Product description:
Fiber spraying furnace lining is a kind of ceramic fiber application technology developed on the basis of traditional ceramic fiber application technology and drawing on the refractory powder and particle spraying process. The ceramic fiber is treated by special spraying equipment, and the treated fiber is sent to the nozzle with high pressure air, and then sprayed on the working face after evenly mixing with the mist binder sprayed from the nozzle around the nozzle. Forming ceramic fiber sprayed wall lining.
The factors affecting the performance and effect of the ceramic fiber spray coating are: the content of ceramic fiber slag ball, the length of fiber, the uniformity of the fiber surface covering binder, the structure of the anchor, the sprayed surface treatment and other factors.
