一种RH浸渍管及其内衬层和内衬层的粘结剂
摘要：
本发明公开了一种RH浸渍管及其内衬层和内衬层的粘结剂，其中，所述粘结剂由酚醛树脂与镁砂细粉混合均匀得到。所述镁砂细粉的粒径为180～250目。所述酚醛树脂的固含量为50～65％。所述酚醛树脂与镁砂细粉的重量比为60∶40～75∶25。RH浸渍管内衬层采用所述的粘结剂粘结镁尖晶石质内衬砖制成。本发明提供的粘结剂，既能够保证组装RH浸渍管用镁尖晶石质内衬砖时具有足够的强度，同时能够方便内衬砖的更换。
摘要（英）：

The invention discloses an RH immersion tube and a liner layer and a liner layer adhesive thereof, wherein the adhesive is prepared by uniformly mixing phenolic resin and fine magnesia powder. The grain size of the fine magnesia powder is 180 to 250 meshes. The solid content of the phenolic resin is 50 to 65 percent. The weight ratio of the phenolic resin to the fine magnesia powder is 60:40 to 75:25. The liner layer of the RH immersion tube is produced by adopting the adhesive to stick magnesia spinel liner bricks. The adhesive provided by the invention not only can ensure that the magnesia spinel liner bricks for assembling the RH immersion tube have enough strength, but also can facilitate the replacement of the liner bricks.
