Grease graphite: all the secrets of a chemical

Among the huge number of all kinds of lubricants is not the last place is a graphite lubricant. Its application has a strictly delineated area, which is due to its properties.

About graphite in a nutshell ...

Its name received this product from the substance of the same name, Included in its composition. It is he who imparts certain properties to the lubricant. What is graphite? This substance is gray, although it differs in a variety of shades - from black to silver. Has a metallic greasy sheen. Has the ability to form thin films if you rub them a hard surface. It is based on the lubrication used in various industries.

Graphite grease: features and properties

GOST 3333 80 Graphite grease - this is how the substance is indicated in the nomenclature sheets of the enterprises. For its production, colloidal graphite preparations are used. In fact, such a lubricant is nothing but oil oil, which is thickened with calcium soap. The graphite, which gave the name to the substance, is only 10%. In appearance it is a homogeneous mass that has a black or dark brown color. Grease graphite in its composition is almost identical to the solidol. The difference lies in the addition of graphite and the use of a more viscous oil, on the basis of which the substance is produced.

Graphite grease has the following properties:

• It does not evaporate even at a temperature of +150 degrees.
• It is not corroded, therefore it protects the workpiece from rust.
• In the composition of this substance is not more than 3% of water.
• Its use is recommended at temperatures from -20 to +70 degrees. And in some springs the temperature regime is allowed and below - 20 degrees.

Application of graphite grease

Lubricant graphite is used today in many spheres of production:

1. Most often it is used for slow-moving heavy machinery. In the suspension of tractors, in the springs, in the supports of the drill bits (those same diamond heads that produce oil), in gears. In all these mechanisms, the increase in resistance, which is caused by lubrication, does not play any role. But for exact details, such as bearings, this tool is not suitable. It can lead to component damage or wear. This is facilitated by the mechanical impurities that make up graphite.
2. Grease graphite can be used for preventive purposes. For example, it is processed in the winter, the usual locks. Thus, they do not freeze and open well. All kinds of additives in the composition of the drug contribute to the dissolution of ice and the removal of rust, thereby protecting the lock mechanism.

When choosing this lubricant, you need to be very careful, since cases of fakes have been observed quite often lately. Therefore, preference should be given to the product, which produces well-known firms with a good reputation. And to make purchases preferably in specialized stores. Because the quality of this material depends on the stable operation of equipment for various purposes.
