What factors may cause fire retardant agglomeration during material melting?

The agglomeration of fire retardants during material melting is a phenomenon of concern. The occurrence of agglomeration may reduce the fire retardant effect and even negatively affect the performance of the material. So, what factors may cause fire retardants to agglomerate?

If the fire retardant particles are too large, they will not be easily dispersed evenly in the molten material and will be more likely to form agglomerates. Therefore, when selecting a fire retardant, we need to pay attention to its particle size distribution and try to choose a fire retardant with moderate particle size and even distribution.

Melting temperature and time also affect fire retardant dispersion. If the melting temperature is too high, the fire retardant particles may attract each other due to changes in surface energy, resulting in agglomeration. Likewise, melting for too long may also give the fire retardant particles enough time to collide and combine with each other, increasing the likelihood of agglomeration.

The viscosity and fluidity of the material are also factors that need to be considered. Materials with higher viscosity are more difficult to disperse the fire retardant particles evenly in the molten state, while poor fluidity may hinder the movement of the fire retardant particles in the material, leading to agglomeration. occurrence of phenomena.

If stirring is insufficient or uneven, the fire retardant particles may not be effectively dispersed in the material and agglomerates may form. Therefore, during the melting process, we need to use appropriate stirring and mixing methods to ensure that the fire retardant can be evenly dispersed in the material.
