In the field of modern industrial operation and maintenance and metal processing, rust prevention and safety are always the two core propositions. On the one hand, the exposed metal surface is highly susceptible to moisture, salt spray and chemical gas erosion, forming rust, affecting the accuracy and life; on the other hand, traditional anti-rust oils are often accompanied by high viscosity, low flash point and other drawbacks. Not only is it difficult to apply and cumbersome to clean, but it also buries serious safety hazards in high temperature or open flame operating environments. How to find an oil that can not only prevent rust efficiently, but also take into account safety and convenience has become an urgent need for many equipment managers and process engineers. Hank BS-400 series anti-rust oil is an innovative solution to this pain point. With its excellent characteristics of low viscosity and high flash point, it achieves the perfect balance of "safety" and "rust protection", providing reliable, economical and reassuring protection for scenarios such as precision manufacturing, automotive parts, hydraulic systems and long-term storage.
Low viscosity: fast penetration, thin oil film, cleaner workpiece
Traditional anti-rust oils often have poor fluidity due to high viscosity, making it difficult to penetrate into hidden parts such as workpiece gaps, blind holes and hinges. During operation, a large amount of brushing or soaking is often required, and the oil film is thick and uneven, which not only wastes materials, but also easily leaves sticky ash during subsequent assembly or packaging, which affects the appearance and assembly accuracy of the product. Hank BS-400 series adopts a special refined base oil and a composite anti-rust additive formula, which has a very low kinematic viscosity at room temperature. Similar to light lubricating oil, it can quickly penetrate into the microscopic rough structure of the metal surface and the internal gap of the part, forming a continuous and uniform molecular-level protective film.
The direct advantages brought by low viscosity are reflected in three aspects: First, the coating method is flexible, suitable for both soaking, spraying, and manual brushing, especially for complex-shaped workpieces, with its excellent fluidity, it can easily cover all key surfaces without repeated operations. Second, the oil film is extremely thin and non-stick to the hand. After the workpiece is taken out, the surface is refreshing, and the amount of oil is small. It is more convenient to follow up degreasing or direct assembly, effectively reducing the cost of the process. Third, low viscosity means lower adhesion resistance. For precision parts that need to be oiled and cleaned frequently, such as bearings, gears, guides, etc., it can significantly reduce oil residue and avoid affecting the tolerance fit. In addition, due to the thin and uniform oil film, the oil consumption per unit area is significantly reduced, and long-term use can save enterprises considerable procurement and processing costs.
High flash point: eliminate fire hazards from the source
In the vicinity of welding, cutting, heat treatment or high-speed equipment, the flash point of oil directly determines the safety level. The flash point of traditional anti-rust oils is often lower than 180 degrees Celsius, and it is easy to ignite in the event of open flames or high-temperature heat sources. In the event of leakage or oil mist accumulation, the consequences are unimaginable. The Hank BS-400 series increases the flash point to more than 220 degrees Celsius by selecting high-boiling base oil components and optimizing the additive system, which is much higher than most congeneric products. This means that in conventional industrial environments and even in some high-temperature areas, the BS-400 will not easily produce flammable steam, greatly reducing the risk of fire and explosion.
The high flash point not only brings the safety bottom line, but also gives the operation flexibility. For example, in the machining workshop, the workpiece still has a high residual temperature after the turning and milling, and the ordinary anti-rust oil may smoke or burn, while the BS-400 can be applied while it is hot, and the residual temperature of the workpiece can be used to quickly spread the oil to achieve instant rust prevention. At the same time, in the fire inspection or occupational health and security evaluation, the use of high flash point oil can help enterprises more easily pass compliance requirements and reduce the investment in special storage and ventilation facilities. Workers no longer have pungent odors and burning fears when operating, and the working environment is more comfortable and secure.
Anti-rust performance: long-term protection against complex environments
Low viscosity and high flash point do not come at the expense of anti-rust performance. The Hank BS-400 series adds a variety of polar corrosion inhibitors, which can form a strong hydrophobic adsorption layer on the metal surface, effectively isolating the intrusion of oxygen, water and electrolyte ions. This dual role of chemical adsorption and physical coverage makes it pass the neutral salt spray test and the wet heat box test. It can provide anti-rust protection for up to 12 to 24 months in indoor storage environments. Even in high-humidity, salt spray coastal areas or under sea conditions, it can significantly delay the formation of red and white rust.
Unlike other low viscosity anti-rust oils, the BS-400 series also has excellent compatibility with ferrous and non-ferrous metals. Whether it is cast iron, carbon steel, alloy steel, or copper, aluminum, zinc and coated parts, it will not cause corrosion discoloration or contact corrosion after use. The product contains unique antioxidant and acid-resistant components, which are not easy to oxidize and deteriorate after long-term storage, and can also maintain stability in high temperature and high humidity environments. This makes the BS-400 an ideal choice for unified anti-rust of multi-metal mixed wire bodies. There is no need to prepare multiple sets of oil products for different materials, and the management process is simplified.
Application scenarios: from workshop to warehouse, the whole process is safe
The Hank BS-400 series is suitable for a wide range of scenarios. In machine processing plants, it is used as an anti-rust agent between processes - after parts are removed from the machine tool, they can be cleaned or sprayed directly with BS-400 to keep them bright while waiting for the next process or assembly. In the auto parts and electronics industries, precision valve bodies, fuel injectors, bearing cages, etc. are soaked with BS-400 without residual sticky ash, and can be packaged and shipped directly without hindrance. In the field of hydraulic and pneumatic systems, its low viscosity characteristics allow it to be used as a running oil or debugging oil for equipment, providing rust protection while quickly draining moisture from the system and avoiding valve core stagnation. For long-term storage of mechanical parts, tooling fixtures, measuring tools and cutting tools, the long-term anti-rust ability of BS-400 can better help enterprises maintain inventory quality without frequent unpacking inspections.
In addition to excellent performance, the BS-400 series is also very environmentally friendly. The product does not contain harmful substances such as barium salts, chlorinated paraffin waxes, etc., and meets the requirements of RoHS and REACH regulations. Waste oil treatment is relatively easy. The low viscosity oil film can be easily removed with ordinary oil remover or alkaline cleaning solution before assembly, and will not bring additional burden to the subsequent surface treatment. This means that enterprises can actively respond to the green manufacturing trend and reduce the impact on the environment and operators while obtaining efficient protection.
