Description

Artificial jade and manufacture method thereof based on building waste

Technical field

The invention belongs to the artwork production field, is to be the artificial jade and the manufacture method thereof of raw material production with the building waste specifically.

Background technology

Building waste is the general name of the various solid waste that produce in building construction process of people, according to statistics, at present the quantity of China's building waste has accounted for about the 30-40% of municipal wastes total amount, and according to the tempo of real estate in recent years, still can maintain sustained and rapid growth every year later on.People generally adopt the mode of air storage or landfill to handle building waste at present, and this has taken a large amount of soils on the one hand, and on the other hand, the dust that produces in transportation and stacking process etc. has caused the serious environmental pollution again, influences the appearance of the city and environmental health.

For many years, people have adopted multiple technologies that building waste is fully utilized, as wherein steel scrap muscle, iron wire, metal parts etc. are sorted, reclaim, perhaps waste material grinding and processing such as brick, stone, concrete are become various building material products, but these technology all belong to extensive low value-added utilization, economic benefit is lower, is easy to cause loss, and this also is that present people are to not high major cause of building waste comprehensive utilization enthusiasm.

For these reasons, new technology, the novel process of high value added utilization carried out in active demand in the market to building waste.The contriver of this patent promptly is engaged in the development work of artificial jade from April, 2009, has developed multiple products such as artificial white jade, black jade, jasper, carbuncle, and excellent property has broad application prospects at jewellery and artwork field.
