一、干燥时的操作过程炸药的干燥工作是在一间‘温度45度±5度’夹墙干燥室内(如第一图)进行的。首先将药粉,散铺在干燥架上(如第二图),(每层厚约五公分,过一小时翻一次,四小时后,将药装入玻璃瓶中密闭,然后将玻璃瓶移放在常温室内冷却,四小时后,再进行第二步磨碎过篩工作。二、磨碎过篩的操作过程磨碎工作是在一架有边缘垫、有玻璃砖的木架上(如第三图)进行的。先用木滚筒将固结的炸药压碎,(每次所压数量不超过五公斤)然后使用200个網目左右篩子过篩(我们是采用油印机上的纱布做的篩子过篩的),并将篩好的药粉放入玻璃干燥器内,(以减少药粉与空气接触时间)然后再进行第二次磨碎过篩工作。
First, the operation of the drying process Explosives drying work in a ’temperature of 45 degrees ± 5 degrees’ wall drying room (Figure 1) carried out. First of all, the powder, scattered shop in the drying rack (Figure 2), (each layer is about five centimeters thick, turn over an hour later, four hours later, the medicine into the glass bottle closed, and then the glass bottle Cooling in the room at room temperature, four hours later, and then the second step of grinding and screening work. Second, the process of grinding and sifting The grinding work is in a framed edge with glass tiles on the wooden frame (such as the third Figure) The first wood roller will be consolidated explosives crushed (each press the number of not more than five kilograms) and then use the 200 mesh sieve sieve (we are using gauze on the screen printing machine made of sieve ), And the sieved powder into the glass desiccant, (to reduce the powder contact with air time) and then the second grinding screening work.
