METHOD FOR THE PRODUCTION OF SOLID ACCELERATORS FOR CONSTRUCTION MATERIAL MIXTURES |
| 摘要 |
The present invention relates to a process for producing solid compositions comprising calcium silicate hydrate and at least one water-soluble polymer with cationic structural units, uncharged structural units and/or anionic structural units containing sulpho groups, wherein an aqueous suspension of the calcium silicate hydrate is contacted with the polymer and the mixture is dried by a drum drying process.;/ |

1. Process for producing solid compositions comprising calcium silicate hydrate and at least one water-soluble polymer with cationic structural units, uncharged structural units and/or anionic structural units containing sulpho groups, comprising the following process steps:
A) contacting an aqueous suspension of calcium silicate hydrate with at least one polymer having cationic structural units, uncharged structural units and/or anionic structural units containing sulpho groups and B) drying the product from step A) by a drum drying process at temperatures between 100 and 250° C. |
