REFRAJET® Addmix:
An innovative injection system.

Injection: Intelligent, innovative

We have developed this innovative injection system specifically for our REFRAJET® Nanobond dry-gunning concretes. ­REFRAJET® Addmix reduces material rebound as well as dust generation at the injection nozzle.

As a result, you can count on improved mechanical properties and reduced porosity.

The material

• The dry material has a practically unlimited storage life and requires no special marking, as it is manufactured without chemical additives or binders.
• Bonding strength and layer thickness on refractory surfaces can be adjusted and varied without any problems.
• Product properties are significantly improved:
  • onding on worn refractory surfaces is greatly improved.
  • Pre-wetting the concrete results in a denser concrete ­struture with reduced porosity.
  • Compared with the standard procedure, cold crushing strength and cold modulus of rupture can be increased ­significantly.

Processing

• Pre-wetting by means of a centrally injected aerosol greatly reduces the risk of hose blockages
• Dust generation is also reduced noticeably – particularly ­during overhead work
• Material rebound is also reduced clearly
• Fine particle activation is more intense than with the standard procedure
• The gunning operator is not hampered additionally: He simply works as accustomed with his standard equipment, because the injection parameters are adjusted by the injection machine operator via the system‘s control unit.

The REFRAJET® Addmix nozzle

• The nozzle can be used with practically every conventional rotor injection machine
• All parts of the REFRAJET® Addmix nozzle are easy to replace
• The injection of other liquids or powders is possible
• In order to reduce dust gene-ration and material rebound, ­REFRAJET® Addmix can also be used with hydraulically bonding refractory concretes
