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)

jilypad raising baby harry but still having sirius be his godfather - cause harry is obvi still biologically jilys - and it might confuse a toddler to teach him he has three parents whilst he’s only just learning about mummies and daddies at kindy. but one night he has a bad dream or something and goes to find his daddy for help because he’s the best at nightmares (he’s had so much practice with sirius at hogwarts) and he sees james and sirius kissing and then also sees sirius and lily kissing sometimes because harry’s so sneaky with quiet little footsteps right. and so harry thinks it’s very normal to kiss your friends and that’s how you show that you’re best friends because lily and james always refer to sirius as their best friend.

and so harry goes to school and gives draco a kiss on the playground one afternoon because they’re best friends amd that’s what best friends do and little draco who never sees his parents kiss - who reads books about kisses being a very magical special thing - goes bright red and spends the rest of his kindergarten year thinking him and harry are boyfriends and brings him flowers and things and this litteraly goes on for years until they’re like 12. because they’re kids - a little pec is as crazy as it gets and harry still thinks it’s normal for besties to do that and draco is so in love with his silly boyfriend.

and then one day james sirius and lily sit harry down and decide it’s time to explain polyamory and talk about their real big feelings.

and then harry just freaks out.

they think he’s freaking out because he’s been taught by other kids at school that queerness is bad or whatever but then harry’s just like “so… is it not normal to kiss your best friend? is it not normal to hold their hands when you’re walking down the street and get them flowers. you only do that because you’re all in love?”

and now they’re all freaking out because they don’t know if harry has a boyfriend or not and all the boys are too chicken to ring up and ask because that’s so embarrassing for harry and lily is just sitting there with her head in her hands wondering how the hell her son ended up just as stupid as her dads.

one call to narcissa from her, and she figures it out, “oh, lily! hi, i was going to call later and ask you all over to dinner next week for draco and harry’s anniversary, he just came out to us.”

once again, lilys the one who has to do the communicating for these loveable idiots.
