Description
Technical field
The invention belongs to construction timber field, particularly relate to a kind of gangue spontaneous combustion brick and preparation technology thereof.
Background technology
Clay brick; have another name called fired brick; very important effect is played at conventional building field; but in response to " energy-saving and emission-reduction " of country and " protection soil " call; the improved process of various fired bricks occurs; finding the system of various part or all of replacement clay to change a job skill, wherein the trade waste such as gangue, flyash, slag powders, slag is the direction generally studied now.But roasting again, roasting need a point different temperatures section to carry out after existing most gangue or flyash technique need maintenance, display, owing to preparing the difference of tile floor point, in a lot of regions, limited by local resources condition, do not allow in brick, add the carbon containing industrial waste gas things such as enough gangues, flyash, make adobe still need to additional coal in roasting process to be fired, again produce atmosphere pollution, it is impossible to the call of totally linearization country " energy-saving and emission-reduction ".Secondly, these conventional trade wastes add the molding effect being easy to affect brick in brick-making raw material to.
Summary of the invention
The invention discloses a kind of novel gangue spontaneous combustion brick and preparation technology thereof, it is intended to overcome deficiency of the prior art, reduce clay consumption, add residual Folium Camelliae sinensis, increase and remove moisture to New Buildings, the effect of anti-mosquito, the kind of abundant spontaneous combustion brick building brick, improves the quality of spontaneous combustion brick.
The technical scheme is that a kind of gangue spontaneous combustion brick, it is made up of the raw material of subordinate's weight proportion, gangue 40-65, flyash 2-30, shale 1-20, clay 1-10, water 10-30, residual Folium Camelliae sinensis 0.05-5, foaming agent 0.01-1, exciting agent 0.05-10.The content of MgO of gangue is high, have influence on the molding of adobe, clay, the interpolation of flyash can reduce the content of MgO in adobe, exciting agent can activate the early activity of flyash, the interpolation of foaming agent can improve conventional clay from the present situation such as great, porosity is low, foaming agent selects flexibly according to the difference of the concrete proportioning of raw material, conventional have CCW-95 type solid blowing agent and AB composite foamable agent, foaming agent and exciting agent use the more preferable mixing additionally aiding gangue, clay, flyash, shale, residual Folium Camelliae sinensis simultaneously；Additionally, residual Folium Camelliae sinensis is as domestic refuse, there is dedusting, protection against the tide, the effect of anophelifuge fly, add to first in brick-making raw material, make gangue spontaneous combustion transform as having preferable dedusting, protection against the tide, the function brick of anophelifuge fly effect.
As a kind of preferred implementation, the water content of described clay is 9%-18%.
As a kind of preferred implementation, described foaming agent is CCW-95 type solid blowing agent or AB composite foamable agent.
As a kind of preferred implementation, described exciting agent is FJ type exciting agent.
The preparation technology of above-mentioned gangue spontaneous combustion brick, it is characterised in that comprise the steps:
(1) gangue, clay, shale, flyash are smashed respectively wear into granule, granularity is less than 2mm, after hot-water soak 8-12 hour of 80 DEG C-100 DEG C of residual Folium Camelliae sinensis 30-50 times, steam 0.5-1 hour with steamer again, foaming agent and exciting agent are dissolved with the water accounting for both gross weights 20-70 times；
(2) gangue of granule, clay, shale, flyash will be worn into, mix homogeneously with the residual Folium Camelliae sinensis after steaming, be sequentially added into and be dissolved with the water of foaming agent and exciting agent, the water steeping residual Folium Camelliae sinensis and remaining water, make compound；
(3) using vacuum extruder that compound is made adobe, through the equipment of Automatic Code base by brick code to sintering briquette kiln car, advance in tunnel cave, utilize the residual carbon internal combustion in adobe, roasting obtains finished bricks；
As a kind of preferred implementation, the roasting of described adobe is carried out under the conditions of 800-1000 DEG C.
As a kind of preferred implementation, the vacuum degree control of described adobe is in the range of 0.6-1.0MPa.
Foaming agent in raw material and exciting agent are removed, uses the finished bricks obtained by finished bricks that above-mentioned same process obtains and the present invention to compare and obtain: the finished bricks forming of the present invention, the finished bricks gravity energy reduction 3-10% of same volume.
The coal gangue baked brick that this technique prepares without displaying, complete spontaneous combustion, green brick forming good, the deadweight of finished bricks reduces, and porosity increases, and has protection against the tide, the effect of anophelifuge fly concurrently, has broad application prospects.
