最近,由徐州特种耐火材料厂研制出一种新型修补炉墙用的高温粘结剂,可以用来快速修补锅炉炉膛的耐火层。当炉膛内出现炉墙断裂、炉拱塌落或门孔及燃烧器周围的耐火砖、耐火塑料损坏时,在停炉后即可用此粘结剂进行镶补、嵌补。使用时,先将损坏部位灰尘清理干净,铲除周围松动部分,再将脱落下的旧砖按损坏部分的大小,配以同样尺寸的砖块,在接合部位表面涂上一层粘结剂后镶嵌在上面;同样也可用碎耐火砖块与粘结剂拌成混凝土进行填洞、堵缝。修好经压实抹平即可点火,点火时虽经
Recently, Xuzhou Special Refractory Factory developed a new high temperature binder for furnace wall repair, which can be used to quickly repair the refractory layer of the boiler hearth. When the furnace wall rupture occurs, the collapse of the furnace arch or door hole and the firebrick around the burner, fire-resistant plastic damage, after the shutdown furnace can be used to make up the adhesive, embedded. When used, first clean the damaged parts of the dust, erase the surrounding loose parts, and then fall off the old brick according to the size of the damaged parts, accompanied by the same size of the brick, the bonding site surface coated with a layer of adhesive after inlaid In the above; the same can also be broken fire bricks and concrete mix binder for filling holes, caulking. Repair and compaction can be ignited, although the ignition
