With the development of industry, the demand for molds is getting larger and larger, and the life of molds is getting more and more attention. In the production, many molds are easy to damage, requiring frequent sharpening and repairing, which seriously affects the production schedule and product quality. 823 mold special anti-wear agent is one of the series of products of DJB-823 Solid Film Protectant (National Military Standard GJB-1300-91) invented by Professor Peng Daoru of Institute of Chemical Protection, Beijing University of Posts and Telecommunications. The product is corrosion-resistant, has good lubrication performance and wear resistance, can improve the life of the mold by 3 to 10 times, and has low cost, simple operation, short cycle and quick effect. First, product features 1. Organic compounds : 823 anti-wear agent is an artificial organic compound with two special structures and a combination of lubricant and metal corrosion inhibitor. The composition is a strong polar molecule having a permanent dipole moment, and can form a chemical bond with the empty orbit of the metal atom through the electrostatic field force and the coordination field force of the molecular end group, and the binding force is 30 to 150 kcal. /mol, 11 to 300 times greater than the intermolecular binding force. 2. Polar molecules : Polar molecules consist of a head and a tail. There are dense electron clouds in the head of the polar molecule. The electrons with larger energy enter the empty orbit of the metal surface and form chemical bonds (covalent bonds and coordination bonds) with the metal atoms. Very strong polarity. The tail has a strong self-lubricating property, which plays a role in lubrication and wear resistance. 3. Mechanism of action : a, anti-corrosion : The metal surface of the 823 anti-wear agent is applied to form a complete protective film. This film is composed of a myriad of polar molecules arranged in a row to form a solid film that isolates the contact of media such as air and moisture on the metal surface and exhibits excellent corrosion resistance. b, lubricity : The mutual movement of the two metals coated with the 823 anti-wear agent is actually the friction between the tail and the tail of the polar molecule of the 823 anti-wear agent riveted on the metal surface, forming a friction between the non-metal and the metal. c, wear resistance : The metal surface coated with the 823 anti-wear agent can form a multi-molecular structure, generally having 3 to 4 layers and a thickness of about 20 nm. If more than 4 layers, the 823 anti-wear agent molecules cannot be aligned to form a physical adsorption layer. The multi-molecular structure of the 823 anti-wear agent coating forms a friction between the film and the film, and the coating and the non-coating increase the wear resistance by 11.09 times. d, easy to use : 823 anti-wear agent process is simple, after the workpiece is processed and put into the 823 solution for 1 to 3 minutes to remove and dry to form a dense dry protective film, about 1 ~ 2 microns thick. The film layer does not affect the dimensional accuracy and inherent physical properties of the workpiece. e, low cost : The 500 ml solution can be applied to a surface area of ​​5 to 7 square meters, and the coating cost is about 0.2 to 0.5 yuan per square centimeter. f, a wide range of applications : The 823 anti-wear agent process is suitable for a variety of metal materials, not only on the surface of steel products but also on the surface of powder metallurgy and cast iron parts to form a uniform thickness, dense structure of the protective layer. Widely used in the surface treatment of non-ferrous metals and non-metallic materials such as steel, cast iron, steel pipes, steel plates and gold, silver and copper. g, high bonding strength : 823 anti-wear agent and metal base parts have high bonding strength, no skin, no falling off, no rust; not only maintain the original mechanical properties of the metal base, but also increase the wear resistance and corrosion resistance. h, uniform coating : The 823 anti-wear agent coating is even and dense. Whether it is a shallow hole, a deep hole, an inner wall of a pipe, a corner of a product, or the like, the surface can be uniformly treated with a surface treatment without pitting or pores. 823 anti-wear agent can meet 16 performance indexes such as lubrication, wear resistance, electrical conductivity, insulation, moisture proof, mold resistance, salt spray prevention, hand sweat resistance, impact resistance, industrial atmosphere resistance and high and low temperature resistance. Its comprehensive performance indicators meet or exceed the technical performance indicators on the literature collected by the National Patent Office and the National Science and Technology Commission Information Center, and are ranked at the international advanced level. Second, improve the wear resistance of the mold Dies such as punching and drawing are repeatedly rubbed in production, and their wear resistance must be increased to extend the service life. If new materials, new surface treatment methods, etc. are used, there are disadvantages such as high cost, complicated process, and long production cycle. 823 anti-wear agent forms a covalent bond with ferrous metal atoms such as Cr12, CrMoV, T10A, and its binding force is 30-150 kcal/mol, which is 11-300 times larger than the intermolecular binding force (ie van der Waals force). Although it is subjected to a strong process force during the stamping process, it does not cause the coating to fall off. The metal surface coated with the 823 anti-wear agent can form an aligned multi-molecular structure, generally 3 to 4 layers, and having a thickness of about 20 nm. The multi-molecular structure of the 823 anti-wear agent coating forms friction between the film and the film; it is applied to cold-punching dies such as punching, drawing, bending, die-casting, etc., which can greatly improve their wear resistance and the effect is remarkable. a, reduce the number of times the mold is sharpened; save labor, save time, and reduce labor intensity. b. Make the workpiece size stable and greatly improve the qualified rate of the product. c. Extend the life of the mold by 3 to 10 times, reducing the cost of the mold material and the manufacturing cost. Third, to ensure good lubrication In the stamping process, due to the strong friction, it is necessary to add high-strength special lubricating oil to reduce the friction coefficient and reduce friction to improve the quality of the workpiece and extend the life of the mold. At present, there are many ways to improve the hardness of the mold surface, such as surface quenching, hard chrome plating, nitriding treatment, etc., but these methods have a common shortcoming, that is, can only improve the hardness of the mold surface, but can not reduce the surface friction coefficient. And reduce friction. When the surface of the mold is coated with 823 anti-wear agent, a complete protective film is formed on the surface of the mold. This film is formed by a series of polar molecules of anti-wear agents. The mutual movement of the two metals coated with the 823 anti-wear agent is actually the friction between the tail and the tail of the polar molecule of the 823 protector riveted on the metal surface, has good self-lubricating properties, and is resistant to seizure (bonding). It can reduce the friction coefficient between the workpiece and the mold by 5 to 10 times and reduce the friction by more than 1/3. a, improve the quality of the workpiece section, reduce burrs. b. Reduce the surface roughness, make the surface of the product bright, do not pull flowers, and do not crack. c. It can make the blanking smooth and avoid blockage. d. The effect on the mold used for mass production is remarkable.
