What is graphite emulsion?

Graphite emulsion, also known as graphite colloid, is a colloidal material mainly composed of graphite and cellulose. It is classified into

 solvent-based and water-based types and is named for its emulsion form. It features heat insulation and cooling, high-temperature

 adhesion, and chemical stability. As a lubricant and mold release agent, it is widely used in forging, metal processing, and other

 industries, which can extend the service life of molds by 1-3 times and improve the quality of forgings.

Based on the conductive and lubricating properties of graphite, this material has been developed for multiple applications, including

 conductive coatings, electromagnetic shielding agents, and anti-corrosion sealants, and is used in the manufacturing of electronic

 devices, chemical anti-corrosion, and other industries. Since the 1990s, water-based forging graphite emulsion and other products

 have gradually replaced imports, with technical indicators reaching international standards and obtaining ISO9001 certification for

 export. With the optimization of the process, its application scenarios have expanded to precision manufacturing fields such as

 vacuum coating and tungsten wire drawing. Its environmental friendliness and ease of operation have further promoted its industrial

 popularization.

Forged graphite emulsion is unanimously regarded by the forging industry as a new type of highly efficient lubricating and demolding

 material for domestic production at present. It has a good heat insulation and cooling effect on molds, and can extend the service life

 of molds by 1-3 times. It has excellent lubricity, demolding performance, chemical stability, high-temperature adhesion, and can

 improve the service life of molds and the quality of forgings. It does not pollute the environment and is easy to use.

There are many types and applications of graphite emulsions. The technology of graphite emulsions integrates knowledge from

 multiple disciplines. A series of graphite emulsions produced based on the electrical conductivity, lubrication, anti-corrosion, and high-

temperature resistance characteristics of graphite can be widely used in fields such as conductivity, electromagnetic shielding, anti-

static, forging, lubrication, anti-corrosion, sealing, screen printing circuits, and color display device manufacturing, playing roles such

 as conductivity, anti-static, anti-corrosion, lubrication, sealing, and shielding.

method of application：

1. Before use, stir the forged graphite emulsion thoroughly. After prolonged storage, a small amount of solid substances mayprecipitate in this product. However, after stirring, it can return to the original uniform suspension state without reducing theperformance.

   
   

2. Users can decide whether to dilute the original liquid and the dilution ratio according to different requirements or experience. The

 following ratios can be referred to as a reference:

(1) For complex-shaped forgings with difficult demolding, large-scale ones should be diluted 3-5 times with water; medium and small-

sized ones should be diluted 5-10 times with water;

(2) For general forgings and precision gears, they should be diluted 5-15 times with water;

(3) For roll forging processes, it can be diluted 20-30 times;

(4) For special process requirements, no dilution is necessary and the product can be used directly.

3. To ensure the coating effect, it is required to use automatic or manual graphite emulsion spray guns for spraying. When using, dilute

 the forged graphite emulsion to a certain multiple with tap water and load it into the graphite emulsion spray gun storage tank

 (graphite atomizer). Spray the mist on the mold through 0.3-0.6 Mpa compressed air. When the graphite emulsion spray gun is not used

 for a period of time, clean the remaining graphite emulsion in the spray gun, pipe, and nozzle with clean water to avoid graphite

 emulsion precipitation and blockage of the pipeline. When using it again, check if it is unobstructed and shake the graphite emulsion

 liquid evenly to prevent precipitation. The flow rate of the graphite emulsion spray gun should be determined according to the forging

 process, generally 40-60 milliliters per second.

To achieve better demolding effect, it is best not to use the manual application method. This method not only results in uneven

 coating, affecting the lubrication and demolding effect, but also wastes a lot of graphite emulsion.

4. After using the forged graphite emulsion, keep it sealed, store it at room temperature, and avoid exposure to the sun. Pay special

 attention to warmth preservation in winter to prevent freezing.
