1. Bond strength test
Bond strength is an important indicator to measure the performance of refractory matter resin powder. During the test, the resin powder can be mixed with aggregate in a certain proportion and pressed under a certain pressure to form a shape, and then its crushing resistance or tensile strength can be measured. Commonly used test methods include compressive strength test, tensile strength test and shear strength test. These tests can provide intuitive data on the bonding performance of resin powder.
2. Durability evaluation
Durability evaluation mainly focuses on the performance of resin powder in harsh environments such as high temperature, oxidation, and erosion. By simulating a high temperature environment, the carbonization of resin powder at high temperature and the strength change of the material after carbonization can be observed. In addition, corrosion resistance tests can be performed to evaluate the stability of resin powder in acid and alkali environments.
3. Thermogravimetric analysis (TGA)
TGA is a thermal analysis technique that can be used to evaluate the thermal stability and thermal decomposition temperature of materials. By measuring the weight change of resin powder during heating, its thermal decomposition temperature and thermal stability can be determined, thereby indirectly evaluating its durability.
4. Scanning electron microscope analysis
Scanning electron microscope is used to scan the cross-sectional morphology of the carbonized product of resin powder, so as to observe its microstructure and judge its structural performance. This method helps to deeply understand the bonding mechanism and durability of resin powder.
5. Practical application test
Apply resin powder to actual refractory materials, and observe its performance by simulating working environment or use conditions. Although this method is time-consuming, it can more truly reflect the bonding strength and durability of resin powder.
6. Reference to industry standards
Refer to relevant industry standards and specifications to evaluate the bonding strength and durability of resin powder. These standards and specifications usually contain detailed test methods and evaluation indicators.
7. Comprehensive analysis
Comprehensively analyze the above test results and data to comprehensively evaluate the bonding strength and durability of refractory matter resin powder. According to the evaluation results, resin powder with better performance can be selected to improve the overall performance of refractory materials.
