Description

Technical Field

[0001] This utility model relates to sodium polyacrylate processing equipment, and more particularly to a sodium polyacrylate processing equipment with a curing structure. Background Technology

[0002] Sodium polyacrylate (SPA) is a high-molecular-weight compound with a variety of excellent properties. It can absorb hundreds of times its own weight in water to form a gel, is resistant to acids, alkalis, and high temperatures, has stable chemical properties, and good flexibility, making it widely used in many fields. In one SPA production process, water is used as the reaction solvent. Water and acrylic acid as the main material are added to a reaction vessel, along with various additives. After nitrogen deoxygenation, hydrogen peroxide, peracetic acid, vitamin C, sodium sulfite, ferrous sulfate, and other redox agents are added to initiate a redox reaction, forming a gel. After the reaction, the gel is crushed, treated with sodium hydroxide, dried, pulverized, and finally sieved to obtain the final product. Common SPA processing equipment places the processed product in a constant-temperature device, heating it at a specific temperature to further cross-link the SPA molecular chains, enhancing its stability and mechanical strength. However, this constant-temperature device is independent of the processing equipment. The transfer of SPA to the device can easily lead to contamination, material loss, temperature fluctuations, humidity changes, physical damage, and time delays, affecting production efficiency and product consistency. Therefore, structural optimization is necessary to overcome these shortcomings. Utility Model Content
