Abstract
Description
Technical Field
[0001] The utility model relates to a raw material mixing device for urea resin production, belonging to the technical field of urea resin production. Background Art
[0002] The production of urea resin involves a sophisticated chemical synthesis process, beginning with the mixing of urea and formaldehyde as core raw materials. Under the influence of an alkaline catalyst, these raw materials undergo a condensation reaction under heating to initially form methylol-methylol urea. This reaction then undergoes deep polycondensation to form a linear urea resin. To optimize product performance, adjustments such as acid catalysts, activators, and stabilizers are added for further modification. Ultimately, urea resin can be manufactured into various shapes and sizes through various molding processes, depending on the application requirements. It is widely used in a variety of applications, including molds, films, coatings, adhesives, and agricultural slow-release fertilizer coatings.
[0003] The production of urea resin requires a raw material mixing device. Most existing stirring devices only utilize a single stirring shaft for stirring, which is difficult to meet complex stirring requirements. This leads to uneven mixing of the urea resin, affecting the reaction effect. At the same time, as the viscosity of the urea resin changes, the single stirring shaft may not be able to effectively cope with it, resulting in a decrease in stirring effect and even causing problems such as solid precipitation and material viscosity.
[0004] Therefore, a raw material mixing device for urea resin production is proposed. Utility Model Content
