Industry Knowledge of Alumina-based Plastic Refractory Patching Paste

Alumina based plastic refractory patching paste is a highly efficient and reliable product used extensively in the refractory industry. It is composed of high-quality alumina, high-temperature bonding agents, and various functional additives. The product has been widely used in the repair and maintenance of high-temperature equipment such as industrial furnaces, kilns, boilers, and incinerators.

Alumina based plastic refractory patching paste can be divided into different grades based on its chemical composition, density, strength, and thermal properties. Grade classification is based on the percentage of alumina content and the size of the particle distribution. The higher the percentage of alumina content, the higher the grade of the product.

The technical parameters of alumina based plastic refractory patching paste include chemical composition, particle size distribution, water content, bulk density, and cold crushing strength. Generally, the alumina content ranges from 70% to 90%, and the particle size distribution ranges from 0-6mm. The water content should be ≤ 3%, and the bulk density and cold crushing strength must meet industry standards to ensure safe and effective use.

The production process of alumina based plastic refractory patching paste involves mixing high-quality alumina powder, high-temperature bonding agents, and various functional additives with a suitable amount of water to form a plastic mixture. The mixture is then shaped into the required form and cured at a specific temperature. The curing temperature, time, and environment significantly affect the product's quality and performance.

In conclusion, alumina based plastic refractory patching paste is a high-quality and effective product widely used in the maintenance and repair of high-temperature equipment in various industries. Its level classification, technical parameters, and production process can ensure its high quality and reliability. With the continuous improvement of production technology, alumina based plastic refractory patching paste will play an increasingly important role in the refractory industry.
