Common problems in the use of refractory clay

Common problems encountered during the use of refractory clay include cracking, weak adhesion, and poor high temperature resistance. To address these issues, here are some effective solutions:

Refractory Clay Cracking

Choosing High-Quality Refractory Clay:

When purchasing, choose refractory clay products with reliable quality and a reputable brand name, and avoid inferior products. High-quality refractory clay is typically darker in color, denser in texture, and less prone to cracking.

Controlling the Construction Temperature:

During construction, carefully control the working environment temperature to avoid excessively high or low temperatures that may affect the refractory clay. A suitable temperature promotes uniform curing of the refractory clay and reduces the risk of cracking.

Appropriate Construction:

During construction, follow the instructions in the instructions and avoid excessive compression or stretching of the refractory clay. Ensure the construction surface is flat, dry, and free of oil, dust, and other debris to improve the refractory clay’s adhesion and crack resistance.

Weak Refractory Clay Adhesion

Cleaning the Base:

Before construction, ensure the base surface is clean and dust-free to improve the refractory cladding’s adhesion. Use a wire brush, scraper, or other tool to remove dust and debris from the base surface.

Using a Binder:

During construction, an appropriate amount of binder can be added to improve the refractory cladding’s adhesion. The choice of binder should be determined based on the type of refractory cladding and the environment in which it will be used.

Enhancing Construction Techniques:

During construction, ensure that the refractory cladding is applied evenly to ensure a tight bond with the base. Avoid vibration and impact during construction to prevent damage to the refractory cladding’s adhesive layer.

Poor High-Temperature Performance of Refractory Clay

Selecting Appropriate Materials:

When selecting refractory cladding, choose the appropriate type based on the temperature requirements of the specific environment. For example, high-alumina refractory cladding and clay refractory cladding are suitable for refractory brick masonry in different temperature ranges.

Increasing the Material Ratio:

The refractory cladding ratio can be appropriately increased to improve its high-temperature performance. However, it is important to note that excessive amounts of refractory cladding may cause construction difficulties or degrade performance, so the ratio should be strictly controlled.

Improving Construction Quality:

During construction, care should be taken to ensure the uniformity and density of the refractory cladding to improve its high-temperature performance. Furthermore, proper curing and drying should be performed after construction to ensure the refractory cladding’s full performance.

In summary, in order to solve the problems of cracking, weak bonding and poor high temperature resistance that may occur in the use of refractory mud, they can be solved by selecting high-quality materials, controlling the construction temperature, reasonable construction, cleaning the base, using adhesives, strengthening the construction process, selecting suitable materials and increasing the material ratio. These measures will help improve the use effect of refractory mud and extend its service life.
