Abstract
The present invention relates to energy saving building engineering material field, especially a kind of aerated-block production technology.Specifically using phosphogypsum powder as primary raw material, add land plaster, pulverized limestone, cement, foaming agent, foam stabilizer, water etc., and pass through following steps: stock, ingredient, stirring, casting, hot cell initial set, green body are cut, hot cell it is quiet stop, the aerated-block of the high standard performance that obtained dry density is low, compression strength is high such as microwave steam press maintenance；Wherein, it calculates according to the mass fraction, ardealite fine powder dosage is 350~500 parts, pulverized limestone dosage is 80~150 parts, slag powders dosage is 20~30 parts, cement consumption is 30~40 parts, foaming agent consumption is 0.3~0.5 part, foam stabilizer dosage is 0.04~0.06 part, water consumption is 200~300 parts.The present invention realizes waste utilization, reduces the cost of aerated-block, saves material and consumption, has biggish economic benefit and social benefit.
Description
Technical field
The present invention relates to a kind of production methods of ardealite production aerated-block, belong to energy saving building engineering material field.
Background technique
The solid slag that ardealite generates when referring in phosphoric acid production with sulfuric acid treating phosphorite, main component are sulfuric acid
Calcium, content generally can reach 70~90% or so, and submember contained therein is different and different with the rock phosphate in powder place of production, generally
All phosphate and silicate containing rock composition Ca, Mg.China discharges about 20,000,000 tons of ardealite every year at present, adds up discharge capacity
Nearly hundred million tons, be maximum one kind of discharge capacity in gypsum offscum, and the phosphogypsum slag of discharge occupies a large amount of soils, forms slag mountain, serious dirty
Soil and water resources are contaminated, while restricting enterprise development, become a big environmentally friendly obstacle of enterprise development, the present invention mentions in order to solve the above problem
New thinking has been supplied, has there is good economic benefit and social benefit.
Summary of the invention
For the raw material sources of existing aerated-block, the present invention provides a kind of producer of ardealite production aerated-block
Method.
Technical solution of the present invention, a kind of production method of ardealite production aerated-block, the method steps are as follows:
(1) by water content be 0 ~ 25% ardealite and pulverized limestone, slag powders, cement in mass ratio: 500:150:30:40 carry out
It is sufficiently mixed, is homogenized 1-3 hours；
(2) raw material for taking step (1) to be homogenized carries out stirring with slurry, and foaming agent stirring is added, foam stabilizer is added, reaction temperature is
30 ~ 60 DEG C, casting precuring is carried out, the precuring time is 2 ~ 3h；
(3) step (2) are subjected to steam press maintenance, vacuumizing the 0-- 6Mpa time controlled at 0.5-1 hours；
(4) it is carried out on the basis of step (3) raw pressure (heating), vacuum degree control is controlled in-0.6-1.0 Mpa, time in 1-2
Hour；
(5) on the basis of keeping 1.0 Mpa of vacuum degree, steam press maintenance 6-8 hours；
(6) decompression processing is carried out after the completion of step (5), pressure reduction is controlled at 1-2 hours, is slowly depressured；
(7) product is transported into storage storage.
The present invention is to be produced using enterprise's residue, belongs to environmentally friendly approval using phosphogypsum powder as primary raw material, production cost compared with
It is low, product quality is good, and the environmental protection pressure of enterprise can be mitigated；Have compared with prior art following the utility model has the advantages that with ardealite
For primary raw material, compares with flyash or sand feedstock production process with tradition and significantly reduce production cost.
The present invention plays positive work to the comprehensive utilization of ardealite to handle building gypsum plaster that ardealite is produced as raw material
With meeting the requirement of national standard.
Present invention process process is clearly easily controllable, and application is good, the product of non-hazardous environment, and production environment is friendly.
