吸水剂即高吸水性树脂(Super absorbent resin),是一种高分子材料,1973年由美国农业部首先合成。它与水接触时,能够吸收和保持相当自身重量数百倍至数千倍的水分,因而在工业、农业及医疗卫生等方面有广泛用途。近年来,美国、日本等国已大量生产吸水剂,我国吉林石油化工研究所、北京化学纤维研究所、新疆化工设计院等单位也相继开展了研制工作,有的已建成中试工厂进行小批量生产。
Super absorbent absorbent water absorbent resin (Super absorbent resin), is a polymer material, in 1973 by the United States Department of Agriculture first synthesis. When it comes in contact with water, it absorbs and retains a considerable amount of water hundreds to thousands of times its own weight and therefore has a wide range of uses in industry, agriculture and healthcare. In recent years, the United States, Japan and other countries have mass-produced water-absorbing agent, China’s Jilin Petrochemical Research Institute, Beijing Chemical Fiber Institute, Xinjiang Chemical Design Institute and other units have also carried out research and development work, and some have been completed pilot plant for small quantities produce.
