What is corrosion protection? Basic knowledge of corrosion protection and introduction to corrosion protection tape [Materials]
This explains the mechanism of "corrosion prevention" that protects against corrosion caused by metal rust. Additionally, it introduces and explains "anti-corrosion tape," which is effective as a corrosion prevention material.
What is anti-corrosion tape? Anti-corrosion refers to the means of preventing corrosion. Since the methods of anti-corrosion vary depending on the causes and environment of the corrosion areas, it is necessary to assess the situation and use the appropriate method. Types of anti-corrosion <Metal Coatings> Plating, thermal spraying, vapor deposition, cladding <Non-metal Coatings> Paints (fluorine, acrylic, rubber chloride, polyurethane, MIO, lead oxide, etc.), anti-corrosion tape, rust preventive oil, resins (FRP, asphalt) <Corrosion-resistant Materials> Titanium, stainless steel <Electrical Anti-corrosion> <Environmental Treatment> Dehumidification, corrosion inhibitors (volatile rust preventives), pH adjustment Principle of Anti-corrosion The elements that cause rust are water (H2O) and oxygen (O2). When these combine with iron (Fe), red rust (Fe2O3) forms. To prevent rust formation, it is necessary to cut off the contact between the metal and water/oxygen. Anti-corrosion tape acts as a barrier to cut off this contact and has the ability to convert red rust into black rust. Red Rust and Black Rust Red rust generally refers to the common type of rust, while black rust is the oxide film that forms on the surface. Black rust has the property of converting red rust into black rust. Source: https://www.toishi.info/metal/akasabi_kurosabi.html
basic information
**Types of Anti-Corrosion Tape** **Petrolatum-based Anti-Corrosion Tape for Buried Pipelines "No.59 Series"** Also known as mastic tape or Denso tape, it is primarily used for underground buried pipes. (It can also be utilized for steel pipes and piles underwater, as well as underwater steel sheet piles.) It is made by impregnating a non-woven fabric with a compound primarily composed of petrolatum derived from petroleum, offering excellent flexibility and perfect adhesion to any shape. *For more details, please refer to the related catalog.* **Oxidative Polymerization Outdoor Anti-Corrosion Tape "Nitto Halumac XG Series"** This anti-corrosion tape, uniquely developed by Nitto Denko, can be used for all exposed areas outdoors. It is made by impregnating a plastic-based non-woven fabric with a compound primarily composed of specially formulated drying oil, which forms a film on the surface through oxidative polymerization, exhibiting excellent anti-corrosion and weather resistance. Additionally, due to its high flexibility, it adheres perfectly to any shape simply by applying and smoothing it out. It creates an excellent rust-proof and anti-corrosion layer with minimal effort. *For more details, please refer to the related catalog.*
