The role of rust inhibitor in metal working fluid

the role of metal working fluid is to reduce the loss of expensive equipment caused by high temperature and friction and ensure the stability of component performance. For industrial metal processing manufacturers, these processing fluids play a vital role in maintaining the good operation of equipment

synergistic additives are important components that constitute water dilution, water-soluble oils, and synthetic/semi synthetic metalworking fluids and give them functionality. The common types of such additives are dispersants, stabilizers, rust inhibitors, emulsifiers, pH buffers, neutralizers, etc

due to the harmful corrosion of aluminum alloy and galvanized steel caused by water-based metal working fluid in use, the demand for anti-corrosion additives is increasing. Aluminum alloy and galvanized steel are widely used. The strength limit is an important index to measure the strength of materials in the field of automotive and aerospace manufacturing In fact, the intention is that the working stress should not exceed the strength limit of the material, otherwise it will break and even cause serious accidents All have applications. As developed countries and emerging economies have strong demand for these products, the market demand for metalworking fluids that do not damage the appearance of final parts also increases

formation of corrosion

various additives such as water and amino alcohol will cause the reaction between the surface of aluminum alloy and galvanized steel to produce corrosion. The rust is usually black, white or gray. The common alkaline environment of metal working fluid will generally dissolve the protective oxide layer on the surface of aluminum alloy [1]. In addition, the optical action of some tap water and natural water with oxide film will also produce black or brown rust [2]. There are also some complex factors that can lead to corrosion, such as magnesium, chloride ions and carbonate in the alloy composition

ensure that the parts are free of corrosion

in order to ensure that the parts are not damaged by corrosion, metal working fluid with multi-functional additives should be used. Research and formulate suggestions for accelerating the transformation and upgrading of agricultural mechanization and agricultural machinery and equipment industry. In addition to preventing the formation of rust, it also has the advantages of improving performance. Angus chemical company, a subsidiary of Dow Chemical Company, recently launched a unique multi-functional anti-corrosion additive corrguardtm Si, which can effectively prevent the corrosion of the surface of general aluminum alloy and galvanized steel, make up for the defects of materials, and thus meet the strong demand of customers for such products

Figure 1 0.1% of corrgard Si in pH although it is necessary to build institutions such as laboratories, it is not enough to have wood-based panel universal testing machine alone. The effect presented in tap water with a value of 9.5

in order to prove the effectiveness of this product, the aluminum alloy and galvanized steel are partially immersed in water with pH detection control, semi synthetic and synthetic processing fluids containing corrgard Si and non corrgard Si (tested independently). When 0.1% corrgard Si was added, the corrosion of the immersed part disappeared

corrgard Si is unique in that it can form a single molecule protective layer on the metal surface, thereby inhibiting the formation of rust. This process will not produce silicate and phosphorus, and is very suitable for long-term anti biological formula. This product can take effect at a low concentration of 0.1%. It has good safety and environmental protection, and the waste produced is also easy to deal with. Corrgard Si also has emulsifying and lubricating effects

the effect of orguard Si in the synthetic processing fluid with pH value of 9.3 to establish and improve the comprehensive evaluation criteria of plastic granulator equipment and industry standards

orguard Si is more resistant to microbial degradation than phosphorus based aluminum rust inhibitor. Because it does not contain silicate, it will not invalidate the ultrafiltration membrane

corrgard Si is relatively non-volatile and will not cause significant volatile organic compounds release in metal processing fluid manufacturing or processing fluid using factories

one of the properties of multifunctional additives is rust prevention. This versatility reduces the demand for other additives, thereby controlling the cost. Additives have various performance advantages required for high-quality finished products
