Anticorrosive Pigment formulation of low Environmental Impact based on Calcium acid phosphate. Procedure for obtaining Calcium acid phosphate, active Pigment formulation

摘要

It is an anticorrosive Pigment formulation of low Environmental Impact based on Calcium acid phosphate.Used as a Pigment and Chalk Active zinc oxide; pH Regulators as Pigments and Titanium dioxide as pigmentocubr purposes.The formulation of Environmental bajoimpacto proposal anticorrosive Pigment composition is characterized by the following: 191% of Calcium acid phosphate (Pigment Active Corrosion Inhibitor), 10.8% (2 decalcio Chalk CARBONATE), 2.4% 12.6% zinc oxide and Titanium dioxide.We describe the composition of a revestimientoanticorrosivo characterized by the above formulation contain Pigment and a Binder consisting of unaresina type lquid PureWith uncontenido Solids from 49 - 51% and Oil content, Resin, 52%.The Procedure of preparation of Calcium acid phosphate, active anticorrosive Pigment formulation, involves a process of precipitation from a quantity q of Phosphoric acid.Obtained from laexpresion 5693 / p = R (R = Wealth of Phosphoric acid and Calcium Hydroxide a Number C such that c = 4300 / R (R = Wealth decalcioempleado Hydroxide).The Components are mixed in the following way: The Acid is diluted with 10 times volume of water and hydroxide is added decalcio with Continuous Shaking for two hours.The precipitate obtained was filtered, washed, dried and sifted through a Sieve. Deemplearlo 175 before the Pigment formulation.
