Extrusora de doble husillo de escritorio para la fabricación de membranas de ultrafiltración de fibra hueca.

With the current urgent market demand for high-efficiency ultrafiltration technology, ultrafiltration membranes are widely used in industrial wastewater treatment, medical dialysis, and water purification systems. We are now introducing a solution for the efficient preparation of hollow fiber ultrafiltration membranes: the HTGD-11 desktop twin-screw extruder, equipped with a melt pump, water tank, and winding equipment.

What is a hollow fiber ultrafiltration membrane?

Simply put, a hollow fiber ultrafiltration membrane is like a microscopic filter. It is composed of many tiny hollow fibers, each with a diameter finer than a human hair. The surface of these hollow fibers is covered with tiny pores, the size of which can be precisely controlled according to requirements. When liquid passes through these pores, impurities and large molecules are trapped on the surface or inside the membrane, while pure liquid can pass through smoothly. Hollow fiber ultrafiltration membranes have many advantages, including high filtration accuracy, high flux, and strong resistance to fouling, playing a crucial role in water purification, drug separation, and biomedicine.

Desktop Twin-Screw Extruder Performance Features:

1. High-Efficiency Mixing and Plasticizing: The twin-screw design ensures thorough and uniform mixing and plasticization of materials, forming a stable melt and guaranteeing consistent ultrafiltration membrane performance.
2. Precise Temperature Control: Advanced temperature control technology precisely controls the temperature of each section, ensuring material quality, preventing problems, extending equipment life, and reducing costs.
3. Compact Desktop Design: Occupies little space, suitable for laboratory research and development, small-scale production, and teaching demonstrations. Easy to move and install, offering high flexibility.

The Melt Pump is Key to Stable Extrusion:

1. Improved Product Quality: Eliminates pulsation caused by extruder screw rotation, ensuring smooth melt entry into the spinneret and improving the overall quality of the ultrafiltration membrane.
2. Precise Fiber Size Control: Precisely adjusts the hollow fiber diameter by controlling the rotation speed to meet the needs of different application scenarios.

The Water Tank and Rewinding Equipment Complete the Final Stage:

1. Water Tank Solidification: Cooling water rapidly solidifies and shapes the hollow fibers; parameters are adjustable to achieve optimal solidification results.
2. Neat Winding and Protection: The winding equipment neatly winds the ultrafiltration membrane, maintaining appropriate tension to ensure integrity and appearance quality, reducing damage and contamination.

Applications of the Hollow Fiber Ultrafiltration Membrane Experimental Line:

1. Scientific Research and Teaching: The HTGD-11 desktop twin-screw extruder and its supporting equipment provide an ideal experimental platform for ultrafiltration membrane research and teaching in universities and research institutions. It facilitates researchers in screening materials, optimizing formulations, and exploring processes, accelerating research and development. It also provides a visual demonstration of the preparation process, helping students understand the relationship between structure and performance, improving teaching effectiveness and practical skills.
2. Small-Scale Production and Customized Services: For small and medium-sized enterprises or startup teams, this equipment is ideal for small-scale and customized ultrafiltration membrane production. It allows for adjustments to formulations and processes as needed to produce hollow fiber ultrafiltration membranes. Its low investment cost, small footprint, and flexible production capabilities allow it to adapt to market changes and personalized needs, helping enterprises gain a competitive edge.

The HTGD-11 desktop twin-screw extruder, combined with a melt pump, water tank, and winding equipment, provides an efficient and convenient solution for the preparation of hollow fiber ultrafiltration membranes.
