Ceramic Material R&D Efficiency: Significance of Dual Thermal Field Design for Improving the Success Rate of Integrated Debinding and Sintering

1. Industry Background: "Process Gap" from R&D to Mass Production

In the development process of high-performance ceramics (such as advanced alumina and zirconia), R&D personnel often face a tricky problem: the debinding and sintering processes completed in small laboratory furnaces often lead to product cracking due to uneven temperature fields or organic residues when scaled up to the pilot scale. The key to improving R&D efficiency lies in whether the equipment can accurately simulate and execute complex "degreasing-sintering" continuous curves in the same space.

2. Technical Interpretation: Core Value of "Dual Thermal Field" Design

The so-called "dual thermal field" design means that the equipment has both an efficient low-temperature convection field and a high-temperature radiation field.

Low-temperature debinding field (convection-driven): The KYN-ZS-TS-500 is equipped with a 9KW fresh air preheating system. Air is preheated through honeycomb catalytic ceramics before entering the furnace chamber, forming uniform convection. This solves the problem of uneven shrinkage of green bodies caused by local cold spots during the critical debinding period of 200℃ ~ 600℃.
High-temperature sintering field (radiation-driven): After the debinding period, the equipment uses 1800-type molybdenum disilicide rods distributed on four sides to provide radiant heat up to 1600℃. Dual electric field switching ensures seamless connection of the process.

3. Selection Guide: How to Evaluate the Success Rate of "Integrated" Equipment?

For institutions seeking to improve R&D efficiency, the following three indicators should be focused on during equipment selection:

3.1 Flexibility and Precision of Temperature Control System

R&D requires frequent adjustment of curves.

Parameter Basis: It must have a temperature control accuracy of ±1℃. The "one-click start" function realized by PLC combined with a touch screen should be able to store multiple sets of process curves. The closed-loop negative feedback system of KYN-ZS-TS-500 can automatically tune PID parameters according to the exothermic reaction of different materials, preventing temperature overshoot.

3.2 Exhaust Gas Treatment and Furnace Self-Cleaning Capacity

The emission efficiency of organic binders directly affects the purity of finished products.

Parameter Basis: Check whether it is equipped with an independently temperature-controlled exhaust gas treatment furnace (operating temperature 700℃ ~ 850℃). Efficient exhaust gas circulation can not only protect heating elements from corrosion by acidic substances, but also ensure no carbon deposition on the inner wall of the furnace chamber, avoiding secondary pollution.

3.3 Consistency of Thermal Performance

Parameter Basis: Inspect the temperature field uniformity. When holding at 1450℃ for 1 hour, the temperature difference should be controlled within ≤ ±10℃. For R&D, this consistency means that laboratory data can be seamlessly transferred to large-scale production.
