Refractory cement is a special cement material used to bond, seal and repair refractory materials in high temperature environments. The following is how to use refractory cement:
1. Preparation: Before using refractory cement, make sure the construction surface is clean, free of grease and dust. The refractory can be scraped or cleaned as needed for better bonding.
2. Add water and mix: Pour the dry powder of refractory cement into a clean container, gradually add an appropriate amount of water, and master the appropriate ratio of cement to water according to the product manual or experience. Using a stick or mixer, mix the cement and water thoroughly until a uniform paste-like mass forms.
3. Construction method: According to specific needs, it can be constructed by scraping, smoothing, filling and other methods. Refractory cement can be applied to the desired location using a scraper, trowel, sprayer or other suitable implement.
4. Bonding and sealing: Apply refractory cement evenly on the surface of the refractory material to be bonded. Make sure the two surfaces are snug and apply proper pressure to ensure a strong bond. For areas that need to be sealed, refractory cement can be filled into cracks, holes and joints using a scraper or trowel.
5. Repair and Restoration: Where damaged or worn refractory surfaces exist, refractory cement can be used for repair and restoration. After cleaning and preparing the surface, apply refractory cement to the damaged area and use tools to mimic the original shape and texture.
6. Hardening and Drying: After completion of construction, refractory cement needs to be hardened and dried for best results. According to the recommendations on the product manual, it is usually necessary to wait for a certain period of time to allow the cement to fully cure.
Note that the method of application of refractory cement may vary with different brands or models. Therefore, it is recommended to follow the instructions on the product leaflet and follow safe operating procedures, such as wearing appropriate protective equipment and methods of disposing of waste. Before construction, it is best to read and understand the relevant instructions and suggestions, or consult a professional for more detailed guidance.
