耐热粉末铝合金筒体热旋成形试验

介绍了喷射沉积耐热铝合金管坯经挤压变形 ,变薄旋压筒体的研制过程 ;重点论述了热旋成形筒体的工艺路线。试验探讨了耐热铝合金的旋压温度为 35 0～ 45 0℃ ,道次变薄率约为2 0 % ,累计变薄率约 5 0 % ,需中间退火 ,退火温度宜取 35 0℃。热旋结果认为 ,喷射沉积耐热粉末铝合金铸坯直接热旋成形困难 ,需经挤压比大于 4的变形致密 ,有助于热旋成形。耐热粉末铝合金挤压坯加热变薄旋压 ,应采用小压下量多道次的变形过程 ,逐渐细化晶粒组织 ,才能旋出综合性能良好的筒形件。

Production of laccase by Coriolus versicolor and its application in decolorization of dyestuffs: (Ⅱ) Decolorization of dyes by laccase containing fermentation broth with or without self-immobilized mycelia

The capability of decolorization for commercial dyes by Coriolus versicolur fermentation broth containing laccase with or without immobilized mycelium was evaluated.With cell-free fermentation broth containing laccase,high decolorization ratio was achieved for acid orange 7,but not for the other dyes concerned.The immobilized mycelium was proved to be more efficient than the cell-free system.All the four dyestuffs studied were found being decolourized with certain extent by immobilized mycelium.The repeated-batch decolorization was carried out with satisfactory results.The experimental data showed that the continuous decolorization of wastewater from a printing and dyeing industry was possible by using self-immobilized C.Versicolor.     

The effect of heating temperature of thin film transistor-liquid crystal display (TFT-LCD) optical waste glass as a partial substitute partial for clay in eco-brick

In order to fulfill the current WEEE directives, the traditional approach to manage thin film transistor-liquid crystal display (TFT-LCD) waste glass is inadequate. It is a serious opportunity to achieve resource conservation, reduction, stabilization and safety of management of TFT-LCD in the near future. To assist in achieving these goals, this study investigated the sintering characteristics and material properties of TFT-LCD waste glass, which can be pulverized and ground and subsequently blended with clay, at various substitution levels (0–40%) and finally fired from 800 °C to 1000 °C to make eco-brick. The brick thus produced was analyzed to determine variations in weight losses on ignition, 24-h absorption, bulk density, shrinkage, compressive strength and microstructure changes. The results for specific gravity, water adsorption, and compressive strength revealed that bricks made from mixtures containing TFT-LCD waste glass met the general requirements for bricks. The advantages of less water absorption, less weight loss on ignition, and a gain in compressive strength in the clay-TFT-LCD waste glass bricks should encourage the use of TFT-LCD waste glass as a brick additive.

中国近海沉积物在生源要素循环中的功能

中国近海沉积物中生源要素的含量与其粒度、河流输入等诸多因素有关。一般沉积物粒度由粗到细 ,有机质含量由低到高 ,OC ,N ,P的含量递增 ,S和Si含量递减。沉积物的生物地球化学环境涉及到Eh ,pH ,温度 ,OC含量 ,Fe3 /Fe2 值 ,水动力条件 ,沉积物的颗粒大小和间隙水的S体系 ,以及生物扰动等因素 ,它们影响着沉积物中生源要素的早期成岩过程和循环。一般而言 ,中国近海沉积物—海水界面S2 -,HS-,H4SiO4,PO43 -,NH4 的扩散通量是从沉积物向上覆水 ,而SO42 -,HCO3 -,NO3 -,NO2 -的扩散通量从上覆水向沉积物中扩散。生物扰动对沉积物—海水界面生源要素的循环起重要作用。
