1. The polyvinyl alcohol (PVA) powder is fully dissolved in deionized water and filtered. You can choose between PVA-1788 or 2488, depending on your preference.

2. Place the PVA adhesive into a stainless steel reactor (an enamel reactor could also work, though its heat transfer isn't as effective). Add the emulsifier OP-10 and mix thoroughly using the mixer.

3. Pour 15% of the total volume of polyvinyl acetate monomer (which equals 6.9 units) and 40% of the potassium persulfate mixture (0.036 units) into the stainless steel reactor. Continue stirring while gradually increasing the temperature. Once it reaches 60-65°C, stop heating. Note that potassium persulfate should first be mixed with distilled water to create an 8%-10% aqueous solution, which should be added in small increments.

4. Even though heating has been stopped, the temperature will rise due to the initiator. When it exceeds 65°C, the reactor's reflux device will begin to circulate. When the temperature surpasses 80°C, the reflux will slow down. At this point, start dripping the polyvinyl acetate monomer from the reactor’s drop tank, ensuring the drip rate is approximately 10% of the total volume per hour (around 4.6 units). Monitor the reaction temperature closely and use cooling water to regulate the temperature inside the reactor jacket, keeping it under 80°C.

5. While dripping the vinyl acetate monomer, you should also drip the initiator, adding about 4.5% of the total formula amount per hour.

6. The addition of vinyl acetate and the initiator should be completed within approximately 8 hours. Owing to the initiator, the reaction will become quite vigorous. Once all the monomers are added, the temperature will naturally rise. When it reaches around 93°C, maintain this temperature for 30 minutes, indicating the polymerization process is nearly complete.

7. Turn on the cooling water to reduce the temperature in the stainless steel reactor. Once it drops below 50°C, add a sodium bicarbonate solution (dissolved in advance at 10% concentration) and dibutyl phthalate to adjust the pH to 6-7.

8. The mixer in the stainless steel reactor must remain operational throughout the entire process. Once cooled to room temperature, the final white latex product is obtained. Stop the mixing, discharge, and packaging procedures.

9. If the white latex product has too high viscosity and poor water resistance, you can slightly reduce the amount of polyvinyl alcohol in the formulation.

10. If the white latex emulsion shows poor stability, you might consider reducing the amount of certain initiators in the formulation. However, too little initiator can hinder the polymerization of the monomers.

11. The amount of dibutyl phthalate should not exceed 10% of the monomer. Excessive amounts can lead to decreased adhesion in the final product and increased costs. Its primary function is to enhance the emulsion's toughness and reduce its film-forming temperature.

12. If the white latex product contains excessive foam, add an appropriate amount of defoamer.

13. The timing and quantity of potassium persulfate initiator are crucial. If the reflux rate is high when the reflux starts, it suggests the initiator is not working effectively. In such cases, stop adding monomers and add the initiator to the monomer once the reflux is stable.

14. The white latex produced by the above formulation and method results in a white, uniform emulsion liquid with a solid content of about 50% and a pH of approximately 5.

In addition, the white latex product can also be modified by adding 801 glue and anatase titanium dioxide to create a modified white latex.
