CHLORATE-CANDLE FABRICATION BY HOT PRESSING

Abstract

An investigation showed distinct advantages to manufacturing chlorate candles by a hot-pressing technique, omitting water as a binder. Small quantities of water trapped in a chlorate candle can result in the production of significant quantities of chlorine. By the hot-pressing method, high-density candles (2.5 g/cc) were produced which yield the equivalent of 200 cu ft of oxygen (STP) from 490 cu in. of candle volume. Two methods can be used for forming candles: molding and extrusion. Molded candles are best formed at temperatures from 225 to 245 C at pressures from 10,000 to 5000 psi, respectively. A double-action ram can be used; with a single-action ram, successive pressing increments should be used to avoid uneven distribution of density. Use of a glass-wool blanket or oven annealing is recommended to avoid thermal stresses on cooling.
