How is carbon black measured?

Carbon black is a versatile material used in a variety of industries, including rubber, plastics, coatings, inks, and more. To ensure its quality and suitability for specific applications, carbon black is measured using various parameters and techniques. In this article, we will take an in-depth look at the different methods used for carbon black measurement and provide a comprehensive guide to understanding this important aspect of carbon black analysis.

Particle size distribution:

One of the key measurements of carbon black is its particle size distribution. Particle size affects the performance and behavior of materials in different applications. There are various techniques for measuring particle size, such as laser diffraction, sedimentation, and microscopy. Laser diffraction is a popular method that uses scattered light to determine size distribution, while sedimentation involves measuring the sedimentation rate of particles. Microscopy allows detailed examination at the level of individual particles.

Specific surface area:

The surface area of carbon black significantly affects its properties, such as its ability to adsorb species, interact with other materials, and provide reinforcement. Traditionally, the BET (Brunauer-Emmett-Teller) method is used to measure specific surface area. The technique involves the adsorption of gas molecules onto the surface of carbon black and determining the amount of gas adsorbed. The higher the specific surface area, the more effective the carbon black is in many applications.

Structural and surface chemistry:

The structure and surface chemistry of carbon black play a crucial role in determining its performance. Morphological characteristics, such as aggregate size, shape and porosity, affect the dispersion and reinforcing capabilities of carbon black. Techniques such as transmission electron microscopy (TEM) and scanning electron microscopy (SEM) provide valuable insights into the structure and morphology of carbon black particles. Surface chemistry can be analyzed by techniques such as X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR), which help identify the functional groups and surface features of carbon black.

Tint Strength and Chroma:

Tinting strength refers to the ability of carbon black to impart color or hue to a material. It is an important parameter for the ink, plastics and coatings industries. Tinting intensity can be measured by comparing the color intensity of a sample mixed with a standard reference material. Colorimetry is a precise method that uses color parameters such as Lab* values or CIE (International Commission on Illumination) color space coordinates to quantify the color properties of carbon black. These measurements are critical to maintaining consistency and meeting color specifications for various applications.

Rheological properties:

The rheological properties of carbon black, such as viscosity and flow behavior, are critical to its processing properties in the rubber and polymer industries. The Mooney viscosity test is commonly used to measure the viscosity of rubber compounds filled with carbon black. In addition, dynamic mechanical analysis (DMA) and rotational viscometry help determine the effect of carbon black on the viscoelastic behavior of the material.

Accurate measurement and characterization of carbon black is critical to ensuring its quality, performance and suitability for specific applications. Particle size distribution, specific surface area, structure and surface chemistry, tinting strength and rheological properties are key parameters used to measure and analyze carbon black. These measurements enable manufacturers and end users to select the appropriate carbon black grade based on their desired results.

remember when chat blanc aired and chat noir almost cataclysming his dad was a big deal. like all the fans were shocked and some were even upset at him for even considering/bluffing to do something so awful to someone, even though he didn't go through with it

anyway. remember when bug noire straight up just cataclysms her boyfriend's dad for real, no hesitation, no bluffing, with a big smile on her face

AND EVERYONE CLAPPED (INCLUDING ME) (GOOD FOR HER) (I SUPPORT WOMEN'S WRONGS) (HE DESERVED IT) (WISH HE DIDNT HAVE THE OX) (DO IT AGAIN)

my hot take: i think they should institute a minimum paint usage so they stop de-cuntifying the cars to reduce weight

it's quite random but are we gonna call 2025 Williams duo as carbon?

As a lifelong Taylor Swift & The 1975 stan, this album was …a lot to digest 🫠 My initial thought of “I should print out the lyrics so I can learn the songs faster” turned into a bigger project than I intended but I’m OBSESSED with the outcome 🤩

Typeset was made by me ☀️

Lyrics and content obviously made by Taylor Swift ✨

The patches in the front cover pocket were designed by @reputayswift 💕

This was taken during "Nazareth", one of my favorite Sleep Token songs, so I made this drawing just because. :)
