Powder Coating Application Process and Requirements
News 2025-09-25 471
1. Electrostatic Powder Coating Principle Electrostatic powder coating operates on the principle of a high-voltage electrostatic corona field. The metal guide ring at the gun tip is connected to the negative high-voltage terminal, while the workpiece to be coated is grounded, serving as the positive electrode. This setup creates a strong electrostatic field between the gun and the workpiece. Compressed air, acting as the carrier gas, transports t
An Overview of Resin Types and Key Varieties in Powder Coatings
News 2025-09-25 382
While the range of powder coatings is not as extensive as that of solvent-borne coatings, a considerable number of polymer resins can serve as their film-forming substances. These are broadly classified into two main categories: thermosetting and thermoplastic. 1. Thermosetting Powder Coatings: The High-Performance Mainstream Thermosetting powder coatings use thermosetting resins as the film-forming material. When heated with a cross-linking age
Transformer Corrosion Protection: From Traditional Grease to Vapor-Phase Rust Prevention
News 2025-09-19 358
1. Rust, the Invisible Killer of Transformers Many people may underestimate the detrimental effects of rust on transformers. Once rust develops in core components such as the core and windings, it not only reduces energy efficiency and increases losses, but can also cause localized overheating due to abnormal heat dissipation, leading to accidents. Rust on structural parts and fasteners is equally problematic, complicating inspection and disassem
The Role of Parts Cleaners in Metal Processing
News 2025-09-19 396
Parts cleaning is an essential process in machining and metal product production. Whether it’s cutting, stamping, tapping, or even applying rust-proof oil during long-term storage, various oil stains and oxides remain on the workpiece surface. Failure to promptly remove these stains not only affects subsequent machining accuracy and assembly quality, but can also lead to surface rust and reduced adhesion. Therefore, an efficient and reliabl
The main properties of fluororubber
News 2025-09-19 467
1. Brief Overview Fluororubber refers to a polymer elastomer containing fluorine atoms on carbon atoms in the main chain or side chains, resulting in exceptional properties. The material discussed here is Fluoro-26 or Fluoro-246 (also known as Viton-type fluororubber), which are binary and ternary copolymers of vinylidene fluoride and hexafluoropropylene (the third monomer is tetrafluoroethylene). Fluororubber accounts for over 90% of global fluo
Design and processability study of perfluoroether rubber
News 2025-09-19 385
Perfluoroether rubber (FFKM) is composed of a tetrafluoroethylene (PTFE) main chain and perfluoromethyl vinyl ether (PMVE) side chains and bridging parts. It not only has excellent properties of high temperature resistance and chemical corrosion resistance (resistant to more than 1.600 chemicals), but also has the elasticity of rubber. FFKM products are mainly used in aviation, aerospace, petroleum, chemical industry and atomic energy industries
Powder Coating Problems and Solutions
News 2025-09-18 504
Introduction Powder coating problems, such as the inability to effectively coat the workpiece surface or excessively thin coatings, are common challenges in the powder coating industry.The application of powder coatings involves multiple stages, including formulation design, spray equipment, process parameters, workpiece pretreatment, and environmental conditions. Even minor variations in these factors can affect the final coating quality. Theref

In the core area of the petrochemical industry, harsh working conditions of high temperature, strong corrosion and large pressure difference are everywhere. From the hot furnace tubes of the cracking furnace, to the high pressure environment of the hydrogenation reactor, to various strong acid and alkali transmission pipelines, the safe sealing of the equipment bears the heavy responsibility of the entire process. A tiny leak can cause the los
Structural characteristics and application fields of fluororubber
News 2025-06-26 454
Structural characteristics: Because there is no unsaturated C=C bond structure on the main chain of polyolefin fluororubber (26-type fluororubber, 23-type fluororubber) and nitroso fluororubber, the possibility of degradation and chain breakage on the main chain due to oxidation and pyrolysis is reduced. The methylene group in vinylidene fluoride plays a very important role in the softness of the polymer chain. For example, fluororubber 23-21 an
Precautions for using anti-rust film
News 2025-06-26 477
Anti-rust film is a plastic film. It is an anti-rust film made by adding certain chemical element masterbatch. It can directly contact the metal surface and protect the metal from rust through a relatively closed space in the environment. Analysis of anti-rust film types Generally speaking, anti-rust films can be divided into the following types: ordinary anti-rust film, anti-rust embossed film, anti-rust bubble film, etc. Different metals requi
