Wear-resistant ceramic rubber liner is mainly divided into three-in-one ceramic rubber liners and two-in-one ceramic rubber liners. The three-in-one liner is a combination of ceramic + rubber + steel plate, and the two-in-one liner is mainly ceramic + rubber. , The ceramic-rubber composite board is a thermal vulcanization process to vulcanize alumina ceramics with rubber and steel plates. It is mainly used for wear resistance, impact resistance, corrosion resistance, and wear resistance of major industrial and mining equipment.    1. The three-in-one ceramic rubber liner is installed by bolt welding; 2. The two-in-one ceramic rubber lining board is connected by a special adhesive. The wear-resistant ceramic rubber lining board has strong wear resistance. The rubber layer in the middle can play a buffering role and solve the problem of wear-resistant ceramics. It is caused by the different expansion coefficients between the steel plate and the steel plate, and it buffers the impact on the wear-resistant ceramics, improves the impact strength of the composite plate, and makes the material performance fully play. The production of the wear-resistant ceramic rubber composite plate is completed at one time. The quality of the ceramic liner is guaranteed, and the installation is convenient and quick; the high-strength adhesive bonds the composite board to the steel plate of the equipment to form a strong and cushioning anti-wear layer; both installation methods are convenient and quick.

Since the birth of lithium electronic battery products in the early 1990s, it has been 30 years. In recent years, with the rapid expansion of my country's 3C market and new energy vehicle market, Chinese companies have risen rapidly and occupy the largest scale in the world. In 2016, China accounted for 15 of the world's TOP 20 lithium battery manufacturers. By 2019, CATL and BYD have ranked among the top in the world in terms of shipments. Around the upstream and downstream of lithium battery manufacturers, a large and complete industrial chain has already been formed in China.   As an important part of the lithium battery, the cost of the cathode material also accounts for about 50% of the overall battery, and its quality is closely related to the quality of the lithium battery. On the lithium battery cathode material production line, from raw material delivery, feeding, batching, mixing, sintering (including secondary or tertiary sintering) to final packaging, each link is connected by pipelines into a closed transportation system, so the amount of pipelines is relatively large. Big. In the early days, PU pipes, rubber pipes and stainless steel pipes were mostly used for conveying pipes.   In the past three years, the rapid development of the domestic new energy automobile industry has put forward higher requirements on the safety performance and energy density of battery materials, and the high nickel ternary has become the mainstream. Compared with traditional cathode materials such as lithium iron phosphate, high-nickel ternary materials have higher hardness and higher requirements on the wear resistance of transportation pipelines. At the same time, they are also more stringent in demagnetization (forbidden copper, iron and zinc). Some manufacturers continue to use FRP liners, PTFE liners, and even tungsten carbide spray tubes that have been used in the lithium iron phosphate preparation system. After use, they find that the service life is extremely short. Some use of FRP straight pipes have leaks in many places within less than six months of the production line, while FRP lined elbow pipes even lasted less than a year on the ferro-phosphorus production line.   In fact, the integral wear-resistant ceramic liner has long been widely used in lithium battery production lines in Japan and South Korea. The integral wear-resistant ceramic lined elbow has the characteristics of super wear resistance, corrosion resistance and high temperature resistance. At the same time, as a non-metallic lining material with ultra-high hardness, the ceramic lined elbow can effectively block the contact between powder and iron and other harmful substances, reduce the content of iron and other impurities in the cathode material, and improve the safety performance of the battery.   The integral wear-resistant ceramic pipe steel produced by ibeno is integrally formed of 304 stainless steel (integral hot bending, non straight pipe welding), the inner wall is lined with 95 or 99 high-purity alumina ceramic pipe fired at 1700 degrees (most of 90 or 92 porcelain in the market), and the ceramic and steel pipe layer are filled with special adhesive. Different from the general ceramic lined composite pipe, this kind of pipe has smooth inner and outer walls, unobstructed air flow, very low wear, good pressure resistance and corrosion resistance. Practice has proved that, The service life of ibeno wear-resistant ceramic pipeline in high nickel ternary production line is at least five years.  

