Metal structure anti-corrosion product

Anti Rust Coating For Metal is a technology that prevents the metal surface from contacting with corrosive media (such as water, oxygen, salt spray, etc.) through physical isolation or chemical passivation, thereby delaying or preventing rust. It is widely used in mechanical processing, automobile manufacturing, shipbuilding, energy and other fields, and is a key means to improve the durability of metal parts. Product Details: - Relying on years of accumulation of precision CNC machining technology, Hansheng Automation focuses on the corrosion protection needs of metal parts and launches high-protection, high-precision and compatible metal anti-rust coating solutions. Through zinc-aluminum composite coating and sealant technology, it can achieve 2000 hours of neutral salt spray protection (ASTM B117 standard), acid and alkali resistance (pH 3-11), and UV aging resistance. It can withstand the complex corrosion environments in machinery, automobiles, electricity, and tobacco packaging machines. It does not affect the assembly accuracy of precision parts such as bearings and cam dividers. "CNC machining + anti-rust coating" integrated services are also provided to extend the service life of metal parts and ensure the stability of working conditions. Core advantages: - ✅ Ultra Guard: Adopting zinc aluminum composite coating and sealing agent technology, it has passed the 2000 hour neutral salt spray test (ASTM B117), far exceeding the industry standard. - Acid and alkali resistant (pH 3-11), UV aging resistant, suitable for extreme environments such as offshore platforms and chemical equipment. - ✅ Precision compatibility: The coating thickness is only 8-15 μm, which does not affect high-precision fitting (H7/h6 tolerance) and avoids rework in post-processing. - Low hydrogen embrittlement characteristics, compliant with ISO 9587 standard, suitable for key components such as high-strength fasteners and bearings. - ✅ Efficient process: Supports multiple processes such as electrophoresis, spray coating, and dip coating, and is suitable for complex structural components such as internal cavities and threads. - Low temperature curing at 80°C reduces energy consumption by 40% compared to traditional hot-dip galvanizing. - ✅ Environmental compliance: Cr6+Free, lead-free, compliant with RoHS/REACH directives, worry free export to the European Union. Typical application scenarios: - Automotive components: brake discs, transmission shafts rust proof, extend service life by 30%+ - Precision mold: prevents corrosion by cooling water and maintains surface smoothness (Ra ≤ 0.8 μm) - Power facilities: Substation connectors, capable of withstanding high salt spray environments along the coast Comparison of Technical Parameters: - Indicator: Traditional galvanized - Salt spray tolerance (h): 500 - Coating thickness (μm): 20-30 - Adhesion (grid cut method): Level 2 - Indicator: XX nano coating - Salt spray tolerance (h): 2000+ - Coating thickness (μm): 8-15 - Adhesion (grid cut method): Level 0 FAQ: - Q: Is your metal anti-rust coating compatible with all metal materials? For example, common materials like stainless steel, aluminum alloy, and carbon steel? A: It's compatible with most common metal materials. Carbon steel/cast iron: A phosphating treatment is performed first to enhance the coating's adhesion and prevent oxidation of the substrate. Stainless steel (304/316L): Sandblasting is used to activate the surface to address the problem of weak coating adhesion caused by the stainless steel's surface inertness. Aluminum alloy: A chromating (environmentally friendly) pre-treatment is performed first to prevent chemical reactions between the coating and the aluminum substrate and improve salt spray resistance. Only for some special materials (such as pure titanium and Hastelloy alloy) does prior consultation require a customized coating solution. - Q: If a metal part undergoes secondary processing such as drilling or tapping after anti-rust coating, will this compromise the coating's protective effect? A: Localized processing will damage the coating in the corresponding area, but overall protection can be maintained through post-processing recoating: For small-area processing (such as single-hole drilling): After processing, manually reapply a special repair compound (with the same composition as the original coating) to a thickness of 8-15μm. Curing is required at 80°C for 2 hours. For large-area processing (such as multi-thread tapping): "Local protection" can be applied first—the processed area is temporarily uncoated. After the secondary processing is completed, reapply the entire coating to ensure no blind spots. - Q: We need to apply an anti-rust coating to the carbon steel frame of a tobacco packaging machine. The frame has weld scars on the surface. Do we need to treat the scars before applying the coating? Will not treating them affect the protective effect? A: Weld scars must be treated first; otherwise, the coating's protective effectiveness will be severely affected. Specific treatment requirements are as follows: Scar Treatment Standards: Use an angle grinder to grind weld scars flush with the substrate surface, avoiding sharp protrusions or indentations. Hazards of Not Treating: Weld scars can easily retain weld slag and scale, preventing the coating from adhering properly. In salt spray environments, rust will initially form at the scars, rendering the overall protective effect ineffective. Our Services: We offer an integrated "pretreatment + coating" service, integrating weld scar treatment into the pre-process, meeting the long-term rust prevention needs of the humid environment of tobacco workshops.
