强化管理:一水多用,向废水资源化迈进

我厂是一个装机容量120万千瓦的大型火电企业,从八四年一号机组投产到现在,水的问题一直困扰着我们。据不完全统计,八九年因缺水停机1574小时,累计少发电量29632.SKWh,九零年因缺水停机448小时,累计少发电量8064万KWh,水的问题不解决,我们就很难达到满出力运行。根据原设计我厂六台200MW国产机组(四台湿冷冷机组,二台空冷机组)日用水量     

Polylactide (PLA)—Halloysite Nanocomposites: Production, Morphology and Key-Properties

To evaluate the potential of halloysite nanotubes (HNT) as nanofiller for polylactide (PLA), various nanocomposites have been successfully produced by melt-blending the polyester matrix with HNT (HNT(QM)). HNT were also surface treated by silanization reaction with 3-(Trimethoxysilyl) propyl methacrylate (TMSPM). The morphology, thermal, tensile and impact strength properties of the nanocomposites containing 3?C12?% HNT were evaluated and compared to those of pristine (unfilled) PLA. The nanocomposites were characterized by higher rigidity (with Young??s modulus increasing with HNT loading), higher tensile strength (about 70?MPa at 6?% HNT(QM)), whereas the elongation at break and impact strength did not decrease. As demonstrated under dynamic solicitation (DMA), melt-blending PLA with HNT led to enhancement of storage modulus (E??) and offers the possibility to use PLA in applications requiring higher temperatures of utilization. However, with few exceptions, TGA and DSC measurements did not reveal important changes of thermal parameters. The surface silanization treatment proved to improve the quality of the nanofiller dispersion even at higher loading. As a result, good thermal stability associated to high tensile strength, and noticeable increases in impact properties were recorded. Furthermore, enhanced nucleating ability and crystallization kinetics of the PLA matrix were revealed as specific characteristics.
