Production device for refractory material adhesive silica sol

[0007] Example 1:

[0008] Production raw materials and dosage

[0009] Sodium silicate

[0010] The production equipment of refractory adhesive silica sol mainly includes: storage tank (F101), raw material pump (J101), filter (L101), transfer pump (J102, J103), cation exchange resin filter (L102), anion Exchange resin filter (L103), growth tank (D101), product pump (J104), among them, the storage tank (F101) is used to store sodium silicate aqueous solution, among which, the raw material pump (J101) and the storage tank (F101), The filter (L101) is connected, and the delivery pump (J103) is connected to the anion exchange resin filter (L103) and the growth tank (D101) respectively. The storage tank (F101) has a full volume of 2.7m 3 , Raw material pump (J101) outlet diameter 210mm, transfer pump (J102) impeller diameter 150mm.

[0011] The production device of refractory adhesive silica sol, the production process is: filter the sodium silicate in F101 through L101, and pass the clear solution through the L102 cation exchange resin column to make the Na in the sodium silicate + With H on the cation exchange resin + Perform exchange, adjust the pH of the effluent to 2.1, then pass the L103 anion exchange resin layer to remove the anions in the sol, adjust the pH of the effluent to 3.7, add a quantitative stabilizer to the D101 mother liquor preparation kettle, and continuously add dilute under stirring Silica sol, control the pH to 8.3. Heat to 50°C, control the crystal growth rate to make the particles grow, and finally get the finished product.
