Description
Technical field
The present invention relates to a kind of preparation method of steam-pressing brisk, belong to construction material preparing technical field.
Background technology
Building brick in the past is generally fired brick, and materials are difficult, complex manufacturing and high energy consumption, can be produced in production process
Raw pernicious gas, it is big to the potential pollution of air, clay brick is prohibitted the use of now, while strictly limitation fired brick project, furthermore,
Existing sintering brick process is poor to slurry dewatering effect, and moisture content is still higher after dehydration, and at least 80%, so in brickmaker
During the mixture of skill, mud cake is easily agglomerating, then is equipped with other traditional raw materials, the brick poor-performing being finally made, it is impossible to wide
It is general to be applied to the fields such as materials for wall, municipal works, revetment brick.Steam-pressing brisk is to utilize flyash, cinder, slag, slag, bastard coal
The industrial residues such as stone, mine tailings, residue of chemical industry or natural sand, tidal land mud etc.（The one or several kinds of above raw material）As gathering materials,
Added cement, lime etc. as cementitious matter, be equipped with additive it is compressing after, what is manufactured without high-temperature calcination is a kind of new
Materials for wall.
Existing steam-pressing brisk technology is main using flyash, gypsum or sand as raw material, and traditional steam-pressing brisk can be with according to raw material
It is divided into three series：Fly ash autoclaved brick, gypsum steam-pressing brisk and sand-lime steam-pressing brisk.Continually developing and opening up with flyash purposes
Exhibition, can increasingly go up as the high-quality fly ash price of steam-pressing brisk raw material；It is used as the accessory substance in the fields such as wet desulphurization, gypsum
Dewater treatment is not only needed, and the solubility of the main component calcium sulfate of gypsum is larger, easily causes brick body scum, it is soft that it meets water
The characteristic of change needs to spend very big cost to overcome；Sand as building primary raw material, with the prosperity of building trade, its price
Also high all the way, the cost pressure that autoclaved lime-sand brick manufacturer faces is gradually increased, while these three steam-pressing brisk mechanical strengths
It is poor with anti-pressure ability, the problem of easily cracking when in use, limit it and use scope.Therefore, it is urgent to find a kind of machinery
Intensity is high, and anti-pressure ability is strong, and the steam-pressing brisk of cracking phenomena is less prone in use.
The content of the invention
The technical problems to be solved by the invention are：Poor for traditional steam-pressing brisk mechanical strength, anti-pressure ability is weaker, leads
There is provided a kind of preparation method of steam-pressing brisk for the problem of causing easy cracking phenomenon during using.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
（1）Count by weight, by 800~1000 parts of oil refinery waste water process second pond activated sludge, 200~300 parts of river sands,
100~120 parts of flyash, after 30~40 parts of plant ash are mixed with 3000~5000 parts of water stirrings, through press filtration, washing, ageing, are obtained
It is aged wet feed；
（2）It is soaked in water after straw is cut, obtains the short stalk of preprocessing straw, then by the short stalk of preprocessing straw with being aged wet feed successively
After laying, add water sealing and fermenting, then is centrifuged, and obtains lower sediment thing；
（3）Count by weight, by 60~80 parts of lower sediment things, 10~15 parts of quick limes, 6~8 parts of gypsum, 10~15 parts
Water, mixes rolling, obtains rolling material, then will be pressed into adobe after rolling material injection molding, through autoclave curing and natural curing, produces
Steam-pressing brisk.
Step（1）In described ageing process, can also add oil refinery waste water process second pond activated sludge quality 2~
4 times of biogas slurry.
Step（2）In described successively laying, every layer of laying depth of the short stalk of preprocessing straw is 3~5cm, and ageing wet feed is every
Layer laying depth is 3~5cm, and laying gross thickness is 35~45cm.
Step（2）The described sealing and fermenting time is 25~30 days.
Step（3）Described autoclave curing condition is：It it is 180~200 DEG C in temperature, pressure is in still kettle
8~12h of autoclave curing is carried out under the conditions of 1.3~1.6MPa.
Step（3）The described natural curing time is 28~30 days.
The present invention is compared with other method, and advantageous effects are：
（1）The present invention is first with the microorganism enriched in oil refinery waste water process second pond activated sludge cheap and easy to get and has
Machine matter nutrition, originates by inorganic salts of plant ash, in ageing process, is aided with biogas slurry, makes microorganism in activated sludge and biogas slurry
Activated, and be uniformly distributed in activated sludge, river sand and flyash, during sealed fermenting, the microorganism after activation
Make organic matter degradation in straw, and leave the straw muscle of relative difficult degradation, as the vascular bundle composition in straw stem, straw muscle is equal
It is even to be distributed in adobe, as reinforcement, during autoclave curing, as supporting construction in adobe, improve brick body
Mechanical strength and compression strength, it is to avoid brick body ftractures in use；
（2）The present invention is by the way that during the fermentation, degradable organic matter degradation is small molecule carbohydrate in raw material, is centrifuged
It is in afterwards in sediment, the adhesive property of product can be improved, while after fermented, active group increasing number in raw material makes original
It is more firm that material is combined, and during the fermentation, because of the corrosion function of microorganism, form hole supporting construction, effectively dropping
While low brick body density, the composition such as quick lime and gypsum can be penetrated into effectively inside pore structure, further improve brick body
Mechanical strength.
