Description
Technical field
The present invention relates to building material technical field, is more particularly a kind of waste glass powder ultraviolet-resisting polyethylene Side fascia and production method thereof.
Background technology
At present, the mode of vitrified bond during most of brickmaking, is adopted to prepare, but along with the increase of clay produced quantity, clay resource is day by day deficient, not only increase cost of winning, also ecotope is caused to having a strong impact on simultaneously, therefore need badly and optimize and improve existing brick-making method to change the status quo.
Using sodium hydroxide decomposing zircon sand, is the main production that China produces basic zirconium chloride and zirconium dioxide now.China's basic zirconium chloride yearly capacity in 2007 has reached 150,000 t, occupies the first in the world.Demand as the zirconium dioxide of functional materials and structured material also constantly increases, and its production technique cost is lower, but shortcoming is to produce a large amount of wastes (often produce 1t zirconium dioxide product and about discharge sig water 5m3, acid white residue 1t).In recent years, along with production-scale expansion, the process problem of the waste produced in production process also becomes increasingly conspicuous.
Therefore, utilize waste-material-preparing Side fascia be turn waste into wealth, the effective measure of protection of the environment, farmland saving, there is good social and economic benefits.
