4.Refractory plastic micro expansion is widely used in CFB boilers, pulverized coal furnaces and other industrial furnaces such as CFB boilers, pulverized coal furnaces, and other industrial furnaces, through the wall pipe, in the furnace, the flame angle, and the complicated part of the furnace wall.

Micro Expansion Refractory Plastic Construction Instructions

1.The micro expansion refractory plastic can be formed by the method of tamping and compacting. When constructing, the plastic can be manually laid at the required thickness according to the specified requirements, and then hammered with a wind hammer or a hand hammer to penetrate the wall at the top of the furnace. When applied, due to the narrow construction site, Refractory plastic micro expansion can be beaten with long planks. Generally, refractory plastic is not easy to be overweight. The construction surface cannot be shocked like refractory enamel to the surface to produce slurry. Otherwise, refractory plastic is not conducive to the compactness and moisture evaporation of the plastic internal structure. Not easy to smear, smooth.

2.Specific construction beatings with the micro expansion refractory plastic can be divided into two beatings. After the first beating is compacted, according to the local temperature and temperature, when the refractory plastic surface is nearly air-dried, a second beating is performed (usually 3-5 hours interval). This can improve the compactness of the construction and fully achieve the sealing effect.

4. When used in other parts, the plastic refractory can be laid on the use part according to the design thickness requirement. When the construction thickness is greater than 50mm, the d3-4mm wire is used after the tapping is compacted, and the vent hole is perpendicular to the working face. The hole depth is total. Plastic refractory has a thickness of 2/3 and a pitch of 150-250mm, which can be used for exhausting and buffering. Oven is an important part, especially when operating wood plants in the application of wood materials in the maintenance of the oven is directly related to the use and life. However, due to the long cycle of the new power plant project, when the boiler is ignited, the refractory material has been naturally air-dried in the air, and a certain compressive and flexural strength is formed, so there is basically no oven problem. High temperature micro expansion refractory plastics have more water content, and the baking heating rate should be strictly controlled. Especially in the low temperature state, the temperature rise must be slow. If the temperature rises too fast, a large amount of water is discharged from the refractory plastic too quickly, and micro expansion refractory plastic can be similar to other fire-resistant. Concrete causes expansion, cracks, spalling and other undesirable phenomena, affecting the use effect.

Dry Anti-Seepage Refractory Material Meaning

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

Dry Anti-Seepage Refractory Material Forge

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.
