Abstract
Inventia se refera la un lubrifiant pentru matritare la cald, constituit dintr-un amestec între: 4...6% în greutate ulei mineral emulsionabil, 6...8% în greutate ulei mineral neemulsionabil, 20...25% în greutate carboximetilceluloza, solutie apoasa 25%, 50...60% în greutate slam anorganic de hidroxid de fier, crom, nichel, rezultat la reducerea Cr VI si a celorlalte metale grele din solutiile epuizate de la galvanizare, cu sulfat feros si pîna la 1% în greutate grafit coloidal.The invention relates to a hot-melt lubricant consisting of a mixture of: 4-6% by weight emulsifiable mineral oil, 6-8% by weight of non-emulsifiable mineral oil, 20-25% by weight 25% aqueous solution, 50-60% by weight of inorganic iron oxide, chromium, nickel, resulting in the reduction of Cr VI and other heavy metals from the ferrous sulphate exhausted solutions and up to 1 % by weight of colloidal graphite.
