It has extremely high wear resistance, and its wear resistance is more than ten times higher than that of quenched medium carbon steel. Better than tungsten drill carbide.   Corrosion resistance: Ceramic is a neutral material with stable chemical properties, excellent corrosion resistance, and acid resistance, and can resist various inorganic acids, organic acids, organic solvents, etc., and its corrosion resistance is more than ten times that of stainless steel.    Excellent heat resistance: The operating temperature of the on-site equipment must be determined before the construction of the wear-resistant ceramic patch, and the viscose with different temperature resistance should be selected at different temperatures, otherwise the wear-resistant ceramic chip will easily fall off as the temperature rises.  

A wear-resistant pipeline is a composite pipeline with energy saving, emission reduction, wear resistance, and anti-corrosion, which is widely used in electric power, metallurgy, coal, petroleum, chemical, building materials, machinery, and other industries. It can meet the production needs of different enterprises. There are many kinds of wear-resistant pipes in production, and we will introduce them in detail below.   According to the material and forming method of wear-resistant pipes, they are divided into wear-resistant ceramic patch pipes, screw-welded wear-resistant ceramic pipes, integrally formed wear-resistant ceramic pipes, self-propagating composite ceramic pipes, stainless steel wear-resistant pipes, and alloy steel wear-resistant pipes. , Bimetal wear-resistant pipes, high-temperature wear-resistant tortoise shell mesh pipes, high-strength rare earth wear-resistant alloy steel cast pipes, rubber-lined composite steel pipes, wear-resistant backpack composite pipes, etc.    According to other requirements such as industry, conveying medium, working conditions, temperature, pressure, etc. used for wear-resistant pipes, they can be subdivided into the following four categories: Polymer material pipeline: based on polymer compounds (including rubber, plastics, fibers, coatings); Inorganic non-metallic material pipes: non-metallic materials (including glass, ceramics, cast stone, marble) Metal material pipeline: made of metal material; Composite pipes: Made of composite materials, in which one material serves as the base and the other is reinforcement and plays an auxiliary role.   The types of wear-resistant ceramic tubes produced by Yibenuo New Materials are as follows: Centrifugal casting composite ceramic pipes: It is a composite tube of spontaneous combustion high-temperature synthesis and high-speed centrifugation technology. Under the condition of high temperature and high speed, uniform, dense, and smooth ceramic layers and transition layers are formed. At present, it has a good effect in serious wear industries such as straight pipe, elbow, tee, and so on.   All-ceramic lined composite pipes: Due to the high strength, good toughness, good impact resistance, high hardness, wear resistance, corrosion resistance, and heat resistance of corundum alumina ceramics, it overcomes the characteristics of low ceramic hardness, poor wear resistance, and poor ceramic toughness. Therefore, the composite pipe has good comprehensive properties such as wear resistance, heat resistance, corrosion resistance, mechanical shock and thermal shock resistance, and weldability. It is an ideal wear-resistant and corrosion-resistant pipeline for conveying granular materials, grinding, corrosive media, etc.   Adhesive wear-resistant ceramic pipe: It uses adhesive to paste alumina ceramic parts on the inner wall of the pipeline. The production process of this product is simple, the production cycle is long, and the use environment shall not exceed 150 degrees.   Stud welded wear-resistant pipes: The ceramic sheet is pasted on the inner wall of the pipe with high-strength and strong adhesive adhesive, and the ceramic is firmly welded to the inner wall of the steel pipe through small holes. To protect the welding point, the ceramic cap is opened. The production process of this product is more complicated. , the production cycle is long and the cost is high.   One-piece wear-resistant pipes: It is to burn the pipe into a whole and pour it into the steel pipe with a special filler. The inner wall of the pipe fitting is smooth and sealed and has good wear resistance and corrosion resistance. However, this product has a long production cycle and high cost.  

