Patch wear-resistant ceramic pipes are mostly used in heavy wear industries such as power plants, steel plants, cement plants, etc., for conveying powders, liquids, gases, etc. There are strict steps and requirements for pasting ceramic sheets on the lining of patch ceramic pipes. Let's talk about the specific methods and precautions of ceramic patches.   Pretreatment work: Before pasting the ceramic sheets, the pipes need to be moved to a suitable location for construction, and the parts to be pasted should be carefully polished. Through polishing, rust, oxide layers and other impurities must be removed until a clean iron surface is exposed, laying a good foundation for subsequent pasting work.   Clean the polished area: After polishing, use a diluent (such as alcohol, acetone, etc.) to thoroughly clean the polished area to ensure that there are no dust, oil, or other impurities on the surface to ensure that the adhesive can fully adhere to the metal and ceramic surfaces. Prepare the adhesive: Prepare the adhesive at room temperature according to the specified ratio (usually 2:1 between the main adhesive and the curing agent). During the preparation process, ensure the adhesive is mixed evenly and free of granular substances. The prepared adhesive should be used within the specified time to avoid premature curing of the adhesive and waste.   Evenly apply the adhesive: During the application of the adhesive, ensure that the application is comprehensive and even. Not only should the polished metal parts be covered, but also the front and four sides of the ceramic sheet should be coated with adhesive. When applying, be careful to avoid the phenomenon of lack of glue or excessive glue.   Paste the ceramic sheet: After the application of the adhesive, the ceramic sheet should be pasted immediately. During the pasting process, use a blade to cut the adhesive paper along the gap of the ceramic sheet to ensure that the adhesive can fully penetrate. Then, use a wooden hammer or other tools to compact the ceramic sheet so that the excess adhesive flows out of the gap. At the same time, ensure that the gaps between the ceramic sheets are also filled with adhesive and evenly applied.   Curing and operation: After the pasting is completed, the pipeline is cured. The curing time is usually 24 to 48 hours, depending on the characteristics of the adhesive and the ambient temperature. After the curing is completed, the pipeline can be put into normal operation.   Throughout the process, it is necessary to strictly follow the steps and requirements to ensure the quality and performance of the wear-resistant ceramic patch pipe. At the same time, it is also necessary to pay attention to the safety and sanitation of the construction environment to avoid adverse effects on construction personnel and the surrounding environment.

Pneumatic ash conveying technology, as the core ash removal method in power plants, chemical plants, and other industries, is of self-evident importance. However, with the increasingly stringent environmental protection and safety standards, and the increase in ash conveying volume due to improved production efficiency, ash conveying pipelines face many challenges. So, what are these challenges specifically? How should we deal with them? Pipeline wear problem Pneumatic ash conveying pipelines are prone to fatigue wear and erosion wear under high-speed, large-flow airflow and dust scouring, and in severe cases, they may even cause pipeline wear. This will not only reduce the conveying efficiency but also cause gas leakage and dust pollution, bringing great inconvenience and safety hazards to production.   Countermeasures: To address this problem, we can choose to use high-hardness, strong wear-resistant pipeline materials or linings. For example, wear-resistant ceramic pipes are an ideal choice. This kind of pipe can effectively resist the scouring of airflow and dust, reduce wear, and increase the service life of the pipe.   Difficulties and maintenance costs of high-altitude operations Due to space and site limitations, many pneumatic ash conveying pipelines are erected at high altitudes. However, the high density and heavy weight of metal pipes bring great difficulties to high-altitude operations and increase maintenance costs. Once the pipes have problems such as wear, maintenance work will become extremely difficult. Coping strategy: If the installation position of the pipe cannot be changed, we can consider using pipe materials with lower density and lighter weight. Alumina wear-resistant ceramic pipes are a good example. Its density is only half that of metals such as steel, which can significantly reduce the difficulty of high-altitude operations and reduce labor costs. In addition, this type of pipe also has strong wear resistance, which can extend service life and reduce maintenance costs.   In summary, by using high-performance materials such as wear-resistant ceramic pneumatic ash conveying pipes, we can effectively cope with the challenges faced by pneumatic ash conveying pipes. This type of pipe can not only improve wear resistance and extend service life, but also reduce the difficulty of installation and maintenance, providing strong guarantees for the production of power plants, chemical plants, and other industries.

