Considering that it is easier to grind CS into a powder than GBFS, this study controlled the particle size of CS and ensured it was finer than that of GBFS, which can reduce the energy consumption of grinding. However, the different roles of the CS and GBFS in the hydration process lead to the formation of cementitious materials being complicated.
During the manufacturing process of PCB boards, the substrate needs to be copper-immersed, copper-coated and copper-ground, and in the process of copper-ground boards, the conventional equipment will discharge the wastewater generated from the grinding of boards (which contains a large amount of copper powder) directly into the sewage tank, and will …
