A Superabsorberende polymer<\/a> (SAP) er en type hydrogel, der, n\u00e5r den er tv\u00e6rbundet, har evnen til at absorbere vandige opl\u00f8sninger gennem hydrogenbinding med vandmolekyler. I deioniseret og destilleret vand kan en SAP absorbere 300-1200 gange sin v\u00e6gt og omdannes til en gel. Absorptionsevnen falder dog markant til omkring 50 gange sin v\u00e6gt, n\u00e5r den uds\u00e6ttes for en 0,9% saltopl\u00f8sning.<\/p>\r\n\r\n\r\n\r\n

Absorptionsevnen og h\u00e6velse af en SAP bestemmes af typen og omfanget af tv\u00e6rbindingsmidler, der anvendes i produktionen. Tv\u00e6rbundne SAP'er med lav densitet har generelt h\u00f8jere absorberingsevne og h\u00e6velse, hvilket resulterer i en bl\u00f8dere og mere kl\u00e6brig geldannelse. P\u00e5 den anden side har polymerer med h\u00f8j tv\u00e6rbindingst\u00e6thed lavere absorberingsevne og svulmer mindre op, men de giver en fastere gelstyrke, der bevarer partikelformen selv under moderat tryk.<\/p>\r\n\r\n\r\n\r\n

Mekanismen for, hvordan SAP'er fungerer, involverer et netv\u00e6rk af polymerk\u00e6der, der er forbundet med hinanden ved hj\u00e6lp af tv\u00e6rbindingsmidler. Denne netv\u00e6rksstruktur g\u00f8r det muligt for vandmolekyler at blive trukket ind i polymeren gennem osmose, hvor de lagres i det indre af polymernetv\u00e6rket.<\/p>\r\n\r\n\r\n\r\n
