Applications
F.A.Q.
Q1: What materials can the 2L vacuum sigma mixer handle?
A1: It is suitable for sticky, viscous, and paste-like materials, including adhesives, polymers, sealants, ceramic paste, and silicone formulations.
Q2: Does this mixer come with a vacuum pump?
A2: No, the machine is equipped with a vacuum valve and gauge, but the pump is not included. Customers can connect their own pump to reach a vacuum level of -0.09 MPa.
Q3: What is the advantage of electric heating with jacket design?
A3: The electric heating jacket allows precise temperature control, helping to maintain uniform heat distribution during the mixing process and preventing product degradation.
Q4: How does the safety interlock work?
A4: The mixer is equipped with a safety limit switch. If the lid is opened during operation, the motor automatically stops, ensuring operator safety.
Q5: What is the discharge method?
A5: This unit uses manual tilting discharge, which is convenient for small batch production and laboratory use.
