STRIAL REVOLUTION WITH THE CATALYTIC TECHNOLOGY – La rivoluzione industriale con la tecnologia catalitica»
Surface thermal treatments Aft er pre-treatment and coating, both with liquid paint and powder coating, the subsequent process is the paint polymerization, a phase apparently less critical than the previous ones, but fundamental not only for the finishing of the treated component, but also for the ti me, space and energy involved. By means of the catalytic technology of Infragas’ infrared panels the paint polymerization takes a very short ti me: in case of liquid paint, plants equipped with infrared catalytic gas heaters treat in 25 minutes chassis for excavators weighing 1,2 tons and the process of polymerization is completed with a temperature of 115°C on the item. In case of powder coating the complete gelling and subsequent polymerization occurs, for example, in 6 minutes on tanks in the automotive sector. Generally, the treatment ti me that can be obtained with the IR catalytic technology corresponds to less than the half of the necessary ti me in the processes with hot-air traditional systems. Anyway, the ti me reduction is not the only positive aspect.