The ceramic-rubber composite plate is a composite wear-resistant ceramic-rubber composite plate of ceramic rubber, which adopts an advanced thermal vulcanization process to vulcanize a square or hemispherical wear-resistant ceramic lining and rubber together.   It combines the advantages of the high hardness of ceramics and the high cushioning and anti-fatigue properties of rubber, and can well solve the problem of equipment wear resistance in the process of conveying large pieces of boring. The addition of rubber not only makes the composite board have good anti-wear and anti-corrosion effects but also can prevent production stoppage and reduce noise caused by material accumulation.    Impact resistance: Alumina wear-resistant ceramic lining rubber has good cushioning performance, which can effectively buffer the impact caused by ores falling from a high altitude, while the wear-resistant ceramic lining plate is resistant to wear because the main raw material of the product is alumina. Performance, but the toughness is insufficient, when the impact reaches a certain level, the wear-resistant ceramic rubber composite plate must be selected.   Convenient construction: there is no gap after the liner is installed. The rubber composite lining can be twisted and cut, suitable for installing various special-shaped equipment.   No sticking and no blocking: Due to the high strength and corrosion resistance of ceramics, the phenomenon of equipment sticking and blocking is effectively solved.   The ceramic rubber composite plate has strong wear resistance, impact resistance, and corrosion resistance. Rubber elastomer has an excellent vibration-damping effect, which can reduce the noise generated during material transportation.   The density of ceramic rubber composite plate is lower than that of steel plate, and its weight is light, because of its high wear resistance, it does not need to be replaced frequently, which saves a lot of time and cost for enterprises.   This product has both the wear resistance of ceramics and the impact resistance of rubber. It is suitable for anti-wear of normal temperature material conveying system equipment. It can withstand a certain impact without sticking to materials and not blocking materials. problems encountered.

Wear-resistant ceramic glue, also known as wear-resistant ceramic adhesive and wear-resistant ceramic adhesive, refers to a high-grade wear-resistant ceramic sheet or lining plate used to paste the wear-resistant ceramic sheet or liner on the surface of the equipment substrate to protect the equipment substrate from wear. Performance adhesive.   It is difficult to realize the connection between the wear-resistant ceramics and the metal parts of the equipment by traditional connection methods such as welding. The use of wear-resistant ceramic glue for bonding to realize the connection between the wear-resistant ceramics and the metal parts of the equipment has been a practice test in recent years. An effective way to connect. After development, this technology has been applied to steel, electric power, metallurgy, mining, cement, port, machinery and other industries and has been widely used and recognized.    Wear-resistant ceramic glue can be used to stick the wear-resistant ceramic sheet very firmly on the surface of the equipment that is severely eroded by the material, prolong the service life of this equipment, and reduce the maintenance of such equipment, so as to reduce the replacement of new equipment and reduce equipment operation and maintenance. The purpose of reducing the production loss of enterprises caused by downtime.   There are many types of wear-resistant ceramic adhesives, and different types of adhesives are suitable for different working conditions. The common types of working conditions are as follows: 1. Equipment washed by ash powder at a temperature below 120°C and equipment subjected to strong erosion or erosion wear of materials 2. Paste the wear-resistant ceramic sheet below 120°C on the top surface and facade of the equipment. 3. It is used to paste the wear-resistant ceramic sheet of the fan impeller. 4. Medium-speed coal mill cones, coarse powder separators, powder discharge fans, coal powder pipes, and other equipment subject to ash erosion, as well as equipment subjected to strong erosion or erosion wear in steel, cement, chemical, and other industries.   The amount of wear-resistant viscose depends on the thickness of the ceramic sheet, and the thicker the ceramic sheet, the more viscose is used. The thickness of the ceramic sheet is 10-30mm, the amount of viscose per square is about 2-2.5kg, the amount of viscose per square of 8-10mm is about 1.5-2kg, the size of the ceramic sheet is less than 6mm, the amount of viscose per square is 1-1.5 kg. It is not that the more glue is used, the better the pasting. On the contrary, the overflow of glue between the ceramic sheet and the ceramic sheet due to the excessive amount of glue will seriously affect the use effect of the ceramic sheet, and will seriously affect the falling off.

