Product Description
The ceramic tile wear liners are an industrial wear-resistant, impact-resistant, corrosion-resistant material. It has shock resistance and thermal expansion and contraction. The thermal expansion coefficient of viscose is between steel and ceramics, which can be well adjusted due to the inconsistent thermal expansion of ceramics and steel. At the same time, a variety of flexible fibers are added to the adhesive to ensure that the ceramics will not fall off during long-term operation under the environment of vibration, frequent thermal expansion, and cold contraction.
Ceramic tile wear liners are produced with a unique formula of 95% Al2O3 added with a variety of wear-resistant materials. They are dry-pressed and have the characteristics of high density, high toughness and wear resistance.
Application advantages of thermal power plants
The powder exhaust fan is one of the main auxiliary machines in the power plant. The working principle of the powder exhaust fan is to send the pulverized coal from the coal mill to the boiler for combustion. For high wear conditions, wear-resistant ceramic sheets can be pasted on the fan volute to prolong the service life.
The wear-resistant ceramic sheet is fired from high-purity and ultra-fine alumina powder. It is sintered at a high temperature of 1700 degrees and formed by isostatic pressing. It also has ultra-high hardness and excellent resistance to diamond. Grinding ensures the wear resistance of ceramics.
The alumina ceramic patch has good wear resistance and is lightweight, which reduces the total weight of the impeller and increases the service life of the main bearing of the fan. In order to ensure the wear of the induced draft fan, the wear-resistant ceramic sheet can be used for the fan impeller superior.
The wear-resistant ceramic sheet is light and easy to install. The volute is pasted and welded with small ceramic blocks, which is convenient for maintenance and replacement. The excellent wear resistance and corrosion resistance make it have a long service life, which greatly saves maintenance costs.
Product Features
The wear liners is a special corundum ceramic made of aluminum oxide as the main raw material, rare metal oxide as a flux, and sintered at a high temperature of 1700℃, and then combined with a special rubber and a high-strength inorganic binder. It becomes:
(1) High hardness: its Rockwell hardness is 85-90.
(2) Good wear resistance and long service life: wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.
(3) Wide range of applications: wear liners include adhesive liners suitable for low-temperature environments, impact-resistant liners suitable for the impact of large pieces of materials, porcelain steel liners suitable for wind conveying, and high-speed operation suitable for dynamic operation. Of cemented ceramic fan blades.
Application of drum mixer
The cylindrical mixer in the sintering machine system originally used the structure of the polymer plastic lining plate with the pressure plate outside. This structure has an unreasonable internal material structure because after the pressure plate is worn, the material enters the structure and squeezes the lining plate away, and the lining plate is fixed. The bolts can not be disassembled and handled because it will cause the lining plate to fall off and cause equipment accidents. The material hanging in the cylinder not only increases the load of the equipment, but also causes poor discharge, and sometimes even discharges from the feeding port. The overall structure of the lining plate has a relatively high self-weight. The equipment load is greatly increased, resulting in a reduction in the life of the transmission components, high power consumption, and an increase in the equipment failure rate, which seriously affects the equipment operation rate.
The ceramic tile wear liners are firmly bonded and have good heat resistance. The wear-resistant ceramic liner is pasted on the inner wall of the equipment with heat-resistant super glue. Long-term operation at 350℃ without aging, good insulation performance, corrosion resistance, no pollution, the wear-resistant ceramic liner is light in weight. Its density is 3.6g/cm3, only half of steel, which can greatly reduce equipment load, according to our customer follow-up investigation for more than ten years, under the same working conditions, the service life of the equipment can be extended at least ten times. If the wear-resistant ceramic lining plate is replaced, the welding wear-resistant ceramic lining plate needs to be used for operation in a high-temperature environment, which has the following advantages:
1. The structure is simple, the weight is light, the material trajectory in the mixer is reasonable, and the thickness is suitable, which provides the conditions for further strengthening the mixing and pelletizing ability of the mixer.
2. Has good high-temperature resistant material scouring performance and wear resistance.
3. The effective diameter of the cylindrical mixer is enlarged.
4. The lining plate has a long service life, which reduces the daily labor intensity of the production system before maintenance.
FQA
What are ceramic tile wear liners
They are a thermal vulcanization process, vulcanizing toughened wear-resistant ceramics and rubber together to form a rubber-ceramic two-in-one liner, and then using high-strength organic adhesive to bond the liner to the inner shell steel plate of the equipment, to form a strong and cushioning anti-wear layer.
What are the categories of ceramic tile wear liners?
It can be divided into two-in-one wear-resistant ceramic lining plates and three-in-one wear-resistant ceramic lining plates.
Two-in-one wear-resistant ceramic lining plate = ceramic + steel plate or ceramic + rubber
Three-in-one wear-resistant ceramic lining plate = ceramic + rubber + steel plate three-in-one ceramic lining plate
Yibeinuo New Materials is a national high-tech manufacturing enterprise integrating ceramic tile wear liners manufacturing and technical services.
