The demand for diamond wire in the photovoltaic field exceeds 90%, and it can be for silicon ingot cutoff, silicon block squaring, and silicon wafer cutting, with the weight of diamond wire being about 0.0406g per meter; this dataset includes primary raw and auxiliary materials, energy usage, atmospheric emissions, and waste from the production process and environmental protection procedures. The dataset boundary does not include infrastructure such as production equipment manufacturing and plant construction; the data inventory is formed by merging data from multiple sources; the production of diamond wire includes procedures like alkaline degreasing, washing, pre-plating, sanding, thickening nickel, washing again, electric drying, and rewinding.