Wear-resistant ceramic adhesive, also called wear-resistant ceramic adhesive, refers to a high-performance adhesive specially used to paste wear-resistant ceramic sheets or linings to the surface of the equipment substrate to protect the equipment substrate from wear. Wear-resistant ceramic glue can stick the wear-resistant ceramic sheet tightly on the surface of damaged equipment such as metal, to extend the service life of these equipment, reduce the frequency of replacement, and save costs. Let's introduce to you today what are the special uses of wear-resistant ceramic glue.   1. Wear-resistant ceramic glue is used for sticking wear-resistant ceramic sheets on the top surface and the vertical surface of the equipment. With strong adhesion, ceramics will not fall off without other support measures during the construction process.   2. Wear-resistant ceramic glue is suitable for medium-speed coal mill cones, coarse powder separators, powder exhaust fans, pulverized coal pipelines, and other ash powder scouring equipment and steel, cement, coal, mining, and other industries that are subject to strong scouring of materials Or paste wear-resistant ceramic sheets on equipment that is eroded and worn.   3. It is difficult to achieve the connection between wear-resistant ceramics and metal parts of equipment through traditional connection methods such as welding. It is a practical test to use wear-resistant ceramic paste to bond to achieve the connection between wear-resistant ceramics and metal parts of equipment. A proven connection method. After development, this technology has now been extended to the power, metallurgy, mining, cement, and other industries and has been widely used and recognized. 4. The use of wear-resistant ceramic glue can bond the high-purity wear-resistant ceramic sheets very firmly to the surface of equipment that is severely washed by materials, prolong the service life of this equipment, and reduce the maintenance of such equipment, to reduce the replacement of new equipment and reduce The purpose of equipment operation and maintenance costs is to reduce production losses caused by downtime.   Instructions: 1. Substrate surface treatment: Grinding or sandblasting to remove dust, oil, and rust on the surface of the adherend, and finally clean it with a cleaning agent, and let it dry; 2. Glue preparation: mix the two components evenly in proportion; 3. Sizing coating: evenly apply the adjusted glue on the surface of the object to be adhered; 4. Adhesive layer curing: complete curing under the required conditions, and perform post-curing treatment.  

A coal mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment for pulverized coal furnaces. The coal grinding process is a process in which coal is broken and its surface area is constantly increasing, which is easy to wear. Coal pulverizers generally adopt ceramic chip wear-resistant protection. After a few years, the internal roller frame and hinge shaft, tripod, annular duct, and straight pipe, the inner wall of the separator, and the outlet powder pipe area of the coal pulverizer will be severely worn. , It is necessary to repair the severely worn and fallen parts of the wear-resistant ceramic sheet to ensure the safe and stable operation of the equipment.   Coal mill is a machine that crushes and grinds coal into pulverized coal.

The repairing construction process of the ceramic sheet of coal pulverizer: surface dust removal, mechanical rust removal → cleaning → coating ceramic sheet glue → pasting ceramic sheet → self-inspection and trimming.   2. Dust removal and rust removal on the surface of the coal mill: Use an angle grinder to clean up the floating dust and rust on the construction site, exposing the original steel body.   3. Manual mechanical polishing pretreatment: Use an angle grinder to clean and roughen it at a certain angle, and then clean the surface with alcohol to make it have a certain surface cleanliness and roughness, and the rust removal level is Sa2.   4. Cleaning of coal mill: clean the surface with cleaning agent after rust removal.   5. Apply wear-resistant ceramic viscose: mix ceramic sheet viscose and curing agent according to the ratio of 1/2, adjust the glue time in 2 minutes, so that the AB glue is evenly mixed, and then scrape coating on the construction site and the ceramic sheet, the adhesive Spread evenly, and there should be no leakage or air bubbles.   6. Paste the ceramic piece: repair the worn and uneven construction parts with a ceramic repair agent, and then paste the scraped ceramic pieces on the construction part in order and stagger, and tap it firmly with a rubber hammer. The welding seam is polished and smooth, the bonding is firm and smooth, and the gap between the ceramic sheets is not more than 0.5 mm.   7. Self-inspection and trimming: check after the paste is completed, the outer surface of the ceramic sheet is smooth and flat, without deep scratches and cracks, to ensure that the paste is flat and the surface is smooth, and the unqualified parts should be repaired in time.  

