(续2001年第3期)4发展绿色建材的几点建议近年来,绿色建材在我国得到了大力开发,但与发达国家相比还有很大差距。即使在国内,绿色建材在发达地区与发展中地区之间的开发和应用也不够平衡,在推广应用上还未受到广大消费者的足够重视。就如何发展我国的绿色建材,许多专家学者献言进策,提出了不少建议。在此归纳为以下几个方面:(1)加强宣传,提高认识。由于绿色建材的发展历史还比较短,人们对其认识还不够深刻和全面。因此,要利用各种宣传工具(广播、电视、报纸、书刊等)和各种宣传形式(如学术报告会、技术交流会、信息… 相似文献

6月20日,北京市发改委相关负责人表示,北京市绿色建筑行动实施方案即将印发。继福建、山东、江苏等省之后,北京也将执行建筑节能强制标准,绿色有机保温材料产业由此迎来了发展的新机遇。
4月以来各地连续出台的建筑节能强制标准,是对国家《绿色建筑行动方案》的细化落实。国家住建部科技与产业化服务中心墙材革新与结构技术处处长屈宏乐,在近日举行的2013年全国绿色建材与节能结构技术交流推广大会上表示,《绿色建筑行动方案》要求因地制宜、就地取材,大力发展安全耐久、节能环保、施工便利的绿色建材。加快发展防火隔热性能好的建筑保温体系和材料,多功能复合一体化墙体材料等建材。积极支持绿色建材产业发展,组织开展绿色建材产业化示范。这无疑为绿色建筑、绿色建材行业吹响了大发展的号角。 相似文献

The miscibility of various amorphous polybutadienes with mixed microstructures of 1,4 addition units (cis, 1,4 and trans 1,4) and 1,2 addition units have been investigated. The studies here involved optical transparency, differential scanning calorimetry, and small angle light scattering. It was found that a 90 percent (cis) 1, 4 addition polybutadiene was immiscible with high (91 percent) 1,2 addition polybutadiene. Reduction of the 1,2 content to 71 percent induced an upper critical solution temperature (UCST) with the cis 1,4 polymer. Polybutadienes with 50 percent and 10 percent 1,2 contents were miscible above the crystalline melting temperature of the cis 1,4 polybutadiene. Immiscibility of the 91 percent 1,2 addition polymer was also found with a 10 percent 1,2 polybutadiene. The latter polymer also exhibits an UCST with the 71 percent 1,2 polymer. The results are used to interpret the characteristics of blends of polybutadienes of varying microstructure. 相似文献

The objective of the study was to explore the effect of the degree of deacetylation (DD) of the chitosan used on the degradation rate and rate constant during ultrasonic degradation. Chitin was extracted from red shrimp process waste. Four different DD chitosans were prepared from chitin by alkali deacetylation. Those chitosans were degraded by ultrasonic radiation to different molecular weights. Changes of the molecular weight were determined by light scattering, and data of molecular weight changes were used to calculate the degradation rate and rate constant. The results were as follows: The molecular weight of chitosans decreased with an increasing ultrasonication time. The curves of the molecular weight versus the ultrasonication time were broken at 1‐h treatment. The degradation rate and rate constant of sonolysis decreased with an increasing ultrasonication time. This may be because the chances of being attacked by the cavitation energy increased with an increasing molecular weight species and may be because smaller molecular weight species have shorter relaxation times and, thus, can alleviate the sonication stress easier. However, the degradation rate and rate constant of sonolysis increased with an increasing DD of the chitosan used. This may be because the flexibilitier molecules of higher DD chitosans are more susceptible to the shear force of elongation flow generated by the cavitation field or due to the bond energy difference of acetamido and β‐1,4‐glucoside linkage or hydrogen bonds. Breakage of the β‐1,4‐glucoside linkage will result in lower molecular weight and an increasing reaction rate and rate constant. © 2003 Wiley Periodicals, Inc.
