Refractory Protective Shells

Refractory protective shells are mainly used to protect refractory materials in building structures from erosion and damage by the external environment. It can be divided into the following types:

1. Brick protective casing: mainly composed of bricks, suitable for wrapping and protecting refractory materials. Brick protective shells have good fire resistance and compression resistance, which can effectively stop the spread of fire and protect the structure from heat sources.

2. Cement-concrete protective shell: It is made of cement, sand, gravel and other materials, with high fire resistance and corrosion resistance. It is suitable for concrete pouring and covering of refractory materials, and can play a good protective role.

3. Steel plate protective shell: welded by steel plate, with high impact resistance and fire resistance. It is suitable for covering and fixing the refractory materials, which can effectively improve the bearing capacity and fire-resistant performance of the structure.

4. Bonding protective shell: It is made of special adhesive and fiber material, with better bonding and fire resistance performance. It is suitable for the protection of complex shapes of structures, and can effectively improve the stability of the structure and fire-resistant performance.

These protective shells can effectively extend the service life of fire-resistant materials, improve their fire-resistant performance and stability, and guarantee the safety and stability of building structures. In building design and construction, the selection of appropriate refractory protective shells is of great significance in improving the overall performance and safety of building structures.
