Superabsorberende polymer<\/a> (kaldet SAP) er en revolutionerende type funktionelt polymermateriale, der er kendt for sin enest\u00e5ende sugeevne. I mods\u00e6tning til traditionelle vandabsorberende materialer som silkepapir, bomuld, svamp og fnugmasse kan SAP absorbere hundredvis til tusindvis af gange sin v\u00e6gt og omdannes til en vandsugende hydrogel, der holder p\u00e5 vandet selv under tryk.<\/p>\r\n

\"Superabsorberende<\/p>\r\n\r\n\r\n\r\n

SAP's historie g\u00e5r tilbage til 1960'erne, hvor det amerikanske landbrugsministerium (USDA) begyndte at forske i materialer, der kunne forbedre vandbevaringen i jorden. Deres indsats f\u00f8rte til udviklingen af en harpiks baseret p\u00e5 podning af akrylonitrilpolymer p\u00e5 stivelsesmolekyler, hvilket resulterede i et nyt absorberende materiale, der kunne absorbere mere end 400 gange sin v\u00e6gt uden at frigive flydende vand under tryk.<\/p>\r\n\r\n\r\n\r\n

Samtidig p\u00e5begyndte japanske virksomheder, som ikke var involveret i USDA's forskning, uafh\u00e6ngige unders\u00f8gelser med stivelse, carboxymethylcellulose (CMC), akrylsyre, polyvinylalkohol (PVA) og isobutylenmaleinsyreanhydrid (IMA).<\/p>\r\n\r\n\r\n\r\n

I 1970'erne blev SAP brugt kommercielt for f\u00f8rste gang, prim\u00e6rt i hygiejniske engangsprodukter snarere end til de oprindeligt tilt\u00e6nkte jordforbedringsform\u00e5l.<\/p>\r\n\r\n\r\n\r\n

Gennembruddet kom i 1982, da SAP blev indarbejdet i babybleer i Europa, og kort tid efter blev det introduceret i superabsorberende babybleer i Japan af UniCharm.<\/p>\r\n\r\n\r\n\r\n

Teknologiske fremskridt har siden reduceret brugen af stivelsespodede superabsorberende polymerer i hygiejniske engangsprodukter, hvor de fleste superabsorberende polymerer nu er tv\u00e6rbundne akrylhomopolymerer (typisk natriumneutraliserede) i disse produkter.<\/p>\r\n\r\n\r\n\r\n

I mods\u00e6tning hertil er superabsorbenter, der bruges til jordforbedring, ofte tv\u00e6rbundne akryl-akrylamid-co-polymerer (normalt kaliumneutraliserede). Denne udvikling inden for SAP-teknologi har bidraget v\u00e6sentligt til udviklingen af h\u00f8jeffektive vandopbevaringsmaterialer med forskellige anvendelser p\u00e5 tv\u00e6rs af brancher.<\/p>","protected":false},"excerpt":{"rendered":"
