通过实验,找出EDDP合理的POY-DTY纺丝工艺,并对其性能和结构进行研究.结果发现,由于PEG柔性链段的嵌入,使EDDP切片的Tg、Tc、Tm低于PET,因此在用EDDP进行纺丝时,必须降低干燥、纺丝、热定型温度,但无提高侧吹风速。同时发现,EDDP纤维的染色、吸湿、抗静电效果得到明显改善,织物具有仿毛特点。 相似文献

Experiments were made to find a natural frit which would replace lead and eliminate fritting. Colemanite supplemented by kryolith was found satisfactory, at least at certain temperatures. 相似文献

(1) Some properties of graphite are discussed and industrial applications as a refractory are enumerated. (2) Previous work on graphite, particularly during the World War on graphite crucibles, is reviewed. That work was directed toward finding substitutes for imported graphites and clays. Since peace-time conditions were restored the manufacturers have returned to foreign sources of raw materials and some reasons for this tendency are advanced (3) Analyses of several foreign and domestic graphites are tabulated (4) Reports are given on experiments on the thermal conductivity of clay-graphite bodies.; with the effect of varying percentages of graphite on the conductivity. 相似文献

以二元羧酸乙二酸、丙二酸、丁二酸、顺丁烯二酸和苹果酸为分离对象,三烷基氧膦(TRPO)为络合剂,正辛醇为稀释剂进行了系统的萃取相平衡实验.结果表明,溶质的pKa1和羧酸的亲油性同时影响络合萃取平衡.红外光谱分析表明,萃取剂TRPO与正辛醇之间形成氢键,抑制了对羧酸的萃取,使得TRPO与有机羧酸之间形成1∶1的络合物;负载有机羧酸的红外谱图表明,TRPO萃取有机羧酸为氢键溶剂化历程,负载有机羧酸的TRPO中的P=O键吸收峰的位移与有机羧酸的酸性有关.采用质量作用定律分析方法建立了负载量的表达式,模型拟合精度令人满意. 相似文献
