SU590284A1 - Composition for manufacturing gas-cypsum - Google Patents

Description

The invention is lacking in the building materials industry and can find the use of irn for the manufacture of gas-coated teilo-insol cnon and sound-absorbing products.

Known for komiosiii for the manufacture of gas and gas, including semi-aquatic giis, incremental additives and water 1.

Also known is a composition for the manufacture of a gas-hypogea, including semi-water gypsum, limestone and alkaline actinvizator 2.

This composition is closest to the invention of the technical essence and the achieved result.

A 1-1 doe-ket () to a known cosmological formula consists in their higher volume.

The reduction in volumetric mass of the gas turbine for the manufacture of gas gypsum, including semi-aquatic guinea, aluminum frond, lime component and alkaline activator, contains S as lime component of boiling lime}, and as I1, fir-tree activator, soda limestone, as follows. May %: x luminescence powder 0.2-0.3

Compositions of mixtures, May. %:

Semi-aquatic gypsum Aluminum powder Adjuvant melt Lime-pot

The compositions were prepared using a water-gypsum ratio of 0.7, the fluidity of the mixture was 19 cm using a Suttard viscometer and the temperature of the water gate.

Aluminum powder is introduced into the mixing water. Into the resulting water-aluminum slurry is injected and, preliminarily, with a water floor, hygiene, lime-boil} and alkaline silt.

The introduction of a mixture of alkaline melts activates the process of gas formation and makes it possible to obtain a stable gas-gypsum mixture.

The table shows the physicomechanical parameters of gas-gypsum mixtures in the dried state to a constant mass state.

The optimal addition of the alkaline melt is in the range of 1.5-2.0%, and with a further decrease in its amount, an increase in the bulk density of the gypsum is observed.

The use of alkaline melt, which is a waste of caprolactam production, makes it possible to use by-products of chemical enterprises.
