Waste Polyurethane(废聚氨酯)研究综述
Waste Polyurethane 废聚氨酯 - This study is to replace part of the styrene-butadiene-styrene (SBS) modifier with waste polyurethane (WP), for preparing WP/SBS composite modified asphalt, as well as exploring its properties and microstructure. [1]本研究以废聚氨酯（WP）替代部分苯乙烯-丁二烯-苯乙烯（SBS）改性剂，制备WP/SBS复合改性沥青，并探索其性能和微观结构。 [1]
waste polyurethane foam 废聚氨酯泡沫
In this review, glycolysis of waste polyurethane foam (PUF) materials with different glycols and catalysts, especially metallic ones were considered, and the effect of some additional parameters such as the nature of glycol, catalyst, temperature and material ratio were discussed too. [1] Structure and behaviour of gypsum composites, prepared from flue gas desulfurization binder and three types of fine fillers (silica sand, perlite, expanded clay aggregate and waste polyurethane foam) were studied. [2] Low-cost activated carbons were prepared from waste polyurethane foam by physical activation with CO2 for the first time and chemical activation with Ca(OH)2, NaOH, or KOH. [3] Waste polyurethane foam was conducted to investigations in the form of a bulk sample and sorted grain-size samples with a goal to detect the chemical composition of the pyrolysate. [4]在这篇综述中，考虑了废聚氨酯泡沫（PUF）材料在不同的乙二醇和催化剂，特别是金属材料的糖酵解过程中，并讨论了一些附加参数如乙二醇的性质、催化剂、温度和材料比例的影响。 [1] 研究了由烟气脱硫粘合剂和三种细填料（硅砂、珍珠岩、膨胀粘土骨料和废聚氨酯泡沫塑料）制备的石膏复合材料的结构和性能。 [2] 首次采用 CO2 物理活化和 Ca(OH)2、NaOH 或 KOH 化学活化的方法从废聚氨酯泡沫中制备低成本活性炭。 [3] 以散装样品的形式对废聚氨酯泡沫进行调查，并对粒度样品进行分类，目的是检测热解物的化学成分。 [4]
waste polyurethane elastomer 废聚氨酯弹性体
Glassy carbon foam (GCF) catalyst supports were synthesized from waste polyurethane elastomers by impregnating them in sucrose solution followed by pyrolysis and activation (AC) using N2 and CO2 gas. [1] In this work, activated carbon foams (ACFs) were produced from waste polyurethane elastomer templates using different synthesis pathways, including a novel one-step method. [2]玻璃碳泡沫 (GCF) 催化剂载体是由废弃的聚氨酯弹性体合成的，方法是将它们浸渍在蔗糖溶液中，然后使用 N2 和 CO2 气体进行热解和活化 (AC)。 [1] 在这项工作中，活性炭泡沫 (ACF) 是由废弃的聚氨酯弹性体模板使用不同的合成途径生产的，包括一种新颖的一步法。 [2]
