In the production and operation of enterprises, the choice of pipes has a vital impact on cost control and efficiency improvement. Our company's wear-resistant ceramic pipes are undoubtedly the best choice for many companies to save money.   Alumina ceramic pipes have the advantage of a longer service life. Its service life is more than 6 times that of ordinary wear-resistant pipes. It can save the time of annual downtime for pipe replacement. For enterprises, downtime often means stagnation of production, which is a huge loss. Our wear-resistant ceramic pipes can reduce this loss to a very low level, thereby improving productivity. The increase in productivity has undoubtedly brought more output and benefits to the enterprise. At the same time, less downtime and longer life also greatly reduce the total production cost. For example, for ordinary wear-resistant steel pipes, the life span is only 1 year, while our ceramic pipes can be used for 5 years. On the surface, the initial cost seems to be higher than ordinary wear-resistant steel pipes. However, as time goes by, the results are very different. In a 5-year cycle, compared with ordinary wear-resistant steel pipes, pipe lining ceramic saves multiple downtime and installation costs. Ordinary wear-resistant steel pipes need to be installed every year, while ceramic pipes only need to be installed once.   In addition, wear-resistant ceramic pipes have additional cost-saving advantages. Compared with ordinary wear-resistant steel pipes, it requires less maintenance and repair. In the production process of an enterprise, the maintenance and repair of equipment and pipelines often require a lot of manpower, material resources, and time. This feature of wear-resistant ceramic pipes means that the enterprise will have less maintenance time, which can allow employees to devote more energy to production. At the same time, lower maintenance costs also further reduce the company's expenditure on pipelines, saving money for the company and enhancing the company's competitiveness in the market. Choosing alumina ceramic lining for pipelines is to choose an efficient, economical, and reliable pipeline solution.

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.

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, 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 surface of the wear-resistant ceramic lagging developed by our company has corundum ceramic as the anti-wear layer to increase its surface friction. Polyurethane, which is famous for its wear-resistant rubber, is used as the vulcanized layer and then bonded with imported high-strength adhesives. The normal service life is more than 10 times that of the rubber-coated drum.

When it comes to ceramics, everyone will feel very familiar. It has penetrated into all aspects of our lives. There are many ceramic products in our daily pots and pans, and our Chinese ceramics are world-renowned and are the works of art that many people dream of. And collectibles, the Chinese English word "china" also means ceramics. However, today's ceramics are not only used in life, but also occupy an increasingly important position in many fields such as industry, scientific research, food, medical care, etc. They have a new name called special ceramics. So what is special ceramics? How is it different from ordinary ceramics?   The term special ceramics first appeared in the UK in the 1950s. At that time, people were called refractory materials, electronic ceramics, electric ceramics, atomic energy ceramics and so on due to their different properties and uses. It refers to the use of high-precision selected raw materials, with a chemical composition that can be precisely controlled, manufactured and processed according to methods that facilitate structural design and controlled manufacturing, and have excellent properties. Nowadays, it has many different names in different countries and regions. In the UK, it is called technical ceramics. In the United States, it is called advanced ceramics, modern ceramics or high-efficiency ceramics. In Japan, it is called fine ceramics and new ceramics. In our China, the name of special ceramics is widely known, but in addition, people also call it industrial ceramics and advanced ceramics.    There are obvious differences between special ceramics and ordinary ceramics, mainly in the following aspects. 1. Different raw materials: traditional ceramics use natural minerals as raw materials, such as clay, quartz, feldspar, etc.; while special ceramics use less or no clay, but use various processed chemicals or synthetic minerals as raw materials, such as alumina , zirconia, etc.   2. Different structure: traditional ceramics have many impurities and pores due to the relationship between materials and processes; while special ceramics are fine in texture and have excellent characteristics in terms of hardness, strength, high temperature, corrosion, oxidation, wear, etc. .   3. Different properties: Most traditional ceramics are mainly used for viewing and daily use; while special ceramics are often used in different aspects due to their own characteristics, such as high temperature resistance, oxidation resistance, corrosion resistance and other characteristics. .   4. Different production processes: The traditional ceramic production process is simple. After grouting, it can be shaped, and it can be simply fired if it is more complicated; and a series of complex production methods for special ceramics, whether it is pre-pressing, It takes a long time for injection, lamination or later isostatic pressing. If nothing else, it is much more complicated and stricter than traditional ceramics in terms of molding, not to mention the final cutting, Punch, grind and polish.   5. Different applications: traditional ceramics are mostly used in daily life, such as cups, bottles, pots, etc., which are commonly used in our daily life. Some of the more exquisite ones are used as handicrafts, and most of them have ornamental value; while special ceramics are different. Different characteristics, applied in various aspects, completely break the use restrictions of traditional ceramics, can be widely used, and bring convenience to people's lives.  

