Vacuum aluminizing film is a production process which we make aluminum metal evaporating and then plate it on the surface of the film base material to form a composite film under the vacuum condition. BOPET, BONY, BOPP, PE, PVC and other plastic film adopt direct aluminizing process, the aluminizing for paper and leather will choose evaporation - transfer process. The graphite crucible is the essential consumable parts in vacuum aluminizing film production, the quality of graphite crucible will affect the product quality and the production cost of aluminizing film directly. The vacuum aluminizing has stringent requirements to the graphite crucible. The appropriative vacuum aluminizing graphite crucible produced by our company has the following advantages: Our graphite crucible produced by the…
With the development of railway transportation, the request of the train itself is further improved, especially in the load and speed. With the increased speed, increased load, wear the train wheel flange also intensifies, at the same time, also aggravate the rail wear. The rims of the maintenance, replacement has caused huge waste, and the consumption of maintenance and replacement of rails is more beyond imagination. So, the train locomotive wheel flange lubrication on the imminent problem. The train locomotive flange lubrication refers to the lubrication measures in locomotive wheel and rail contact, the contact surface friction, reduce wear and tear on the train and railway tracks and loss of flange. The train locomotive wheel includes lubricating grease lubrication and…
Among all kinds of electrode materials of vanadium redox flow battery, graphite felt is the best comprehensive performance of electrode material, but it still needs to be activated to enhance its performance. As one of the most important parts of vanadium battery, electrode and its related characteristics, including cost and processing technology, have become the key aspects of the research and development of vanadium battery system. Choosing appropriate electrode materials can improve the electrochemical activity of the electrode, and ultimately improve the energy efficiency of vanadium battery. Vanadium battery electrode materials are carbon, such as graphite, carbon cloth, carbon felt, etc., there are metals, such as Pb, Ti, etc., there are conductive polymer or polymer mixture composite electrode. But from…
