Description

technical field [0001] The invention belongs to the field of nanofiber production equipment, in particular to a nanofiber preparation tool with high adsorption performance. Background technique [0002] Nanofiber refers to a thread-like material with a diameter of nanoscale and a large length with a certain aspect ratio. In addition, fibers that are modified by filling nanoparticles into ordinary fibers are also called nanofibers. In a narrow sense, the diameter of nanofibers is between 1nm and 100nm, but in a broad sense, fibers with a diameter of less than 1000nm are called nanofibers. Nanofibers have a wide range of uses, such as implanting nanofibers into the surface of the fabric, a stable gas film can be formed to make an amphiphobic interfacial fabric, which can not only waterproof, but also prevent oil and dirt; made of nanofibers Advanced protective clothing, the fabric is porous and has a membrane, which not only allows air to pass through, is breathable, but also...

AI Technical Summary

Problems solved by technology

The process of preparing nanofibers with high adsorption performance is the process of raw material mixing and stirring, extrusion, spinning, coating, drying, and spinning. There are many technical defects in the prior art: (1) the existing mixing and stirring The equipment cannot meet the mixing and stirring of the new raw liquid formula of nanofiber filaments, and the same mixing equipment is used for mixing, which will cause pollution between components in different reaction stages

(2) The raw material is not stirred uniformly in the existing stirring device, resulting in insufficient reaction of the stock solution, which affects the adsorption performance of nanofibers

(3) Existing extruder equipment is usually provided with only a single extrusion port, and the raw liquid entering the extruder can only be extruded from a single exit, and the extrusion efficiency is low

(4) The extruder is not equipped with heating and heat insulation devices, and the proper temperature cannot be guaranteed to keep the principle in the best extrusion state when the raw liquid is extruded. The extrusion process is not smooth, and even affects the physical and chemical properties of the raw liquid.

In the former, when the fiber filaments fall on the ground and then the fiber filaments are transported, there are often chaotic knots between the fiber filaments, which affects the winding quality and efficiency of the fiber filaments; when the fiber filaments are directly conveyed by the transfer roller, There is no buffer stage between the fiber filament and the conveying roller, and the fiber filament is prone to generate large stress, which may easily cause the fiber filament to break

The winding quality of fiber filaments is poor, and the system operation stability is poor
