Effective scale control and dispersion are essential to ensure that the pulping process always runs as efficiently as possible.
Among suppliers of pulp and paper chemicals, Mare stands out with its range of polyacrylates, which offer excellent scale and deposit inhibition properties.
Scale formation from pulping and bleaching liquor is a dynamic phenomenon that can be caused by temperature shock, pH changes, intense shear force and a supersaturation concentration of scaling ions. The most common scales are calcium carbonate, calcium oxalate, barium sulphate and calcium sulphate. Polyacrylate-based products act on threshold inhibition, chelation, stabilisation and the crystal habit modification of the scaling.
