| titleOfInvention | A kind of water reducing agent preparation process |
| abstract | The invention belongs to the technical field of water-reducing agents, and in particular relates to a process for preparing a water-reducing agent, comprising the following steps: step 1, preparing a first mixed solution: after mixing and stirring a formaldehyde solution and acetaldehyde, heating and standing to obtain a first mixed solution liquid; step 2, prepare the second mixed solution: mix and stir sodium sulfite, sodium metabisulfite, pyruvic acid, water, HSC water reducing activator, sulfanilic acid and sodium lignosulfonate, and let stand, dropwise add the first mixed solution to obtain the second mixed solution; step 3, adding air-entraining and retarding: adding air-entraining agent and lignosulfonic acid calcium salt to the second mixed solution to obtain a water reducing agent; wherein, step one adopts a water reducing agent The agent preparation device is completed. The invention can ensure that the raw material of the aliphatic water-reducing agent is heated uniformly, and can ensure that the volatilized formaldehyde is dropped back to the raw material of the aliphatic water-reducing agent, thereby ensuring the performance of the aliphatic water-reducing agent. |
