2.The strength character of lean concrete road base material influenced by age and the amount of fly-ash used in it was studied through test in the lab.
3.Using lean manganous carbonate ore as a raw material in suspension bath process to improve performance of solid phase surface,and using efficient additive to eliminate harmful metals such as Mo,Fe2EMD for mercury -free alkaline Zn/MnO2 batteries was produced.
4.In addition to the methods,some proposals such as the sour gas temperature entering the absorber,the temperature detection in the absorber,the lean solution circulation boosting by pumps in series and the material of the stripping still shell are made.
6.Identify, implement and track performance to material cost saving initiatives through developing cost reduction, supplier rationalization, and optimum lean strategies for assigned commodities and executing strategies accordingly.
