Refractory mud is a special adhesive used to repair and connect refractory materials, and is often used in the repair and maintenance of furnaces, heat treatment equipment and other high-temperature devices. The following is a detailed introduction to the correct use of refractory mud:

1. Surface preparation

Before using refractory mortar, it is necessary to ensure that the surface being repaired or joined is clean, dry and free of impurities. Tools such as a brush or air gun can be used to clean the surface and remove any dirt, grease or old mud.

2. Moisture regulation

According to the instructions of the refractory mud, add an appropriate amount of water into the refractory mud and stir slowly until a uniform slurry is formed. Be careful not to add too much water to avoid excessive dilution and affect the bonding performance of the refractory mortar.

3. Construction method

Using tools such as scrapers, spatulas or gloves, apply the adjusted refractory putty evenly on the surface to be repaired or joined. Can be filled, leveled or shaped as desired. Make sure the mortar is in full contact with the surface and there are no visible gaps or voids.

4. Ensure curing time

Follow the specified curing times, depending on the type and thickness of the refractory putty. During the curing period, try to avoid any pressure or external force on the repaired part to ensure that the refractory putty can fully set and firm.

5. Baking and drying

After the construction is completed, according to the requirements of the refractory mud, the baking and drying process is carried out at an appropriate temperature. This helps to improve the temperature resistance and stability of the refractory putty. Follow the manufacturer's baking and drying directions to ensure best results.

6. Maintenance and maintenance

Once the refractory putty is fully cured and dry, the condition of the refractory putty should be checked and maintained regularly. If damage, shedding or cracks are found, they should be repaired in time to prolong the service life of the refractory mud.

Please note that the above introduction only provides a general usage method. Specific refractory mortar use and application procedures may vary by product type, application scenario, and manufacturer's guidelines. Therefore, before using refractory mud, it is recommended to refer to the product manual and manufacturer's recommendations, and strictly follow the relevant safety operating procedures to ensure construction quality and personnel safety.
