【Abstract】 On the basis of analyzing the composition of the piped solution and the pipe scaling in a lead-zinc mill,an approach to causes of pipe scaling was made. By making the tests in the laboratory,a kind of functional scaling-depressed coating,which used polyurethane resin as film forming material and the scaling-depressed additive as additional composition,was developed and tested on the technical scale in this mill,with a good scaling-depressed result.更多还原
