withstand various tests in harsh working environments. Therefore, they are often used in the fields of grinding and polishing materials, wear-resistant coatings, pipe or equipment linings, equipment structures, etc. Common zirconia wear-resistant ceramic products include wear-resistant cylinder, wear-resistant block, lining plate, lining brick and lining, etc. Different product types and specifications can be selected according to different equipment and use conditions.
4、 Yellow zirconia
Yellow zirconia is mainly used in various zirconia wire drawing wheels, wire pulling wheels and tower wheels. The material has high strength, corrosion resistance, high wear resistance, good self lubrication, good thermal stability, fatigue resistance and excellent cost performance.
5、 Zirconia grinding medium and micro bead
Zirconia beads are made of micron and sub nanometer zirconia and yttrium oxide by isostatic pressing. Due to its extremely low grinding loss, high density, strong toughness, high hardness, high temperature resistance, acid and alkali resistance, corrosion resistance, antimagnetism and other characteristics, it is commonly used for ultra-fine grinding and dispersion of materials that require "zero pollution", high viscosity and high hardness, and is commonly used in electronic ceramics, magnetic materials, zirconia, medicine and food, pigments, dyes, inks, special chemicals and other industries
