Graphite emulsion is in milk state and its main component is micro powder graphite. Strictly speaking, it should be called as graphite colloid, it is a black paste with a slight ammonia odor and is easily dispersed in water. We have both forging graphite emulsion and conductive graphite emulsion for you to choose from. Here, we'd like to introduce these graphite emulsion products in details as well as how to use them.
Forging graphite emulsion is a kind of highly dispersed colloidal graphite emulsion. It takes high carbon graphite as raw material and then obtain high-purity, ultra-fine natural flake graphite powder after ultra-micro grinding. It is formulated with water as carrier and added with appropriate suspension dispersing agents, emulsifiers, stabilizers, colloidal protective agents and other chemical additives. It has good lubricity, demolding, chemical stability, high-temperature adhesion properties, and can extend the service life of molds and dies and improve the quality of the forging parts. It is environmentally friendly and easy to use. As a result, it is an ideal high temperature mold release lubricant for ferrous and non-ferrous metal thermal processing, and is widely used in forging and metal forming industry.
Forging graphite emulsion has a wide range of applications, including:
Conductive graphite emulsion can be used for cable outer sheath surface coating, and can form a uniform, continuous conductive coating film on the outside of the sheath. It is a conductive graphite coating that uses high-purity, ultra-fine natural flake graphite as the conductive medium, with polymer materials as the main binder, and a certain amount of inorganic materials as modifiers.
It uses water as the dispersing medium. It neither uses environmentally harmful substances, nor contains heavy metals. It is an environmentally friendly conductive coating. The film formed after drying has a smooth, glossy surface, with good conductivity, adhesion, and moisture resistance, and can be used in humid environments.
Before use, stir the forging graphite emulsion evenly. There may be a small amount of solid sediment after long time of placing, but it can be restored to the original suspended uniform state after stirring without reducing the using effect.
Users can decide whether to dilute the original solution and the dilution ratio based on different requirements or experience. The following ratios are for reference.
Before use, stir the conductive graphite emulsion evenly and then it can be used directly. If you feel high viscosity when using, you can add pure water to adjust to an appropriate viscosity. Conductive graphite emulsion has a good coating performance. Before coating, keep the surface clean, especially free from oil stains. The places with oil stains may not be coated. After coating, it dries quickly and forms a film at a temperature of 80–100 °C.
After using the graphite emulsion, thoroughly rinse the residual graphite emulsion in the spray gun, pipeline and nozzle, to avoid the graphite emulsion from precipitating and clogging the pipeline. When using the spray gun again, check if the gun is unobstructed or not, and sake the graphite emulsion evenly, to prevent it from precipitating.It should be noted that the graphite emulsion shall be well sealed and stored at room temperature, and shall not exposure to the sun. In the winter, especially pay attention to keep it warm, to prevent freezing.
