Carbon paste sample roast experiment
Introduction
Carbon paste is an important type of aqueous suspension colloid, which can be used to prepare paints and other coatings, batteries, etc., because of its good stability and wide range of applications. The roasting of carbon paste samples is an important experiment to judge the quality of carbon paste, and it is also the most used method for judging carbon paste. Through the test results obtained, the effect of roasting on the properties of carbon paste and its reliability can be evaluated, so that the quality of the carbon paste can be determined.
Experimental procedure
In this experiment, the carbon paste sample roasted under the experimental conditions was used. The experimental conditions were: temperature 500 ℃, time 30 minutes. The sample was placed in an electric furnace preheated to 500 ℃, and the furnace was started for 30 minutes to observe the roasting effect.
Test result
After roasting for 30 minutes, the temperature of the sample was still stable at 500 ℃, and the sample was roasted without cracking and spalling. The color of the roasted sample did not change significantly and even showed a light brown hue. After observation by the naked eye, the surface of the sample was not seen to thicken. After the test, the shape of the sample was still the same as before the test.
Conclusion
The experimental results show that under the experimental conditions, the carbon paste sample can be roasted up to 500 ℃ without cracking and spalling, and the color and shape of the sample can be maintained relatively well. Therefore, the test results are satisfactory and the roasting quality of the sample is good. However, the specific performance of the carbon paste must be judged from the parameters from related test.
