There are many types of wear-resistant pipes on the market, with different performances and different application ranges. Today we understand the difference between wear-resistant ceramic pipes and ordinary pipes.   First of all, compared with ordinary pipes, wear-resistant ceramic pipes are inherently corundum ceramics, and their life can be extended the most during use, generally ten times or even dozens of times that of ordinary steel pipes. Many people are listening After that, there will be signs, then the cost of using this kind of pipeline will be very low. Of course, because its service life is longer, so we can get the maximum savings in the economic cost that we are most concerned about.   Secondly, because the inherent alumina ceramic is not afraid of high temperatures, it can have a certain degree of heat resistance during use, so it has more space and ductility for the working environment of the equipment and the nature of the work.   Finally, the wear-resistant ceramic pipes produced by Ibeno are mainly ceramic-lined elbows, straight pipes, and tee-lined wear-resistant ceramics. The steel parts are made of integral hot-bent seamless steel pipes, which are better than the piping technology of the shrimp joints. The service life is longer, and there is no need to worry about any problems in the process of use. Because of the various advantages of wear-resistant ceramic pipes, many factories and companies will prefer this product, and we use it After this kind of pipeline, the greatest savings can be achieved in terms of engineering cost.

During the long-term operation of the belt conveyor, problems such as normal or unexpected wear and aging will occur, leading to failures and directly affecting the normal operation of production.   Roller encapsulation is used to increase the friction coefficient between the conveyor belt and the surface of the roller during transmission, reduce the mutual wear between the conveyor belt and the surface of the roller, improve the traction of the operation, and extend the service life of the conveyor belt and the roller. The rubber on the surface of the drum can effectively improve the operation of the conveyor system, prevent the conveyor belt from slipping, and make the drum and the belt run synchronously, thus ensuring the belt's efficient and large-volume operation.   The drum encapsulation can also effectively prevent the sliding friction between the drum and the belt, reduce the material adhesion on the surface of the drum, and reduce the deviation and wear of the belt. Roller ceramic encapsulation is the use of advanced thermal vulcanization technology to vulcanize wear-resistant ceramic blocks with particles on the surface in a special rubber according to a certain layout. The bottom layer of the rubber sheet is a CN layer, and then a special adhesive is used to paste it on the surface of the roller instead. Traditional rubber can enhance the friction coefficient between the belt and the drum and increase the service life of the drum. At the same time, the regularly distributed ceramic grooves are convenient for draining mud, ensuring normal operation in harsh environments, and increasing the friction coefficient of the roller surface, reducing the probability of slippage of the conveyor belt. The life of ceramic encapsulation is 5-10 times longer than that of ordinary encapsulation, which reduces the trouble of maintenance and improves the operating efficiency of the enterprise.   The thickness of the roller ceramic encapsulation is 12mm, 15mm, 16mm, 20mm, and the length is 1200mm, 1400mm, 1600mm, 1800mm, 2000mm. It can be installed on-site. The roller does not need to be disassembled, convenient and fast. It is suitable for rollers of various specifications and extreme harshness. Roller in the working environment.  

Types of wear-resistant ceramic composite pipes: Direct adhesive ceramic composite pipe: Direct adhesive ceramic composite pipe uses high temperature resistant strong adhesive to paste alumina ceramic sheet on the inner wall of the pipe, and forms a firm anti-wear layer after being heated and solidified. The production process of this kind of product is relatively simple, the production cycle is short, and the cost is relatively low. Hunan Ibeinuo New Material Co., Ltd. produces various types of patch wear-resistant ceramic pipes, which can also be customized according to customer needs. Direct adhesive ceramic composite pipes are not limited by pipe size, ranging from 1 inch to 120 inches in diameter, and even larger sizes can also be customized.   Spot-welded clip-on wear-resistant ceramic pipes: spot-welded clip-on wear-resistant ceramic pipes are made by using high temperature resistant strong adhesive to paste an alumina ceramic sheet with a hole in the middle on the inner wall of the pipe. At the same time, the ceramic is firmly welded to the inner wall of the steel pipe. To protect the solder joints, a ceramic cap is screwed on. Each piece of porcelain is not only pressed and inserted into each other, but each piece of porcelain forms a trapezoidal angle so that the tiles are tightly connected and there is no gap; when the last piece of a circle is tightly embedded, a 360° mechanical freedom is formed between the tiles. Locking force (this technique was used in Chinese bridge construction projects centuries ago). The production process of this kind of product is relatively complicated, the production cycle is long, and the cost is high.   One-piece wear-resistant ceramic pipe: The full name of one-piece wear-resistant ceramic pipe is ceramic-lined composite steel pipe, which is assembled by pouring the ceramic pipe fittings into the steel pipe with special fillers after firing them as a whole. The pipeline has a smooth inner wall, good sealing performance, and good wear resistance and corrosion resistance. However, this kind of product has a long production cycle and high cost.   Sintered ceramic composite pipe: Centrifugal casting composite ceramic pipe is also called sintered ceramic composite wear-resistant pipe. It is a composite pipe manufactured by "self-spreading high-temperature synthesis-high-speed centrifugal technology", which forms a uniform, dense, and smooth surface ceramic at high temperature and high-speed Layer and transition layer. Because the production process is simple and the cost is low, it is suitable for long-distance transportation of powder, but its wear resistance is slightly worse than that of conventional wear-resistant ceramic pipes. It is generally used as a straight pipe.   Summary: The composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock resistance and thermal shock resistance, and good weldability. It is an ideal wear resistance and corrosion resistance for conveying granular materials, grinding, corrosive and other media Pipelines can be widely used in electric power, metallurgy, mining, coal, chemical and other industries.  

