1. chemical composition
The main chemical composition of aluminum carbohydrate is carbon, aluminum, silicon, calcium, magnesium, titanium and other elements. Among them, carbon is the most important component, and its content is usually 10% to 25%. In addition, the content of aluminum is also very high, generally 10% to 20%. The content of silicon and calcium is relatively low, usually within 5%. The content of these elements has a great influence on the performance and service life of the aluminum carbohydrate.
2. physical properties
The physical properties of aluminum carbon ports mainly include density, thermal expansion coefficient, thermal conductivity and heat capacity. Among them, the density is generally between 1.9~2.4g/cm³; the coefficient of thermal expansion is between 6.5~8.5 × 10 ^-6/℃; the thermal conductivity is between 15~30W/(m · K); the heat capacity is between 0.5~1.0kJ/(kg · K). These indicators can reflect the thermodynamic properties and thermal motion state of aluminum carbohydrate, and also have a great influence on its service life and stability.
