In the field of industrial manufacturing and metal processing, anti-rust treatment has always been an indispensable key link. Whether it is precision parts, molds, tools, or large machinery and equipment, once rust occurs, it not only affects the appearance, but also may lead to performance degradation, shortened life, and even lead to safety accidents. Traditional anti-rust oils often have pain points such as thick oil film, sticky hands that are difficult to clean, large dosage, high cost, and unstable anti-rust cycle. How to balance high-efficiency production with long-term protection has become a practical problem faced by many enterprises.
It is in this context that the Hank BS-400 series of anti-rust oils came into being. This series of products is designed with the core concept of "thin oil film, high protection". Through advanced oil-soluble corrosion inhibitor combination and special film-forming technology, a dense, uniform and extremely thin protective film is formed on the metal surface, achieving a protective effect beyond traditional oils with a very small amount. It is not only an upgrade of anti-rust technology, but also an innovation in industrial maintenance concepts.
Deciphering the protective code of the thin oil film
To understand the advantages of the "thin layer" of the Hank BS-400 series, it is first necessary to understand the mechanism of action of anti-rust oil. The root cause of metal rust is oxygen in the air, moisture, and electrochemical corrosion of corrosive media and metal surfaces. Anti-rust oil needs to form a barrier layer on the metal surface to cut off the contact between the corrosive medium and the metal. In order to ensure the protection effect, traditional anti-rust oils often rely on increasing the thickness of the oil film to "stack" the protection ability. However, too thick oil film can bring a series of problems: sticking dust, affecting the assembly accuracy, the workpiece is difficult to clean, the amount of oil used is huge, and the oil is easy to drip and pollute the environment.
The Hank BS-400 series revolutionizes this thinking. It uses a special polymer film-forming agent and composite corrosion inhibitor system. The molecules can be aligned in a directional manner on the metal surface to form a single-molecule or submicron-level protective layer with extremely high density. Although this oil film is extremely thin, it has strong hydrophobicity and salt spray resistance. From an electrochemical point of view, the corrosion inhibitor molecules effectively inhibit the anode and cathode reactions, greatly improving the polarization resistance. Therefore, the BS-400 series can provide several times the protective performance of traditional thick oil films in the state of extremely thin oil films, truly achieving "less wins more, and thin protects strength".
High protection, derived from scientific formula
The high protection of the Hank BS-400 series is not accidental, but based on a large number of experiments and precise formulation design. A variety of high-performance anti-rust additives are selected in the product, including sulfonates, carboxylic acids and special ester compounds. These ingredients work together to form a stable chemisorption film on the surface of steel, cast iron, copper, aluminum and other metals. Especially for harsh conditions such as salt spray environment, high humid and hot climate, and industrial acid gas pollution, the BS-400 series has undergone rigorous salt spray test and humid box test, showing excellent corrosion resistance.
In actual tests, the Hank BS-400 series can resist rust for carbon steel workpieces for more than 12 months under indoor storage conditions and more than 6 months in outdoor covered environments. For equipment exported by sea or long-term storage, the use of this series of anti-rust oils can significantly reduce the risk of rust. Its "high protection" is not only relative to its own traditional products, but also relative to the average level of similar thin-layer anti-rust oils in the industry. The BS-400 series achieves higher cost performance with lower film thickness requirements.
Fast penetration, affinity for metal surfaces
The Hank BS-400 series has excellent permeability and wettability. When the anti-rust oil is sprayed or dipped onto the metal surface, it can quickly flow and spread, penetrating deep into the tiny gaps, threads, and blind holes of the workpiece, ensuring that every subtle area is protected. This fast-penetrating feature greatly improves the construction efficiency, and is especially suitable for automated spraying lines and the treatment of large structural parts. The surface of the workpiece after construction dries quickly, forming a layer of non-stick, odor-free, and transparent protective film. Workers can easily handle the workpiece, and there is no need for cumbersome degreasing operations before subsequent processes. It can be quickly removed with ordinary degreasing agents or solvents.
What's more, this thin oil film will not affect the dimensional accuracy of the workpiece. For precision bearings, gears, measuring tools and other parts that require extremely high tolerances, the use of Hank BS-400 series can completely avoid the assembly error caused by thick oil film. At the same time, the transparency of the oil film is high, which is convenient for quality inspectors to visually inspect the condition of the metal surface and reduces the possibility of covering up workpiece defects due to the application of anti-rust oil.
A variety of models, suitable for different scenarios
The Hank BS-400 series is not a single product, but a highly targeted product family. According to different industries, different materials, and different anti-rust period requirements, the series is subdivided into a variety of specifications. For example, BS-401 is suitable for medium and short-term anti-rust of carbon steel and low-alloy steel, with thinner film and outstanding economy; BS-402 enhances salt spray resistance and is suitable for offshore equipment or marine exports; BS-403 is designed for special materials such as galvanized sheet and aluminum sheet, avoiding the risk of corrosion or white spots caused by certain anti-rust agents on non-ferrous metals.
