我国碳达峰碳中和目标、碳捕集利用储存的需求为火电厂烟气脱硫技术的进步带来了机遇,某公司开发的新型脱硫剂提升了其脱硫脱碳的性能,但其对脱硫塔内部树脂基玻璃鳞片内衬作用机制仍不明确,存在应用风险。为了研究乙烯基玻璃鳞片内衬防腐涂层耐新型纳米脱硫剂腐蚀老化作用的影响,本研究设计开展含不同浓度新型脱硫剂的浆液浸泡模拟试验。通过对浸泡试验前后的涂层样品进行宏观质量与外观、表面微观形貌、巴氏硬度、耐磨性能和力学强度测试,分析了涂层腐蚀老化行为与规律,揭示了其可能的失效机理。试验结果表明随着浆液浸泡试验时间的增加,涂层样品出现不同程度的腐蚀老化现象,样品质量吸水增重,表层出现鼓包现象,SEM结果表明表面局部粉化,样品巴氏硬度、耐磨性能、力学强度均呈现较明显的下降趋势。因此,本研究建议在树脂基玻璃鳞片防腐涂层的实际应用中应提高性能和工艺要求,选择合适的玻璃鳞片种类以及树脂基材料,将有利于新型纳米脱硫剂的成功应用。  相似文献

Large areas of Latvia are contaminated with industrial waste: metallurgical slag, fly-ash, etching refuse, peat, and coal ash as well as glass waste which often contain dangerous substances. From the environmental point of view this waste should be neutralised. As this waste also contains valuable chemical compounds, it can be considered as a raw material for the generation of new materials. One method of utilisation is to produce recycled materials — street plates, decorative tiles, or floor tiles. Dense sintered glassceramics with a water uptake of 0.34–3.23 wt.%, a final density of 2.93–3.05 g/cm3, and a bending strength of 80–96 MPa have been created from industrial waste. The mast chemically durable glassceramics contained clay additions. Thus, the material containing only waste had a durability (mass loss) of 3.02% in 0.1 N HCl, while the composition containing 30% clay addition had a durability of 0.2% in 0.1 N HCl.  相似文献

Humans will continue to adapt to an increasingly technological world. But are there costs to such adaptations in terms of human well being? Toward broaching this question, we investigated physiological effects of experiencing a HDTV quality real-time view of nature through a plasma display “window.” In an office setting, 90 participants (30 per group) were exposed either to (a) a glass window that afforded a view of a nature scene, (b) a plasma window that afforded a real-time HDTV view of essentially the same scene, or (c) a blank wall. Results showed that in terms of heart rate recovery from low-level stress the glass window was more restorative than a blank wall; in turn, a plasma window was no more restorative than a blank wall. Moreover, when participants spent more time looking at the glass window, their heart rate tended to decrease more rapidly; that was not the case with the plasma window. Discussion focuses on how the purported benefits of viewing nature may be attenuated by a digital medium.  相似文献

The paper considers the participation of households in recycling programmes in areas of multi-storey, low income housing which are often considered unattractivefor such programmes.A model of the material recycled is presented together with a review of socio-economic, housing, technological, policy and other factors influencing household recycling. This is followed by a case study of two areas in the city of Edinburgh. Results suggest that the level of recycling is influenced by collection methods, for all materials except glass, with half of the recyclers starting as a result of the introduction of kerbside collection. Housing characteristics such as the storey-level in buildings without lifts , household size and access to cars all influenced recycling participation rates. Housing tenure was not found to be significant. This suggests that well designed kerbside collection programmescan have a significant impact in areas with high levels of multi-storey dwellings, low income and public housing.  相似文献

有机涂层户外失效分析及对策   总被引:1,自引:0,他引:1

我国气候类型复杂,有机涂层在一些典型气候条件下经过一段时间的户外暴露后都会出现粉化、颜色变化、剥落、沾污等明显变化.综合起来分析,当地太阳辐射强度、辐射量、温湿度等是有机涂层失效的主要因素;同时空气中的污染物、沙尘等也加速了有机涂层失效.因此研制新型户外涂料时要确保有机涂层既能起防护作用,又能起装饰作用,以增强有机涂层...  相似文献

It is a challenge to reduce the ever-increasing flow of waste. In Norway the systems for recycling of organic waste, paper, glass, metals, etc. differ between municipalities, both with regard to organizational and to technological structures. Our hypothesis is that people's attitudes and behaviour may differ with different systems of waste management. People's behaviour and attitudes regarding (organic) waste recycling were investigated in two municipalities with differing technical and organisational systems. Data came from interviews with municipal employees, questionnaires, focus groups and multi-criteria mapping. People seem to be better informed and more positive about organic waste recycling in one of the municipalities (MH, which has recycling of organic waste) than in the other (MS, which has no such recycling). The two municipalities had similar sets of important criteria for waste management (price, environmental friendliness, easy solutions, information). Many participants stated that they had learned from the group process, though only a few reported changed preferences. The institutional context seems to be important for people's behaviour and attitudes towards waste management. This implies that people's recycling behaviour does not only depend on technical and organisational aspects, but also on institutions. These are important messages for policy makers. On an individual basis, the different systems in the two municipalities seem to affect people's stated attitudes. These differences diminish when they are in a common setting where process and dialogue stimulate new thoughts and encourage people to act more altruistically.  相似文献

In this study, controlled low-strength concrete (CLSC) is mixed using different water-to-binder (W/B) ratios (1.1, 1.3 and 1.5) and various percentages of sand substituted by waste LCD glass sand (0%, 10%, 20% and 30%). The properties of the fresh concrete, including compressive strength, electrical resistivity, ultrasonic pulse velocity, permeability ratio and shrinking of the CLSC, are examined. Results show that increases in amount of waste glass added result in better slump and slump flow, longer initial setting time and smaller unit weight. Compressive strength decreases with increasing W/B ratio and greater amounts of waste glass added. Both electrical resistivity and ultrasonic pulse velocity increase with increases in amount of waste glass and decreases in W/B ratio. On the contrary, the permeability ratio increases with increases in W/B ratio, but decreases with greater amounts of waste glass added. CLSC specimens cured for different durations show little changes in length with shrinkage below 0.025%. Our findings reveal that CLSC mixed using waste LCD glass in place of sand can meet design requirements. Recycling of waste LCD glass not only offers an economical substitute for aggregates, but also an ecological alternative for waste management.  相似文献

All municipal solid waste (MSW) management systems—even “high quality systems” or those employing “best practices”—face multiple challenges, e.g., decreasing prices of secondary raw materials recovered by municipalities, increasing complexity of waste composition, technological lock-ins. Policy-making involves translating these challenges into goals that are generic in nature and implementing them on MSW fractions thanks to tailor-made policy tools, e.g., anticipated disposal fees. Anticipating the impacts of policies can provide valuable insights into the adequacy of policy tools with respect to economic, political, and social contexts of MSW. The goal of this paper is to construct consistent, future scenarios of Swiss waste glass-packaging disposal based on literature and stakeholder knowledge, including the allocation of waste to different disposal routes. These scenarios are future states to which the current system could transit to due to alternative policies in line with waste policy goals and varying societal constraints (e.g., commodity prices). Results of scenario construction show that policy has a limited effect on waste glass-packaging disposal because of economic constraints, preventing goals from consistently being achieved. For instance, increases in energy prices can impede a policy favoring recycling over downcycling to foam glass, an energy-saving product. The procedure applied to construct possible scenarios suits well the ambition of considering uncertain future developments affecting MSW management as it integrates qualitative and quantitative knowledge of various sources and disciplines.  相似文献
