Hace 2 días · This process breaks down the lignin in the wood, separating fibres and turning them into mash. This is known as the kraft pulping process. A benefit of kraft pulping is that roughly 90% of the pulping chemicals can be recovered and reused economically. Paper Formation: Next, the mash is washed, screened, and refined to create a slurry.
Hace 1 día · CNCs were produced from bleached Kraft pulp by sulfuric acid hydrolysis. According to CelluForce specifications, CNCs present dimensions of 2.3–4.5 nm in cross-section and 44–108 nm in length (as measured by Atomic Force Microscopy, AFM); a crystalline fraction of 0.88 (measured by X-ray diffraction); and a surface charge density of 0.023 mmol g −1 (measured by conductometric titration).
Hace 5 días · Bleached Chemo Thermo Mechanical Pulp (BCTMP) is a type of pulp produced by treating wood chips with chemicals and heat. It is then bleached to remove impurities and enhance brightness....
