Wiredrawing graphite milk graphite milk is divided into MD and S series products. MD series graphite emulsion is a release agent for metal forging. Such as release agent for steel forgings, copper forgings, alloy forgings and aluminum forgings. It can also be used as a lubricant for extruded profiles. S series graphite emulsion is used as drawing lubricant. Such as tungsten wire, molybdenum wire, rhenium wire, thorium wire and other lubricants. Wiredrawing graphite milk (I) conductive coating: the conductive coating is mainly made of ultra-fine graphite powder with excellent conductivity and lubrication performance as filler, organic plastic resin as adhesive, organic solvent with good volatility as carrier, adding appropriate dispersion and suspending agent, and finishing, The main technical indicators are shown in table 3-1 table 3-1 main technical indicators of conductive coatings project indicators main uses solid matter ≥38% high energy alkaline, the coating layer of conductive corrosion on the inner wall of zinc manganese battery shell can withstand the long-term corrosion of 40% potassium hydroxide. Graphite content ≮ 32% less than 5um in graphite ≥ 90% volume resistivity 1.9m Ω. Cm (II) MD series Forged graphite emulsion: MD series graphite emulsion, It is unanimously recognized by the forging industry as a new type of high-efficiency lubricating demoulding material produced in China at this stage, which has a good heat insulation and cooling effect on the mold. It can prolong the service life of the mold by 0.5-0.3 times. It is non-toxic and smokeless in use, has no corrosive effect on the mold and parts, and has no pollution to the environment. It is ideal to improve working conditions, improve the quality of forgings, and easily obtain good forging finish. Unlike other lubricants Compared with demoulding materials, it has the advantages of low cost, simple operation, convenient use, etc. the economic benefits are very obvious, and the mold cost and lubrication demoulding can be reduced by 37-50%, Table 3-2 main technical properties and application scope of MD series Forged graphite emulsion specification and model solid content ≮% graphite ≮% sedimentation% (diluted with 20 times water for 3 hours) application scope MD-2 28 20 35 die forging of automobile and tractor parts, gear and precision forging, Roll forging md-3 30 25 undiluted molten steel casting nozzle sliding plate lubricant MD-4 35 25 undiluted pure silicon smelting MD-5 undiluted copper product precision forging release agent md-7 40 25 40 light alloy extrusion processing md-8 30 23 35 heavy forging press die forging md-10 35 26 undiluted bullet / cartridge case hot extrusion processing md-12 30 23 35 forging graphite emulsion for hammer forging: 1. Within the forging temperature range, It has good lubricity and demoulding performance. For example, the die forging process with no ejector for large forgings can be sprayed once and stamped for many times; 2. It has a good heat insulation and cooling effect on the mold, promotes the continuous hardening of the mold surface, improves the heat resistance and compression resistance of the mold, so it can increase the service life of the mold by 0.5-3 times; 3. Under high blast condition, the lubricity is quite good, the film formation is uniform, and the metal forming conditions are improved, so the quality and surface finish of forgings can be improved, and the yield and grade of forgings can be improved; 4. It has good chemical stability and suspension, does not decompose and deteriorate after long-term storage, and has no corrosive effect on workpieces and molds; 5. It does not decompose and burn under high temperature. The preparation itself is non-toxic. It does not produce toxic substances or harmful gases during work, does not pollute the environment, and improves working conditions; 6. Dilution is simple, easy to use and convenient for mechanical spraying. Usage: 1. The milk should be stirred evenly before use. After the product is placed for a long time, a small amount of solid matter may precipitate, but after stirring, the original suspension can be restored to a uniform state without reducing the use effect. 2. The user can decide whether to dilute the original solution and the dilution factor according to different requirements or experience. The following ratio is for reference; (1) if the forging is complex in shape and difficult to demould, the large forging shall be diluted by 3-5 times; Medium and small-sized water dilution 5-10 times; (2) general forgings and gear precision forging are diluted 5-15 times with water; (3) roll forging process can be diluted by 20-30 times; (4) for special process requirements, it can be used directly without dilution. 3. In order to ensure the coating effect, it is required to use automatic or manual spray guns. During use, dilute the graphite emulsion to a certain multiple with tap water, put it into the liquid storage tank of the spray gun, and spray the mold in mist form with 0.3-0.6mpa compressed air. When the spray gun is not used for a period of time, the residual graphite of the spray gun, pipeline and nozzle should be washed clean, In order to avoid graphite precipitation blocking the pipeline, it is necessary to check whether it is unblocked and shake the lotion evenly to prevent precipitation. The flow rate of the spray gun is determined according to the requirements of the die forging process, generally 40-60ml / S. in order to obtain a good coating film, it is better not to use the method of manual coating. In that way, not only the coating film is uneven, which affects the lubrication and demoulding effect, but also the yield and cost of the graphite emulsion are large. 4. Pay attention to sealing the graphite emulsion after use, Store at normal temperature, do not expose to the sun, and pay attention to keeping warm in winter to prevent freezing. (III) drawing graphite emulsion: variety: S-0 S-1 s-1b performance: it has good lubricity, high temperature adhesion, oxidation resistance and non-toxic, Extend the service life of the die.
