Alternatively, the titanium extraction slag, the alkali activator and the auxiliary agent can all be in a dry state.
Wherein, moisture absorption should be avoided during stirring and mixing.
Optionally, after moisture absorption, the titanium extraction slag reacts with the excitant, so that agglomeration and denaturation are caused, and the service performance of the product is affected, so that moisture absorption and wetting should be avoided before the whole stirring and product sealing moisture-proof packaging.
In the exemplary embodiment, 6-30 parts by mass of the alkali activator and 1-10 parts by mass of the auxiliary agent are stirred and mixed uniformly for 1-6 hours, 70-100 parts of the titanium extraction slag are added, and the stirring and mixing are continued for 1-6 hours.