Roller ceramic lagging is an important part and component of the belt conveying transportation system. The lagging drum can effectively improve the operation of the conveying system and protect the metal drum from being worn. The lagging surface of the ceramic rubber sheet can increase the size of the rubber sheet. The surface friction force can effectively prevent the sliding friction between the drum and the belt, reduce the slippage of the belt, and reduce the material adhesion on the surface of the drum, thereby reducing the deviation and wear of the belt, improving the operation efficiency, and making the drum and the belt run synchronously. To ensure the efficient and large-capacity operation of the belt. They are widely used in power plants, coal mines, cement plants, steel, metallurgy, coal, fertilizer, grain depots, ports and other industries.    The drum is the main component for transmitting power. The rubber-coated drum of the belt conveyor generally conveys the mixture of bulk materials (ore, coal), and the equipment operates continuously for a long time, which requires the drum to have high wear resistance, extremely high tensile strength, and resistance to tear properties. The drum is also susceptible to weather (eg rust, sludge) if operated in the open air. The traditional rubber roller is easy to wear, slip, and run, and damage the conveyor belt, resulting in a decrease in the conveying load of the belt conveyor and frequent equipment replacement.   When the drum drives the belt conveyor, it is necessary to increase the friction between the mechanical transmission conveying and the surface of the drum to reduce the mutual wear of the conveyor belt when the surface of the drum slips, provide stable running traction and prolong the service life of the belt and drum.   The wear-resistant ceramic lagging developed by our company is made of corundum ceramic embedded on the surface as the anti-wear layer, and polyurethane, which is famous for wear-resistant rubber, as the vulcanized layer, and then bonded with imported high-strength adhesive. The service life is more than 10 times that of rubber-coated rollers.

Among many coal preparation technologies, the dense medium cyclone coal preparation technology using centrifugal force separation is the most efficient one in the current gravity coal preparation methods. Therefore, it is very important to improve the wear resistance of the heavy medium cyclone in the main washing equipment and prolong the service life of the cyclone. The use of alumina wear-resistant ceramic liner can improve the wear resistance of the heavy medium cyclone.   Wear-resistant ceramic liner is a popular high-performance ceramic, which is widely used in various fields due to its high-cost performance. Combined with the current market demand for coal preparation, it is more suitable to use alumina ceramics as wear-resistant linings for heavy medium cyclones, which can basically meet the requirements of the wear conditions of intermediate cyclones and meet the current actual situation.    The reason why the wear-resistant ceramic liner has such an effect is that the wear-resistant ceramic liner has high-temperature resistance, wear resistance, corrosion resistance, shock resistance, thermal expansion, and contraction resistance, and can also exert high strength and high toughness. Features, through the integrated design, can be easily replaced and installed.   The wear-resistant ceramic liner can work for a long time without falling off. It can run in an environment of 500 degrees Celsius for a long time, and the general working conditions can meet such temperature conditions; under the same conditions, the wear-resistant ceramic lining plate is 10 to 20 times more wear-resistant than ordinary pipes.   The hardness of wear-resistant ceramic products is second only to diamond in the world, which is beyond the reach of wear-resistant steel and stainless steel products. Wear-resistant ceramics are pasted with high-strength ceramic structural adhesive, which ensures long-term operation under high-speed rotation and does not fall off, and ensures the service life of the product.

