Method for repairing corundum-mullite push plate and repairing binding material
The invention discloses a method for repairing a corundum-mullite push plate and a repairing binding material, and is characterized in that the repairing method comprises the steps of uniformly mixing 15-25wt% of 200-mesh andalusite fine powder, 20-35wt% of 325-mesh tabular corundum fine powder, 30-45wt% of alumina micro powder and 5-10wt% of silicon oxide micro powder serving as repairing raw materials with a solvent consisting of water-soluble resin, water and aluminum dihydrogen phosphate, and preparing a pasty repairing bonding material; and smearing the repair bonding material on the to-be-repaired fracture surface of the corundum-mullite push plate, and applying pressure to enable the parts on the two sides of the fracture surface to be bonded and fixed, wherein the corundum-mullite push plate can be put into use after being dried for 4 h at the temperature of 120-150 DEG C, after the corundum-mullite push plate is normally used once in a push plate kiln, the repair bonding material reacts and is sintered, and repair is completed.
本发明公开的是一种修复刚玉‑莫来石推板的方法及修复粘结料，其特征在于所述修复方法为，15～25wt％200目红柱石细粉,20～35wt％325目板状刚玉细粉,30～45wt％氧化铝微粉，5～10wt％氧化硅微粉为修复原料，与水溶性树脂、水、磷酸二氢铝组成的溶剂均匀混合,制成膏状的修复粘接料；将修复粘接料涂抹在刚玉—莫来石推板待修复的断面处,施加压力使断面两边的部分粘结固定,经120℃～150℃烘干4h即可投入使用，在推板窑内正常使用一次后，修复粘结料发生反应烧结,即完成修复。