The ceramic liner is a material with alumina as the main body, with a unique design and a good buffer layer, which can resist the impact of bulk materials. The following aspects need to be paid attention to. 1. Before installing the ceramic liner, it is necessary to be familiar with the operating procedures of the relevant equipment used in the work and the safety production specifications at the construction site. 2. Cut off the start-up power of the construction equipment, and hang up a warning sign of "Manned operation, no closing". 3. The ceramic liner can only operate after confirming that the gas and dust content is within the safe value range, otherwise accidents may occur. 4. If the equipment is underground or in a confined area, it is necessary to test the gas and dust content before using the cutting torch or electric welding. 5. After the ceramic liner installation is completed, the tools, ironware, welding slag, etc. in the installation area should be cleaned up.    

Wear resistant ceramics are more expensive than other wear-resistant materials in people's impression. Now we will elaborate on this issue.   The price of wear-resistant ceramic pipes needs to be different according to the specifications and models of the wear-resistant ceramic pipes and the selected alumina wear-resistant materials.   1. Commonly used paste type (patch type) ceramic pipes, φ219 pipes are lined with alumina corundum ceramics, the price of 1 meter in length is about RMB 1,000, and the service life can reach 3 when the working environment is not bad. Over years, it is a wear-resistant pipe with very high cost performance.   2. The smaller the diameter of the wear-resistant ceramic pipe, the more complicated the process of lining wear-resistant ceramics, and the higher the labor and machine costs; the smaller diameter pipes are recommended to use wear-resistant ceramic rings instead of wear-resistant ceramic sheets as wear-resistant Lining material.   3. The price of overall wear-resistant ceramic pipes> the price of welded wear-resistant ceramic pipes> the price of patch wear-resistant ceramic pipes.   4. In terms of the selected wear-resistant materials, the price of zirconia wear-resistant ceramic sheets> the price of alumina wear-resistant ceramics. The higher the purity of the alumina wear-resistant ceramics, the more expensive the price.   5. Generally speaking, the price is related to many factors of wear-resistant ceramic pipes. It is necessary to match suitable pipes and wear-resistant materials according to the on-site use conditions of the pipes to achieve the best cost performance!  

The wear-resistant ceramic sheet has a higher hardness and is a material second only to diamond. Its wear resistance and pressure resistance are also very strong, even in the working environment of high pressure, high temperature or strong friction, the wear-resistant ceramic sheet will not be severely damaged.   The wear-resistant ceramic sheet is a special corundum ceramic made of Al2O3 as the main raw material, rare metal oxides as the solvent, and calcined at a high temperature of 1700°C. Wear-resistant ceramic sheets have many aliases due to different regions and habits, such as ceramic sheets, linings, ceramic mosaics, alumina linings, and high-aluminum linings.   Wear-resistant ceramics have the characteristics of wear resistance, impact resistance, corrosion resistance, high temperature resistance, and convenient construction. They are used as materials in electric power, metallurgy, coal, petroleum, cement, chemical, machinery and other industries (such as ash, coal powder, mineral concentrate, Tailings, cement, etc.) is an ideal material for the surface of conveying equipment, which is very safe and reliable to use under high temperature corrosion, high temperature wear or high temperature corrosion. Data show that the life of wear-resistant ceramics is ten to twenty times longer than that of cast stone, wear-resistant alloy cast steel, steel plastic, steel rubber and other materials.   With the advent of China's industrialization era, wear-resistant ceramics have added more high-tech, making wear-resistant ceramic sheets more popular in China's industrialization field. In addition to the above advantages, the wear-resistant ceramic sheet has strong pressure bearing capacity, and the wear-resistant ceramic sheet will not be broken under strong pressure; the wear-resistant ceramic sheet is light in weight, which can greatly reduce the weight of the equipment.   Experts expect that the market demand for wear-resistant ceramic sheets and other wear-resistant accessories will see a steady growth in the future, and the wear-resistant accessories industry will also usher in a period of continuous development. Manufacturers of wear-resistant ceramic sheets must seize development opportunities to seize the domestic and foreign markets with more complete products, excellent quality, and more advantageous prices, thereby increasing their share of the wear-resistant market.  

