Abstract
The present invention provides a kind of method for preparing cement retarder with industry by-product gypsum, and the raw material for preparing cement retarder includes following constituent: titanium gypsum 20 ~ 50%, ardealite 10 ~ 40%, sulphur gypsum 10 ~ 30%, manganese gypsum 5 ~ 10%.The preparation of cement retarder is carried out by using the by-product gypsum generated in industrial production, it consumes by-product gypsum and carries out product manufacturing, and then solve the problems, such as that disorderly row leaves about chemical company's industrial residue, avoid pollution environment, by the industrial waste recycling and reusing of chemical enterprise emission, it solves the problems, such as that enterprise faces, while obtaining certain economic value.
Description
Technical field
The present invention relates to cement retarder preparation field more particularly to a kind of cement retarder is prepared with industry by-product gypsum
Method.
Background technique
The substance of the solid waste sulfur acid calcium discharged in the industrial production is referred to as industrial gypsum, industry by-product gypsum
Ardealite including titanium gypsum, manganese gypsum, citric acid gypsum, boron gypsum and bunt gypsum etc..Under the requirement of environmental protection, how
The industry by-product gypsum for effectively handling bulk deposition has become an extremely urgent problem in China or even world wide.
Current stacking processing method seriously restricts the development of enterprise, has both occupied a large amount of soil, polluted underground water and has left
Huge security risk, and the stacking expense for needing corporate payments high, are unfavorable for the sustainable development of enterprise.
Summary of the invention
In view of the above-mentioned problems of the prior art, preparing water with industry by-product gypsum the object of the present invention is to provide a kind of
The method of mud retarder carries out the preparation of cement retarder by using the by-product gypsum generated in industrial production, consumes by-product
Gypsum carries out product manufacturing, and then solves the problems, such as that disorderly row leaves about chemical company's industrial residue, avoids pollution environment.
The present invention provides a kind of method for preparing cement retarder with industry by-product gypsum, the cement retarder for preparing
Raw material includes following constituent: titanium gypsum 20 ~ 50%, ardealite 10 ~ 40%, sulphur gypsum 10 ~ 30%, manganese gypsum 5 ~ 10%.
Further improvement lies in that: the preparation step is as follows:
Step 1: titanium gypsum, ardealite, sulphur gypsum and manganese gypsum are taken out in proportion spare；
Step 2: it is put into after above-mentioned raw materials are mixed in mechanical device and carries out extrusion forming；
Step 3: primary drying is carried out to the material of extrusion forming；
Step 4: redrying is carried out to the material after primary drying；
Step 5: by the crushing material after drying at powdered, cement retarder is obtained.
Further improvement lies in that: the manganese gypsum content is within the 10% of the total weight of titanium gypsum and ardealite.
Further improvement lies in that: when preparing cement retarder, when ardealite is excessively high containing sour component, stone is added into material
Ash is acid in material to reduce.
The beneficial effects of the present invention are: carrying out the system of cement retarder by using the by-product gypsum generated in industrial production
Standby, consumption by-product gypsum carries out product manufacturing, and then solves the problems, such as that disorderly row leaves about chemical company's industrial residue, avoids pollution ring
The industrial waste recycling and reusing of chemical enterprise emission is solved the problems, such as that enterprise faces by border, while obtaining certain economy
Value.
