The powder separator is an important part of the production system of a chemical plant, and its stability is directly related to the operation of the entire production line. We found that the feeding chute of the powder separator often has problems with material blockage and wear. If the situation is serious, it needs to be cleaned for a week. Therefore, it is urgent to deal with the blockage and wear of the feeding chute.   The greater the hardness of the material in the powder separator, the more wear and tear the feeding chute. Over time, the chute is worn and damaged, and it needs to be shut down for maintenance, which not only wastes a lot of manpower and material resources but also affects the entire production operation. Wear-resistant Ceramic lining can effectively solve this problem.    The wear-resistant ceramic lining is a corundum ceramic sintered at a high temperature of 1700 degrees after dry pressing and forming with alumina as the main body, adding a calcining agent. It has the characteristics of high wear resistance, heat resistance, and corrosion resistance. The ceramic is pasted on the surface of the equipment as a protective layer of the machine to avoid wear and tear. The ceramic liner is easy to install and has a smooth surface, which is suitable for dealing with material blockage and wear problems. It greatly reduces downtime and maintenance time and improves the efficiency of the entire production.

The two most commonly used methods for installing ceramic linings in wear-resistant ceramic pipes are direct pasting and stud welding, both of which can improve the service life of the pipe and protect the inner wall steel from the direct impact of wear and corrosion of the material. , but the two are different in cost, process, and use effect. Let's take a look at the advantages and disadvantages of the two processes of paste-type ceramic lining and welding-type ceramic lining.   The advantages of the paste-type wear-resistant ceramic lining are that the construction cost is relatively low, the process is relatively simple, and it can be installed in small pipes with a diameter of about 80mm. Even equipment with a slightly more complex internal structure can also install paste-type wear-resistant ceramics; The disadvantage of the paste-type wear-resistant ceramic lining is that the connection between the ceramic and the equipment mainly depends on the ceramic adhesive. and impacted areas.    The advantage of the welded wear-resistant ceramic lining is that it is fixed by a combination of stud welding studs and inorganic adhesives, which can operate normally at a high temperature of about 600 degrees Celsius for a long time. The wear resistance and impact resistance are relatively better when used in equipment or parts that are subject to greater impact, such as parts and components; the disadvantage of welded wear-resistant ceramic linings is that the construction cost is relatively high, the process is more complicated, and the labor cost is higher. , The size of the tiles is generally more than 40mm, and welding equipment is required, which cannot be used in small pipes.   The adhesive type wear-resistant ceramic lining and the welding type wear-resistant ceramic lining have their advantages and disadvantages, which need to be selected according to the actual situation.  

After the concrete pump pipe is used, it needs to be cleaned in time. The common cleaning methods include water washing and air washing. In comparison, the water washing method is easy to operate and less dangerous. Most manufacturers use the water washing method to clean the concrete pump pipes. , Today we will talk about the method and precautions of pump tube washing.   Washing method: Put the water-soaked mud bag and cleaning ball into the cleaned conical pipe, connect the conical pipe and pipe, close the discharge door, and then fill the hopper with water (the water must be kept constant). Pump water until the wash ball emerges from the front end of the concrete pump tube.    Precautions: 1. Before cleaning, it is recommended to pump 0.5-1 cubic meter of mortar. After pumping all of it, stop the machine, flip the switch of the plate valve, and then remove the pressure of the accumulator. 2. At the end of the washing, be sure to pay attention to the water in the pipeline, do not flow to the concrete pouring site, so as not to affect the quality of the concrete. 3. Washing requires a small gap between the cutting ring and the eye plate (the butterfly valve pump requires a small gap between the plate valve and the tie rod and the upper and lower wear plates) and requires a large amount of water, which must be strictly sealed to ensure that the water after cleaning does not penetrate forward. 4. At present, wear-resistant ceramics are mostly used in the anti-wear layer of the pipeline of the pump truck. When cleaning this type of pipeline, attention should be paid to avoiding violent impact and avoiding the collision of metal and other hard objects, so as not to cause ceramic rupture. 5. Choosing a wear-resistant lining with higher smoothness can greatly reduce the difficulty of cleaning. The wear-resistant ceramic pump truck pipeline has self-lubricating components, which are easy to clean and has strong wear resistance, and its density is only half of that of steel pipes, so it is very convenient to disassemble and install.

