The wear resistance of wear-resistant ceramic linings is widely recognized, and adhesive wear-resistant ceramic linings are widely used due to the advantages of easy installation, low cost, and saving maintenance time. However, in power plants and metallurgical plants, the temperature of equipment is generally high, and conventional wear-resistant ceramic adhesives are not resistant to high temperatures. Once operated under ultra-high temperature for a long time, the adhesive is easily aged and causes ceramics to fall off.    High temperature wear-resistant ceramic adhesive is AB double-group epoxy adhesive; white paste, can be cured at room temperature, heating and curing can obtain better bonding strength; long-term temperature resistance after curing 250 ° C, high-temperature resistance 280 ° C, aging resistance , Corrosion resistance, high strength, good toughness, strong adhesion, optimize the construction process and reduce construction costs. Commonly used for self-adhesion and mutual adhesion of metals, cement, ceramics and other materials, especially suitable for sticking wear-resistant ceramic sheets (linings) on the surface of equipment below 250°C. Such as the pasting of wear-resistant ceramic sheets at the outlet pipe of coal mills in thermal power plant, inner shell of powder discharger, dust removal system in steel plant, elbow of air duct, etc.

The wear resistance of the wear-resistant ceramic tube mainly depends on the wear resistance of the wear-resistant ceramic lining, and the wear resistance refers to the ability of the material to resist mechanical wear, which is mainly determined by the hardness, strength, and roughness of the material.   1. Hardness: The hardness of the material reflects the ability of the material to resist the material being pressed into the surface. The higher the hardness, the shallower the depth of the material intrusion, the smaller the volume of wear, and the higher the wear resistance. The alumina content of wear-resistant ceramics exceeds 92%, and the hardness reaches above HRA85, which is the basis for wear-resistant wear-resistant ceramic pipes.   2. Strength: With high strength, it can provide good support for resisting wear and give full play to the ability of anti-wear hard to resist wear, that is to say, strength and hardness complement each other. The flexural strength of wear-resistant ceramics reaches 300-450Mpa, and the compressive strength is as high as 1200-2500Mpa, which further strengthens the wear resistance of wear-resistant ceramic tubes.    3. Roughness: The smaller the roughness value, the higher the fatigue and wear resistance. The surface roughness of the ceramic has a certain relationship with the thickness of the powder particles under certain conditions. The wear-resistant ceramics have been ground and polished many times, and they are supported by high-quality fine powder. The smoothness is very high, which adds a third guarantee for the wear resistance of the wear-resistant ceramic tube.   4. High hardness, high strength, and smooth surface are the reasons for the wear resistance of wear-resistant ceramic tubes. On this basis, there are also integrated molding, staggered joints, etc. to reduce the erosion of wear-resistant ceramic tubes by gas and powder, so that The wear resistance of wear-resistant ceramic tubes has reached a new level.  

Wear-resistant ceramic pipes are different from ordinary steel pipes. The inner wall of wear-resistant ceramic pipes has wear-resistant ceramics as a wear-resistant layer, and wear-resistant ceramic adhesives are used to connect the wear-resistant layer and the steel wall. Steel pipes are different. Because welding will release a lot of heat in a short time and generate local high temperatures, the edge of ordinary steel pipe can usually be welded directly, but if the wear-resistant ceramic pipe is directly welded, the internal porcelain will be blackened, and part of it will be melted due to the high temperature released. Viscose causes the internal wear-resistant ceramic to peel off.    How to weld wear-resistant ceramic pipes? Under normal circumstances, before welding wear-resistant ceramic pipes, a welding space should be reserved when applying porcelain, and then normal welding is performed. After the welding is completed, wait for the pipes to cool down, and then clean up the welding slag and paste the remaining parts of the pipes.

The ceramic rubber lining 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 high hardness of ceramics and high cushioning and anti-fatigue properties of rubber, and can well solve the problem of equipment wear resistance in the process of conveying bulk materials. 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.    1. 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 insufficient toughness, wear-resistant ceramic rubber composite plate must be selected when the impact reaches a certain level   2. Convenient construction: there is no gap after the lining is installed. The rubber composite lining can be twisted and cut, suitable for installing various special-shaped equipment   3. 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 traditional nylon board is often stained, which affects the work efficiency   4. The ceramic rubber composite plate has strong wear resistance, impact resistance, and corrosion resistance.   5. The density of ceramic rubber composite plates is lower than that of steel plates, and their 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 material conveying system equipment at room temperature. It can withstand a certain impact without sticking and blocking materials.  

