氧化鋁陶瓷芯特點Alumina ceramic core features
耐久用，輕扭矩，硬密封，耐腐蝕 Durable, light torque, hard sealing, corrosion resistance
陶瓷球芯經(jīng)1680℃超高溫?zé)Y(jié)而成 The ceramic ball core is sintered at 1680℃
采用剛玉陶瓷，ALO含量≥95% Adopt corundum ceramics, Al Ogcontent ≥95%
陶瓷球硬度HRA≥85° Ceramic ball hardness HRA≥85°
耐酸堿性∶常溫下對各種無機酸、堿穩(wěn)定 Acid and alkali resistance: stable to various inorganic acids and alkalis at room temperature
碳化硅閥芯特點Silicon carbide core features
質(zhì)量輕、高硬度、耐磨損：碳化硅球芯經(jīng)2200℃以上超高溫?zé)Y(jié)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
耐高溫：在1500℃的高溫環(huán)境下也不會反應(yīng)◎化學(xué)穩(wěn)定性好，耐酸堿腐蝕性優(yōu)良在HF酸或5mol/L HNO3中依然保持穩(wěn)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
具有優(yōu)異的導(dǎo)熱性，熱膨脹性低：在急冷急熱的環(huán)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
低摩擦系數(shù)：具有優(yōu)良的干潤滑性，啟閉更輕松 Low friction coefficient: excellent dry lubrication, easier to open and close
