Description
Technical field
The present invention relates to building material field, be specifically related to the fire-resistant sintered perforated brick of a kind of Attapulgite shale.
Background technology
Novel wall material mainly refers to take the material of construction that the non-clay resources such as sandstone, shale, industrial solid waste residue, the remaining soil of building are the starting material mechanization production; there is protection soil, protection of the environment, save energy, utilize refuse, gain in strength and the characteristic such as economic and practical; shale brick is compared with clay solid brick; sharpest edges are that its production does not damage arable land and energy consumption is lower, meet national technical development policy.
Shale is by clay, in earth movement, to be pushed and the rock that forms, there is laminated or laminar bedding, impact easy splinter with hard thing, shale does not have viscosity, and plasticity-and water-permeable are all very poor, just can be processed into shale building block after need to pulverizing very carefully by block shale, otherwise dried shale green bricks crackle is many, and can produce explosion in sintering process, fraction defective is higher, has increased production cost.
Mineral Resources in China 80% is intergrowth mineral, and a large amount of valuable resources retain among mine tailing, and tailings impoundment need to take a large amount of soils.A lot of Tailings Dams exceed the time limit or excess load is used, and even violation operation, make Tailings Dam have great potential safety hazard, and people's property and the life security of surrounding area caused to serious threat.
Attapulgite clay, except containing attapulgite, often contains the mineral such as montmorillonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate.
The volcanoclastic rock that also has with the symbiosis of attapulgite clay ore deposit, volcanoclastic rock is mostly on the upper strata in attapulgite clay ore deposit, the thickness of the volcanoclastic rock ore bed on upper strata, some attapulgite clays mining area is up to tens of rice, attapulgite clay is in recovery process, the volcanoclastic rock on upper strata, attapulgite clay mining area is abandoned as waste, investigate factually, the volcanoclastic rock that 1 ton of attapulgite clay of every exploitation produces has more than 30 tons, by the output of producing 150000 tons per year, calculate, the volcanoclastic rock produced is up to 4,500,000 tons, all can be utilized for many years, whole mining area is the volcanoclastic rock mixture of again piling up everywhere, cause the serious wasting of resources and financial loss.
Coal gangue is thrown aside, takies tract, and sulfide in coal gangue is overflowed or leached can atmosphere pollution, farmland and water body, and waste dump also can the spontaneous combustion presence of fire, or, in the avalanche in rainy season, silts river up and cause disaster.
