Plastic storable masses are essential materials in refractory applications due to their convenient storage and handling characteristics. They can be shaped without a casting formwork which makes them ideal for custom applications and repairs.
Plastic mixes frequently contain a phosphate source like mono aluminium phosphate solution as a binder instead of water. This enhances the refractoriness under load, gives good abrasion resistance, higher slag resistance and better adherence to spent refractories.
One of the issues with phosphate bonded plastic refractories is their limited shelf life of around three (3) months. We present a newly developed phosphate binder, which increases the shelf life for plastic mixes significantly.
This study compares the plasticity over time and analyses the typical physical properties like density and cold crushing strength at different ranges of temperature.
