产品应用之——纳米耐磨陶瓷
Product introduction Application-nanometer abrasive ceramics
耐高温性:由于纳米陶瓷内筒是以SiC和A12O3为主体原料,经过2300℃高温重新结晶制成,所以它的高温性能经测试可以达到1500℃左右。
High temperature resistance The inner cylinder of nanometer ceramics uses SiC and A12O3 as main raw materials with the temperature hitting 2,300 degrees Celsius, so the inner cylinder can work long time in the temperature of 1,500 degrees Celsius
耐磨性:由于采用重结晶技术SiC和Al2O3纳米陶瓷具有很高强度,莫氏硬度达到≥9。
Abrasion resistance The rigidity of nanometer ceramics is high with special technology, and mohs hardness is greater than or equal to 9.
高险蚀性:由于SiC和Al2O3纳米陶瓷经高温烧制而成,高温化学性能稳定,是一种无机功能材料,具有很强的耐酸碱及各种复杂气体腐蚀能力。
Corrosion resistance As an inorganic functional material, nanometer ceramics have very good chemical properties in high temperature conditions, and excellent acid-alkali corrosion resistance.
抗结皮:SiC和Al2O3纳米陶瓷高温化学性能稳定,与氧化钙等酸碱物质不产生任何化学反应,避免了水泥原料(氧化钙)结垢在上面的现象。
Skinning resistance Nano-ceramics has very good chemical properties in high temperature conditions,and has good acid-alkali corrosion resistance. Therefore, it’s difficult for cement to scale on the surface of nano-ceramics.
重量轻:SiC和Al2O3比重轻为300kg/立方米,而耐热钢为8000Kg/立方米,一套陶瓷内简的重量只是耐热钢重量的1/3左右,经专凉计算,一般预热塔一至五级筒,使用耐热钢内筒总重量为80t左右,而用陶瓷内简只有20t左右,使预热塔重量减轻了60t吨左右,预计可延长整体预热塔寿命10年左右。
Light weight The weight of a refractory steel cylinder is three times as the weight of an inner cylinder of nano-ceramics. In generally, the inclusion of inner cylinder of nano-ceramics in preheater tower will eliminate 60t weight and increase of service life for 10 years.
热震稳定性能好:由于SiC和Al2O3纳米陶瓷导热性能好,热膨胀系数小,具有抗热性能好,耐冷热急变可达50次以上,结构合理,优化模块化挂节:施工方便,可降低劳动强度,减少施工时间及维修费用。
Excellent thermal shock stability Nano-ceramics has small thermal expansion coefficient, good thermal stability. As a result, the nano-ceramics can pass through 50 times of high and low temperature testing.
