Grinding and Classifying Systems for powder coating manufacturers tell you that powder coatings have a tendency to agglomerate at a certain temperature, which is mainly caused by the softening of materials such as resins and leveling agents in powder coatings when heated. So how to avoid powder coating agglomeration at work?

Grinding and Classifying Systems for powder coating manufacturers tell you that first, when producing polyester resins, use some alcohols or acids that can increase the glass transition temperature, or reduce the amount of alcohols that can lower the glass transition temperature of the resins to improve the performance of polyester resins. glass transition temperature.
Reduce the use of low glass transition temperature polymers, such as leveling agents and long face agents, in powder coating formulation planning to ensure that the glass transition temperature of the powder coating system does not drop.
In terms of production, the broken pieces from the steel belt should be fully cooled before entering the grinding process. Install air-conditioning to control the grinding temperature. However, if the pulverized flakes cannot be cooled down before grinding, the latter method will not have a very good effect, and the method of forced cooling of the pulverized flakes can be considered for low temperature treatment.
Grinding and Classifying Systems for powder coating manufacturers tell you that you can add anti-caking additives, such as nano-silica or nano-alumina micropowder to avoid adhesion between powder particles. Anti-caking agents are generally milled at the same time as the broken flakes. Powder works well.
