1.The dry anti-seepage refractory material is an amorphous bulk refractory material which is scientifically graded and mixed with different grades and different types of refractory raw materials.
2.Dry anti-seepage refractory material is a new type of furnace building refractory material developed in the 1990s in the world. Fireproof dry anti-seepage material is made of refractory and anti-seepage. The refractory material is made up of different grades and different types of refractory materials to replace the refractory bricks and alumina layer in the lining of the electrolytic cell. The anti-seepage refractory material principle is that the dry anti-seepage material can react with the electrolyte permeated through the cathode carbon block to form a dense vitreous nepheline layer, thereby preventing the continuous penetration of the liquid electrolyte and steam, ensuring that the insulation layer is not damaged, refractory material plays the role of refractory, anti-seepage, anti-electrolyte pollution and maintains the thermal balance of the electrolyzer.
Dry Anti-Seepage Refractory Material Properties
1.Dry anti-seepage material refractory with simple construction, good thermal insulation effect and anti-penetration.
2.Dry anti-seepage refractory material can prevent the penetration and erosion of aluminum liquid and electrolyte, thus prolonging the service life of the electrolytic cell.
3.Dry anti-seepage refractory material construction is quick and convenient

A new dry anti-seepage refractory material was prepared by using high-quality coke as the main raw material, adding albite and quartz. The amount of albite added is preferably 3%, the amount of quartz added is preferably 8%. The specification of the prepared dry anti-seepage refractory materials are: w(Al2O3 + SiO2) ≥ 90%, and the thermal conductivity at 910 ℃ is 0.497 w·(m·k)-1. Refractory material can effectively react with the electrolyte to form a dense glaze layer, prevent the electrolyte and aluminum liquid from continuing to penetrate downward, greatly reducing the consumption of cryolite, and the fireproof dry anti-seepage material of the lower part of the glaze remains loose and can be used repeatedly.
Dry Anti-Seepage Refractory Material Application
The refractory material dry anti-seepage is used in the lining of the electrolytic cell to replace the refractory brick and the aluminum oxide layer in the lining of the electrolytic cell. The anti-seepage refractory material principle is that the dry anti-seepage material can react with the electrolyte permeated through the cathode carbon block to form a dense vitreous nepheline layer, thereby preventing the continuous penetration of the liquid electrolyte and steam, ensuring that the insulation layer is not damaged, refracoty dry anti-seepage material plays the role of refractory, anti-seepage, anti-electrolyte pollution and maintains the thermal balance of the electrolyzer.
Dry Anti-Seepage Refractory Material Effection
1.In the lining design of modern aluminum cells, the 850 ° C isotherm is controlled within the refractory layer. On the one hand, the electrolyte is not crystallized in the carbon lining to cause carbon volume expansion, and on the other hand, the electrolyte does not penetrate into the heat insulating layer and react with the heat insulating material, thereby reducing the heat insulating property of the bottom of the groove. The impermeability and low thermal conductivity of the dry anti-seepage refractory material meet the needs of the electrolysis cell. At the same time, since the anti-seepage layer is made of bulk material, refractory material can absorb the expansion of a part of the carbon block and effectively slow down the bottom of the furnace. Therefore, fireproof dry anti-seepage materials have been used more and more widely in the aluminum industry.
2.Dry anti-seepage refractory materials have a positive effect on extending the service life of the cathode liner. On the one hand, refractory material can buffer the uplift of the cathode carbon block, on the other hand, refractory material can enhance the heat preservation capacity of the bottom of the tank, reduce the heat loss at the bottom of the tank, and increase the temperature of the cathode carbon block itself, reduce the temperature gradient between the upper and lower sides of the cathode carbon block. Since the dry impervious material can form a 5-15 mm thick, dense vitreous nepheline barrier layer with the infiltrated electrolyte, this barrier layer prevents the electrolyte from continuing to penetrate downward and protects the lower thermal insulation material. On the other hand, because the barrier layer has plasticity and the particle layer has a certain compressibility, refractory material dry anti-seepage can effectively alleviate the problems such as the bottom of the furnace and the deformation of the shell. Therefore, in the process of building an aluminum electrolytic cell, dry anti seepage refractory material can be directly placed on the insulating brick, and after compaction, the cathode carbon block is directly placed on the upper part to replace the traditional refractory brick and alumina masonry.
