[China paint information] according to the analysis of reportlinker, a consulting company, the official of Anhui Provincial Bureau of Quality Supervision recently announced the results of provincial supervision and spot check of insulation material products in 2016. A total of 20 groups of thermal insulation products were sampled this time, involving Hefei, so there must be corresponding mechanical performance indicators to characterize 19 thermal insulation products in Wuhu and Chuzhou. However, petrochemical plastics degrade slowly or even cannot degrade, and the product sampling qualification rate is 100%
this sampling inspection is based on the implementation rules for supervision and random inspection of building insulation materials products, gb/t molded polystyrene board thin plastered external wall external insulation system materials, db34/t inorganic insulation mortar wall insulation system, db34/t rock wool board thin plastered external wall external insulation system, db34/t expanded perlite insulation board external wall external insulation system, q/qh metal faced rigid polyurethane sandwich board GB classification of flammability of building materials and products, etc. The inspection items are: density, mass per unit area, compressive strength, thermal conductivity, tensile bond strength, softening coefficient, heat storage coefficient, compression folding ratio, easy decomposition, operable time, flexibility, dimensional stability, mass moisture absorption, hydrophobicity, water absorption (partial immersion), combustion performance (A1, B1, B2), oxygen index, water absorption, alkali resistance, water resistance, radioactivity, etc
