Features
1. Ultra-hard core wear-resistant performance: redefine the industrial protection standard
Temperature-resistant ceramic liner adopts 99.5% high-purity alumina ceramics as the core wear-resistant layer, and its Vickers hardness is as high as 1800-2000HV, which is equivalent to 10 times that of ordinary carbon steel (150-200HV) and 8 times that of stainless steel (200-250HV), and the hardness is only second to diamond. In quartz sand, slag and other strong wear scenes, ordinary steel chute annual wear up to 2-5 mm, need to be replaced frequently; and ceramic liner annual wear rate is only 0.01-0.03 mm, service life extended by 50-100 times, especially for mining crushing line, coal transmission system of thermal power plants and other "high wear hell" environment, and Significantly reduce equipment downtime maintenance costs.
2.Flexible shock absorbing design: a strong and flexible impact protection program
The liner adopts **"ceramic + rubber matrix" composite structure **, in which the rubber layer is not only the flexible support of ceramic, but also has excellent impact absorption ability: when the material impacts the chute at a high speed of 5-10m/s, the rubber layer can absorb 75-80% of the impact energy, and the impact absorption rate is as high as 85-90%. This feature significantly reduces the rigid impact on the equipment substrate damage, so that the chute life extension of 3-5 years, while reducing the working noise from 90 dB or more to less than 70 dB, improving the comfort of the industrial environment, in line with the requirements of the modern factory low-noise.
3.The extreme environment corrosion resistance: acid and alkali media in the "protective barriers"
The liner material combines the chemical inertness of ceramics with the corrosion resistance of special rubber:
High purity alumina ceramics (purity ≥ 99.5%) in pH = 2 (strong acid) to pH = 13 (strong alkali) in extreme environments, the annual corrosion rate <0.01mm, only ordinary carbon steel (0.5-1.0mm / year) 1/50-1/100;
Special rubber matrix can withstand salt spray, oil, solvents and other media erosion, suitable for chemical raw materials transportation, metallurgical waste treatment and other highly corrosive scenarios. Whether it is the pipe lining of the sulfuric acid production line, or the protection of the discharge chute in the soda ash industry, can maintain more than ten years of stable performance, to avoid the risk of leakage due to corrosion and perforation of traditional metal materials.
4.Low surface energy anti-adhesion: so that the material "smooth as running water"
Through nano-scale surface modification technology, the surface energy of the liner is as low as 30-35mN/m, which is only 1/15-1/20 of ordinary steel (500-600mN/m), close to the hydrophobic properties of Teflon material. When conveying wet sludge, viscous powder and other easy to scale materials, the material residue rate of ordinary metal chute is as high as 40-50%, requiring daily downtime to clean up; while the ceramic liner surface is almost free of material adherence, the residue rate is less than 5%, which can realize continuous, maintenance-free operation, especially suitable for the cement raw material conveying, biomass fuel unloading scenarios, to enhance the production capacity of efficiency and reduce the cost of manual cleaning up to more than 70%. V. Adaptability to industrial scenarios.
5.Industrial scene adaptability: the "universal solution" for the whole chain protection.
From the drop hopper of mining crushing and screening line, the belt transfer point of coal transmission system in thermal power plant, to the corrosive medium pipeline in chemical plant, high temperature slag chute in iron and steel mills, temperature resistant ceramic liner achieves accurate protection for all kinds of equipments through diversified structural design (e.g. planar liner, curved liner, embedded combination of liner) and customized installation solutions. Its wide temperature adaptability from **-50℃ to 300℃** makes it the preferred choice for extreme temperature scenarios such as North and South Pole research equipment and metallurgical blast furnace discharging system.
