Description

A concrete admixture reaction device

technical field

Background technique

Concrete admixtures (English: concrete admixtures) are referred to as admixtures, which refer to substances added to improve the performance of concrete during the process of mixing concrete. The amount of concrete admixture is generally not more than 5% of the cement quality. The quality of concrete admixture products must meet the requirements of the national standard "Concrete Admixtures" (GB 8076-2008). More and more attention is paid to the application of concrete admixtures in engineering. The addition of admixtures plays a certain role in improving the performance of concrete, but the selection, addition method and adaptability of admixtures will seriously affect its development.

Among them, the most commonly used type of concrete admixtures are high-molecular polymers, which require the use of small monomers to generate macromolecular polymers through polymerization. The current reaction device usually includes a reaction kettle, a heating mantle and a stirring device. When in use, the monomer is added to the reaction kettle, and then the heating mantle is used to heat the monomer in the reaction kettle, and the stirring device stirs at the same time. However, as the reaction progresses, the monomers gradually polymerize macromolecules, and the solution in the reactor becomes viscous, resulting in an increase in the time required for the temperature of the jacket to be transferred from the surface of the reactor to the center of the reactor, resulting in an increase in the temperature of the reactor. The temperature is not uniform and the temperature difference is large, so that the quality of the obtained polymer product is relatively poor.
