Description
Technical field
The present invention relates to technical field of nano material, be specifically related to a kind of nano-calcium carbonate activation method.
Background technology
Wet-process modified is carry out activation treatment to calcium carbonate in ripe slurry solution after carbonization enrichment, utilize calcium carbonate dispersion in the liquid phase more much easier than dispersion in the gas phase, if add dispersion agent, the better feature of dispersion effect, make the effect of calcium carbonate granule and activator molecule evenly.Calcium carbonate granule is after wet-process modified process, and its surface energy reduces, even if form offspring after press filtration, drying, only forms more weak soft-agglomerated of bonding force, efficiently avoid the hard aggregation phenomenon caused because of the generation of chemical bond oxo bridge in dry method modification.To be CN101525146A patent name be publication number " a kind of preparation method of modified nano calcium carbonate " discloses preparation process and be: " 1. in calcium carbonate quality, be reconfigured as the suspension that concentration is 10% ~ 20% after the nano calcium carbonate suspension prepared being filtered; 2. under whipped state, the pH value of suspension, at 70 DEG C ~ 80 DEG C, controls between 6.5 ~ 7.2 by the temperature controlling nano calcium carbonate suspension, drips activator solution, the amount adding activator is 3% ~ 6% of nano-calcium carbonate quality, stirs and is incubated 50 ~ 60 minutes; 3. by the product filtered while hot after above-mentioned process, dry and modified nano calcium carbonate product can be obtained after grinding." wet-process modified there is good coated effect, but ripe for nano-calcium carbonate slurry must be heated to 80 DEG C of activation effects later reaching more satisfactory by wet-process activation usually, and production cost is higher.
Summary of the invention
The technical problem to be solved in the present invention how to make normal temperature wet-process activation arrive more satisfactory activation effect, significantly can reduce again the energy consumption cost of activation.A kind of nano-calcium carbonate activation method of the present invention, in order to solve the problems of the technologies described above, is achieved through the following technical solutions.
A kind of nano-calcium carbonate activation method, step one, obtains calcium oxide by limestone calcination, by calcium oxide and hot water in one to five ratio carry out digestion reaction, then the milk of lime of gained is slightly starched to filter to refine and obtains refined lime breast;
Step 2, the normal temperature refined lime of mass concentration 10-15% breast is carried out abundant carburizing reagent with carbonic acid gas, control the temperature of carbonation reaction within the scope of 25-40 degree by temperature regulating device, and add the crystalline form directed agents of the 0.3-0.5% of calcium carbonate quality, the obtained ripe slurry of nano-calcium carbonate.
Step 3, above-mentioned nano-calcium carbonate slurry is added in surface treatment reaction still, stir speed (S.S.) is that 150-300 turns/min, add the stearic acid dehydrated alcohol of 50 DEG C or palmitinic acid chloroform or stearic acid and palmitinic acid dehydrated alcohol saturated solution as activator, the amount of activator is 1% ~ 2% of nano-calcium carbonate dry powder quality, continues to stir 30min; Then polyacrylamide amine salt is added as dispersion agent, the amount of polyacrylamide amine salt is the nano-calcium carbonate dry powder quality of 0.5% ~ 0.8%, continue to stir 10min, slurries leave standstill 2h, finally adopt vacuum filtration, 105 DEG C of freeze-day with constant temperature 2 ~ 3h, sieve through 200 orders after pulverizing mill grinds, finally obtain normal temperature modified nano-calcium carbonate calcium product.
Crystalline form directed agents is sulfuric acid or inorganic salt.
Compared with activating with traditional intensification, there is following advantage:
1. traditional intensification reactivation process usually adopts and passes into low-pressure steam heating nano-calcium carbonate slurries, and product per ton heats up to activate probably to be needed to consume steam 0.1t, and with steam per ton 200 yuan calculating, the energy consumption cost of light intensification heating is that product per ton reaches 20 yuan.Whole normal temperature activation, reduces the loss of energy, meets the requirement of low-carbon environment-friendly, amphitypy society, Sustainable development.
2. owing to not needing to arrange the heating units such as boiler and equipment, simplify Production Flow Chart, reduce cost of investment and production cost.
