固体废弃物低温烧制优等节能保温砖强度机理及热性能分析

采用废弃物粉煤灰和煤矸石为主要原料焙烧实心墙体保温砖.正交实验优化结果为:焙烧温度950℃,低于实心粘土砖100℃的焙烧温度,属于低温焙烧.焙烧周期24 h,粉煤灰和煤矸石的掺量比是60%:35%,掺膨胀珍珠岩的保温砖B7抗压强度为30.25 MPa,达到普通粘土砖MU30优等级;导热系数为0.400 W/(m·K),低于普通粘土砖的导热系数0.78 W/(m·K);此外,B7的XRD图谱出现明显的石英、莫来石衍射特征峰及TGA-DTA图谱在900～1 200℃的区间,随着温度的升高,坯体吸热开始熔融玻化,产生晶型转变,使力学性能得到提高;SEM扫描可见:经950 ℃焙烧后,球体状的实心玻璃珠、珠状皱晶的珍珠岩、絮凝状的铝硅酸盐相,原料颗粒之间的间隙被枯性玻璃质所填充,使B7产生很高的力学强度.     

不同抗震设计的砖混结构校舍抗震性能对比

砖混结构在我国中小学校舍中所占的比例较高,在近几年发生的地震中,其震害十分明显。以中原地区某县中小学校舍鉴定汇总结果为基础,取某砖混结构教学楼为例,分未考虑抗震设计、考虑抗震设计和未考虑抗震设计但进行了抗震加固改造三种工况,以PKPM软件对其进行抗震性能对比分析,并以此方法对该县中小学砖混结构校舍进行抗震性能计算及对比分析。结果表明,校舍中考虑抗震设计的工况比其它工况的抗震性能高,该地区2000年前的校舍需改造加固。

Wood waste management practices and strategies to increase sustainability standards in the Australian wooden furniture manufacturing sector

This study assesses the wood waste generation and its associated true cost which Australian wooden furniture manufacturing companies encounter and are exposed to. The assessment aims to create awareness and facilitate understanding within the wooden furniture manufacturing industry about how much wood is wasted into the production process and how this is translated in financial terms, how wood waste can be reduced, what can and can't be recycled and what services are available to assist businesses with recycling. The results indicate that during processing, 7% up to 40–50% of the annual supply of wooden raw material become residues. The costs connected directly to these wastes represent 2–8% of the turnover.

Pollution prevention in the pharmaceutical industry

The pharmaceutical industry traditionally uses complex batch-type processes in the manufacture of medicines, although the production of specific medicines by continuous processes is currently envisaged. Due to the diversity of these processes, it is difficult to define a general set of waste prevention guidelines that would apply to all drug manufacturing. The most applicable methods of prevention can, however, be delineated for each of the five steps in the pharmaceutical manufacturing, i.e. (i) research and development, (ii) chemical synthesis, (iii) natural product extraction, (iv) fermentation and (v) product formulation. Waste streams generally arise from cleaning and sterilising equipment, chemical spills, rejected by-products and the processes themselves. Prevention mainly involves waste reduction by materials substitution, process modification/optimisation, waste stream segregation and solvent waste recycling. These measures are assessed and lead to guidelines for waste minimisation methods according to the waste streams under scrutiny.
