METHOD OF OBTAINING MOIST ACCELERATOR OF GRIPPING THE GYPSUM

摘要

1. A process for preparing a wet gypsum accelerator setting, comprising: (i) the union of dry gypsum having an average particle size of less than about 15 microns with water to form a moist mixture of gypsum, and (ii) wet grinding the gypsum in the mixture for a time sufficient to reduce the average size the particles of gypsum plaster in wet mixture to obtain a wet gipsa.2 curing accelerator. A method according to claim 1, further comprising combining at least one additive selected from the group consisting of an organic phosphonic compound, a phosphate compound, and mixtures thereof, with the wet gypsum mixture prior to grinding said wet gypsum mixture during or izmelcheniya.3. A method according to claim 1, further comprising combining at least one additive selected from the group consisting of an organic phosphonic compound, a phosphate compound, and mixtures thereof, with dry gypsum to form a wet gypsum smesi.4. A method according to any one of claims 1-3, characterized in that the dry gypsum having an average particle size of less than about 15 micrometers was prepared by dry izmelcheniya.5. A method according to any one of claims 1-3, characterized in that the average size of the dry gypsum particles is about 5 microns or menee.6. A method of hydrating calcined gypsum to form a concatenated matrix of set gypsum comprising forming a mixture of calcined gypsum, water, and humid accelerator setting gypsum, the wet gypsum set accelerator prepared using the dry gypsum having an average particle size of about 15 microns or less to form thereby linked matrix gipsa.7 cured.
