聚氨基甲酸酯泡沫塑料简称聚氨酯泡沫塑料,由聚醚(或聚酯)树脂与多异氰酸酯反应发泡制得,是常见的一种生活用品。软性泡沫塑料具有多孔网状结构、表面积大和弱硷性阴离子交换剂的性质,对多种无机或有机物有吸着作用,在气-固、气-液和液-固体系中可用作吸着剂或吸附剂;同时,泡沫塑料还能吸附一定量的各种有机萃取剂,而且水力学性质很 Polyurethane foam referred to as polyurethane foam, polyether (or polyester) resin and polyisocyanate reaction foaming system, is a common daily necessities. Flexible foams have the property of porous networks, large surface area and weakly basic anion exchangers, adsorbable to a wide range of inorganic or organic compounds and are useful as sorbents in gas-solid, gas-liquid and liquid-solid systems Or adsorbent; the same time, the foam can also adsorb a certain amount of a variety of organic extractant, and very good hydraulics
