USE OF ULTRA-FINE SODIUM BICARBONATE POWDER FOR PREPARATION OF FOAMING AGENT |
摘要 |
<p>Ultra-fine sodium bicarbonate powder (mean particle size less than 5 microns) is produced by the mixing and reaction under agitation at control temperatures of solutions of ammonium bicarbonate and sodium chloride. Precipitated sodium bicarbonate is separated by filtration as a slurry which is dried to produce ultra-fine sodium bicarbonate. Ultra-fine sodium bicarbonate produced by this method also exhibits a narrow particle size distribution which is advantageous in blowing agents for thermoplastic resins, to produce a foamed resin with small cells of a narrow size distribution.</p> |
