Description
Technical field
The invention belongs to the field of building materials, and in particular to a kind of mill preparation method of inorganic interior maintenance powder body material.
Background technique
Alkaline residue is ammonia-soda process soda ash and the waste residue generated.China is currently maximum soda manufacture state in the world, often
The alkaline residue that year generates because producing soda ash is up to 3,000,000 tons, and so a large amount of alkaline residue causes many problem of environmental pollutions.But alkali
Slag chloride ion content is high, and the mass of ion score under absolute dry condition can reach 10%, so that the secondary use of alkaline residue is difficult
It is heavy.Alkaline residue utilization rate in China's only has 3~4% at present, and main processing ways are stockpiling or fill out extra large processing, brings to environment
The problems such as such as " white sea " phenomenon.
The self-constriction of concrete is always the problem of cement-based gelling material is difficult to avoid that.Especially high performance concrete water
Gray scale is low, and self-constriction is larger, it is easier to generate crack, influence structure durability.It is to solve the problems, such as this using interior conserving material
Effective way.It is super absorbent resin (SAP) that internal curing material of high-performance concrete, which is studied more, at present.Research both at home and abroad
The shrinkage phenomenon of concrete is mainly reduced by the subsequent interior maintenance released water and realize concrete by the high-hydroscopicity of SAP.But
There are the higher problems of price by SAP.Meanwhile SAP has water swellability, thus exist and be spiked into concrete after release moisture
Atrophy causes concrete voids rate big, and then the problem of influence intensity.China is wideling popularize high performance concrete at present, anxious
It inexpensive need to can solve the problems, such as the technology of the self-desiccation shrinkage of high performance concrete.
By researching and analysing to alkaline residue microstructure, find there is large quantity micropore gap in alkaline residue, therefore consider alkaline residue
After dechlorination, the interior conserving material as high performance concrete.
Applicant proposes powder processed after alkaline residue dechlorinates early period, is added in high performance concrete when using as interior curing agent
Thinking.The method for preparing powder include with mixing material intergrinding, revolution oven drying method, the methods of spray drying process, but with
There are active principles to be diluted for mixing material intergrinding, influences using effect, there are powder granules for revolution oven drying method relatively slightly, spray
The problems such as mist seasoning is high there are energy consumption.It is badly in need of developing curing agent preparation method in new alkaline residue.
Summary of the invention
The technical problems to be solved by the present invention are: while keeping dechlorination alkaline residue internal pore structure as far as possible, by it
It is prepared into inorganic interior maintenance powder body material, realization is turned waste into wealth.In order to solve the above-mentioned technical problem, it is an object of the invention to mention
For a kind of mill preparation method of inorganic interior maintenance powder body material.
To achieve the goals above, the technical solution adopted by the present invention is as follows.
A kind of mill preparation method of inorganic interior maintenance powder body material, includes the following steps:

The broken filter cake of chlor-alkali slag；
(2) powder processed of the dechlorination broken filter cake of alkaline residue
The broken filter cake of alkaline residue that will dechlorinate is dried, and obtains the dry dechlorination broken filter cake of alkaline residue；By the broken filter cake of dry dechlorination alkaline residue
It is added in mill flour mill, is handled through grinding, obtain the powder that granule content of the partial size greater than 0.080mm is less than 10wt%, obtain
To the inorganic interior maintenance powder body material.
Preferably, mill flour mill described in step (2) includes charging gear, milling machine host, cyclone separator, receipts
Dirt device and centrifugal blower are, it can be achieved that the continuous milling of automation.
It is furthermore preferred that mill flour mill described in step (2) be enclosed construction, made by centrifugal blower be inside it
Negative pressure avoids dust from leaking.
It is furthermore preferred that the milling machine host includes more than two concatenated mills.
It is further preferred that the process of the processing of grinding described in step (2) are as follows: powder passes through the milling of mill flour mill
Enter cyclone separator after machine host, coarse granule is again introduced into milling machine host grinding, and fine grained enters dust-precipitator and obtains qualification
Powder.
Compared with the prior art, the invention has the following advantages and beneficial effects:
(1) the mill powder-making technique of food processing field is applied to construction material preparation field by the present invention, is preparing powder
During internal conserving material, the pore structure inside dechlorination alkaline residue can be retained to the greatest extent, without in addition adding mixing
The alkaline residue that dechlorinates can be prepared into the inorganic interior maintenance fine powder that can be used for concrete, solved using traditional ball by material
The problems such as slimeball brought by the milling equipments such as grinding machine.
(2) present invention carries out the separation of thickness powder using cyclone separator, and the powder granule of preparation is uniform, and fineness is thinner,
Performance is stablized.Mill powder and strength stage division are combined and carry out powder separation, there is the porous structure of powder to destroy less, powder
