Description

(54) .COMPOSITION FOR MAKING HYDRATE LIME

one

The invention relates to the technology of living materials and can be used in the production of hydrated lime. ; A known composition for the manufacture of hydrated lime, including lime-Boil, and an additive, such as sulfite alcohol bard.

However, the known mixture characterizes, with a high slaking rate and reduced strength of products made from such lime.

The aim of the invention is to slow down the rate of slaking and improve the quality of lime.

For this, lime as an additive contains fodder yeast in the following ratio of components, wt. %:

99.0 - 99.8

Lime Oh, 1, O Feed Yeast

The addition of fodder yeast significantly slows down the process of slaking lime and reduces the temperature of the mixture. If the rate of quenching, as determined by the standard method, without an additive is 30 min.

then with the addition of 0.2% fodder yeast 6O min, with the addition of 0.7% yeast - 1OO min. The temperature of the mixture, with the introduction of the specified quenching rate retarder, decreases by a factor of 2 to 4 compared to additive-free lime. The strength of lime-silicate products on lime with the addition of fodder yeast than with the addition of sulfite-alcohol stillage.

Feed yeast consists of 45.6%

from protein and 35.2% nitrogen-free extractives. In addition, they contain 1.5% fat, O, 2% fiber, 7.8% ash and 9.7% water.

The additive is introduced into the water of the gate,

while reducing the volume of the water of the gate.
