Procedure for Application of Zircoat to Chimneys & Ducts

6 to 12mm thick Zircoat coating prevents steel sections from the attacks of the hot corrosive gases escaping upwards. Zircoat effectively acts as a barrier against corrosive gases and absorbs chemical attacks. The coating procedure is given as under:

	Weld 6mm dia x 25mm long steel studs to the inside steel chimney wall at around 300mm centres.
	Apply 6mm thick Zircoat on the inside section of the chimneys and fix with a steel chicken wire mesh to the bolts.
	Heat up the Zircoat coated chimney cylinder at 200°C temperature for around 20 hours.
	After heating, apply final coat of 2 to 3mm thick Zircoat on the laid out wire mesh to level the coated area and to totally cover the wire mesh and steel studs. Dry up the Zircoat coated area thoroughly.

Zircoat

Zircoat is of great advantage to high and low temperature tunnel and shuttle kilns. It considerably extends service life of kiln cars and kiln combustion areas.

1 to 2mm thick Zircoat coating on the heating area increases its service life by 4-5 folds as compared to the uncoated ones, and also saves on fuel energy by preventing heat energy losses due to leakage through the lining cracks.

Zircoat should be applied on clean surfaces only. Old refractory surfaces must be thoroughly cleaned with a scraper or wire brush, removing all loose pieces and particles. Any glossy surface should be thoroughly roughened with an abrasive disc. Cracks and holes should be cleaned and then filled with a thick Zircoat paste.
