氧化铝陶瓷芯特点alumina ceramic core features
耐久用，轻扭矩，硬密封，耐腐蚀 durable, light torque, hard sealing, corrosion resistance
陶瓷球芯经1680℃超高温烧结而成 the ceramic ball core is sintered at 1680℃
采用刚玉陶瓷，alo含量≥95% adopt corundum ceramics, al ogcontent ≥95%
陶瓷球硬度hra≥85° ceramic ball hardness hra≥85°
耐酸碱性∶常温下对各种无机酸、碱稳定 acid and alkali resistance: stable to various inorganic acids and alkalis at room temperature
碳化硅阀芯特点silicon carbide core features
质量轻、高硬度、耐磨损：碳化硅球芯经2200℃以上超高温烧结而成，硬度≥hra90 light weight, high hardness and wear resistance: silicon carbide ball core is sintered at super high temperature above 2200 ℃, hardness ≥ hra90
耐高温：在1500℃的高温环境下也不会反应◎化学稳定性好，耐酸碱腐蚀性优良在hf酸或5mol/l hno3中依然保持稳定 high temperature resistance: it will not react under the high temperature environment of 1500 ℃ ◎ good chemical stability, good acid and alkali corrosion resistance, stable in hf acid or 5mol/l hno3
具有优异的导热性，热膨胀性低：在急冷急热的环境下不易崩裂 it has excellent thermal conductivity and low thermal expansion: it is not easy to crack in a hot and cold environment
低摩擦系数：具有优良的干润滑性，启闭更轻松 low friction coefficient: excellent dry lubrication, easier to open and close
