Castor and soybean can extract environmental protection medium

"Water, mechanical oil, brine, nitrate and other media are used for traditional heat treatment and quenching When water is used as quenching medium, it is easy to deform and discard the workpiece, while mineral oil, salt water and nitrate will pollute the environment when they are used as quenching medium We have been focusing on the research and development of efficient and environmentally friendly heat treatment media, and achieve good quenching effect " Xu Jiajun, director of public relations of Nanjing Kerun industrial media Co., Ltd., told reporters Is there such a media with the best of both worlds? In Nanjing Kerun, the reporter walked into the "birthplace" of magic media In the R & D area of the company's products, the neat shelves are filled with various white bottles, which are exactly the medium of the company's R & D Liu Hao, head of the project team of the R & D Department of the enterprise, pointed to the shelf and introduced to the reporter: "white plastic vials contain additives for water-soluble media, while plastic buckets contain oil media." The so-called water-soluble product is a kind of water-soluble quenching medium, which is made of water as raw material and compounded with additives; the oil product is a kind of quenching oil compounded from base oil The two kinds of medium have their own characteristics: water soluble quenching medium has the advantages of fast cooling speed, low price and wide source, which is suitable for workpieces with large section size, simple shape and high performance requirements, while quenching oil is generally used for key parts that are easy to deform The key point of water-soluble quenching medium is to add the additive The additive is a kind of composite polymer component Xu Jiajun said with a smile: "this additive is like the secret formula of Coca Cola As long as the additive formulated by formula is added into the water, a magical water-soluble medium is born." "Magic" in his words refers to the technological innovation of products According to reports, this water-soluble medium can be used to cool the crankshaft of high-speed ship, breaking the technical bottleneck of good cooling effect of traditional clean water, friendly environment, but easy to crack "The difficulty of this technology lies in not only ensuring enough high-temperature cooling speed, making the quenching and cooling effect of the parts good, but also controlling the low-temperature cooling speed of the medium, preventing the parts from cracking, achieving uniform cooling, and effectively controlling the forging without distortion." For oil agent medium, Nanjing Kerun innovatively uses vegetable oil instead of mineral oil, "we can extract oil from castor, soybean and other plants to develop oil agent medium The biggest advantage of using "vegetable oil" is low carbon and high performance, which can reduce the emission of harmful substances and be green and environmental friendly "