Special ceramics refers to ceramics with special mechanical, physical, or chemical properties, which are used in various modern industries and cutting-edge science and technology. The raw materials used and the required production technology have been greatly different and developed from ordinary ceramics. The country calls it "fine ceramics", and recently our country's material experts agreed that it is called "advanced ceramics". Special ceramics can be subdivided into structural ceramics, functional ceramics, and tool ceramics according to their performance characteristics and uses.    Different raw materials: In terms of raw materials, it breaks through the boundaries of traditional ceramics with clay as the main raw material. Special ceramics generally use oxides, nitrides, borides, carbides, etc. as the main raw materials.   The composition is different. The composition of traditional ceramics is determined by the composition of clay, so ceramics from different origins and kilns have different textures. Since the raw materials of special ceramics are pure compounds, the ingredients are determined by artificial proportions, and their properties are good and bad. The purity and craftsmanship of the raw materials are not affected by the origin.   Different structures: traditional ceramics have many impurities and pores, while special ceramics have excellent properties in terms of hardness, strength, corrosion, and wear.   The production process is different: it breaks through the boundaries of traditional ceramics and kilns as the main production methods and widely adopts vacuum sintering, hot pressing, isostatic pressing, and other methods.   Different properties: traditional ceramics are mainly based on life, and special ceramics have different special properties and functions, such as high strength, high hardness, corrosion resistance, electrical conductivity, insulation, as well as in magnetism, electricity, light, sound, biological engineering, etc. It has special functions so it has been widely used in high-temperature, machinery, electronics, aerospace, and medical engineering.  

As we all know, the recent oil price has been soaring. The reason why the oil price is soaring is mainly due to changes in market industry factors. The skyrocketing oil price also drives the cost of other industries to increase. The price of our wear-resistant ceramic series products is also the same. The price of steel keeps rising, the cost of steel purchased by manufacturers is also rising, and the price of our products also rises slightly. Yibeinuo New Materials is a factory specializing in the production of wear-resistant ceramics. The price of steel has had its supply channels for many years. No matter how the price of steel rises, we will serve customers with fair and reasonable prices, and will never deliberately drive up prices.   As a manufacturer, we give the direct ex-factory price. If there is a need to purchase wear-resistant ceramic series products, it is recommended to buy them early.    

Alumina wear-resistant ceramic sheets are currently in demand in the market, and everyone is more concerned about the service life of alumina wear-resistant ceramic sheets. Generally, how long can the ceramic wear-resistant sheet of this material be used? Today I will introduce it to you.   To understand the service life of alumina wear-resistant ceramic sheets, we must first understand the wear mechanism. The wear of alumina wear-resistant ceramic sheets can be roughly divided into cutting wear, fatigue wear, abrasive wear, Impact wear, etc. Due to the different working principles of each type of wear, the wear mechanism of ceramic sheets is also very different. In practical applications or experiments, they are often not isolated, but interconnected ties, and interact with each other.   The service life of alumina wear-resistant ceramic sheets is not only related to its quality, but also external factors, mainly including the size of medium particles, hardness, friction mode, environment, load, flushing speed, temperature, and time.   Generally speaking, the smaller the particles, the lower the concentration, the lower the scouring speed, the smaller the scouring angle, and the longer the service life of the alumina wear-resistant ceramic sheet. Usually in the network pipe of the slag micro powder production line, the surface area of the micro powder is 420~450m2/kg, the concentration is 350a/Nm3, the speed is 28~30m/s, and the flushing angle is 30, the 20mm wear-resistant ceramic sheet can be used for 8~10 years. Raw and clinker grinding materials are easier to grind than slag, and the service life of alumina wear-resistant ceramic sheets with the same thickness can reach more than 10 years.

