Cutting fluid for the future development trend

2021 - cutting fluid for the future development trend 02 - 19 in the case of cutting fluid, according to the present situation of metal processing to analyze, the focus of the future research and development of cutting fluid in the protection of basic indicators to improve the basis of development in the direction of a single one or several special functions, in order to meet the specific requirements of metal machining. Antirust function in terms of antirust function, pay particular attention to under the condition of high temperature and high humidity on antirust effectiveness of metal workpiece ( In recent years due to the greenhouse effect intensifying, in southern China in summer high temperature and high humidity phenomenon also intensified into a situation) , solved should stress on in the direction of the cutting fluid in the metal processing surface anti-rust film formed by water resistant effect of the above, the solution of the two main paths, one is to make the surface passivation anti-rust film crystals is more compact, and have very low solubility product constant, so as to better prevent water infiltration, so as to block of metal surface galvanic cell reaction; Also for emulsion type cutting fluid, part of antirust effect of cathodic protection from emulsified oil, so forming a protective film for the resistance to secondary water soluble will be critical need to solve. And extreme pressure lubrication function in lubrication and extreme pressure function, conventional micro emulsion and emulsified cutting fluid can all basic guarantee the demand of modern machine tools, but due to its for deterioration is difficult to control, but also because in use process prone to working fluid viscosity increases gradually and makes filtering difficult wait for a phenomenon, people are more likely to find a high lubrication, high extreme pressure all synthetic cutting fluid, it is also currently in the field of research and development of cutting fluid, one of the top issues for traditional polyether type water-soluble lubricant, low lubricating effect and higher prices make this kind of product can't meet the requirements, need a different approach to materials and success can be more powerful monomer. Effluent treatment in terms of environmental protection, as the country of the implementation of the compulsory industrial wastewater zero emissions requirements, the cutting fluid cycle working liquid waste water processing of feasibility and operability that become a realistic problem in front of us, so the cutting fluid manufacturers in product development will have to consider this problem, say, the use of anion more easily than non-ionic post-processing, therefore the development of multifunctional powerful anionic surfactant is extremely important. Raw material composition improvement direction in addition to cutting fluid in low toxicity, low irritation and low odor, in recent years, people's demand is also more and more high. In the understanding of cutting fluid toxicity, a lot of people there is a wrong concept, thought that the greater the smell its toxicity, the greater the in fact, there is no connection between the two, but obviously excitant odour will bring people uncomfortable, at least not the joyful feeling, therefore also need attention. Develop a good cutting fluid, also need to performance of the monomer of raw material supply. Raw material continuously in recent years, although there are a lot of monomer was developed, but most just simple modification on the molecular structure of the traditional raw materials or products for better purification, few revolutionary improvements on the molecular structure of the traditional raw materials, product research and development hindered large cutting fluid. One of the future improvement direction of the cutting fluid raw material will be the natural biological molecular material for artificial chemical modification, such as to chemical grafting of natural protein hydrolysate, the resulting material not only is it more safe environmental protection, also often give strong physical and chemical indicators to cutting fluid. The future trend of cutting fluid throughout the cutting fluid market of the 21st century, some new cutting technology and the corresponding products have appeared. In the face of human environmental protection consciousness enhancement, the market is more and more high to the requirement of cutting oil performance of green environmental protection. Such as the use of biodegradable, does not contain aromatic hydrocarbon polyolefin composite materials instead of mineral oil as base oil, cutting oil substitute tungstate and molybdate for water base cutting fluid in the prevention of toxic additive method promoted gradually. The pursuit of efficiency and production quality is an eternal subject of industrial, performance excellence, stability, use cycle is long and lasting cutting fluid products is also gradually favored by users. Although this kind of production quality and the price is expensive, but the market users also get used to comprehensive accounting of the cost of production, in order to measure cutting fluid performance of the products. As the processing and classification is more and more thin, the development trend of cutting fluid has not standardized. In view of the high speed grinding, for example, some enterprises has developed high performance grinding oil, which changes the past mode of operation in cutting fluid instead of grinding oil. Besides, there are the liquid nitrogen as cutting fluid, selecting the appropriate dosage of cutting fluid in order to achieve the best effect of cutting, dry cutting, etc. New technology. In terms of overall trend, new cutting technology will be in pursuit of high efficiency, high performance, low pollution and low energy consumption as the goal, lead cutting fluid technology continuous development. （ Source: shaft research website)
