1) Can be applied on steel plates and concrete lining materials;
2) High acid resistance and aging resistance;
3) High temperature resistance
It can withstand high temperatures above 200°C continuously and 220°C for a short time. It can operate under high temperature and high and low temperature alternation for a long time, expand and contract with temperature changes, and maintain good elasticity. Suitable for dry-wet alternation and high and low temperature changes.
4) High bonding strength
Under standard conditions, the bonding strength is greater than 1.3MPa, and under acid and water immersion conditions, the bonding strength is greater than 0.9MPa.
5) Low dosage
The coating thickness and gap width are controlled within 2.5-3.0mm.
6) Good elasticity
When the flue gas is forced to pass through the desulfurization tower and enter the chimney, it will not be damaged during the violent reheating process and the sudden temperature change caused by air preheating failure.
