It has high water absorption function of absorbing water hundreds to thousands times heavier than itself, and excellent water retention performance. Once water is absorbed and swelled into hydrogel, it is difficult to separate water even under pressure. Super absorbent resin is a functional polymer material containing a large number of hydrophilic groups.
Because of its high liquid absorption capacity, fast liquid absorption speed and strong liquid retention capacity, it is widely used in physiological health products, such as female sanitary napkins, diapers, adult multifunctional nursing pads, absorbent paper, pet pads and so on. It makes this kind of products lighter, smaller and more comfortable, which brings good news to people and is an irreplaceable ideal product in the field of sanitary products.
Environmental protection and non-toxic characteristics of water-absorbent resin
Super absorbent polymer has the advantages of non-toxicity, no irritation to human body, no side effects and no coagulation, and has been widely used in medical field in recent years. For example, it is used for external ointment with high water content and comfortable use.
The production of medical bandages and cotton balls can absorb bleeding and secretions from surgery and trauma and prevent suppuration; Make anti-infective artificial skin, let moisture and drugs pass through, but microorganisms can't.
With the development of science and technology, environmental protection has been paid more and more attention. If you put the super absorbent resin into a bag that can be dissolved in sewage and immerse the bag in sewage, when the bag is dissolved, the super absorbent resin can quickly absorb the liquid and solidify the sewage.
In the electronic industry, super absorbent polymers can also be used as humidity sensors, humidity measurement sensors and water leakage detectors. Superabsorbent polymers can be used as heavy metal ion adsorbents and oil-absorbing materials.
