Solids suspension

This study refers to the preparation of APP/Diatomite (DIA) composite flame-retardant fillers. The materials were prepared by two methods: by adding diatomie powder to the mixture during the preparation of APP or by adding diatomite powder to the suspension of very fine solid APP particals in water.

The primary objective of this research is to study the effect of solids concentration and active particle mass fraction on mass transfer in a solid-liquid (dissolution) system and determine the optimum solids volume fraction and operating conditions that will help to achieve higher mass transfer efficiency at higher solids concentration than hitherto used (> 5% v/v).

Some common practical questions and suggested answers During the development of coating formulae and processes, common problems tend to recur. This section brings together a collection of typical queries and provides suggested solutions. 1. Question: What major process and formulation parameters do I need to take into account in the change from organic solvent coating to aqueous coating? Answer: Looking first of all at the formulation-based parameters, there is a need to increase the solids loading of the coating suspension to something like 12 %w/w if using a typical HPMC-based formula.
