I would appreciate your advice regarding the particle size variation issue with PBL3000
Thread Content
The factory where I work produces ABS resin. After polymerizing butadiene, it is then agglomerated using the acetate method to produce latex with a particle size of 3000; the process requires that this value be within the range of 3000–3200 nanometers, with 3100 being the ideal value. However, the issue of particle size fluctuations has not been resolved and is difficult to control. I would like to ask: what is the mechanism by which adding acetic acid increases the particle size? I only know that this step is not a chemical reaction; it is the further aggregation of micelles, which results in an increase in particle size.
It is essentially based on the principle of agglomeration: acetic acid is used to balance the charges, thereby balancing the repulsive forces between the emulsifiers and allowing the molecules to get closer to each other; the mutual attraction between molecules then leads to an increase in particle size.
