黄磷罐式集装箱的强度计算与测试

1黄磷罐式集装箱概述(1)物理化学性质黄磷又称白磷,英文名phosphorus,分子式4P,分子量:128.89,国际危险品联合国代码:un1381。白磷在贮存时,由于受光和杂质的影响变为浅黄色,故习惯上称黄磷,其外观为黄色蜡状固体,质软,可用刀切割。相对密度1.82(20℃),熔点44.1℃,沸点280℃,不     

我国黄磷公海铁联运新模式

1我国黄磷运输模式现状1.1主要运输模式我国黄磷主要产地为云南、贵州和四川等省份;华东地区是我国黄磷主要消耗地,每年消耗黄磷约45万t。目前我国黄磷主要运输模式为陆路运输:黄磷需求量较少的企业采用全程公路运输模式,运输成本高昂;黄磷铁路运输成本则相对较低。我国黄磷铁路运输模式主要有:(1)公铁联运,即黄磷生产厂使用额定装载量为25 t的罐式汽车将黄磷通过公路运输至昆明铁路站后直接装入铁路专用     

罐式集装箱运输黄磷的经济性分析

介绍黄磷的性质及其在罐式集装箱储运过程中的特殊要求,确定罐式集装箱运输黄磷的合理充装量,根据《铁路货物运价规则》分析运输相关费用,并以20英尺罐式集装箱运输黄磷为例进行实例计算,说明使用罐式集装箱运输黄磷安全、经济、便利、高效。     

关于黄磷渣作为粗骨料替代废石的可行性研究

开展黄磷渣作为粗骨料应用到矿山充填技术当中对节约充填成本、提高黄磷渣的利用效率以及环境保护有着重要意义。本次研究主要是对黄磷渣作为粗骨料应用到矿山充填开采当中的可行性,通过对相同条件下废石充填体试块与黄磷渣充填体试块在不同的龄期强度进行对比,探究黄磷渣作为粗骨料替代废石的可行性进行研究。实验表明:在不同的水泥添加量以及不同的粗骨料占比情况下,黄磷渣都能对废石起到很好的替代效果,黄磷渣作为粗骨料应用到矿山充填当中是完全可行的。     

Experimental observation and computer simulation on non-equilibrium grain-boundary segregation kinetics of phosphorus

An experimental study and computer simulation on non-equilibrium grain-boundary segregation kinetics and the critical time for phosphorus in 12Cr1MoV steel( which is used in steam pipeline of ships)are put forward in this paper. The segregation level of phosphorus with solution temperature 1050 ℃ at the isothermal holding temperature of 540 ℃ ,have been measured at grain-boundaries. A non-equilibrium grain-boundary segregation kinetics curve of phosphorus is given, The critical time for phosphorus non-equilibrium grain-boundary segregation is about 500 h at 540 ℃ for the experimental steel, When the holding time is longer than 1 500 h, non-equilibrium segregation disappears and the level of segregation reaches full equilibrium, The simulation using the kinetic equations of non-equilibrium grain-boundary segregation is in good accordance with the experimental observation for phosphorus in steel 12Cr1 MoV. The non-equilibrium grain-boundary segregation kinetic model is therefore proved.     

The measure and decision of technical risk in the development of naval vessels

The risks in development of navy vessels were explored, The resources of technical risk in the design and development of vessels were mentioned, It was pointed that technical risk dominated the other risk components. Based on the writers＇ understanding and experience from risk analysis and risk ,nanagement to the development of a navy vessel, four measure indexes of technical risk were presented. The decision criteria and the rules corresponding to the indexes were estahlished by the statistic information,
