Micro Expansion Refractory Plastic Definition
 
The high temperature micro expansion refractory plastic is composed of a certain grade of refractory aggregate, and a suitable amount of kyanite powder and a binder are mixed at a certain ratio. Refractory plastic micro expansion is a kind of gas-hard material, which has good plasticity at normal temperature, micro-expansion at high temperature, high strength after high temperature, good sealing performance and convenient constructio.
 
Micro Expansion Refractory Plastic Features
 
1. The micro expansion refractory plastic has strong plasticity at room temperature, large adhesion, high strength after natural drying, micro-expansion in volume at high temperature, high refractoriness, good sealing performance and convenient construction.
 
2. The requirements for the micro expansion refractory plastic used are that the content of AliO3 is low, the strength is moderate, the thermal shock resistance is good, and the line change after burning is slightly expanded.
 
3. The micro expansion refractory plastic has the advantages of strong plasticity at room temperature, high adhesion, natural strength after drying, micro-expansion in volume at high temperature, high refractoriness, good sealing performance and convenient construction.

Micro Expansion Refractory Plastic Specification
 

 
Micro Expansion Refractory Plastic Application
 
1.Micro expansion plastic refractory widely used in metallurgy, petrochemical, electric power, building materials and other fields, especially in different parts of power plant boilers.
 
2.Micro expansion plastic is suitable for the cyclone cylinder of the circulating fluidized bed boiler, the lining of the furnace wall and the parts with severe impact and wear of coal ash.
 
3.Fireproof micro expansion plastic widely used in the thermal power industry CFB boiler, pulverized coal furnace and other industrial kiln furnace top wall pipe, furnace flame angle, furnace wall complex parts.
 
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.
 
3.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.
