Description

Technical Field

[0001] This utility model relates to the field of resin production technology, and in particular to a batching and cooling device for sodium polyacrylate superabsorbent resin. Background Technology

[0002] Sodium polyacrylate superabsorbent polymer (SAP) is an important class of functional polymer materials. Its molecular structure contains a large number of carboxyl anions, giving it a unique water absorption capacity. It can rapidly absorb and retain liquids hundreds or even thousands of times its own weight, and maintain excellent water retention even under pressure. This superior water absorption and retention property makes it widely used in hygiene products (such as diapers and sanitary napkins), agricultural and forestry water conservation (soil improvement, seed coating), and industrial dehydration (oil-water separation, wastewater treatment).

[0003] Sodium polyacrylate superabsorbent polymer (SAP) resin is mainly composed of core raw materials such as acrylic acid, sodium hydroxide, crosslinking agent, and initiator, as well as additives such as dispersant and salt-resistant modifier. Precise proportioning and thorough mixing of each component are crucial for optimizing resin performance. However, during the mixing process, after the acrylic acid and additives are mixed, the reaction system temperature rises rapidly due to the action of the initiator. Without effective cooling, the high temperature accelerates the decomposition of the initiator, leading to abnormal molecular chain breakage and branching, reducing the resin's water absorption rate. Simultaneously, the high temperature causes excessive crosslinking, forming an overly dense network structure that hinders water molecule penetration, weakening water absorption and retention capacity. However, existing mixing devices lack relevant cooling structures, thus affecting the performance of SAP resin. Utility Model Content

[0023] Specifically, the cold water tank 1 is cylindrical with a cold water outlet 11 at the bottom, which is used to transport the low-temperature cooling water in the cold water tank 1 to the mixing tank 2 to provide a cold source for the cooling process of sodium polyacrylate superabsorbent resin. The return water port 12 at the top of the cold water tank 1 is used to recover the cooling water after it has been heated by heat exchange in the mixing tank 2 for recycling. The cold water tank 1 is equipped with a cooling structure to cool the water, so that the water can be kept at a suitable low temperature.
