Recently, the 300,000-ton high-density polyethylene (HDPE) transformer substation and the pile foundation project between Wuhan and Wuhan Iron & Steel Company under construction by Shanghai Engineering Co., Ltd. won the highest prize in the field of ethylene quality in Wuhan, Wuhan Construction Engineering Quality Excellence Award. At the same time, the Wuhan Ethylene Engineering Excellence Process Evaluation System (Demonstration Text) edited by Shanghai Engineering Co., Ltd. won the Wuhan Ethylene Project Quality Progress Award.
In Wuhan Petrochemical's annual production of 800,000 tons of ethylene project, Shanghai Engineering Co., Ltd. assumes an annual output of 150,000 tons/280 tons of ethylene oxide/ethylene glycol (EO/EG) and an annual output of 300,000 tons of high-density polyethylene (HDPE). ) Equipment EPC general contracting.
In the modern industries, advanced ceramic component is very commonly used in many, many electron vacuum devices, like electron tubes, high voltage feedthru, high current feedthru, vacuum interrupter, vacuum capacitors/Thyristors, X-ray tubes and power switches and so on.
The key point is what a metal coating covers on the surface of ceramic body, or ceramic base to achieve the vacuum hermetical and sealing, such as nickle plating, sliver plating, gold plating, copper plating and Tin plating. The main features for vacuum ceramic component as below:
-Extremely high bond/brazing strengths
-High mechanical strength
-Minimum electric resistance and vacuum tightness
-Excellent insulation
The typical form for vacuum ceramic component is to be as an insulator, ceramic packaging and ceramic body etc.