As a new type of material, alumina ceramics have excellent properties such as high mechanical strength, low specific gravity, low abrasion, high-temperature resistance, and high electrical resistance. It is applied and promoted in various industries and has a huge market prospect. According to alumina content, alumina wear-resistant ceramics are divided into ordinary type and high-purity type. High-purity alumina ceramics mean that the content of AL2O3 in the material is above 99.9%; ordinary alumina ceramics are divided into 99 porcelain, 95 porcelain, 92 porcelain, 90 porcelain, 85 porcelain and so on. Our company produces and sells mainly 92 porcelain and 95 porcelain.   At present, in the international market, Japan’s precision ceramics have a large share of the international market, and ceramic components in petrochemical, food engineering, environmental engineering, electronic industries, and other industries have developed rapidly; Electronic ceramic components are widely used in the fields of manufacturing, industrial manufacturing, energy, transportation, aerospace and military; European countries mainly focus on the application of alumina ceramics to ceramic piston covers, turbochargers and other power generation equipment; and the application of alumina ceramics in China The most widespread industries are textile, petroleum, chemical, construction, and electronics industries.   Most of China's alumina ceramic enterprises are private enterprises, limited by funds and talents, and their R&D and innovation efforts are weak. With the country's strong support for new industries in recent years, the alumina ceramic industry will have huge development potential in the fields of aerospace, power electronics, and medical equipment.

As we all know, roller encapsulation is a necessary link before the roller is put into use. The roller encapsulation can protect the roller from corrosion and abrasion, increase the friction of the belt, and extend the service life of the conveying system. At present, ordinary wear-resistant rubber sheets can no longer meet the harsh transportation environment. Due to their limited cleaning ability, the friction between the drum and the belt drops sharply, and excessive wear of the rubber sheets and belt slippage will occur. The method of covering the ceramic rubber sheet can effectively improve the operating conditions of the conveyor system, protect the metal roller from being worn, prevent the conveyor belt from slipping, and make the roller and the belt run synchronously, so as to ensure the efficient and large-volume operation of the belt. The ceramic rubber sheet coating for the drum has the following advantages: 1. The ceramic rubber sheet produced by Ibeno is embedded with 92% alumina ceramic block in rubber. The high abrasion resistance of the ceramic on the rubber surface increases the friction coefficient between it and the belt. The friction coefficient is 4-6 times that of ordinary rubber sheets, which can significantly reduce the occurrence of belt slippage.   2. The combination of ceramic and rubber sheet greatly increases the wear resistance of the rubber sheet, which is 8-10 times higher than that of the high wear-resistant rubber sheet.   3. The special arrangement of ceramic blocks and rubber ensures that the drum has better drainage and mud discharge performance after rubber coating.   4. The bottom of the ceramic rubber sheet is equipped with a semi-vulcanized CN layer, which works with imported adhesive to achieve strong adhesion between the rubber sheet and the surface of the roller.   5. The roller encapsulation construction can be carried out on site, which is convenient, quick and cost-effective.   The method of encapsulating the ceramic rubber plate roller: 1. Glue shoveling: Determine whether it is necessary to shovel the glue according to the condition of the residual glue on the surface of the drum. If the residual glue exceeds 0.5m, the glue shoveling machine must be used to remove the residual glue. Before shoveling rubber, it must be ensured that the roller can be rotated manually. If it cannot be rotated, the connecting pin between the roller and the reducer must be removed. If the residual glue area is less than 0.5m, there is no need to shovel glue.   2. Polishing: There are many dirt, dust, grease, water, rust and other organic or inorganic pollutants on the metal surface, which affect the wetting of the glue. In order to improve the bonding strength, the surface of the metal roller needs to be polished to expose the original metallic luster.   3. Cleaning: There are many dirt, dust, grease, water, rust and other organic or inorganic pollutants on the polished surface, which will affect the wetting of the adhesive. It is necessary to use cleaning agents to remove surface dirt and deep clean the entire drum surface to prevent various impurities from affecting the glue bonding effect.   4. Transition: Use a brush to apply a layer of metal treatment agent evenly and quickly on the cleaned metal surface. It is required to apply evenly and completely without any leaks, and let it dry completely for about one hour. The metal primer can effectively prevent the surface contamination of the roller and prolong the storage period of the processed metal. It can also ensure the wettability of the adhesive and increase its adhesive strength and durability.   5. Glue: mix and stir the two components of the adhesive. According to the needs, you can take a part of the glue and mix it in the container according to the ratio of 100:4. The glue after preparation must be used in time, not for a long time. The roller needs to be painted twice. After the first pass, wait 10-25 minutes for it to dry before applying the adhesive for the second time. Brush the ceramic rubber plate with CN layer once.   6. Laminating: Determine the bonding datum line on the surface of the drum: After brushing the glue for the second time, find the datum of the ceramic rubber sheet on the surface of the drum, find the position and perform the bonding. After lamination, use compaction rollers to push from the middle of the roller to both ends.   7. Sealing: The first job is to repair the edge of the drum, and use a rubber hammer to intensively beat both sides from the middle to the sides, and wait for natural drying.  

