Superabsorbent polymer, often known as SAP or superabsorbent material (SAM),  High water-absorbent resin finds diverse applications in both consumer and industrial sectors due to its remarkable ability to absorb water and aqueous solutions, absorbing up to 500 times its weight in liquid. Originally developed in the 1960s by the US Department of Agriculture to enhance water conservation in soil, the initial polymer was starch-based, but modern SAP technology shifted to hydrocarbon-derived polymers, High molecular weight water-absorbent material specifically crosslinked acrylic polymers neutralized with sodium.

Superabsorbent polymers have become a staple in the hygiene industry, with around 3 million tons produced annually. Their applications include Hydrogel, Feminine hygiene pads, Fake snow, Wastewater treatment SAP, Agricultural application SAP, Baby and adult diapers, and various incontinence products.

超吸水性聚合物化学》： Superabsorbent polymers used in laminates and airlaids are typically formed through the reaction of acrylic acid monomer with sodium hydroxide and a cross-linking agent, resulting in polyacrylic acid sodium salt. Gel Polymerization is the most common technique, where components are sprayed onto a moving belt in the presence of UV light, causing crosslinking. Suspension Polymerization and Solution Polymerization are alternative methods.

超吸水性聚合物的应用： 当这些聚合物与尿液或血液等水性液体接触时，它们会通过渗透作用吸收水分。这使它们成为个人卫生和失禁产品的理想选择，因为它们即使在压力下也能保留大量液体。但是，当与含盐量高的液体接触时，吸收能力就会下降。

超吸水性聚合物的重要特性：

• 颗粒大小
• 自由膨胀吸收能力
• 负载下的吸收能力
• 保水性能
• 吸水率
• 聚合物渗透性
• 凝胶强度
• 排汗功能
