Eritt\u00e4in imukykyinen polymeeri<\/a> (j\u00e4ljemp\u00e4n\u00e4 SAP) on vallankumouksellinen funktionaalinen polymeerimateriaali, joka tunnetaan poikkeuksellisista imukykyominaisuuksistaan. Toisin kuin perinteiset vett\u00e4 imev\u00e4t materiaalit, kuten pehmopaperi, puuvilla, sieni ja p\u00f6rr\u00f6inen massa, SAP pystyy imem\u00e4\u00e4n itseens\u00e4 satoja tai jopa tuhansia kertoja painonsa verran vett\u00e4 ja muuttumaan vedest\u00e4 turpoavaksi hydrogeeliksi, joka pid\u00e4tt\u00e4\u00e4 vett\u00e4 jopa paineen alaisena.<\/p>\r\n

SAP:n historia ulottuu 1960-luvulle, jolloin Yhdysvaltain maatalousministeri\u00f6 (USDA) aloitti tutkimusty\u00f6n, jonka tarkoituksena oli tutkia materiaaleja, jotka parantavat maaper\u00e4n vedensuojausta. Heid\u00e4n ponnistelunsa johtivat hartsin kehitt\u00e4miseen, joka perustui akryylinitriilipolymeerin varttamiseen t\u00e4rkkelysmolekyyleihin, ja tuloksena oli uusi imukykyinen materiaali, joka kykeni imem\u00e4\u00e4n yli 400 kertaa painonsa verran vett\u00e4 ilman, ett\u00e4 nestem\u00e4ist\u00e4 vett\u00e4 vapautuu paineen alaisena.<\/p>\r\n\r\n\r\n\r\n

Samaan aikaan japanilaiset yritykset, jotka eiv\u00e4t osallistuneet USDA:n tutkimukseen, aloittivat itsen\u00e4isi\u00e4 tutkimuksia t\u00e4rkkelyksell\u00e4, karboksimetyyliselluloosalla (CMC), akryylihapolla, polyvinyylialkoholilla (PVA) ja isobutyleenimaleiinihappoanhydridill\u00e4 (IMA).<\/p>\r\n\r\n\r\n\r\n

1970-luvulle tultaessa SAP:t\u00e4 k\u00e4ytettiin ensimm\u00e4ist\u00e4 kertaa kaupallisesti, l\u00e4hinn\u00e4 kertak\u00e4ytt\u00f6isiss\u00e4 hygieniatuotteissa eik\u00e4 niink\u00e4\u00e4n sen alkuper\u00e4isess\u00e4 k\u00e4ytt\u00f6tarkoituksessa maaper\u00e4n parantamisessa.<\/p>\r\n\r\n\r\n\r\n

L\u00e4pimurto tapahtui vuonna 1982, kun SAP sis\u00e4llytettiin vauvanvaippoihin Euroopassa, ja pian sen j\u00e4lkeen UniCharm otti sen k\u00e4ytt\u00f6\u00f6n eritt\u00e4in imukykyisiss\u00e4 vauvanvaipoissa Japanissa.<\/p>\r\n\r\n\r\n\r\n

Teknologian kehitys on sittemmin v\u00e4hent\u00e4nyt t\u00e4rkkelykseen vartetun superabsorbenttisen polymeerin k\u00e4ytt\u00f6\u00e4 kertak\u00e4ytt\u00f6isiss\u00e4 hygieniatuotteissa, ja useimmat superabsorbentit ovat nyky\u00e4\u00e4n ristisilloitettuja akryylihomopolymeerej\u00e4 (tyypillisesti natriumilla neutraloituja) n\u00e4iss\u00e4 tuotteissa.<\/p>\r\n\r\n\r\n\r\n

Sen sijaan maaper\u00e4n parantamiseen k\u00e4ytett\u00e4v\u00e4t superabsorbentit ovat usein ristisilloitettuja akryyli-akryyliamidikopolymeerej\u00e4 (yleens\u00e4 kaliumneutraloituja). T\u00e4m\u00e4 SAP-teknologian kehittyminen on edist\u00e4nyt merkitt\u00e4v\u00e4sti eritt\u00e4in tehokkaiden vedenpid\u00e4tysmateriaalien kehitt\u00e4mist\u00e4, joilla on monenlaisia sovelluksia eri teollisuudenaloilla.<\/p>","protected":false},"excerpt":{"rendered":"
