Description

Technical Field

[0001] The utility model belongs to the technical field of AKD sizing agent processing, in particular to an AKD neutral sizing agent homogenizer. Background Art

[0002] AKD sizing agent is an unsaturated lactone. The product is a waxy solid that is insoluble in water. Its melting point is about 51-52°C. It is a reactive neutral paper sizing agent. AKD used in paper sizing agent must be made into an emulsion. The particle size of the product is about 0.5-2μm. The emulsion is white and very easy to hydrolyze, so the general storage period is short, only 3-6 months. Due to the development of synthesis and emulsification technology, the solid content of AKD sizing agent emulsion can reach 40% or more, and its hydrolysis and migration tendency is greatly limited.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in the technology: the processing of AKD sizing agent requires that its raw materials be homogenized and emulsified before they can be formed. The homogenizer currently used in the homogenization and emulsification process of the AKD sizing agent raw materials (for example, the patent CN201921282436.9 - a homogenizer emulsifier dedicated to AKD sizing agent) usually has a fixed stirring mechanism that can neither be raised nor lowered, which results in a very limited range of homogenization, and the raw materials in various places in the homogenization tank cannot be effectively homogenized, resulting in poor final homogenization effect.

[0004] Therefore, we propose an AKD neutral sizing agent homogenizer to solve the above problems. Utility Model Content