Alumina ceramic pipes can be divided into two types: ceramic patch and ceramic overall ceramic ring. Let's take a look at how to correctly choose these two wear-resistant ceramic pipe processes. Ceramic patch wear-resistant ceramic pipe Ceramic patch wear-resistant pipeline uses high temperature resistant strong adhesive to paste alumina or zirconia wear-resistant ceramic sheet on the inner wall of the pipeline, and then heat and solidify to form a firm anti-wear layer. Ceramic patch pipes have excellent wear resistance, corrosion resistance, heat resistance, and other properties. The price of wear-resistant ceramic pipes with ceramic sheets is relatively affordable, and the wear resistance is also very good. It is generally used for large-area construction, and pipes can be pasted regardless of size. The construction speed is fast, the production process is relatively simple, and the production cycle is short. , The cost is relatively low, mainly used in tailings transportation, slag transportation, coal powder transportation, river sand transportation, dust removal systems, slag transportation, slag transportation, ash discharge systems, etc.    Ceramic ring wear-resistant ceramic pipe A pipelined ceramic ring, also known as a one-piece ceramic pipe, is assembled by pouring wear-resistant ceramic pipe fittings into the steel pipe with special filler after the whole is fired. The inner wall of the pipeline is smooth, the sealing performance is good, and it has good wear resistance and corrosion resistance. Compared with ceramic patch pipes, the overall ceramic ring lined with ceramic pipes will be more expensive. The advantage is that the thickness can be made very thick, and its comprehensive service life is relatively high, and it will not be affected by temperature. If your budget is relatively large, And if you want to use it for a long time without any major problems, you can choose this type of ceramic pipeline, which is mainly used in the lithium battery industry, river sand transportation, tail gas treatment, limestone transportation, coal powder transportation, mineral powder transportation, Cement delivery.

Due to the drop of the material and the high hardness of the particles in the chute, it causes great wear and tear on the chute, and the lining plate needs to be replaced frequently. The core element that determines the performance and service life of the chute is the chute liner.   The chute needs to transport materials frequently, with large impact force and strong friction force, which requires the lining plate to have strong impact resistance and wear resistance. To ensure that the chute is not blocked or hung, we also need to ensure that the surface of the liner is smooth. This makes the impact-resistant, wear-resistant and smooth surface wear-resistant ceramic lining the best choice for coal preparation chutes.    The wear-resistant ceramic block is dislocated and bonded to the inner wall of the chute with high temperature resistant inorganic adhesive. The ceramic adopts the dislocation bonding process, and there is no linear gap along the medium flow direction, which effectively avoids the erosion of the ceramic gap by high-speed materials.   In the process of using wear-resistant ceramic liners, we also need to choose different models and installation methods according to different environments such as the temperature and location of the liners, and use them flexibly to improve performance and save costs.

The wear-resistant ceramic pipe, the full name of the metal-ceramic lined composite pipe, is a new type of wear-resistant pipe that uses a special process to firmly combine the ceramic and the metal pipe, and uses the high strength and high hardness of the wear-resistant ceramic to increase the wear resistance and service life of the pipe.   The inner lining layer of the wear-resistant ceramic pipe is a new type of ceramic such as alumina ceramics, which has high hardness, high temperature resistance and excellent corrosion resistance. leap.    Compared with traditional wear-resistant pipes, wear-resistant ceramic pipes also have significant advantages such as lightweight and convenient installation.   Alumina wear-resistant ceramic pipes are widely used in wear-resistant pipes. Alumina wear-resistant ceramics are used as the inner lining of the pipes, which have the characteristics of wear resistance, corrosion resistance, impact resistance, smooth inner wall, and not easy to accumulate materials. The wear-resistant ceramic pipeline is a kind of wear-resistant pipeline with high-cost performance among wear-resistant ceramic pipelines. It is often used in equipment with serious impact and wear to transport bulk materials, powders, gases, slurries, and other media, with very strong applicability. , the use is also very wide, favored by major enterprises.   Today's wear-resistant ceramic tube technology has matured. According to different user requirements, SMD wear-resistant ceramic tubes, spot-welded cassette wear-resistant ceramic tubes, integrated wear-resistant ceramic tubes, centrifugal casting composite ceramic tubes, etc. have been derived. Many types. It has been widely used and highly recognized in thermal power, metallurgy, steel, coal, cement, chemical, and other pneumatic powder conveying industries.
