Laboratory Small Sigma Mixer Kneader Machine
Scope of application of laboratory small kneading machine
The laboratory kneading machine is widely used in experiments such as mixing, kneading, crushing, stirring, vulcanization, and re polymerization of high viscosity and high elastoplastic materials. The laboratory kneading machine has the advantages of uniform stirring, high kneading efficiency, etc.
The laboratory kneading machine has a wide range of functions, varieties, and applications, especially suitable for pre production experiments and testing in industries such as chewing gum, bubble gum, toothpaste, plastics, rubber, silicone rubber, dyes, pigments, inks, food adhesives, pharmaceuticals, building coatings, carbon, fiber, high viscosity sealants, neutral glass adhesives, aluminum silver paste, silicone gel, pulp, cellulose, battery pastes, dyes, silicone resins, cosmetics, etc.
A laboratory small-scale kneading machine is a device that utilizes a pair of interlocking and rotating blades (usually in a Z-shape) to generate strong shear forces, allowing semi dry or rubber like viscous plastic materials to react rapidly and achieve uniform mixing and stirring. The laboratory kneading machine consists of six main parts: kneading section, machine base section, hydraulic system, transmission system, vacuum system, and electronic control system.
Chinese name: Laboratory Kneading Machine
Foreign name: Kneading machine
Usage: For laboratory use
Type: Hybrid equipment
Advantages: Small batch trial, easy operation, small size
Function: Crushing, stirring, kneading, mixing
Discharge methods: flip cylinder, ball valve, hydraulic, screw extrusion, etc
Vacuum degree: -0.098
Small kneading machines are widely used in various industries such as chemical, pharmaceutical, food, rubber, plastic, and cosmetics, for the mixing, kneading, dispersing, and reacting of high-viscosity, elastoplastic materials. Their core function is to apply shear, extrusion, folding, and other effects to the materials through the differential rotation of Z-shaped or Σ-shaped mixing paddles, achieving uniform mixing.
1. Main application industries and typical materials: Chemical industry
Used for producing silicone rubber, sealant, hot melt adhesive, ink, pigment, dye, resin, etc.
Typical materials: silicone resin, BMC (bulk molding compound), CMC (carboxymethyl cellulose).
Pharmaceutical and cosmetics industry
Prepare medicinal ointment, soft ointment, paste, medical silicone, chewing gum base, bubble gum, cosmetic cream, etc.
The equipment is required to have good sealing and cleanliness to prevent cross-contamination.
Food industry
It is applied to the mixing of high-viscosity materials such as chocolate, jam, condiments, and food gum base.
The contact parts of the equipment must be made of food-grade stainless steel, meeting hygiene standards.
New energy and battery materials
Used for small-batch formula development and homogenization processing of battery slurry (such as lithium battery cathode and anode materials) in the laboratory.
Rubber and plastic, as well as composite materials
Used for mixing and defoaming of carbon materials, cellulose, plastic modifications, color masterbatch, etc., especially suitable for removing bubbles in vacuum kneading machines.
Q: Can the Laboratory Sigma Kneader Machine handle abrasive materials?
A: Standard models are not recommended for highly abrasive materials (e.g., silicon carbide powders) as they cause premature blade wear. Upgraded versions with tungsten carbide - coated blades can extend service life by 3 - 5 times for such applications.
Q: What is the cleaning process after use?
A: The chamber and blades can be disassembled without tools. For water - soluble materials, warm soapy water suffices; for oils and greases, isopropyl alcohol or citrus - based solvents are effective. A high - pressure air gun aids in drying hard - to - reach areas.
Q: How accurate is the temperature control for sensitive materials?
A: The PID - controlled system maintains temperature within ±2°C of the setpoint, even when processing materials with high heat capacity, such as waxes.
