How To Improve The Oxidation Resistance Of Graphite Products

XRD graphite has good characteristics such as electrical conductivity, thermal conductivity, high temperature resistance, corrosion resistance etc. So that it can be widely used in kinds of industries. However, how to prolong the service life of the graphite products? It is absolute principle to improve the oxidation resistance in the high temperature environment.

After high temperature anti-oxidation coating processing, graphite electrode, graphite crucible, graphite rods can be seep into the pores by the liquid, a layer of protective film is formed on the surface of the graphite crucible, which can prevent air directly from contacting with the graphite electrode, graphite crucible, graphite rod to avoid oxidation reaction, after dipping coating of the antioxidant treatment, which can’t crack and spall in high temperature changes as to extend the lifetime by effectively delaying the oxidation.

The Performance And Application Of Graphite Rod

Graphite Rod is not metal products,as an importmant cutting consumables of carbon arc air gouging cutting process,it is made of carbon,graphite and the appropriate adhesive,after a series of processes,it is finished.grahpite rod is high temperature resistance,good electrical conductivity,and not easy to break,also it is easily shaped by metal cutting.

Due to the features of high temperature resistance,good conductivity and chemical stability,it is widely used in defense,machinery,metallurgy, chemical,casting,non-ferrous metal,light,etc.it becomes the non-matal materials of the most widely used.when cut irons,it’s very safe and low cost.it will get better results,when it is machining cast iron,stainless steel,copper,aluminum etc.

Graphite rod is is hard and brittle,small expansion coefficient,thermal shock,not easy to deformation,it has good chemical stability.flexural strength of the graphite rod will increase as the temperature rises.