The pulverizing, ash, dust removal, and coal conveying systems of coal-fired power plants are constantly affected by friction, corrosion, collision, impact and other factors of the medium during the operation of the equipment, and the system is prone to leakage, causing environmental pollution. For this reason, each power plant has adopted different leakage control methods accordingly; among them, wear-resistant ceramic liner is an ideal leakage control material, and its wear resistance, practicability and economy are superior to other wear-resistant materials.   The wear-resistant ceramic lining is made of Al2O3 as the main raw material, and then some metals are used as the oxide as the solvent, and is made of corundum ceramics after being calcined at a high temperature of more than 1,000 degrees, so the wear-resistant ceramic lining does not matter. It is very high in hardness and wear resistance. Under normal circumstances, it is no problem to use it for up to 10 years.   The installation of the wear-resistant ceramic lining plate is mostly by using strong adhesive to paste the wear-resistant ceramic on the surface of the mechanical spare parts. Provide protection.    Wear-resistant ceramic liners are industrial wear-resistant, impact-resistant and corrosion-resistant materials. Shock resistance and thermal expansion and contraction: the thermal expansion coefficient of viscose is between steel and ceramics, which can well adjust the extrusion of ceramics 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 and frequent thermal expansion and contraction.   The wear-resistant ceramic lining plate can also be used as a wear-resistant material for the material conveying equipment of steel mills and power plants to flow through the surface of the pipeline. Its main function is to effectively resist the impact on the pipe wall and the corrosion of chemical substances when the material passes through. The thermal shock effect caused by the action and the passing of the material greatly reduces the wear and tear on the inside of the equipment components.  

After the raw coal is ground into the pulverized coal by the coal mill, it flows in the pipeline in the form of fluid and is transported to the furnace through the coal conveying pipeline. After a period of operation, the inner wall of the pipeline is severely eroded and worn by pulverized coal particles, and the wall thickness becomes thinner. In the elbow, the pipe wall is even worn by the pulverized coal, polluting the environment and reducing the efficiency. In order to improve the wear resistance of the pipeline, the selection of suitable high-strength structural adhesive wear-resistant ceramic lining can well avoid the wear of the pipeline, protect the pipeline and prolong the service life of the pipeline.    Wear-resistant ceramic pipes are made of high-temperature-resistant and strong adhesive to stick alumina ceramic sheets on the inner wall of the pipes, and after heating and curing, a firm anti-wear layer is formed. More than 15 times the steel pipe. The service life of ordinary pipes is half a year to one year, and the service life of wear-resistant ceramic pipes can reach 5-10 years, which greatly reduces the number of equipment downtime and maintenance, and saves a lot of manpower and material costs for enterprises. It is a very cost-effective anti-wear scheme for pulverized coal conveying pipelines.   The service life of the pulverized coal conveying pipeline lined with wear-resistant ceramics is greatly improved. The lined corundum ceramics have high hardness and are resistant to acid and alkali corrosion. , The lining is smooth and does not accumulate material.

Wear-resistant ceramic linings, ceramic pipes, rubber ceramic linings, ceramic rubber rollers, and other products have been widely used in the power industry. Alumina ceramics have strong wear resistance, impact resistance, high strength, light weight, firm installation, and good wear resistance. , which can greatly extend the service life of the equipment. 1. Powder pipeline: Most of the pulverized coal transportation pipelines in the combustion system of the power plant are made of O235 material. The inner wall of the pipeline is severely eroded and worn by fly ash particles during operation. In order to improve the wear resistance of the pipeline, a wear-resistant lining plate with a high-strength structure is selected, which can well avoid the wear of the pipeline and protect the pipeline.   2. Separator: The cyclone separator of the power plant is seriously worn, and the equipment parts are worn through or pierced by coal powder. Wear-resistant ceramic lining plates are used to play a wear-resistant role to prolong the service life of the separator.    3. Coal mill: The rapid grinding cone used in the power plant is seriously worn under the scouring of high-speed pulverized coal particles. The use of wear-resistant ceramic liners can effectively extend the service life of the equipment by 2-3 years.   4. Circulating water pump: During the use of the circulating water pump, the water pump is corroded, cavitated, worn, and corroded due to the reduction in the size of the pump casing and the impeller or the honeycomb surface. Perforations are severely repaired frequently.   Wear-resistant ceramic linings, ceramic pipes, rubber ceramic linings, and ceramic rubber rollers are not only used in power plants but also widely used in steel, coal, chemical, cement, wharf, machinery, and other industries. They are good wear-resistant materials.