The impact resistance of the ceramic wear-resistant lining plate is weak, and the wear-resistant ceramic sheet is directly combined with the inner wall, which has no buffering effect on the abrasive material. For materials with high impact, the ceramics are easily broken under a long-term operation environment. The composite sheet and rubber can play a very good buffering effect, which can solve the problems of fragile ceramics and noise.    It is suitable for the installation of various special-shaped equipment after vulcanizing ceramics and rubber into an integral lining board.   The ceramic surface will not bond with the material, and the long-term operating environment of the equipment will not cause material blockage and waste of material.   The wear-resistant ceramic rubber composite board has a lower density than steel plate, is lightweight, has easy installation, good wear resistance, and greatly saves maintenance costs.  

The wear-resistant ceramic composite steel plate is a kind of wear-resistant lining material with high wear resistance, high corrosion resistance, and high impact resistance, which is made of alumina (AL2O3) as the main material and is calcined at a high temperature of more than 1,000 degrees Celsius. Generally, the wear-resistant ceramic lining plate is composed of a bottom steel structure, the middle layer is a wear-resistant ceramic paste, and the surface layer is a wear-resistant ceramic material. Mainly used in steel mills, mine hoppers, trough machinery, coal, mining, chemical industry, cement, port logistics, and other companies in the conveying system, pulverizing system, ash discharge system, and other industrial equipment with greater damage, such as dust removal equipment, conveying equipment, etc.    Wear resistant ceramic composite steel plate product advantages: 1. It is not easy to be damaged. Alumina ceramics use 95% AL2O3 to add a variety of wear-resistant materials, and are formed by 100 tons of dry pressing, with high density, high toughness, and high wear resistance; 2. Cold and heat resistant, the development is developed on the basis of years of experience. A variety of ingredients are added to the rubber, so that the rubber will not change its internal structure at high temperatures of minus 50 degrees and 100 degrees, thereby reducing the phenomenon of rubber aging and ceramic peeling; 3. Impact-resistant and wear-resistant ceramics have been introduced into foreign technology to achieve the effect of refining grains, promoting calcination, and improving fracture toughness; 4. The adhesion is firm, the wear-resistant ceramic material is firmly bonded to the steel, and the wear-resistant ceramic lining board uses a two-component wear-resistant ceramic paste, which has a firmer adhesion and the ceramic is not easy to fall off. The wear-resistant ceramic liner has strong adhesion, good heat resistance, corrosion resistance, wear resistance, aging resistance, and other characteristics. According to data analysis, in the past ten years, wear-resistant ceramic linings have been used by many customers, and the stability is very good. So far, there has been no problem with the product falling off. It is very suitable for anti-wear application of material conveying systems with high impact force and serious wear.   http://www.ybnceramic.com/alumina-ceramic-liner/ceramic-rubber-composite-liner.html

