Testing of the thermal properties of the coating The thermal properties of the coating include the heat resistance, thermal life, thermal insulation and thermal shock resistance of the coating. The main properties are heat resistance and thermal insulation, which are two different properties. The mechanism and test methods are both related and different. Disperser / SPAN>
1. Inspection of coating heat resistance
(1) Spraying the required test on a steel plate with a thickness of 1 mm, the coating thickness is 0.2-0.4 mm, and then heating the steel plate of the normal layer with an oxygen-bright flame to determine the time required to burn the first layer and the steel plate. And use this to assess and compare the heat resistance of the coating. This test is actually the melting point of the segmented layer material and the maturity life to measure the heat resistance of the coating.
(2) In addition to the upper method, the heat resistance of the layer can also be evaluated by the trial of the high temperature air resistance of the normal layer. Firstly, the oxidation resistance of the layer itself can be determined, and the maximum amount of the layer 1 l will be separated from the base material. The lower layer is used as a sample of the roughness meter. After cleaning and weighing, put it into the heating medium. Keep it for 1-2 hours, take the sample from P, cool it at room temperature, and repeat the weighing. The test results show the variation of the mass of the sample with the test time, and visually check the oxidation of the coating. Secondly, the coating can be used to determine the high-temperature gasification protective dispersing function of the substrate, and the substrate with the coated and fixed thickness coating is used as the substrate. After the sample is weighed, put it in the air oven that has been warmed up (the furnace temperature is l~13°C), and observe the state of the sample in the furnace regularly. If the coating is damaged, record the time and test the east, if it is coated after 24h. The layer is not damaged, the sample is taken out of the furnace, and naturally cooled at room temperature. If the layer is still intact after cooling, the sample is weighed and then placed in the furnace and the above test is repeated until the coating is destroyed. After the test The sample is cut open to check the ili1 formation of the matrix material, and the coating is compared to the high temperature hydrogenation of the substrate according to the time and the weight loss of the sample. Performance. (Related instruments: furnace temperature tracker)
According to the high temperature oxidation resistance of the coating itself and the protection ability of the high temperature oxidation of the dispersion machine substrate, the heat resistance of the coating can be comprehensively evaluated.
2, the thermal insulation of the coating test layer and the thermal conductivity of the coating and the boundary of the substrate, can assess and verify the thermal insulation of the coating. Measuring the thermal conductivity of the coating requires a special set of testing equipment, including several parts: a heat source device for heating a sample, a device for measuring a heat flow rate of the heated sample, a moving mechanism of the sample, and a temperature measurement and automatic recording device for the sample (related instrument: furnace temperature tracker)
