Overview
The Z-type vacuum kneading machine in a small laboratory is an efficient mixing equipment designed for high viscosity and high elastic-plastic materials (such as silicone rubber, butyl rubber, hot melt adhesive, sealant, chewing gum, etc.) in the research and development and small-scale testing stages. It integrates mixing, kneading, and defoaming, and has the characteristics of compact structure, precise operation, and strong sealing. It is widely used in new materials, chemical industry, food, medicine, and electronic packaging fields.
Product Details
Small laboratory Z-type vacuum kneading machineIt is an efficient mixing equipment designed specifically for high viscosity and high elastic-plastic materials (such as silicone rubber, butyl rubber, hot melt adhesive, sealant, chewing gum, etc.) in the research and development and small-scale testing stages. It integrates mixing, kneading, and defoaming, and has the characteristics of compact structure, precise operation, and strong sealing. It is widely used in new materials, chemical industry, food, medicine, and electronic packaging fields.
1、 Core structure and working principle
Z-shaped mixing blade design
A pair of Z-shaped or ∑ - shaped stirring blades are used to rotate in opposite directions at different speeds (main shaft 20-40 RPM, secondary shaft 10-20 RPM) in a W-shaped mixing tank, forming strong shear, stretching, folding, and compression effects to achieve deep kneading and uniform dispersion of materials.Vacuum defoaming system
Equipped with a vacuum pump, the working vacuum degree can reach ≤ -0.094 MPa (about -0.1 MPa), effectively removing bubbles and volatile matter trapped in the material during the mixing process, significantly improving the density, transparency, and mechanical properties of the final product. Especially suitable for materials such as HTV silicone rubber and neutral glass adhesive that require high air tightness.Temperature Control System
The mixing tank has a jacket structure and supports electric heating, thermal oil heating, or water cooling. The temperature control accuracy can reach ± 2 ℃, ensuring stable and controllable reaction process. Some models have multi zone independent temperature control function to meet complex process requirements.Sealing and Material Safety
The mixing shaft adopts a vacuum sealed structure to prevent filler particles from entering the cylinder body and ensure material purity; All parts in contact with materials are made of SUS304 or 316L stainless steel, which is corrosion-resistant, easy to clean, and meets the production requirements of food grade and pharmaceutical grade.
