Rubber and plastic insulation materials have good thermal insulation performance and low thermal conductivity, which can effectively reduce the heat conduction when air flows. When the air conditioning system is working, the use of rubber and plastic insulation materials can effectively reduce the heat loss inside the air conditioning duct and improve the energy efficiency of the air conditioning system.

Specification requirements for rubber and plastic insulation of air conditioning duct

In addition, the rubber and plastic insulation material also has the functions of moistureproof, mildew proof, flame retardant, etc., which can improve the safety and durability of the air duct. Next, the Utson rubber and plastic manufacturer will explain the specification requirements for the use of rubber and plastic insulation for air conditioning ducts.

1. Material selection: select rubber and plastic insulation materials that meet the relevant national standards to ensure that the quality and performance of the materials meet the requirements. Such as GB/T17794-2008 "polyurethane powder foam insulation material", GB/T10801-2008 "rubber foam plastic products" and so on.

2. Thickness requirements: Determine the appropriate insulation layer thickness according to the design requirements and environmental conditions of the air conditioning system. Under normal circumstances, the thickness of the rubber insulation layer of the air conditioning duct needs to be calculated. At present, the thickness of rubber and plastic insulation materials used in air conditioning ducts with a diameter of less than 100mm shall not be less than 15mm, and the thickness of air conditioning ducts with a diameter of more than 100mm shall not be less than 20mm.

3. Density requirements: The density of rubber and plastic insulation layer should meet the requirements of relevant specifications to ensure the stability of insulation performance and materials. The density of rubber and plastic insulation materials commonly used in air conditioning ducts is generally 40-45kg/m.

4, fire protection requirements: rubber insulation layer should meet the fire protection requirements, the general requirements to achieve a certain fire rating, to ensure safety. At present, the fire rating of rubber and plastic insulation materials is B1 level flame retardant and B2 level combustible.

5. Installation and use: The installation and construction of rubber and plastic insulation materials shall meet the requirements of relative specifications or product instructions. For example, the rubber and plastic insulation layer should be closely attached to the surface of the air duct without gaps to avoid the thermal bridge effect. Use professional installation tools and fixing materials to ensure that the insulation layer is firmly and reliably fixed.
