Raku-Raku®超高温石墨增强复合垫片
是从最新研发的超高温石墨板材打孔或切割而成的，它具有良好的防腐蚀性，压缩回弹性，高强度性，而且在氧化状态下最高温度可达到650℃，在持续高温下的稳定性是普通石墨垫片无法达到的。因此解决了在超高温领域的密封要求。主要应用于航空航天、核工业、石化炼油、钢铁冶炼等众多超高温部位的密封。
Raku-Raku®Metal-reinforced Graphite Composite Gasket
The gaskets are perforated or cut from newly developed ultra-high temperature graphite sheets.It has good corrosion resistance, compression resilience and high strength,and the maximum temperature can reach 650°C in the oxidation state,the stability at constant high temperatures cannot be achieved by ordinary graphite gaskets.The sealing requirement in the field of super high temperature is solved.Mainly used in aerospace, nuclear industry, petrochemical refining, iron and steel smelting and many other ultra-high temperature sealing.
