Analysis of the Ecological and Toxicological Properties of Dyes with Reference to Safety Data Sheet

In recent years,the public awareness and concern forthe environment has increased significantly.This has re-sulted in tougher legislation and more stringent standardsfor the industry to comply.In the past,the cost,fast-ness properties and colour yield were the prime consider-ations when dyeing systems were to be selected.Today,special emphasis is also laid on the environmental prop-erties of the dyes.In this paper,the various ecologicaland toxicological properties from safety data sheet of dif-ferent dye classes were studied so as to assess the impactof the textile dyeing effluent on the environment qualita-tively and quantitatively.The results showed that eachdye class produces waste of vastly differing quantities and characteristics.Moreover,the variability of the pollu-tion parameters within each dye class was found to be very large,thus it was believed that substituting dyes of lower degree of pollution to the environment can be aneffective means to reduce the degree of pollution of the dyeing efflue

温度和应变率对拉伸载荷下记忆合金本构关系的影响

用于高温Split Hopkinson Bar(SHB)试验的新型快速加热电炉，可在1min左右将试件加热至500度，最高可加热至1000度，且金属材料和非金属材料均可加热，在20－800度和0．00208－350s^-1范围内研究了温度和变率对拉伸载荷下铁基形状记忆合金本构关系的影响，结果表明，随着应变率提高，材料强度提高，延伸率降低，材料强度，延伸率及应变率敏感性随温度升高而降低。
