System Composition

·Micro high temperature furnace body

The furnace adopts high-purity alumina fiber or zirconia fiber products, with built-in high-quality resistance heating elements (such as iron chromium aluminum or silicon carbide), with a maximum working temperature of 1100 ℃, and supports multi-stage programmable curve temperature control. Specially designed inlet and exhaust ports for the front-end process gas, controlled micro flow inert gas (N ₂/Ar) is introduced during degreasing to transport decomposition products to the back-end and prevent furnace pollution.

·Molecular pump vacuum unit and condensation capture device

The oil-free high vacuum system is composed of a turbo molecular pump and a two-stage diaphragm/vortex dry pump to ensure cleanliness. The front end of the unit is connected in series with a high-efficiency condenser/filter catcher (liquid nitrogen cold trap or polymer filter), which can solidify and intercept the paraffin and plastic based adhesive cracking products emitted during the degreasing process, effectively protecting the molecular pump and vacuum gauge and extending the maintenance cycle. High vacuum isolation and air release solenoid valve fully automatic logic interlock.

·Precision control and measurement system

Configure a composite full-scale vacuum gauge to display real-time vacuum levels ranging from atmospheric pressure to 10-4.

Core processes and parameters

·Ultimate vacuum degree: ≤ 1.0 × 10-4Pa (clean cold state, after degassing)

·Maximum temperature: 1100 ℃

·Temperature control accuracy: ± 1 ℃, multi-stage programmable (adjustable heating rate and insulation platform, suitable for step-by-step volatilization and removal of adhesives)

·Defatting process path: room temperature → slow heating to 200~600 ℃ (depending on the type of binder), fully thermally decomposed at multiple temperature platforms, accompanied by inert gas carrier gas, and wax deposits collected by condenser condensation.

·Vacuum pumping speed: Molecular pump pumping speed ≥ 60 L/s, pumping to 5 × 10 ⁻⁴ Pa ≤ 30 min under no-load clean state

Core functional features

·Professional degreasing design

Specially designed for the efficient capture and partial pressure control of polymer binders (wax, plastic, PEG, etc.), ensuring thorough and clean removal of binders without contaminating the pump unit, with a degreasing rate of over 99%, directly connected to subsequent high vacuum sintering to avoid secondary pollution or oxidation caused by transfer.

·Integration of high vacuum and wide temperature range

After degreasing, there is no need to remove it. Simply turn off the carrier gas, fully open the molecular pump to pump to 10-4 Pa, and heat up to 1100 ℃ to complete vacuum sintering, annealing, or solid solution aging, truly achieving "one furnace to the end".

·Highly scalable

Reserved interface for residual gas analysis (RGA) in mass spectrometry, which can monitor decomposition products (H ₂ O, CO, CO ₂, hydrocarbons) in real-time during the degreasing process, optimize the process window, and can also be used for material gas release analysis, vacuum heat treatment, ceramic sintering, metal degassing and other broader fields.
