Q1: What is the difference between a sigma mixer and a Z blade mixer?
A1: Both names refer to the same type of kneader. The blades have a Z or sigma shape, designed for mixing high-viscosity materials efficiently.
Q2: Can the 2L vacuum Z blade mixer be used in laboratories?
A2: Yes, this compact 2L model is ideal for laboratory research, pilot testing, and small-scale production of specialty materials.
Q3: What is the blade speed range?
A3: The blades run at two different speeds: fast (0–42 rpm) and slow (0–35 rpm), controlled by a frequency inverter for flexible mixing.
Q4: What material is used for the contact parts?
A4: All product contact parts are made of stainless steel 316 with mirror polish, ensuring durability, corrosion resistance, and easy cleaning.
Q5: What industries use this type of mixer?
A5: This kneader is widely applied in adhesives, silicone rubber, chewing gum, sealants, ceramic pastes, and other formulations that require vacuum mixing under controlled temperature.
