Description
Technical field
The present invention relates to the especially ardealite comprehensive utilization of resources of assembled building materials industry and industry by-product gypsum and two
Mortar is built in field more particularly to a kind of spray of fire-retardant type thermal insulation sound-insulation wall.
Background technology
Building block self-supporting wall, traditional self-supporting wall -- masonry (brick mix structure) are made of being built by laying bricks or stones by block and mortar
Wall or column, including brick setting, block masonry, barnacle body and wallboard masonry, in general engineering construction, masonry accounts for whole building
About the 1/2 of object dead weight, the amount of labour used and cost about respectively account for 1/3, are the important materials of architectural engineering.For a long time, China accounts for leading
Status building material sintering bore cob brick have two thousand years history, with clay tile and be known as " Qin brick and Han tile ".But it is this
Building material needs a large amount of clays to make raw material, and to be effectively protected arable land, national requirements does not have to clay brick as possible.
Masonry structure is the exclusive architecture of traditional self-supporting wall, the disadvantage is that：
1, compared with armored concrete, the intensity of masonry is relatively low, and the sectional dimension of component is larger, and material utilization amount is more, dead weight
Greatly.
2, masonry builds substantially manual mode by laying bricks or stones, and the construction amount of labour is big.
3, the tension of masonry, bending resistance, shearing strength are all very low, thus antidetonation is poor, destroy heavier when by earthquake, make
It uses and is subject to certain restrictions, be simply possible to use in earthquake intensity≤6 degree area below.
4, clay brick need to be manufactured with clay, occupied farmland and destroyed arable land, influence agricultural production.
5, rural area self-built housing is not easy far from down town, building material acquisition, and valence is high and speed of application is slow.
Plank self-supporting wall
It is assembled by planks such as prefabricated large-scale inside and outside wall board, floor and roof boardings, also known as large panel building.It is industry
Change the main Types of total-prefabricated construction in building.Plank building can mitigate construction weight, raise labour productivity, and expand
The usable floor area and shake-proof ability built greatly.The lining of plank building is mostly the solid slab or cored slab of armored concrete；Outside
Wallboard is mostly the armored concrete composite plate with insulating layer, it is also possible to lightweight aggregate concrete, foam concrete or macropore coagulation
The wallboard with exterior finish is made in soil etc..The critical issue of large panel building is design of node.It should ensure that component connects in structure
Globality (connection method between plank mainly has welding, be bolted and rear pouring concrete integrated connection).In waterproof structure
The problems such as thermal technology of the waterproof and building seam, corner of making Side fascia seam to be properly settled is handled.The main of large panel building lacks
Putting is：
1, there is larger restriction to architectural modeling and layout；
2, dimension precision requirement is high, bad adaptability；
3, transport difficult, transportation cost are high；
4, the flat cost height enterprise of fabrication and installation.
Industry by-product gypsum
The year yield of China's industry by-product gypsum is about 1.84 hundred million tons, wherein 70,000,000 tons of ardealite, desulfurated plaster
7550 tons, 38,080,000 tons of other industry by-product gypsums, (about 70%), ardealite utilization rate other than desulfurated plaster utilization rate is higher
Less than 20%, total comprehensive utilization ratio is only 48.1%.
Ardealite is the industry byproduct of wet-method process phosphoric acid, often produces 1t phosphoric acid and 5t ardealites are about discharged, at present
Chinese phosphatic fertilizer company discharges about 70,000,000 t/a of ardealite every year, and it is more than 300,000,000 t to add up volume of cargo in storage, and most ardealites are taken as
Waste abandons.
Phosphogypsum slag one is to occupy a large amount of soils；Second is that stockyard investment is big, operating charges are high, the volume and ground of cinder field are stacked
Base Anti-seeping technology requires stringent；Third, wasting valuable Sulphur ressource；Fourth, the acidity contained and easy pair of other harmful substances
Surrounding enviroment pollute, and the provinces such as Sichuan, Yunnan, Guizhou, Hubei especially concentrated to phosphorus chemical industry cause long-term dirt
Dye；The environmental condition of waste residue safe handling has become the restraining factors for building phosphate fertilizer plant's selection factory site, and then it is multiple to directly affect phosphorus
Fertile industrial expansion.
As it can be seen that otherwise the stage that ardealite has arrived disposition energetically will directly affect people, environment and society
Harmony and territory protection, and bring immeasurable loss directly to the survival and development of enterprise.Especially from 2018 1
From month 1 day, country will impose 25 yuan/ton of solid waste environment protection tax to blowdown enterprise, certainly will be brought more to business operation
Big pressure！
