Refractory plastic refers to a refractory material that can be shaped like plastic. It is usually composed of high-temperature curing resin, refractory aggregate and some special additives. According to the different main raw materials and uses of refractory plastics, the types of refractory plastics will be introduced below.
1. Aluminum silicate can be plastic
Aluminum silicate plastic uses alumina, silica, etc. as the main aggregates, uses organic glue or inorganic glue as the adhesive, and adds an appropriate amount of regulators and protective agents. It is suitable for furnace inner chamber walls, partitions, and kiln Repair and reinforcement of the head, kiln tail and other parts.
2. Aluminum phosphate can be plastic
Aluminum phosphate plastic uses kaolin, alumina and tricalcium phosphate as the main raw materials. It is prepared into a slurry through proportioning and then mixed with appropriate gelling and hardening agents. It is cured at a higher temperature and is suitable for various electric power applications. , petrochemical and metallurgical equipment maintenance and installation.
3. Alumina can be plastic
Alumina plastic uses alumina and other oxides, silica and kaolin as the main raw materials, uses organic glue or inorganic glue as the adhesive, and adds an appropriate amount of additives and protective agents. It is suitable for various rotary drum kilns, Fire-resistant structural parts in high-temperature pipelines and petrochemical industries.
4. Silicon carbide can be plastic
Silicon carbide plastic uses silicon carbide as the main material, adding binders, expansion agents, steel fibers, etc., and is suitable for high-temperature furnaces, wear-resistant equipment, metallurgical equipment, ceramic equipment and other fields.
In addition to the common ones mentioned above, there are also some special-purpose refractory plastics, such as silicon nitride plastics, boron carbide plastics, etc. Different types can be selected according to different uses.