This refined classification allows each customer to find the most suitable solution for their own process and cost requirements. Whether it is the transit rust prevention of shaft parts or the long-term storage of complete sets of equipment, the Hank BS-400 series can provide precise protection. At the same time, this series of products are all environmentally friendly solvents, and do not contain harmful substances such as hexavalent chromium, lead, and mercury restricted by the European and American RoHS directives, which meet the requirements of environmentally friendly and safe production. The workplace odor is mild, which effectively improves the operating environment and protects the health of front-line employees.
Use process and economic analysis
To give full play to the high protection advantages of the Hank BS-400 series, it is essential to standardize the use. Common construction methods include soaking, brushing, spraying and automatic spraying. No matter which method is used, the workpiece should be thoroughly cleaned and dried before rust prevention to remove sweat stains, cutting fluid, moisture and impurities on the surface. The recommended concentration can be adjusted according to the material of the workpiece and the requirements of the rust prevention period. For workpieces that require long-term rust prevention or harsh environment, the oil viscosity can be appropriately increased or a secondary dip coating process can be used.
In terms of economy, the use of Hank BS-400 series is usually only 30% to 50% of the traditional anti-rust oil. Taking the dip coating process as an example, the traditional anti-rust oil has a large amount of adhesion and high carry-out loss, while the BS-400 series has a significant reduction in fuel consumption per unit area due to the extremely thin oil film. Although its unit price may be slightly higher than that of ordinary anti-rust oil, the BS-400 series has obvious advantages in terms of protection cost per square meter, manual cleaning cost and waste liquid treatment cost. Especially in automated production lines, reducing oil splash and drip also reduces equipment maintenance costs.
In addition, the thin layer of oil film helps to simplify the subsequent packaging and storage process. The dry and non-stick surface can be directly bagged and boxed without sticking to the packaging materials. Even if the stock workpieces are stacked in multiple layers, they will not produce indentation or absorb dust due to the thick oil film. This undoubtedly improves the utilization rate of storage space and the quality of product delivery.
Real Applications: From Precision Manufacturing to Heavy Industry Equipment
The Hank BS-400 series has been widely validated in a number of industries. In the automotive parts manufacturing plant, differential gears are cleaned after processing, then dipped and coated with BS-401 and stored in a turnover box. After three months of inventory turnover, the surface of the gears is still as bright as new, and the cleaning step is eliminated before assembly. It is directly pressed and installed, which greatly improves the efficiency of the production line. In the construction machinery industry, after the inner wall of the hydraulic cylinder cylinder is sprayed with BS-402, it is exported to the high-humidity area of South East Asia. After two months of sea and port stops, the unpacking inspection does not find any rust points. In the hardware tool industry, after the drill bit, tap and other products are coated with the BS-400 series, not only the anti-rust effect is outstanding, but also the appearance is dry and beautiful, which improves the product grade.
These practical examples confirm that "thin layer oil film, high protection" is not a slogan. The Hank BS-400 series really makes rust prevention simpler, more economical and more reliable. In many established industrial enterprises, it was previously necessary to purchase a large amount of ordinary rust-proof oil every month. Due to the thick oil film attached to the workpiece, it was necessary to wipe it with gasoline or cleaning agent before assembly, which wasted man-hours and generated a lot of hazardous waste. After switching to the Hank BS-400 series, some workpieces can be assembled directly without cleaning, because the remaining thin oil film has no negative impact on assembly and lubrication. This change saves the company a lot of cost every year.
Environmental protection and safety: pioneers in green rust prevention
In today's increasingly stringent environmental regulations, the safety and environmental protection attributes of industrial oils have received unprecedented attention. Hank BS-400 series strictly follows the principles of green chemistry in the product design stage. The base oil used is highly refined mineral oil or synthetic hydrocarbons, with extremely low aromatic hydrocarbon content and far lower volatile organic compound emissions than traditional solvent-based anti-rust oils. The flash point is high, which makes it safer during storage, transportation and use, reducing the risk of fire. At the same time, the product does not contain chlorine and nitrite, and will not leave harmful substances on the metal surface. Waste oil and packaging containers can be disposed of according to general industrial waste oil, effectively reducing the environmental pressure of enterprises.
It is worth mentioning that the BS-400 series oil film also shows good compatibility in contact with packaging materials. It will not swell or crack with certain plastic and rubber seals. For workpieces with rubber seals, the use of the BS-400 series can avoid the failure problem caused by oil corrosion of rubber. This is essential in rust prevention of many complex components.