In the cement production process, the cleanliness of the boiler heating surface is crucial to maintaining its efficient operation. Ash accumulation not only reduces the output efficiency of the boiler but also increases energy consumption and causes a waste of resources. Therefore, soot blowers play a vital role in cement plants. In particular, air soot blowers, which use high-pressure airflow generated by compressed air, can effectively remove ash accumulation on the boiler heating surface.   However, during the long-term operation of air soot blowers, the air-powder mixture will continuously erode their soot-blowing pipes, resulting in severe wear. To meet this challenge, wear-resistant ceramic sheets are widely used in soot-blowing pipes as anti-wear linings. Wear-resistant ceramics are made of high-purity alumina sintered at high temperatures. They have extremely high hardness and excellent wear resistance, which can significantly extend the service life of soot-blowing pipes. As a professional manufacturer in the field of wear-resistant ceramics, Ibeno produces wear-resistant ceramic sheets with extremely high hardness and smoothness, and the surface has self-lubricating components, making the soot-blowing pipes smoother during operation. The application of this ceramic sheet can not only reduce the erosion and wear of the air-powder mixture on the soot blower, but also improve the overall performance of the soot blower, ensure the cleanliness of the boiler heating surface, and thus improve the output efficiency of the boiler. It is worth noting that the working environment of the soot blower is usually harsh, especially on the furnace wall of the boiler furnace, horizontal flue, and tail flue, where the temperature is high. Therefore, when installing wear-resistant ceramic sheets, choosing a reasonable installation method is necessary to ensure its stability and safety.   The special ceramic adhesive provided by our company can maintain viscosity at a high temperature of 350°C. Still, at higher temperatures, stud welding or dovetail slot installation may be required to ensure the firm installation of the ceramic sheet. The application of wear-resistant ceramic tubes in cement plant air soot blower can not only effectively deal with the erosion and wear of the air-powder mixture, but also improve the overall performance of the soot blower, ensure the cleanliness of the boiler heating surface, and thus improve the output efficiency of the boiler.   As a professional manufacturer in the field of wear-resistant ceramics, Ibeno produces wear-resistant ceramic sheets with excellent performance and stable quality, which are ideal for the wear-resistant lining of cement plant soot blower.

Medium-speed coal mill refers to a coal mill with a working speed of 50-300r/min. It is professional equipment for the preparation and processing of auxiliary materials for blast furnace ironmaking. The medium-speed coal mill can provide suitable auxiliary materials for the blast furnace ironmaking system powder. The medium-speed coal mill is the most important large-scale equipment in the coal-to-oil pulverizing system. Its operating safety and economy are very important for the normal operation of coal-to-oil. Generally, the outlet temperature of the medium-speed coal mill is controlled at 100-120 degrees Celsius.   The materials processed by the medium-speed mill cylinder are particles of various sizes and hardnesses. These materials move inside the medium-speed mill, constantly causing friction, scouring, and impact on various parts of the medium-speed mill body, and body wear is inevitable. The reasons for the wear of the medium-speed mill cylinder are relatively complicated. There are both abrasive wear caused by the sliding of coarse-grained materials, wind erosion wear caused by high-speed scouring of high-concentration dust-containing gases, and impact wear caused by high-speed impact of coarse-grained materials and even foreign objects such as grinding bodies crushed by the mill.   The wear-resistant ceramic sheet of the coal mill cylinder is used to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of linings can also be used to adjust the movement state of the grinding body to enhance the grinding effect of the grinding body on the material, which helps to improve the grinding efficiency of the mill, increase production, and reduce metal consumption. Conventional coal mill linings include wear-resistant ceramic patches and wear-resistant ceramic liners. Especially in the area within 2 meters above the grinding disc, not only is there severe scouring, but there are also large pieces of granular materials hitting it. The traditional anti-wear treatment cannot achieve good results. The area within 2 meters above the grinding disc can be lined with a cemented wear-resistant ceramic lining. This product is made of a unique process and has the characteristics of high hardness and high toughness. At the same time, it changes the traditional pasting installation method and uses adhesive and screws for dual fixing. It is particularly suitable for use in parts with high temperatures and certain impacts.   There are two optional assembly methods for wear-resistant ceramic sheets for the mill cylinder: one is on-site installation, which requires the cylinder to be relatively flat and not uneven; the other is to install the ceramic on a curved steel plate in the factory and then weld it to the cylinder wall. At the bottom of the medium-speed mill cylinder, the impact of coarse particles splashed out by the grinding roller and the scouring of high-temperature and high-concentration powders closest to the static ring are very serious. For the area within 500mm-1500mm of the bottom of the mill cylinder, where the material particles are large, the temperature is high, the wind speed is fast, the wear is large, and the impact is large, composite wear-resistant ceramic lining plates are used. Fix the ceramic to the curved steel plate, the ceramic spacing is zero, the inner wall is smooth, and the service life is extended by about 10 times.

Let's take a deep look at the application of wear-resistant ceramic lining in the wear-resistant discharge chute of the powder selector. Powder selector, as the core equipment of closed-loop grinding system, is widely used in cement production and other powder selection industries, and its stability is directly related to the smooth operation of the entire production line. However, due to the high abrasiveness and humidity of slag, the problems of clearing and replacing worn parts of powder selectors often trouble manufacturers.   To solve this problem, wear-resistant ceramic lining stands out with its unique advantages. This lining is made of microcrystalline wear-resistant alumina, and after high-temperature sintering of more than 1700 degrees, it gives it extremely high hardness and excellent wear resistance. Therefore, it has become an ideal choice for powder selectors in grinding systems in building materials, chemical industries, metallurgy, power plants, mining, and other industries. The installation and replacement of wear-resistant ceramic linings are also very convenient. It is fixed by pasting, which greatly reduces the specifications and quantity of spare parts and saves costs for users. In addition, the surface of the alumina lining is smooth, and it does not scrape or carry materials, which effectively prevents material blockage and makes the clearing work easier.   Wear-resistant ceramic linings have been widely used in many industries, and their unique wear-resistant and anti-blocking properties provide excellent protection for various materials. It significantly reduces the possibility of material blockage, extends the equipment clearing cycle, and reduces the user's downtime and maintenance time, thus bringing real economic benefits to users. This innovative solution has been highly recognized and actively responded to by users.

