What's the function of small twin screw extruder?
The small twin screw extruder is a kind of high efficiency polymer extrusion equipment which integrates mixing, plasticizing, extrusion and casting film.Its main USES are:
1. BlendingModification
Different types and brands of plastics are made into homogeneous plastic alloys or blends by extruding and blending to obtain polymer materials with specific properties.
2. FillingModification
Various inorganic fillers, such as calcium carbonate and talc powder, are added into the plastic to improve the physical and mechanical properties of materials while greatly reducing the cost of products.
3. Composite Modification
Mixing various additives, such as stabilizers, flame retardants and coloring agents, into plastics to obtain new materials with uniform dispersion and specific functions.
4. TougheningModification
In order to improve the physical and mechanical properties of composite materials, reinforced components such as glass fiber and carbon fiber are added into the plastic matrix.
5. Film/Sheet Extrusion
This device can realize extrusion flow of polymer and its composites, calendering, preparation of high quality can stretch film, can realize flow of polymer material ductility test, research and development of new product formula, production process parameters optimization, a narrow thin film small scale production, etc
6. Exhaust, Devolatilize
In the process of plasticizing and mixing, various volatile components, such as monomers, solvents, water, polymers, etc. remaining in the polymer can be quickly eliminated and the performance of the product can be improved.
7. Screw Restructuring
By optimizing screw assembly, this small twin screw extruder can be used in the mixing and granulation of various powder materials and thermosetting plastics as well as the reaction extrusion of polymers and other special fields.
