作者 张伟 黄建林 《华东纸业》 2015年第1期37-39,共3页
研究了生物胶乳取代一定比例的丁苯胶乳在铜版纸面涂涂料中的应用。分析了其对涂料指标及涂布铜版纸成纸指标的影响。结果显示:生物胶乳能部分替代丁苯胶乳在铜版纸面涂涂料中使用,且生物胶的使用能改善涂料保水性能;但随着生物胶乳替... 研究了生物胶乳取代一定比例的丁苯胶乳在铜版纸面涂涂料中的应用。分析了其对涂料指标及涂布铜版纸成纸指标的影响。结果显示:生物胶乳能部分替代丁苯胶乳在铜版纸面涂涂料中使用,且生物胶的使用能改善涂料保水性能;但随着生物胶乳替代丁苯胶乳比例的增大,涂料的黏度有所升高,当生物胶乳替代40%丁苯胶乳时,涂料黏度较高,不适合上机使用;同时随着生物胶乳替代丁苯胶乳比例的增大,涂布铜版纸成纸的IGT表面强度、RI湿拉毛强度、印刷花斑性能等主要指标基本上呈逐渐下降的趋势。在保证涂布纸主要指标的前提下,生物胶乳最多能替代30%的丁苯胶乳。 展开更多

This paper presents an experimental study on the behaviour of rendering mortars used to rehabilitate buildings subjected to rising damp and consequently affected by efflorescence. This study was initiated by the characterization, "in situ" and in laboratory, of rendering mortar used as walls coating of an old building affected by efflorescence. Temperature, superficial humidity, mortar water content and salts content were used as characterization tests. Taking into account the reconstitution of old building rendering mortar composition, four different proportions were proposed to simulate different mortars skeletons and porosities. The mortars binders were composed by cement and three additions, such as hydrated lime, artificial hydraulic lime and quicklime paste. The results of capillary water absorption, soluble salts content and permeability test on masonry panels allowed analyzing the performance of mortars compared to the susceptibility of water rise and formation of salts. From this analysis, it was possible to draw some practical recommendations for design coating repair mortar in buildings subject to the problem of rising damp. 展开更多

Both the academic society and the industry are hunting for new energy forms for the future.However,the world should not forget the conventional technologies that contribute to the sustainable society by technical innovations.Among them,lubrication plays a significant role in energy saving and in low CO2emission by increasing the fuel efficiency and by prolonging the service life of machines.With the advance of novel synthetic approaches,and nanoscience and technologies,novel lubrication oils and additives and their formulations are being developed to reduce friction and wear,and novel surface treatment routes and surface coatings are invented and provide more efficient lubrication.These technologies create tremendous chances for machines to work more efficiently with low energy consumption.Here we review the recent progresses and challenges associated with some novel lubrication techniques that include novel surface treatment(such as texturing,high-performance nanocomposite coatings,adapting coating),tribology design(solid and liquid lubrication),energy-conserving engine oil and novel lubricants and formula(such as ionic liquids,low S,P content additives)which are to be adopted to enhance the fuel efficiency to achieve energy saving and low carbon emission.There is increased demand to replace fossil lubricants by degradable green lubricants.Specially designed coatings can reduce drag significantly during navigation of both airplanes and ships.All these aspects will be also reviewed in the paper. 展开更多
