れている。Highly reinforcing carboxy resin has a small particle size and high adsorption properties, so in order to uniformly disperse and mix carboxy resin and resin in one layer, strong mixing force such as a vacuum cleaner is required. A large mixer is required, and the power required for mixing is also very large. This mixing is done in a batch method, so
Productivity is low and expensive mixers are used, resulting in increased equipment strikes for the mixing process. For this reason, the mixing time for one cycle of the mixing process is shortened, the amount of processing per unit time is increased, equipment costs are reduced, and the power cost required for mixing is reduced, making it possible to reduce the manufacturing cost of rubber composition acids. There is hope that it can be reduced.
