Construction process 1. Grind and dust and degrease the metal surface where ceramics need to be pasted (if there is an oil stain, it should be cleaned with 99% acetone; if the bonding surface is non-metallic, the surface should be polished and roughened). 2. Stir the glue evenly, mix, and mix thoroughly according to A: B=2:1 (weight ratio), apply it on the metal surface, then paste the wear-resistant sheet, hit it with a rubber hammer, and cure it at room temperature for 2 hours. 3. After curing at room temperature for 8 hours, use a small hammer to gently tap to check, and listen to the sound to judge whether there is any phenomenon that the adhesive is not fully coated. If so, it needs to be partially re-pasted.    Precautions 1. When the humidity is high in the rainy season, in order to prevent rust, glue should be applied immediately after grinding to prevent rust. 2. The proportion of glue should be accurate to avoid construction quality problems caused by inaccurate glue mix. 3. When the temperature is lower than 10°C, heating and curing should be adopted, and an iodine-tungsten lamp can heat the surface to be bonded to about 30°C, apply glue and glue bond, and heat until cured. If heating measures are not taken, especially when the temperature is lower than 0°C, the adhesive will freeze and the surface looks cured, but there is no bonding strength. The user will experience ceramic peeling off during use. The heating temperature should not exceed 50°C, otherwise, it will cause the glue to react violently and cause foaming, affecting the bonding strength.

Today we will talk about the application of abrasion-resistant ceramic lining in the wear-resistant feeding chute of the powder concentrator. First of all, what is the powder concentrator? The powder concentrator is an important component of the closed-circuit circulating grinding system. It is widely used in the production systems of cement plants and other powder concentrators and plays the role of regulating the size of finished products. Its reliability affects the normal operation of the entire production line. Due to the high abrasiveness and humidity of slag, the cleaning and replacement of worn parts of the powder concentrator have seriously affected the normal production of the powder concentrator.    Abrasion-resistant ceramic lining can solve this problem well as a solution for wear-resisting and anti-blocking of the feeding chute of the powder concentrator. The alumina ceramic lining is made of microcrystalline wear-resistant aluminum oxide, sintered at 1700 ° C and high temperature. It has high hardness and wear-resistant properties and can be widely used in powder concentrators of grinding systems in thermal power, cement, chemical industry, metallurgy, port, mining, and other industries.   The ceramic lining brick is fixed by pasting, which facilitates installation and replacement, reduces the specification and quantity of spare parts, and saves user costs. Secondly, the alumina lining has wear resistance, a smooth surface, no scraping, and no material, which can effectively prevent material blocking and is convenient for cleaning.   High alumina ceramic lining bricks have been applied in many industries because their characteristics can be targeted at different types of materials. Its wear-resistant and anti-clogging effect is noticeable, which greatly reduces the probability of material clogging, prolongs the equipment cleaning cycle, reduces the user's downtime and maintenance time, and creates additional economic benefits for the user, and the response is quite good.

The wear-resistant ceramic lining board solves the wear problem for heavy wear industries such as cement, steel, mining, lithium battery, and metallurgy. The main material of the wear-resistant ceramic lining board is alumina, and its fracture toughness KΙC≥4.8MPa•m1/2, bending strength ≥290MPa, compared with metal materials such as steel, the impact resistance is not very strong, but through some special processes, the impact resistance of wear-resistant ceramic linings can be greatly improved, so what is the impact resistance of wear-resistant ceramics? Woolen cloth? How to improve the impact resistance of wear-resistant ceramic liners?    Surface design with spherical protrusions The unique mechanical properties of spherical protrusions can evenly disperse the impact force on the liner, reducing the possibility of the liner being broken by the impact. It is a relatively common method to improve the impact resistance of wear-resistant ceramic liners.   Increase the rubber area on the surface of the liner The wear-resistant ceramic liner is mainly used in combination with rubber. We can make full use of the characteristics of the weak impact resistance of ceramics and the strong impact resistance of rubber, and give full play to the advantages of both. Ceramics are used for wear resistance and rubber for impact resistance. During the process, some rubber is exposed on the surface of the liner (round ceramic sheets can be used). It should be noted that as the rubber area on the surface of the liner increases, the ceramic area will decrease accordingly. While the impact resistance is improved, the wear resistance will be reduced. When using it, it needs to be considered comprehensively according to the actual working conditions.   Alumina for toughening treatment The impact resistance of alumina wear-resistant ceramics is indeed weak, but this problem can be solved by spherical design, vulcanized rubber, and adding zirconia, so that wear-resistant ceramic linings can adapt to most heavy wear and strong impact conditions.
