Description
Technical field
The present invention relates to building material technical field, specifically refer to the processing technology of a kind of environmental protection brick for building.
Background technology
At present, the processing technology of environmental protection brick is day by day ripe, the overwhelming majority is employing CHARACTERISTICS OF TAILINGS SAND, Calx, Gypsum Fibrosum, cement and other additives is primary raw material, add water to be stirred, then the material being stirred is positioned in adobe mould enter thermostatic chamber stand a period of time, again the material after standing is carried out High Temperature High Pressure steam press maintenance, make the environmental protection brick with insulation, fire prevention, lightweight feature.Traditionally formula carries out environmental protection brick production, and for ensureing the stability produced, and the used in amounts of technical parameter requirement, cement and the Calx such as the comprcssive strength of product, dry density reaches the 30% of total dry material.Owing to cement, the expensive average price of Calx reach 420 yuan of left and right per ton, so it is higher to produce the cost of raw material.Owing to CHARACTERISTICS OF TAILINGS SAND material is harder, wearability is better, and the fineness that processing technique requires needs the screen over-size reaching 0.08mm screen cloth below 30%, causes CHARACTERISTICS OF TAILINGS SAND processing power consumption square tail ore in sand form power consumption big, every more than 24 degree, and energy resource consumption is higher.
And in recent years, along with the expansion of the popularization of Concha Ostreae " formula that hangs down cultivation method " technology and the market demand, cultivation scale and the production and processing ability of coastal Concha Ostreae are largely increased, and become coastal Concha Ostreae producing region peasant and increase the important channel of income.But, a large amount of Concha Ostreaes of residual in Concha Ostreae process of manufacture, it does not have be utilized effectively and deal carefully with, severe contamination rural environments, directly affects the improvement of town and country human settlement and new countryside construction.
After chemical examination, find that sea Concha Ostreae can be fabricated to produce the oyster shell powder of required calcium containing compound containing the construction material of more than 90% after calcining.Based on this, research and develop a with the Calx of oyster shell powder replacement part after calcining, the environmental protection brick for building of the expensive building materials raw material such as cement and realize the research purpose that new technology production model prepared by this environmental protection brick for building is the present invention.
Summary of the invention
The present invention furthers investigate on the basis of existing environmental protection brick, and utilizing discarded CHARACTERISTICS OF TAILINGS SAND and oyster shell powder is primary raw material, and in conjunction with exclusive new technology production model, develops honest and clean, more environmental protection lower in cost, the better environmental protection brick for building of performance.
The concrete technical scheme of the present invention is as follows:

(2) Calx is broken into the granule of 1～2 centimeter, and then levigate to 800 orders, screen over-size reaches less than 15%；
(3) CHARACTERISTICS OF TAILINGS SAND, oyster shell powder, Gypsum Fibrosum, cement, Calx are put into agitator tank, agitator tank limit adds the stirring of raw material limit, rotating speed 30～the 60r/min of described agitator tank, adds foaming agent continuously stirred 38-45s again after stirring 3-4min, stirs and agitator tank is heated by steam；
(4) by, after being steam heated to material and reaching 38～42 degree, charging material into mould, it is then fed in the thermostatic chamber of 45～50 DEG C standing 1.5～2 hours so that it is anti-pressure ability reaches more than 0.3MPa and makes adobe；
(5) adobe made is put into steam press maintenance in the constant voltage high-temperature steam still of pressure 1.25～1.4MPa, temperature 190～195 DEG C and within 7.5～8.5 hours, makes this environmental protection brick；
Described mixed grinding is according to technological requirement ratio, CHARACTERISTICS OF TAILINGS SAND, oyster shell powder to be thrown to corresponding feeding equipment, CHARACTERISTICS OF TAILINGS SAND and oyster shell powder by forklift jointly enter ball mill with water after feeding mixes and carry out being sufficiently mixed grinding.
Described material loading mould is made anti-pressure ability through thermostatic chamber standing and is reached more than 0.3MPa adobe, described adobe can be cut by designing requirement by conventional tile cutter device.
Described foaming agent is aluminium powder or aluminium powder cream.
Advantages of the present invention: new technology production model is to mix oyster shell powder in CHARACTERISTICS OF TAILINGS SAND to carry out mixed grinding, in mixed grinding process, the CHARACTERISTICS OF TAILINGS SAND silicon dioxide activity of part is activated and carries out preliminary hydration reaction with the calcium oxide in oyster shell powder, by grinding and hydration reaction, mixed slurry substantially increases chemical property, additionally, the particle suspension of slip also improves, the mortar of better performances can be prepared, make that fineness that CHARACTERISTICS OF TAILINGS SAND early stage processing technique requires is required rises to 60% from the screen over-size of original 0.08mm screen cloth from 30%, reduce the process time to CHARACTERISTICS OF TAILINGS SAND and processing power consumption, save the energy；While ensureing that every technical parameters such as product comprcssive strength, dry density require, reduce cement, Calx incorporation, reduce production cost；And effectively utilize and dealt carefully with Concha Ostreae produced by the cultivation of coastal Concha Ostreae, improve environment.