Alumina ceramics have been widely used in many industries because of their excellent properties. Alumina ceramics is a general term for ceramic products made of calcined alumina as the main raw material. Due to the different content of alumina, it is divided into 75 ceramics, 85 ceramics, 90 ceramics, 95 ceramics, and 99 ceramics.   The raw material processing methods of alumina ceramics mainly include a dry method and a wet method. The dry method mainly uses a roller ball mill for dry grinding, and the wet method mainly uses a roller ball mill, stirring mill, and sand mill for wet grinding.   There are many molding methods for alumina ceramics, but the most important ones are grouting, hot die casting, film rolling, dry pressing, isostatic pressing, casting, injection and gel injection molding, etc. Different molding methods correspond to different processes.      The raw material processing methods of hot die casting and rolling film are mainly dry grinding, and the raw material processing methods of grouting, dry pressing, and isostatic pressing are mainly wet grinding. Hot die-casting, rolling film and gel injection molding, and other molding methods also need to mix organic matter into the processed powder, and dry-pressed and isostatic-pressed powders need to be granulated after wet grinding. The current granulation The equipment mainly includes a pressure spray drying tower and a centrifugal spray drying tower.   Different molding methods use different molds. The grouting method uses plaster molds, the hot die casting method and dry pressing method uses metal molds, and isostatic pressing mainly uses rubber molds.   The above-mentioned various molding methods have different molding principles and processes, so their characteristics are also different, and each has its own advantages and disadvantages. The choice of ceramic molding method should be comprehensively determined according to the performance requirements, shape, size, output, and economic benefits of the product. Grouting molding uses cheap plaster molds, simple equipment, and low cost, and is suitable for the manufacture of complex-shaped ceramic parts and large-sized ceramic products.   Dry pressing can form ceramic products with complex shapes, with high dimensional accuracy and almost no need for follow-up processing. It is the main molding process for making special-shaped ceramic products; it is especially suitable for the preparation of various ceramic products with small cross-sectional thicknesses, such as ceramic sealing rings, Ceramic water valves, ceramic liners, ceramic lining, etc.   The formed body is dried or degreased and loaded into a kiln for sintering. The corresponding sintering system is formulated according to the different alumina content. Theoretically, the higher the alumina content, the higher the sintering temperature required. Sintering equipment mainly includes a pusher kiln, tunnel kiln, roller kiln, shuttle kiln, and bell kiln.   After the fired alumina ceramic products are cleaned and selected, those with low requirements on dimensional tolerance and surface roughness can be directly packaged, and those with high requirements on the above two indicators must be ground and polished.   http://www.ybnceramic.com/wear-resistant-ceramic-pipe/ceramic-sheet-ceramic-tube/wear-resistant-ceramic-patch-pipes.html

Alumina wear-resistant ceramic sheets are widely used in all walks of life because of their high hardness, super wear resistance, corrosion resistance, and impact resistance. During the construction process, ceramic cutting is essential, which is usually used What cutting, and what precautions let us understand together: 1. We use high-hardness diamond blades to cut wear-resistant ceramic sheets. There are mainly two types of cutting machines: desktop and handheld. When cutting, take good protection to avoid cutting the skin. 2. Many customers will break everything in the process of cutting ceramics. The correct cutting method: the position of the blade must be cut from the end so that the stress effect can be reduced to a minimum and it will not damage the wear resistance. The cutting of the porcelain plate is affected, especially when the high-speed rotating blade contacts the wear-resistant ceramics in the middle position, the ceramic block will be broken due to the shear stress, and attention should also be paid to the cooling of the cutting plate.    3. Laser cutting is also a method, that is characterized by narrow cutting width and can also perform curved cutting, but the only disadvantage is that it cannot cut too thick ceramic sheets. 4. In industry, wear-resistant ceramic sheet cutting tools are generally cut with diamond blades, which can achieve high precision and play a great role in precision cutting, grooving, or sawing. If the side has a taper The advanced cutting wheel can also avoid the adverse effects caused by the dulling of the abrasive, 5. When cutting wear-resistant ceramic sheets, the waterproof cover needs to be installed in sequence. During the cutting process, friction generates a lot of heat, so it is easy to generate heat, deformation, expansion, and looseness. The temperature rises quickly, which will lead to a decrease in the strength of the blade, so it is very important to pay attention to cooling the blade with water.

