建材用相变工质材料渗出程度评价方法的研究

将相变复合材料用于建材可使建筑增加自调温功能，实现建筑节能。研究复合材料中相变工质材料渗出规律，提出检测渗出的新方法——扩散-渗出圈法，为相变复合材料用于建材提供了实验依据。     

自调温功能材料

相变调温技术用于建筑材料可使建筑增加自调温功能，实现建筑节能，按无机，有机分类方法分别介绍有望用于建材自调温功能开发的相变工质材料，以及浸渍法，混合法，高聚物交联吸收法，微胶囊法等可用于相变工质材料包覆的几种方法，并对自调温工质材料和包覆技术的发展趋势进行了展望。     

Microstructure of sepiolite and its adsorbing properties to dodecanol

The acid treatment process, testing methods, microstrcture of sepiolite mineral materials and their adsorbing properties to dodecanol were studied respectively. The results show that by acid treatment to raw sepiolite thinner fibre clusters and single fibres turn up, the pore volume and the number of micropore and mesopore in sepiolite all increase, and adsorbing properties of modified sepiolite to dodecanol are improved significantly. In the combined materials of dodecanol and sepiolite prepared under the best condition, the proportion ofdodecanol is 67.96%, and then it is much higher than the result calculated from traditional BET method.     

Influence of Composite Phosphate Inorganic Antibacterial Materials Containing Rare Earth on Activated Water Property of Ceramics

Antibacterial ceramic was prepared by doping enamel slurry with composite phosphate inorganic antibacterial materials containing rare earth (inorganic antibacterial additives), and then the mechanisms for activating water and improving seed germinative property were tested by nuclear magnetic resonance (NMR) and the method of testing oxygen dissolved in activated water. Results show that the half peak width of ^17O-NMR for tap water activated by the antibacterial ceramic drops from 115.36 to 99.15Hz, and oxygen concentrations of activated water increase by 20%, germinate rate of horsebean and earthnut seeds increases by 12.5% and 7.5%, respectively. Therefore antibacterial ceramic doped enamel slurry with inorganic antibacterial additives containing rare earth can reduce the volume of clusters of water molecules, improve activation of tap water, and promote plant seeds germinate.
