Abstract:

This report is concerned with the colloiding step by which nitrocellulose is prepared for extrusion into powder grains. The powder grains of wood cellulose origin have a somewhat more brittle nature than in the case of cotton products. Polarized light and X-ray examination reveal that the powder grains as now produced are for the most part heterogeneous in composition. When the green powder is freed of solvent the total shrinkage is related to total solvent used in the colloiding, while the resulting distortion of shape is related to the manner in which the solvent leaves the grains. No serious evidence has been found that shows that low viscosity nitrated products are wholly unsuitable for use.
