Product Information

However, if you like to tinker with machine parts in your garage, we would point you towards the B’laster GS or the WD-40 Specialist. Fluoride graphite is a graphite intercalation compound produced by the direct reaction of fluorine and carbon. Ruffo first reported fluorinated graphite in 1937. The study found that the interlayer bond energy of fluorinated graphite is much lower than that of graphite, and the interval between fluorinated graphite layers is also twice that of graphite layers, which has led scientists to study their lubrication properties. The delicate parts in many machines prefer dry lubricants to liquid ones. This is because the dry lubricants tend to last longer on the moving parts. Many types of machinery which contain gears and other moving parts are lubricated with graphite. Graphite is even sold in bulk amounts so large companies can buy a lot at one time and use it on their machinery. However, you’re always trading one aspect for the other, and you may want a good all-around lubricant or one that will not stain the carpet. Cleanliness

Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium. [1] If you want a cleaner lubricant, such as the 3M, you may be giving up the effectiveness to keep off dust and dirt, but if you are more interested in long-lasting protection such as with the B’laster, you may have to deal with more of a mess. Ceramics. Another application is for cases where chemically active lubricant additives have not been found for a particular surface, such as polymers and ceramics. However, it does fall short in one regard. It doesn't include a plastic straw applicator, so accurately shooting it down a keyhole is slightly obnoxious. But it does clean up nicely. There are two main types of dry-film lubricants, which are known as crystalline lattice (lamella) type structures such as Molybdenum Disulphide, Tungsten Disulphide and Graphite( DRY MOLY, DRY GRAPHITE SPRAY, etc) and Fluorocarbons such as PTFE ( DRY PTFE).

What is Graphite?

Graphite can be used as a lubricant because of its layered crystal structure. In the graphite layered crystal structure, carbon atoms form a hexagonal network of graphite layers with sp2 hybrid orbitals. The carbon-carbon bond energy belongs to a resonance σ-bond (σ-electron covalent bond). It can reach up to 627K J/mol, which gives the graphite layer strong properties; the interaction between the graphite layer and the segment belongs to the weak Van der Waals force, which is caused by the conjugate significant H-bond phase on both sides of the graphite layer. The bond energy is only 5.4KJ / mol, which is only 1/110 of the covalent σ-bond strength between carbon atoms in the segment. This structural feature determines the load-resistant, corrosion-resistant, high-temperature, and radiation-resistant characteristics of the graphite layer, as well as the excellent sliding properties between the sheets, laying a foundation for graphite as a high-performance lubricant.

We can’t help but love WD-40 Specialist more because it works perfectly, and the application bottle is better. 3. Quest Specialty Micro-Dry PTFE Dry Lubricant & Release Agent – Considered for Best PTFE As a final note, if you live in a coastal area with humid salty air, you may find better rust protection using Teflon over graphite. Final Thoughts So if you can access the surface you need lubricated, it is perfect. If you need a WD40 type lubricant that will penetrate, this product will not work well.

Synthetic graphite is a high temperature sintered product and is characterized by its high purity of carbon (99.5−99.9%). Primary grade synthetic graphite can approach the good lubricity of quality natural graphite.

Uploading

For applications where only a minor lubricity is needed and a more thermally insulating coating is required, then amorphous graphite would be chosen (80% carbon). It has excellent outdoor durability, lasts a long time, and prevents rust and corrosion, even in humid and coastal locations.

Graphite is best suited for lubrication in air. Water vapor is a necessary component for graphite lubrication. The adsorption of water reduces the bonding energy between the hexagonal planes of the graphite to a lower level than the adhesion energy between a substrate and the graphite. Because water vapor is a requirement for lubrication, graphite is not effective in vacuum. [4] Because it is electrically conductive, graphite can promote galvanic corrosion. In an oxidative atmosphere, graphite is effective at high temperatures up to 450°C continuously and can withstand much higher temperature peaks. Traditional lubricating oils are generally replaced every 5,000 kilometers, and they are not resistant to high temperatures. Many institutions around the world are studying and improving them. In the past, the additives used to enhance the performance of lubricating oils were mostly sulfur and phosphorus substances, which were eventually discharged into the air and caused pollution. Graphite oil lubricant is widely recognized as the ideal solid lubricant material due to its lubricating effect and ultra-stable physical properties. Still, even in the United States, its ultrafine and specific gravity problems have not been solved, that is, the unevenness and precipitation of graphite particles problem.

Dry-powder tumbling is an effective application method. The bonding can be improved by prior phosphating of the substrate. Use of free powders has its limitations, since adhesion of the solid particles to the substrate is usually insufficient to provide any service life in continuous applications. However, to improve running-in conditions or in metal-forming processes, a short duration of the improved slide conditions may suffice. [ citation needed] Anti-friction coatings [ edit ] The options that seem to be the cleanest are the more earth-friendly lubricants, which also utilize a more precise application process. I also used it on the rubber grommets that hold the sway bar on my car, they were squeeking. But I had to unbolt the grommet and spray the inside of the grommet and the sway bar to make it work (it completely stopped the squeeking). Without disassembly the graphite spray did not work, it dried before it could lubricate the grommet. If you have ever wondered about graphite lubricant uses, you now know how versatile it is. If you are in need of a lubricant but think a liquid one may be too messy or just will not cut it, consider using graphite as a dry lubricant.

However, a layered crystal structure alone is not necessarily sufficient for lubrication. In fact, there are some solids with non-lamellar structures that function well as dry lubricants in some applications. These include certain soft metals ( indium, lead, silver, tin), polytetrafluroethylene, some solid oxides, rare-earth fluorides, and even diamond. [2] Graphite is structurally composed of planes of polycyclic carbon atoms that are hexagonal in orientation. The distance of carbon atoms between planes is longer and, therefore, the bonding is weaker.

A Lubricant is a substance that when applied in a thin layer to an item or machinery, reduces friction, heat, and wear between the solid surfaces that are in contract with each other. By having the right and appropriate Lubricant, the friction and wear for the materials can be controlled, therefore, providing a reliable operation within the workplace, in the long run, will save you money on maintenance. Limited interest has been shown in low friction properties of compacted oxide glaze layers formed at several hundred degrees Celsius in metallic sliding systems. However, practical use is still many years away due to their physically unstable nature. Graphite has been developed as a dry powder lubricant for a long time. It has been reported that the use of graphite in vehicle engines has a good effect of saving fuel at about 10%. With the development and popularity of nano engine oil additive, nano-materials have been widely used in solid lubricants and have shown better lubricating properties than traditional materials. The flake nano-graphite studied by Dr. Huang et al. As a lubricant additive. Graphite is more natural to spread into a film on the surface of the friction pair and shows better lubricity than ordinary graphite. In crystalline form structures such as DRY MOLY and DRY GRAPHITE, the shear forces between opposing layers are weak resulting in lubricity between sliding surfaces.
