Carbon Black (Micronised)

Micronized Carbon Black, also known as powdered carbon black, is a fine particle form of carbon black. It is produced by milling or grinding larger carbon black particles into a smaller size range, typically below 1 micron. Micronized carbon black finds various applications in the construction industry due to its unique properties.

Here are some common uses and applications of micronized carbon black in construction:

Concrete and Cement: Micronized carbon black can be used as an additive in concrete and cement formulations. It enhances the mechanical properties of concrete, such as compressive strength, durability, and resistance to chemicals and abrasion. It also improves the workability and reduces the bleeding and segregation of concrete mixes.

Asphalt and Bitumen Modification: Micronized carbon black is added to asphalt and bitumen mixtures to enhance their performance. It improves the asphalt’s resistance to UV radiation, aging, and thermal cracking. It also increases the stiffness and viscosity of bitumen, leading to improved rutting resistance and reduced deformation in road pavements.

Coatings and Paints: Micronized carbon black is used as a pigment in coatings and paints for the construction industry. It provides excellent black coloration and UV resistance to protect the underlying surfaces from fading and degradation. It also improves the conductivity and antistatic properties of coatings, making them suitable for specialized applications.

Thermal Insulation: Micronized carbon black can be incorporated into thermal insulation materials to enhance their thermal conductivity. It helps to reduce heat transfer and improve the energy efficiency of buildings. Additionally, it contributes to the mechanical strength and fire resistance of insulation materials.

Waterproofing Systems: Micronized carbon black is used in waterproofing systems, such as liquid membranes and coatings. It enhances the UV stability and durability of these systems, preventing water penetration and protecting structures from moisture damage.

Electrical Conductivity: Micronized carbon black can be added to construction materials to impart electrical conductivity. It is used in antistatic flooring, concrete for grounding purposes, and conductive adhesives for electrical connections.

Anti-corrosion Coatings: Micronized carbon black is incorporated into anti-corrosion coatings for metal structures. It acts as a barrier against moisture and corrosive elements, extending the lifespan of the coated surfaces.

Overall, micronized carbon black is a versatile additive that improves the performance and durability of various construction materials. Its applications range from enhancing the strength and longevity of concrete to providing coloration, UV resistance, and conductivity in coatings and paints.
