Abstract
The invention discloses a nuclear-radiation-resistant coal ash building block. The nuclear radiation-resistant coal ash building block comprises various normal materials of the coal ash building block and 2.8%-3.0% (in percentage by weight) of nuclear radiation-resistant mineral powder is further added, wherein the nuclear radiation-resistant mineral powder is one or more of barite concentrate powder, borax mineral powder and celestite concentrate powder. The nuclear radiation-resistant coal ash building block is prepared by mainly using waste resources including coal ash, slag, sand and the like as the materials, adding nuclear radiation-resistant mineral powder, foaming, curing, steam-curing and cutting. Moreover, the nuclear radiation-resistant coal ash building block has the advantages of being small in volume weight, excellent in thermal-insulation effect, heat-insulating effect, energy-saving effect and soundproof effect, good in machinability, convenient construction and nuclear radiation resistance, and is a novel nuclear radiation-resistant energy-saving wall material.
Description
Technical field
The present invention relates to the material of construction of atomic reactor, i.e. the fly ash building block of a kind of anti-nuclear radiation and production method thereof.
Background technology
The energy in the world mainly relies on oil at present, coal and Sweet natural gas, these underground resources are limited, along with people exploit on a large scale, resource reduces day by day, some places are close to exhaustion, atomic utilization causes the attention of countries in the world gradually, the use atomic energy electric energy that sends of the country that has has accounted for the bigger ratio of whole electric energy, but the key equipment of nuclear power generation is that atomic reactor is usually because earthquake, tsunami, the human operational error waits a variety of causes generation nuclear radiation accident, cause serious pollution for the environment of atomic reactor periphery, thus atomic reactor need in a large number can the shielded nucleus radiation shielding material; The processing of some nuke rubbish of producing of atomic reactor also needs a large amount of shielding materials in addition.Shielding material is the material for the various rays that produce of decay reactor core.In the radiation that reactor produces, what harm was maximum is the big neutron of penetration power and gamma-rays, the shielding material gamma-rays of must can decaying, and make the fast neutron deceleration and be absorbed.Pollute for the nuclear radiation that prevents atomic reactor, usually build very thick concrete at the exterior wall of atomic reactor, do time-consuming taking a lot of work like this, and radiation-resistant effect neither be fine.In recent years, it is found that the nuclear radiation of some mineral pair atomic reactor has good shielding effect, producing the material of construction with shielding effect is to work as forward swing in the developmental big problem of nuclear industry.
Summary of the invention
In order to prevent the nuclear radiation of atomic reactor, the present invention proposes to build fly ash building block and the production method thereof of a kind of anti-nuclear radiation of atomic reactor exterior wall.
The fly ash building block of this anti-nuclear radiation, the raw-material weight prescription comprises the starting material of the fly ash building block of various routines, it is characterized in that, also is added with anti-nuclear radiation breeze, radioprotective breeze part by weight is 2.8-3.0%.
The fly ash building block of this anti-nuclear radiation, raw-material weight prescription: flyash content ratio 70%, every cubic metre of consumption: 350kg; Lime content ratio 13.5%, every cubic metre of consumption: 140-150kg; Cement content ratio 13.5%, every cubic metre of consumption: 25-30kg; The aluminium powder trace, every cubic metre of consumption: 0.4kg, anti-nuclear radiation breeze part by weight is 2.96%.
Anti-nuclear radiation breeze is the barite fine ore of barium sulfate-containing 90%, and its particle diameter is 300 orders.
Anti-nuclear radiation breeze is made up of barite fine ore and borax breeze, and its formulation by weight is, 5 parts of the barite fine ores of barium sulfate-containing 90%, and 2 parts of the borax breezes of boronic acid containing sodium 90%,
Anti-nuclear radiation breeze is made up of barite fine ore, borax breeze and celestite concentrate powder, its formulation by weight is 5 parts of the barite fine ores of barium sulfate-containing 90%, 2 parts of the borax breezes of boronic acid containing sodium 90%, 1 part in the celestite concentrate powder of Han Liu Suan Strontium 90%, above-mentioned three kinds of raw materials are ground to 300 orders.
The production method of the fly ash building block of this anti-nuclear radiation: flyash is added the water mill form slurry, add powdered lime, an amount of cement, aluminium powder and anti-nuclear radiation breeze, after stirring, inject framed in, behind the quiet oxygen foamed solidification, cut into all size building block or sheet material, sent in the autoclave by steam-cured car, namely form the aerated concrete products of porous light under the maintenance of high temperature saturated vapo(u)r, wherein thinner anti-nuclear radiation breeze surrounds fly ash grain, and nuclear radiation has been carried out effectively stopping.
Fly ash building block mainly utilizes waste resources such as flyash, slag, sand to be starting material, add anti-nuclear radiation breeze, produce through foamed solidification, steam-cured cutting, has unit weight little (can bubble through the water column), insulation, heat insulation, energy-conservation, advantages such as soundproof effect is good, workability good, be convenient to construction, anti-nuclear radiation, be a kind of novel anti-nuclear radiation energy-saving wall material, the anti-nuclear radiation of heat-insulation and heat-preservation is the advantage of its maximum, has the wide prospect of promoting the use of.
