Description
Technical field
The present invention relates to building material field, and in particular to a kind of method that artificial stone is produced using discarded slurry.
Background technology
Artificial stone typically refers to artificial solid material, artificial stone quartz, artificial stone hilllock stone etc., be one kind by natural stone
Material mine tailing rubble powder and novel green building and ornament materials made of the mixture of specific bonding material, due to its production process
Meet the standard of energy-conservation, emission reduction and low-carbon, and substantial amounts of industrial tailings and rubbish can be digested, application has a extensive future.
Compared to traditional construction materials such as stainless steel, ceramics, artificial stone is not only vdiverse in function, various colors, and application is also more extensive.It is artificial
Stone is non-toxic, radioactivity, fire-retardant, not viscous oil, not permeable dirt, antibacterial and mouldproof, easily wear-resisting, impact resistance, maintenance, seamless spliced, moulding
It is changeable.
In the process such as stone material, terrazzo, artificial stone, the mixing of more discarded slurry, i.e. water and mortar can be produced
Thing.Due to a large amount of productions of such product, caused mud typically using settling, filtering, dry, makes mud complete dried powder
Handled again, this process will use equipment, electric energy, press filtration, drying to be unfavorable for promoting, it is necessary to certain flow, cost is larger
Using.If can will by plain sedimentation mud be applied to artificial stone production in, then can produce larger economic interests with
And there are wide market prospects.
The content of the invention
It is an object of the invention to provide a kind of method that artificial stone is produced using discarded slurry can effectively reduce production
Cost, while reasonable mixture ratio between each raw material, artificial stone is prepared by method involved in the present invention and is respectively provided with not
