K2 graphite Lubricant Spray, Graphite, Graphite Spray Graphite Lubricant, 400ml

Product Information

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. We love that it goes on clear, unlike many dry lubricants, which can leave a residue. This also means it can be difficult to see where it has already been applied, but we think the tradeoff is fair. 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.

Hexagonal boron nitride is a ceramic powder lubricant. The most interesting lubricant feature is its high temperature resistance of 1200°C service temperature in an oxidizing atmosphere. Furthermore, boron nitride has a high thermal conductivity. (Cubic boron nitride is very hard and used as an abrasive and cutting tool component.) We independently review everything we recommend.

If you need a WD40 type lubricant that will penetrate, this product will not work well.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 Dry-film lubricants can also be used in ceramic applications for cases where chemically active lubricant additives have not been found for a particular surface, such as polymers or ceramics. 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.

Graphite is a traditional dry powder lubricant. The application of graphite in oils has significant economic benefits and has many advantages. With the development of science and technology and the deepening of scientific research, graphite lubricating materials have expanded to appear in the form of graphite derivatives, such as flake nano-graphite, expanded graphite, fluorinated graphite, and compound or straightforward intercalated graphite.The layered structure, and because of the effect of the intercalation substance, makes the layer spacing significantly increased, which is hugely beneficial to the improvement of lubrication performance. 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. It has excellent outdoor durability, lasts a long time, and prevents rust and corrosion, even in humid and coastal locations. Also, the benefits of dry-film lubricants can be applied to instances where lubrication is required in a high-temperature environment or where there is an oxidising atmosphere. Liquid lubricants such as oil and grease will typically not survive these conditions.The most common types of dry lubricants you'll find are graphite, PTFE, silicone, and Teflon (branded PTFE). 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, 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. 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]

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

What Lubricants are Best for Locks?

Extruded graphite is a loose and porous worm-like graphite obtained from natural flake graphite by intercalation, washing, drying, and high-temperature expansion. Studies have shown that in lubricating oils, expanded graphite shows excellent compatibility with oil media. 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. Most reviewers have been very happy with this lubricant and we understand why. It worked great for everything we tested it on, and we will buy another bottle when this one runs out. High temperature. Graphite and MoS 2 act as lubricants at high temperature and in oxidizing atmosphere environments, where liquid lubricants typically will not survive. A typical application involves fasteners that are easily tightened and unscrewed after a long stay at high temperatures.

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. Polytetrafluorethylene (PTFE) is widely used as an additive in lubricating oils and greases. Due to the low surface energy of PTFE, stable unflocculated dispersions of PTFE in oil or water can be produced. Contrary to the other solid lubricants discussed, PTFE does not have a layered structure. The macro molecules of PTFE slip easily along each other, similar to lamellar structures. PTFE shows one of the smallest coefficients of static and dynamic friction, down to 0.04. Operating temperatures are limited to about 260°C. 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 ]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. Dry film lubricants are an attractive alternative to fluid lubricants because they minimise friction and prevent seizing and galling, especially in extreme applications where fluids may freeze or vaporise. For instances where traditional lubricants, like oil or grease, can undergo a state change (i.e. freeze) and thus no longer provide protection, a dry-film lubricant will remain intact and provide continuous lubrication and protection.
