Advantages of Spraying Refractory Plastics

A cement rotary kiln is an important thermal equipment for producing cement clinker. In traditional cement rotary kiln maintenance operations, refractory castables are mostly used for repair. Although the construction of refractory castables is much simpler than refractory bricks, it still cannot meet the requirements of quick repair of cement kilns. Therefore, companies have gradually accepted the use of refractory plastics that do not require formwork or baking for quick repairs. Rongsheng Refractory Plastic Manufacturer can provide high-quality refractory lining materials for cement rotary kilns, including various anti-stripping bricks, anti-erosion bricks, insulation bricks, refractory and wear-resistant castables, wear-resistant plastics, etc. Contact Rongsheng for free samples and quotes.

Performance comparison between spray plastic and traditional plastic

Traditional refractory plastic is mostly applied by hand and ramming. Although it is much better than refractory castable in terms of performance and construction process, for production lines with a daily output of 5,000 tons and 10,000 tons, one day of delay in maintenance will result in a loss of millions.

Refractory Plastics for Rotary Kiln Lining

With spray plastic, there is no need to worry about these problems. The performance of the plastic material used in spray plastic is equivalent to that of traditional refractory plastic, and the integrity is good during construction, and the construction body rarely delaminates. In terms of construction efficiency, the construction speed is several times faster than that of traditional refractory plastic. Spray plastic is used in construction to reduce the damage to construction personnel and construction bodies caused by vibration. At the same time, spray plastic is not restricted by the structure of the construction body, and construction can be carried out even in complex structures.

Effect of spray plastic refractory

In actual spraying operation, professional spray plastic construction tools are required. In terms of construction efficiency, spraying construction produces 2.7t per hour, while traditional ramming construction produces 0.5t per hour.

In terms of construction quality, spray plastic can fully exert the same effect as ramming plastic. It is even better than traditional refractory plastic in terms of construction body integrity and seismic performance.

In terms of performance, spray plastic has been used in the cement rotary kiln feed port, preheater and dust collector inner tube of a large cement production enterprise. After 1 to 2 years of use, no obvious erosion or peeling has occurred.

From actual use, it can be found that the use of spray plastic can completely replace the traditional ramming plastic construction method. It is the key development direction of the construction of amorphous refractory materials such as refractory plastic and refractory castables in the future.
