Hazard analysis and use of fly ash

Fly ash from coal combustion flue gas after the catch in the closing down of fine ash, coal-fired power plant fly ash is discharged from the main solid waste. Our main thermal power plant fly ash oxide composition: SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. Fly ash is one of the larger of China's current emissions of industrial waste, with the development of the power industry, fly ash emissions from coal-fired power plants every year. A lot of fly ash not addressed, it will generate dust, pollution of the atmosphere; into the water if the river will cause blockage of toxic chemicals which can also cause harm to humans and creatures.

Our country is the largest producer of plastic products, each year about 2.5 million tons of waste plastics need to be addressed. The main raw material used in the project was recycled plastics and fly ash. Intends to develop environmentally friendly products for outdoor products, such as building templates, handrails, guardrails, doors, window frames, flooring, outdoor chairs, flower boxes, trash, and its products are completely discarded the old Lee, turning waste into treasure, do not consume limited resources environmentally friendly products. After the product is still one hundred percent recycled waste. The project for the protection of forest resources and reduce the growing problem of "white pollution" has major social and economic significance.

Fly meet both plastic and wood material performance, with excellent moisture resistance, drilling, and rivet performance, better structural rigidity and better appearance and feel, improved resistance to crushing performance, quality, uniformity and environmental friendliness have been significantly improved mechanical properties and excellent overall physical appearance of products, can replace wood and the production of chemicals and plastics for injection molding, low production cost, high yield; say from a technical level, it is equipped with its own, such as plastics, many advantages of wood, metal and other materials, wood can; may be able to plastic, aluminum can on behalf of, a wide range of applications, from analysis of market demand applications that can scale applications in the following areas:

1.Building materials: includes a substrate, wall materials, templates, flooring and decorative wood series.

2.Outdoor facilities include: fencing, decking, columns, handrails and other major products. 

3.Logistics and transport: the main box, container board, all kinds of trays, etc.

4.Transport facilities: for example fences, partitions, wall, signs, skids, etc.

5.Household items: such as wardrobes, cabinets, tables, chairs, coffee table, flower, and so on.

project advantages 

1.The only access to specialized extrusion equipment Fly invention patents, with the authority of the program and the success of the fly ash in the case of building applications.

2.Select multiple items: do outdoor decoration materials, wall panels, ceiling, gallery frame, fences, etc.; also be interior decoration materials, high-strength composite flooring, wall panel, wall panels; furniture or office furniture, plates, etc.; also can be used as building materials, such as building templates, rod, etc.

3.Can be supported by a full set of technology, can produce the complex requirements of the products and may provide application materials to the enterprise in order to obtain financial support from local and NDRC subsidies.

4.Add the proportion of ash in the products from the 10% -60% can be achieved. And to a variety of composite materials and PVC / PP / PE / ABS / PMMA, etc.
