Organobentonite Binder for Binding Sand Grains in Foundry Moulding Sands. [PDF]
Materials (Basel), 2023 A series of studies related to the production of organobentonite, i.e., bentonite-poly(acrylic acid), and its use as a matrix grain-binding material in casting moulding sand is presented. In addition, a new carbon additive in the form of shungite was introduced into the composition of the moulding sand. Selected technological and strength properties of
