Small desktop twin-screw extruders have the characteristics of small size and easy operation. They have a wide range of functional applications in the fields of material research and development, teaching experiments, small batch production, etc., as follows:
Material research and development field
Polymer blending modification: Different types of polymers can be blended, such as blending polypropylene (PP) with polyethylene (PE) to improve the performance of the material. By adjusting the blending ratio, screw speed, temperature and other parameters, the influence of different factors on the performance of the blend is studied, and new materials with specific properties are developed.
Adding functional additives: Add various functional additives to the polymer, such as flame retardants, toughening agents, antioxidants, etc., to study the dispersion of additives in the polymer and the influence on the material properties. Taking the addition of flame retardants to polystyrene (PS) as an example, the flame retardant performance changes of the material under different flame retardant addition amounts can be explored through a small desktop twin-screw extruder.
Nanomaterial composite: Composite nanomaterials with polymer matrices to prepare nanocomposites. For example, nano-silica is compounded with polymethyl methacrylate (PMMA), and the shearing and mixing effects of the twin-screw extruder are used to evenly disperse the nanoparticles in the polymer matrix, and the improvement effect of nanomaterials on the mechanical and optical properties of polymers is studied.
Teaching Experiment Field
Basic Teaching Demonstration: In the teaching of polymer materials related majors, as a teaching device, students can intuitively understand the working principle, operation method and basic process of polymer processing of the lab twin-screw extruder, and enhance students’ understanding of theoretical knowledge.
Student Independent Experiment: Students can use a small desktop twin-screw extruder to conduct self-designed experiments, such as exploring the effects of different processing technologies on material properties, and cultivating students’ practical ability and innovative thinking.
Scientific Research Project Assistance: Provide an experimental platform for students’ scientific research projects or course designs, and support students to carry out some small scientific research explorations, such as the synthesis and processing research of new polymer materials.
Small Batch Production Field
Special Material Preparation: Used for small batch preparation of some special materials, such as biodegradable materials, shape memory materials, etc. These materials have special applications in the fields of medical treatment, aerospace, etc., and can be produced in small trials through small desktop twin-screw extruders to meet the small needs of specific users.
Customized product production: produce small batches of customized products for the customized needs of some special customers, such as plastic parts and electronic packaging materials with special performance requirements, and quickly respond to the personalized needs of the market.
Sample production: make product samples for enterprises or research institutions for product display, performance testing, market promotion, etc. For example, plastic pipe and profile manufacturers can use small desktop twin-screw extruders to make samples of different specifications and performances for customers to select and test.
The prices of small desktop twin-screw extruders are roughly as follows:
Basic entry type: such as the CT30/15 laboratory micro-mini conical twin-screw extruder on Taobao, the price is as low as 500 yuan. This type is usually simple in structure and is suitable for scenes with low extrusion requirements, simple experiments or teaching demonstrations.
Conventional functional type: like the Baopin BP-8177-BT desktop twin-screw extruder, the price is 145,000-150,000 yuan. The screw diameters are 20, 25, 30 and other specifications, with basic mixing, plasticizing, dispersing and other functions, and can be used for small batch material experiments and some simple material tests.
Mid-to-high-end configuration: Nanjing kerke Extrusion Equipment Company’s laboratory twin-screw extruder, priced at 250,000 yuan. This type of product has a high degree of automation, a variety of advanced functions and precise control parameters, and can meet more complex material research and development and production needs.
