Refractory plastic, also known as refractory castable or refractory repair compound, is a repair and repair material used in high temperature environments. The following are some requirements for the use of refractory plastics:
1. Temperature adaptability: The refractory plastic should be selected to match the temperature range of the repaired area or equipment. Different types of refractory plastics have different temperature resistance characteristics, so appropriate products must be selected according to specific requirements.
2. Application surface preparation: Before using refractory plastic, the repair surface must be fully cleaned and prepared. It is often necessary to thoroughly remove old refractory material, loose particulate matter and dirt, and ensure that the surface is dry and clean so that the refractory plastic can adhere well and perform its repair function.
3. Mixing and application: According to the instructions provided by the manufacturer of the refractory plastic, mix the powder and liquid components of the plastic in proportion until a uniform mixture is obtained. The mixture is then quickly applied to the area to be repaired and shaped and compacted using appropriate tools (eg scrapers, presses, etc.).
4. Curing and drying: Refractory plastics need a certain amount of time to cure and dry. After construction is complete, allow an appropriate curing and drying time according to the manufacturer's recommendations, before ensuring the repaired area is fully restored to normal use.
5. Environmental and safety precautions: When using refractory plastics, relevant environmental and safety requirements should be complied with. This may include using appropriate personal protective equipment (e.g. gloves, glasses, masks, etc.), ensuring a well-ventilated workplace, and properly handling and disposing of any waste or residue.
6. Quality Control: Use standard refractory plastics and make sure to follow the manufacturer's guidelines and recommendations for product use to ensure the best repair results and performance.
The above are the requirements for the use of general refractory plastics, but the specific conditions may vary according to the material type and specific application. Therefore, before using refractory plastic, it is recommended to carefully read and follow the detailed instructions and operating instructions provided by the manufacturer.
