Abstract:
A lime slaker system for converting quicklime to a lime slurry includes: a lime feeder; a base slaker that includes a slaking chamber and a dilution chamber; a grit remover; and a modular water panel with a piping assembly in fluid communication with at least the base slaker and grit remover. The modular water panel is configured to independently control water distributed to the slaking compartment, the dilution chamber, and the grit remover.
Abstract:
Process and apparatus is disclosed for providing a chemical reaction between calcium oxide containing grit particles to produce calcium hydroxide and heat, capturing the heat of hydration and using it to preheat water initially at ambient temperature, to rise to an elevated temperature to increase the amount of lime present in the water to a supersaturated lime suspension level, with the chemical reaction running to completion, followed by cooling. Heat from a water jacket may be used to raise the temperature in the lime slaker.

Abstract:
A rapid setting, controlled low strength composition of Class C fly ash is provided having a quantity of hydrated lime and an iron chelating compound in an amount sufficient to accelerate the hydration and set time of the fly ash. In some examples, a filler material is added. A method for acceleration of the hydration and set time of a cementitious mixture is provided wherein hydrated lime is added to the cementitious mixture in an amount in the range of 0.1% to 15% by weight and an iron chelating compound in an amount in the range of 0.01% to 5.0% by weight of the cementitious material. Further, a calcium source and an iron chelating compound may be added to a Class C fly ash to accelerate the hydration and set time of the ash.
Abstract:
The provided is a producing technology for an Mn alloy sputtering target having low contents of impurity components such as oxygen, carbon and nitrogen and controlled crystal conformation. The present invention is characterized by the production steps of: adding deoxidant comprising elements having stronger affinity for oxygen than that of Mn to Mn; subjecting the Mn to a deoxidization-melting treatment in a fire-resistant crucible to prepare low-oxygen Mn, in which Mn is melted until oxide of the added deoxidant floats in the Mn molten metal; mixing the low-oxygen Mn with constituent metals of a sputtering target by respective predetermined amounts; adding further the deoxidant to the mixture; vacuum melting the mixture; and subjecting the mixture to a casting treatment.
