HYBRID: Optimized Sol-Gel Technology.
Advantages of hybrid castables compared with conventional cement containing castables:
Faster heating up with shorter downtimes
Cost and energy-saving
Very good adherence on existing refractory materials
Installation possible on hot surfaces and with high ambient temperatures
Higher application temperature limits
Optimized thermomechanical behaviour
Long storage life of 12 months
Increased cold crushing strength and modulus of rupture as well as optimized abrasion resistance in the temperature range below 1000 °C.
REFRAJET® Addmix: An innovative injection system
The injection system creates a reactive aerosol that is injected centrally into the continuous flow of dry gunning mix material. A liquid binder can be added to the pre-wetted dry material via a conventional nozzle system at the end of the deliver hose.
Pre-wetting of the dry gunning mix offers several advantages, such as reduced dust generation at the gunning nozzle, less material rebound – particularly during overhead work – plus enhanced bonding to refractory surfaces.
The process has been optimized for cement-free shotcretes of the REFRAJET® Nanobond type, but it can also be used for many other concretes from Refratechnik's product range.
