T/CNFPIA 3004-2019 Stone Wood Plastic flooring is formally released in 2019, 3 and 20 months, and after the group standard is implemented, in order to promote the application of the stone crystalline flooring in engineering, the China Association for forestry industry and the China society for urban science and research jointly compile and release the technical standards for the application of the Stone Wood Plastic flooring in 2020, 4 months. With the increasing expansion of the market of the stone floor in recent years, the demand of raw materials for the stone floor base material is increased, and especially the consumption of primary resources such as light calcium carbonate and talcum powder is obviously increased.
The stainless steel slag is industrial solid waste which is alkaline, and the main components of the stainless steel slag are CaO and Fe 2 O 3 、SiO 2 And small amount of ZnO, CuO and Cr 2 O 3 Heavy metal oxides such as PbO; the fly ash is different from common fly ash or fly ash, is not a chemical inert substance, contains various harmful heavy metal substances such as Cd, Pb, Zn, Cr and the like and salts which can be leached by water, belongs to dangerous solid waste, and can be used after being treated by a curing technology. The solidified fly ash solves the problem that various harmful heavy metal substances and salts such as Cd, Pb, Zn, Cr and the like can be leached by water, and the main chemical component of the solidified fly ash is SiO 2 、Al 2 O 3 And CaO. At present, the stainless steel slag and the solidified fly ash have low utilization rate and are piled in open air in large quantity, thereby not only occupying valuable land, but also polluting the surrounding environment and underground water. If the stainless steel slag and the solidified fly ash can be used for replacing expensive primary resources of light calcium carbonate and talcum powder, the utilization additional values of the stainless steel slag and the solidified fly ash can be improved, and the production cost of the stone crystal floor base material can be reduced.
