Functional pigments are a type of pigments with special properties and application fields. Different types of functional pigments can not only give objects color, but also achieve more functions. These pigments include fluorescent pigments, luminous pigments, high temperature resistant pigments, conductive pigments, etc., which play unique roles in various fields. This article will take an in-depth look at these functional pigments, revealing their properties and wide range of applications.
Luminous pigments: the charm of the night of light
Luminous pigments are rare earth energy-storage luminescent materials with excellent light absorption, light storage and luminescence capabilities. These pigments work by absorbing ultraviolet or visible light and storing the light energy in the crystal lattice. In dark places where light diminishes or disappears completely, luminous pigments can convert stored energy into light energy and glow, creating stunning effects. Luminous pigments can be used in marking, display, safety signs and other fields at night to provide a reliable light source.
Fluorescent pigments: a bright choice during the day
Fluorescent pigments are based on thermosetting resins and offer excellent tinting strength, fade resistance, extremely fine particle size and solvent resistance. When external light (including ultraviolet light) shines on fluorescent pigments, they can absorb specific forms of energy and do not convert it into heat energy. Instead, they excite photons and release the absorbed energy in the form of visible light, thereby producing fluorescent effects of different colors. During the day, fluorescent pigments are more vivid and eye-catching than other pigments and are widely used in signs, advertising, decoration and other fields.
Conductive Pigments: The Patron Saint of Antistatic
Conductive pigments usually use conductive carbon black as the main component and have an antistatic effect, which can prevent dust and charge accumulation on the surface of the coating. These pigments are suitable for applications where antistatic properties are required, such as electronic product assembly benches and computer room floors. In addition, metal powder pigments and antistatic agents such as gold, silver, and copper also have similar antistatic functions.
Anti-rust Pigments: Guardians of Steel
Anti-rust pigments are a special type of pigments, including red lead, zinc chrome yellow, etc. Zinc chrome yellow is one of the typical anti-rust pigments. The chromate ions in it can form a layer of metal oxide hydrate on the surface of steel, which has a passivation effect and effectively prevents rust and corrosion. Therefore, anti-rust pigments play an important role in protecting steel products. Among them, 109 zinc chrome yellow, 309 zinc chrome yellow, 509 zinc chrome yellow, etc. produced by Shanghai Chrome Yellow Pigment Factory have excellent properties.
High-temperature pigments: warriors that resist high temperatures
High-temperature pigments are usually made of inorganic oxides and have excellent high-temperature resistance, reaching temperatures above 800 degrees Celsius. These pigments have excellent weather resistance and are suitable for painting and marking in high temperature environments. Whether in aerospace, oil refining, high-temperature equipment coating or other high-temperature applications, high-temperature pigments play a key role.
In summary, functional pigments offer new possibilities for applications in various fields. They not only give the material rich colors, but also give it special functions, such as luminescence, conductivity, antistatic, anti-rust and high temperature resistance. The continuous research and development and application of these pigments will further promote the innovation and development of coatings, printing, signs, electronic products and other industries, bringing more convenience and beauty to our lives and work.
