Ultra-high-power graphite electrode colloidal graphite is mainly used in lubrication, electrical conductivity, sealing, etc. Different types models of colloidal graphite are needed in different industrial production fields. There are many types of colloidal graphite, colloidal graphite has No. 00 colloid. Graphite, No. 0 colloidal graphite, No. 1 colloidal graphite, etc., the main role of colloidal graphite lubrication is used in metallurgical demoulding, lubricating oil, grease production, paint production other industrial fields.
Colloidal graphite lubrication can be used as a release lubricant in the production of catalysts in the fertilizer industry. Colloidal graphite is used as a release agent in powder metallurgy. Colloidal graphite added to the production of lubricating oil grease can improve the lubricating performance high temperature resistance of lubricating oil grease. Colloidal graphite can also be used as an additive in rubber plastic products. The use of colloidal graphite can also improve the performance of rubber plastic products. Wear resistance, compression resistance conductivity. In the industrial production of storage batteries, colloidal graphite can be used to produce carbon film resistors for storage batteries configure conductive coatings. The use of colloidal graphite lubrication plays a role in lubrication wear resistance in the field of industrial lubrication production.
Colloidal graphite is used in various industrial fields has played its due role in various industrial production fields. The use of colloidal graphite lubrication has an important contribution to the production of industrial lubricating materials. The use of colloidal graphite lubrication can make industrial products lubrication, wear resistance, extend products. In terms of service life, colloidal graphite has been well applied in the fields of metallurgy, lubrication, electrical conductivity. Colloidal graphite has promoted the development of industry has an irreplaceable important role. Because graphite crucible has a large volume density,
Ultra high power graphite electrode
High temperature resistance, fast heat transfer, acid alkali corrosion resistance, high temperature strength, high oxidation resistance, etc., so it will inevitably be used to prevent corrosive substances during use. Although the graphite crucible has the ability to resist acid alkali, but for the refining of individual raw materials, the cleaning work after the crucible is used is very troublesome.
For those cleaned up substances, boil them in dilute hydrochloric acid dilute nitric acid. Note that the hydrochloric acid used must contain nitric acid, nitrates, halogens other oxidants. If the dilute nitric acid cannot be cleaned, use potassium pyrosulfate, sodium carbonate borax to melt clean.
The first task of cleaning the graphite crucible is to clean out the chemical substances in the crucible, then clean it. We need to decide what to use for cleaning according to what is the residual substance in the graphite crucible. Generally, the attachments on the graphite crucible are inorganic We can use hydrochloric acid to clean up the residues after combustion. Most of them are soluble. Some carbon-containing residues cannot be dissolved in hydrochloric acid. At this time, nitric acid can be used for cleaning because nitric acid has strong oxidation. It can also be heated appropriately during cleaning.
Graphite crucibles need to be kept clean. The inside outside should be bright. After a long period of burning, the outside of the crucible may be dull. It will go deep into the inside cause the crucible to be fragile cracked. Therefore, it must be clear of unclean things. If there are still five spots the surface is black, use fine sand that has passed 100 mesh without sharp edges rubbed gently with water to restore the surface gloss.
