Description

technical field [0001] The invention belongs to the field of packaging material experiment equipment, in particular to a multifunctional integrated laboratory-specific electrostatic spinning machine. Background technique [0002] With the rapid development of research on packaging materials, one-dimensional nanomaterials have become a research hotspot in the field of materials due to their large surface area and excellent performance. As a device for making one-dimensional nanomaterials, the electrospinning machine has become a popular object of experimental research. [0003] An electrospinning machine usually consists of a DC high-voltage power supply, an iron stand, a receiving roller for collecting nanofilaments, and a needle tube filled with a solution. Its main working principle is that the material to be produced and the polymer carrier are mixed into a certain ratio solution. Due to the characteristics of the polymer itself, the polymer solution is usually relativel...

AI Technical Summary

Problems solved by technology

[0004] The structure and function of the existing electrospinning machine are relatively simple, and there are still the following disadvantages: 1. The installation position and angle of the syringe cannot be adjusted at will, resulting in the injection position and angle of the solution in the syringe. The spraying needs of solutions with different viscosities have a small scope of application. In order to meet the needs of the experiment, various electrospinning machines of different specifications need to be prepared in the laboratory, which not only increases the cost of the experiment, but also is not conducive to the scientific layout of the laboratory; 2. For The receiving part of the nano filaments ejected from the receiving syringe is made of a receiving roller, and the receiving form is relatively simple.
