They are formed from different mon- esaccharide units through glucosidic bonds, with the advantages of high viscosity, good gel property, environmental-friendly and low cost. In this review, we focus on the progress of the application of seaweed polysaecharides in the fields including food, medicine, tissue engineering and environment engineering, where seaweed polysaccharides are used as food additives, edible coating materials, drug-release materials, medical dressing, tissue scaffolds and environmental adsorption materi- als. Introducing special properties, such as targeting, electrical conductivity and thermasensitivity, and designing bionic controllable micro/nanostructures to fabri- cate and develop multi-functional, intelligent seaweed polysaccharides would be the research hotspot in the future.展开更多

The results show that the formation of silica fibers makes structure of ramming materials dense. During the process of extruding mud and ramming materials, SiC is partly oxidized ; CaO , F% 03 and carbon penetrate towards the outer wall. The improvement of ramming materials can inhibit the penetration of molten slag, iron and carbon. The bulk density of environmental-friendly ramming ma- terials dried at 200 ℃ is 2.90 g · cm-3, the cold com- pressive strength of this kind of ramming materials dried at 200 ℃ is about 17. 0 MPa and fired at I 450 ℃ is about 39. 2 MPa.展开更多
