Description
Over 90% of the demand for diamond wire is in the photovoltaic sector, where it is used for silicon ingot cropping, blooming of silicon ingots, and wafer slicing. The weight of diamond wire is approximately 0.0406 g per meter. This dataset includes major raw and auxiliary materials, energy use, atmospheric emissions, and waste from the production process and environmental protection procedures. Infrastructure such as manufacturing of production equipment and construction of facilities are not included within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. Diamond wire production involves processes including alkaline oil removal, water rinsing, pre-plating, sand coating, nickel thickening, water rinsing, electric drying, and winding.
Activity Description
