Granted: 2005-03-29
Abstract: A press blanket for a pressing device intended for extracting water from a web in the press nip of a papermaking machine comprises an elastomeric matrix, in which the outer area, facing the web, is subjected to a thermal treatment in order to increase the wear-resistance. Although the elastomeric matrix thus consists of the same material throughout, the outer area, which is subjected to greater stresses, therefore exhibits increased wear-resistance. The press blanket is made in a single operation, by casting a hot-casting elastomeric matrix onto a cylindrical casting mold, while at the same time reinforcing threads are wound into the material. The press blanket is selectively thermally treated in order to achieve increased wear-resistance at the outer surface facing the web.

Abstract: The present invention provides corrosion inhibition formulations and compositions for inhibiting mineral scale and the corrosion of metals particularly the cavitation corrosion of aluminum in the presence of aqueous liquids. The combination of a mixture of polymeric polycarboxylates, azoles, nitrate salts, phosphates, stabilized silicates and transition metal compounds provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges. The addition of selected polymeric polycarboxylates not only significantly reduces glycol based coolant cavitation erosion-corrosion, heat rejecting aluminum corrosion, and hard water precipitates and scale, it has been discovered that polymeric polycarboxylates in combination with siloxane stabilized silicates enhance secondary silicate stabilization leading to improvement in aluminum corrosion protection and coolant life when utilized with selected amounts of the above-identified additives. The formulations are particularly suitable for automotive applications.
