Description

Technical Field

[0001] The invention relates to the technical field of chemical production, and in particular to a polycarboxylate water-reducing agent monomer production device and a use method thereof. Background Art

[0002] Polycarboxylate water-reducing agent monomer is a high-performance water-reducing agent used in concrete. Polycarboxylate water-reducing agent monomer is mainly an active macromonomer with unsaturated double bonds. There are polyether macromonomers and unsaturated acids in the factory. These monomers form polycarboxylate water-reducing agent through polymerization reaction. Polycarboxylate water-reducing agent monomer needs to be stirred in the container during the production process to make it polymerize. However, when the raw materials are transported into the container, they will carry air. The oxygen in the air is easy to react with the free radicals in the polymerization reaction, consume the free radicals, and thus hinder the reaction. If the exhaust hole is directly opened on the container for natural exhaust, the exhaust speed is slow, which still affects the reaction. The existing technology uses vacuum equipment to vacuum the container to achieve the purpose of exhausting air. However, our company has a large production volume, a large reaction container, and non-stop production all year round. Additional vacuum equipment also needs to be turned on without stopping, which consumes huge electricity and is a considerable expense for the company. In addition, during the stirring process of polycarboxylate water-reducing agent monomer, bubbles will be generated in the liquid raw materials and float on the surface of the liquid raw materials. The existing vacuum equipment cannot puncture the bubbles to release the air in the bubbles, which further reduces the vacuum efficiency. Summary of the invention
