Single wall carbon tube high-temperature furnace

Single walled carbon nanotubes (SWCNTs) are one-dimensional tubular nanomaterials formed by curling a single layer of graphene, typically with a diameter of 0.4-3 nm and a length of several micrometers or even centimeters. Its structure is similar to a honeycomb shaped cylinder composed of a carbon six membered ring (benzene ring), with both ends typically sealed by fullerene (such as C ₆₀) hemispheres.

At present, the main production method in industrial production is chemical vapor deposition (CVD)

Principle: Hydrocarbons (such as methane and ethylene) decompose on the surface of metal catalysts (Fe, Co, Ni, etc.), and carbon atoms grow into SWCNTs on the substrate.

Floating catalyst CVD: Catalyst precursors (such as ferrocene) react with carbon sources (such as ethanol or methane) in the gas phase.

Advantages: Strong controllability, suitable for large-scale production, and directional growth.

Our company independently developsSingle wall carbon tube high-temperature furnace After multiple improvements and upgrades, it has now reached the standards of continuous production, high output, and low energy consumption, and can be directly applied in production.

Product Features:

1. Adopting stainless steel explosion-proof design, locally equipped with water cooling layer protection, and thickened internal low-temperature layer design, the energy consumption is much lower than similar products.

2. Adopting an integrated design, it is easy to operate and has a beautiful appearance.

3. The heating element adopts branded components, which significantly improves its service life and is superior to similar products.

4. Adopting a multi-stage atomization ultrasonic feeding design, the feeding is uniform and consistent, effectively controlling directional growth and improving batch consistency.

5. The equipment is equipped with a vacuum system interface, which can quickly replace the atmosphere inside the furnace.

6. The equipment is equipped with flammable and explosive gas detectors that can detect the surrounding environment around the clock.

7. There is a rotary shaft feeding system installed in the receiving bin, which can achieve continuous feeding without stopping the machine.

8. Multiple safety chain protection mechanisms, including over temperature alarm, intermittent protection, insufficient water pressure protection, excessive air pressure protection, gas leakage protection, and leakage protection.
