Industry & Occupation
Classification
Summary
Chemical manufacturing operator who processes cotton with mixed acids such as nitric acid and sulfuric acid to produce nitrocellulose (nitrocellulose).
Description
Nitrocellulose manufacturing workers process cotton fibers with a mixture of nitric and sulfuric acids to produce highly flammable nitrocellulose (nitrocellulose). The work spans multiple stages, including nitration reactions in reaction tanks, acid washing and neutralization, drying using centrifuges or continuous dryers, pulverization and sieving, and final quality inspection. Strict management of temperature, pH, and concentration is required at each process, along with equipment operation and maintenance inspections, and compliance with laws and safety regulations. Since it involves handling highly flammable and corrosive chemicals, the use of explosion-proof equipment and protective gear, as well as emergency response training, is essential.
Future Outlook
With the introduction of automated equipment and strict safety and environmental regulations, demand for workers with specialized skills remains stable. There is a slight decreasing trend due to the development of alternative materials for film applications, but niche markets for waterproofing, paints, and special uses will continue to require it.
