CELLULOSE / PULP
Nitrocellulose
Nitrocellulose (cellulose nitrate) is a well-established yet highly relevant material to this day. Through controlled nitration of cellulose, a versatile raw material is produced that – depending on its nitrogen content – plays an essential role in a wide range of industries:
- Coatings and varnishes: Nitrocellulose-based lacquers ensure fast drying, brilliant surfaces and excellent resistance, e.g. for furniture or automotive components.
- Printing inks: Nitrocellulose serves as a binder for high-quality flexographic and gravure inks on packaging and films.
- Cosmetics: Used in nail polish to create an elastic, glossy film.
- Medical & laboratory: Nitrocellulose membranes are essential in filters and test strips.
- Pyrotechnics & propellants: Guncotton (high nitrogen content) is a key ingredient for smokeless powders.
Customized machinery for nitrocellulose production
NETZSCH provides powerful solutions for processing nitrocellulose. Our machines help you to safely and efficiently grind and homogenize this demanding material
NETZSCH CHM Hammer Mill – Ideal for gentle pre-grinding and processing of nitrocellulose.
In the production of nitrocellulose (NC), the raw cellulose must be in fibrous form prior to further chemical treatment. The raw material is prepared accordingly using CHM Hammer Mills. Before entering the hammer mill, the cellulose, in the form of web goods, is continuously fed via a specially designed conveyor into a rotary beater, where it is separated into fibers with no bundling or knotting.
Thanks to robust design and adaptable rotor geometries, NETZSCH Hammer Mills offer flexible solutions for various throughput and fineness requirements.
NETZSCH Tooth Disc Mill Horizon – ideal for nitrocellulose
The NETZSCH Tooth Disc Mill Horizon is perfectly suited for the gentle yet efficient processing of nitrocellulose. With an adjustable grinding gap and flexible disc options (tooth, pin or defibrator discs), it is specially designed for temperature-sensitive, fibrous products. Its robust construction enables safe continuous operation and ensures consistent product quality – with minimal heat generation and low fine fraction.
The TDM Horizon ensures intensive, uniform homogenization and dispersion and guarantees optimal product quality and process safety in further processing of nitrocellulose