Wear-resistant ceramics are special corundum ceramics made of AL2O3 as the main raw material, rare metal oxides as the flux, and calcined at a high temperature of 1700 Baidu. As a new type of workpiece material, industrial ceramics have high-temperature resistance, high wear resistance, good toughness, high-temperature insulation, impact resistance, corrosion resistance, beating resistance, good welding performance, etc.   Features of wear-resistant ceramic lining: It has the characteristics of wear resistance, impact resistance, corrosion resistance, high-temperature resistance, and convenient construction. , ore concentrate, tailings, cement, etc.) is an ideal material for surface wear of conveying equipment. It is very safe to use in high-temperature corrosion, high-temperature wear, or high-temperature corrosion lining occasions, and its service life is longer than that of cast stone, wear-resistant alloy cast steel, steel Plastic, steel rubber, and other materials are ten to twenty times higher.    There are many forming methods of alumina ceramics, but the main ones are grouting, hot die casting, film rolling, dry pressing, isostatic pressing, casting, injection and gel injection molding, etc. Different forming methods correspond to different processes.   Different molding methods use different molds. Gypsum molds are used for grouting, metal molds are used for hot die casting and dry pressing, and rubber molds are mainly used for isostatic pressing. The above-mentioned various molding methods have different molding principles and processes, so their characteristics are also different, and each has its 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. The grouting adopts an inexpensive gypsum mold, with simple equipment and low cost, and is suitable for the manufacture of complex-shaped ceramic parts and large-sized ceramic products.

The main component of an alumina ceramic sheet is alumina. Because of its high hardness and outstanding wear resistance, it has become the main product in the anti-wear industry, but the wear-resistant ceramic sheet itself does not have the function of sticking and needs to be used with ceramic glue. How to choose the ceramic glue is also a very particular problem, because the ceramic glue is used as the adhesive when the ceramic sheet is installed. Only by choosing the correct ceramic glue can the strength of the ceramic sheet achieve the best effect. The commonly used ceramic adhesives are roughly divided into three kinds:   1. Normal temperature type; the use temperature is within 150 degrees, which has a good sticking effect, and is also a commonly used model and variety, but its temperature-resistant area can only be within 150 degrees, and the sticking performance will decrease when it exceeds 150 degrees. The rise will gradually lose the sticking ability.    2. Medium temperature type; when the operating temperature is within 250 degrees, its bonding performance is the same as that of normal temperature glue, but its temperature resistance is as high as 250 degrees, and the top and side surfaces of the bonding equipment have a very good effect. Due to its high-temperature resistance, it is relatively It is relatively viscous, and it has a good effect on bonding large ceramic plates. There will be no problems such as falling off or flowing the ceramic plate before it is cured after pasting.   3. High-temperature type; Temperature-resistant ceramic glue is developed and produced for the use part of 350 degrees, and has a good effect on the high-temperature part, but the overall price will rise due to the high cost.  

The pulverized coal pipeline is used to transport high-temperature gas mixed with hard particles. Its operating characteristics are high temperature, high flow rate, high particle hardness, and serious equipment wear, especially the elbow part, without any protective measures. Put on. Most of this equipment is mounted on high-altitude supports, which are inconvenient for maintenance. Once worn out, the safe use of the equipment will be seriously affected.   The service life of the pulverized coal conveying pipeline is greatly improved after being lined with wear-resistant ceramics. The corundum ceramic lining is a material with wear resistance, high-temperature resistance, high hardness, acid and alkali corrosion resistance, and very high thermal stability. The steel pipe is bonded by wear-resistant ceramic adhesive, which is convenient for construction, has high bonding strength, and the lining is smooth and does not accumulate material.    Ceramic pipes are lined with corundum ceramics, which is generally ten times or even dozens of times that of ordinary steel pipes, and has a qualitative leap in wear resistance with wear-resistant alloy cast steel pipes and cast stone pipes. The service life of ordinary steel pipes is half a year to one year, and the service life of wear-resistant ceramic pipes can reach 5 to 10 years, which greatly reduces the number of equipment downtime and maintenance, and saves a lot of manpower and material costs for enterprises. It is a very cost-effective anti-wear scheme for pulverized coal conveying pipelines.

Wear-resistant ceramic glue is the main tool for fixing wear-resistant ceramic tube lining ceramics. Its use method is very different from ordinary glue. Let's talk about the specific use steps of wear-resistant ceramic glue. Grinding and dust removal: Before pasting the wear-resistant ceramic sheet, first grind and dust off the steel parts of the porcelain pasting equipment to remove rust until the original color of the metal is exposed.   Glue.:Under normal temperature conditions, mix according to the ratio of AB glue 2:1, and stir evenly, after the preparation is completed, try to use it up within 30 minutes to prevent the glue from curing.    Apply: Apply glue to the ceramic parts that have been polished and cleaned, and be sure to apply it fully, and there should be no glue shortage. Make sure that the front and all sides of the ceramics are covered with adhesive, and the gaps between the ceramics should also be filled with adhesive.   Bonding: After the gluing is completed, use a blade to cut the adhesive tape, and use a wooden hammer to compact the ceramic sheet to let the excess glue flow out. To ensure the adhesive strength, the thickness of the glue should be kept within 0.5mm.   Patching: The gap between the ceramic sheets should be filled with wear-resistant ceramic glue, the size of the gap should be kept within 1mm, the glue should be evenly filled, and there should be no glue leakage. Curing: After the ceramic sheet is pasted, it can be put into use after curing for 24 hours to 48 hours.

The installation process of alumina ceramic tube is mainly divided into three steps: porcelain ring splicing, porcelain ring pasting and grinding. Porcelain ring splicing: Porcelain rings are spliced with glue according to the requirements of the drawings to ensure that the interior is flat. Porcelain ring paste: apply the adjusted adhesive on the inner wall of the pipe to ensure that it is even, and then apply the adhesive on the spliced ceramic ring to ensure that the entire pipe is pasted on the inner wall of the pipe at one time. After fixing, check whether there is any dislocation and leakage of glue on the inner wall of the pipe. After checking, place the pasted pipe in the designated position. Grinding: After the adhesive is completely cured, grind the excess ceramic rings on both sides of the pipe to ensure that it is flat and does not damage the flange.
