摘要
A method for producing zinc diammine chloride (ZDC) from a solution of zinc ammine sulfate and zinc ammine chloride by precipitating the ZDC by pH neutralization using hydrochloric acid. ZDC can be granulated for dry applications using melt granulation at about 171-182° C (340-360° F). Applications for ZDC include use in fertilizer formulation to provide a combination zinc/nitrogen source free of other metals and use as a galvanizing preflux adjuster. As a galvinizing preflux adjuster, ZDC addition is able to adjust the pH of the preflux while maintaining the desired zinc/ammonia ratio.
