Question:

What are the specific specifications of the external wall insulation material re-examination?

What are the specific specifications of the external wall insulation material re-examination?

Answer:

Mainly to see its bulk density, flame retardant and thickness
This material depends on what material, basically the material of the technical procedures which have requirements, such as inorganic insulation mortar, approach re-test: compressive strength, bulk density, thermal conductivity, thermal conductivity should be punished Every item of insulation material will be re-tested.
External wall insulation re-test work to meet the "GB-2007 building energy efficiency construction quality acceptance norms" requirements. Test items and their re-test items . glass wool insulation board: thermal conductivity, density, compressive strength or compressive strength. . polymer bonded mortar: bond strength. . alkali-resistant mesh cloth: mechanical properties, corrosion resistance. . the scene energy-saving drill heart test: at least three groups of sampling. . the scene pull test: at least three groups of samples.
