This standard by the National Standardization Technical Committee paint pigment. This standard was drafted. CNOOC Changzhou coating Chemical Research Institute. The main drafters of this standard. Zhao Ling. Coatings anti-adhesion assays1 ScopeThis standard specifies a certain temperature or between a coated surface and the other unpainted surface between two surfaces with a coating of coating Under conditions of pressure and placed in contact with a certain time after the test method for anti-adhesion properties. This standard applies to the study of painted wood products in storage, packaging and transportation process must face to face or back-stacked but not Coating adhesion formation and damage the case. This test method is the use of pressure, temperature, time and other factors in the laboratory evaluation of coating on wood substrates blocking resistance.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.

Principle 4 Required or agreed on wooden substrate to simulate as much as possible the actual production process and curing conditions for the preparation of test mode with a coating. then These test panels have been painted in the manner prescribed piled up and subjected to a certain pressure thereon, is placed at a sufficient temperature prescribed Time to make any adhesion tendency have revealed. After removing the pressure generating spot checks if there are any painted surface adhesion or pressure after Point (indentation) phenomenon. NOTE. If the production of decorative condition has been specified and known, then the method of application, the substrate, coating thickness and coating curing should simulate these conditions as much as possible. But it may also be some harsher conditions accelerated test, in addition to such pressure, temperature, time and other conditions, but can also provide humidity and other test conditions.5 Apparatus and materials5.1 oven maintained within the specified or agreed temperature range of ± 2 ℃. 5.2 the load, such as weight, load mass is usually selected in the range of 100g ~ 1000g. 5.3 water sandpaper, 400 mesh.6 SamplingAccording to the provisions of GB/T 3186, and take representative samples of the test product. According to the provisions of GB/T 20777, the inspection and preparation of test samples. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23982-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23982-2009_English as soon as possible, and keep you informed of the progress.
