Fire-retardant gels are superabsorbent polymer slurries with a "consistency almost like petroleum jelly."〔 (【引用サイトリンク】 author = The Associated Press )〕 Used as fire retardants, they can be used for structure protection and in direct-attack applications against wildfires.〔 (【引用サイトリンク】 url = http://firegel.com/Documents/CDF_Evaluation_Letter.pdf ) 〕〔 (【引用サイトリンク】 UDSA Forest Service Specification for Water Enhancers (gels) for Wildland Firefighting ) 〕 == History == The practical use of gels was limited until the 1950s as advances in copolymerization techniques led to reproducible, batchwise preparation of swellable resins with uniform cross-linking.〔 〕 This technology was later used in the development of a "substantially continuous, adherent, particulate coating composition of water-swollen, gelled particles of a crosslinked, water-insoluble, water-swellable polymer."〔 〕 The water-absorbent polymers in fire-retardant gels are similar to those used in diapers.〔 (【引用サイトリンク】 BARRICADE II FIRE BLOCKING GEL MSDS ) 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fire retardant gel」の詳細全文を読む スポンサード リンク