The global economy has ushered in the outbreak of the new energy industry, and the demand for ceramic transportation pipelines has increased sharply. In the lithium battery cathode material production line, from raw material delivery, feeding, batching, mixing, and sintering (including secondary or tertiary sintering) to final packaging, Each link is connected by pipes to form a closed conveying system, so the amount of pipes is large. In the early days, PU pipes, rubber pipes, and stainless steel pipes were usually used. Compared with traditional metal pipes, ceramic lined pipes have been widely used in the lithium battery industry because of their super wear resistance, high-temperature resistance, acid and alkali corrosion resistance, and other characteristics. application.   It has been 30 years since lithium battery products were born in the early 1990s. In recent years, with the rapid expansion of my country's 3C market and the new energy vehicle market, Chinese enterprises have risen rapidly, breaking the pattern of competition between Japan and South Korea, and occupying the world's largest scale. In 2016, China accounted for 15 of the top 20 lithium battery manufacturers in the world. By 2019, CATL, BYD, etc. have ranked among the top in the world in terms of shipments. Around the upstream and downstream of lithium battery manufacturers, a huge and complete industrial chain has already been formed in China.    In the past three years, the rapid development of the domestic new energy vehicle industry has put forward higher requirements for the safety performance and energy density of battery materials, and high nickel ternary has become mainstream. Compared with traditional cathode materials such as lithium iron phosphate, high nickel ternary materials have higher hardness, higher requirements for wear resistance of pipelines, and stricter demagnetization (no copper, iron, and zinc). Some manufacturers continue to use the FRP liner, tetrafluoro liner, and even tungsten carbide spray pipe used in the lithium iron phosphate preparation system, but they find that the service life is extremely short after use.   Integral wear-resistant ceramic lined pipes have 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 nonmetallic lining material with ultra-high hardness, the ceramic-lined elbow can effectively block harmful substances such as powder and iron. The contact of substances reduces the content of impurities such as iron in the positive electrode material, thereby improving the safety performance of the battery.   The integral wear-resistant ceramic tube steel is made of 304 stainless steel integrally formed (hot simmering, non-straight tube welding), lined with 92～95 high purity alumina ceramic tube with stable performance, and filled with special viscose for ceramic and steel tube layer ceramics. Different from the general ceramic lined composite pipe, the inner and outer walls of this kind of pipe are smooth, the airflow is smooth, the wear is extremely low, and the pressure resistance and corrosion resistance are good. It has been proved by practice that the wear-resistant ceramic pipes produced by Iberno have a service life of at least five years in the high nickel ternary production line.    

The quality of pump tube products on the market is mixed, with many brands and different prices. Many customers do not know how to choose. Yibeno has been engaged in the sales of concrete parts and ceramic pump tubes for 15 years. With many years of work experience, it has summed up the principles that should be followed in the selection of pump tubes. .   According to the model selection: There are three main types of concrete pumps: concrete drag pumps, truck-mounted pumps, and boom pumps. Boom pumps generally use wear-resistant pump pipes, which are made of various manganese steel pipes, double-layer pipes, and ceramic pipes; vehicle-mounted pumps generally use high-pressure pipes. At present, the domestic standard of SANY high pressure is a seamless pipe with a wall thickness of at least 5 mm and an outer diameter of 140. The drag pump can be equipped with a low-pressure pump tube or a high-pressure pump tube. It can be configured according to the specific construction pressure and the vertical height of the building. Generally, the low-pressure pump tube is configured below 80 meters, and the high-pressure pump tube is configured as much as possible above 80 meters.    According to the quality of the pump tube: in the case of the same material, the heavier the weight, the thicker the wall thickness of the tube and the longer the service life. The ceramic pump tube produced by our company is 10 times the service life of manganese steel pipe and double-layer pipe. Above, the density of ceramics is only half that of steel, the weight is much lighter, and the installation is faster   Select the pump pipe according to the concrete label. The higher the vertical, the ultra-high pressure pump pipe should be used if it exceeds 150 meters. For cement grade C50 and above, more wear-resistant pump tubes should be used. In places with severe wear, it is recommended to use super wear-resistant ceramic pump tubes.

The wear-resistant ceramic plate is used in all walks of life, it has the characteristics of high hardness, hard wear resistance, corrosion resistance and impact resistance. During our construction process, we will encounter equipment that requires special-shaped linings, and at this time, a large amount of alumina ceramic cutting is required. So do you know how to cut it?   We use high hardness diamond blades to cut wear-resistant ceramic liners. There are desktop and hand-held cutting machines, and protective measures must be taken when cutting. Then how should it be cut? Many customers may not know this very well. It is impossible to cut everything like vegetables. When the high-speed rotating blade is in contact with the wear-resistant ceramic plate in the middle position, the ceramic plate will be broken under the action of shear stress. The knife must be cut from the end, so that the stress can be reduced to a small extent and will not affect the cutting of the wear-resistant ceramic plate. At the same time, pay attention to the cooling of the cutting plate. When cutting this hard material, the temperature of the knife plate will rise. Very quickly, this can cause the strength of the blade to decrease, so take care to cool the cutting blade with water.
