Abstract
The invention discloses a green and environment-friendly brick for building and a new technology production mode for preparation of the green and environment-friendly brick for building, and the green and environment-friendly brick for building uses calcined oyster shell powder to replace part of expensive building raw materials such as lime, cement and the like. Compressive strength and dry density and other technical parameter requirements of a product are ensured, meanwhile mixing amounts of the cement and the lime are reduced, the production cost is reduced, the oyster shell powder is mixed for mixed grinding with tailing sand to prepare good-performance mortar, so that a tailing sand early-stage processing technology requires that the fineness needs to increase from 0.08 mm-sieve screen residue weight of 30% to 60%, the tailing sand processing time and processing power consumption are reduced, the energy is saved, oyster shell produced by coastal oyster breeding is effectively used and duly processed, and the environment is improved.
Description
Technical field
The present invention relates to building material technical field, specifically refer to a kind of environmental protection brick for building and manufacture craft thereof.
Background technology
At present, the manufacture craft of environmental protection brick is day by day ripe, the overwhelming majority is that employing CHARACTERISTICS OF TAILINGS SAND, lime, gypsum, cement and other admixtures are main raw material, adding water stirs, then the material being stirred is positioned in adobe mould and enters standing for some time of thermostatic chamber, again the material after standing is carried out to High Temperature High Pressure steam press maintenance, make there is insulation, the environmental protection brick of fire prevention, lightweight feature.According to conventional formulation, carry out environmental protection brick production, the stability of producing for guaranteeing, and the technical parameter requirement such as the ultimate compression strength of product, dry density, the used in amounts of cement and lime reaches 30% of total dry material.Because cement, the expensive average price of lime reach 420 yuan of left and right per ton, so production material cost is higher.Because CHARACTERISTICS OF TAILINGS SAND material is harder, wear resistance is better, and the screen over-size that the fineness that complete processing requires need reach 0.08mm screen cloth is below 30%, and more than causing large, the every square tail ore in sand form of CHARACTERISTICS OF TAILINGS SAND processing current consumption power consumption 24 degree, energy consumption is higher.
And in recent years, along with oyster " formula that hangs down cultivation method " popularization of technology and the expansion of the market requirement, cultivation scale and the process for processing ability of coastal oyster are largely increased, become the important channel that coastal oyster producing region peasant increases income.But residual a large amount of oyster shellss in oyster process of manufacture, are not utilized effectively and deal carefully with, severe contamination rural area environment, has directly affected town and country human settlements' improvement and new countryside construction.
After chemical examination, find that extra large oyster shells can be made into the oyster shell powder that the material of construction containing more than 90% is produced required calcium containing compound after calcining.Based on this, researching and developing the environmental protection brick for building of the expensive building materials raw materials such as a lime, cement that replaces part with the oyster shell powder after calcining and realizing novel process production model prepared by this environmental protection brick for building is research purpose of the present invention.
Summary of the invention
The present invention furthers investigate on the basis of existing environmental protection brick, utilizes discarded CHARACTERISTICS OF TAILINGS SAND and oyster shell powder for main raw material, and in conjunction with exclusive novel process production model, develops that cost is cheaper, more environmental protection, the better environmental protection brick for building of performance.
Concrete technical scheme of the present invention is as follows:
A kind of environmental protection brick for building and manufacture craft thereof, described a kind of environmental protection brick for building comprises material and water, the ratio of described material and water is 1:0.45～0.6, and described material is by being that raw material by the configuration of following ratio is by weight prepared from by described manufacture craft:

Described fabrication processing is as follows:
(1) CHARACTERISTICS OF TAILINGS SAND adds the water of 35%～45% weight after mixing with oyster shell powder, carries out mixed grinding, and levigate to 800 orders, screen over-size reaches below 30%;
(2) lime is broken into the particle of 1～2 centimeter, and then levigate to 800 orders, screen over-size reaches below 15%;
(3) CHARACTERISTICS OF TAILINGS SAND, oyster shell powder, gypsum, cement, lime are put into stirred pot, stirred pot limit adds raw material limit and stirs, rotating speed 30～the 60R/min of described stirred pot, adds whipping agent to continue to stir 38-45S again after stirring 3-4min, while stir, stirred pot is passed through to steam heating;
(4) by being steam heated to material, reach after 38～42 degree, pack material into mould, then send in the thermostatic chamber of 45～50 ℃ standing 1.5～2 hours, make its anti-pressure ability reach 0.3Mpa and make above adobe;
(5) the constant voltage high-temperature steam still steam press maintenance of the adobe of making being put into 190～195 ℃ of pressure 1.25～1.4Mpa, temperature is made this environmental protection brick for 7.5～8.5 hours;
Described mixed grinding is CHARACTERISTICS OF TAILINGS SAND, oyster shell powder to be thrown in to corresponding feeding equipment according to processing requirement ratio by forklift, and CHARACTERISTICS OF TAILINGS SAND and oyster shell powder jointly enter ball mill with water and carry out mixed grinding fully after feeding mixes.
Described material packs mould into and reaches the above adobe of 0.3Mpa through the standing anti-pressure ability of making of thermostatic chamber, can by design requirements, described adobe be cut by conventional tile cutter device.
Described whipping agent is aluminium powder or aluminium powder cream.
Advantage of the present invention: novel process 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 has improved chemical property greatly, in addition, the particle suspension of slip also improves, can make the mortar of better performances, make the required screen over-size from original 0.08mm screen cloth of fineness of CHARACTERISTICS OF TAILINGS SAND complete processing in early stage requirement rise to 60% from 30%, reduced the process period of CHARACTERISTICS OF TAILINGS SAND and processing current consumption, save energy, when guaranteeing that every technical parameter such as product ultimate compression strength, dry density requires, reduced cement, lime incorporation, reduce production costs, and the oyster shells that the cultivation that effectively utilizes and dealt carefully with coastal oyster produces, improves environment.
