Study and Manufacture of Lightweight Heat-insulated and Refractory Flyash Bricks;

Study on a big aperture lightweight aspheric mirror manufacture;

The new multifunction wall composite material with characteristics of light weight and thermal insulation, is composed of light material which is made of foamed plastics of polystyrene based on gypsum , could enhance the surface strength of inorganic and organic coherence and solve the flaw of light material flowing up by adding a surface active reagent N produced by ourselves.

Using casting powder or P-slag, at the standpoint of green and environmental materials and composites of cement matrix, this thesis has researched the subject of "non-autoclave and compound-foamed cement wall-block with light weight".

The effect of raw material, addition, synthesizing temperature, holding time etc on properties of synthetic light weight mullite material was studied.

For improving the capability of floating islands and decreasing the pollution from organic wastes,it is necessary to develop a new type carrier of floating islands,which is light,highperformance and propitious to microbe's adhesion.

Lightweight structure is a new construction system, which based on the research about the structure and the material to make the building lighter and more transparent possible.

An overview of new approaches to deep desulfurization for light oil;

Progress in light oil de-stinking technology;

This paper analyzes the fire character, fire type and extinction methods of light oil outward floating roof tank in general.

After being preheated and fired,dewatered sludge with additives is made into light ceramsite that can be used as filler for sewage purification and for decoration,etc.

On the basis of introducing the study on using sewage sludge from sewage treatment plant as a source to produce a new kind of building material-light ceramsite both at home and abroad,the application prospect of the technology on aspect of preparation technologym,technical feasibility analysis and the economic and environmental profits are discussed.