About the installation of ceramics The wear-resistant ceramics embedded in our company adopt a dovetail groove inlaid structure and are fixed with strong adhesives. Although this process is troublesome to process, it can achieve perfect connection of the ceramic pieces along the gaps in the direction of the dovetail groove.   Since the development of this product so far, no ceramic shedding has occurred. The company has fully considered the volume and weight of the ceramic when designing the ceramic block. Even if individual ceramic pieces are damaged, it will not affect the overall dynamic balance of the impeller.   How to solve the problem of heavy wear and tear? The wear-resistant ceramics produced by our company are one of the most wear-resistant industrial materials currently. They adopt new research results that have won the third prize for scientific and technological progress and have excellent wear resistance. Its core is to control three main factors: raw material selection, powder preparation and sintering; 1. The raw materials are high-purity phase alpha alumina and crystal growth inhibitors; 2. The powder adopts a relatively advanced powder preparation process, and the granulated powder produced is evenly distributed and has good fluidity; ​3. Strict sintering process and precise temperature control. This technology can effectively inhibit the growth of crystals and reduce the generation of internal pores, thereby forming a very dense sinter. The impact of adding wear-resistant ceramics on the overall performance of the impeller The weight of the entire porcelain block is about 58Kg. Excluding the weight reduction of the impeller metal body due to metal material processing, the weight of the entire impeller will increase by about 5Kg compared with the original impeller after the production is completed; Since the shape of the original fan is basically not damaged after the installation of wear-resistant ceramics, the impact on the flow rate of the fan after the installation of wear-resistant ceramics is negligible.   How to solve the problem of ceramic peeling off at high temperatures? The fan impeller runs at a high temperature of 200°C for a long time. Most anti-wear manufacturers use traditional epoxy resin-based organic adhesives. This type of viscose is mainly composed of organic ingredients, is not resistant to high temperatures, and is prone to aging. It cannot meet the requirements of long-term operation. Even if it is installed with dovetail groove or spot welding, once it is operated at ultra-high temperature for a long time, the adhesive will easily age, become brittle and become crushed.   Our company uses adhesive and dovetail slots for double fixation. The high-temperature-resistant inorganic adhesive used has excellent adhesion, processability and thixotropy to steel and ceramics; it can be cured at room temperature; it has a very high Strength and toughness; high heat resistance and aging resistance. This method is mature and reliable. Under the operating temperature of -50℃~500℃, the liner will not age or fall off after long-term operation.   How to solve the problem of fan falling off caused by vibration and transportation? The fan impeller experiences strong vibrations during operation, which requires the adhesive not only to have strong shear strength, but also to have strong earthquake resistance, otherwise the ceramic sheets will peel off under vibration. The adhesive we use has high shear strength (2.5MPa), which can largely protect the ceramic from falling off under strong vibrations.   How to solve the impact of sudden heating and cooling on ceramics during startup or shutdown? When the unit is started or shut down, it will encounter sudden heat and cooling. The thermal expansion coefficients of ceramics and steel are inconsistent. In addition, the organic adhesive is brittle, which can easily cause the entire ceramic to peel off. To address this problem, our company has specially improved the inorganic adhesive so that its thermal expansion coefficient is between steel and ceramics (9×10-6m/m.K). At the same time, the microfiber structure of the adhesive can be well adjusted due to The extrusion of ceramics caused by the inconsistent thermal expansion of ceramics and steel greatly ensures that the ceramics will not fall off during long-term operation in various harsh environments.   How to solve the ceramic gap problem? We use mature technology to ensure that the ceramic gap is no more than 1mm. At the same time, in order to avoid forming a gap along the wind direction and perpendicular to the wind direction, we use the dislocation pasting method to install the wear-resistant ceramics. It can avoid erosion of ceramic gaps along the wind direction and achieve small gap docking.

It is an important public logistics platform for transferring and transporting bulk and groceries in surrounding areas.   Currently, the port mainly loads and unloads ore and ore powder. Due to the highly abrasive nature of the materials and the large transport volume, equipment such as hoppers and chutes are severely worn. Most of the original wear-resistant steel plates wear out after a few months of operation, causing the equipment shell to leak and requiring frequent repairs. This increases the burden of maintenance and seriously affects the normal operation of the equipment and on-site production safety.   Analysis of project-specific situation The chute is severely worn and has been repaired many times. There is no possibility of repairing it again. The following problems exist: 1. Most chutes have small spaces and are very difficult to repair.
