Regeneration method for ceramic slurry generated by removing precision casting ceramic core with alkali erosion method
The invention relates to a regeneration method for ceramic slurry generated by removing a precision casting ceramic core with an alkali erosion method. The regeneration method comprises the following steps: (1) according to the quantity of the ceramic slurry, adding clear water of 1 to 3 times, and performing mechanical stirring, wherein the stirring rotation speed is 60 to 80 turns per minute, and the stirring time is 2 hours; (2) detecting the PH value of slurry stirring solution; if the PH value is greater than or equal to 9, continuously adding clear water and stirring; if the PH value is less than 9, stopping adding clear water and stirring; (3) discharging the slurry stirring solution, heating up a sediment to 900 DEG C for baking, preserving heat for 2 hours under the condition of 900 DEG C, and then naturally cooling; (4) scattering an acidic reagent into the discharged slurry stirring solution in a way of adding while stirring; (5) after adding the acidic reagent, continuously stirring for 1 to 2 hours; (6) standing the stirring solution for 6 to 8 hours. The regeneration method has the beneficial effects that the ceramic slurry generated by removing the precision casting ceramic core with the alkali erosion method is recycled to serve as a refractory matter, cleaning liquid thereof is recycled to serve as clear water or available alkali liquor, and waste is avoided.