The main component of an alumina ceramic sheet is alumina. The wear-resistant ceramic sheet is made of alumina powder pressed by a press and then fired in a high-temperature furnace at 1700°C. It is characterized by the advantages of hard °C, high wear resistance, etc., has been widely used in industrial and mining enterprises, and has been recognized by customers in recent years. It has become the leading product in the anti-wear industry, but the wear-resistant ceramic sheet itself does not have the paste function and needs to be used in conjunction with ceramic glue. How to choose The ceramic glue is also a very particular issue, because ceramic glue is used as the adhesive when the ceramic piece is installed. Only by choosing the correct ceramic glue can the strength of the ceramic piece achieve the best effect. There are three types of ceramic adhesive commonly used:    1. Normal temperature type: the use temperature is within 100°C and has a good paste effect. It is also a commonly used model and variety, but its temperature resistance area can only be within 140°C, and the paste performance will decrease if it exceeds 100°C. As the temperature rises, it will gradually lose its adhesive ability. 2. High-temperature type: the use temperature is within150°C- 250°C, its adhesive performance is the same as that of normal temperature glue, but its temperature resistance is as high as 250°C, and it has a very good effect on bonding the top and side, due to its high-temperature resistance Relatively speaking, it is relatively viscous, and it has a good effect on connecting large ceramic plates. There will be no problems such as falling off or flowing the ceramic plate before it is cured after being pasted. 3. High-temperature resistant type: high temperature-resistant ceramic glue is developed and produced for parts where 250°C-350°C are used, and it has a good effect on high-temperature parts, but the overall price will rise due to high cost.   The ceramic glue developed by our company can be used in an environment of 350°C for a long time, with very stable performance and good acid and alkali corrosion resistance. Its superior performance has been highly recognized by the majority of users. After the customer's application and feedback, it has been well received. The ceramic glue produced by the company has significant advantages such as no flow, good adhesion, and convenient construction.  

The Spring Festival is the most solemn and lively traditional festival among the Chinese people. It is the first day of the first lunar month every year, also known as the lunar year; it is also a traditional annual festival. The Spring Festival, also known as the Lunar New Year, is the beginning of the year and the most solemn traditional festival of the Chinese nation. New Year's Eve, the last night at the end of the year. The last day at the end of the year is called "Sui Chu", which means to remove the old year and replace it with a new one. So do you know the origin and customs of the Spring Festival? Next, let's go and see together! Regarding the origin of the Spring Festival, due to the lack of ancient documents, it is impossible to directly verify its origin, but in the historical development and evolution, many stories and legends have been left as its origin. Pray for good wishes: The word "Nian" in Chinese New Year means a good year and a good harvest. For thousands of years, people have always called a good harvest in the lunar calendar "a good year", and the first day of the first lunar month the "day of the year". First of all, starting one year, it has become one of the grandest traditional festivals of the Chinese nation and even the Chinese in the world. On September 27, 1949, New China was established. At the first plenary session of the Political Consultative Conference of the Chinese People's Government, the first day of the first lunar month in the Gregorian calendar was designated as New Year's Day, commonly known as the Gregorian calendar year; Therefore, the first month of the lunar calendar must be "Spring Festival", commonly known as the Gregorian calendar year.      Traditions custom 1. Worshiping ancestors Due to the different customs in various places, the forms of ancestor worship are also different. Some go to the wild to visit the ancestral tomb, some go to the ancestral hall to worship the ancestors, and most of them place the ancestral tablets in the main hall in turn at home, display the offerings, and then the worshipers press the long The younger ones offer incense and kneel down to worship. 2. Post-Spring Festival couplets While pasting Spring Festival couplets, some families have to paste the character "Fu" on the house door, on the walls, and on the lintel. The word "Fu" refers to blessing and good luck, and it expresses people's yearning for a happy life and wishes for a better future. In order to more fully reflect this yearning and wishes. 3. Set off firecrackers There is a saying in Chinese folk that "open the door and firecrackers". Promptly when the new year arrives, the first thing that every household opens the door to is exactly to set off firecrackers, to get rid of the old and usher in the new with the sound of firecrackers that beep, beep, beep. Firecrackers are a Chinese specialty, also known as "firecrackers" and "firecrackers". Its origin is very early, and it has a history of more than two thousand years. 4. Eat New Year's Eve dinner Eating New Year's Eve dinner is the most lively and happy time for every family during the Spring Festival. The New Year's dishes are all prepared a few days ago, and the New Year's Eve dinner must always be prepared by the chef on New Year's Eve. The New Year's Eve dinner is the "longest" meal that Chinese people eat throughout the year, and it is also the most important family banquet for Chinese people. We have finished the Spring Festival holiday and have devoted ourselves to the intense work of 2023. We sincerely welcome overseas friends to come to China to experience the most solemn traditional festival in China - the Spring Festival!