The wear-resistant elbow of the powder feed pipe mainly starts from the air box at the outlet of the pulverized coal mixer and the powder exhaust fan to the burner and the tertiary air outlet and connects the recirculation air duct from the outlet air box of the powder exhaust fan to the inlet of the coal mill. The elbow part in the pipeline, because it mainly transports solid powder media, has relatively strong abrasion strength. The selection of wear-resistant materials for the powder-feeding pipeline wear-resistant elbow should have high toughness and impact resistance, high hardness and cutting Strong wear-resistant ceramic material.   The wear-resistant elbow of the powder-feeding pipe is lined with wear-resistant ceramic material. The wear-resistant performance of the powder pipe is very good, the hardness reaches about HV1800, and the wear resistance is more than 10 times that of ordinary steel; it also has good Impact resistance, even in harsh working conditions, you can easily face it; corrosion resistance is also particularly good, after lining wear-resistant ceramics, it will not react with acid and alkali, and will not be oxidized, resulting in The rust is mixed into the pulverized coal, causing incomplete combustion.   The use of wear-resistant ceramics as wear-resistant materials for powder-feeding pipe wear-resistant elbows is the most cost-effective choice. Wear-resistant ceramics can make the inner wall of the pipe very smooth and smooth without causing powder bulk material. The use effect is very good. The service life is very long, generally about 10 times that of ordinary elbows. Wear-resistant ceramics are currently one of the most popular wear-resistant materials for powder-feeding pipe wear-resistant elbows.  

The wear-resistant pipe is used for the serious part of the engineering wear, and the internal addition of a composite pipe of the wear-resistant layer is added to energy conservation and emission reduction, wear-resistant and anti-corrosion.   Depending on the abrasion conditions, there are also different material selections on the wear-resistant pipeline liner. Continuous wear-resistant ceramic pipe (liner differential aluminum, silicon carbide, boron nitride, etc.), abrasion-resistant alloy tube, turtle-resistant mill, wear-resistant cast stone tube, self-propagating composite pipe, etc. Wear-resistant ceramic composite pipes with conventional steel pipes, wear-resistant alloy cast steel tubes, cast stone tubes, and self-propelled tubes. The outer layer of the wear-resistant pipe is a seamless steel pipe, and the inner layer is corundum ceramics. The hardness of the corundum is up to HV1100-1400, and wear resistance is 20 times higher than the carbon steel tube. Wear-resistant pipeline anti-wear is mainly against the inner lining of alumina ceramics.   Wear-resistant ceramic composite pipelines quickly occupy the market, in addition to high quality, and good performance, but also its performance ratio is higher than other wear-resistant pipes. In terms of wear-resistant pipelines of the same specifications and unit lengths, the wear-resistant ceramic composite pipe weight is only about one or more of the wear-resistant alloy casting steel pipe, and its project cost is reduced by 20% -30%.   The wear-resistant ceramic composite tube is a corundum ceramic (A-Al2O3), Moh's hardness can reach 9.0 equivalent to HRC90 or more, the wear-resistant life is ten times more than ten times, and the inner surface is smooth, which is small. The weight of the pipe is light, the welding performance is good, which can be welded, flange fast linkages, etc., the construction is convenient, and the installation fee can be reduced.
