FIELD: physics.
SUBSTANCE: method of testing binder involves sample preparation. Testing is carried out on a polymer of the hardened binder. Paper-resin samples are prepared, part of which undergo hydrothermal treatment by boiling. The value of mass loss is determined and then used to determine thermohydrolytic stability on mass loss, and the other part undergoes hydrothermal treatment by holding in water at high temperature. The value of formaldehyde extraction is determined and then used to determine thermohydrolytic stability on formaldehyde extraction, and preliminary evaluation of the possibility of using the binder to produce water- and weather-resistant materials is made based on the obtained values.
EFFECT: high efficiency of the method of testing binder, excluding the effect of different additives and wood filler.
