        Thermal insulation material selection of attention

        Author:管理員Time:2014-07-12 11:05:26 Read: 1 Times
        Temperature tolerance range
        Thermal insulation materials are divided into: according to the scope of the materials of heat resistance, medium temperature heat preservation thermal insulation material at low temperature heat insulation material, high temperature thermal insulation material.
        Heat resistance performance of selected thermal insulation materials must conform to the use environment.
        Choose low temperature thermal insulation material, generally choose classification temperature is lower than the long-term use of temperature of about 10 to 30 ℃ or so of the material.
        Select medium temperature and high temperature thermal insulation materials, heat insulating materials generally choose classification temperature higher than the long-term use of temperature of about 100-150 ℃.
         
        The physical form and characteristics of the material
        Thermal insulation material forms are: board, carpet, cotton, paper, felt, special-shaped products, textiles, etc.
        Physical properties of different types of insulation material (machinability and wear resistance, pressure resistance, etc.).
        Morphology and physical properties of the selected thermal insulation materials must conform to the use environment.
         
        Chemical properties of materials
        Different types of thermal insulation materials chemistry (waterproof, corrosion resistance, etc.).
        Chemical properties of the selected thermal insulation materials must conform to the use environment.
        Materials, heat preservation and heat insulation performance
        The thickness of the insulating heat insulation layer in the system often has a maximum value.
        Using the selected thermal insulation material of insulation layer thickness must be within the maximum required.
        Requiring heat insulation layer thickness is thinner in some often need to choose good heat preservation and heat insulation heat preservation and heat insulation performance materials (such as: send heat insulation soft mat, soft mat).
         
        Level of the environmental protection material
        The environmental protection level for the selected thermal insulation material must meet the design requirements.
        Some export products often need to use environmental protection level is very high thermal insulation material.
         
        The cost of the material
        Determine the scope of the good material, according to the material price business accounting cost, choose the best cost-effective material.
        Together, said the choice of thermal insulation materials is to choose according to use environment out of shape, physical characteristics, chemical characteristics, heat preservation and heat insulation performance in line with the use environment, environmental protection level meet the design requirements of thermal insulation material, after cost accounting, eventually determine the thermal insulation material to be used.
