Abstract
The procedures for preparing zinc powder without mercury includes following steps. With certain proportion of aluminium, bismuth and indium being added into, the evenly mixed melted zinc metal liquid is cooled and cast in ingot after the impurities in the liquid being removed. By using special milling machine to cut the prepared ingot and high-speed eddy mill to smash the cut crumbs of zinc, the zinc powder without mercury is obtained with powder size of 10-325 screen mesh. The invented zinc powder is widely utilized in manufacturing primary and secondary alkali manganese cell as well as special cells.
Description
The present invention relates to the metal production, is preparation method of a kind of mercury less zinc powder and products thereof.
The development of battery industry is more and more higher to the requirement of zinc powder, and with traditional distillation and the prepared zinc powder of atomization, every technical indicator can not reach requirement, and has defectives such as production cost height, contaminate environment, can not satisfy industry requirement fully.
The purpose of this invention is to provide that a kind of complete processing is simple, the preparation method of the mercury less zinc powder of low production cost, excellent quality and products thereof, to improve function and the quality that once reaches the secondary alkaline Mn cell.
The preparation method of a kind of mercury less zinc powder of the present invention comprises dissolves zinc, add aluminium, bismuth, indium by a certain percentage, to dissolving fully and evenly, precipitating and remove impurity, be cast into ingot after the cooling, no mercury zinc ingot metal with method for preparing, on production miller, cut into no mercury zinc bits, the no mercury zinc crumb high-speed eddy pulverizer of preparation is pulverized, can obtain 10-325 purpose mercury less zinc powder, be a kind of physical preparation method that uses mechanical workout, can effectively prevent the oxidation of zinc.
Temperature during described adding aluminium is at 600-650 ℃.
The parts by weight proportioning of described no each composition of mercury zinc is:
99.87 parts of aluminium 0.004-0.009 of zinc part
Bismuth 0.04-0.06 part indium 0.04-0.06 part
Impurity＜0.0049 part
Further describe the present invention below in conjunction with embodiment.
Embodiment
The preparation method of a kind of mercury less zinc powder of the present invention, zinc is dissolved, add aluminium, bismuth, indium by a certain percentage, to dissolving fully and evenly, precipitating and remove impurity, be cast into ingot after the cooling, no mercury zinc ingot metal with method for preparing, on production miller, cut into no mercury zinc bits, the no mercury zinc crumb high-speed eddy pulverizer that makes is pulverized, can obtain 10-325 purpose mercury less zinc powder.
