The Weibulen 1L Atmosphere Protection Experimental Internal Mixer is primarily used for mixing and dispersion experiments of materials such as titanium alloys, copper alloys, aluminum alloys, and tungsten alloys. The 1L small capacity ensures experiments are completed with minimal material, avoiding waste. It utilizes imported oxygen content detection instruments to ensure accurate readings; the entire machine employs multiple sealing devices to prevent gas leakage, enabling experiments to be completed with minimal gas consumption. Since its launch, the Weibulen 1L Atmosphere Protection Experimental Internal Mixer has gained widespread recognition from research institutions and universities. I: Features of the Weibulen 1L Atmosphere Protection Experimental Internal Mixer

1: The mixing chamber and rotors are made of new alloy steel material, undergoing special vacuum heat treatment, CNC machining, and surface mirror polishing, ultimately achieving overall steel wear resistance and corrosion resistance (salt corrosion, acid corrosion, alkali corrosion, hydrogen sulfide corrosion, and various other types of corrosion).

2: Servo coaxial separation technology, easy cleaning and material change

Utilizing advanced servo coaxial separation technology, the rotor can be separated with one end face as the axis, breaking the bottleneck of traditional internal mixers. The open-close internal mixer effectively controls unnecessary economic losses caused by material contamination. When the mixing chamber opens and closes, the rotor remains suspended in the middle, making cleaning and material change convenient. The rotor is detachable, allowing staff to clean every part, with a full-range, no-dead-zone design.

3: The industry-first vacuum pumping + atmosphere protection mode significantly reduces gas filling time

A: Vacuum pumping

Most of the air can be pumped out in a short time, greatly reducing gas filling time.

B: Inert gas introduction (nitrogen or argon)

Users can set the upper and lower limits of oxygen content, and the equipment automatically starts and stops the inert gas switch, greatly saving gas consumption.

C: Oxygen content detection

A: Equipped with upper computer software, it can connect to a computer for real-time monitoring, recording, saving, and data export.

B: Original imported sensor, automatic temperature, zero point, and full-scale drift compensation.

C: Protection against high-concentration gas impact and sensor fault self-check function, safe and reliable.

D: Detection accuracy: ≤±3% (F.S)

E: Zero drift: ≤±1% (F.S/year)

F: Linearity error: ≤±1%



4: PLC system automatic gas replenishment

The equipment uses a PLC control system, which combines preset values and real-time detection to intelligently operate positive pressure to expel oxygen content during work and automatically replenish inert gas. This ensures the entire working process meets the requirements of material mixing, resulting in better mixing effects.
