Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. The standard proposed by China Building Materials Federation. This standard by the National Standardization Technical Committee heat insulating material (SAC/TC191) centralized. This standard was drafted. Nanjing Fiberglass Research and Design Institute Limited, the national glass fiber product quality supervision and inspection center. The main drafters of this standard. Cui Jun, Chen Lihua, ROCKETS, Yang Chao. Mineral cotton blanket-like low-density thermal insulation material evaluation method

1 Scope

This standard specifies the density and thickness by selecting a specific product, measure the density and thickness, the use of protective hot plate or heat flow meter Determination Thermal conductivity, and using calculations and interpolation method to determine the density of thermal insulation blanket. This standard applies to the density range 6.4kg/mineral blanket-like insulation material m3 ~ 48kg/m3 of.

3 Definitions

Terms and definitions GB/T 4132 defined apply to this document. Principle 4 Blanket insulation material of low density, which density distribution is poor, resulting in the distribution of the thermal conductivity is not uniform. In order to evaluate such production The thermal conductivity and thermal resistance of products, and we have a number of representative samples of the density, thickness and thermal conductivity of the test, and the fitting The thermal conductivity of the density curve, using interpolation of its thermal conductivity and thermal resistance were evaluated. Low-density blanket relations insulating material thermal conductivity and density of the formula (1) as follows. λ = a bD c/D ... (1) Where. λ --- thermal conductivity of the sample, in units of watts per meter Kelvin [W/(m · K)]; --- The D sample density in kilograms per cubic meter (kg/m3); A --- Product parameters thermal conductivity and density relation, which corresponds convection heat conduction; b --- products thermal conductivity and density parameters of the relationship between the corresponding solid thermal conductivity; Parameter c --- products of thermal conductivity and density relation, the corresponding thermal radiation.

5 Steps

5.1 Sampling It should be adopted in a representative sample and the sample taken to avoid damage to the recommended 7m2 ~ 14m2 sample. ......
