Wear resistant ceramic particle adhesive is a non-metallic adhesive wear-resistant material, which is made of acid and alkali resistant synthetic raw materials, and is made into powdered ceramic materials through strict process ratios and advanced inorganic polymerization technology. At the construction site, special liquid inorganic glue is added to this material and applied manually or mechanically to the lining or surface of the equipment. After a series of chemical reactions, it reaches the bonding strength and hardness of ceramics at room temperature for 3 days, hence the name wear-resistant ceramic particle adhesive. Its characteristics are as follows:
1. High mechanical strength and rigidity
Wear resistant adhesive is mainly composed of wear-resistant aggregates and bonding systems, with high density, no macroscopic defects, and a strength of up to 130 megapascals, which cannot be achieved by ordinary concrete and refractory castables. Mainly using ionic compounds and some synthetic covalent compounds, their ionic bonds are firmly bonded, so their strength and stiffness are high. Ceramic particle adhesives can effectively resist the impact force and shear stress of materials. However, due to the use of composite reinforcement measures and special treatments, the bonding system forms a chemical bond, resulting in higher strength.
2. Excellent toughness and seismic performance
Due to the use of non directional rigid fibers and directional mesh reinforcement measures in wear-resistant ceramic particle adhesive, and the further improvement of toughness through coupling, it has strong fracture toughness and can effectively prevent damage and peeling caused by impact force. On the other hand, due to the strong binding of ionic bonds and their covalent bonds, the bond energy is relatively high, and low temperature has little effect on them. The vibration frequency is high, and it is difficult to pose a threat to them at room temperature, and thermal shock damage will not occur.
3. Integrity and good faith
Due to the dual reinforcement measures used in wear-resistant ceramic particle adhesives, some even adopt multiple reinforcement measures, effectively improving material properties. Moreover, due to the low coefficient of expansion and stable volume of ceramic materials, it is impossible to produce cracks, resulting in good overall integrity. In addition, the overall structure is seamless and the integrity is further improved.
4. Good environmental compatibility
Due to the use of acid and alkali resistant synthetic materials, it will not react with slag. Meanwhile, due to the fact that these materials are mostly synthesized at high temperatures, with well-developed crystals and complete structures, the environmental temperature will not have a significant impact on them. They are environmentally inert materials, so their sensitivity to the environment is poor.
5. No environmental pollution
Wear resistant ceramic particle adhesive is an inorganic non-metallic material, mainly composed of silicates, similar to the Earth's lithosphere. It will not cause soil degradation and heavy metal ion pollution, and will not affect the ecological environment. It is a green and environmentally friendly product.
By adopting the above characteristics, the wear resistance of room temperature wear-resistant ceramic particle adhesive is 9 times that of 16Mn steel, 8 times that of 65Mn steel, and 45 times that of refractory castables. It can be used as a key wear-resistant and anti-corrosion coating for various high and low temperature equipment such as cement, national defense, petroleum, and chemical industry. It is a new generation ideal material that replaces existing wear-resistant ceramics and wear-resistant steel, solving the problem of frequent component downtime and maintenance caused by wind selection wear, impact wear, and other factors in various industries.