Many metal and non-metal components in many beneficiation equipment are worn out due to continuous work, which affects production efficiency. Therefore, serious wear and short service life of beneficiation equipment have a serious impact on the development of beneficiation production.   The mineral processing equipment adopts industrial ceramic lining, which is mainly used to resist the damage to the pipeline caused by the scouring and wear of the mixed gas and prevent the mixed gas from leaking and polluting the environment due to wear. Grinding ceramic pipes not only makes full use of the high-temperature wear resistance and corrosion resistance of alumina ceramics but also makes full use of the advantages of high metal strength and high toughness. The integrated design is convenient for replacement and installation.    3mm thick wear-resistant ceramic lining is used to replace the original 4mm thick stainless steel wear-resistant layer. The inner surface of the pipeline is polished neatly with an angle grinder. According to the changes of ambient temperature in the season, the cylinder and 6 mm thick 95 alumina ceramic sheet are adhered together with high-strength non-magnetic adhesive under acceptable conditions, and gently beaten with a rubber hammer to make the height of the whole cylinder uniform, After 24 hours of operation, avoid uneven operation of the magnetic separator.   After the wear-resistant ceramic lining is used, the service life of the pipeline is increased from the previous one month to two years. The upgrade and transformation results are very large, which not only reduces the problems caused by wear and tear, but also effectively improves the work efficiency. Adding wear-resistant ceramic sheets to the equipment is not only resistant to high temperature, but also can effectively prevent the equipment from slipping, reduce the frictional impact in the equipment, keep the machinery in long-term production without damage, reduce maintenance, save production costs, and effectively extend the service life of the equipment. Of course The most important point is that wear-resistant ceramic sheets can save energy and reduce emissions, which can effectively reduce energy consumption and facilitate the long-term development of the industry.

To prevent the conveyed material from staying at the bottom of the pipeline, the pneumatic conveying device must keep the material moving at a certain speed. There will be collisions and impacts between the material particles in the transfer and the pipe wall, which is the cause of wear and tear of the conveying pipe in the pneumatic conveying device. The wear in the straight pipe section of the pneumatic conveying pipe is very light. The easy-to-wear parts mainly occur at the bends of the pipes, especially when the solid particles impact the outside of the bends of the pipes, which is elbow wear.   Factors caused by pipe wear 1. Friction or rolling wear: surface wear caused by material friction. 2. Scratch wear: Local peeling occurs due to the material going deep into the surface. 3. Impact wear: The surface tissue is partially broken and detached due to the impact of the material.    The greater the roughness of the elbow, the greater the frictional resistance, and the easier the elbow is to wear. Usually the material with less roughness is selected at the elbow; too many elbows are used. The greater the energy consumption, the easier the pipeline is blocked and the faster the wear of the elbow; the smaller the pipe diameter. The greater the resistance to the airflow. The more damaged the pipe wall; the greater the bending angle. The greater the amount of wear.   The elbow is the most vulnerable part when conveying abrasive materials. When the material passes through the elbow, it hits the inner wall outside the pipe due to centrifugal force and inertia. Some particles slide along the inner wall outside the pipe wall; another part of the particles reflect from the outer inner wall to the inner wall inside the pipe. This repeated movement: the material undergoes several collisions. In the middle of the outer wall of the circular section elbow, a pit like a chisel will be produced. Therefore, the impact and friction of the material on the pipe wall is the main reason for the wear of the elbow.

Alumina ceramics is a widely used type of ceramics, but do you know the production process of alumina ceramics? Powder preparation: According to different product requirements and molding processes, the imported alumina powder is prepared into powder materials. The powder particle size is less than 1 mm. If high-purity alumina ceramics are produced, in addition to the alumina purity of 99, it needs to be ultra-finely pulverized, and the particle size distribution is uniform. In addition, in order to reduce the friction between the powder and the wall, it is necessary to add 1% ~ 2% % lubricant.      Molding method: the molding methods of alumina ceramics include dry pressing, grouting, extrusion, isostatic pressing, injection, casting, hot pressing, etc. In recent years, filter press molding, direct solidification injection molding, gel injection molding, centrifugal grouting and solid-free grouting have been developed at home and abroad. Products of different shapes, sizes, complex shapes, and precision require different molding methods.
