Silica fume for furnace door refractory materials

Silica fume for furnace door refractory materials:This microsilica is generally added to the cement used in the construction of furnace doors in factories.There is no significant difference between the construction method of Silica fume for ceramics refractory and that of ordinary refractory, but good organisation and compactness of vibration are necessary during construction. Silica fume refractory material early performance will make the final set time earlier, should pay attention to the plastering. Silica fume refractory construction safety should be in strict accordance with the relevant construction specifications for refractory engineering operations, but because of the lighter silica fume, it is strictly prohibited to throw the material in the air to prevent silica fume flying. Silica fume should be packed in plastic woven bags with compound film. Product loss of activity in the event of water caking, so it should be stored in a dry, rainy, sun-shaded environment.
