Rubber and plastic generally refers to rubber and plastic insulation materials. It is a flexible closed-cell foam material that is mixed and processed by rubber and plastic through a special process. Usually has a soft texture, delicate surface and certain elasticity. Various colors, common ones include black, gray, etc.
Working Principle:
Rubber and plastic rely on the air in their closed-cell structure to prevent the transfer of heat. The thermal conductivity of air is low, and the closed pores in the material can effectively reduce heat convection and heat conduction, thereby achieving the effect of thermal insulation.
Performance:
1. Thermal insulation performance: It has a low thermal conductivity and can effectively reduce heat loss.
2. Flame retardant performance: Some products have certain flame retardant capabilities and can prevent the spread of fire to a certain extent.
3. Sound insulation performance: It has a certain absorption and blocking effect on sound and can reduce the spread of noise.
Advantage:
1. Good thermal insulation effect: it can significantly reduce energy consumption and improve energy utilization efficiency.
2. Soft and easy to construct: soft in texture, easy to cut and install, and adaptable to various complex-shaped pipes and equipment.
3. Waterproof and moisture-proof: The closed-cell structure makes it have good waterproof and moisture-proof properties and is not easy to absorb water.
4. Green and environmentally friendly: generally does not contain harmful substances and is friendly to the human body and the environment.
5. Long service life: It has good weather resistance and durability, and can maintain stable performance for a long time.
Characteristic:
1. High obturator rate: The obturator structure is uniform, ensuring good insulation and waterproof performance.
2. Good elastic recovery: it can quickly return to its original shape after being compressed and is not easily deformed.
3. Light weight: reduces the burden of installation and transportation.
Use:
1. Central air-conditioning system: Insulate air-conditioning pipes to reduce energy loss, improve the operating efficiency of the air-conditioning system, and reduce energy consumption.
2. Building HVAC system: used for insulation of heating and ventilation ducts, such as radiator ducts, floor heating ducts, etc., which helps to maintain indoor temperature stability and save energy.
3. Industrial pipelines: Provide insulation for various types of pipelines in factories, such as steam pipelines, chemical pipelines, etc., to prevent heat loss, ensure temperature conditions during the production process, and also reduce the formation of condensation water on the surface of the pipelines.
4. Refrigeration and freezing system: Used in the pipes and cabinets of cold storage, refrigerated trucks and other equipment to effectively maintain low-temperature environments and reduce the operating costs of refrigeration equipment.
5. Ships and marine engineering: Insulate pipes and equipment on ships to resist erosion and temperature changes in the marine environment.
6. Solar water heater system: Insulate hot water pipes to ensure hot water delivery efficiency and reduce heat loss.
7. Petrochemical industry: Used on pipelines and storage tanks in the petrochemical industry to ensure stable temperature of materials and improve production safety and efficiency.
In short, rubber and plastic insulation materials play an important role in various systems and equipment that need to maintain temperature stability and reduce energy loss, helping to achieve energy conservation, improve system operation efficiency, and ensure the comfort and safety of production and life.
