High-Temperature Physical Property Tester This is a physical property testing instrument used in chemistry, materials science, metallurgical engineering technology, physics, and other fields. The following describes the applications of high-temperature physical property testers and precision high-temperature contact angle measuring instruments.
1. Measure the wettability of liquid metal on the substrate under high-temperature vacuum conditions, and evaluate the wetting process and adhesion performance of different materials under high-temperature vacuum conditions.
2. Study the wettability between metal and ceramic composite materials, and measure the contact angle of ceramic materials when metal materials melt under high-temperature vacuum conditions.
3. Study the brazing process and wetting spreading process of brazing filler metal on the substrate, and dynamically analyze the contact angle and wetting process of the brazing filler metal at high temperatures.
4. Measure the changes and differences in the contact angle of metals on different substrates under different high-temperature conditions and different gas protection environments.
5. Analyze the contact angle between the coating and the substrate, the wetting process and spreading mechanism between the coating and the substrate, and study the difference in wettability of the coating under different temperatures and atmospheres.
6. Study the contact angle between liquid and solid, evaluate the adhesion performance between liquid and solid, and analyze the surface free energy of the solid.
7. Analyze the contact angle between solder and solder body and the surface tension of the solder solution to effectively improve the welding strength.
8. Analyze the surface tension of welding liquids such as steel liquid, aluminum liquid, and copper liquid at high temperatures; through the analysis of contact angle and surface tension, control the reasonable wetting range, and find an effective method for removing furnace slag during smelting.
Characteristics of High-Temperature Physical Property Tester:
1. External and internal dual temperature monitoring system, which can detect the temperature inside the heating furnace in real time.
2. It has a special high-temperature left and right contact angle fitting, using the differential circle method fitting, with an accuracy of ±1℃.
3. 1700℃ under normal temperature and pressure, 1500℃ under normal temperature and vacuum.
4. Equipped with a dual-channel inert protection device, some process gases can be used to protect the internal metal simultaneously or individually.
Application Cases of High-Temperature Physical Property Tester:
Wettability of aluminum alloy after heating to 1320℃ and melting on the metal substrate.
High-temperature physical property tester wetting process
After heating to 1320℃ and melting, the contact angle between the alloy and the metal substrate surface is 47.6°, showing hydrophilicity. Using special high-temperature left and right contact angle fitting, using differential circle fitting, the wettability angle of metal samples in a high-temperature environment can be easily measured, with an accuracy of up to ±1°.
The high-temperature physical property tester can not only measure the contact angle and surface tension of metal liquid under high temperature and high vacuum, but also measure the contact angle, surface free energy, interfacial tension, etc. at room temperature. With stable heating, high vacuum degree, and comprehensive functions, it can be widely used in the research fields of metal materials and ceramic materials.
