Wear-resistant ceramic installation
Written from Pingxiang chemshun ceramics co.ltd
Modern engineering ceramics have excellent resistance to abrasion & corrosion , wear resistance
property just is second only to diamond, and light weight, only half of the metal, so it is chosen
for use as an anti-corrosion and wear-resistant surface material. Through the appropriate process
to connect ceramics with metal , the ceramic as a work surface, and the substrate using an ordinary
metal material, so that you can give full play to the ceramic with wear corrosion resistance,while playing
the metal material’s role of high strength and toughness, Under the premise of reducing the cost , it largely
increase the equipment life.
Ceramic wear resistance property is widely recognized, it is very concerned about the ability to ensure
that the installation of the ceramic device is not broken, do not fall off. This is also a key process in use,
if the abrasion resistance selection is unreasonable,it is likely to cause the shedding of ceramics,
Currently there are a variety of ceramic most common installation, including paste-type, welded,
dovetail mounted cassette .

a key process in use, if the abrasion resistance selection is unreasonable,it is likely to cause

including paste-type, welded, dovetail mounted cassette .
1. Paste formula
Stick-on installation is simple, low cost, especially for large-scale construction site, saving
maintenance time. The key is to stick-on adhesive and construction technology. Cement
Producing equipment is generally with higher temperatures, the traditional process using
epoxy glue wear-resistant ceramic. Such adhesives are mainly organic ingredients, not
resistant to high temperature (maximum temperature 150 ℃), and easy to aging. Can
not meet the requirements of long-running, Once running under the condition of ultra
high temperature for long time, the glue can easily become aging and crisp. Especially
in the case of sudden encounter hot quench thermal expansion coefficient of the ceramic
and steel inconsistencies, coupled with an organic adhesive brittle, it can easily lead to
monolithic ceramics spalling.
This issue has now been resolved, it is understood, now producing high-temperature inorganic
binders, such adhesive highest temperature 350 ℃, can be cured at room temperature, with a
very high strength and toughness. Especially noteworthy is that this glue thermal expansion
coefficient between the steel and ceramics (9 × 10-6m / mK), while the micro-fiber structure
of the adhesive can be well adjusted due to the thermal expansion of the ceramic and steel
inconsistencies brought to ceramic extrusion, to ensure maximum ceramics does not fall off
in a variety of harsh environments and long-term operation.
2. Welding
Welding is a welding hole through the middle of the ceramic ceramic welding on the device,
in conjunction with the adhesive paste to achieve the purpose of double insurance. Welded
pipes suitable for high temperature (500 ℃) or a slight impact of parts, such as kiln dust
piping, humidifying tower and export pipelines
