1. Refractory plastic uses
Refractory plastic is a special refractory material with the characteristics of viscosity, plasticity and easy molding. It is widely used in the maintenance, patching, sealing and coating of high-temperature equipment. Its main uses include the following aspects:
1.1. Maintenance of thermal equipment: Refractory plastics can be used to partially repair, seal and reinforce high-temperature furnaces, heat treatment furnaces, glass kilns, etc.
1.2. Foundry industry: Refractory plastics can also be used for the lining, repair and reinforcement of various furnaces, heating furnaces and crucibles in the foundry industry.
1.3. Electric power industry: In the electric power industry, refractory plastics are widely used in the anti-corrosion, insulation and reinforcement of high-temperature equipment such as boilers, generators and chimneys.
1.4. chemical industry: Fire-resistant plastics can also be used for patches and coatings on reactors, storage tanks, pipelines and other equipment in the chemical industry.
In short, refractory plastics have good high temperature resistance, corrosion resistance and wear resistance, and can provide a convenient and economical solution for the maintenance and modification of high temperature equipment.
2. How to use refractory plastics
Refractory plastic is a special refractory material, and its use is usually as follows:
2.1. Material preparation: Mix the required refractory plastic and water evenly in proportion to make a mud.
2.2. Surface treatment: Clean, polish and rust-remove the surface of the equipment that needs to be repaired or coated to ensure bonding strength and coating firmness.
2.3. Construction operation: Use scrapers, spray guns and other tools to apply or spray refractory plastic to the parts that need to be treated. Pay attention to uniform thickness and avoid problems such as air trapped gaps.
2.4. Curing treatment: After the refractory plastic coating is completely dry, heat and solidify it, usually above 600°C. The time depends on the material type and thickness.
It should be noted that different brands and models of refractory plastics have different construction requirements and usage methods. You should read the product instructions carefully and refer to the advice of professionals. In addition, when using refractory plastics, you need to pay attention to safety precautions and avoid contact with the skin and respiratory tract, especially during the heating and curing process to avoid the generation of harmful gases and dust.
